Description

Technical Field

[0001] This utility model relates to a limit switch based on laser welding technology, belonging to the field of limit switch technology. Background Technology

[0002] Limit switches operate primarily based on mechanically sensing the position of a moving object. When the object reaches a preset position, the limit switch outputs a signal, thereby controlling the mechanism to complete the corresponding action. Specifically, the main structure of a limit switch includes a spring plate, a movable plate, contacts, and a housing. Traditional limit switches are mostly screw-fixed assembly designs, which have limited airtightness and watertightness, making them unsuitable for special environments; the wiring of traditional limit switches is prone to bending; and the screws in the traditional limit switch roller structure are prone to loosening over long-term operation. Utility Model Content

[0003] The purpose of this invention is to provide a limit switch based on laser welding technology to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a limit switch based on laser welding process, comprising an upper housing, an anti-bending wiring bracket, a lower housing, a braking unit, an adjustable connecting rod, a roller, a mounting plate, and an anti-loosening upright. An anti-bending wiring bracket is provided at the rear end of the upper housing. The upper housing, lower housing, and braking unit are sealed and installed by laser welding process. The mounting plate positions the adjustable connecting rod at the braking unit position by screws and the anti-loosening upright. A roller is independently mounted on the top of the adjustable connecting rod.

[0005] Preferably, the anti-bending wiring bracket consists of a mounting bracket, a rear mounting ring, a shock-absorbing spring, and a front mounting ring. The rear mounting ring is positioned and welded onto the mounting bracket, and the rear mounting ring, the shock-absorbing spring, and the front mounting ring are assembled in sequence.

[0006] Preferably, the anti-loosening pole consists of a rubber pad, a support spring assembly, an upper pad, a mounting bolt, and an anti-loosening insert. The rubber pad, the support spring assembly, and the upper pad are assembled and installed in sequence by the mounting bolt, and the anti-loosening insert is horizontally installed at the through hole position of the mounting bolt.

[0007] Preferably, the bottom of the rubber pad is formed with anti-slip ridges.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The anti-bending connector bracket consists of a mounting bracket, a rear mounting ring, a shock-absorbing spring, and a front mounting ring. The connector passes through the frame of the anti-bending connector bracket. When the connector is pulled, the shock-absorbing springs of the front and rear mounting rings act as spring buffers to avoid excessive bending.

[0010] The anti-loosening upright consists of a rubber pad, a support spring assembly, an upper pad, mounting bolts, and an anti-loosening insert. When the braking unit drives the adjustable connecting rod in reciprocating motion for an extended period, the screws on the mounting plate may loosen. The anti-loosening upright is then screwed onto the threaded mounting plate. The mounting bolts of the anti-loosening upright are tightened to ensure proper contact with the adjustable connecting rod. At the upper end of the mounting plate, the rubber pad of the anti-loosening upright, in conjunction with the support spring, provides structural cushioning to prevent screw loosening. The anti-loosening insert further limits the position of the mounting bolts to prevent loosening. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, a limit switch based on laser welding technology includes an upper housing 1, an anti-bending wiring bracket 2, a lower housing 3, a braking unit 4, an adjustable connecting rod 5, a roller 6, a mounting plate 7, and an anti-loosening upright 8. The anti-bending wiring bracket 2 is provided at the rear end of the upper housing 1. The upper housing 1, the lower housing 3, and the braking unit 4 are installed by laser welding in a sealed manner. The mounting plate 7 positions the adjustable connecting rod 5 at the position of the braking unit 4 by screws and the anti-loosening upright 8. The roller 6 is independently mounted on the top of the adjustable connecting rod 5.

[0018] The anti-bending wiring bracket 2 consists of a mounting bracket 9, a rear mounting ring 10, a shock-absorbing spring 11, and a front mounting ring 12. The rear mounting ring 10 is positioned and welded to the mounting bracket 9. The rear mounting ring 10, the shock-absorbing spring 11, and the front mounting ring 12 are installed in sequence. The wiring passes through the frame of the anti-bending wiring bracket 2. When the wiring is pulled, the shock-absorbing spring 11 of the front and rear mounting rings acts as a spring buffer to avoid excessive bending.

[0019] The anti-loosening upright 8 consists of a rubber gasket 13, a support spring assembly 14, an upper gasket 15, a mounting bolt 16, and an anti-loosening insert 17. The rubber gasket 13, support spring assembly 14, and upper gasket 15 are assembled and installed in sequence using the mounting bolt 16. The anti-loosening insert 17 is horizontally installed at the through hole position of the mounting bolt 16. The anti-loosening upright 8 is screwed onto the mounting plate 7. The mounting bolt 16 of the anti-loosening upright 8 is contacted and tightened with the adjustable connecting rod 5. At the upper end of the mounting plate 7, the rubber gasket 13 of the anti-loosening upright 8, together with the support spring 14, acts as a structural buffer to prevent the screws from loosening. The anti-loosening insert 17 limits the position of the mounting bolt 16 to prevent loosening.

[0020] The bottom of the rubber pad 13 is formed with anti-slip ridges, which provides excellent anti-slip performance.

[0021] Specific usage: A limit switch based on laser welding technology. The upper and lower housings are laser welded, resulting in good airtightness and watertightness. The wiring passes through the anti-bending wiring bracket. When the wiring is pulled, the damping springs of the front and rear mounting rings act as spring buffers to avoid excessive bending. The braking unit drives the adjustable connecting rod to work back and forth for a long time. The screws of the mounting plate may loosen. The anti-loosening upright is screwed into the thread of the mounting plate. The mounting bolt of the anti-loosening upright is tightened in contact with the adjustable connecting rod. The rubber gasket of the anti-loosening upright at the upper end of the mounting plate, together with the support spring, acts as a structural buffer to prevent the screws from loosening. The anti-loosening plug limits the position of the mounting bolt to prevent loosening.

[0022] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
