Description

Polygonal pipe clamp construction

The present invention relates to a pipe clamp structure; in particular, to a polygonal pipe clamp structure that can be quickly tightened on a polygonal object.

According to the conventional metal pipe clamp structure, the pipe clamp mainly includes: a shell, a belt for assembling the shell, and a bolt located between one end of the belt and the shell, wherein: The shell system consists of a shell part, a baffle part bent downward and in the shape of an inverted U on one side of the shell part, a concave chamber between the shell part and the baffle part, and a It is composed of legs that extend downward and are bent and covered for fixing to the belt body; and the bolt is composed of a tool (not shown in the figure, such as a screwdriver or a wrench, etc.) or a finger force wrench The movable pull part and the thread used to engage the tooth part of the belt body; the belt system is rolled into a long arc state, one end of which is used for fixing the shell assembly and the other end is provided with a through A long oblique hole in the shape of the bolt allows the thread of the bolt to engage in the oblique long hole and drive it to move to one side. In this way, when the end of the tooth portion of the belt body is inserted into the clamped When placed at the thread of the bolt between the housing and one end of the belt, the pull part can be turned with force to drive the thread to force the tooth part of the belt to move to one side until the belt can Tightly tighten around the round object.

Although the above creation can achieve its intended purpose, it will have the following shortcomings in operation and use:

Most of the hollow pipe fittings for gas or fluid in the market today are round pipe fittings, so that one end of the hollow pipe fitting is usually directly connected with a round hollow hose; in order to prevent gas in the round hollow pipe fitting Or if the liquid pressure is too high and the circular hollow hose is enlarged and jumped out, a circular pipe clamp slightly larger than the size of the circular hollow hose is usually selected and directly placed on the outside of the circular hollow hose. By locking it, you can ensure that the circular hollow pipe will not jump apart; however, for commercially available polygonal hollow pipe fittings, although you can choose a round one with a larger size than the polygonal hollow pipe fitting, When using pipe clamps together, since the circumferential size of the circular pipe clamp is much larger than the circumferential size of the polygonal hollow pipe fitting, it takes time to rotate during use so that the inside of the belt body can contact the polygonal hollow pipe fitting. At each corner, at this time, it is necessary to rotate harder to pull and deform the arc-shaped belt body and start to move closer to each side of the polygonal hollow pipe; at this time, it is necessary to rotate even harder to make the The deformed arc-shaped belt body is pulled and deformed again to get closer to each side of the polygonal hollow pipe. At this time, if the strength is insufficient, it can only present a rough locking state, but cannot be used reliably. The hose is tightly fixed to the polygonal hollow pipe. As a result, the locking state cannot be ensured after time-consuming and labor-intensive efforts, which is a major trouble for the user.

Therefore, how to develop a pipe clamp that can be quickly locked on a polygonal pipe fitting to improve the convenience of the user is currently a priority issue that needs to be solved by the industry.

The included angle formed between two adjacent clamping edges, and the tail end belt section is provided with equidistantly arranged teeth, so that the teeth at one end of the tail end belt section are inserted into the driving member and the head end between the belt segments, the rotation of the spiral thread of the driving member will force the tooth portion to move to one side until the object is tightened, and the head end belt segment and the tail end belt segment are located on the object At the same side of By changing the number of sides, the hoses of different materials can be more tightly compressed and tightened on the polygonal object without easily falling apart, thereby providing operational convenience of more quickly adjusting the tightening effect, and at the same time , can also expand the industrial fields of different products used, and help enhance the competitiveness of the industry as a progressive proposition.

The number of sides of 3 changes (i.e., from a pentagonal shape to a quadrilateral shape), until the polygonal shape (i.e., a quadrilateral) is obtained after adjusting the number of sides. The belt 3 will pressurize the hose 5 more tightly, so that the tightened The hose 5 can be more tightly compressed and tightened on the outside of the polygonal (i.e. quadrilateral) object 6, so that the head end belt section 30 and the tail end belt section 32 are located at the same side of the object 6 at the same time. (As shown in Figure 4); in this way, not only can it be quickly inserted into the outside of the polygonal object 6 with a similar number of sides, but also the polygonal shape can be quickly adjusted by slightly rotating the driving member 2 for a few turns. The number of sides of the belt body 3 changes (i.e., from a pentagonal shape to a quadrilateral shape), so that the hose 5 of different materials can be more tightly pressed and bundled in the polygonal shape (i.e., quadrilateral) of the object 6 without causing any problems. It can be easily detached and separated to provide operational convenience of adjusting the tightening effect more quickly. At the same time, it can also expand the industrial fields of different products used, which helps to enhance the competitiveness of the industry.
