Referring to Fig. 1 and Fig. 2, a preferred embodiment of the combination device 100 without tools of the present invention is applied to the main body casing of a desktop computer, and can accommodate and position a fixed part (such as a peripheral device) In this example, an optical disc drive 7 is used as an example for the peripheral device. The opposite sides of the optical disc drive 7 are respectively provided with a plurality of fixing holes 71 originally designed for screw screw locking, and the main body casing includes a frame body 6. The body 6 is formed with two supporting walls 61 matching the width of the optical disc drive 7, so that a space for the optical disc drive 7 is formed between the two supporting walls 61, and each supporting wall 61 is provided with a plurality of alignment holes for the fixing holes 71 of the optical disc drive 7. Through hole 62, in this embodiment, in order to adapt to different types of fixed parts, for example, peripheral devices such as optical disk drives with operation panels or hard disk drives without operation panels, due to their different sizes, the fixed parts are in different positions. The positions of the required through holes 62 on the support wall 61 may also be slightly different, so it is necessary for this purpose that two other through holes 62' arranged in sequence and equidistantly are also provided at the positions adjacent to the through holes 62 in the length direction of the support wall 61. and 62″ to provide the function of the fixed part to elastically adjust the fixed position, but if the fixed part does not need to adjust the fixed position, the support wall 61 only needs to be provided with a single through hole 62 corresponding to the fixed hole 71 of the optical disc drive 7. Can.

The combining device includes a clamping part 1 and a pressing unit.

The engaging part 1 includes a rectangular body 11, the body 11 has a top surface 111 and a bottom surface 112 opposite to the top surface 111 to approach the corresponding support wall 61, and protrudes from the bottom surface 112 of the body 11. The hole 62 is used to insert the insertion portion 12 into the fixing hole 71 of the optical disc drive 7 .

The pressing unit includes a pressing part 2 , a pivot unit and a buckle unit. The pressed part 2 is a bent rod-shaped body, which forms a horizontal pivot section 21, a first connecting section 22 vertically connecting one end of the pivot section 21, a vertically connecting the first connecting section 22 and the other. One end and the second connecting section 23 parallel to the pivoting section 21 but shorter in length than the pivoting section 21, and a pressing section vertically connected to the other end of the second connecting section 23 and extending away from the pivoting section 21 24, and a handle section 25 that is connected to the end of the pressing section 24 and extends in a ring shape. The pivoting unit has two supporting plates 3 connected to the supporting wall 61 and spaced side by side. In this example, the supporting plates 3 are formed from the supporting wall 61 in a stamping manner, and each supporting plate 3 has a shaft hole. 31. The buckle unit has a hook plate 4 protruding from the support wall 61 , and in this example is formed from the support wall 61 by stamping.

When combined, the pivot section 21 of the pressed part 2 passes through the shaft hole 31 of the second support plate 3, so that the pressed part 2 can rotate relative to the support wall 61 with the pivot section 21 as the rotation axis, resulting in the pressed part 2 can be in a pressing position close to the support wall 61 to clamp the engaging member 1 therebetween (the position shown after assembly in FIG. 1 ), and an open position away from the support wall 61 (the position shown in FIG. 2 ). The hook plate 4 can be used to hook the pressing section 24 close to the operating section 25 when the pressing piece 2 is in the pressing position, so that the pressing piece 2 cannot rotate under the condition of no force, so as to fix the pressing piece 2 relative to the position of the support wall 61.

Referring to Fig. 1 and Fig. 3, when assembling the optical disc drive 7 to the frame body 6, first make the pressing part 2 be in the open position (as shown in Fig. The connection part 12 does not pass through the corresponding through hole 62, and then, the user only needs to align the fixing hole 71 of the optical disc drive 7 with the through hole 62, and then let the insertion part 12 of the clip 1 pass through the through hole 62 and enter In the fixing hole 71 of the optical disk drive 7, and apply force to the handling section 25 of the pressing part 2 with bare hands to drive the pressing part 2 to rotate around its pivot section 21, so that the pressing part 24 of the pressing part 2 contacts on the On the top surface 111 of the engaging part 1, a pressure is applied to the engaging part 1 in the direction of the supporting wall 61, and finally the pressing section 24 is buckled under the hook plate 4 to fix the position of the pressing part 2, so that by means of the snap The insertion part 12 of the joint part 1 is inserted into the fixing hole 71 of the optical disc drive 7 to form an interference effect. Under the action of the clamping part 1 being firmly fixed on the support wall 61 under the pressure of the pressing part 2, the optical disc The driver 7 is relatively fixed on the support wall 61 .

When dismounting the optical disk drive 7 from the frame body 6, the user only needs to apply force to the handling section 25 of the pressed part 2 with bare hands, so that the pressing section 24 of the pressed part 2 is disengaged from the buckle of the hook plate 4, and the The insertion portion 12 of the engaging member 1 withdraws from the fixing hole 71 of the optical disc drive 7, and the optical disc drive 7 can be taken out from the frame body 6 without interference.

