Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

This embodiment discloses an adjustable clamp, as shown in fig. 1, comprising a main band 1, the main band 1 being formed with an outer band 12, an inner band 13, a housing area 2 and a fastening portion 11 in a bent manner. The clamp is sleeved at the specified position on the pipe fitting through the sleeving area 2, and then the fastening part 11 is clamped tightly, so that the clamp is fixed at the specified position on the pipe fitting.

As shown in fig. 1, five position-limiting holes 121 are formed in the outer belt 12 on the side close to the belt end of the main belt 1 and are equidistantly distributed along the symmetry axis of the main belt 1, and a position-limiting piece 132 is fixedly arranged on the surface of the inner belt 13 facing the outer belt 12. The stopper 132 includes a left stopper 132a and a right stopper 132b having the same thickness and width, and the stopper 132 passes through the stopper hole 121 and abuts against the outer belt 12 to partially fix the outer belt 12 and the inner belt 13.

As shown in fig. 1 and 2, the outer tape 12 has a left outer groove 122a and a right outer groove 122b each having a square stripe shape and being symmetrical with respect to the axis of symmetry of the main tape 1, on a surface not facing the inner tape 13, and the inner tape 13 has a left inner groove 133a and a right inner groove 133b each having a square stripe shape and being symmetrical with respect to the axis of symmetry of the main tape 1, on a surface not facing the outer tape 12. The left outer groove 122a, the right outer groove 122b, the left inner groove 133a, the right inner groove 133b, the left stopper 132a, and the right stopper 132b have the same width. After the limiting piece 132 passes through the limiting hole 121, the left limiting piece 132a is bent leftwards, and is embedded into the left outer groove 122a and then embedded into the right outer groove 122 b; the right stopper 132b is bent to the right, and is inserted into the right outer groove 122b and then the right inner groove 133 b. Through the arrangement, the stress area of the limiting sheet 132 is increased, the structural strength of the clamp is enhanced, the maximum clamping degree of the fastening part 11 is effectively improved, and the fixing effect of the clamp on the pipe fitting is better; the limiting sheet 132 is completely embedded into the outer side belt 12 and the inner side belt 13, so that the hidden danger of damaging pipe fittings or human bodies is eliminated.

As shown in fig. 1 and 3, two reinforcing heads 131 with an i-shaped cross section are fixed on the surface of the inner belt 13 facing the outer belt 12 and are equidistantly distributed along the symmetry axis of the main belt 1. The distance between the two reinforcing heads 131 is equal to the distance between the reinforcing head 131 close to the limiting sheet 132 and the limiting sheet 132, and also equal to the distance between the limiting holes 121. After the position-limiting sheet 132 passes through the position-limiting holes 121 and is completely embedded in the outer belt 12 and the inner belt 13, the two reinforcing heads 131 also pass through two of the remaining position-limiting holes 121, respectively, and the two position-limiting holes 121 are adjacent to each other. Through these settings, the structural strength of clamp further strengthens, and the fixed effect of clamp on the pipe fitting further promotes.

As shown in fig. 1 and 4, a narrow plug 14 is disposed at an end of the main belt 1 away from the limiting hole 121, the plug 14 is symmetrical about a symmetry axis of the main belt 1, and two side surfaces of the plug 14 are parallel to the side surfaces of the main belt 1. The outer tape 12 is provided with a socket 15 into which the plug 14 is inserted. Two sides of the outer wall of the plug 14 are respectively and fixedly provided with a cutting 141, and the width of the cutting 141 is smaller than that of the main belt 1. Two sides of the inner wall of the socket 15 are respectively provided with a slot 151, and the width and depth of the slot 151 are respectively slightly larger than the width and thickness of the insert 141. As the plug 14 is inserted into the jack 15, the insert 141 is inserted into the slot 151. Through the arrangement, the outer side belt 12 and the inner side belt 13 can be attached together without deviation after being fixed, and the plug 14 does not have a part protruding out of the socket 15, so that the hidden danger of damaging a pipe fitting or a human body is further eliminated.

The following describes the effects of the present embodiment in conjunction with the use conditions:

the main belt 1 is bent and sleeved at a designated position on the pipe through the sleeving area 2. Two reinforcing heads 131 and a limiting piece 132 on the inner side belt 13 are inserted into three continuous limiting holes 121 on the outer side belt 12, the left limiting piece 132a is bent leftwards and is sequentially embedded into the left outer groove 122a on the outer side belt 12 and the left inner groove 133a on the inner side belt 13, and the right limiting piece 132b is bent rightwards and is sequentially embedded into the right outer groove 122b on the outer side belt 12 and the right inner groove 133b on the inner side belt 13. The plug 14 on the main belt 1 is inserted into the socket 15 on the outer belt 12, and the insert 141 on the plug 14 is inserted into the slot 151 on the socket 15 along with the plug 14. The fastening portion 11 is clamped using manual or pneumatic clamp pliers, and the clamp is fixed to the pipe. Because five limiting holes 121 are formed, the sleeving area 2 of the clamping hoop has three sizes which can be adjusted, so that the clamping hoop can be sleeved on pipe fittings with various external diameter specifications, and the purpose of adjustment is achieved.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
