Abstract
Description
Technical Field
[0001] This invention relates to the field of pipe connection and fixing technology, specifically to a self-locking pipe clamp structure and its usage method. Background Technology
[0002] In industrial piping systems, temporary or semi-permanent fixing, connection, or support of pipes is often required. Traditional pipe clamps mostly use bolt fastening or clamp structures, which have problems such as cumbersome installation, inconvenient adjustment, insufficient locking force, or easy loosening. Especially in working conditions at height, in confined spaces, or with frequent disassembly and assembly, the operation efficiency is low and safety is difficult to guarantee.
[0003] While some existing quick-install pipe clamps offer some convenience, they lack a reliable self-locking mechanism and are prone to loosening due to vibration or external force. In addition, their simple inner lining structure cannot effectively buffer pipe stress or prevent slippage, affecting sealing performance and service life.
[0004] Therefore, there is an urgent need for a self-locking pipe clamp structure that is simple in structure, easy to operate, reliable in locking, and highly adaptable to solve the above-mentioned technical problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a self-locking pipe clamp structure and its usage method that achieves rapid closure and mechanical self-locking through handle linkage and combines adjustable hooks to adjust the tightness.
[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a self-locking pipe clamp structure, including a left clamp and a right clamp that are hinged to each other, wherein the left clamp and the right clamp are both semi-circular and form a pipe clamp ring when they are hinged together; The free end of the right clamp's outer wall is also hinged to a handle, and the outer wall of the handle is also hinged to a hook. The head of the hook forms a bent hook portion, and the outer wall of the free end of the left clamp is recessed to fit the bent hook portion and has a hook groove. When the hook part is engaged in the hook groove, the handle is rotated to lock the left and right clamps to form a pipe clamp ring.
[0007] Preferably, the outer wall of the handle is recessed with a connecting groove, a sleeve is hinged in the connecting groove, an adjusting screw ring is rotatably provided at the end of the sleeve, and the outer wall of the hook is threadedly engaged with the adjusting screw ring.
[0008] Preferably, the inner walls of both the left and right clamps are recessed with inner lining grooves, and plastic linings are engaged within the inner lining grooves.
[0009] Preferably, the inner wall of the lining groove is further provided with multiple sets of elastic clips that cooperate with the plastic lining along its circumferential direction.
[0010] Preferably, the inner wall of the handle is designed to match the curvature of the right clamp, so that when the handle is engaged with the right clamp, the inner wall of the handle abuts against the outer wall of the right clamp.
[0011] Preferably, the two side walls of the groove are formed with through holes, and knurled pins are installed in the through holes; The hook part can be engaged with the knurled pin.
[0012] Preferably, the inner wall of the plastic liner also has a wavy pattern.
[0013] Another aspect of the present invention discloses a method of using a self-locking pipe clamp structure, comprising the following steps: S1: Place the pipe to be clamped between the left and right clamps, so that the left and right clamps are in the open state; S2: Adjust the adjusting screw ring as needed to control the length of the hook. S3: Make the hook head pass over the knurled pin, press the handle down, and make the handle rotate around the hinge point with the right clamp, so that the hook moves synchronously. S4: Confirm that the hook part is stably engaged with the knurled pin and the groove. At this time, the inner wall of the handle abuts against the outer wall of the right clamp, completing the self-locking. S5: If disassembly is required, reverse the operation: lift the handle upwards to disengage the hook from the groove and knurled pin, and the left and right clamps will automatically open to remove the pipe.
[0014] The advantages of this invention compared with the prior art are as follows: In this invention, the hook position can be controlled by simply pressing the handle to complete clamping and self-locking without tools, and the hook position can be finely adjusted by adjusting the screw ring. It is compatible with various pipe diameters, and the corrugated plastic liner has both cushioning, anti-slip and sealing functions. Moreover, the liner adopts a snap-on installation, which can be quickly replaced and extends the service life of the whole machine. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] Combined with appendix Figure 1-4 As shown, a self-locking pipe clamp structure includes a left clamp 1 and a right clamp 2 that are hinged to each other. The left clamp 1 and the right clamp 2 are both semi-circular and form a pipe clamp ring when they are hinged together. The free end of the outer wall of the right clamp 2 is also hinged to a handle 3, and the outer wall of the handle 3 is also hinged to a hook 4. The head of the hook 4 forms a hook portion 5. The outer wall of the free end of the left clamp 1 is recessed with a hook groove 6 to cooperate with the hook portion 5. When the hook portion 5 is inserted into the hook groove 6, the handle 3 rotates to lock the left clamp 1 and the right clamp 2 to form a tube clamp ring.
