CN2846844Y - Expansion clamp - Google Patents

Abstract

The utility model discloses an expansion-shaped clamp, which is composed of a clamp head at the top end, a clamp body and a clamp disk which are at the middle part, and a clamp bottom part at the lower end, wherein the clamp body is divided into two to three big blocks along the circumferential direction, and the whole clamp body forms a tapered shape so that the clamp body has the advantages of good intensity, convenient clamping, difficult pull and difficult fracture in the process of clamping; simultaneously, the bottom side of the clamp body is inwards provided with a step to form a clamping side, when the whole clamp tightly clamps objects, the clamp has tension on the objects, namely the clamp can position and has a fastening function; the clamp body is provided with a fine cylindrical clamping head, and the clamping head is used for positioning and guidance; the clamp bottom part uses a screw column form, so that the assembly, the disassembly and the repeated use of the clamp are convenient. The expansion-shaped clamp has the advantages of simple and obvious structure, easy fabrication and the easy assurance of production accuracy.

Description

A kind of type buckle that rises

Technical field

The utility model belongs to the clamping technology, the type buckle structure of using always on a kind of automobile of specific design that rises.

Background technique

The structure majority of the type buckle that rises commonly used is that mostly there is following shortcoming and defect in they as Fig. 1 or structure shown in Figure 2 on the domestic automobile at present: the one, and buckle dop part 11 complex structures; The 2nd, buckling body part 12 piecemeal part areas are less, and installation process ruptures easily; Three buckle bulk strengths a little less than, insecure to the clamping of corresponding clamping thing, can only play positioning action.

Summary of the invention

The purpose of this utility model is at the prior art above shortcomings, and a kind of type buckle that rises of new structure is provided, and can satisfy the effect of buckle as locating column, can play certain connection, fastening effect again.

The technical solution adopted in the utility model is as follows:

Originally the type that rises buckle is divided into several parts in buckle bottom of the dop on top, middle buckling body and chuck, lower end and forms, and buckling body along the circumferential direction is divided into the 2-3 bulk, and whole buckling body is tapered, whole like this buckle intensity is good, be convenient to stick into, be difficult to extract, clamping process buckle is easy-rupturing not.Receive a step simultaneously in the base of buckling body and form the clamping limit, unique clamping limit makes whole being buckled in when tightening object has tension force to object, and promptly buckle not only can be located and can also be played the role of fastening.

In the clamping process, need the condition of a guiding and location to be convenient to make the fastening can directive clamping, so designed the dop of thin cylinder on the buckling body, its role is to location and guiding.In addition, the screw column form is adopted in the buckle bottom, so that the installation and removal of buckle and recycling.

Therefore, the type that originally rises buckle structure is simple, and is easy to manufacture, and the production precision is easy to guarantee.

Description of drawings

Fig. 1 is a kind of structural drawing of the common type buckle that rises;

Fig. 2 is the structural drawing of the common type buckle that rises of another kind;

Fig. 3 is the type buckle structure figure that rises that the utility model provides.

Among the figure: 11-dop part 12-buckling body part

24-chuck 25-buckle bottom, 21-dop 22-buckling body 23-clamping limit

Embodiment

The concrete structure of whole buckle is as shown in Figure 3: the type that originally rises buckle is made up of buckle bottom more than 25 parts of the dop 21 on top, middle buckling body 22 and chuck 24, lower end, and dop 21 is thin round column structure.Buckling body 22 along the circumferential direction is divided into two major parts A and B, and whole buckling body is tapered, receives a step in the base of buckling body and forms clamping limit 23, and buckle bottom 25 is the screw column form.

Claims (3)

1, a kind of type buckle that rises, several parts in buckle bottom that are divided into the dop on top, middle buckling body and chuck, lower end are formed, it is characterized in that: buckling body along the circumferential direction is divided into the 2-3 bulk, and whole buckling body is tapered, and receives a step formation clamping limit in the base of buckling body.

2, the type buckle that rises according to claim 1, it is characterized in that: the dop on the buckle top is thin round column structure.

3, the type buckle that rises according to claim 1 is characterized in that: the buckle bottom is threaded stud structure.
