Its structure is generally a ring-shaped metal band, which can be fastened through screws or other adjustment mechanisms to ensure the stability of the fixed object. Clamps are widely used in fields such as automobiles, construction, and pipeline engineering to provide stable connections and supports. In an existing clamp, both ends are locked and connected by a locking bolt, and the connecting part is bow-shaped. When the clamp is used to tighten the butt-jointed pipe fittings, during the locking process, the side parts of the clamp are less affected by the bolt tension, and the force on the clamp in the width direction is uneven. The clamp is prone to deformation during use, and the deformation will affect the stability of the clamp, and further affect its fixing effect on the pipe fittings. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-deformation clamp, which can effectively improve the stability of the clamp and prevent the problem of poor fixing effect caused by the deformation of the hoop band.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An anti-deformation clamp in the utility model includes a hoop band, a first plug, a second plug, and a locking bolt; the hoop band is a notched ring formed by bending a stainless steel strip, and both ends of the hoop band are respectively provided with a connecting part A and a connecting part B; both the connecting part A and the connecting part B have inner cavities that penetrate in the width direction of the hoop band; the first plug is inserted into the connecting part A, the shape of the first plug matches the shape of the inner cavity of the connecting part A, and the length of the first plug is equal to the width of the connecting part A; the second plug is inserted into the connecting part B, the shape of the second plug matches the shape of the inner cavity of the connecting part B, and the length of the second plug is equal to the width of the connecting part B; the locking bolt penetrates from one side of the connecting part A and is screwed with a locking nut after sequentially passing through the connecting part A, the first plug, the second plug, and the connecting part B.

[0027] Please refer to Figures 1 to 5 , an anti-deformation clamp is provided in the embodiments of the present utility model, which includes a hoop band 1, a first plug 6, a second plug 7, and a locking bolt 5; the hoop band 1 is a notched ring formed by bending a stainless steel strip, and both ends of the hoop band 1 are respectively provided with a connecting portion A11 and a connecting portion B12; both the connecting portion A11 and the connecting portion B12 have inner cavities penetrating along the width direction of the hoop band 1; the first plug 6 is inserted into the connecting portion A11, the shape of the first plug 6 matches the shape of the inner cavity of the connecting portion A11, and the length of the first plug 6 is equal to the width of the connecting portion A11; the second plug 7 is inserted into the connecting portion B12, the shape of the second plug 7 matches the shape of the inner cavity of the connecting portion B12, and the length of the second plug 7 is equal to the width of the connecting portion B; the locking bolt 5 penetrates from one side of the connecting portion A11, and after sequentially passing through the connecting portion A11, the first plug 6, the second plug 7, and the connecting portion B12, a locking nut 4 is screwed. By providing the first plug 6 arranged along the width direction in the connecting portion A11 and the second plug 7 arranged along the width direction in the connecting portion B12, the connecting portion A11 and the connecting portion B12 can be supported, enhancing their anti-deformation ability. Moreover, when the two ends of the hoop band 1 are tightened by the locking cooperation of the locking nut 4 and the locking bolt 5, the presence of the first plug 6 and the second plug 7 can make the tension received in the width direction of the hoop band relatively uniform, thereby effectively avoiding the problem of local deformation of the hoop band, ensuring the stability and fixing effect of the clamp lock, and having good practicability.

[0028] In this embodiment, the connecting part A11 and the connecting part B12 are formed by bending the end of the strap 1 in the opposite direction. The cross-sectional shapes of the first plug 6 and the second plug 7 are semi-circular, and the arc surfaces of the first plug 6 and the second plug 7 face each other. In this way, the first plug 6 and the second plug 7 can be respectively inserted into the connecting part A11 and the connecting part B12 and effectively positioned to prevent the first plug 6 and the second plug 7 from rotating.

[0029] Furthermore, as Figure 2 shown, the locking bolt 5 includes a bolt head 51, a stud portion 53, and a square column portion 52. The square column portion 52 connects the bolt head 51 and the stud portion 53 as a whole. A first square hole 13 is provided on the side of the connecting part A11, and a second square hole 61 is provided on the side of the first plug 6. After the locking bolt 5 is locked, the square column portion 52 is embedded in the first square hole 13 and the second square hole 61, and the stud portion 53 passes through a first round hole 14 provided on the connecting part B12 and a second round hole 71 provided on the second plug 7. In this technical solution, the circumferential limit of the locking bolt 5 is realized by the cooperation of the square column portion 52 with the first square hole 13 and the second square hole 61, so as to ensure that the locking bolt 5 does not rotate with the locking nut 4 during the locking operation, making the locking operation more convenient.

[0030] In some embodiments, as Figure 4 shown, a connecting member 8 is fixedly installed on the end face of the first plug 6. The connecting member 8 can be fixedly connected to the first plug 6 by screws or welding. An installation seat 9 is installed at one end of the connecting member 8 away from the first plug 6. Combining Figure 3 and Figure 4 , after fixing the connecting member 8 and the installation seat 9, the clamp can be installed and positioned. Such an installation and positioning structure is not directly designed on the strap 1, and there is no need to redesign the strap 1. It can be modified and upgraded based on the existing strap 1. In addition, since it is not directly designed on the strap 1, deformation of the strap 1 during processing can be avoided.

[0031] Furthermore, the connecting member 8 has a turning portion with an arc or a fold angle, and the angle between the clamp and the installation seat 9 is changed through the turning portion to adapt to different installation positions, with better flexibility.

[0032] In some embodiments, a lining ring 2 is provided on the inner side of the strap 1, and a rubber pad 3 is provided on the inner side of the lining ring 2. After the pipeline is butted and the clamp is locked, the rubber pad 3 can tightly fit the joint between the pipelines to effectively seal.

[0033] In some embodiments, as Figure 3 and Figure 5As shown, in order to prevent the problem that the locking bolt 5 is prone to falling off during the installation process of the locking bolt 5, a V-shaped spring piece 10 is sleeved on the stud portion 53 at the position between the connecting portion A6 and the connecting portion B7. The V-shaped spring piece 10 is preferably formed by bending a stainless steel sheet. The included angle of the V-shaped spring piece 10 is less than 90 degrees. The length direction of the waist-shaped perforation 101 is the same as the height direction of the V-shaped spring piece 10. Waist-shaped perforations 101 for the stud portion 53 to pass through are provided on two opposite side walls of the V-shaped spring piece 10. In the normal state, the edge of the waist-shaped perforation 101 is stuck on the thread of the stud portion 10, thereby playing a limiting role on the locking bolt 5 to prevent it from falling off. When locking the lock nut, by squeezing and closing the V-shaped spring piece 10, the V-shaped spring piece 10 can slide on the stud portion 53, so that the V-shaped spring piece 10 does not hinder the locking of the lock nut 4.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
