Technical Field

[0001] This utility model relates to the field of test bracket technology, specifically an adjustable test bracket. Background Technology

[0002] An adjustable test stand is a device used to support and fix test equipment or the object under test. It has multiple adjustment functions such as height, angle, and position to adapt to different test needs and environments.

[0003] Chinese patent CN221199753U discloses an adjustable test stand, comprising a mounting plate, a placement plate fixedly connected to the top of the mounting plate, a fixing component on the top of the placement plate, a fixing post rotatably mounted on the outer side of the mounting plate, a fixing seat slidably mounted on the outer side of the fixing post, a base plate fixedly connected to the bottom of the fixing seat, and a fixing component including fixing blocks on both sides of the top of the placement plate, a connecting block on the top of the fixing blocks, and a limit block fixedly connected to the bottom of the connecting blocks. This adjustable test stand solves the problem that existing circuit boards require frequent insertion and removal during testing, and with many electronic components, the lack of clamps to fix the circuit boards makes operation inconvenient during insertion and removal, and also makes it difficult to adjust the angle and height, causing inconvenience to operators.

[0004] The aforementioned bracket is convenient for adjusting the angle and height, but it requires the use of both hands to adjust it during use, and its stability cannot be guaranteed after adjustment. Therefore, an adjustable test bracket is needed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable test stand to solve the problem that existing stands require two hands to adjust during use, and the stability cannot be guaranteed after adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable test bracket, including a fixed plate, on which a lifting mechanism is provided; the lifting mechanism includes a base support and a top support, the base support is fixedly installed on the upper side of the fixed plate, and sliding grooves are provided on both sides of the base support and the top support, and a first support is rotatably installed between the base support and the top support, and a second support is slidably installed between the upper and lower sliding grooves, a connecting frame is rotatably installed on the lower side of the second support, and an adjusting bolt is rotatably installed on the connecting frame.

[0007] Preferably, the bottom support and the top support are relatively parallel, and the two sliding grooves are located at opposite positions on the bottom support and the top support, respectively.

[0008] Preferably, the first support and the second support have the same length, and the first support and the second support are connected by a central rotatable connection.

[0009] Preferably, one end of the adjusting bolt is located in the middle of the connecting frame, and the adjusting bolt is threaded onto the base.

[0010] Preferably, the top support is provided with a rotating mechanism, which includes two limiting seats and a rotating seat. The two limiting seats are fixedly installed on the upper side of the top support, and a positioning bolt is threaded through one of the limiting seats. A protective frame is fixedly installed on the limiting seat. The rotating seat has several positioning teeth on its outer side, and a slide is fixedly installed on the upper side of the rotating seat. Two clamps are slidably installed inside the slide, and a support spring is fixedly installed between the two clamps and the slide.

[0011] Preferably, the rotating base is rotatably mounted between two limiting seats, and the positioning bolt is adapted to a plurality of positioning teeth.

[0012] Preferably, the two clamps are slidably mounted on the slide in opposite directions, and the two clamps are slidably connected in an alternating manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The adjustable test bracket moves within the base by pushing and pulling the connecting frame with the adjusting bolt. During this movement, one end of the second support frame moves within the base. Because the second support frame and the first support frame are connected by a central rotation, the first support frame rotates and supports the top support to move up and down relative to the base. Therefore, the test sample can be raised and lowered by adjusting the adjusting bolt, achieving the effect of single-handed operation.

[0014] 2) This adjustable test bracket controls the movement of the positioning bolt within the limit seat, keeping it in close contact with and separating from the positioning teeth. When the positioning bolt rotates and is in close contact with the positioning teeth, the rotating seat will be restricted and unable to rotate. When the positioning bolt disengages from the positioning teeth, the direction of the test item can be changed by rotating the rotating seat. The two clamps are slidably mounted on the slide in opposite directions and are connected in an alternating manner. In use, simply reverse the movement of the two clamps to increase the clamping space. After placing the test item between the two clamps, release the clamps to clamp the item under the action of the support spring. The bracket is convenient to operate while ensuring its stability.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Combination Figures 1-3 An adjustable test bracket includes a fixed plate 1, on which a lifting mechanism 2 is provided. The lifting mechanism 2 includes a base support 201 and a top support 202. The base support 201 is fixedly installed on the upper side of the fixed plate 1, and both sides of the base support 201 and the top support 202 are provided with sliding grooves 203. A first support 204 is rotatably installed between the base support 201 and the top support 202. A second support 205 is slidably installed between the upper and lower sliding grooves 203. A connecting frame 206 is rotatably installed on the lower side of the second support 205, and an adjusting bolt 207 is rotatably installed on the connecting frame 206.

