Description

Technical Field

[0001] The utility model belongs to the technical field of wire passing boxes, and specifically relates to a wire passing box with a positioning structure. Background Technique

[0002] The wire passing box, also known as the junction box, is a product that centrally arranges the branched wires at a specific position to facilitate wire threading, wire splitting, and transition wiring. And when the current is too large or a short circuit occurs, the internal protection circuit automatically cuts off the circuit to prevent damage to the wires and cables or accidents such as fires.

[0003] Most wire passing boxes are installed on the wall through floor bolts. During installation, in order to ensure the stability, safety, and convenience of the entire electrical system, positioning operations are required to ensure the accuracy and perpendicularity of the wire passing box.

[0004] Currently, the common installation methods of wire passing boxes on the market mostly adopt fixed installation, that is, directly fixing the wire passing box on the wall. However, in the actual construction process, due to factors such as uneven walls and construction errors, the wire passing box is prone to skew during installation, resulting in inaccurate installation positions or non-compliant perpendicularity, affecting the aesthetics of the electrical system, and also easily having an adverse impact on the connection quality and service life of the wires, and even posing potential safety hazards. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes a wire passing box with a positioning structure.

[0007] Preferably, pull rods slidably penetrate through both sides of one end of the wire inlet pipe, and a sealing block is fixedly connected to one end of the pull rod; a spring is arranged on the pull rod at one end of the wire inlet pipe; a flexible layer is arranged on one side of the sealing block, and the flexible layer is made of polyimide material.

[0008] Preferably, a connecting plate is fixedly connected to one side of the edge of the base plate, and a clamping plate is slidably connected to the corresponding side of the edge of the base plate; a screw rod is rotatably connected to the outside of the clamping plate, and the other end of the screw rod threadedly penetrates through the inside of the connecting plate; a rubber layer is arranged at the bottom end of the worm.

[0009] Preferably, a plurality of connecting pipes are connected inside the box body, and a pipe cap is provided at one end of the connecting pipe; an internal thread is provided on the inner wall of the connecting pipe, and an external thread is correspondingly provided on the outer wall of the inlet pipe.

[0010] Preferably, a sealing ring is sleeved on the top end of the box body, and the sealing ring fits with the outer diameter of the top end of the box body.

[0011] Preferably, an accessory bag is connected inside the mounting hole through a wire harness, and the wire harness is made of thermoplastic elastomer material.

[0012] Preferably, a waterproof layer is provided at the bottom of the substrate, and a corrosion-resistant layer is provided on the waterproof layer.

[0013] Advantages of the present utility model:

[0014] 1. The present utility model provides a wire passing box with a positioning structure. The substrate can be installed at a specified position on the wall through expansion screws in cooperation with the mounting holes. After the installation is completed, continuously rotate the worm at this time. Through the meshing of its helical teeth with the helical teeth of the worm wheel, the rotational motion is transmitted to the worm wheel, and then the rotating plate can be driven to rotate inside the substrate, so as to achieve the purpose of adjusting the angle of the box body, so as to quickly rotate the box body to the required position, so as to solve the skew problem occurring during the installation of the wire passing box, reduce the impact on the subsequent circuit safety and quality caused by the skew, and at the same time utilize the self-locking property of the worm wheel and the worm to reduce the occurrence of accidental rotation of the box body caused by external impact and collision, so as to enhance the safety and reliability during use. The positioning frame is cross-shaped, so that when personnel are adjusting, through an external measuring tool, such as a spirit level, a plumb rule or an angle gauge and other tools for comparison measurement, the measuring tool can be more easily placed along a predetermined direction, such as horizontal, vertical or a specific angle, and aligned with the corresponding part on the positioning frame, so as to perform precise measurement to achieve the positioning effect.

[0015] 2. The present utility model provides a wire passing box with a positioning structure. When it is necessary to open the inlet pipe to allow the cable to pass through, pull the pull rod outwards to overcome the elastic force of the spring, so that the two sealing blocks move away from each other, creating a space for the line to enter and exit. After the line installation is completed, release the pull rod. Under the action of the spring return force, the two sealing blocks move closer to each other to seal the inside of the inlet pipe, and through the flexible layer, the sealing blocks can undergo simple deformation following the shape of the cable to adapt to cables of different diameters and shapes, so as to improve the sealing effect and reduce the entry of dust, moisture or other impurities into the box body through the inlet pipe.
