Description

Technical Field

[0001] The utility model relates to the technical field of bus duct fixing, in particular to a bus duct fixing device with a double clamping and positioning structure. Background Art

[0002] Enclosed bus duct, also known as bus duct, refers to the same thing. It consists of a busbar system made up of a metal (steel or aluminum) protective casing, conductive bars, insulation, and related accessories. It can be configured as a plug-in type with junction boxes installed at regular intervals, or as a feeder type without junction boxes.

[0003] The installation process of bus duct is usually installed by hanging it on the roof with hangers to facilitate wiring, but there are many problems when using conventional hangers for installation and fixation. First, the installation process is relatively cumbersome. During the installation process of the hanger and the installation process of the bus duct, a large number of bolt structures are required for connection and fixation. Not only is the installation efficiency low, but also during long-term use, the bolt structure is reversible and prone to falling off, which may cause danger. Bus ducts of different specifications also require hangers of different specifications, and the scope of application is narrow. Secondly, if only hangers are used for installation, when the bus duct shakes, the hanger may follow the shaking and it is difficult to stabilize quickly, which may cause the overall structure to fall off and the safety is not high.

[0004] The Chinese patent application with publication number CN117117746A discloses a bus duct fixing device, which suspends two lifting and clamping mechanisms on the top surface of the wall through a first mounting base, and then uses a second mounting base to install a quadrangular pyramid stabilizing mechanism in the middle position of the two lifting and clamping mechanisms, and then the bus duct is placed on the surface of the support frame and the cross plate, and then the second hexagonal nut is rotated with an inner hexagonal wrench to drive the rotating rod and the middle worm to rotate, and the worm drives the worm wheel and the rotating shaft to rotate, and the rotating shaft drives the gear on the lower outer diameter to rotate, and the meshing transmission between the gear and the rack plate drives the two rack plates and the connected movable block to move inward, thereby driving the inner end of the bent clamping rod on the connecting structure to move inward to complete the clamping action of the bus duct in the horizontal direction, and then the first hexagonal nut is rotated with an inner hexagonal wrench to drive the threaded rod to rotate, and the threaded rod is used to The meshing transmission with the slider drives the bending clamp rod to descend, so that the top of the bending clamp rod is pressed on the top of the bus duct, completing the clamping action in the vertical direction of the bus duct, that is, completing the overall installation action of the bus duct. The entire bus duct installation process does not use an additional bolt structure, the operation is simple, and the installation efficiency is improved. At the same time, the double clamping function in the horizontal and vertical directions is adopted to ensure the firmness of the installation, and the worm gear structure is used to complete the clamping action of the bending clamp rod. Since the worm gear has the irreversibility of transmission, the firmness of the installation is further improved. The middle part of the bus duct adopts a quadrangular pyramid stabilization mechanism as additional support. When the bus duct shakes, the top coupling seat will rotate around the movable axis, driving the coil springs on both sides to contract, and using the elastic potential energy generated by the contraction of the coil spring to perform limit callback, so that the bus duct can quickly stabilize during the shaking process.

[0005] However, the device still has defects. In actual operation, the mounting frame is often mass-produced, and the spacing of the adjustment holes on the mounting frame is fixed. The bolt structure is reversible, which can easily lead to loosening of the bolts, thereby easily causing the cross frame to fall off. The top surface of the wall has a slight error in level due to manual stacking, so the bus duct on the mounting frame cannot be guaranteed to be level, resulting in inconvenience in use.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figures 1 to 6 As shown, a bus duct fixing device with a double clamping positioning structure includes a bus duct 1, a first support frame 2 and a second support frame 3; the first support frame 2 and the second support frame 3 are arranged on both sides of the bus duct 1; the first support frame 2 and the second support frame 3 have the same structure, and the first support frame 2 and the second support frame 3 both include a transverse support frame 21 and a longitudinal support frame 22, and the number of the longitudinal support frames 22 is a pair and is arranged on both sides of the transverse support frame 21; a lifting device 222 is provided on the longitudinal support frame 22, and a pair of fixing devices 221 are cross-arranged on both sides of the lifting device 222, and an infrared level is also provided on the longitudinal support frame 22; a horizontal sliding device 211 is provided on the transverse support frame 21, and the output end of the horizontal sliding device 211 is provided with a first clamping device 212 and a second clamping device 213 side by side, and the output ends of the first clamping device 212 and the second clamping device 213 are in contact with the bus duct 1.

[0026] When the bus duct 1 needs to be fixed, the operator can clamp and fix the bus ducts 1 of different sizes through the setting of the first clamping device 212 and the second clamping device 213. At this time, the infrared level meter is used to determine whether the two sides of the transverse support frame 21 are in a horizontal state. The height of the two sides of the transverse support frame 21 can be adjusted by setting the lifting device 222. After the adjustment is completed, the lifting device 222 can be fixed by setting the fixing device 221 to prevent the reversibility of the output end of the lifting device 222 due to the gravity of the bus duct 1, thereby causing the adjusted transverse support frame 21 to tilt, which makes it inconvenient to use.

[0027] See also Figure 4 As shown, the lifting device 222 includes a second threaded rod 2221 and a turning handle 2222 ; the second threaded rod 2221 is rotatably arranged on the longitudinal support frame 22 ; the turning handle 2222 is arranged on the second threaded rod 2221 .

