Abstract
The utility model provides a novel self-locking clamp without using springs. The self-locking clamp comprises a cam and a clamping frame in structure, and the clamping frame comprises a clamp sheet and a fixed sheet which can fix the cam and cause the cam to rotate around a fixed shaft. A groove for enlarging friction is arranged on the cam at the side corresponding to the clamp sheet, and the gap between the cam and the clamp sheet is smaller and smaller when the cam rotates around the fixed shaft, clamping thin materials arranged in the gap firmly. The utility model has the advantages of simple structure, convenient manufacture.
Description
The utility model relates to articles for daily use, specifically, relates to daily used clip.
The clip of Chu Xianing in the market all utilizes the elastic force of spring to change into the folder power of clip, owing to use spring, preparation process is complicated, and difficulty relatively during assembling be difficult for enhancing productivity, and folder power is little, is generally about 2-3kg.
The purpose of this utility model is, the clip that provides a class not use spring makes simplifying the structure and helping assembling of clip, improves the folder power of clip simultaneously.
Above-mentioned purpose of the present utility model is to realize by following mode.
The utility model provides the self-locking clip, structurally comprises a cam and a clamping frame, the fixed plate that described clamping frame comprises an intermediate plate and makes described cam fix and rotate around fixing axle.
Clamping frame from the above mentioned down extends two fixed plates abreast from the top of described intermediate plate, two the terminal equal height of fixed plate places are provided with two apertures, described cam is arranged between above-mentioned two parallel fixed plates, respectively there is a pin cam both sides, insert respectively in two apertures on the said fixing sheet, also be provided with the handle of being convenient to make cam rotation on the cam.
Self-locking clip from the above mentioned, a relative side with cam of the intermediate plate on the clamping frame are provided with the tooth that increases frictional force, and the face relative with intermediate plate of cam is provided with the groove that increases friction.
The clamping frame of self-locking clip from the above mentioned is provided with one and hangs circle.
Advantage of the present utility model is as described below:
(1) do not use spring, simple in structure, easy to assembly.
(2) folder power is bigger, can hang the 5kg left and right weight plates.
(3) clamping is reliable, and using scope is wide, and all thin type soft materials all can use.
(4) easy to use, the outward appearance novelty.
Description of drawings:
Fig. 1 is the scheme of installation of self-locking clip of the present utility model.
Fig. 2 is the behaviour in service schematic representation of self-locking clip of the present utility model.
By the following examples the utility model is described in further detail, but protection domain of the present utility model is not limited.
Embodiment:
As shown in Figures 1 and 2, this self-locking clip is made up of clamping frame (2) and cam (1), is provided with one on the last top of fixed plate (4) and hangs circle (5).Described clamping frame (2) comprises intermediate plate (3) and two fixed plates (4) that stretched out abreast by an end of intermediate plate (3), and the terminal equal height of two fixed plates (4) offers aperture (6) respectively.Cam (1) is arranged between two fixed plates (4), and cam (1) both sides respectively are provided with a little round pin (7), and little round pin (7) inserts in the above-mentioned aperture of cam (1) (6), makes cam (1) fixing.Cam (1) is provided with handle (10) and stirs handle (10) gently with finger cam (1) is rotated according to fixing axle.
The side that cam (1) is relative with intermediate plate (3) is provided with the groove (9) that can increase frictional force, and is provided with tooth (8) on intermediate plate (3), also is in order to increase frictional force.
As shown in Figure 2, the soft object of thin type of desiring clamping is placed between cam (1) and the intermediate plate (3), stir handgrip (10) gently, cam (1) is rotated with finger, the face of cam (1) tooth of synchronous belt (9) nestles up intermediate plate (3), thereby object is tightly clamped.
Claims (4)
1, a kind of self-locking clip, it is characterized by, structurally comprise a cam and a clamping frame, the fixed plate that described clamping frame comprises an intermediate plate and makes described cam fix and rotate around fixing axle, described clamping frame extends two fixed plates abreast from an end of described intermediate plate, and two the terminal equal height of fixed plate places are provided with two apertures, and described cam is arranged between above-mentioned two parallel fixed plates, respectively there is a pin cam both sides, insert respectively in two apertures on the said fixing sheet.
2, by the described self-locking clip of claim 1, it is characterized by, also be provided with the handle of being convenient to make cam rotation on the cam.
