[0030] See also Figure 1-5 , a mounting bracket for a switch, comprising a top plate 1 and a base 2, a plurality of splicing frames 3 are installed between the top plate 1 and the base 2, the lower ends of the top plate 1 and the splicing frames 3 are respectively recessed inward to form two fixed chambers 4, each of the fixed chambers 4 is provided with a bidirectional lead screw 5 for rotation, two movable seats 6 are threadedly connected to the bidirectional lead screw 5, the lower end of each movable seat 6 passes through the fixed chamber 4 and is fixedly connected to an L-shaped fixed block 7, the upper ends of the base 2 and the splicing frames 3 are respectively provided with four fixed grooves 8 matched with the fixed blocks 7, one end of the bidirectional lead screw 5 passes through the fixed chamber 4 and is fixedly connected to a turning handle 9;

[0031] The upper end of the splicing frame 3 is recessed inward to form a limit chamber 10, and two limit seats 11 are movably provided in the limit chamber 10. The upper end of each limit seat 11 passes through the limit chamber 10 and is fixedly connected to a fixing frame 12, and a pressing plate 13 is slidably connected to the fixing frame 12 through a track structure.

[0032] In this embodiment, the splicing frame 3 drives the four fixing blocks 7 to be inserted into the four fixing grooves 8 of the base 2 respectively, and the two turning handles 9 are turned in turn. The turning handles 9 drive the bidirectional screw 5 to rotate, so that the moving seat 6 moves along the fixing chamber 4 in the separation direction, and the moving seat 6 drives the fixing block 7 to move, so that the fixing block 7 is stuck in the fixing groove 8, thereby fixing the splicing frame 3 to the base 2. The same method can be used to splice the splicing frame 3 according to the number of switches to be installed, and finally the top plate 1 is fixed to the top of the top splicing frame 3 using the same method.

[0033] More specifically, multiple splicing frames 3 can be spliced ​​according to the number of switches to be installed, and the splicing process can be completed by turning the handle 9 so that the fixing block 7 is stuck in the fixing groove 8. When switches of different sizes need to be installed, the switch is placed on the splicing frame 3, and the limit seat 11 is moved according to the size of the switch, so that the limit seat 11 moves along the limit chamber 10, and the limit seat 11 drives the fixing frame 12 to move, thereby adjusting the distance between the two fixing frames 12. When the pressing plate 13 moves downward along the sliding connection with the fixing frame 12, the pressing plate 13 fixes the switch to the splicing frame 3.

[0034] See also Figure 1-5 As an implementation method for fixing the switch: a first bolt 14 is threadedly connected to the fixing frame 12, and the lower end of the first bolt 14 passes through the bracket and is rotatably connected to the pressing plate 13. A limiting rod 15 is fixedly provided in the limiting chamber 10, and the limiting rod 15 is slidably connected to the limiting seat 11.

[0035] Specifically, when the limit seat 11 moves, the limit seat 11 will move along the limit rod 15 and the limit chamber 10, and the limit seat 11 drives the fixed tooth 16 to move. When the position adjustment of the limit seat 11 is completed, the second bolt 17 is rotated so that the second bolt 17 rotates and moves in the direction of the fixed tooth 16. The second bolt 17 drives the rack 18 to move along the limit chamber 10 to fix the fixed tooth 16, thereby fixing the limit seat 11. The first bolt 14 is rotated and the first bolt 14 rotates and moves downward. The first bolt 14 drives the pressing plate 13 to move downward along the sliding connection with the fixing frame 12, so that the pressing plate 13 fixes the switch.

