Description

Technical Field

[0001] This application relates to the technical field of plastic part fixtures, and particularly to a circular plastic pipe fixture with high stability. Background Art

[0002] Plastic materials have good corrosion resistance and can be used as pipes to transport liquids. The pipes used for slope drainage need to have holes drilled on the side of circular plastic pipes. The circular plastic pipes are fixed with fixtures, and then drilling equipment is used to drill holes.

[0003] Plastic pipes are flexible by themselves. When using fixtures for clamping and fixing, the clamping force generated by the fixtures will cause the plastic pipes to deform, and then the clamping of the circular plastic pipes is unstable, affecting subsequent hole processing. Therefore, the utility model provides a circular plastic pipe fixture with high stability. Summary of the Invention

[0004] The purpose of this application is to provide a circular plastic pipe fixture with high stability to avoid the instability of circular plastic pipes during the hole-opening process.

[0005] To achieve the above purpose, the technical solution adopted in this application is as follows:

[0006] A circular plastic pipe fixture with high stability, comprising:

[0007] A base, on the top of which there is an arc-shaped opening;

[0008] The bottom of the base is fixedly installed with a bidirectional telescopic member through a connecting frame. The two telescopic ends of the bidirectional telescopic member are respectively located at both ends of the base, and inverted "L" clamping members are fixedly installed at the two telescopic ends of the bidirectional telescopic member. The horizontal part of the inverted "L" clamping member and the inner side of the arc-shaped opening form a clamping area.

[0009] As a preference, a long groove is opened at the inner bottom of the arc-shaped opening, and a cylinder is arranged inside the long groove. The length of the cylinder is shorter than the length of the long groove;

[0010] A through hole is opened at the inner bottom of the long groove, and a centering structure is arranged between the cylinder and the base.

[0011] As a preference, elastic pads are fixedly connected to both ends of the inner side of the arc-shaped opening and located at the positions of the base.

[0012] As a preference, the centering structure includes:

[0013] Two groups of laterally distributed side ears are fixedly arranged at the bottom of the cylinder and inside the through hole;

[0014] On both sides of the pleurotus, a first connecting rod and a second connecting rod are respectively arranged. A shaft member is fixedly connected between the first connecting rod and the second connecting rod, and the shaft member is fixedly connected to the pleurotus.

[0015] The first connecting rod and the second connecting rod are located on both sides of the connecting frame, and a second elastic member is arranged between the first connecting rod and the connecting frame, and a first elastic member is arranged between the second connecting rod and the connecting frame.

[0016] As a preference, two groups of the long grooves and the cylinders are provided.

[0017] As a preference, guiding wing members are fixedly installed on the outer side of the base. There are two groups of the guiding wing members, and the two groups of guiding wing members are distributed on both sides of the base.

[0018] As a preference, the base is of a shell structure.

[0019] As a preference, a rectangular opening is formed at the bottom of the base, and the telescopic shaft of the bidirectional telescopic member is located inside the rectangular opening.

[0020] As a preference, an inclined opening is arranged below the horizontal part of the inverted "L" clamping member.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] (1) In this utility model, by designing the base and using the bidirectional telescopic member to drive the inverted "L" clamping member, a clamping area is formed between the horizontal part of the inverted "L" clamping member and the inner side of the arc-shaped opening. In this way, the side wall of the end of the circular plastic pipe can be clamped and fixed, and the side wall of the end of the circular plastic pipe can be clamped and fixed without deforming the circular plastic pipe, thereby realizing the stable fixation of the circular plastic pipe and ensuring the stability during the subsequent processing of the circular plastic pipe.

[0023] (2) In this utility model, by designing the long groove, the cylinder is slidably arranged inside the long groove, and a centering structure is designed to keep the cylinder elastically at the middle position of the long groove. When in use, the circular plastic pipe presses on the cylinder, and the cylinder can axially slide together with the circular plastic pipe. After the circular plastic pipe is disassembled, the centering structure makes the cylinder automatically return to the center, ensuring that when the circular plastic pipe is placed on the next side, the circular plastic pipe can axially slide towards both ends.

[0032] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that for orientation terms, if there are terms such as "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship are based on the orientation or position relationship shown in the drawings, and are only for facilitating the description of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0035] The terms "comprising" and "having" in the description and claims of this application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0036] As Figures 1-7 shown in the highly stable circular plastic pipe clamp, which includes: a base 1, an arc-shaped opening 1a is provided at the top of the base 1, and the shape of the arc-shaped opening 1a matches the outer side of the circular plastic pipe, so that the circular plastic pipe can be stably placed in the arc-shaped opening 1a of the base 1. A two-way telescopic member 14 is fixedly installed at the bottom of the base 1 through a connecting frame 11. The two telescopic ends of the two-way telescopic member 14 are respectively located at both ends of the base 1, and inverted "L" clamping members 15 are fixedly installed at the two telescopic ends of the two-way telescopic member 14. The horizontal part of the inverted "L" clamping member 15 and the inner side of the arc-shaped opening 1a form a clamping area.

