The invention relates to a workbench for providing installation and use of an electronic device, in particular to a worktable capable of adjusting an elevation angle.

A docking station generally used for electronic equipment, whose function is a workbench that provides electronic equipment settings, such as the Republic of China Patent Certificate No. M245484 and the US Patent No. 7079338, all having a triangular support structure, but none of them can Adjust the support angle according to your personal preference. In addition, as disclosed in the Chinese Patent Publication No. 201007435, a worktable capable of adjusting an elevation angle is disclosed, the workbench including a support arm/support frame structure capable of adjusting a support angle by rotation.

However, since the support arm is fixed by the frictional force generated by the pivoting of the support arm, the support force generated is not sufficient. If the support is used on a touch screen, the user often presses the touch. The screen, so the power of the finger press often changes the tilt angle that the touch screen originally adjusted, so the user must constantly adjust to the original tilt angle, which is quite inconvenient to use.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a work table that can adjust an support angle and has an adjustable elevation angle with high support stability.

Therefore, the table for adjusting the elevation angle of the present invention comprises a base, a rotating base, an adjusting seat, and a positioning unit.

The rotating base can pivotally connect the base to an elevation angle of the base.

The adjustment base includes a fixed arm coupled to the base, and a telescopic arm slidable relative to the fixed arm, the fixed arm and the telescopic arm being supported between the base and the rotating base.

The positioning unit is connected to the fixed arm and the telescopic arm, and is switched between a fixed state and an active state with respect to the fixed arm. When the positioning unit is in the fixed state, the telescopic arm is fixed to the fixed arm, and the positioning is performed. When the unit is in the active state, the telescopic arm slides relative to the fixed arm.

The utility model has the beneficial effects that: in use, since the telescopic arm can be extended and contracted in the front-rear direction with respect to the fixed arm, when the user adjusts the support angle, the user can change the length of the adjustment seat to allow the user to The angle and distance between the rotating seats are adjusted to achieve fine adjustment effect, and can meet the operation requirements of each user in different heights and different operating angles. More importantly, the rotating seat does not support the angle of inclination formed by the frictional force at the pivotal connection with the base, and the adjusting seat can provide stable and inherent support on the back of the rotating base, so even the user's The finger is pressed hard from the front side of the rotating base, and the tilt angle is still not changed. Therefore, the user can use the tilt angle of the rotating base once in place, and can safely use it for a long time.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;

As shown in FIGS. 1, 2, 3 and 4, a preferred embodiment of the table 200 for adjusting the elevation angle of the present invention comprises a base 20, a rotating base 30, an adjustment base 40, and a positioning unit 50.

The base 20 includes an upwardly opening recess 21 and a plurality of ribs 22 located in the recess 21. The ribs 22 are spaced apart along the extending direction of the adjusting base 40. In actual manufacturing, the pedestal It is also possible to have only a single rib 22.

The rotating base 30 can be pivotally connected to the base 20 at an elevation angle with respect to the base 20, and can be used for providing an electronic device such as a flat display, a portable computer, and the like. The rotating base 30 includes at least one pivot 31. Considering the strength and cost of the material, the pivots 31 provided at two intervals in this embodiment can be used.

The adjusting base 40 includes a fixed arm 41 extending in the front-rear direction X and connecting the base 20, and a telescopic arm 42 sleeved on the fixed arm 41 in the front-rear direction X. The fixed arm 41 and the telescopic arm 42 are supported by the telescopic arm 42. Between the base 20 and the rotating base 30, the telescopic arm 42 is slidable relative to the fixed arm 41.

One end of the fixing arm 41 abuts against one of the ribs 22 of the recess 21 . The adjusting base 40 includes a cavity 411 extending in the front-rear direction X and opening forward. The fixing arm 41 has a fixing hole 412 . The chamber 411 is penetrated in the up and down direction Z.

