Abstract

The utility model provides a reverse rotation locking device aiming at the defects of complicated structure and high cost of the existing reverse rotation locking device. The reverse rotation locking device comprises an outer wheel and an inner wheel, wherein the outer surface of the inner wheel is provided with a groove which is internally provided with a spring; the top end of the spring is provided with a sliding block I which is provided with an inclined plane at one side; the outer wheel is sheathed and connected with the inner wheel; the inner surface of the outer wheel is fixedly provided with a sliding block II; the structure of the sliding block II corresponds to that of the sliding block I; namely, the sliding block II is provided with an inclined plane corresponding to the inclined plane on the sliding block I. The reverse rotation locking device can realize relative rotation along one side direction by the inclined planes between the sliding block I and the sliding block II and can not rotate along the opposite direction since a plane is arranged behind the sliding blocks, thereby achieving the aim of preventing reverse rotation. The reverse rotation locking device is simple in structure so as to achieve the aim of preventing reverse rotation due to the simple structure, is convenient to use and is good in reverse rotation prevention effect, thereby being beneficial to popularization and application.

Description

Anti-reverse mechanism

Technical field:

The utility model relates to a kind of device of reversing of can preventing.

Background technique:

Now often some cylindrical device only needs rotation facing one direction, and the complex structure of existing anti-reverse mechanism own prevents the effect of reversing though can play, but because complex structure is with high costs, so be unfavorable for actual use.

The model utility content:

Have complex structure drawback with high costs at present anti-reverse mechanism, the utility model provides a kind of anti-reverse mechanism, can address the above problem preferably.

Described purpose is achieved by the following scheme:

A kind of anti-reverse mechanism comprises foreign steamer and interior wheel, and the outer surface of described interior wheel is provided with groove, lays spring in the described groove, and the slide block that a side has the plane of inclination is installed on described spring top; Described foreign steamer and interior wheel socket-connect, and the internal surface of described foreign steamer fixedly installs slide block No. two, and described No. two slide blocks are and the corresponding structure of slide block promptly to be provided with and the corresponding inclined-plane of slide block on No. two slide blocks.

The utility model can be realized the relative rotation of a side direction by slide block and the inclined-plane between No. two slide blocks, but since the slide block back be the plane therefore can not the opposite direction rotation, so it has realized anti-reverse purpose.The utility model is simple in structure, has promptly reached anti-reverse purpose by simple structure, and it is easy to use, and is anti-reverse effective, therefore is beneficial to and applies.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Wherein,

interior wheel

1,2, No. two slide blocks 3 of foreign steamer, 4, numbers slide blocks 5 of spring, groove 6.

Embodiment:

Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.

Present embodiment provides a kind of anti-reverse mechanism, and with reference to Fig. 1, it comprises foreign steamer 2 and interior wheel 1, and the outer surface of described interior wheel 1 is provided with groove 6, lays spring 4 in the described groove 6, and the slide block 5 that a side has the plane of inclination is installed on described spring 4 tops; Described foreign steamer 2 socket-connects with interior wheel 1, and the internal surface of described foreign steamer 2 fixedly installs slide block 3 No. two, and described No. two slide blocks 3 are and slide block 5 corresponding structures promptly to be provided with and slide block 5 corresponding inclined-planes on No. two slide blocks 3.

Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; the short of spirit that exceeds this patent all is considered as the replacement that is equal to this patent, all within the protection domain of this patent.
