[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a weak current box, including a weak current box body 1, a movable frame 2 is placed in the inner cavity of the weak current box body 1, a fixed block 3 is fixedly installed on the rear side of the movable frame 2, a threaded rod 4 is threadedly connected to the inner cavity of the fixed block 3, a movable rod 5 is movably sleeved in the inner cavity of the movable frame 2, and a switch door 6 is fixedly connected to the right side of the movable rod 5;

[0023] By placing the movable frame 2 and the fixed block 3 from the top of the weak current box body 1 into the inner cavity of the weak current box body 1, and then using the threaded rod 4 to fix the fixed block 3, people can use the switch door 6 to open and close the weak current box body 1. When the weak current box body 1 is damaged during long-term use, the threaded rod 4 is unscrewed from the inner cavity of the fixed block 3, and then the movable frame 2 is pulled out from the inner cavity of the weak current box body 1, and then the new movable frame 2 and fixed block 3 are inserted into the inner cavity of the weak current box body 1, and then the threaded rod 4 is screwed into the inner cavity of the fixed block 3, thereby realizing the rapid replacement of the switch door 6. When the switch door 6 is damaged, there is no need to disassemble and replace the weak current box body 1. It is simple, convenient and fast, and reduces the labor intensity of the staff.

[0024] Among them, the bottom end of the movable rod 5 is fixedly connected with a clamping rod 11, and the left and right sides of the clamping rod 11 are fixedly installed with a clamping plate 12. The inner cavity of the weak current box body 1 is fixedly installed with a coil spring cylinder 14, and the top end of the coil spring cylinder 14 is fixedly sleeved with a rotating block 13;

[0025] When the movable frame 2 is inserted into the inner cavity of the low-voltage box body 1, the clamping rod 11 and the clamping plate 12 enter the inner cavity of the rotating block 13. When the switch door 6 is opened, the clamping rod 11 and the clamping plate 12 at the bottom of the movable rod 5 drive the rotating block 13 to rotate, so that the spring tube 14 accumulates elastic potential energy. When the staff releases the switch door 6, the spring tube 14 loses its limit, and the spring tube 14 drives the rotating block 13 to rotate and reset, thereby driving the switch door 6 to reset, thereby realizing the automatic reset of the switch door 6, which is convenient and quick.

[0026] A circular hole is formed at the bottom of the movable frame 2, and the movable rod 5 passes through the circular hole and is fixedly connected to the clamping rod 11;

[0027] Through the circular hole at the bottom end of the movable frame 2 , the movable rod 5 can extend out of the inner cavity of the movable frame 2 , so as to be fixedly connected with the clamping rod 11 .

[0028] There are two threaded holes in the middle of the fixing block 3, and there are two threaded rods 4, which are respectively threadedly connected in the two threaded holes;

[0029] By setting the threaded rod 4, the fixing block 3 can be fixed by the threaded rod 4 after being inserted into the inner cavity of the weak current box body 1, thereby facilitating the replacement of the fixing block 3 and the movable frame 2.

[0030] Among them, a placement slot 10 is opened on the left side of the weak current box body 1, and the movable frame 2 and the fixed block 3 are both inserted into the inner cavity of the placement slot 10;

[0031] Through the placement slot 10 on the left side of the weak-current box body 1, the fixed block 3 and the movable frame 2 can be inserted into the inner cavity of the placement slot 10, thereby facilitating the replacement of the fixed block 3 and the movable frame 2. Therefore, when a failure occurs in the switch door 6, there is no need to disassemble and replace the weak-current box body 1.

[0032] Among them, a switch lock 7 is arranged on the right side of the switch door 6, and the switch door 6 is fitted with the weak current box body 1;

[0033] Through the switch lock 7 on the right side of the switch door 6, the staff can lock the switch door 6 through the switch lock 7, thereby protecting the components inside the weak-current box body 1, and then fit the switch door 6 with the weak-current box body 1 to ensure that the switch door 6 can protect the components in the inner cavity of the weak-current box body 1.

[0034] Among them, a magnetic attraction piece 1 8 is fixedly installed on the left side of the front side of the switch door 6, and a magnetic attraction piece 2 9 is fixedly installed on the left side of the weak current box body 1;

[0035] By setting the magnetic sheet 1 8 and the magnetic sheet 2 9, the switch door 6 can be magnetically attracted by the magnetic sheet 1 8 and the magnetic sheet 2 9 when it is opened to the maximum range, and then the switch door 6 is limited by the magnetic attraction of the magnetic sheet 1 8 and the magnetic sheet 2 9, so as to facilitate the staff to use the components in the inner cavity of the weak current box body 1.

[0036] The inner cavity of the rotating block 13 is provided with a card slot 15, and the card plate 12 is in contact with the inner wall of the card slot 15;

[0037] By setting the card slot 15, the card plate 12 can be stuck in the inner cavity of the card slot 15, so that the rotation of the switch door 6 can drive the rotating block 13 to rotate, and the winding spring tube 14 can drive the switch door 6 to automatically reset.

[0038] The working principle and use process of the utility model are as follows: when the switch door 6 needs to be replaced, the threaded rod 4 is screwed out from the threaded hole of the fixing block 3, and then the switch door 6, the movable frame 2, and the fixing block 3 are pulled out of the inner cavity of the placement groove 10, and then the new movable frame 2 and the fixing block 3 are inserted into the inner cavity of the placement groove 10, and then the threaded rod 4 is screwed into the threaded hole of the fixing block 3, so as to complete the replacement;

[0039] When the movable frame 2 is inserted, the clamping rod 11 at the bottom end of the movable rod 5 is inserted into the inner cavity of the rotating block 13, so that the clamping rod 11 and the clamping plate 12 are clamped in the inner cavity of the clamping groove 15. When the switch door 6 is opened, the spring tube 14 accumulates elastic potential energy. When the staff releases the switch door 6, the spring tube 14 loses its limit, and the switch door 6 is reset by the spring tube 14. When the switch door 6 needs to be fixed, the magnetic suction piece 1 8 and the magnetic suction piece 2 9 can be magnetically attracted.