[0019] The base 201 and top 202 are parallel to each other, ensuring that the top 202 stably supports the item. Two sliding grooves 203 are located at opposite positions on the base 201 and top 202, facilitating the connection of the second support 205. The first support 204 and the second support 205 are of the same length, and both the first support 204 and the second support 205 are connected by a central rotation. One end of the adjusting bolt 207 is located in the middle of the connecting frame 206, and the adjusting bolt 207 is threaded onto the base 201. In use, by controlling the adjusting bolt 207 to push and pull the connecting frame 206, it moves within the base 201. During its movement, one end of the second support 205 moves within the base 201. Benefiting from the central rotation connection between the second support 205 and the first support 204, the first support 204 rotates and supports the top 202 to move up and down relative to the base 201. Therefore, by adjusting the adjusting bolt 207, the test item can be raised and lowered, achieving the effect of single-handed operation. Example

[0020] See Figure 4 and Figure 5 A rotating mechanism 3 is provided on the top support 202. The rotating mechanism 3 includes two limit seats 301 and a rotating seat 302. The two limit seats 301 are fixedly installed on the upper side of the top support 202, and a positioning bolt 303 is threaded through one of the limit seats 301. A guard 304 is fixedly installed on the limit seat 301. Several positioning teeth 305 are opened on the outside of the rotating seat 302. A slide 306 is fixedly installed on the upper side of the rotating seat 302. Two clamps 307 are slidably installed inside the slide 306. A support spring 308 is fixedly installed between the two clamps 307 and the slide 306.

[0021] The rotating base 302 is rotatably mounted between two limiting seats 301. The positioning bolt 303 is adapted to several positioning teeth 305. The two clamping seats 307 are slidably mounted on the slide 306 in opposite directions, and the two clamping seats 307 are alternately slidably connected. In use, by controlling the movement of the positioning bolt 303 within the limiting seat 301, it is kept in close contact with and separated from the positioning teeth 305. When the positioning bolt 303 rotates and is in close contact with the positioning teeth 305, the rotating base 302 will be restricted and cannot rotate. When the positioning bolt 303 is disengaged from the positioning teeth 305, the direction of the item to be tested can be changed by rotating the rotating base 302. The two clamping seats 307 are slidably mounted on the slide 306 in opposite directions and are alternately slidably connected. In use, the clamping space can be increased by simply moving the two clamping seats 307 in the opposite direction. After the item to be tested is placed between the two clamping seats 307, the clamping seats 307 are released, and the item is clamped under the action of the support spring 308.

[0022] In actual operation, by controlling the adjusting bolt 207 to push and pull the connecting frame 206 to move it within the base 201, one end of the second support 205 will move within the base 201 during its movement. Benefiting from the fact that the second support 205 and the first support 204 are connected by a central rotation, the first support 204 will rotate and support the top support 202 to move up and down relative to the base 201. Therefore, by adjusting the adjusting bolt 207, the test sample can be raised and lowered, achieving the effect of single-handed operation. By controlling the movement of the positioning bolt 303 within the limiting seat 301, it is kept in close contact with and separated from the positioning teeth 305. When the positioning bolt 303 rotates and is in close contact with the positioning teeth 305, the rotating seat 302 will be restricted and unable to rotate. When the positioning bolt 303 is disengaged from the positioning teeth 305, the direction of the item to be tested can be changed by rotating the rotating seat 302. The two clamps 307 are slidably mounted on the slide 306 in opposite directions and are connected in an alternating manner. In use, the clamping space can be increased by simply moving the two clamps 307 in the opposite direction. After the item to be tested is placed between the two clamps 307, the clamps 307 can be released to clamp the item under the action of the support spring 308.
