Anti-loosening signal lamp with threaded mask

Abstract

The invention discloses a threaded mask anti-loosening signal lamp which comprises a transparent mask and a shell, a circle of mask anti-retreating teeth are arranged at the bottom of the transparent mask around the axis of the transparent mask, shell anti-retreating teeth are correspondingly arranged in the shell, and the sections of the mask anti-retreating teeth and the shell anti-retreating teeth are asymmetrically designed. The transparent face cover and the shell are respectively provided with a slope face for guiding screwing-in and a blocking face for stopping return, the transparent face cover is connected with the shell through threads, and the blocking faces of the face cover anti-retreating teeth abut against the blocking faces of the shell anti-retreating teeth. The mechanical one-way non-return mechanism is formed after the threads are screwed in place through meshing matching of the mask anti-retreating teeth at the bottom of the transparent mask and the shell anti-retreating teeth at the bottom of the shell inner ring. The mechanism allows the mask to be smoothly screwed in during installation, but can effectively resist reverse rotation loosening force caused by high-frequency vibration of equipment, thereby fundamentally solving the problem of loosening of the signal lamp mask in a vibration environment.

[0002] At present, the working environment of mechanical equipment often has oil stains, dust and the like, and the installed signal lamp needs to have certain waterproof performance, so the signal lamp usually adopts a threaded cover structure to prevent dirt. The existing threaded cover signal lamp often lacks effective anti-loosening structure, and the threaded cover is prone to loosening due to vibration in a high-frequency vibration environment, which is insufficient in reliability in the high-frequency vibration environment and affects the normal operation of the equipment. SUMMARY

[0003] The present application provides a threaded cover anti-loosening signal lamp to solve the problem that the threaded cover of the existing signal lamp is prone to loosening in a high-frequency vibration environment.

A metal lead sheet is arranged in the shell, the metal lead sheet is provided with a sawtooth structure, the sawtooth structure cooperates with the inner groove of the shell, and the metal lead sheet is fixed with the shell through a gasket screw. The signal lamp further comprises a light-emitting lamp plate, the pin of the light-emitting lamp plate is bent and welded after passing through the shell and the metal lead sheet. The signal lamp further comprises a rear cover, a rubber gasket and a fastening ring, and the rear cover, the rubber gasket and the fastening ring are installed on the rear side of the shell.

[0005] The signal lamp further comprises a waterproof O-shaped ring, and the waterproof O-shaped ring is arranged in the groove of the transparent cover.

[0006] The signal lamp further comprises a frosted cover, and the frosted cover is embedded in the inside of the transparent cover.

[0007] The assembly process of the threaded cover anti-loosening signal lamp is as follows: 1) The frosted cover is embedded in the transparent cover to form a front cover assembly; 2) The waterproof O-shaped ring is sleeved in the groove of the transparent cover; 3) The lead sheet is assembled with a gasket screw and then inserted into the inside of the shell, and the sawtooth structure cooperates with the groove of the shell to prevent back-off; 4) Put the pin of the light-emitting lamp plate through the hole of the shell and the lead sheet, bend it and then weld it to fix; 5) Install the back cover and rubber gasket on the back side of the shell; 6) Insert the assembled signal lamp into the installation hole of the equipment panel, and lock it from the back with the bevel fastening ring.

[0008] Compared with the prior art, the beneficial effects of the patent are: The meshing cooperation of the mask anti-back tooth at the bottom of the transparent mask and the shell anti-back tooth at the bottom of the inner ring of the shell forms a mechanical one-way reverse mechanism after the screw is screwed in place. The mechanism allows the mask to be smoothly screwed in during installation, but can effectively resist the reverse rotation loosening force caused by high-frequency vibration of the equipment, and fundamentally solves the problem of loosening of the signal lamp mask in a vibration environment. At the same time, combined with the waterproof O-ring and sealing structure, IP65 waterproof level is achieved, and the reliability and applicability of the signal lamp in a high-frequency vibration environment are improved.

Detailed Implementation

[0019] like Figures 1 to 9 As shown, the threaded face mask anti-loosening signal light provided by the present invention includes a transparent face mask 1 and a housing 5. The bottom of the transparent face mask 1 is provided with a ring of anti-loosening teeth 101 around its axis. Correspondingly, the housing 5 is provided with housing anti-loosening teeth 501. Both the face mask anti-loosening teeth 101 and the housing anti-loosening teeth 501 have asymmetrical cross-sections, each having a ramp surface 11 for guiding screwing in and a blocking surface 12 for preventing reverse loosening. The transparent face mask 1 and the housing 5 are connected by threads, causing the blocking surfaces 12 of the face mask anti-loosening teeth 101 and the housing anti-loosening teeth 501 to abut against each other, thereby preventing the transparent face mask 1 from loosening in the reverse direction.

[0020] The signal light also includes a waterproof O-ring 2, which is located in the groove of the transparent face shield 1 and is sealed by threaded compression.

[0021] The housing 5 is provided with a metal lead sheet 6, which has a serrated structure. The serrated structure cooperates with the inner groove of the housing 5 and is fixed to the housing 5 with a washer screw 7 to prevent it from falling out.

[0022] The signal light also includes a frosted cover 3, which is embedded inside the transparent mask 1.

[0023] The signal light also includes a light-emitting board 4, whose pins pass through the housing 5 and the metal lead sheet 6 and are then bent and welded.

[0024] The signal light also includes a rear cover 8, a rubber gasket 9, and a fastening ring 10. The rear cover 8, the rubber gasket 9, and the fastening ring 10 are installed on the rear side of the housing 5 for overall installation and fixation.

[0025] The installation method for this type of threaded face shield anti-loosening indicator light is as follows: 1) The frosted cover 3 is embedded into the transparent face mask 1 to form a front cover assembly; 2) Insert the waterproof O-ring 2 into the groove of the transparent face mask 1; 3) After assembling the lead wire piece 6 and the washer screw 7, insert it into the housing 5. The serrated structure cooperates with the groove of the housing to prevent it from falling out. 4) Pass the pins of the light board 4 through the holes in the housing 5 and the lead wire 6, bend them, and then weld them in place; 5) Install the rear cover 8 and rubber gasket 9 on the rear side of the housing 5; 6) Insert the assembled signal light into the mounting hole on the equipment panel and tighten it from the back using the toothed fastening ring 10.

[0026] The teeth profile of the transparent mask bottom's mask anti-back tooth and the shell inner ring's shell anti-back tooth are both asymmetrically designed, containing a guiding rotation-inclined slope and a reverse vertical surface for locking. When the transparent mask is rotated in, the inclined slope of the teeth is in contact and sliding. After being rotated, the reverse vertical surfaces of the teeth are in contact and abutting. When the reverse torque is generated by vibration, the vertical surfaces provide rigid resistance, thus realizing anti-back. This mechanism allows the mask to be smoothly rotated in during installation, but can effectively resist the reverse rotation loosening force caused by high-frequency vibration of the equipment, thus fundamentally solving the problem of signal lamp mask loosening in the vibration environment.

[0027] In addition: It should be noted that the above specific embodiments are only one optimization scheme of the patent, and any changes or improvements made by those skilled in the art based on the above concept are within the protection scope of the patent.
