Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example

[0025] Please refer to Figure 1-Figure 5 , which is a schematic diagram of the structure of the micro switch fixed position adjustment device in the embodiment of the utility model;

[0026] This embodiment provides a micro switch fixed position adjustment device, which is used to adjust the fixed position of the micro switch 50 during the assembly process of the unlocking switch 40, wherein the unlocking switch 40 is connected to the contact 53 of the micro switch 50 through the spring clip 51, including:

[0027] The base 10 is provided with a digital dial indicator 20 and a trigger fixing frame 30, the digital dial indicator 20 and the trigger fixing frame 30 are arranged opposite to each other, the unlocking switch 40 and the micro switch 50 are fixed on the side of the trigger fixing frame 30 close to the digital dial indicator 20, and the telescopic end of the unlocking switch 40 is opposite to the measuring rod of the digital dial indicator 20; a threaded screw-in mechanism 60 is provided on the side of the trigger fixing frame 30 away from the digital dial indicator 20, the trigger fixing frame 30 is provided with a screw-in hole 31, and the threaded screw-in mechanism 60 and the plunger 42 of the unlocking switch 40 are respectively located at the two ends of the screw-in hole 31.

[0028] Next, the micro switch fixed position adjustment device of this exemplary embodiment will be further described.

[0029] It should be noted that during the assembly of the unlocking switch 40, the micro switch 50 needs to be adjusted to a suitable fixed position to ensure that the micro switch 50 can output an unlocking signal when the plunger 42 of the unlocking switch 40 moves into place. However, the prior art cannot accurately measure the relationship between the fixed position of the micro switch 50 and the movement stroke of the plunger 42, and cannot meet the assembly requirements.

[0030] In some embodiments of the present application, the base 10 is provided with a digital dial indicator 20 and a trigger fixing frame 30, the digital dial indicator 20 and the trigger fixing frame 30 are arranged opposite to each other, the unlocking switch 40 and the micro switch 50 are fixed on the side of the trigger fixing frame 30 close to the digital dial indicator 20, and the telescopic end of the unlocking switch 40 is opposite to the measuring rod of the digital dial indicator 20, and the displacement of the unlocking switch 40 can be measured by the digital dial indicator 20; a threaded screw-in mechanism 60 is provided on the side of the trigger fixing frame 30 away from the digital dial indicator 20, and the trigger fixing frame 30 is provided with a screw-in hole 31, and the threaded screw-in mechanism 60 and the plunger 42 of the unlocking switch 40 are respectively located at the two ends of the screw-in hole 31. The threaded screwing mechanism 60 is used to push the plunger 42 to move, thereby pushing the cone 45 to move. The stroke of the cone 45 is measured by the digital dial indicator 20 to be 2mm to 2.5mm (the stroke of the plunger 42 is consistent with the stroke of the cone 45). The position of the microswitch 50 is adjusted until the microswitch 50 outputs an unlocking signal measured by a multimeter to fix the position of the microswitch 50.

[0031] It should be noted that the micro switch 50 is installed on the upper part of the housing of the unlocking switch 40 through a spring clip 51. One end of the spring clip 51 is sleeved on the outside of the micro switch 50. The spring clip 51 has a position adjustment hole and is fixed to the micro switch 50 through a locking member 52. The other end of the spring clip 51 is located between the unlocking switch 40 and the micro switch 50, so that the unlocking switch 40 pushes the contact 53 of the micro switch 50 to move through the spring clip 51. Through the above structure, the movement of the unlocking switch 40 can push the spring clip 51 to move. The spring clip 51 is arranged between the micro switch 50 and the unlocking switch 40, so that the contact 53 of the micro switch 50 can be pushed to move, triggering the micro switch 50. After adjusting to a suitable position, the spring clip 51 is locked and fixed to the micro switch through the locking member 52. The locking member 52 can be a screw of M2×10. After adjusting to a suitable position, the screw can be locked to fix it; after the unlocking switch 40 is reset, the spring clip 51 is also reset under its elastic action.

[0032] When unlocking, the plunger 42 moves to the left under the action of the threaded screwing mechanism 60, pushing the cone 45 of the unlocking switch 40 to move to the left, and the cone 45 pushes the spring clip 51 to deform, and the spring clip 51 pushes the contact 53 of the micro switch 50 to move upward, so that the contact 53 inside the micro switch 50 contacts, and the unlocking signal is output through the wire. In order to ensure that the assembly requirement of the unlocking switch 40 is that the plunger 42 moves 2mm to 2.5mm to the left, the above position adjustment hole is designed as a waist-shaped hole 514, the length of the waist-shaped hole 514 is 4mm, the width is 2mm, and a 2mm adjustment margin is reserved. Figure 5 .

[0033] As a preferred embodiment, the threaded screwing mechanism 60 includes a screw 61 and a screw sleeve 62. The screw sleeve 62 and the unlocking switch 40 are respectively fixed to the two sides of the trigger fixing frame 30 by M4×35 screws. One end of the screw 61 is inserted into the screw sleeve 62 and is threadedly connected to the screw sleeve 62. A through hole connected to the screw-in hole 31 is provided in the screw sleeve 62, and the screw 61 can move in the through hole. By rotating the screw 61, it is slowly fed into the through hole under the action of the screw, so that it can push the plunger 42 at the other end of the through hole to move. Screwing in by thread can slow down the screwing speed, improve the screwing accuracy, and enable the moving distance to meet the assembly requirements.

[0034] As a preferred embodiment, the thread screwing mechanism 60 further includes a rotating handle 63 , which is connected to the end of the screw rod 61 . The rotating handle 63 is easy to operate and saves effort.

[0035] As a preferred embodiment, a movable shaft 64 and a stopper 65 are provided in the through hole. The stopper 65 is located at one end of the through hole connected to the screw-in hole 31. One end of the movable shaft 64 is fixedly connected to the end of the screw rod 61. The other end of the movable shaft 64 is slidably penetrated through the stopper 65. An elastic member 66 is provided on the outer sleeve of the movable shaft 64. The elastic member 66 abuts against the stopper 65. The elastic member 66 is a spring. Since the distance range required for assembly is 2 mm to 2.5 mm, an elastic structure is provided in the through hole, and the elastic force of the spring is used to suppress the feeding of the screw rod 61, so as to prevent the screw rod 61 from rotating excessively beyond the distance range required for assembly.

[0036] As a preferred embodiment, the digital dial gauge 20 is connected to the magnetic meter base 22 through the meter frame connecting rod 21, the base 10 is a magnetic conductive material, and the magnetic meter base 22 is magnetically attracted to the base 10. The digital dial gauge 20 is fixed to the base 10 by magnetic attraction. When the position of the micro switch 50 is adjusted to a suitable position and fixed, the digital dial gauge 20 can be removed and reused, which is convenient for installation and disassembly.

[0037] The working principle of the embodiment of the present application is as follows: Turn the handle to make the screw 61 press against the plunger 42 and move 2mm to 2.5mm to the left, use the digital dial gauge 20 to measure the stroke of the cone 45 to be 2mm to 2.5mm (the stroke of the plunger 42 is consistent with the stroke of the cone 45), adjust the position of the micro switch 50 until the micro switch 50 outputs an unlocking signal measured by the multimeter, and then tighten the micro switch 50 fixing screw M2×10 to fix the position of the micro switch 50. The device has a simple structure, high reliability, simple operation, and low cost, and can accurately adjust the position of the micro switch 50, ensuring that the micro switch 50 can output an unlocking signal when the plunger 42 moves into place, ensuring the assembly quality of the unlocking switch 40, and saving adjustment time.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
