Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, in particular to an earthquake-resistant bracket that can be quickly disassembled and assembled. Background Art

[0002] In engineering construction, the layout of cables often requires the use of cable trays, which are usually installed on the top of the wall. In order to improve the installation stability and avoid falling accidents due to disasters such as earthquakes, the cable tray is generally installed on the top of the wall using earthquake-resistant brackets.

[0003] For square objects, the installation of earthquake-resistant brackets is to fix the objects longitudinally and transversely respectively. Several connecting parts are needed in the process of fixing the objects. At the same time, the fixing process sometimes requires the use of tools, which makes the disassembly and assembly of the parts that need to be fixed more troublesome.

[0004] Therefore, a quick-disassembly and assembly anti-seismic bracket is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the installation of a traditional earthquake-resistant bracket is troublesome, and the utility model provides an earthquake-resistant bracket that can be quickly disassembled and assembled.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A quick-disassembly and assembly earthquake-resistant bracket comprises a connecting bracket, a base and a fixing device, wherein the interior of the base is a receiving cavity with an upper opening, the connecting brackets are in a plurality and are rotatably connected to the base respectively, a mounting plate is provided at the free end of the connecting bracket, and the fixing device comprises a transverse clamping mechanism and a longitudinal clamping mechanism.

[0008] Furthermore, the transverse clamping mechanism includes a gear, a first rack, a second rack, a reset member, a transverse pressure plate and a knob. There are two transverse pressure plates and they are relatively arranged on the upper part of the base. The gear is rotatably connected to the inner cavity of the base. The first rack and the second rack are relatively arranged with the gear as the center and are respectively meshed with the first rack and the second rack. The gear and the first rack are respectively fixed to the corresponding transverse pressure plate by a fixing rod. One end of the knob is coaxially fixed to the gear, and the other end passes through the base wall and extends to the outside. The reset member is used to reset the fixing rod.

[0009] Furthermore, the reset member is a first elastic member, and two ends of the first elastic member are respectively fixed to the fixing rod and the inner wall of the base.

[0010] Furthermore, the longitudinal clamping mechanism includes a cross beam, an elastic connecting member, a limit plate and a longitudinal pressure plate. The surface of the cross pressure plate is evenly distributed with a number of insertion holes from top to bottom, and the cross beam passes through the insertion holes. There are two limit plates, which are fixed to the cross beam and located between the two cross pressure plates. The longitudinal pressure plate is located below the cross beam and is fixed to the cross beam through an elastic connecting member.

[0011] Furthermore, the elastic connecting member includes an outer rod, an inner rod and a second elastic member, the outer rod and the inner rod are sleeved with each other, and the second elastic member is arranged in the inner cavity of the outer rod and contacts with the inner rod.

[0012] Furthermore, the elastic connecting member is a compression spring.

[0013] The beneficial effects of the utility model are as follows:

[0014] By turning the knob, the gear fixed coaxially with the knob can be driven to rotate. As the gear rotates, the first rack and the second rack meshing with the gear will move away from each other. At this time, the transverse pressure plate fixed by the fixing rod will move away from each other as the gear rotates. At this time, the square belt fixing can be placed between the clamping areas formed by the two transverse pressure plates. The entire fixing process only requires turning the knob and then using the elastic force of the first elastic member to reset the transverse pressure plate. Disassembly and assembly are quick and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-4As shown, a quick-disassembly and seismic-resistant bracket includes a connecting bracket 1, a base 2 and a fixing device. The base 2 has an upper opening inside for accommodating chambers. The connecting brackets 1 are in a plurality and are rotatably connected to the base 2 respectively. A mounting plate is provided at the free end of the connecting bracket 1. The fixing device includes a transverse clamping mechanism 3 and a longitudinal clamping mechanism 4. The transverse clamping mechanism 3 includes a gear 31, a first rack 32, a second rack 33, a reset member, a transverse pressing plate 36 and a knob 37. There are two transverse pressing plates 36 and they are relatively arranged on the upper part of the base 2. The gear 3 1 is rotatably connected to the inner cavity of the base 2, the first rack 32 and the second rack 33 are arranged opposite to each other with the gear 31 as the center and mesh with the first rack 32 and the second rack 33 respectively, the gear 31 and the first rack 32 are respectively fixed to the corresponding transverse pressing plate 36 through the fixing rod 34, one end of the knob 37 is coaxially fixed to the gear 31, and the other end passes through the wall of the base 2 and extends to the outside, the reset member is used to reset the fixing rod 34, and the reset member adopts the first elastic member 35, and the two ends of the first elastic member 35 are respectively fixed to the fixing rod 34 and the inner wall of the base 2.

[0025] In this embodiment, by turning the knob 37, the gear 31 coaxially fixed with the knob 37 can be driven to rotate. As the gear 31 rotates, the first rack 32 and the second rack 33 meshing with the gear 31 will move away from each other. At this time, the transverse pressure plate 36 fixed by the fixing rod 34 will move away from each other as the gear 31 rotates. At this time, the square belt fixing can be placed between the clamping area formed by the two transverse pressure plates 36. The entire fixing process only requires turning the knob 37 and then using the elastic force of the first elastic member 35 to reset the transverse pressure plate 36. Disassembly and assembly are quick and convenient.

[0026] Specifically, the longitudinal clamping mechanism 4 includes a cross beam 41, an elastic connector, a limit plate 43 and a longitudinal pressure plate 45. A plurality of insertion holes 42 are evenly distributed on the surface of the transverse pressure plate 36 from top to bottom. The cross beam 41 passes through the insertion holes 42. There are two limit plates 43, which are fixed to the cross beam 41 and are located between the two transverse pressure plates 36. The longitudinal pressure plate 45 is located below the cross beam 41 and is fixed to the cross beam 41 through an elastic connector. The elastic connector 44 includes an outer rod 46, an inner rod 47 and a second elastic member 48. The outer rod 46 and the inner rod 47 are mutually socketed. The second elastic member 48 is arranged in the inner cavity of the outer rod 46 and contacts the inner rod 47. The elastic connector adopts a compression spring.

[0027] In this embodiment, after the transverse clamping mechanism 3 is moved backward by turning the knob 37, the crossbeam 41 is inserted into the corresponding socket 42 between the transverse pressure plates 36. Since the height of the object to be fixed is not fixed, the elastic connecting member 44 is used to buffer the distance between the objects. At the same time, the crossbeam 41 is limited between the transverse pressure plates 36 by the limiting plate 43, and the longitudinal pressure plate 45 is used to limit the position of the object. Therefore, the entire installation and disassembly process only requires turning the knob 37, and then inserting the crossbeam 41 into the socket 42 between the transverse pressure plates 36. The disassembly is quick and does not require the help of connecting parts.

[0028] In summary: by turning the knob 37, the gear 31 coaxially fixed with the knob 37 can be driven to rotate. As the gear 31 rotates, the first rack 32 and the second rack 33 meshing with the gear 31 will move away from each other. At this time, the transverse pressure plate 36 fixed by the fixing rod 34 will move away from each other as the gear 31 rotates. At this time, the square belt fixing can be placed between the clamping area formed by the two transverse pressure plates 36. The entire fixing process only requires turning the knob 37 and then using the elastic force of the first elastic member 35 to reset the transverse pressure plate 36. Disassembly and assembly are quick and convenient.
