Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

The first embodiment is as follows: a spring expansion sleeve pulling device is shown in the attached figure 1 and comprises a hammer rod 1 and a hammer ram 2, wherein one end of the hammer rod 1 is connected with a spring expansion sleeve 10, the other end of the hammer rod 1 is provided with a baffle 13, and the hammer ram 2 is arranged on the hammer rod 1 and slides along the length direction of the hammer rod 1. When the expansion spring sleeve 10 is pulled out, one end of the hammer rod 1 is connected with the expansion spring sleeve 10, then the sliding hammer 2 impacts the baffle 13, the hammer rod 1 can be driven to pull the expansion spring sleeve 10 to move outwards through impact, and the expansion spring sleeve 10 is pulled out through multiple impacts.

Specifically, the hammer rod 1 includes a connecting portion 11 connected to the spring expansion sleeve 10 and a sliding portion 12 on which the hammer 2 slides, and the sliding portion 12 is provided with a baffle 13 at both ends thereof, and specifically, the baffle 13 is fixed on the sliding portion 12.

Specifically, this embodiment still includes connecting plate 3, and connecting plate 3 passes through bolt 4 to be connected on spring sleeve 10 that rises, and hammer stem 1 is connected on connecting plate 3. The bolt 4 is connected to one end of the expanding spring sleeve 10 and is tightly pressed on the end part of the hinge pin through the expanding spring sleeve 10. When the spring expansion sleeve 10 is pulled out, a screw penetrates through the connecting plate 3 and is screwed on the spring expansion sleeve 10, then the connecting part 11 of the hammer rod 1 is connected to the connecting plate 3, the hammer rod 1 is impacted on the baffle 13 at one end far away from the spring expansion sleeve 10 through the sliding of the ram 2, and the spring expansion sleeve 10 is driven to be pulled out outwards through the impact of the ram 2; in some embodiments, the bolt 4 is tightened again after each strike, assisting the ram 2 in extracting the expanding spring sleeve 10 by tightening the bolt 4 against the hinge pin.

Specifically, two bolts 4 are arranged on the connecting plate 3, and screw rod parts of the two bolts 4 are threaded with the expanding spring sleeve 10 after penetrating through the connecting plate 3; the two bolts 4 are symmetrically arranged relative to the axis of the expansion spring sleeve 10, the hammer rod 1 connected to the connecting plate 3 is located in the middle position between the two bolts 4, and the length direction of the hammer rod 1 is arranged along the axis direction of the expansion spring sleeve 10.

Specifically, a nut 5 is arranged on each of the two bolts 4, the head portions of the nut 5 and the bolt 4 compress the connecting plate 3 in the middle, and the connecting plate 3 cannot slide on the bolt 4 due to the arrangement of the nut 5, so that the impact force of the striker 2 impacting on the baffle 13 can be directly transmitted to the bolt 4 through the connecting plate 3.

Specifically, a threaded hole is formed in the connecting plate 3, and the connecting portion 11 of the hammer rod 1 is inserted into the threaded hole and is in threaded fit with the threaded hole. Through the arrangement of the threaded holes, the hammer rod 1 is conveniently and quickly connected to the connecting plate 3.

Specifically, at least one pull ring 21 is fixedly connected to an outer side of the hammer 2, and when the hammer 2 is slid, an operator pushes or pulls the hammer 2 to move through the pull ring 21.

The working principle of the expanding spring sleeve pulling-out device when in use is as follows: when the expansion spring sleeve 10 is pulled out, one end of the hammer rod 1 is connected with the expansion spring sleeve 10, then the sliding hammer 2 impacts the baffle 13, the hammer rod 1 can be driven to pull the expansion spring sleeve 10 to move outwards through impact, and the expansion spring sleeve 10 is pulled out through multiple impacts.

Example two: a spring expansion sleeve pulling device is shown in figure 2, and the difference between the embodiment and the first embodiment is that elastic buffer parts 6 are arranged at two ends of a ram 2, and when the ram 2 approaches a baffle 13, the elastic buffer parts 6 are firstly contacted with the baffle 13; through the arrangement of the elastic buffer 6, when the hammer 2 impacts the baffle 13, impact force can be slowly applied to the baffle 13, and instantaneous impact is prevented from damaging threads at threaded connection parts. Specifically, the elastic buffer 6 is provided as a spring and the elastic buffer 6 is sleeved outside the sliding portion 12. One end of each spring, which is far away from the other end, is fixedly connected with a backing ring 61, and the backing ring 61 is sleeved on the outer side of the sliding part 12.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the fan belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
