Description

Technical Field

[0001] The utility model belongs to the technical field of detection brackets, and in particular relates to a pressure sensor detection bracket. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. It is usually composed of a pressure sensitive element and a signal processing unit. The working principle of the pressure sensor is usually based on the principle of resistance or capacitance change. The resistance pressure sensor measures pressure by measuring the deformation of an elastic metal film. When external pressure is applied, the film will deform, causing the resistance on its surface to change. The capacitive pressure sensor senses pressure by measuring capacitance changes. When the pressure changes, the capacitance of the capacitor will also change accordingly. After the pressure sensor is produced, in order to ensure the quality of the pressure sensor, it may be necessary to test the pressure sensor. During the test, in order to facilitate the support of the pressure sensor, a bracket may be used to support the pressure sensor. Therefore, it can be seen that the existing detection brackets basically meet people's practical needs, but the following problems still exist.

[0003] However, when installing a pressure sensor on a general bracket, the pressure sensor may be installed through a threaded connection. During the installation process, the operator may turn the bolts to install the pressure sensor on the bracket. However, since the operator may turn the pressure sensor for a long time, the threads on the bracket used for threaded connection of the pressure sensor may slip, which may cause the bracket to be unable to be used normally. For this reason, we propose a pressure sensor detection bracket. Utility Model Content

[0004] The utility model provides a pressure sensor detection bracket. After the operator turns the turning handle, the turning handle meshes with the worm gear through the worm, so that the worm gear pulls the connecting rod to move through the turntable, and the connecting rod drives the clamping block to move through the pulling block, so that the clamping block clamps the pressure sensor placed on the detection bracket, fixes the pressure sensor on the detection bracket, thereby supporting the pressure sensor, making it convenient for the operator to support the pressure sensor when detecting it, and improving the convenience of the operator in supporting the pressure sensor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure sensor detection bracket, comprising a detection frame, a pad block is fixed in the middle of the detection frame, and a worm wheel is fitted on the surface of the pad block, a worm is meshed at the end of the worm wheel, and a rotating rod is fixed to the end of the worm, a turning handle is fixed to the end of the rotating rod, a turntable is fixed on the surface of the worm wheel, and pull plates are symmetrically fixed on both sides of the turntable, the end of the pull plate is rotatably connected to a connecting rod, and the end of the connecting rod is rotatably connected to a pulling block, and a clamping block fitted on the surface of the detection frame is fixed on the surface of the pulling block.

[0010] Furthermore, the surfaces of the rotating rod and the worm are both sleeved with support frames, and the support frames are both fixed on the detection frame. The end of one side of the rotating rod that passes through the detection frame is sleeved with a ring fixed on the inner wall of the detection frame.

[0013] The beneficial effects of the utility model are:

[0014] 1. The pressure sensor detection bracket is provided with a turning handle, a worm, a worm wheel, a turntable, a connecting rod, a pulling block and a clamping block. When the operator turns the turning handle, the turning handle drives the worm and the worm wheel to engage with each other, so that the worm wheel drives the turntable to rotate, and when the turntable rotates, the turntable pulls the pulling block to move through the connecting rod, and the pulling block pulls the clamping block to move, so that the clamping block clamps the pressure sensor placed on the detection frame, thereby installing the pressure sensor on the detection frame. The operator is no longer required to install the pressure sensor by threaded connection, thereby improving the convenience of the pressure sensor installed by the operator.

When the clamping block is clamped on the surface of the pressure sensor, the clamping block drives the limit rod to move through the spring groove, so that the limit rod and the surface of the pressure sensor fit each other, and when the clamping block continues to move, the clamping block drives the spring groove to move on the surface of the limit rod, so that the limit rod enters the spring groove, and the limit rod avoids the pressure sensor. Since other limit rods are not restricted by the pressure sensor, other limit rods are arranged around the pressure sensor, so that other limit rods restrict the pressure sensor, thereby avoiding the pressure sensor from moving randomly during the clamping process, thereby improving the stability of the pressure sensor detection.

A clamping block 13 that fits on the surface of the detection frame 1 is welded on the surface of the pull block 10. When the operator needs to support the pressure sensor, the operator first holds the hand on the surface of the turning handle 30, and then the operator turns the turning handle 30, and the turning handle 30 drives the turning rod 28 to rotate. When the turning rod 28 rotates, the turning rod 28 drives the worm 6 to rotate, so that the worm 6 The worm wheel 4 is meshed with the worm wheel 4 to rotate the worm wheel 4, and after the worm wheel 4 rotates, the worm wheel 4 drives the rotating disk 18 to rotate. When the rotating disk 18 rotates, the rotating disk 18 drives the pull plate 16 to move, and the pull plate 16 drives the second rotating shaft 24 to move through the second avoidance groove 25, and the second rotating shaft 24 drives the connecting rod 19 to move. When the second rotating shaft 24 drives the connecting rod 19 to move, the cylindrical circular through hole provided on the end of the connecting rod 19 rotates on the surface of the second rotating shaft 24, so that the connection between the connecting rod 19 and the pull plate 16 is The gap is adjusted, and when the connecting rod 19 moves, the connecting rod 19 drives the first avoidance groove 23 to move through the first rotating shaft 22, so that the first avoidance groove 23 drives the pull block 10 to move, and the pull block 10 drives the clamping block 13 to move, so that the two groups of clamping blocks 13 are close to each other, and the clamping blocks 13 clamp the pressure sensor, so that the two groups of clamping blocks 13 clamp the pressure sensor, which is convenient for the operator to fix the pressure sensor, and the operator is no longer required to install the pressure sensor by threaded connection, thereby improving the convenience of the pressure sensor installed by the operator.

