[0002] During the construction process of a project or a temporarily used support platform, a steel pipe support is usually built with steel pipes, which is not only fast to build but also has good economic and social value. A fastener is a connecting part used to connect steel pipes. The existing fasteners generally consist of two split fasteners, which are riveted together and can rotate at any angle. Each of the two split fasteners is provided with two clamping plates, and then the two ends of the two clamping plates are fixed by bolts. The steel pipe is clamped between the two clamping plates. During installation, it is necessary to first clamp the two clamping plates of the split fastener on the steel pipe, and then tighten the bolts at both ends to clamp the steel pipe; however, this type of fastener structure is time-consuming and laborious when connecting and installing steel pipes, and the clamping degree of the steel pipe depends on the tightening degree of the bolts, which is easy to loosen over time. Moreover, since the fastening method uses bolts fixed at both ends, it is very inconvenient to make fine adjustments to the position during the building process. It is necessary to loosen the bolts, adjust them, and then fix them again.

[0003] Through the above analysis, the problems and defects existing in the prior art are as follows:

[0004] When the existing fastener structure is used to connect and install steel pipes and make adjustments, it is time-consuming and laborious, and it is easy to loosen over time. Moreover, the operation process is cumbersome when making fine adjustments to the position of the steel pipe during the building process. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the utility model provides a steel pipe rack fastener which is convenient for installation and disassembly. The steel pipe rack fastener which is convenient for installation and disassembly includes two clamping components. Each clamping component is provided with a base and a clamping plate. One end of the clamping plate is axially connected to one end of the base by a bolt, and the other end of the clamping plate is loosely connected to the other end of the base by a connecting piece;

[0006] The bases of the two clamping components are connected to each other;

[0007] One end of the connecting piece is axially connected with a locking piece, and the other end of the connecting piece is provided with a blocking piece. One end of the locking piece connected to the connecting piece is provided with a supporting part. When the locking piece rotates towards the direction close to the clamping plate, the connecting piece can be jacked up upwards by the supporting part and the clamping plate can be pressed tightly.

[0008] Preferably, the bases of the two clamping components are connected by a shaft, and both clamping components can rotate around the shaft.

[0009] Preferably, the bases of the two clamping components are fixedly connected to each other in a cross shape.

[0010] Preferably, a screw is provided at the end of the locking member, and a threaded hole is provided on the clamping plate.

[0016] Combining all the above technical solutions, the advantages and positive effects of the present invention are as follows:

[0017] The steel pipe rack fastener provided by the present utility model is convenient for installation and disassembly. One end of the base and the clamping plate of the clamping assembly is axially connected, so that the clamping plate can rotate and open and close. The other end is loosely connected by a connecting member. The head of the connecting member is axially connected with a quick locking member. The quick locking member adopts the lever principle. When the locking member is pressed, with the support portion of the locking member as the fulcrum, the connecting member is lifted upward while the clamping plate is pressed, so as to achieve the purpose of quickly locking the steel pipe. During installation, it is not only convenient to operate, time-saving and labor-saving, but also very convenient to adjust the position of the steel pipe during the erection process. Moreover, this locking method is more stable. Since the locking method does not lock through bolts and nuts, the situation of the steel pipe slipping due to the loosening of the bolts will not occur.

Specific embodiments

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Refer to Figures 1 to 4 As shown, a steel pipe rack fastener that is convenient for installation and disassembly provided by this embodiment includes two clamping assemblies 100. The clamping assembly 100 includes a base 1 and a clamping plate 2. Both the clamping plate 2 and the base 1 are provided with semi-circular grooves 12. One end of the clamping plate 2 and one end of the base 1 are axially connected by a bolt 6, so that the clamping plate 2 can rotate and open around the axis of the bolt 6. A notch 21 is provided at the other end of the clamping plate 2, and a fixing hole 11 is provided at the other end of the base 1. The connecting member 3 passes through the notch 21 of the clamping plate and the fixing hole 11 of the base 1 in sequence, and a thread is provided at the tail of the connecting member 3 and a blocking member 31 is installed. The blocking member selected in the embodiment of the present application is a nut, which plays a role of limiting and blocking, and finally the other end of the clamping plate 2 and the other end of the base 1 are loosely connected by the connecting member 3; A locking member 4 is axially connected to the head of the connecting member 3. Specifically, a shaft hole 32 is provided at the head of the connecting member 3, a U-shaped notch 41 is provided at one end of the locking member 4, through holes 42 are provided on both side walls of the U-shaped notch 41 of the locking member 4. The U-shaped notch 41 of the locking member 4 is clamped on the head of the connecting member 3, and a pin shaft passes through the through holes 42 on both side walls of the U-shaped notch 41 and the shaft hole 32 at the head of the connecting member, and finally realizes the axial connection between the head of the connecting member 3 and the locking member 4;

