Description

Technical Field

[0001] This utility model relates to the field of connecting bracket technology, specifically a fixed connecting bracket with shock absorption and energy dissipation function. Background Technology

[0002] The interconnection of steel structural components or parts commonly uses welded connections, bolted connections, or riveted connections. Bolted connections are further divided into ordinary bolted connections and high-strength bolted connections. Ordinary bolted connections were the earliest to be used, starting around the mid-18th century. Riveted connections began to be used in the 1820s, and welded connections appeared in the second half of the 19th century. Since the mid-20th century, high-strength bolted connections have been developed and are now part of the current technology.

[0003] CN210658986U discloses a fixing connection component for building supports, including a support. The left inner wall of the support has a slot, the outer wall of which is connected to the inner wall of the support. A snap plate is installed on the left outer wall of the support. The inner wall of the snap plate has a groove, and the inner wall of the groove has a protrusion. The outer wall of the protrusion slidably engages with the inner wall of the groove. This fixing connection component for building supports, through the cooperation of the snap plate, protrusion, support, and slot, and under the action of the insert rod and clamping plate, allows the protrusion and snap plate to engage with each other, enabling quick installation and disassembly of the support to the building wall. The insert rod can drive the clamping plate to be installed in the slot inside the support. The top plate and groove are tightly engaged, thereby improving the stability between the clamping plate and the support, preventing poor contact between the support rod and the support. The support rod sways left and right inside the clamping plate, improving overall safety, making it suitable for widespread use. However, the aforementioned building support fixed connection components have a relatively simple structure and are not easy to adjust the hole spacing of the connection position during connection and assembly. They are not easy to adapt to different connection positions and require connection holes with corresponding spacing for assembly, which makes the overall device less adaptable. At the same time, after assembly, the connection components are easily affected by vibration during the main operation process, which can easily cause them to loosen and fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed connection bracket with shock absorption and energy dissipation function, which has a wide range of applications, good connection performance, and the advantages of stable installation with shock absorption and energy dissipation.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A fixed connection bracket with shock absorption and energy dissipation function includes:

[0007] A base plate, a top plate, and two sleeves fixed to the top of the base plate. The two sleeves are arranged at left and right intervals, and a sliding rod is fitted inside each of the two sleeves.

[0008] The top plate is fixed to the top of the two sliding rods. The top of the top plate is provided with two sliding grooves spaced apart from each other. The sliding grooves extend in the left and right direction, and a connecting frame is slidably installed in the sliding grooves.

[0009] The top plate is rotatably connected to a bi-directional threaded rod extending to the left and right. One end of the bi-directional threaded rod extends out of the top plate and is connected to a turntable. A threaded block is fixedly connected to the bottom of the connecting frame. The threaded block is threadedly engaged with the bi-directional threaded rod.

[0010] A crossbar is fixed to the top of the base plate, and two connecting rods are rotatably connected to the bottom of the top plate. A sliding sleeve is rotatably connected to the bottom of the connecting rod, and the sliding sleeve slides with the crossbar. A return spring is sleeved on the outside of the crossbar.

[0011] Mounting plates are fixed on both the left and right sides of the base plate. Screws are screwed onto the mounting plates, and limiting springs are sleeved on the outside of the screws.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. Through the cooperation of the bidirectional threaded rod and the turntable, the two threaded blocks move along the bidirectional threaded rod in opposite or opposite directions. At the same time, the two threaded blocks will drive the two connecting frames to move closer or further away from each other, so that the two connecting frames can connect the main body with holes of different spacing, improving the convenience and adaptability of the assembly process.

[0014] 2. By setting screws and mounting plates, not only is it convenient to fix the overall device, but the elastic force of the limit spring can also act in the opposite direction on the screws, so that the screws will not easily loosen or fall off after being tightened and installed, thus improving the stability of the overall device.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0022] like Figure 1-5 The diagram shown is a schematic representation of an embodiment of a fixed connection bracket with shock absorption and energy dissipation function provided by this utility model:

[0023] A fixed connection bracket with shock absorption and energy dissipation function includes:

[0024] The base plate 1, the top plate 4, and two sleeves 2 fixed on the top of the base plate 1 are arranged at left and right intervals, and a sliding rod 3 is sleeved inside each of the two sleeves 2.

[0025] The top plate 4 is fixed on the top of the two sliding rods 3. The top of the top plate 4 is provided with two sliding grooves 17 that are spaced apart from each other. The sliding grooves 17 extend in the left and right direction, and a connecting frame 8 is slidably provided in the sliding grooves 17.

[0026] The top plate 4 is rotatably connected to a bidirectional threaded rod 18 extending to the left and right. One end of the bidirectional threaded rod 18 extends out of the top plate 4 and is connected to a turntable 20. The bottom of the connecting frame 8 is fixedly connected to a threaded block 19, which is threadedly engaged with the bidirectional threaded rod 18.

[0027] The top of the base plate 1 is also fixed with a crossbar 5, and the bottom of the top plate 4 is rotatably connected with two connecting rods 7. The bottom of the connecting rods 7 is rotatably connected with a sliding sleeve 6. The sliding sleeve 6 is slidably engaged with the crossbar 5, and a return spring 11 is sleeved on the outside of the crossbar 5.

[0028] Mounting plates 9 are fixed on both the left and right sides of the base plate 1. Screws 14 are screwed onto the mounting plates 9, and limiting springs 15 are sleeved on the outside of the screws 14.

[0029] Specifically, when connecting the overall device to the main body, by rotating the turntable 20 and the bidirectional threaded rod 18, the two threaded blocks 19 are displaced along the bidirectional threaded rod 18 in opposite or opposite directions. At the same time, the two threaded blocks 19 will drive the two connecting brackets 8 to move closer or further away from each other, so that the two connecting brackets 8 can connect the main body with holes of different spacing, improving the convenience and adaptability of the assembly process. When installing the overall device, the screws 14 and the mounting plate 9 can be used to fix the overall device. At the same time, the elastic force of the limiting spring 15 can act on the screws 14 in the opposite direction, so that the screws 14 will not easily loosen or fall off after being tightened and installed, thus improving the stability of the overall device.

[0030] A damping plate 13 is fixedly provided at the bottom of the slide rod 3. The damping plate 13 slides in conjunction with the inner wall of the sleeve 2. A buffer spring 12 is installed between the bottom side of the damping plate 13 and the bottom of the sleeve 2.

[0031] The two sliding sleeves 6 are located at the two ends of the return spring 11, respectively.

[0032] Through the sliding friction between the damping plate 13 and the inner wall of the sleeve 2, and the elastic force of the buffer spring 12, the top plate 4 can simultaneously have a shock-absorbing and buffering effect when the sliding rod 3 slides and rises and falls inside the sleeve 2.

[0033] A buffer pad 10 is also provided between the end of the sliding sleeve 6 and the return spring 11. The buffer pad 10 is sleeved on the crossbar 5. The two buffer pads 10 can help improve the energy dissipation effect and at the same time play a protective role between the sliding sleeve 6 and the return spring 11.

[0034] The bottom of the base plate 1 is fixedly connected with several ribs 16, which are arranged at left and right intervals, and the ribs 16 are made of rubber.

[0035] The rib 16 can increase the friction between the base plate 1 and the mounting surface, thereby improving the stability after installation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
