Description

Technical Field

[0001] This utility model relates to the technical field of pipe clamps, and in particular to a new type of adjustable quick-release hanging clamp. Background Technology

[0002] Traditional pipe clamps are mostly composed of two semi-circular components, commonly including the following types: 1. Two semi-circular metal frames lined with plastic pads, each with protruding connecting plates at both ends. The two connecting plates are connected by bolts, and one of the semi-circular metal frames is then threaded onto a lifting bolt. 2. Two interlocking arc-shaped metal clamps, with the other ends connected by bolts. One end of the bolts is threaded onto the lifting bolt, or one of the arc-shaped clamps is threaded onto the lifting bolt. 3. A U-shaped double-ended bolt with a separate buffer foam block forming a central cavity fitted around it. This block is then connected to the lifting structure after the pipe is installed. 4. Adjustable pipe clamps are made of plastic and include an arc-shaped base connecting to the lifting rod. The arc-shaped base is hinged to an arc-shaped movable clamp, the free end of which has serrations that fit the arc-shaped base. Although adjustable, these clamps have low reliability in securing the pipe and are prone to accidental release.

[0003] All of the aforementioned hoisting shackles are time-consuming and labor-intensive to install, resulting in low construction efficiency, high construction costs, and inconsistent manufacturing quality. They have become a significant factor affecting pipeline installation schedules and cost control. Therefore, how to improve on-site pipeline installation efficiency and reduce construction costs while ensuring construction quality has become an urgent problem to be solved in project management.

[0004] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a novel adjustable snap-on lifting clamp, aiming to solve the technical problem of improving the installation efficiency and reliability of pipe hoisting.

[0006] The technical solution of this utility model is as follows: An adjustable snap-on hanging clip includes an arc-shaped body made of rigid elastic plastic. The first end of the arc-shaped body is provided with several slots inclined in a first direction, and the second end is provided with at least one tooth inclined in a second direction. An elastic pressure arm is provided on the outer side of the second end to press the slots against the tooth.

[0007] Based on the above technical solutions, as a preferred technical solution for a new type of adjustable instant-fastening lifting clamp, the arc-shaped main body is connected to a protruding connecting block, and the connecting block is provided with a connecting hole for the lifting screw to pass through.

[0008] Based on the above technical solutions, as a preferred technical solution for the new adjustable quick-release hanging clamp, the connecting block is provided with at least two, and the connecting holes on the two connecting blocks are arranged coaxially.

[0009] Based on the above technical solutions, as a preferred technical solution for the new adjustable quick-release hanging clamp, the connecting hole is a non-closed hole, with a side opening on the left side of the connecting hole on one of the connecting blocks and a side opening on the right side of the connecting hole on the other connecting block.

[0010] Based on the above technical solutions, as a preferred technical solution for the new adjustable snap-on hanging clamp, the axis of the connecting hole is perpendicular to the axis of the circular clamp formed by connecting the two ends of the arc-shaped body.

[0011] Based on the above technical solution, as a preferred technical solution for a new type of adjustable snap-on hanging clamp, the arc-shaped body is provided with several prestressed grooves at the position between the first end and the second end.

[0012] Based on the above technical solutions, as a preferred technical solution for the new adjustable snap-on hanging clamp, when one prestressed groove is provided, the prestressed groove is located in the middle position of the arc-shaped body.

[0013] Based on the above technical solutions, as a preferred technical solution for the new adjustable snap-on hanging clamp, the prestressed groove is arranged along the width direction of the arc-shaped body, and the axis of the prestressed groove is parallel to the axis of the circular clamp.

[0014] Based on the above technical solution, as a preferred technical solution for the new adjustable snap-on hanging clamp, the connection position between the elastic pressure arm and the arc-shaped body is a forked position, the length of the elastic pressure arm is greater than the distance between the locking teeth and the forked position, the width of the elastic pressure arm is greater than the width of the first end, and positioning protrusions for limiting the first end are provided on both sides of the elastic pressure arm.

[0015] Based on the above technical solutions, as a preferred technical solution for a new type of adjustable snap-on hanging clamp, the first end is connected to the arc-shaped body through an outwardly extending bending structure, and the second end forms a slot with the elastic pressure arm to clamp the first end.

