Description

Air supporting fixed shaft

Technical Field

The utility model relates to the technical field of air support installation, in particular to an air support fixing shaft.

Background

The air support is commonly called as an air spring, and is widely applied to occasions of door body opening and closing control, two ends of the air support are connected with a door body and a door frame through a fixed shaft respectively, wherein the air support is connected with the fixed shaft through a spherical hinge, the non-spherical hinge end of the fixed shaft is connected with the door frame through a screw or a bolt, but the connecting hole position of the bolt connecting end of the existing fixed shaft is fixed, the situation that butt joint hole positions on the door frame are different is difficult to be applied to, in short, the application range of the existing fixed shaft is small, in addition, the lubrication effect of the connecting part of the fixed shaft and the air support is poor, and the dry grinding problem can occur in a period of use.

To this end, the utility model provides an air bearing fixed shaft.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide an air support fixing shaft so as to solve the problems in the background art.

In order to achieve the above object, the present utility model is realized by the following technical scheme: the utility model provides a gas props fixed axle, includes the axis body, and the one end of this axis body is provided with the bulb, the other end fixedly connected with mounting disc of axis body has seted up a plurality of waist hole on the quotation of this mounting disc, and the distance in the both ends and the mounting disc center of this waist hole is different.

Further, the number of the waist-shaped holes is at least three and is uniformly distributed along the circumferential direction of the mounting plate.

Further, the waist-shaped hole is arc-shaped.

Further, anti-skid protruding points positioned on two sides of the waist-shaped hole are arranged on the disc surface of the mounting disc adjacent to the shaft body.

Furthermore, a lubrication cavity is formed in the shaft body, and a channel communicated with the lubrication cavity is formed in the ball head.

Further, the outer peripheral wall of the shaft body is fixedly connected with a nipple.

The beneficial effects of the utility model are as follows:

1. the shaft body can be abutted with the external synchronous mounting holes through bolts or screws by arranging the plurality of waist-shaped holes which are obliquely distributed on the mounting plate, so that the fixing shaft has the advantage of improving the application range of the fixing shaft.

2. By arranging the lubrication cavity in the shaft body, the shaft body has the function of storing lubricating oil, and the ball body of the shaft body is provided with a channel communicated with the lubrication cavity, so that the lubrication of the ball body and the air supporting ball shell is improved.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1 and 2, the present utility model provides a technical solution: the utility model provides a gas props fixed axle, includes axis body 1, the one end of this axis body 1 is provided with bulb 11, bulb 11 and the one end ball hinge connection of gas props, the other end fixedly connected with mounting disc 2 of axis body 1, mounting disc 2 passes through the bolt and is connected with the installation face, a plurality of waist type hole 21 has been seted up on the quotation of this mounting disc 2, waist type hole 21 is screw or bolted connection hole, the both ends of this waist type hole 21 and the distance difference in the center of mounting disc 2, this kind of setting makes axis body 1 adapt to the installation environment that the mounting hole is apart from different, improves the suitability.

In this embodiment, the number of the waist-shaped holes 21 is at least three and is uniformly distributed circumferentially relative to the mounting plate 2, and after bolts or screws are mounted in the three waist-shaped holes 21, the mounting of the mounting plate 2 is more fastened.

In this embodiment, the waist-shaped hole 21 is arc-shaped, and this arrangement can improve the centering of the mounting plate 2 after the mounting surface is abutted, that is, the shaft body 1 is located at the middle position of the three connection points in the waist-shaped hole 21, so as to improve the mounting centering.

In this embodiment, the disc surface of the mounting disc 2 adjacent to the shaft body 1 is provided with anti-slip protruding points 22 located at two sides of the waist-shaped hole 21, and when the bolt or the screw is extruded on the surface of the mounting disc 2, the anti-slip protruding points 22 play a loosening role.

In this embodiment, a lubrication cavity 12 is formed in the shaft body 1, a channel 13 which is communicated with the lubrication cavity 12 is formed in the ball head 11, lubrication grease is stored in the lubrication cavity 12, when the ball head 11 and a ball shell at one end of the air support are hinged together, the lubrication oil supplements and lubricates the ball hinge, wherein a grease nipple 3 is fixedly connected to the peripheral wall of the shaft body 1, and the grease nipple 3 is a grease filling port.

Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
