Abstract
The utility model discloses an automatic resetting device of a lifting rotary shaft, which comprises a fixed body provided with a first cylinder and a rotating body. Two opposite first V-shaped notches are arranged on the first cylinder, two opposite first bosses are arranged between the two opposite first V-shaped notches and provided with first platforms, and the width of the first V-shaped notches is gradually increased from inside to outside. The rotating body is provided with second bosses and second V-shaped notches, the second bosses and the second V-shaped notches are respectively matched with the first V-shaped notches and the first bosses correspondingly. By means of the structure and corresponding matching of the first V-shaped notches and the first bosses and the second bosses and the second V-shaped notches, when a door is opened, the rotating body rotates relative to the fixed body, dislocation between the second bosses and the first V-shaped notches occurs, and the second bosses slide off along with the first V-shaped notches under the gravity action of the door, thereby achieving automatic resetting. The automatic resetting device of the lifting rotary shaft is convenient to use and maintain, simple in structure and low in production cost.
Description
Technical field
The utility model relates to a kind of automatic reset device.
Background technology
Present many households and office are with all being equipped with automatic reset device in the door, so that use.In the prior art, this automatic reset device is generally driven by calutron or spring assembly, the structure more complicated, and cost is high, safeguards very inconvenience.
Summary of the invention
The technical problem that the utility model will solve provides a kind of automatic reset device simple in structure, reduces cost, and is convenient to safeguard.
In order to solve the problems of the technologies described above; A kind of lift shaft automatic reset device of the utility model; Comprise fixed body and rotor, have first cylinder on the said fixed body, have two first relative V-notchs on this first cylinder; Between two first V-notchs two first relative boss; Have first platform on this first boss, the said first V-notch width increases from the inside to the outside gradually, and said rotor is provided with respectively second boss and second V-notch with first V-notch, the first boss corresponding matching.
As the improvement of technique scheme, said fixed body arranged outside has the side projection, and this side projection is coated with protective cover.
As the improvement of technique scheme, said side projection both sides have the L shaped groove that is used to clamp protective cover.
The beneficial effect of the utility model is: this lift shaft automatic reset device is owing to adopt said structure, and through the corresponding matching of first V-notch, first boss and second boss and second V-notch, rotor relative fixed body rotates when door is opened; Second boss and first V-notch misplace, and under the deadweight effect of door, second boss is along with the first V-notch landing; Realization automatically resets, and is easy to use, and simple in structure; Be convenient to safeguard that cost of production is lower.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is one of structural representation of fixed body;
Fig. 3 be fixed body structural representation two;
Fig. 4 is the structural representation of rotor.
The specific embodiment
Referring to figs. 1 through Fig. 4; A kind of lift shaft automatic reset device of the utility model; Comprise fixed body 1 and rotor 2, have first cylinder 3 on the said fixed body 1, have two first relative V-notchs 4 on this first cylinder 3; Between two first V-notchs 4 two first relative boss 5; Have first platform 6 on this first boss 5, said first V-notch, 4 width increase from the inside to the outside gradually, and said rotor 2 is provided with respectively second boss 7 and second V-notch 8 with first V-notch 4, first boss, 5 corresponding matching.This lift shaft automatic reset device is owing to adopt said structure, and through the corresponding matching of first V-notch, first boss and second boss and second V-notch, rotor relative fixed body rotates when door is opened; Second boss and first V-notch misplace, and under the deadweight effect of door, second boss is along with the first V-notch landing; Realization automatically resets, and is easy to use, and simple in structure; Be convenient to safeguard that cost of production is lower.
In the present embodiment; Said fixed body 1 arranged outside has side projection 9; This side projection 9 is coated with protective cover, and side projection 9 is respectively arranged with the screw of regulating its position, through in side projection both sides mounting screw it is fixed; When needs adjustment fixed body angle, as long as just can through regulating both sides screw degree of tightness.Side projection 9 is coated with protective cover, can avoid screw offside projection to cause wearing and tearing.
For the ease of installing and fixing of protective cover, said side projection 9 both sides have the L shaped groove 10 that is used to clamp protective cover, and the protective cover both sides are bent to the shape with L shaped groove corresponding matching, just can snap in then wherein, and are easy to operate.
The above is merely the preferential embodiment of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the utility model.