[0016] This invention provides a novel adjustable snap-on pipe clamp. Compared to traditional pipe clamps, it features a single, integrally molded arc-shaped body with matching slots and teeth at both ends. During use, the arc-shaped body only needs slight bending to engage the slots, forming a circular clamp. Because the arc-shaped body is integrally injection-molded from rigid, elastic plastic, it possesses internal stress, preventing the ends from detaching and ensuring a tighter clamping effect. Furthermore, this invention includes an elastic pressure arm, which not only presses the interlocking teeth and slots together but also provides protection, preventing the second end with the slot from detaching from the first end's teeth due to external impact. The first end with the teeth remains firmly against the pipe's outer wall and will not actively or passively detach from the second end's slot. Therefore, the technical solution provided by this invention improves both the installation efficiency and reliability of pipe hoisting. Attached Figure Description

[0025] All terms used in this application have the same meaning as understood by one of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] An adjustable snap-on hanging clip, such as Figure 4 As shown, the system includes an arc-shaped main body 1 made of rigid elastic plastic. The arc-shaped main body 1 is integrally molded by injection molding and has its own elasticity. In its natural state, it is arc-shaped as a whole. When assembled, the two ends are connected to form a ring.

[0028] The first end 11 of the arc-shaped body 1 is provided with a plurality of slots 111 inclined in a first direction, and the second end 12 is provided with at least one tooth 121 inclined in a second direction. The slots 111 and the tooth 121 are adapted to each other. During assembly, the first end 11 and the second end 12 are connected by the tooth 121 adapting to the slots 111, so that the entire arc-shaped body 1 forms a ring. When the tooth 121 adapts to different slots 111, the size of the ring can be adjusted, thus making it suitable for clamping pipes of different diameters.

[0029] It should be noted that when the ends of the arc-shaped body 1 are not connected, the first direction is inclined toward the inside of the first end 11, which is equivalent to a barb structure, and the second direction is inclined toward the inside of the second end 12, which is also equivalent to a barb structure; when the ends of the arc-shaped body 1 are connected, the locking teeth 121 and the locking groove 111 form a mutually compatible hook structure.

[0030] Furthermore, an elastic pressure arm 13 is provided on the outer side of the second end 12 to press the slot 111 against the tooth 121. That is, another end is provided on the outer side of the second end 12. This end is integrally formed with the arc-shaped body 1 and arranged parallel to the second end 12, thereby forming a gap to accommodate the first end 11. When the arc-shaped body 1 is connected end to end, the first end 11 is clamped between the second end 12 and the elastic pressure arm 13. For the first end 11, its inner side is supported by the second end, and its outer side is covered by the elastic pressure arm 13. Since the second end 12 is close to the pipe being hoisted, and the elastic pressure arm 13 has a tendency to press against the second end 12, the first end 11 can be firmly clamped between the two, thereby fully ensuring the reliability of the connection between the tooth 121 and the slot 111.

[0031] Based on the above embodiments, as a preferred embodiment of the novel adjustable instant-fastening hanging clamp, such as... Figures 1 to 3 As shown, the arc-shaped main body 1 is connected to a protruding connecting block 14, and the connecting block 14 is provided with a connecting hole 141 for the lifting screw 2 to pass through. This embodiment provides a preferred structural form for connecting the lifting screw 2, that is, a connecting block 14 with a connecting hole 141 is provided on the outer side of the arc-shaped main body 1. Preferably, the connecting block 14 and the arc-shaped main body 1 are integrally injection molded.

[0032] Preferably, the lifting screw 2 is a traditional threaded screw, with its upper end fixed to the ceiling via an expansion five-piece set 3. The expansion five-piece set 3 is a mature, existing standard component, comprising: an expansion head for fixing to the wall or concrete, achieving stability through expansion; an expansion tube for use with the expansion head to form a fixed structure; a washer to prevent the screw from loosening and protect the threads; a spring washer to increase friction and prevent the nut from loosening; and a nut to secure the screw and prevent loosening. The lower end of the lifting screw 2 passes through the connecting hole 141 and is connected to a fastening nut, which is supported below the connecting block 14.

