Description

A nitrogen spring maintenance puller

technical field

The utility model relates to a nitrogen spring maintenance puller, which belongs to the technical field of maintenance equipment.

Background technique

In the maintenance process of nitrogen gas springs, the existing method is to screw a T-shaped handle with a thread at one end into the internal thread of the piston, and then manually pull the piston to the position where the circlip can be taken out, but this method is particularly laborious and the specifications The bigger it is, the more difficult it is, and it can't even be pulled out, and the force cannot be kept constant during the pulling process, which is easy to cause damage to the nitrogen gas spring.

Utility model content

The technical problem to be solved by the utility model is to provide a nitrogen spring maintenance puller, which can easily control the position where the piston is pulled out of the cylinder body, and reduce the difficulty of maintenance; and the piston is drawn smoothly in a straight line, which can avoid damage to the piston and cylinder body .

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A nitrogen spring maintenance puller, comprising a base plate, one end of the base plate is provided with a fixing plate for fixing the nitrogen gas spring, the other end is provided with a drawing plate, the drawing plate is provided with a threaded sleeve, and the threaded sleeve A threaded rod is arranged in the center, one end of the threaded rod is connected with the nitrogen gas spring through a connecting column, and the other end is provided with a hand wheel.

The aforementioned nitrogen spring maintenance puller is characterized in that: the fixing plate is provided with an opening, and at least one positioning ring is arranged in the opening, and the nitrogen spring is fixed on the fixing plate through the positioning ring superior.

The aforementioned nitrogen spring maintenance puller is characterized in that: the threaded rod is connected to the connecting column through a connecting bolt.

The aforementioned nitrogen spring maintenance puller is characterized in that: the threaded rod is connected to the handwheel through a round key.

The beneficial effects of the utility model are: the position where the piston is pulled out of the cylinder body can be easily controlled by turning the threaded rod, and the maintenance difficulty is reduced; the piston is drawn smoothly in a straight line, which can avoid damage to the piston and the cylinder body; Buckle, suitable for maintenance of products of various specifications, simple operation, time-saving and labor-saving, high efficiency.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings of the description.

As shown in Figures 1 and 2, a nitrogen spring maintenance puller includes a base plate 1, one end of the base plate 1 is provided with a fixing plate 2 for fixing the nitrogen gas spring 10, and the other end is provided with a drawing plate 3, so The drawing plate 3 is provided with a threaded sleeve 7, the threaded sleeve 7 is provided with a threaded rod 4, one end of the threaded rod 4 is connected with the nitrogen spring 10 through a connecting column 5, and the other end is provided with a hand wheel 8 .

By turning the hand wheel 8 to drive the threaded rod 4 to move horizontally, the position where the piston is pulled out of the cylinder can be easily controlled, reducing the difficulty of maintenance; and the piston is pulled out in a straight line to avoid damage to the piston and the cylinder.

In this embodiment, the threaded rod 4 is connected with the hand wheel 8 through the round key 11 , which ensures the synchronous rotation of the threaded rod 4 and the hand wheel 8 .

The fixed plate 2 is provided with an opening, and at least one positioning ring 9 is arranged in the opening, and the nitrogen spring 10 is fixed on the fixed plate 2 through the positioning ring 9, and the positioning rings 9 can be interlocked , can be applied to the maintenance of various products of different specifications, easy to operate, save time and effort, and high efficiency.

The threaded rod 4 is connected with the connecting column 5 through the connecting bolt 6, and the length of the connecting bolt 6 is shorter than the opening length of the connecting column 5, so that the connecting bolt 6 is put into the opening to be connected with the threaded rod 4.

To sum up, the utility model provides a nitrogen spring maintenance puller, which can easily control the position where the piston is pulled out of the cylinder, reducing the difficulty of maintenance; and the piston is drawn smoothly in a straight line, which can avoid damage to the piston and the cylinder.
