Description

Fixed clamp

A fixing clamp, in particular a fixing clamp used for a chassis of a display device.

Generally speaking, the fixing fixtures used for display devices use a single clamp seat and a single screw assembly to lock and fix with multiple components, and the waterproof foam on the edge of the chassis is pressed against the screw to achieve a waterproof effect. However, as the size of the chassis increases, more components are required, increasing the user's workload. In addition, when using multiple sets of clamp seats and multiple sets of screws, some of the screws may be skewed, causing uneven force on the waterproof foam, thereby affecting the waterproof function of the chassis.

In view of this, according to one embodiment, a fixing clamp is provided, which is suitable for a chassis. A first groove portion and a second groove portion are provided on the wall of the chassis. The fixing clamp includes a bracket, a base, a first locking fixture and a second locking fixture. The bracket includes a bracket body, a first assembly portion and a second assembly portion, the first assembly portion and the second assembly portion are located at two opposite ends of the bracket body, the first assembly portion has a first clamping groove and a first locking groove, and the second assembly portion has a second clamping groove and a second locking groove. The base includes a base body and a connecting member, the connecting member is provided on the base body, and connects the bracket and the base. The first locking fixture is locked in the first locking groove. The second locking fixture is locked in the second locking groove. When the first locking fixture and the second locking fixture are pressed against the base, the base and the bracket are kept away from each other. The first assembly part and the second assembly part are respectively assembled to the first slot part and the second slot part, and the wall surface of the chassis is clamped to the first clamping slot and the second clamping slot.

In some embodiments, the connecting member is a magnet. When the first locking member and the second locking member move in a direction to bring the base and the bracket closer to each other, the magnet is attracted by magnetic force to connect the bracket and the base. When the first locking member and the second locking member press against the base and move the base and the bracket away from each other, the magnet separates from the bracket.

As shown in Figures 4A and 4B, the fixing fixture 100 includes a bracket 110, a base 130, a first locking member 150 and a second locking member 160. In this embodiment, as shown in FIG. 2 and FIG. 3 , the fixing fixture 100 is used to fix the chassis 600. When the chassis 600 is fixed to the assembly surface 1000, the fixing fixture 100 can be used to apply pressure to the assembly surface 1000, so that the chassis 600 is evenly pulled away from the assembly surface 1000, so that the waterproof member 630 at the edge is evenly and tightly pressed against the assembly surface 1000 to achieve a waterproof effect. The chassis 600 is, for example, a chassis of a display device, but is not limited thereto.

As shown in FIG. 4A and FIG. 4B , the bracket 110 includes a bracket body 111, a first assembly part 112 and a second assembly part 113. The first assembly part 112 and the second assembly part 113 are located at opposite ends of the bracket body 111. The first assembly part 112 has a first clamping groove 1121 and a first locking groove 1122, and the second assembly part 113 has a second clamping groove 1131 and a second locking groove 1132. In this embodiment, the first clamping groove 1121 and the second clamping groove 1131 are grooves recessed from the wall surface of the first assembly part 112 and the second assembly part 113, respectively, and the first locking groove 1122 and the second locking groove 1132 are holes with threads.

The base 130 includes a base body 131 and a connecting member 132. The connecting member 132 is disposed on the base body 131 and connects the bracket 110 and the base 130. In this embodiment, there are two connecting members 132, but this is not limited to one or more connecting members. In this embodiment, the bracket 110 and the base 130 are prevented from being separated by the connecting member 132. The connecting member 132 has a variety of implementations. The detailed structure of the connecting member 132 will be described in detail later.