[0029] In other embodiments, a plurality of groups of spring grooves 12 are provided in the middle of the clamping block 13, and the spring grooves 12 are all embedded with fixed blocks 21, and a plurality of groups of limiting rods 15 penetrating the spring grooves 12 are welded on the surface of the fixed block 21, and a sleeve 20 is provided in the middle of the limiting rod 15 and the fixed block 21, and a sleeve rod 11 welded on the inner wall of the spring groove 12 is inserted in the middle of the sleeve 20, and the sleeve rod 11 is set to a cylindrical shape, and the sleeve 20 is set to a cylindrical groove, and the cylindrical groove set in the sleeve 20 matches the cylindrical shape set in the sleeve rod 11, and the surface of the sleeve rod 11 is wound with springs 14 respectively abutting between the surface of the fixed block 21 and the inner wall of the spring groove 12, when the clamping block 13 drives the fixed block 21 to move through the spring groove 12, the fixed block 21 drives the limiting rod 15 to fit with the pressure sensor, and when the clamping block 13 continues to move, the clamping block 13 drives the spring groove 12 on the surface of the fixed block 21 The spring 14 is pressed against the piston 21 and the piston 22 is moved, and the limit rod 15 enters the spring groove 12. During the movement of the spring groove 12, the spring groove 12 drives the sleeve rod 11 to move, so that the sleeve rod 11 moves in the sleeve tube 20, and the sleeve tube 20 avoids the sleeve rod 11. During the movement of the spring groove 12, the gap between the inside of the spring groove 12 and the surface of the fixed block 21 becomes smaller, so that the spring groove 12 and the fixed block 21 squeeze the spring 14. After the spring 14 is elastically deformed, the limit rod 15 enters the spring groove 12. Since the limit rods 15 at other positions do not contact the pressure sensor, the other limit rods 15 do not enter the spring groove 12. The other limit rods 15 are blocked on the surface of the pressure sensor, so that the other limit rods 15 limit the pressure sensor, thereby avoiding the pressure sensor from moving at will during the clamping process, thereby improving the stability of the pressure sensor detection.

[0030] In other embodiments, a rotating sleeve 3 is opened in the middle of the worm wheel 4 and the turntable 18, and a rotating block 17 is inserted in the middle of the rotating sleeve 3, and the rotating block 17 is respectively welded to the inner wall of the detection frame 1 and the surface of the pad 2. When the worm wheel 4 and the turntable 18 are rotating, the rotating sleeve 3 opened in the middle of the worm wheel 4 and the turntable 18 rotate on the surface of the rotating block 17, and the turntable 18 and the worm wheel 4 are restricted by the rotating sleeve 3 and the rotating block 17 to prevent the turntable 18 and the worm wheel 4 from shaking left and right when they are rotating, thereby ensuring the stability of the rotation of the turntable 18 and the worm wheel 4.

[0031] In other embodiments, a plurality of groups of ball grooves 27 are provided around the cushion block 2, and a ball 26 is embedded in the middle of the ball grooves 27. The surface of the ball 26 is provided with a guide groove 29 provided on the worm gear 4. When the worm gear 4 rotates, the worm gear 4 drives the guide groove 29 to move.

The end of the rotating rod 28 passing through the detection frame 1 is sleeved with a ring 31 welded on the inner wall of the detection frame 1. The support frame 5 is sleeved on the rotating rod 28 and the worm 6, and the support frame 5 is fixed on the inner wall of the detection frame 1, so that the support frame 5 supports the worm 6 and the rotating rod 28, thereby improving the stability of the worm 6 and the rotating rod 28 during rotation. In addition, since the end of the rotating rod 28 passing through the detection frame 1 is sleeved with a ring 31 fixed on the inner wall of the detection frame 1, the ring 31 increases the contact area between the rotating rod 28 and the detection frame 1, thereby improving the stability of the rotation of the rotating rod 28.

[0033] In other embodiments, support blocks 8 are symmetrically welded to the inner walls on both sides of the detection frame 1, and a traction groove 7 is opened in the middle of the support block 8, and a traction block 9 welded on the pulling block 10 is inserted in the middle of the traction groove 7. When the pulling block 10 moves, the pulling block 10 pulls the traction block 9 to slide in the traction groove 7. By sliding the traction block 9 in the traction groove 7, the traction block 9 and the traction groove 7 pull the pulling block 10, thereby improving the stability of the movement of the pulling block 10 and preventing the pulling block 10 from shaking back and forth when the pulling block 10 moves.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