[0022] In this invention, the outer wall of the handle 3 is recessed with a connecting groove 7, a sleeve 8 is hinged in the connecting groove 7, an adjusting screw ring 9 is rotatably provided at the end of the sleeve 8, and the outer wall of the hook 4 is threadedly engaged with the adjusting screw ring 9.
[0023] The inner walls of the left clamp 1 and the right clamp 2 are both recessed with inner lining grooves 10, and plastic inner linings 11 are engaged in the inner lining grooves 10.
[0024] The inner wall of the inner lining groove 10 is also connected with multiple sets of elastic clips 12 that are matched with the plastic inner lining 11 along its circumference.
[0025] In one embodiment: The inner wall of the handle 3 is designed to match the curvature of the right clamp 2. When the handle 3 and the right clamp 2 are engaged, the inner wall of the handle 3 abuts against the outer wall of the right clamp 2.
[0026] In one embodiment: The two side walls of the groove 6 are formed with through holes 13, and knurled pins 14 are installed in the through holes 13. The hook part 5 can be engaged with the knurled pin 14.
[0027] For sealing purposes, the inner wall of the plastic liner 11 is also formed with a wavy pattern 15.
[0028] In specific implementation, this invention includes the following steps: S1: Place the pipe to be clamped between the left clamp 1 and the right clamp 2, so that the left clamp 1 and the right clamp 2 are in the open state; S2: Adjust the adjusting screw ring 9 as needed to control the length of the hook 4. S3: Make the hook 5 of the head of the hook 4 pass over the knurled pin 14, press down the handle 3, and make the handle 3 rotate around the hinge point with the right clamp 2, so that the hook 4 moves synchronously. S4: Confirm that the hook part 5, knurled pin 14, and hook groove 6 form a stable engagement. At this time, the inner wall of the handle 3 abuts against the outer wall of the right clamp 2, completing the self-locking. S5: If disassembly is required, reverse the operation: lift the handle 3 upwards so that the hook part 5 disengages from the hook groove 6 and knurled pin 14, and the left clamp 1 and right clamp 2 automatically open, allowing the pipe to be removed.
[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0030] The working principle of this invention is as follows: the left clamp 1 and the right clamp 2 are connected at the hinge point and can rotate around that point.
[0031] When it is necessary to clamp the pipe, place the pipe between the two clamps, and rotate the handle 3 to drive the hook 4 to move, so that the hook part 5 is engaged in the hook groove 6, thereby closing and locking the left clamp 1 and the right clamp 2. It is not only easy to operate, but also provides sufficient clamping force to ensure that the pipe is firmly fixed. The handle 3 has a connecting groove 7 on its outer wall and an internal hinged sleeve 8. The hook 4 can be finely adjusted by adjusting the screw ring 9. This design allows the position of the hook 4 to be flexibly adjusted according to different pipe diameters, thereby adapting to different pipe specifications and improving the versatility and practicality of the equipment. The hook groove 6 has through holes 13 on both sides, with knurled pins 14 installed inside. The hook part 5 engages with the knurled pins 14 while being inserted into the hook groove 6, which adds an extra locking point and effectively prevents accidental loosening due to vibration or external impact, thus improving the overall safety and stability. Meanwhile, the inner walls of the left clamp 1 and right clamp 2 are provided with inner lining grooves 10 for installing the plastic inner lining 11. The corrugated texture 15 on the surface of the plastic inner lining 11 not only increases friction and prevents pipe slippage, but also provides a certain degree of sealing, protecting the pipe from the influence of the external environment. Furthermore, the design of the elastic clip 12 makes the plastic inner lining 11 easy to replace, extending the product's service life. It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