[0033] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on hanging clamp, at least two connecting blocks 14 are provided, and the connecting holes 141 on the two connecting blocks 14 are arranged coaxially. This embodiment provides a preferred arrangement of the connecting blocks 14. By increasing the number of connecting blocks 14, the connection between the arc-shaped body 1 and the lifting screw 2 can be made more stable and secure.

[0034] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on hanging clamp, the connecting hole 141 is a non-closed hole. One connecting block 14 has a side opening on the left side of its connecting hole 141, and the other connecting block 14 has a side opening on the right side of its connecting hole 141. This embodiment provides a preferred structural design for the connecting hole 141, designing it as a non-closed structure, allowing the lifting screw 2 to enter the connecting hole 141 through the side opening, further improving assembly convenience. It should be noted that the side opening of the connecting hole 141 is smaller than the diameter of the lifting screw 2, allowing the lifting screw 2 to enter the connecting hole 141 through strong pressure, and preventing the lifting screw 2 from coming out of the side opening of the connecting hole 141.

[0035] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on lifting clamp, the axis of the connecting hole 141 is perpendicular to the axis of the circular clamp formed by connecting the two ends of the arc-shaped body 1. That is, the pipe to be lifted is horizontally arranged, while the lifting screw 2 is vertically arranged. The axis of the circular clamp formed by the arc-shaped body 1 is perpendicular to the axis of the connecting hole 141, which can better adapt to the application conditions and avoid generating torque that affects the service life.

[0036] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on hanging clamp, the arc-shaped body 1 is provided with a plurality of prestressed grooves 15 at the position between the first end 11 and the second end 12. Preferably, the prestressed grooves 15 are arc-shaped grooves and are concave inward toward the center of the arc-shaped body 1. When the first end 11 and the second end 12 of the arc-shaped body 1 are connected to the locking teeth 121 through the locking groove 111, the prestressed grooves 15 can provide stress for the relative separation of the first end 11 and the second end 12, thereby making the connection between the locking teeth 111 and the locking teeth 121 more secure.

[0037] Based on the above embodiments, as a preferred embodiment of the new adjustable snap-on hanging clamp, when one prestressed groove 15 is provided, the prestressed groove 15 is located in the middle position of the arc-shaped body 1, which is convenient for injection molding and assembly operation.

[0038] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on hanging clamp, the prestressed groove 15 is arranged along the width direction of the arc-shaped main body 1, and the axis of the prestressed groove 15 is parallel to the axis of the circular clamp. Preferably, the diameter of the ring formed after the arc-shaped main body 1 is connected end to end is denoted as A, and the diameter of the prestressed groove 15 is denoted as B, then B is one-twentieth to one-fifteenth of A.

[0039] Based on the above embodiments, as a preferred embodiment of the new adjustable snap-on hanging clip, the connection position between the elastic pressure arm 13 and the arc-shaped body 1 is the bifurcation position 131. The length of the elastic pressure arm 13 is greater than the distance between the locking tooth 121 and the bifurcation position 131. Therefore, when the arc-shaped body 1 is connected end to end, the elastic pressure arm 13 can cover more parts of the first end 11.

[0040] The width of the elastic pressure arm 13 is greater than the width of the first end 11, and positioning protrusions for limiting the first end 11 are provided on both sides of the elastic pressure arm 13. The matching of the slot 111 and the tooth 121 is used to limit the diameter of the arc-shaped body 1 after it is formed into a ring. The second end 12 and the elastic pressure arm 13 limit the position of the first end 11 from the inner and outer sides in the radial direction, respectively, while the positioning protrusions can limit the position of the first end 11 from the axial direction, which fully ensures the reliability of the connection between the tooth 121 and the slot 111.

[0041] Based on the above embodiments, as a preferred embodiment of the novel adjustable snap-on hanging clip, the first end 11 and the arc-shaped body 1 are connected by an outwardly extending bending structure 112. The inner wall of the arc-shaped body 1 after forming a ring can form a regular circle. The second end 12 and the elastic pressure arm 13 form a slot to better clamp the first end 11.

[0042] Finally, it should be noted that the parts not described in detail in the above embodiments are all common knowledge known to those skilled in the art.

[0043] The above content shows and describes the basic principles, main features, and beneficial effects of this utility model. The above description is merely a preferred embodiment of this utility model and is not intended to limit it. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
