[0029] like Figure 1-5 As shown, the embodiment of the present invention provides a bus duct fixing bracket structure that is shockproof and pressure-resistant, including a base 1 and a fixing block 2. The fixing block 2 is symmetrically arranged on the left and right sides of the top of the base 1. An anti-vibration component 3 is arranged on the inner side of the fixing block 2. The anti-vibration component 3 includes a connecting frame 302, a fixing plate 303 and a hard spring 305. The connecting frame 302 is movably connected to the inner cavity of the fixing block 2, and the surface is cross-arranged through a rotating shaft. The number of the connecting frames 302 is three groups, and the three groups of connecting frames 302 are equidistantly distributed on the inner side of the fixing block 2. The fixing plate 303 is located on the inner side of the fixing block 2. The three groups The other end of the connecting frame 302 is movably connected to the outside of the fixed plate 303, and the hard spring 305 is fixedly connected to the four sides of the outside of the fixed plate 303. The other end of the hard spring 305 is fixedly connected to the inner cavity of the fixed block 2. A guide rod 304 is fixedly installed around the outside of the fixed plate 303 and on the inner side of the hard spring 305. A through hole 306 is opened around the outside of the fixed block 2. The guide rod 304 passes through the through hole 306 and extends to the outside of the fixed block 2. The other end of the guide rod 304 is fixedly installed with a limit block 301, and the diameter of the limit block 301 is larger than the through hole 306.

[0030] By setting up the shockproof component 3, the overall stability and reliability can be improved, which helps to effectively absorb and disperse external vibrations, prevent the bus duct from being damaged by vibration, and thus ensure the normal operation of the power system. The pressure-resistant structure enhances the stability when bearing heavy loads, prevents deformation or rupture due to excessive pressure, extends the service life of the bus duct, and reduces maintenance costs and potential safety risks.

[0031] Example 2

[0032] In one embodiment, a fixing assembly 4 is provided on the inner side of the base 1, and the fixing assembly 4 is connected to the fixing block 2 and is used to drive the fixing block 2 to move horizontally along the base 1. The fixing assembly 4 includes a bidirectional threaded rod 401 and a threaded sleeve 402. The bidirectional threaded rod 401 is movably connected to the inner cavity of the base 1, and the threaded sleeve 402 is threadedly connected to the left and right sides of the surface of the bidirectional threaded rod 401. The left end of the bidirectional threaded rod 401 is fixedly connected to a knob 403. The left and right sides of the top of the base 1 are provided with through grooves 404. The top of the threaded sleeve 402 passes through the through groove 404 and is fixedly connected to the bottom of the fixing block 2. Guide grooves 405 are provided on the front and back sides of the inner cavity of the base 1, and guide blocks 406 are fixedly installed on the front and back sides of the surface of the threaded sleeve 402. The guide blocks 406 are slidably connected to the inner side of the guide groove 405. The top of the base 1 is fixedly installed with a frame 5, and the inner side of the frame 5 is fixedly installed with a pressure plate 6. A slide groove 7 is provided on the top of the fixed block 2, and the fixed block 2 is movably connected to the outer side of the pressure plate 6 through the slide groove 7. Mounting plates 8 are fixedly installed on all four sides of the surface of the base 1, and the surface of the mounting plate 8 is threadedly connected with a positioning bolt 9. The lower end of the positioning bolt 9 passes through the mounting plate 8 and extends to the bottom of the mounting plate 8.

[0033] By rotating the knob 403, the bidirectional threaded rod 401 is driven to rotate, and the threaded sleeve 402 and the fixed block 2 are driven to move inward under the action of the threaded connection, so that bus ducts of different sizes can be fixed. The setting of the guide groove 405 and the guide block 406 can play a guiding role to prevent the threaded sleeve 402 from offsetting during the movement. The setting of the pressure plate 6 can support the top of the fixed block 2, thereby improving the overall pressure resistance coefficient. The setting of the slide groove 7 can slide along the surface of the pressure plate 6 while the fixed block 2 moves, thereby improving the stability of the fixed block 2 during movement. The setting of the positioning bolt 9 can install and fix the base 1 to the outside.

[0034] When the utility model is in operation: after the bus duct is placed on the top of the base 1 and between the fixed blocks 2, the knob 403 is manually turned to drive the bidirectional threaded rod 401 to rotate. While the bidirectional threaded rod 401 rotates, it drives the threaded sleeve 402 and the fixed block 2 to move inward through the action of the threaded connection, and fixes the bus duct through the fixed plate 303. When external vibration occurs, the bus duct is affected by the vibration and squeezes the fixed plate 303 to both sides. After being squeezed, the fixed plate 303 will be displaced to both sides, thereby driving the connecting frame 302 to expand outward, and the fixing plate 303 is fixed by the connecting frame 302 to prevent the fixing plate 303 from lateral deviation during the movement. When the fixing plate 303 moves, it squeezes the guide rod 304. The guide rod 304 will be compressed after being squeezed and deformed. During the deformation process, it will absorb the pressure generated by the vibration, thereby protecting the bus duct.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