[0028] When it is necessary to implement the lifting device 222 to adjust the height of the transverse support frame 21, the handle 2222 is rotated to make the handle 2222 drive the second threaded rod 2221 to rotate. The transverse support frame 21 is provided with a through hole for the second threaded rod 2221 to pass through, and the inside of the through hole is provided with a thread that engages with the second threaded rod 2221. Therefore, when the second threaded rod 2221 rotates, the transverse support frame 21 slides along the direction of the second threaded rod 2221, thereby realizing the adjustment of the height of the transverse support frame 21.

[0029] See also Figure 5 and Figure 6 As shown, the fixing device 221 includes a fixed rod 2211, a telescopic rod 2213, a spring 2215 and a limiting rod 2216; the fixed rod 2211 is arranged on one side of the longitudinal support frame 22 close to the turning handle 2222; the limiting rod 2216 is arranged inside the fixed rod 2211; the telescopic rod 2213 is slidably arranged on the limiting rod 2216; the spring 2215 is sleeved on the limiting rod 2216, one side of the spring 2215 is connected to the fixed rod 2211, and the other side of the spring 2215 is connected to the telescopic rod 2213.

[0030] In the initial state, the outer wall of the telescopic rod 2213 abuts against the turning handle 2222, so that the turning handle 2222 cannot be rotated due to external force. At this time, the spring 2215 is in a relaxed state. When the turning handle 2222 needs to be rotated, the operator can press the telescopic rod 2213 toward the limit rod 2216, and the spring 2215 is compressed until the outer wall of the telescopic rod 2213 is out of contact with the turning handle 2222, thereby realizing the rotation adjustment of the turning handle 2222.

[0031] See also Figure 5 and Figure 6 As shown, a fixing block 2214 is provided on the periphery of the telescopic rod 2213 , and an L-shaped sliding groove 2212 for the fixing block 2214 to slide is provided on the fixing rod 2211 .

[0032] When the telescopic rod 2213 needs to be fixed, the telescopic rod 2213 is pressed toward the side of the limit rod 2216 to compress the spring 2215, and the fixed block 2214 slides along the L-shaped groove 2212 until the fixed block 2214 slides to the bottom of the L-shaped groove 2212. At this time, by rotating the telescopic rod 2213, the fixed block 2214 is engaged with the L-shaped groove 2212, thereby releasing the restriction on the turning handle 2222, and then the turning handle 2222 can be rotated as needed to adjust the height of the horizontal support frame 21.

[0033] See also Figures 2 to 4 As shown, the horizontal sliding device 211 includes a rotating rod 2111, a handle 2112, a first gear 2113, a second gear 2114, a bidirectional screw rod 2115, a first sliding frame 2116, a second sliding frame 2117 and a horizontal sliding mechanism; the rotating rod 2111 is rotatably set at the bottom of the horizontal support frame 21; the handle 2112 is set on the rotating rod 2111; the first gear 2113 is set on the rotating rod 2111, and the outer teeth of the first gear 2113 are engaged with the second gear 2114; the bidirectional screw rod 2115 is rotatably set on the horizontal support frame 21; the second gear 2114 is set on the bidirectional screw rod 2115; the first sliding frame 2116 and the second sliding frame 2117 are slidably set on both sides of the bidirectional screw rod 2115.

[0034] When it is necessary to fix the bus ducts 1 of different widths, the operator can rotate the handle 2112 so that the handle 2112 drives the rotating rod 2111 to rotate when it rotates, and the rotating rod 2111 drives the first gear 2113 to rotate, and the second gear 2114 drives the bidirectional screw rod 2115 to rotate synchronously. The first sliding frame 2116 and the second sliding frame 2117 are provided with a through hole for the bidirectional screw rod 2115 to pass through, and the inside of the through hole is provided with a thread that engages with the bidirectional screw rod 2115. Therefore, when the bidirectional screw rod 2115 rotates, the first sliding frame 2116 and the second sliding frame 2117 move toward or in the opposite direction, thereby driving the lateral movement of the first clamping device 212 and the second clamping device 213, so that the first clamping device 212 and the second clamping device 213 can clamp and fix the bus ducts 1 of different widths.

[0035] See also Figures 2 to 4 As shown, the handle 2112 is provided with multiple groups of anti-sliding blocks.

[0036] By providing the anti-sliding block, the friction between the hand and the handle 2112 is increased when the handle 2112 is turned, thereby making it easier to turn the handle 2112.

[0037] See also Figures 2 to 4 As shown, the first clamping device 212 and the second clamping device 213 have the same structure. Both the first clamping device 212 and the second clamping device 213 include a rotating handle 2121, a first threaded rod 2122 and a clamping block 2123; the first threaded rod 2122 is rotatably set on the first sliding frame 2116; the clamping block 2123 is slidably set on the first threaded rod 2122; the rotating handle 2121 is set at the top of the first threaded rod 2122.

[0038] When it is necessary to fix the bus ducts 1 of different thicknesses, the operator can rotate the rotating handle 2121 so that the rotating handle 2121 drives the first threaded rod 2122 to rotate while rotating. The clamping block 2123 is provided with a through hole for the first threaded rod 2122 to pass through, and the inside of the through hole is provided with a thread that engages with the first threaded rod 2122. Therefore, when the first threaded rod 2122 rotates, the clamping block 2123 moves up and down along the direction of the first threaded rod 2122, thereby enabling the clamping block 2123 to clamp the bus ducts 1 of different thicknesses.

[0039] See also Figures 2 to 4 As shown, a rubber friction block is provided on one side of the clamping block 2123 away from the first threaded rod 2122 .

[0040] By providing the rubber friction block, the friction force between the clamping block 2123 and the bus duct 1 is increased, so that the fixing effect of the bus duct 1 is better.

[0041] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