The first locking member 150 is locked in the first locking groove 1122. The second locking member 160 is locked in the second locking groove 1132, and one of the first locking member 150 and the second locking member 160 can be selectively locked and pressed against the base 130. In this embodiment, the first locking member 150 and the second locking member 160 are, for example, screws, which are locked in the first locking groove 1122 and the second locking groove 1132 by screwing, and the ends of the first locking member 150 and the second locking member 160 extending toward the base 130 are locked to the base body 131 and pressed against the base body 131. In this embodiment, as shown in FIG. 4A , by rotating the first locking member 150 and the second locking member 160 out of the first locking groove 1122 and the second locking groove 1132, respectively, that is, rotating the first locking member 150 and the second locking member 160 toward the upper direction of the figure, the base 130 and the bracket 110 can be brought closer to each other. As shown in FIG. 4B , by rotating the first locking member 150 and the second locking member 160 into the first locking groove 1122 and the second locking groove 1132, respectively, that is, rotating the first locking member 150 and the second locking member 160 toward the lower direction of the figure, the first locking member 150 and the second locking member 160 can be locked and pressed against the base 130. At this time, the base 130 is pushed up by the first fastener 150 and the second fastener 160, so that the base 130 and the bracket 110 are separated from each other. In this embodiment, it is illustrated that the base 130 and the bracket are separated from each other by the first fastener 150 and the second fastener 160, but it is not limited to this. The base 130 and the bracket 110 can also be separated from each other by only the first fastener 150 or the second fastener 160.

In this embodiment, the base 130 includes a first positioning portion 1311 and a second positioning portion 1312. The first positioning portion 1311 and the second positioning portion 1312 are respectively arranged corresponding to the first locking member 150 and the second locking member 160 to accommodate the first locking member 150 and the second locking member 160. The first positioning portion 1311 and the second positioning portion 1312 are, for example, grooves with threads. When the first locking member 150 and the second locking member 160 are screwed in, one end of the first locking member 150 and the second locking member 160 is respectively locked in the first positioning portion 1311 and the second positioning portion 1312 and abuts against the base 130.

Please refer to Figures 2, 3 and 4A at the same time. In this embodiment, the wall 610 of the chassis 600 is provided with a first groove 611 and a second groove 612. The first assembly part 112 and the second assembly part 113 are inserted into the chassis 600 through the first groove 611 and the second groove 612 respectively, and the wall 610 of the chassis 600 is clamped to the first clamping groove 1121 and the second clamping groove 1131.

As shown in Figs. 2, 3 and 4A, the case 600 is a case 600 of a display device, and the display device has a front frame 620 with a larger area than the case 600. When the display device is to be assembled on the assembly surface 1000, the case 600 is passed through the assembly port from one side of the assembly surface 1000, so that the front frame 620 abuts against one side of the assembly surface 1000, and the first groove 611 and the second groove 612 of the wall 610 of the case 600 are exposed on the other side of the assembly surface 1000. Then, the first assembly part 112 and the second assembly part 113 of the fixing fixture 100 are assembled to the first groove 611 and the second groove 612 respectively on the other side of the assembly surface 1000. Then, the first locking member 150 and the second locking member 160 are screwed in to press against the base 130, so that the base 130 provides an even downward pressure on the other side of the assembly surface 1000, so that the chassis 600 is evenly pulled away from the assembly surface 1000. In this way, the waterproof member 630 located on one side of the assembly surface 1000 and the edge of the display device front frame 620 is evenly and tightly pressed against the assembly surface 1000 to achieve a waterproof effect. In this embodiment, the waterproof member 630 is, for example, waterproof foam.

Furthermore, since the connecting member 132 connects the bracket 110 and the base 130, when the first assembly part 112 and the second assembly part 113 of the fixing fixture 100 are respectively assembled to the first groove part 611 and the second groove part 612, that is, when the first locking member 150 and the second locking member 160 are screwed out, the bracket 110 and the base 130 will not be separated due to the connection of the connecting member 132. When the first locking member 150 and the second locking member 160 are respectively screwed into the first locking groove 1122 and the second locking groove 1132, there is no need to re-align the bracket 110 and the base 130, and the operation can be convenient.