Referring to Fig. 1 again, the top surface 111 of the body 11 of the engaging member 1 can be further provided with a surrounding wall 13 slightly protruding from the top surface 111 along its edge, and the surrounding wall 13 is formed with two parallel long side sections 131 and two parallel The short side section 132, the corresponding position of the two long side sections 131 is provided with a card slot 14 for the pivoting section 21 of the pressed part 2 to engage, and a short side section 132 is provided with a pressing section for the pressed part 2 24 through the slot 15, the purpose of which is to enable the clamping part 1 and the pressed part 2 to be fixed relative to each other in advance. The through hole 62 increases the convenience of use.

In addition, as shown in Figure 4, and with reference to Figures 1 and 2, based on the need for the above-mentioned optical disk drive 7 to elastically adjust its fixed position with the frame body 6, the engaging part 1 is fitted with the slot 14 on the surrounding wall 13 through The spacing of the holes 62, 62' and 62" is designed with two draw-in slots 14' and 14" which are parallel to the draw-in slot 14 in sequence. Therefore, if the fixed positions of the optical disk drive 7 and the support wall 61 are to be changed, for example If the fixing hole 71 of the optical disk drive 7 is changed to align with the through hole 62", it is only necessary to make the slot 14" of the engaging part 1 correspondingly engage with the pivoting section 21 of the pressing part 2, and the When the pressing part 2 drives the engaging part 1 to rotate, the insertion part 12 of the engaging part 1 can be naturally inserted into the fixing hole 71 of the optical disc drive 7 through the through hole 62″ to form interference positioning, and adjustment can be achieved. The effect of the fixed position of the optical disc drive 7 .

In addition, as shown in FIG. 2 , the coupling device 100 may further include a buffer member 5 covering the insertion portion 12 of the engaging member 1. The buffer member 5 is made of a material with certain compressive elasticity such as rubber. When the clamping part 1 is pressed at the pressing position, the buffer part 5 can pass through the through hole 62 along with the insertion part 12 and be compressed to closely contact the side of the optical disc drive 7 and the bottom surface 112 of the clamping part 1 (as shown in FIG. 3 As shown), therefore, when the disc drive 7 moves relative to the support wall 61 due to the rocking of the frame body 6, the buffer member 5 will absorb the impact force generated by the relative movement, so as to strengthen the fixing effect of the disc drive 7. On the other hand, when the user releases the pressing part 2 from the hook plate 4 so that there is no pressure on the engaging part 1, the buffer part 5 can release the elastic recovery force generated by its previous compression deformation, and automatically The insertion part 12 of the engaging part 1 is bounced out of the fixing hole 71 of the optical disc drive 7 in a timely manner, so that the effect of automatic detachment of the engaging part 1 can be formed, and the further convenience of the user's operation can be improved.

Furthermore, the above-mentioned engagement method of the engaging member 1 using the slots 14, 14', 14" and the pivoting section 21 of the pressed part 2 is mainly to facilitate the engaging of the engaging member 1 in the matching through holes 62, 62' or 62" position to change the combined position with the pressing part 2, the engaging part 1 can be directly removed from the pressing part 2, and the pivoting section 21 of the pressing part 2 does not need to disengage from the shaft hole 31 of the bearing plate 3. However, the positions of the slots 14, 14', 14" can also be replaced by pivot holes 16, 16', 16" (as shown in Figure 5), and the aforementioned functions can still be fully achieved. When changing the combined position with the pressed part 2, the pivotal section 21 needs to be separated from the shaft hole 31 of the bearing plate 3 at least on one side, and then penetrate into the corresponding pivot hole 16, 16' or 16" of the engaging part 1, is another embodiment of the present invention.

To sum up the above, the tool-free combination device 100 of the present invention and the computer mainframe housing to which the combination device 100 is applied, the user manually operates the pressing part 2 that rotates relative to the supporting wall 61 to fix the engaging part 1 The pressure, and then the insertion part 12 of the engaging part 1 is inserted into the fixing hole 71 of the fixed part through the through hole 62 of the supporting wall 61 to form an interference positioning effect, so that the fixed part can be firmly combined with the frame body 6 In fact, regardless of assembly or disassembly, the user can completely complete without the assistance of tools, which greatly improves the convenience of use, so the purpose of the present invention can indeed be achieved.

However, the above-mentioned ones are only preferred embodiments of the present invention. Although the above-mentioned descriptions have specified the detailed structures of the engaging parts, pressing parts, pivotal units and buckling units, in fact, different configurations can be made as required. Form design, and the number of combining devices does not necessarily match the number of fixing holes of the fixed part, but only one or two sets of combining devices can be used on one of the supporting walls, and other tools-free tools can be used on the other supporting wall. The fixed structure of the present invention can also achieve the same purpose, so the scope of the present invention can not be limited by the embodiments, that is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the description of the invention should still belong to the present invention.
