[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0027] In related technologies, distribution boxes are important equipment in power engineering, and they are pre-installed with cable holes for cables to pass through. In actual production and commissioning, especially for new products or projects, it is often necessary to add new functions or external control devices, which requires adding cable holes to the box.

[0028] This embodiment provides a device for opening holes in a distribution box, which can be used to manually complete the opening operation.

[0029] Please see Figure 1-Figure 2 In this embodiment, a distribution box enclosure opening device includes a bracket 10, a positioning cylinder 20, and a drill rod 30; wherein, the two ends of the bracket 10 are fixedly connected to opposing bases 11 and sleeves 12; the positioning cylinder 20 is screwed into the sleeve 12; the drill rod 30 is screwed into the positioning cylinder 20, and a locking member 31 is slidably connected to the drill rod 30, the locking member 31 can engage with the positioning cylinder 20, so that the positioning cylinder 20 rotates synchronously with the drill rod 30.

[0030] By adopting the technical solution of this embodiment, the connection state between the positioning cylinder 20 and the drill rod 30 is changed by the locking member 31. After the positioning cylinder 20 and the base 11 clamp the side wall of the box, the drill rod 30 can be rotated inside the positioning cylinder 20 to complete the drilling operation.

[0031] In this embodiment, the bracket 10 is constructed as a U-shape. The base 11 and the sleeve 12 are fixedly connected to the two ends of the bracket 10. Both the base 11 and the sleeve 12 are constructed as cylinders, and the two ends of the bracket 10 are respectively fixedly connected to the circumferential surfaces of the base 11 and the sleeve 12. The base 11 and the sleeve 12 are arranged coaxially. For example, the outer diameters of the base 11 and the sleeve 12 are the same, and their axial lengths are the same. That is, the base 11 and the sleeve 12 are arranged symmetrically at both ends of the bracket 10.

[0032] It should be noted that the difference between the base 11 and the sleeve 12 is that the base 11 has a smooth inner wall clearance hole 13 at its axis, while the sleeve 12 has a threaded hole 14 at its axis. The clearance hole 13 is used for the drill rod 30 to pass through the box of the distribution box, and the threaded hole 14 is used to form a threaded connection with the positioning cylinder 20.

[0033] In this embodiment, the positioning cylinder 20 is constructed into a cylindrical shape. Both the inner and outer walls of the positioning cylinder 20 are threaded. The positioning cylinder 20 is inserted into the sleeve 12 and is threadedly connected to the sleeve 12. The drill rod 30 is inserted into the positioning cylinder 20 and is threadedly connected to the positioning cylinder 20. The drill rod 30 is coaxially arranged with the positioning cylinder 20. The end of the positioning cylinder 20 away from the base 11 is provided with a slot 21, which is used to engage with the locking member 31.

[0034] It should be noted that when the positioning cylinder 20 is rotated clockwise, the positioning cylinder 20 will rotate toward the base 11; when the drill rod 30 is rotated clockwise, the drill rod 30 will rotate toward the base 11.

[0035] In this embodiment, the drill rod 30 is screwed into the inside of the positioning cylinder 20. A groove 33 is provided on the outer wall of the drill rod 30, and the groove 33 extends along the axial direction of the drill rod 30. The locking member 31 is constructed in the shape of a disc and is sleeved on the outside of the drill rod 30 and is arranged coaxially with the drill rod 30. A retaining strip 34 is provided on the inner wall of the locking member 31. The retaining strip 34 is slidably engaged with the groove 33, so that the locking member 31 is only allowed to slide along the axial direction of the drill rod 30, preventing relative rotation between the locking member 31 and the drill rod 30. A retaining head 32 is provided at the end of the locking member 31 opposite to the positioning cylinder 20. The retaining head 32 is adapted to the shape of the retaining groove 21 on the positioning cylinder 20. When the locking member 31 moves along the axial direction of the drill rod 30 toward the positioning cylinder 20, the retaining head 32 can be engaged in the groove 21, so that the positioning cylinder 20 and the drill rod 30 are connected as a whole structure, preventing relative rotation between the drill rod 30 and the positioning cylinder 20.

[0036] For ease of operation, a handle 35 is fixed to the outer end of the drill rod 30.

[0037] When it is necessary to drill a hole in the distribution box, first, the bracket 10 is clamped onto the side wall of the box, and the base 11 is placed against the inner wall of the box. The handle on the drill rod 30 is located on the outside of the box. Then, while keeping the bracket 10 fixed, the locking member 31 is slid along the axis of the drill rod 30, and the clasp 32 on the locking member 31 is engaged with the slot 21 on the positioning cylinder 20, thereby connecting the positioning cylinder 20 and the drill rod 30 into a single structure. Then, the drill rod 30 is rotated clockwise by the handle 35, and the positioning cylinder 20 will rotate synchronously with the drill rod 30 until the side wall of the box is clamped between the base 11 and the positioning cylinder 20. Then, the clasp 32 on the locking member 31 is removed from the slot 21 on the positioning cylinder 20. After the locking member 31 is released, the drill rod 30 can rotate relative to the positioning cylinder 20. Continue to rotate the drill rod 30 clockwise by the handle 35 until the side wall of the box is penetrated, thus completing the drilling operation.

[0038] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
