Pipe clamp limit structure

The invention belongs to the technical field of the pipe clamp limit structure, in particular to a phenomenon that the bolt can be easily separated from the casing after being assembled in the casing, and the bolt is packaged conveniently and quickly. The cover is disposed between the casing and the belt.

According to the conventional pipe clamp structure, please refer to FIG. 1 to FIG. 5 , which mainly comprises a casing 1 , a bolt 2 and a belt 3 , wherein the front end surface and the rear end surface of the casing 1 are a self-arc top surface 11 . The front and rear stop faces 12, 13 having the shaft holes 121, 131 are formed to be bent toward the inner side, and a concave shape is formed between the front and rear stop faces 12, 13 and the curved top surface 11. The accommodating area 14 is further formed with side flaps 15 and 16 respectively on the two sides of the housing 1, and one end of the side flaps 15 and 16 is formed with protruding pins 151 and 161 so that the pins 151 are formed. , 161 can be inserted into the positioning hole 30 at one end of the strap 3, and the bolt 2 that has been placed in the shaft holes 121, 131 of the housing 1 can be sandwiched between the housing 1 and the strap 3 It is rotatable; although the invention mentioned above can achieve the original purpose of the invention, it has been highly praised by the industry and the general operators, but in view of the industry's continuous innovation and breakthrough in research and development and technology, Applicants are working harder to study and improve, so that they are perfect and practical; plus, the inventors have updated the experimental tests and summarized them in countless times. The respondents' opinions on the actual operation of the fee and found that the following problems still need to be further improved:

1. Due to the assembly, the bolt is directly placed in the accommodating area of the housing (ie, the neck of the bolt and the end of the shaft are loosely fitted over the shaft hole of the housing), so that it is carried or rested Or it is quite easy to cause the bolt and the belt to fall off and fall off.

2. As mentioned above, when the bolt is turned by force, the tapered limit portion of the bolt will be drilled into the accommodating area of the casing due to the action of the thread, and the limit portion forming the bolt will stop before the shell The baffle is pushed upwards (ie, the casing is pushed upwards to force its pins out of the locating holes), so that it is impossible to tighten the object, and at the same time, it is impossible to increase the force it can withstand.

In view of the above, the present invention is directed to the lack of the above-mentioned prior art, and proposes a pipe clamp limit structure to effectively overcome the above problems, so as to benefit all consumers and manufacturers.

The main content of the pipe clamp limiting structure of the present invention is to provide a finite stop by the intersection of the curved top surface of the casing and the side panels, and the minimum distance between the inner sides of the two limiting portions is less than or It is equal to the maximum diameter of the threaded portion of the bolt, and is provided with a connecting portion on the rear end surface of the casing. As a preliminary assembly, the bolt and the casing are not separated from each other by easy collision, and the bolt can be removed from the casing. The resistance is used as a basis for increasing the tensile strength. At the same time, it can also make the shell have a continuous modular production function, in order to achieve the advantages of increasing production, reducing costs and improving competitiveness.