Regarding the structure of the connecting member 132. In this embodiment, the connecting member 132 is a magnet. When the first locking member 150 and the second locking member 160 move in the direction of bringing the base 130 and the bracket 110 closer to each other, that is, when the first locking member 150 and the second locking member 160 are rotated out, the base 130 will be driven closer to the bracket 110. However, if the first locking member 150 and the second locking member 160 are continuously rotated out, the first locking member 150 and the second locking member 160 will be completely separated from the first positioning portion 1311 and the second positioning portion 1312, and the base 130 will fall. At this time, the bracket 110 and the base 130 can continue to be connected by the magnetic attraction of the connecting member 132. When the first locking member 150 and the second locking member 160 are screwed in to lock and press against the base 130, and the base 130 and the bracket 110 are moved away from each other, the connector 132 is separated from the bracket 110. In this way, even if the first locking member 150 and the second locking member 160 are screwed out, the bracket 110 and the base 130 can be connected through the connector 132. When the user wants to screw in the first locking member 150 and the second locking member 160, since the bracket 110 and the base 130 are connected through the connector 132, the user does not need to hold the bracket 110 and the base 130 separately, nor does it need to be re-aligned, so that the user can lock more conveniently.

In the first embodiment, the connecting member 132 is a magnet, but is not limited thereto. Please refer to FIG. 5, which is a three-dimensional schematic diagram of a fixing fixture according to a second embodiment. In the second embodiment, the bracket 210 includes a sliding portion 2111, and the connecting member 232 extends from the base body 231 toward the side facing the bracket 210 and has a sliding groove 2321, and the sliding portion 2111 is slidably disposed in the sliding groove 2321. When the first locking member 150 and the second locking member 160 are actuated in a direction to bring the base 230 and the bracket 210 closer to each other, the sliding portion 2111 slides along the sliding groove 2321 to a side of the sliding groove 2321 close to the base 230. When the first locking member 150 and the second locking member 160 are locked and pressed against the base 230, and the bracket 210 is moved away from the base 230, the sliding portion 2111 slides along the sliding groove 2321 to one side of the sliding groove 2321 away from the base 230. Thus, even if the first locking member 150 and the second locking member 160 are screwed out, the connection between the bracket 210 and the base 230 can be maintained through the sliding portion 2111 and the sliding groove 2321. And when the user wants to screw in the first locking member 150 and the second locking member 160, since the bracket 210 and the base 230 are connected through the connector 232, the user does not need to hold the bracket 210 and the base 230 separately, so that the user can lock more conveniently.

In the second embodiment, on the fixing fixture 200, the sliding portion 2111 has a screw 2112 and a locking hole 2113, the nut 2112A of the screw 2112 is located on one side of the connecting member 232, and the stud portion 2112B of the screw 2112 passes through the sliding groove 2321 and is locked in the locking hole 2113 from the other side of the sliding groove 2321. In this way, the bracket 210 can slide in the sliding groove 2321 through the screw 2112 and move relative to the base 230, so that the bracket 210 and the base 230 are close to or away from each other.

Please refer to FIG. 6. FIG. 6 is a three-dimensional schematic diagram of a fixing fixture according to a third embodiment. In the third embodiment, on the fixing fixture 300, the bracket 310 includes a through slot 3111, and the connecting member 332 extends from the base body 331 toward the side of the bracket 310 and passes through the through slot 3111. The connecting member 332 has a limiting portion 3321 at one end away from the base body 331. The first locking member 150 and the second locking member 160 are locked and pressed against the base 330, and when the bracket 310 is away from the base 330, the moving range of the bracket 310 relative to the base 330 can be limited by the limiting portion 3321. In addition, when the first locking member 150 and the second locking member 160 are screwed out, the connection between the bracket 310 and the base 330 can be maintained through the connector 332 and the limiting portion 3321 at the end thereof. Similarly, when the user wants to screw in the first locking member 150 and the second locking member 160, since the bracket 310 and the base 330 are connected through the connector 332, the user does not need to hold the bracket 310 and the base 330 separately, so that the user can lock more conveniently, and the limiting portion 3321 can be used to prevent the bracket 310 from being separated from the base 330. In this embodiment, the limiting portion 3321 is, for example, a rectangular block, but is not limited thereto.