[0036] See also Figure 1-5 As an implementation method for heat dissipation of the switch: an air inlet pipe 19 is fixedly arranged on one side of each splicing frame 3, a support frame 20 is fixedly arranged in the air inlet pipe 19, a horizontal shaft 21 is rotatably arranged on the support frame 20, a plurality of fan blades 22 are fixedly arranged on the horizontal shaft 21, a vertical shaft 23 is rotatably arranged on the air inlet pipe 19, the vertical shaft 23 penetrates the air inlet pipe 19, a driving bevel gear 24 is fixedly arranged on the vertical shaft 23 extending into the air inlet pipe 19, the driving bevel gear 24 is meshedly connected with a driven bevel gear 25 fixedly arranged on the horizontal shaft 21, a driving chamber 26 is arranged in the base 2, a motor 27 is fixedly arranged in the driving chamber 26, a driving block 28 is fixedly arranged at the driving end of the motor 27 and the upper end of the vertical shaft 23, and each of the vertical shafts 23 is provided with a driving groove 29 matching the driving block 28.

[0037] Specifically, during the process of splicing the entire bracket, the splicing frame 3 drives the air inlet duct 19 and the vertical shaft 23 to move, so that the driving block 28 at the driving end of the motor 27 is inserted into the driving groove 29 of the vertical shaft 23. Using this method, the vertical shafts 23 on the spliced ​​multiple splicing frames 3 can be connected through the driving block 28 and the driving groove 29, and the motor 27 is started. The motor 27 drives the connected multiple vertical shafts 23 to rotate through the driving block 28 and the driving groove 29. The vertical shaft 23 drives the driving bevel gear 24 to rotate, and the driving bevel gear 24 drives the driven bevel gear 25 to rotate. The driven bevel gear 25 drives the horizontal shaft 21 to rotate, so that the horizontal shaft 21 drives the multiple fan blades 22 to rotate, thereby blowing air to the switch and accelerating the heat dissipation of the switch.

[0038] To sum up, when the overall equipment is in use:

[0039] When multiple splicing frames 3 need to be spliced, the splicing frame 3 drives the four fixing blocks 7 to be inserted into the four fixing grooves 8 of the base 2 respectively, and the two turning handles 9 are turned in turn. The turning handles 9 drive the bidirectional lead screw 5 to rotate, so that the moving seat 6 moves along the fixing chamber 4 in the separation direction, and the moving seat 6 drives the fixing block 7 to move, so that the fixing block 7 is stuck in the fixing groove 8, thereby fixing the splicing frame 3 to the base 2. The same method can be used to splice the splicing frame 3 according to the number of switches to be installed, and finally the top plate 1 is fixed to the top of the top splicing frame 3 using the same method.

[0040] When the switch needs to be installed on the splicing frame 3, the switch is placed on the splicing frame 3, and the fixing frame 12 is pushed according to the size of the switch. The fixing frame 12 drives the limiting seat 11 to move along the limiting rod 15 and the limiting chamber 10, so as to adjust the distance between the two fixing frames 12. At the same time, the limiting seat 11 drives the fixing teeth 16 to move. When the position adjustment of the limiting seat 11 is completed, the second bolt 17 is rotated so that the second bolt 17 rotates and moves in the direction of the fixing teeth 16. The second bolt 17 drives the rack 18 to move along the limiting chamber 10 to fix the fixing teeth 16, thereby fixing the limiting seat 11. The first bolt 14 is rotated so that the first bolt 14 rotates and moves downward. The first bolt 14 drives the pressing plate 13 to move downward along the sliding connection with the fixing frame 12, so that the pressing plate 13 fixes the switch.

[0041] When the switch in use needs to be quickly cooled, during the process of splicing the entire bracket, the splicing frame 3 drives the air inlet duct 19 and the vertical shaft 23 to move, so that the driving block 28 at the driving end of the motor 27 is inserted into the driving groove 29 of the vertical shaft 23. Using this method, the vertical shafts 23 on the spliced ​​multiple splicing frames 3 can be connected through the driving block 28 and the driving groove 29, and the motor 27 is started. The motor 27 drives the connected multiple vertical shafts 23 to rotate through the driving block 28 and the driving groove 29, and the vertical shaft 23 drives the driving bevel gear 24 to rotate, and the driving bevel gear 24 drives the driven bevel gear 25 to rotate, and the driven bevel gear 25 drives the horizontal shaft 21 to rotate, so that the horizontal shaft 21 drives the multiple fan blades 22 to rotate, thereby blowing air to the switch and accelerating the heat dissipation of the switch.

[0042] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
