Description

Floor spring rotating shaft structure

Technical Field

The utility model relates to a floor spring field specifically is a floor spring pivot structure.

Background

The floor spring is a hydraulic door closer, except that the device for compressing the spring is a worm gear instead of a rack and pinion. Since the worm wheel can rotate in forward and reverse directions, the floor spring can be used for a door which is opened in both directions. The floor spring is widely applied to enterprises and public institutions such as hotels, office buildings, government units and the like.

However, the floor spring can only control the opening and closing of a single door, in some application scenarios, two or more doors may exist at the same time, one of the doors is opened or closed, and the other doors are also required to be opened or closed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: a floor spring rotating shaft structure is designed and applied to a door body, and the situation that one door is opened or closed and other doors are synchronously opened or closed can be met under the condition that a plurality of doors exist.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a floor spring pivot structure, pivot structure includes the axostylus axostyle, it is protruding that the axostylus axostyle top has the pivot, the lower extreme of axostylus axostyle runs through floor spring casing lower surface, the lower extreme of axostylus axostyle has coupling mechanism, through coupling mechanism realizes a plurality ofly the linkage of floor spring pivot.

Preferably, the rotating shaft structure is further provided with a circular cover plate, the cover plate is divided into an upper cover plate and a lower cover plate, the upper cover plate is sleeved on the upper portion of the shaft rod, and the lower cover plate is sleeved on the lower portion of the shaft rod. Preferably, the upper cover plate and the lower cover plate are provided with round holes matched with the shaft rod in size, screw holes are formed in the two sides of the upper cover plate and the two sides of the lower cover plate, and screws penetrate through the screw holes and are fixedly connected with the floor spring shell.

Preferably, a sealing ring is arranged at the position where the cover plate is contacted with the shell.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a run through the below to the casing with the pivot from the top of floor spring casing, can be so that the pivot can rotate simultaneously from top to bottom.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the rotating shaft structure includes a shaft lever 1, the top end of the shaft lever 1 has a rotating shaft protrusion 11, the rotating shaft protrusion 11 is fixedly connected to the door body (the mounting structure is well known to those skilled in the art, and therefore, other joints between the door body and the door frame are not described in detail), the lower end of the shaft lever 1 penetrates through the lower surface of the floor spring housing 2, the upper end and the lower end of the shaft lever 1 are coaxially disposed, when the door body rotates, the rotating shaft protrusion 11 rotates with the door body, the lower end of the shaft lever 1 is coaxial with the rotating shaft protrusion 11, so that the lower end of the shaft lever 1 rotates with it, the lower end of the shaft lever 1 is connected to the lower ends of the shaft levers 1 of the floor springs mounted on other door bodies through a connecting mechanism (not shown in the figure), and thus, a plurality.

The pivot structure still is provided with circular apron 3, and circular apron 3 divide into upper cover plate 31 and lower apron 32, upper cover plate 31 cup joints the upper portion of axostylus axostyle 1, apron 32 cup joints down the lower part of axostylus axostyle 1, upper cover plate 31 with apron 32 has the round hole that matches with axostylus axostyle 1 size down, upper cover plate 31 both sides with the both sides of apron 32 are equipped with screw hole 4 down, and the screw is worn to locate in screw hole 4 and 2 fixed connection of floor spring casing, the position department that apron 3 and casing 2 contacted is provided with the sealing washer, and apron and sealing washer can strengthen device's stability and waterproof, dustproof performance.

The working principle is as follows: taking the application scene of two doors as an example, two doors respectively with two floor spring pivot mechanism's protruding 11 fixed connection of pivot, the lower extreme of two floor spring's axostylus axostyle 1 passes through coupling mechanism to be connected, when promoting one of them door, the protruding 11 of pivot can rotate along with the door body, the lower extreme of axostylus axostyle 1 is coaxial with the protruding 11 of pivot, so the lower extreme of axostylus axostyle 1 can rotate thereupon, drives another floor spring axostylus axostyle 1 simultaneously and rotates, realizes that another door rotates in step.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
