Abstract

This application relates to a high-strength clamp, specifically to the technical field of clamps. The clamp includes a clamp body comprising a clamping part, a fixing part, and a connecting part. The connecting part is provided with a first locking member and a second locking member. The fixing part has a first locking hole for inserting the first locking member and a second locking hole for inserting the second locking member. The fixing part has an abutment block on the side of the first locking hole away from the clamping part, and the end of the first locking member away from the clamping part has a force-applying part. This application, through the cooperation between the force-applying part on the first locking member and the abutment block, allows the force-applying part on the first locking member to abut and press against the outer wall of the abutment block when the clamping part is clamped using pliers. This reduces the stress at the contact point between the first locking member and the inner edge of the first locking hole when the clamp is tightened, and also reduces the possibility of tearing at the four corners of the inner edge of the first locking hole, thereby improving the tear resistance of the clamp.

Description

Technical Field

[0001] This application relates to the technical field of clamps, and in particular to a high-strength clamp. Background Technology

[0002] A clamp is a device used to fix, connect, or restrain pipes, fittings, and other components, and is usually made of metal. Existing clamp structures include various types such as single-ear clamps, double-ear clamps, T-clamps, U-clamps, and bent clamps, each suitable for different application scenarios.

[0003] In related technologies, refer to Figure 1 A stepless clamp includes a clamping lug 4, a fixing plate 5, and a connecting plate 6. The two sides of the clamping lug 4 are connected to the fixing plate 5 and the connecting plate 6 respectively, and the three are integrally formed. The connecting plate 6 is provided with two locking blocks 61 and one locking block 62. The fixing plate 5 is provided with a first fixing hole 51 for inserting the two locking blocks 61 and a second fixing hole 52 for inserting the locking block 62. When using the clamp, the two locking blocks 61 are inserted into the two first fixing holes 51 and the locking block 62 is inserted into the second fixing hole 52. Then, the clamping lug 4 is clamped with pliers to tighten the clamp. The locking blocks 61 abut against the inner edge of the first fixing hole 51 and the locking block 62 abuts against the inner edge of the second fixing hole 52.

[0004] However, when tightening the clamp using pliers, because the first and second fixing holes are stamped square holes with four sharp corners along their inner edges, stress tends to concentrate at these sharp corners when the clamp is tightened. Over-tightening the clamp may lead to issues such as… Figure 1 The first fixing hole is subjected to tensile deformation, and the fixing piece of the clamp is directly broken due to tearing at the corner of the first fixing hole. Summary of the Invention

[0005] The purpose of this application is to provide a high-strength clamp to solve the problem in the above-mentioned related technologies that when the clamp is over-tightened, the stress is concentrated at the sharp corner of the inner edge of the square hole, which may cause the clamp to deform or tear.

[0006] The high-strength clamp provided in this application adopts the following technical solution:

[0007] A high-strength clamp includes a clamp body, which comprises a clamping part, a fixing part, and a connecting part. The clamping part is fixedly connected to the fixing part and the connecting part on both sides, respectively. The connecting part has a first locking member near the clamping part and a second locking member away from the clamping part. The fixing part has a first locking hole for inserting the first locking member and a second locking hole for inserting the second locking member. The fixing part has an abutment block on the side of the first locking hole away from the clamping part, and a force-applying part is provided at the end of the first locking member away from the clamping part. When the clamp is in a tightened state, the force-applying part and the abutment block press against each other.

[0008] By adopting the above technical solution, when the clamp is used to fix the part to be fixed, the clamp is sleeved on the outer circumference of the part to be fixed, the first locking member is inserted into the first locking hole, and the second locking member is inserted into the second locking hole. With the setting of the abutment block, when the clamping part is clamped with pliers, the force-applying part on the first locking member abuts and presses against the outer wall of the abutment block, thereby reducing the stress at the abutment point between the first locking member and the inner edge of the first locking hole when the clamp is tightened, and also reducing the possibility of tearing at the four corners of the inner edge of the first locking hole, thereby improving the tear resistance of the clamp.

[0009] Optionally, there are two abutment blocks, which are located at the two corners of the first locking hole away from the clamping part. There are also two force-applying parts, which are located at the two shoulders of the first locking member. The positions of the two force-applying parts correspond to the positions of the two abutment blocks.