Please refer to FIG. 7 and FIG. 8. FIG. 7 is a three-dimensional schematic diagram of a fixing clamp according to a fourth embodiment. FIG. 8 is a schematic diagram of the use of the fixing clamp of FIG. 6 and FIG. 7. In the fourth embodiment, in addition to the first locking member 450 and the second locking member 460, the fixing clamp 400 further includes a third locking member 470, and the bracket 410 further includes a third assembly part 414, and the third assembly part 414 is located between the first assembly part 412 and the second assembly part 413, and has a third clamping groove 4141 and a third locking groove 4142. The third locking member 470 is locked in the third locking groove 4142. When the third locking member 470 is locked and pressed against the base 430, the base 430 and the bracket 410 can be close to or away from each other. In the fourth embodiment, as shown in FIG8 , the wall of the chassis 600 is provided with a third groove 613, the third assembly portion 414 of the bracket 410 is assembled to the third groove 613, and the wall 610 of the chassis 600 is clamped to the third clamping groove 4141. In this way, the fixing fixture 400 can be provided with a third assembly portion 414 according to the size of the chassis 600, so as to be applied to the long side of the chassis 600.

For example, as shown in FIG8 , the longer side of the chassis 600 can be fixed by a longer fixing clamp 400, while the shorter side can be fixed by a shorter fixing clamp 300. In this way, it is possible to avoid the need to use multiple sets of shorter fixing clamps 300 on a long side, thereby reducing the number of assembly steps for the user. In addition, compared to multiple sets of shorter fixing clamps 300, a single set of longer fixing clamps 400 can apply pressure to the assembly surface 1000 more evenly, so that the chassis 600 is evenly pulled away from the assembly surface 1000, so that the waterproof member 630 at the edge is evenly and tightly pressed against the assembly surface 1000.

In addition, the first to fourth embodiments illustrate a fixing clamp that is detachably assembled to the chassis 600, but are not limited to this. Please refer to Figures 9 to 13.

Figure 13 is a cross-sectional view along the symbol C-C in Figure 12. In the fifth embodiment, the fixing clamp 700 includes a bracket 710, a base 730 and a locking member 750. The bracket 710 includes a bracket body 711, a movable portion 712 and an assembly portion 713. The movable part 712 and the assembly part 713 are located at two opposite ends of the bracket body 711. The base 730 includes a base body 731. The locking member 750 is locked to the movable part 712, and one end of the locking member 750 is locked to the base body 731. When the locking member 750 abuts against the base body 731, the base 730 and the bracket 710 are separated from each other. The wall 810 of the chassis 800 is provided with a groove 811, and the assembly part 713 of the bracket 710 is assembled to the groove 811 by screwing, and the movable part 712 is selectively accommodated in the groove 811 or separated from the groove 811. As shown in FIG. 9 , in the fifth embodiment, the fixing clamp 700 is pivoted to the groove 811 through the assembly part 713 so that the fixing clamp 700 is integrated with the chassis 800.

As shown in FIG10 and FIG11 , before the case 800 is fixed, the fixing clamp 700 can be stored in the groove 811. As shown in FIG12 and FIG13 , when the case 800 is fixed, the fixing clamp 700 can be pivoted relative to the groove 811 so that the movable portion 712 leaves the groove 811. Then, by screwing in the locking member 750, one end of the locking member 750 pushes the base 730 so that the base 730 is away from the bracket 710, and the base 730 is pressed on the assembly surface 1000, so that the case 600 is evenly pulled away from the assembly surface 1000, so that the waterproof member 830 at the edge is evenly and tightly pressed against the assembly surface 1000, thereby achieving a waterproof effect. In this way, by integrating the fixing clamp 700 with the chassis 800, the user does not need to assemble the fixing clamps one by one.
