Abstract

The utility model relates to a locking member for fixing something, comprising an opening mouth part and a sealing cover part, wherein, the opening mouth symmetrically supports two rolling wheels by a spring, and the two rolling wheels are arranged relatively; the side surface of the sealing cover part vertically extends a front part, and the shape of the longitudinal profile of the end part of the front part is a rhomb. When combined, the front part passes between the rollers, and the two rolling wheels abut on the neck part of the front part under the action of the spring force to finish fastening and combining.

Description

Locking member for fixing something

The utility model relates to a kind of buckle combining device, is meant a kind of buckle combining device that can repeat opening and capping switching effectively especially.

In the prior art, all make its secure bond for the combination of opening and capping, and must be provided with corresponding flight with screw.Therefore wanting the unlatching of combined part or close must the cost long time.In addition, if the repeated use screw may be lost or wear and tear, this just opens or closes and cause a lot of troubles implementing once more, or even the difficulty that is difficult to overcome.

Therefore, the purpose of this utility model provides a kind of buckle combining device, and this device can be implemented the open and close of the quick repetition of opening and capping.And the troublesome problem of the screw of also needn't worrying wearing and tearing and/or loss and so on.

The buckle combining device that the utility model proposes comprises opening portion and enclosure portion, it is characterized in that, have symmetrically arranged two U-shaped springs in the opening portion inboard, two set pins, two removable pins and two rollers, set pin is packed in an inside sidewalls of opening portion respectively, at the adjacent inside sidewalls of this a sidewall fixing supporting leg of one of U-shaped spring and another supporting leg of U-shaped spring is connected with removable pin respectively respectively, the bottom attaching mutually of set pin and U-shaped spring, roller are installed in rotation on separately the removable pin; The front portion that enclosure portion comprises cover plate and extends at the vertical cover plate of cover plate one side, the elevation profile of the head end that this is anterior is prismatic.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further, wherein:

Fig. 1 is the longitudinal sectional view of the opening portion of the buckle combining device that the utility model proposes;

Fig. 2 is the longitudinal sectional view of the enclosure portion of the buckle combining device that the utility model proposes;

Fig. 3 is the scheme drawing that the buckle combining device that the utility model proposes is bonding state.

The embodiment of the buckle combining device that the utility model proposes is used for the various apertures on the boiler of opening and the combination of capping thereof.As shown in Figure 1, opening portion 1 can be boiler body, inboard at the sidewall 9 of boiler body is fixed with two set pins 3 symmetrically, this set pin 3 respectively with the bottom attaching mutually of U-shaped spring 6, one supporting leg of one of two U-shaped springs 6 is separately fixed on the sidewall 10, and another supporting leg is connected with removable pin 4 respectively, and two rollers 5 are installed in rotation on respectively on separately the removable pin 4.

The vertical cover plate of the one side place plane earth of cover plate 7 extends a front portion 8, and the elevation profile of the termination of this front portion 8 is prismatic.(see figure 2).

When buckle in conjunction with the time (seeing also Fig. 3), cross between two symmetrically arranged rollers 5 the prismatic termination of the front portion 8 of capping 2, thereby make two rollers 5 owing to the elastic force of U-shaped spring 6 clamps neck place to anterior 8, capping 7 just is fixed on the opening portion 1 like this, reaches sealing and covers state.When need separate capping 7, only need pull at from capping 7, the inclined side of the prismatic termination of its front portion 8 forces two rollers 5 separately, and 7 of cappings can easily be left opening portion 1 and make it opening and open wide.

The utility model has the advantages that the switching opening portion is very quick, only needed for one or two second, if connect capping with screw, then opening and closing needs two or three minutes. And the misgivings and the trouble that do not have the screw wearing and tearing or lose and so on.

Claims