The present invention relates to a pipe clamp limiting structure, as shown in FIG. 6 to FIG. 11 , which comprises at least a casing 5 , a bolt 6 and a belt 7 , wherein the front end surface of the casing 5 is a self The curved top surface 50 is bent toward the inner side to form a cover surface 511 having a shaft hole 511 and the rear end surface 52 thereof is an uncovered open-cut open area, and the stop surface 51 to the rear end surface 52 forms a recessed accommodating area 53 for the bolt 6 to straddle the casing 5, and the curved top surface 50 of the casing 5 is formed with the side flaps 55, 56 slightly below the outer side. And at least one end of the side panels 55, 56 is formed with protruding legs 551, 561, and a limited stop 57, 58 is formed at the intersection between the two sides of the curved top surface 50 and the side panels 55, 56, respectively. Furthermore, it is preferable that the restricting portions 57, 58 have a straight surface or a slope or a curved surface which is disposed obliquely inward to increase the stress and deformation resistance of the casing 5, and the two adjacent restricting portions 57, 58 The minimum distance A between the inner sides is less than or equal to the maximum diameter B of the threaded portion 63 of the bolt 6, and is provided on the rear end surface 52 of the casing 5 with a connecting portion 521; a bolt 6, which The switch portion 60 is polygonal (including a convex shape or a concave shape) and has one end. It is connected to the limiting portion 61, and the other end of the limiting portion 61 is connected with the shaft portion 64, and a spiral thread portion 63 is distributed around the outer surface of the shaft portion 64, and the end portion and the limit portion of the thread portion 63 are arranged. A recessed neck portion 62 is formed between the portions 61; a band 7 is formed on the two sides of one end (ie, the head end), and a through hole 71 is formed in the middle of the second limiting groove 70. A positioning hole 72 is formed in the vicinity of the hole 71, so that the side flaps 55 and 56 of the housing 5 can be locked into the limiting slot 70 first, and then forced to bend until the pins on the side flaps 55 and 56 are bent. 551, 561 can be located or inserted into the positioning hole 72 of the band 7, and the band 7 is integrated with the casing 5; in addition, the other end (ie, the end) of the band 7 is formed in a continuous shape. The tooth portion 75 is such that the tooth portion 75 can be engaged with the threaded portion 63 of the bolt 6 that has been wrapped in the casing 5; when initially assembled, the accommodating portion 53 of the casing 5 is disposed upward ( Open The mouth end is upwards, and the minimum distance A between the inner sides of the second limiting portion 58 of the casing 5 is equal to or slightly smaller than the maximum diameter B of the threaded portion 63 of the bolt 6, so that when the bolt 6 is to be placed into the casing 5 When the accommodating area 53 is inside, the urging force must be applied first (that is, the casing 5 is deformed by its own elastic force and then returned to the original shape), and then the bolt 6 can be directly inserted into the accommodating area 53 to complete the bolt 6 It is combined with the casing 5 to be rotatably integrated, so that the technical problem that the conventional bolt 6 and the casing 5 are separated from each other by easy collision can be overcome.

At this time, after the limit grooves 70 on the two sides of the head end of the belt 7 are respectively aligned with the side flaps 55 and 56 of the casing 5, the pressure can be applied to force the two side flaps 55 and 56 toward each other. The direction is bent until the pins 551, 561 on the side panels 55, 56 can be located or inserted into the positioning holes 72 of the strap 7, and the band 7 is formed integrally with the housing 5, and the bolt 6 can be The cover is wrapped between the strap 7 and the housing 5 to be rotatable; at this time, if the strap 7 is tightly attached to the object (not shown), if the pulling force of the bolt 6 is continuously applied, the force is forced. When the driving screw portion 63 directly drives the tooth portion 75 of the strap 7 to move forward in a tighter state, the tapered limiting portion 61 of the bolt 6 is forced to be drilled into the stopping portion 51 of the housing 5. Simultaneously within the shaft hole 511, the front end of the housing 5 is forced to move upward, and when the housing 5 is to be moved upward, the restricting portions 57, 58 already located on the housing 5 are forced to abut first. The threaded portion 63 of the bolt 6 is used as a resistance for the bolt 6 to be drilled into the casing 5 or to be detached, and can be used as a basis for resisting tensile force. Further, the rear end surface 52 of the casing 5 of the present invention is provided with Portion 521, but as in the production of the housing 5, it can have a continuous modular production effect, to achieve increase production, reduce costs, and thus to improve their competitiveness.

Referring to FIG. 12, which is still another embodiment of the present invention, the main change is that the restricting portions 57, 58 of the original casing 5 are in a vertical plane or a sloped manner, and the limiting portions 57, 58 are changed. The curved surface is concave or convex, and the minimum distance A between the inner sides of the two adjacent restricting portions 57, 58 is less than or equal to the maximum diameter B of the threaded portion 63 of the bolt 6, and is at the rear end surface 52 of the casing 5. The connecting portion 521 is provided on the above; therefore, the technical means and principle of the structure of the casing 5, the bolt 6, the belt 7 and the like which are used in the present invention are described in detail above, and therefore will not be described herein.
