Description

Technical Field

[0001] This utility model belongs to the technical field of anti-slip pipe joints, specifically an anti-slip pipe joint for traffic signal lights. Background Technology

[0002] In traffic signal facilities, for aesthetic and safety reasons, concealed wiring is often chosen during installation. The wiring runs along the internal channels of the pole, with holes drilled at the installation location to lead the wiring to the traffic signal device. However, traffic lights have a large light box structure, making direct installation on horizontally arranged poles inconvenient. They are often installed by extending branch pipes at the end of the branch pipes, or directly at the end of the horizontal pole. Application number 202320823520.7 discloses an anti-slip pipe connector for traffic lights, which allows for installation of traffic lights at bends. Anti-slip teeth are provided on the end face of the traffic light. These teeth, along with a plug, press the traffic light's installation position firmly between the plug and the bend of the anti-slip teeth. The anti-slip teeth constrain the rotation of the traffic light housing, thus preventing loosening of the connection between the traffic light and the external support structure, improving connection stability, and eliminating safety hazards. The plug installation requires tightening from inside the traffic light housing. However, the obstruction of the housing makes plug installation difficult, reducing installation efficiency. Therefore, we propose an anti-slip tube connector for traffic lights. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an anti-slip pipe connector for traffic lights, which effectively solves the problem that the plug needs to be tightened from the inside of the traffic light box, and the blockage of the light box makes it difficult to install the plug, thus reducing the installation efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip pipe connector for traffic lights, comprising a bend pipe, an adjusting cap being provided at the top of the bend pipe, a threaded groove being provided on the inner wall of the adjusting cap, a plug being provided on the inner wall of the adjusting cap, the plug being hollow, a limiting tube being provided at the lower end of the plug, the lower side of the inner wall of the bend pipe being square, and the outer wall of the limiting tube matching the lower side of the inner wall of the bend pipe.

[0005] Preferably, the outer wall of the adjusting cap is provided with a worm gear, the outer wall of the bend is provided with a mounting bracket, and the front and rear side walls of the inner cavity of the mounting bracket are provided with worms, which mesh with the worm gear.

[0006] Preferably, the bottom wall of the plug is provided with a limiting groove, the inner wall of the limiting groove is provided with a limiting ring, and the bottom wall of the limiting ring is uniformly provided with toothed grooves.

[0007] Preferably, the top wall of the adjusting cap is provided with a sealing ring, and the bottom wall of the plug is provided with a closing ring, the closing ring being located outside the limiting ring.

[0008] Preferably, the inner wall on the right side of the bend is provided with a connecting thread, and a support pipe is provided on the inner wall on the right side of the bend.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This utility model discloses an anti-slip pipe connector for traffic lights. The top end of the bend pipe 100 is rotatably connected to an adjusting cap 101, which facilitates the movement of a plug 102. The inner wall of the adjusting cap 101 has a threaded groove, which also facilitates the movement of the plug 102. The plug 102 is slidably connected to the inner wall of the adjusting cap 101. The plug 102 and the adjusting cap 101 cooperate to clamp and install the light box. The plug 102 is hollow, which facilitates wire threading. The lower end of the plug 102 is fixedly connected to a limiting tube 103, which facilitates the movement of the plug 102. The lower side of the inner wall of the bend pipe 100 is square, which prevents the limiting tube 103 from deflecting. The outer wall of the limiting tube 103 matches the lower side of the inner wall of the bend pipe 100.

[0021] In this embodiment: the traffic light box is placed on the top wall of the bend pipe 100. The plug 102 is inserted into the inner cavity of the bend pipe 100 after passing through the light box. The plug 102 is moved by rotating the adjusting cap 101. The movement of the plug 102 facilitates the clamping and installation of the light box. The lower side of the inner wall of the bend pipe 100 is square, which facilitates the limiting and guiding of the movement of the plug 102 and prevents the plug 102 from deflecting. This makes it easy for the device to clamp and install the traffic light box, and it is easy to screw it on from the outside, which is beneficial for the installation and fixation of the traffic light box.

[0022] The outer wall of the adjusting cap 101 is fixedly connected to a worm gear 104, which facilitates the rotation of the adjusting cap 101. The outer wall of the bend pipe 100 is fixedly connected to a mounting bracket 105, which facilitates the support of the worm 106. The front and rear side walls of the inner cavity of the mounting bracket 105 are rotatably connected to the worm 106, which facilitates the rotation of the worm gear 104. The worm 106 meshes with the worm gear 104.

[0023] In this embodiment: the worm gear 106 drives the worm wheel 104 to rotate, and the adjusting cap 101 rotates through the worm wheel 104. The rotation of the adjusting cap 101 facilitates the movement of the plug 102, and the movement of the plug 102 facilitates the clamping and installation of the light box. This makes the device easy to clamp and install the light box. The worm gear 106 provides transmission, which facilitates the turning of the adjusting cap 101. The worm gear 106 transmission has self-locking properties, which can prevent the adjusting cap 101 from deflecting after the outer wall is installed, which is beneficial for clamping and installing the light box.

[0024] The bottom wall of the plug 102 is provided with a limiting groove, and the inner wall of the limiting groove is provided with a limiting ring 107. The bottom wall of the limiting ring 107 is evenly provided with toothed grooves.

[0025] In this embodiment: the movement of the plug 102 drives the movement of the limiting ring 107, and the movement of the limiting ring 107 clamps and fixes the light box. The grooves on the limiting ring 107 abut against the light box to prevent the light box from deflecting. This allows the device to make the teeth press against the outer wall of the traffic signal light to achieve the purpose of anti-slip and to facilitate the limiting support of the light box.

[0026] The top wall of the adjusting cap 101 is fixedly connected with a sealing ring 108, and the bottom wall of the plug 102 is fixedly connected with a closing ring 109. The closing ring 109 is located outside the limiting ring 107, and both the sealing ring and the closing ring are made of rubber.

[0027] In this embodiment, the sealing ring 108 and the sealing ring 109 are set to facilitate the fitting and sealing of the light box, which facilitates the sealing of the interface, prevents liquid from seeping in and causing corrosion, and improves the practicality of the device.

[0028] A connecting thread is provided on the inner wall of the right side of the bend pipe 100, and a support pipe 110 is screwed onto the inner wall of the right side of the bend pipe 100.

[0029] In this embodiment, the bend pipe 100 is screwed to the outer wall of the support pipe 110. The support pipe 110 facilitates the support of the bend pipe 100, makes screwing easier, and is beneficial for the installation and support of the traffic light box.