[0010] By adopting the above technical solution, when the clamp is in the tightened state, through the cooperation of the two force-applying parts and the corresponding two abutting blocks, the two force-applying parts abut against and press against the outer wall of the corresponding abutting block, thereby better reducing the stress concentration at the inner edge of the first locking hole when the clamp is tightened, and thus better improving the performance and service life of the clamp.

[0011] Optionally, the abutment block extends into a strip shape towards the clamping part, and the two abutment blocks are located on both sides of the first locking hole.

[0012] By adopting the above technical solution, since the abutment block extends into a strip shape towards the clamping part, and the two abutment blocks are located on both sides of the first locking hole, the structural strength of the first locking hole is improved, and the possibility of tensile deformation or even tearing of the first locking hole when the clamp is tightened is reduced.

[0013] Optionally, the fixing part is provided with a first reinforcing block in the shape of a convex strip, and the first reinforcing block is arranged in an arc around the side of the first locking hole near the clamping part; the two ends of the first reinforcing block are respectively connected to two abutting blocks.

[0014] By adopting the above technical solution, when the clamp is tightened, the force-applying part abuts and presses against the outer wall of the abutting block. Through the cooperation of the first reinforcing block and the abutting block, the first reinforcing block and the abutting block surround the first locking hole, thereby further improving the structural strength of the first locking hole. At the same time, it reduces the magnitude of the stress concentrated on the inner edge of the first locking hole when the clamp is tightened, and reduces the possibility of the first locking hole undergoing tensile deformation or even breakage when the clamp is tightened.

[0015] Optionally, the first locking member is provided with a limiting part located between the two force-applying parts.

[0016] By adopting the above technical solution, when the clamp is tightened, the limiting part abuts against the outer edge of the first locking hole through the setting of the limiting part, thereby reducing the possibility that the first locking part will come out of the first locking hole after the clamp is tightened.

[0017] Optionally, one abutment block is provided. The abutment block is arc-shaped and extends from one corner of the first locking hole away from the clamping part to another corner away from the clamping part. Two force-applying parts are provided. The two force-applying parts are respectively provided on the two shoulders of the first locking member. The two force-applying parts correspond to the two corners of the first locking hole away from the clamping part.

[0018] By adopting the above technical solution, when the clamp is tightened, the two force-applying parts abut and press against the corresponding positions on the outer wall of the abutment block, thereby reducing the stress concentration at the two corners of the first locking hole away from the clamping part when the clamp is tightened, and better improving the structural strength of the inner edge of the first locking hole away from the clamping part, thus improving the tear resistance of the clamp.

[0019] Optionally, the fixing part is provided with a second reinforcing block in the shape of a convex strip, and the second reinforcing block is arranged in an arc around the side of the first locking hole near the clamping part; the two ends of the second reinforcing block are respectively connected to the two ends of the abutment block.

[0020] By adopting the above technical solution, the second reinforcing block and the abutting block surround the first locking hole as a whole. When the clamp is tightened, the force-applying part on the first locking member abuts against the outer wall of the abutting block. Through the cooperation of the second reinforcing block and the abutting block, the structural strength of the first locking hole is further improved, the stress concentration at the inner edge of the first locking hole is reduced when the clamp is tightened, and the possibility of tensile deformation or even breakage of the first locking hole when the clamp is tightened is also reduced.

[0021] Optionally, the abutting block is formed by stamping the fixing part using a stamping device, and there is a gap between the inner edge of the first locking hole and the abutting block.

[0022] By adopting the above technical solution, during the stamping process of the abutment block, there is a gap between the inner edge of the first locking hole and the abutment block, which facilitates the stamping process of the abutment block and improves the processing efficiency of the abutment block.

[0023] Optionally, the inner edge of the first locking hole away from the clamping part is flush with the outer wall of the abutment block.

[0024] By adopting the above technical solution, when the clamp is tightened, since the inner edge of the first locking hole away from the clamping part is flush with the outer wall of the abutment block, it is convenient for the force-applying part to abut and press against the outer wall of the abutment block, making the clamp more secure when tightened.

[0025] Optionally, the outer edge of the second locking hole is provided with an abutment block that has the same structure as the first locking hole, and the second locking member is provided with a force-applying part and a limiting part that have the same structure as the first locking member.

