Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As fig. 1, fig. 2, fig. 3 shows, the utility model discloses a power lid convenient to installation, including lid 1, lid 1 is equipped with boundary beam 2, boundary beam 2 is equipped with a plurality of arcs 3, arcs 3 dispose cylinder 4, the cylinder 4 both ends are equipped with stifled dish 5, boundary beam 2 articulates there are a plurality of fixed parts 6, fixed parts 6 includes fixed plate 61, fixed plate 61 cross-section is the U type, fixed plate 61 is equipped with the breach of stepping down 62, fixed plate 61 both sides face is equipped with U type notch 63, U type notch 63 position corresponds arc 3, U type notch 63 oral area position is equipped with fillet 64, U type notch 63 both sides are equipped with the fixed mouthful 65 that the position corresponds each other, one of them fixed mouthful 65 runs through one side of U type notch 63, another fixed mouthful 65 sliding fit has fixed block 66, be connected with spring 67 between fixed block 66 and the fixed mouthful 65, fixed block 66 is equipped with inclined plane 68.

In this embodiment, when a power cover convenient for installation is used, the power housing 1 'is attached to the cover body 1, then the cylinder 4 is attached to the arc-shaped groove 3 on the boundary beam 2, then the fixing plate 61 is pressed down until the fixing block 66 contacts the cylinder 4, the round angle 64 plays a role of guiding in the pressing down process, and is pressed down with force continuously, the fixing block 66 can be accommodated into the fixing opening 65 under the effect of the inclined plane 68, but when the cylinder 4 completely enters the U-shaped notch 63, because the cylinder 4 is not in contact with the fixing block 66 any more, under the effect of the spring 67, the fixing block 66 can be popped up to enter another fixing opening 65, thereby fixing the cylinder 4 is realized, and under the effects of the fixing plate 61 and the blocking disc 5, the power housing 1' and the boundary beam 2 of the cover body 1 are attached to each other and cannot move, thereby realizing the fixed installation of the cover body 1, convenient and fast, and time and labor saving, when needing to dismantle, use the iron rod or the hard object that can pass through fixed mouthful 65 wantonly from the one end of the fixed mouthful 65 that link up, push up fixed block 66 in another fixed mouthful 65 completely, and fix fixed block 66 a period slightly from U type notch 63 side, then shift out fixed plate 61, can take out cylinder 4 from arc wall 3, then boundary beam 2 no longer receives the fixed power in both sides, just can be convenient take off lid 1, convenient and fast, and time and labor saving.

Preferably, after the position of cylinder 4 is fixed, stifled dish 5 hugs closely in fixed plate 61, and fixed plate 61 hugs closely in boundary beam 2, and fixed effect is guaranteed in such design, in fact, also can consider the clearance size of hugging closely according to particular case.

Preferably, the spring 67 is an industrial grade spring, which ensures the elasticity and the service life, and in fact, the selection of the spring 67 can be considered according to specific situations.

The equal clearance fit of preferred cylinder 4 and arc wall 3 and U type notch 63, such design guarantees that the removal of position can not take place after cylinder 4 is fixed, and in fact, also can consider clearance fit's size according to particular case.

Preferably, the inclined surface 68 is subjected to a heat treatment and a smooth grinding treatment, designed to ensure hardness and sliding effect in contact with the cylinder 4, and in fact, the hardness after the heat treatment may be taken into consideration as the case may be.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
