Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a lifting induction switch detection device. Background Art

[0002] As an advanced automation control component, the lift sensor switch includes pressure sensing, infrared sensing, electromagnetic induction, etc. The pressure sensor is an intelligent control device that controls the lifting behavior of equipment by detecting pressure changes, that is, the pressure-sensitive lift sensor switch. It is widely used in modern industrial automation, medical equipment, smart home, automotive electronics and other fields.

[0003] The pressure-sensitive lifting induction switches currently on the market usually need to be tested after production, and the current detection device usually sets up a control circuit, connects the pressure-sensitive lifting induction switch to the control circuit, and presses the pressure-sensitive lifting induction switch to see if the indicator light in the control circuit can be triggered. However, the pressure-sensitive lifting induction switch sometimes fails not because of open circuit or short circuit, but because of abnormal components in the pressure-sensitive lifting induction switch, resulting in high resistance. At this time, it cannot be detected by a simple indicator light test. When this pressure-sensitive lifting induction switch is used, it will cause the driven lifting mechanism to move very slowly. Utility Model Content

A metal sheet is provided on the inner side of the L-shaped block, and the metal sheet is connected to the control circuit; magnets are provided on the tops of the two L-shaped blocks, and the magnetic poles of the tops of the two magnets are opposite.

[0010] Furthermore, a protruding groove is provided at the quick-release interface of the bottom plate, the two L-shaped blocks are hinged on both sides of the protruding groove respectively, a top block is provided at the bottom center of the protruding groove, and a compression spring is provided at the lower side of the top block.

[0020] Furthermore, the power supply is directly connected to a positive-negative conversion switch, which includes two groups of normally open ports and two groups of normally closed ports. One group of normally open ports and normally closed ports are connected to the positive pole of the power supply and a quick release interface, and the other group of normally open ports and normally closed ports are connected to the negative pole of the power supply and the electric push rod.

DETAILED DESCRIPTION

[0030] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Example 1

[0032] like Figure 1-2 The lifting induction switch detection device shown includes a base plate 100 and an electric push rod 200 arranged on the base plate 100, a control circuit 300 and two fast-release interfaces 400, wherein the control circuit 300 connects the electric push rod 200 and the two fast-release interfaces 400, the fast-release interfaces 400 are connected to the lifting induction switch, and the control circuit 300 is connected to a power supply 310 to form a complete closed circuit.

[0033] like Figure 3-4As shown, the fast-play interface 400 includes two symmetrically arranged L-shaped blocks 410. A protruding groove 110 is provided at the bottom plate 100 where the fast-play interface 400 is provided. The two L-shaped blocks 410 are respectively hinged on both sides of the protruding groove 110, and a torsion spring 411 is provided at the hinge to ensure that they can rebound to the original state; a metal sheet 412 is provided on the inner side of the L-shaped block 410, and the metal sheet 412 is connected to the control circuit 300 to ensure that the fast-play interface 400 can accurately connect the control circuit 300 and the lifting induction switch; magnets 413 are provided on the top of the two L-shaped blocks 410, and the magnetic poles of the tops of the two magnets 413 are opposite. When in Figure 4 In the state, the two magnets 413 will attract each other to ensure that the metal sheet 412 is in close contact with the joint of the lifting sensor switch.

[0034] like Figure 3-4 As shown, a top block 111 is provided at the bottom center of the raised groove 110, and a compression spring 112 is provided on the lower side of the top block 111. The top block 111 supports the joint of the lifting sensor switch to ensure that it is tightly attached to the metal sheet 412. It should be noted that the position of the top block 111 will not interfere with the rotation of the L-shaped block 410.

[0035] like Figure 1 As shown, the bottom plate 100 is provided with a fixing mechanism located on one side of the fast-release interface 400. The fixing mechanism is two elastic sheets 120. The elastic sheets 120 clamp the lifting sensor switch to fix the lifting sensor switch to prevent the lifting sensor switch from accidentally moving during detection so that its connector is pulled away from the fast-release interface 400.

[0036] like Figure 1 , 5 As shown, an L-shaped groove 130 is provided on the bottom plate 100, and one end of the elastic sheet 120 is set as an L-shaped structure 121.

[0037] like Figure 2 As shown, the control circuit 300 is:

[0038] The positive pole of the power supply 310 is connected to a fast-release interface 400, and the other fast-release interface 400 is connected to the electric push rod 200, and the electric push rod 200 is connected to the negative pole of the power supply 310, thereby forming a complete circuit, and the start and stop of the electric push rod 200 can be controlled by the lifting induction switch.

[0039] like Figure 2 As shown, both ends of the electric push rod 200 are connected in parallel with a connection indicator light 320. When the electric push rod 200 does not move but the indicator light 320 is on, it indicates that there is a connection, but the resistance is too large and the electric push rod 200 cannot be started; when the electric push rod 200 does not move and the indicator light 320 is not on, it indicates that the circuit is broken.

[0040] like Figure 2 As shown, a fuse 330 is provided between the electric push rod 200 and the connected quick-release interface 400 to protect the electric push rod 200 .

[0041] Example 2

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
