[0021] Both sides of the fixed seat 31 are bent by the device body to form a movable groove 311, and the movable seat 32 is slidably embedded in the movable groove 311.

[0022] An upper limit groove 312 is formed at the top of the movable groove 311, and correspondingly, an upper limit platform 324 is arranged on the top of the movable seat 32, and the upper limit platform 324 is clamped under the upper limit groove 312 to limit the downward movement of the movable seat 32; the bottom of the movable groove 311 is recessed to form a lower limit groove 313, and correspondingly, a lower limit platform 325 is arranged on the protruding end surface of the outer wall of the movable seat 32, and the lower limit platform 325 is clamped in the lower limit groove 313 to limit the upward movement of the movable seat 32.

[0023] The side of the upper limit slot 312 extends downward from the fixing seat 31 body to form an elastic buckle plate 314 .

[0024] A positioning platform 315 is protruded from the bottom of the movable groove 311 , and the movable seat 32 is clamped on the positioning platform 315 .

[0025] The locking groove 323 is an internal threaded hole, and the external thread protruding from the outer cylindrical surface of the adjusting screw rod 33 is threadedly connected to the internal threaded hole.

[0026] The movable seat 32 is provided with a clearance groove 4 at a position corresponding to the locking groove 323 , and the clearance groove 4 extends through the positioning platform 315 .

[0027] The fixing seat 31 is welded and installed on the inner wall of the box body 1 .

[0028] The movable seat 32 , the elastic buckle plate 314 , and the locking nut 322 are integrally injection-molded from a plastic material.

[0029] Working principle: In order to adjust the height of the guide rail, a height adjustment structure is set to install the guide rail and the box.

[0030] The height adjustment structure includes a fixing seat welded on the inner wall of the box body and a fixing seat detachably embedded therein. The two ends of the guide rail are respectively inserted into the slots formed by the depressions on the end surface of the movable seat, thereby connecting the guide rail and the box body as a whole.

[0031] The height adjustment structure also includes an adjustment screw, which passes through the movable seat, the guide rail, the fixed seat in sequence and is pressed against the bottom of the box. When the height of the guide rail needs to be adjusted, the adjustment screw is rotated, and the adjustment screw and the locking nut provided on the top protrusion of the movable seat perform relative rotational motion, converting the rotational motion of the adjustment screw into a linear up and down motion of the guide rail, driving the movable seat to slide vertically in the movable groove, and synchronously driving the height adjustment of the guide rail. Furthermore, the setting of the locking nut ensures that the guide rail can be locked after being adjusted to an appropriate height, avoiding the guide rail from loosening and deviating due to external vibration or other reasons, and ensuring the stability and reliability of the electrical components in the distribution box.

[0032] In order to ensure that the travel of the movable seat is within a certain safety range, an upper limit slot and a lower limit slot are respectively provided at the top and bottom of the movable slot. Correspondingly, an upper limit platform and a lower limit platform are provided in the movable seat, which are respectively connected to the upper limit slot and the lower limit slot, limiting the movable seat to move only within the range of the movable slot, locking the movement travel of the guide rail, and ensuring that the guide rail is installed within a reasonable and safe range. When the guide rail needs to be disassembled, the adjustment screw is turned in the opposite direction, and the adjustment screw is disconnected from the box body. At this time, the movable seat is lifted up, the upper limit platform opens the elastic buckle plate, and the lower limit platform is separated from the lower limit slot. The guide rail can be disassembled along with the movable seat. Users do not need professional tools for disassembly and assembly, which greatly simplifies the installation and maintenance process and improves the convenience of operation.

[0033] At the same time, the movable seat, elastic buckle plate and locking nut are made of plastic material through integral injection molding, which has low production cost. It not only reduces the number of components and simplifies the production and assembly process, but also improves the overall structural strength and durability, and extends the service life of the product.

[0034] Compared with the traditional guide rail fixed height installation method, the height of the guide rail is adjusted through the height adjustment structure, which reduces the operation gap and the risk of misoperation. The electrical components can achieve the ideal installation gap, and the overall utilization rate of the distribution box is high. At the same time, the height adjustment structure can adapt to the installation of multiple types of distribution boxes and has strong flexibility, so it can be widely promoted.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