The telescopic arm 42 is a hollow tubular body extending in the front-rear direction X and sleeved in the cavity 411, and includes a long perforation 421 corresponding to the fixing hole 412 and extending in the front-rear direction X. The telescopic arm 42 One end of the telescopic arm 42 is sleeved between the pivoting arms 31 and the other end of the telescopic arm 42 is sleeved in the fixed arm 41.

The positioning unit 50 connects the fixed arm 41 and the telescopic arm 42 and enables the telescopic arm 42 to be in a fixed state (as shown in FIGS. 4 and 5) with respect to the fixed arm 41 (FIG. 6, The positioning unit 50 includes an elastic member 51 disposed in the chamber 411 and abutting against the telescopic arm 42. A turntable 52 is mounted on the fixing hole 412, and a stopper 53 is located on the telescopic arm. The turntable 52 is connected to the fixing hole 412 through the long hole 421, a brake block 54 is disposed in the telescopic arm 42 and sleeved between the stopper 53 and the turntable 52, and two racks 55 The telescopic arm 42 is fixed to the fixed arm 41 when the positioning unit 50 is in the fixed state. When the positioning unit 50 is in the active state, the positioning unit 50 is located in the fixed state. The telescopic arm 42 slides relative to the fixed arm 41.

The elastic member 51 constantly provides the elastic force of the telescopic arm 42 to slide out of the fixed arm 41.

The turntable 52 has a connecting post 521 that passes through the fixing hole 412 and the long through hole 421 and is coupled to the stopper 53.

The racks 55 are located between the brake block 54 and the turntable 52. In the embodiment, the racks 55 are respectively located on opposite sides of the long hole 421.

The contact surface between the stopper 53 and the brake block 54 is a matching concave and convex surface.

The brake block 54 has a plurality of ratchet teeth 541 corresponding to the racks 55.

As shown in FIG. 1, 4, 5, 6, and 7, in the following use case of the workbench 200, when the positioning unit 50 is in the fixed state, the user rotates the turntable 52 to interlock the stop 53 with the brake. The contact faces between the blocks 54 are staggered (as shown in FIGS. 4 and 5), and the brake block 54 is abutted against the racks 55 by the stoppers 53 while the telescopic arms 42 are fixed to the fixed arms 41. The telescopic arm 42 is incapable of moving, and the adjustment seat 40 provides the rotating base 30 to be stably supported.

When the positioning unit 50 is in the active state, when the user rotates the turntable 52 to interlock the contact surface between the stop 42 and the brake block 54 (as shown in FIGS. 6 and 7), the brake block 54 Freely falling away from the racks 55, the telescopic arms 42 are slidable relative to the fixed arms 41, and the telescopic arms 42 are free to move and expand, thereby changing the length of the adjusting base 40.

Therefore, since the telescopic arm 42 can expand and contract in the front-rear direction X with respect to the fixed arm 41, the user can change the length of the adjustment seat 40 to change the length of the adjustment seat 40 to the user and the rotary seat. The angle and distance between the 30s are adjusted, so that the adjustment effect is fine, and the operation requirements of each user under different heights and different operating angles can be met.

More importantly, the rotating base 30 does not support the angle of inclination formed by the frictional force at the pivotal connection with the base 20, and the adjusting seat 40 can provide stable and inherent support on the back of the rotating base 30. When the rotating base 30 is mounted with a touch screen (not shown), even if the user's finger presses the touch screen from the front of the rotating base 30, the tilt angle of the touch screen is not changed, so The user does not need to frequently correct the tilt angle of the touch screen. As long as the tilt angle of the rotating base 30 is adjusted once, it can be used for a long time.

It is worth mentioning that the adjustment of the large angle is achieved by the cooperation of the adjusting seat 40 and the different ribs 22, and the fine adjustment of the small angle can be achieved by the telescopic arm 42.

In other embodiments, one end of the telescopic arm 42 can be pivotally connected to the pivots 31 through the structure of the two telescopic pins, or the telescopic arm 42 is made of plastic material and the end of the pivoting base 30 is convex.
