Abstract

The utility model provides a cover capable of being opened and closed automatically by utilizing gravity, which relates to the novel application of the principle that the direction of earth gravity is always downward uprightly and the fundamental principle of a lever. The utility model solves the troublesome problems that a common cover only can be manually opened and closed and is easy to lose. The cover comprises a cover body, a hard lever, an acting component, a pipe body and a threaded cover, wherein the hard lever is connected with the cover body, the acting component is formed by connecting the other end of the hard lever and a weight block through a rotating shaft, the pipe body is fixed with the rotating shaft and is provided with a gap, and the threaded cover is fixed below the pipe body with the gap. The utility model has simple structure and low manufacturing cost, only needs to install the device on a traditional bottle, can be opened and closed automatically by the gravity without large change, is convenient for people to automatically open and close the cover, has the function of dust prevention, also solves the problem of easy loss of the cover and has obvious economic benefit and very extensive market prospect.

Description

The automatic folding cover of dust of gravity

Affiliated technical field

The direction that the utility model relates to gravity always reaches the device that the groundwork of leverage is used, the lid of folding especially automatically straight down.

Background technology

At present, the lid folding of generally acknowledging will initiatively be turned on, cover tightly and just can be achieved the goal by staff, and because lid separates with bottleneck when opening, loses easily.General lid folding is automatically lost easily, gives and uses its people to cause trouble.

Summary of the invention

In order to overcome the folding automatically of existing lid, the deficiency of losing easily, the utility model provides a kind of lid, and the automatic folding cover of dust of this gravity can not only automatic open close cover, and lid can not lost.

The technical solution adopted for the present invention to solve the technical problems is: in the indentation, there that has on the body of breach, lid, weight block link to each other by hard thick stick, hard thick stick can freely rotate in breach by the rotating shaft that is fixed on the body indentation, there that has breach, the body bottom that has breach links to each other with threaded cap, and threaded cap communicates with body inside.Specifically comprise the body (5) that has breach, have the rotating shaft (2) of the breach edge on the body (5) of breach, hard thick stick (3) links to each other with lid (1) on the hard thick stick (3) by rotating shaft (2), the lower end links to each other with weight block (4), and body (5) lower end that has breach links to each other with threaded cap (6).

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: hard thick stick (3) upper end links to each other with lid (1), and the lower end links to each other with weight block (4), and thick stick (3) is fixed in the rotating shaft (2) firmly, and weight block (4) overweights lid (1) far away.

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: the hard thick stick (3) by rotating shaft (2) and on lid (1) and weight block (4) around the shaft (2) freely rotate.

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: it is that weight block (4) drives hard thick stick (3) and lid (1) (2) rotation around the shaft provides between the motor area that there are a gap regions, gap regions in body (5) upper end that has a breach.

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: body (5) gap regions that has breach links to each other with the body that has breach (5) inner pipe wall, and body (5) inner space that has breach and the space outerpace of gap regions are separated.

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: threaded cap (6) links to each other with the body that has breach (5) lower end, threaded cap (6) communicates with the body that has breach (5) inside.

Described in the utility modelly a kind ofly be used to prevent dust, the lid of folding automatically, wherein: threaded cap (6) under shed, screw thread is arranged in the lid, make threaded cap (6) can spiral cover on common bottleneck, the automatic folding cover of dust of whole gravity is fixed on the bottleneck.

The beneficial effects of the utility model are, can automatic open close cover, prevent that lid from losing, and made things convenient for life, reduced trouble, functional component adopts weight block, and is simple in structure.

Description of drawings

The present invention is further described below in conjunction with accompanying drawing.

Fig. 1 is the utility model plane structure chart.

Fig. 2 is the utility model three-dimensional structure diagram.

Among Fig. 1: 1. lid, 2. rotating shaft, 3. hard thick stick, 4. weight block 5. has the body of breach, 6. threaded cap.

The specific embodiment

In Fig. 1, lid (1) links to each other with the upper end of hard thick stick (3), hard thick stick (3) links to each other with weight block (4) by dead sheave (2) posterior end, the breach edge, upper end that has breach body (5) is fixed in rotating shaft (2), have that breach body (5) is inner to be separated with the breach external environment condition, have breach body (5) lower openings and link to each other and communicate in threaded cap (4).

Tightly at common bottle mouth position, when the people uses bottle,, make the automatic folding cover of dust lid of this gravity hard thick stick drive the lid motion, lid is opened by rotating shaft owing to weight block is subjected to terrestrial attraction sensing the earth's core along with the inclination of bottle.When the people set level bottle, weight block made hard thick stick rotate equally, and lid closes, and had reached the dustproof and anti-lost purpose of automatic folding.