[0037] When in use, place the circular plastic pipe 3 into the arc-shaped opening 1a of the base 1, and then control the two-way telescopic member 14 to contract, so that the two inverted "L" clamping members 15 move synchronously towards the circular plastic pipe 3. The two-way telescopic member 14 first pushes the circular plastic pipe 3 to the middle of the base 1, and then the two inverted "L" clamping members 15 cooperate with the inner side of the arc-shaped opening 1a to fix the circular plastic pipe 3 from both ends of the circular plastic pipe 3.

[0038] In one embodiment, a long groove 2 is provided at the inner bottom of the arc-shaped opening 1a, a cylinder 4 is arranged inside the long groove 2, and the length of the cylinder 4 is shorter than the length of the long groove 2, so that the cylinder 4 can axially slide inside the long groove 2. A through hole 6 is provided at the inner bottom of the long groove 2, and a centering structure is arranged between the cylinder 4 and the base 1. When the cylinder 4 is not subject to external force, the centering structure pushes the cylinder 4 back to the middle position of the long groove 2.

[0039] When in use, the circular plastic pipe 3 presses on the cylinder 4. Since the cylinder 4 can axially slide inside the long groove 2, the circular plastic pipe 3 can slide axially more easily, so as to facilitate moving the circular plastic pipe 3 to the middle of the arc-shaped opening 1a. After the circular plastic pipe 3 is disassembled, the centering structure makes the cylinder 4 automatically return to the center, ensuring that when the circular plastic pipe 3 is placed on the next side, the circular plastic pipe 3 can axially slide towards both ends.

[0040] In one embodiment, elastic pads 5 are fixedly connected to the inner side of the arc-shaped opening 1a and at both ends of the base 1. The elastic pads 5 are also arc-shaped and are used to protect the two ends of the circular plastic pipe 3.

[0041] In one embodiment, the centering structure includes: at the bottom of the cylinder 4 and inside the through port 6, two groups of laterally distributed side ears 7 are fixedly arranged. On both sides of the side ears 7, a first connecting rod 8 and a second connecting rod 9 are respectively arranged. A shaft member 10 is fixedly connected between the first connecting rod 8 and the second connecting rod 9. The shaft member 10 is fixedly connected to the side ears 7. The first connecting rod 8 and the second connecting rod 9 are located on both sides of the connecting frame 11. And a second elastic member 13 is arranged between the first connecting rod 8 and the connecting frame 11, and a first elastic member 12 is arranged between the second connecting rod 9 and the connecting frame 11.

[0042] When the cylinder 4 axially slides, it will drive two groups of laterally distributed side ears 7, the first connecting rod 8 and the second connecting rod 9 to axially slide, thereby squeezing the first elastic member 12 or the second elastic member 13. When there is no external force, the resilience of the first elastic member 12 or the second elastic member 13 pushes the first connecting rod 8 and the second connecting rod 9, thereby returning the cylinder 4 to the middle of the long groove 2.

[0043] In one embodiment, two groups of long grooves 2 and cylinders 4 are provided. The two groups of long grooves 2 and cylinders 4 are radially stacked, so that the cylinder 4 can better support the circular plastic pipe 3.

[0044] In one embodiment, guiding flank pieces 17 are fixedly installed on the outer side of the base 1. Two groups of guiding flank pieces 17 are provided. The two groups of guiding flank pieces 17 are distributed on both sides of the base 1. The two groups of guiding flank pieces 17 facilitate guiding the circular plastic pipe 3 into the arc-shaped opening of the base 1.

[0045] In one embodiment, the base 1 is of a shell structure, making it easier to process and form.

[0046] In one embodiment, a rectangular opening is formed at the bottom of the base 1. The telescopic shaft of the bidirectional telescopic member 14 is located inside the rectangular opening. The rectangular opening is used to make way for the telescopic shaft of the bidirectional telescopic member 14.

[0047] In one embodiment, an inclined opening 16 is provided below the horizontal part of the inverted "L" shaped clamping member 15, which is used to guide the horizontal part of the inverted "L" shaped clamping member 15 to be inserted into the inside of the circular plastic pipe 3.

Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
