[0033] See also Figure 1-6 .

[0034] The present invention provides a technical solution for an external distribution box mounting frame: an external distribution box mounting frame, comprising a distribution box body 1, suitable for the installation of the external distribution box, and also comprising: an installation component 2, comprising a mounting platform 201 and limit piles 202 symmetrically arranged on the upper end of the mounting platform 201, for fixing the distribution box body 1; a fixing component 3, arranged at one end of a wall, for fixing the mounting platform 201; a power component 4, arranged on one side of the fixing component 3, for driving the installation component 2 to move on the fixing component 3; a self-locking component 5, arranged on the other side of the fixing component 3, for locking the installation component 2 after moving to the top of the fixing component 3.

[0035] By setting the installation component 2, the fixing component 3, the power component 4 and the self-locking component 5, the distribution box body 1 is installed on the installation component 2, and the installation component 2 is transported to the upper end of the fixing component 3 by using the power component 4, and then the installation component 2 is fixed to the upper end of the fixing component 3 by the self-locking component 5. When the distribution box body 1 needs to be lowered, the installation component 2 can be slowly lowered by releasing the self-locking component 5 and using the power component 4, so that the installation and replacement of the distribution box body 1 can be quickly completed.

[0036] In one embodiment, a symmetrically arranged sliding groove 2011 is provided on the upper end surface of the mounting platform 201, a telescopic column 203 is slidably arranged in the sliding groove 2011, a telescopic spring 2031 is fixedly arranged on one side of the telescopic column 203, and the other end of the telescopic spring 2031 is fixedly arranged at the bottom end of the sliding groove 2011, a moving bar 204 is fixedly arranged at the lower end of the limiting pile 202, a plurality of contacts 2021 are provided on the side wall of the limiting pile 202, a rotating gear 205 is rotatably provided in the sliding groove 2011, the moving bar 204 and the telescopic column 203 are both engaged with the rotating gear 205, and a plurality of square holes are provided at corresponding positions at the bottom of the distribution box and on the mounting platform 201 for connecting cables from the distribution box to the outside.

[0037] With such a design, the distribution box body 1 is placed on the mounting platform 201, and the bottom end of the distribution box body 1 will squeeze the telescopic column 203 on the mounting platform 201 downward, and the telescopic spring 2031 on one side of the telescopic column 203 is compressed. One end of the telescopic column 203 is provided with teeth adapted to the rotating gear 205. Therefore, when the telescopic column 203 moves downward, it will drive the rotating gear 205 to rotate, and the rotation of the rotating gear 205 will drive the moving bar 204 on the other side to move, thereby driving the limit pile 202 to move in a direction approaching each other. When the contact 2021 on the side wall of the limit pile 202 conflicts with the side wall of the distribution box body 1, the installation and fixation of the distribution box body 1 is completed.

[0038] In one embodiment, the fixing assembly 3 includes a fixing frame 301 fixedly mounted on a wall and a rotating shaft 302 rotatably mounted on a top end of one side of the fixing frame 301 , and a receiving groove 3021 is formed on the rotating shaft 302 .

[0039] The storage groove 3021 is designed in this way to allow the steel cable 403 to be wound when it is rolled up, and one end of the fixing frame 301 is fixedly arranged on the wall.

[0040] In one embodiment, the power assembly 4 includes a motor 401 and a transmission belt 402 arranged on one side of the motor 401. The motor 401 can rotate forward and reverse. This is a prior art and will not be described in detail herein. A transmission disc 2 4022 and a transmission disc 1 4021 are respectively arranged at the upper and lower ends of the transmission belt 402. One side of the transmission disc 2 4022 is fixedly arranged at one end of the rotating shaft 302, and one side of the transmission disc 1 4021 is fixedly arranged at the output end of the motor 401. An extension frame 2012 is fixedly arranged at one end of the mounting platform 201, and symmetrically arranged steel cables 403 are fixedly arranged on the extension frame 2012. The other end of the steel cable 403 is fixedly arranged on the rotating shaft 302.

[0041] With this design, when the motor 401 is started, it will drive the transmission disc 1 4021 to rotate through the output end, and the transmission disc 1 4021 will drive the transmission disc 2 4022 to rotate through the transmission belt 402, and the transmission disc 2 4022 will drive the rotating shaft 302 to rotate, thereby driving the steel cable 403 to reel in, and the reeling of the steel cable 403 will drive the mounting platform 201 to move upward, and the extension frame 2012 on the mounting platform 201 will slide on the side wall of the fixed frame 301.

[0042] In one embodiment, the self-locking component 5 includes a protective cover 2 501 fixedly arranged on a side of the fixed frame 301, a ratchet 502 and a ratchet 503 arranged inside the protective cover 2 501, one side of the ratchet 502 is fixedly arranged at one end of the rotating shaft 302, a fixing ring 504 is fixedly arranged on the inner side wall of the protective cover 2 501, one end of the ratchet 503 is slidably connected to the inner side wall of the fixing ring 504, a moving column 505 is fixedly arranged on one end of the ratchet 503, and a return spring 506 is sleeved on the outer side wall of the moving column 505, one end of the return spring 506 is fixedly arranged on one side of the fixing ring 504, a pressing strip 507 is fixedly arranged on the other end of the moving column 505, and the other end of the return spring 506 is fixedly arranged on one end of the moving column 505 close to the pressing strip 507, a movable opening 5011 for sliding the pressing strip 507 is opened on one side of the protective cover 2 501, and a protective cover 1 404 for protecting the transmission belt 402 is fixedly arranged on the other end of the fixed frame 301.

[0043] With this design, when the mounting platform 201 moves upward and the rotating shaft 302 rotates, the ratchet 503 will not get stuck with the ratchet 502. After the mounting platform 201 moves to the top, the ratchet 503 will get stuck with the ratchet 502 so that it will not rotate in the opposite direction, and the mounting platform 201 will be locked. When it is necessary to lower the mounting platform 201, the pressing bar 507 is pressed downward manually. At this time, the reset spring 506 will be pulled, and the moving column 505 drives the ratchet 503 to move downward. The ratchet 502 loses its resistance and will not block the reverse rotation of the rotating shaft 302. At this time, the rotating shaft 302 is driven by the motor 401 to rotate in the opposite direction. Since the radius of the transmission disk 1 4021 and the transmission disk 2 4022 are quite different, the rotating shaft 302 will rotate slowly, so that the mounting platform 201 and the distribution box body 1 will slowly move downward.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
