DETAILED DESCRIPTION

[0023] The following will be combined with 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 of 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.

[0024] Example 1

[0025] like Figure 1~Figure 5 As shown, the present embodiment proposes a safe power distribution switch control device, including a positioning seat 1, four end corners of one end of the positioning seat 1 are fixedly connected to limit rods 2, a circuit breaker body 3 is slidably connected between the plurality of limit rods 2, a ventilation window 4 is provided in the middle of the positioning seat 1, a positioning frame 6 is fixedly connected to the inner side of the positioning seat 1, both ends of the positioning frame 6 are fixedly connected to support frames 7, a transmission shaft 8 is rotatably connected to the inner side of the support frame 7, a guide frame 9 is fixedly connected to the outer side of the transmission shaft 8, a positioning plate 10 is fixedly connected to one end of the guide frame 9, a linkage mechanism 11 is provided between the two support frames 7, and the linkage mechanism 11 is used to cooperate with the positioning plate 10 to quickly position the circuit breaker body 3;

[0026] In detail, the top and bottom ends of the positioning seat 1 are fixedly connected to the extension seat, and a waist hole is opened inside the extension seat. Through the setting of the waist hole, the connecting piece can be effectively avoided, so that the positioning seat 1 can be stably assembled;

[0027] The air vent 4 is fixedly connected to a dust screen 5, which is made of a breathable material. The dust screen 5 can prevent dust from passing through the air vent 4 and being adsorbed on the dust screen 5 while ensuring the heat dissipation effect of the circuit breaker body 3.

[0028] Specifically, a plurality of heat dissipation holes are provided at one end of the positioning plate 10, and a protective pad is fixedly connected to one end of the positioning plate 10 close to the circuit breaker body 3. Through the provision of the heat dissipation holes, after the positioning plate 10 contacts the circuit breaker body 3, the heat on the surface of the circuit breaker body 3 will be dissipated outward through the heat dissipation holes to avoid heat accumulation.

[0029] Example 2

[0030] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a linkage mechanism 11;

[0031] In this embodiment, the linkage mechanism 11 includes an assembly frame 12, a linkage shaft 13, a linkage worm wheel 14, a linkage worm 15, a force grip 16, a locking shaft 17 and a locking hole 18. The top ends of the two support frames 7 are fixedly connected with the assembly frames 12, the linkage shaft 13 is rotatably connected between the two assembly frames 12, the top ends of the two transmission shafts 8 are fixedly connected with the linkage worm wheels 14, the outer side of the linkage shaft 13 is fixedly connected with two linkage worm wheels 15, the two linkage worm wheels 15 are mirror-set, and the two linkage worm wheels 15 are respectively meshed with the two linkage worm wheels 14, one end of the linkage shaft 13 is fixedly connected with the force grip 16, one side of the force grip 16 is slidably connected with the locking shaft 17, and one end of an assembly frame 12 closest to the locking shaft 17 is provided with a plurality of locking holes 18, and the locking shaft 17 is snap-connected with the locking hole 18;

[0032] In summary, the linkage shaft 13 is rotated to cause the two linkage worms 15 to respectively move the two linkage worm wheels 14, and the connection between the transmission shaft 8 and the guide frame 9 is coordinated, so that the positioning plate 10 can be close to the circuit breaker body 3 until it is tightly fitted with the circuit breaker body 3, thereby completing the assembly of the circuit breaker body 3. After the linkage shaft 13 is transmitted, the locking shaft 17 is pushed to cause the locking shaft 17 to be stuck in the locking hole 18, thereby forming a stop limit of the linkage shaft 13;

[0033] Here, one side of the force-bearing handle 16 is fixedly connected to a stabilizing seat, and the locking shaft 17 is slidably connected to one end of the stabilizing seat. The middle part and one end of the locking shaft 17 are fixedly connected to a limiting plate, and the diameter of the limiting plate is larger than the diameter of the stabilizing seat. Through the arrangement of the stabilizing seat and the limiting plate, the locking shaft 17 can be easily mounted to ensure the stability of the locking shaft 17.

[0034] A specific application of the above two embodiments is that first, the positioning seat 1 is positioned at a specified position through a connecting piece, and the position of the circuit breaker body 3 is formed by the limiting rod 2, and then the linkage shaft 13 is rotated by the force-bearing handle 16, so that the two linkage worms 15 respectively move the two linkage worm wheels 14, thereby driving the transmission shaft 8 to rotate. Since the two linkage worms 15 are arranged in a mirror image, the rotation directions of the two transmission shafts 8 are opposite. With the connection between the transmission shaft 8 and the guide frame 9, the positioning plate 10 can be close to the circuit breaker body 3 until it is tightly fitted with the circuit breaker body 3, thereby completing the assembly of the circuit breaker body 3. After the linkage shaft 13 is transmitted, the locking shaft 17 is pushed to cause the locking shaft 17 to be stuck in the locking hole 18, thereby forming a stop limit of the linkage shaft 13;

[0035] In summary, the circuit breaker body 3 is positioned by using the contact between the positioning plate 10 and the circuit breaker body 3. In the subsequent process, the positioning plate 10 can be removed by simply moving it away from the circuit breaker body 3, making the overall process more convenient.

[0036] Furthermore, through the structural cooperation between the air-permeable window 4 and the positioning plate 10 , the circuit breaker body 3 can be stably assembled, and the heat dissipation of the circuit breaker body 3 can be guaranteed to a greater extent, making the whole body safer.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