[0027] Two clamping components 100 are integrally connected through the mutual connection of their bases 1. In an alternative embodiment, the bases 1 of the two clamping components 100 can be connected by a pin shaft 5. This connection method enables both of the two clamping components 100 to rotate relative to each other at any angle perpendicular to the axis around the pin shaft 5. Thus, the angle adjustment between the two clamping components 100 during installation is more flexible; as Figure 5 shown, in another alternative embodiment, the bases 1 of the two clamping components 100 are fixedly connected to each other in a cross shape, and welding can be used for fixation. Although this embodiment cannot adjust the angle between the two clamping components 100, due to the connection method being welding, it is more stable during the cross connection between steel pipes;

[0028] In order to use the lever principle to enable the locking member 4 to close and lock the clamping component, a support portion 43 is provided at one end of the locking member 4 connected to the connecting member 3. Specifically, the outer peripheries of the two side walls of the U-shaped notch 41 of the locking member 4 are designed to be arc-shaped, and the center of the arc is concentric with the through holes 42 on the two side walls of the U-shaped notch 41. Thus, the arc-shaped outer wall at the outer end of the locking member 4 forms the support portion 43. When the locking member 4 is rotated in the direction close to the clamping plate, with the arc-shaped outer wall as the support portion 43, the head of the connecting member 3 can be jacked up and the clamping plate 2 can be pressed tightly through the support portion 43. In this way, the connecting member 3 drives the nut at the tail to tightly press against the base 1, and at the same time, the support portion 43 of the locking member 4 presses tightly against the clamping plate 2, thereby achieving the purpose of finally locking the clamping plate;

[0029] In order to make the rotation angle of the locking member 4 sufficient for locking, the locking member 4 is integrally in an arc-shaped structure. And when the locking member 4 locks the clamping component 100, the locking member 4 can fit with the outer wall of the clamping plate 2. At the same time, the contact point between the arc-shaped outer wall and the clamping plate 2 and the center of the arc-shaped outer wall are on the same vertical center line, ensuring that the tension of the clamping plate 2 on the arc-shaped outer wall is vertically upward. In this way, it can be ensured that the locking member 4 will not bounce open by itself without external force when in the locked state; and this locking method uses the principle of lever jacking for locking, and the locking method is more stable and will not become loose;

[0030] In a preferred embodiment, in order to prevent the locking member 4 from opening under the influence of external environmental factors, a screw 7 can also be provided at the end of the locking member 4, and a threaded hole 22 is provided on the clamping plate. It can be achieved by manually screwing the screw into the threaded hole 22 to prevent the locking member 4 from opening under the influence of the external environment.

[0031] The following describes the steel pipe rack fastener that is convenient for installation and disassembly of the present application in combination with the specific use process:

[0032] During the construction of the steel pipe support, the connection between two steel pipes is required. First, any clamping component 100 in the fastener is clamped on one steel pipe, and then the locking member 4 is manually rotated to lock the clamping component 100 so that the clamping component 100 clamps the steel pipe. Then, the other clamping component 100 in the fastener is clamped on the steel pipe to be connected. Similarly, the locking member 4 is manually rotated for locking. In this way, the prototype of the steel pipe rack can be quickly and labor-savingly constructed. Then, check whether the installed steel pipes are vertical or parallel. If any deviation is found, the locking member 4 of the corresponding clamping component 100 on the steel pipe can be loosened to release the locking, and the position can be finely adjusted in time. Finally, after it is determined that the overall construction between the steel pipes is qualified, in order to prevent the locking member from being opened due to external environmental factors, screws 7 can be manually screwed into the ends of the locking members of all clamping components 100 uniformly to fix the ends of the locking member 4.