[0026] By adopting the above technical solution, when the clamp is tightened, the second locking member is also inserted into the corresponding second locking hole, and the force-applying part on the second locking member abuts and presses against the outer wall of the abutting block, and the limiting part on the second locking member abuts against the outer edge of the second locking hole, thereby reducing the possibility of tensile deformation or even tearing of the second locking hole when the clamp is tightened, and further improving the tear resistance of the clamp.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By cooperating with the force-applying part on the first locking member and the abutment block, when the clamping part is clamped with pliers, the force-applying part on the first locking member abuts and presses against the outer wall of the abutment block, thereby reducing the stress at the abutment point between the first locking member and the inner edge of the first locking hole when the clamp is tightened, and also reducing the possibility of tearing at the four corners of the inner edge of the first locking hole, thereby improving the tear resistance of the clamp.

[0029] 2. By cooperating with the abutment block and the first reinforcing block, when the clamp is tightened, the force-applying part abuts against the outer wall of the abutment block, and the first reinforcing block and the abutment block better surround the first locking hole, thereby further improving the structural strength of the first locking hole, reducing the stress concentration at the inner edge of the first locking hole when the clamp is tightened, and also reducing the possibility of the first locking hole undergoing tensile deformation or even breakage when the clamp is tightened.

[0030] 3. Since the outer edge of the second locking hole is provided with an abutment block with the same structure as the first locking hole, and the second locking member is provided with a force-applying part and a limiting part with the same structure as the first locking member; when the clamp is tightened, the second locking member is also inserted into the corresponding second locking hole, and the force-applying part on the second locking member abuts and presses against the outer wall of the abutment block, and the limiting part on the second locking member abuts against the outer edge of the second locking hole, thereby reducing the possibility of tensile deformation or even tearing of the second locking hole when the clamp is tightened, and further improving the tear resistance of the clamp.

Detailed Implementation

[0041] The present application will be further described in detail below with reference to all the accompanying drawings.

[0042] Example 1:

[0043] Reference Figure 2 A high-strength clamp includes a clamp body, which includes a clamping part 1, a fixing part 2, and a connecting part 3. The two sides of the clamping part 1 are fixedly connected to the fixing part 2 and the connecting part 3, respectively. The clamping part 1, the fixing part 2, and the connecting part 3 are integrally formed.

[0044] Reference Figure 2 and Figure 3 The connecting part 3 is provided with a first locking member 31 near the clamping part 1 and a second locking member 32 away from the clamping part 1. The first locking member 31 and the second locking member 32 are both stamped by a stamping equipment, and the fixing part 2 is provided with a first locking hole 21 for the first locking member 31 to be inserted and a second locking hole 22 for the second locking member 32 to be inserted.

[0045] Reference Figure 4 The first locking element 31 is away from the clamping part 1 (see Figure 2 One end of the first locking member 31 is provided with two force-applying parts 311 and a limiting part 312 located between the two force-applying parts 311. The two force-applying parts 311 are respectively provided on the two shoulders of the first locking member 31. The position of the force-applying parts 311 on the first locking member 31 is similar to the two shoulders of a person.

[0046] Reference Figure 3 and Figure 4 On the fixing part 2, the first locking hole 21 is far from the clamping part 1 (see...) Figure 2 Two abutment blocks 23 are provided on one side of the first locking hole 21, and the two abutment blocks 23 are respectively located away from the clamping part 1 (see Figure 2 At the two corners of the clamp, the two force-applying parts 311 correspond to the two abutting blocks 23. When the clamp is in the tightened state, the force-applying parts 311 on the first locking member 31 abut against the outer wall of the abutting block 23 and press against each other. The abutting block 23 is formed by stamping the fixing part 2 with a stamping machine. The first locking hole 21 is also formed by stamping with a stamping machine. There is a gap between the inner edge of the first locking hole 21 and the abutting block 23. Since there is a gap between the inner edge of the first locking hole 21 and the abutting block 23, the processing order of the abutting block 23 and the first locking hole 21 can be either stamped, which is convenient for stamping the abutting block 23.

