Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of suspension pipe clamp, in particular to an adjustable suspension pipe clamp. BACKGROUND

[0002] In modern construction and industrial equipment installation, the pipeline system is an indispensable part. In order to ensure the safety, stability and efficient operation of the pipeline, various types of pipe clamps are widely used to fix and support the pipeline. The traditional suspension pipe clamp is usually fixed by bolt hoop. Although this design can provide strong fixing force, there are some obvious shortcomings in the actual installation and use process.

[0003] The traditional bolt hoop fixing method requires workers to manually tighten the bolts, which is not only time-consuming and laborious, but also particularly inconvenient in narrow or difficult-to-reach spaces. Since the bolts need to be accurately aligned and tightened, any slight error in the installation process may cause the pipe clamp to be not fixed firmly, affecting the overall stability of the pipeline system. In addition, the traditional bolt hoop fixing method is particularly inconvenient when adjustment is needed. Once the pipeline is installed, if fine adjustment or repositioning is needed, the bolts must be loosened, adjusted and then tightened again. This process is not only tedious, but also easy to cause wear and tear of the bolts and hoop, reducing their service life. Therefore, an adjustable suspension pipe clamp is needed to solve the above problems. SUMMARY

[0004] The purpose of the present application is to solve the problems raised in the background.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme: An adjustable suspension pipe clamp, comprising, An upper hoop ring group, the upper hoop ring group comprises an upper ring buckle, two movable discs are connected to the right side of the upper ring buckle, a lower buckle ring group is movably installed between the two movable discs through a connecting piece, and a clamping hook block is connected to the left side of the upper ring buckle; The lower buckle ring group comprises a movable cylinder placed between the two movable discs, a reinforcing ring plate is connected to the bottom end of the movable cylinder, a buckle plate is connected to the surface of the reinforcing ring plate through a reed support plate, a side connecting plate is connected to the left side of the buckle plate, and a toothed arc plate is arranged on the surface of the side connecting plate, the tooth groove spacing of the toothed arc plate is 5mm, the tooth depth is 3mm, and the inclination angle of the arc-shaped baffle is 15°, so as to ensure that the clamping hook block is prevented from being unlocked. A hoisting component, the hoisting component comprises a hoisting inner cylinder fixedly connected with the top end of the upper ring buckle, a sleeve is sleeved on the surface of the hoisting inner cylinder, and a hoisting disc is connected to the top end of the sleeve, and the hoisting inner cylinder and the sleeve are designed to be telescopic, so as to position and adjust the upper ring buckle.

[0006] Preferably, the hook block side is provided with a hook plate end, a plurality of tooth grooves are equidistantly arranged on the surface of the tooth arc plate, and an inner clamping plate adapted to the hook plate end of the hook block is arranged in the tooth groove. When the side connecting plate moves with the rotating of the buckle ring plate, the side connecting plate can drive the tooth arc plate to abut against the hook block. Through the clamping of the hook block and the inner tooth groove of the tooth arc plate, the clamping effect of the upper ring buckle and the reinforcing ring plate on the pipeline can be ensured.

[0007] Preferably, the adapter includes a threaded shaft penetrating between the movable disc and the movable cylinder, one side of the movable disc is provided with an inner groove, the threaded shaft is threadedly sleeved with a nut, and the nut is attached to the side of the movable disc.

The upper and lower ends of the reed support plate are respectively connected and fixed with the inner end faces of the buckle ring plate and the reinforcing ring plate. The V-shaped structure of the reed support plate can conveniently provide elastic support for the buckle ring plate. The reinforcing ring plate and the buckle ring plate cooperate to increase the supporting force and improve the supporting strength of the buckle ring plate, preventing irreversible deformation of the buckle ring plate due to external force pulling.

[0010] Preferably, a plurality of rubber strips are equidistantly arranged on the top surface of the buckle ring plate, and the length of the rubber strip is adapted to the width of the nut. The height design of the rubber strip can conveniently support the pipeline during the buckling process.

[0011] Preferably, the tooth arc plate tooth groove is provided with arc-shaped baffle ends on both sides, and the width of the tooth groove of the tooth arc plate is adapted to the length of the hook block.

The tooth groove clamping design of the hook block and the toothed arc plate replaces the traditional bolt fastening mode, realizes quick locking and unlocking of the pipeline, combines the elastic support of the V-shaped spring plate, and enables the lower clamping ring group to be self-adaptive to different pipe diameters, thereby significantly reducing the installation time and manual operation strength, and being especially suitable for narrow spaces.

[0015] 2. The lifting part adopts a telescopic structure, the lifting inner cylinder and the sleeve are controlled to lift and lower through adjusting bolts, and stable movement is guided by the limiting blocks, so that the pipeline suspension height can be accurately fine-tuned, different installation environments can be adapted without disassembling the pipe clamp, and for example, the height of the ceiling fluctuates.