[0047] Reference Figure 4The connecting part 3 is provided with a positioning strip 33, and the fixing part 2 is provided with a positioning hole 24 for the positioning strip 33 to be inserted. When the clamp is tightened, the positioning strip 33 on the connecting part 3 is inserted into the positioning hole 24 on the fixing part 2 and then bent and fixed by pliers, thereby improving the stability of the clamp during use. The outer edge of the second locking hole 22 is provided with an abutment block 23 with the same structure as the first locking hole 21, and the second locking member 32 is provided with a force-applying part 311 and a limiting part 312 with the same structure as the first locking member 31, thereby further improving the tear resistance of the clamp.

[0048] The implementation principle of this application embodiment is as follows:

[0049] When the clamp is used to fix the part to be fixed, the clamp is placed on the outer circumference of the part to be fixed, the first locking member 31 is inserted into the first locking hole 21, and the second locking member 32 is inserted into the second locking hole 22. Then, after clamping the clamping part 1 with pliers, the force-applying part 311 on the first locking member 31 and the second locking member 32 abuts against the outer wall of the abutting block 23, thereby reducing the stress at the abutment point between the first locking member 31 and the inner edge of the first locking hole 21 when the clamp is tightened. At the same time, it also reduces the possibility of tearing at the four corners of the inner edges of the first locking hole 21 and the second locking hole 22, thereby improving the tear resistance of the clamp.

[0050] Example 2:

[0051] Reference Figure 5 The difference between this embodiment and Embodiment 1 is that the first locking hole 21 is located away from the clamping part 1 (see...). Figure 2 The inner edge of the locking hole 21 is flush with the outer wall of the abutment block 23, that is, the first locking hole 21 is far away from the clamping part 1 (see Figure 2 There is no gap between the inner edge of the locking member 21 and the abutment block 23; when the clamp is tightened, the force-applying part 311 on the first locking member 31 directly abuts and squeezes the outer wall of the abutment block 23, which can better reduce the stress on the inner edge of the first locking hole 21 when the clamp is tightened and improve the tear resistance of the clamp.

[0052] Example 3:

[0053] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that the abutment block 23 extends into a strip shape in the direction close to the clamping part 1, and the two abutment blocks 23 are respectively located on both sides of the first locking hole 21, so as to improve the structural strength of the first locking hole 21 and reduce the possibility of deformation or breakage of the first locking hole 21 when the clamp is tightened.

[0054] Example 4:

[0055] Reference Figure 7The difference between this embodiment and Embodiment 3 is that the fixing part 2 is provided with a first reinforcing block 25 in the shape of a protruding strip. The first reinforcing block 25 is stamped by a stamping equipment, and the first reinforcing block 25 is arranged in an arc around the side of the first locking hole 21 near the clamping part 1. The two ends of the first reinforcing block 25 are respectively connected to two abutting blocks 23. This is to further improve the structural strength of the first locking hole 21 and further reduce the possibility of deformation or tearing of the first locking hole 21 when the clamp is tightened.

[0056] Example 5:

[0057] Reference Figure 8 The difference between this embodiment and Embodiment 3 is that the number of abutment blocks 23 is one, and the abutment block 23 is generally arc-shaped. The abutment block 23 extends from one corner of the first locking hole 21 away from the clamping part 1 to the corner away from the clamping part 1 (see...). Figure 7 At the other corner, the two force-applying parts 311 located on the shoulders of the first locking member 31 are away from the clamping part 1 and the first locking hole 21 (see Figure 7 The two corner positions of the first locking member 31 correspond to each other; when the clamp is tightened, the two force-applying parts 311 on the shoulders of the first locking member 31 abut against and press against the outer wall of the corresponding position on the abutment block 23. Since there is only one abutment block 23, it is convenient for workers to process and stamp the abutment block 23 through stamping equipment.

[0058] Example 6:

[0059] Reference Figure 9 The difference between this embodiment and Embodiment 5 is that a second reinforcing block 26 in the form of a protruding strip is provided on the fixing part 2. The second reinforcing block 26 is stamped out by a stamping device, and the second reinforcing block 26 is arranged in an arc around the side of the first locking hole 21 near the clamping part 1. The two ends of the second reinforcing block 26 are respectively connected to the two ends of the abutment block 23. The second reinforcing block 26 and the abutment block 23 together surround the outer edge of the first locking hole 21, thereby further improving the structural strength of the first locking hole 21 and reducing the possibility of tensile deformation or tearing of the first locking hole 21 when the clamp is tightened.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
