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.

Example 1

Referring to fig. 1-6, the present invention provides a technical solution:

a miniature elastic vacuum buffer comprises a quick mounting sleeve 3, a buffer sleeve 4 and a buffer seat 8;

in implementation, as shown in fig. 2, a circular hole 302 is formed in the surface of the quick mounting sleeve 3, the quick mounting sleeve 3 is sleeved with the expansion sleeve 2, a fastening bead 201 is integrally formed on the inner wall of the expansion sleeve 2, and the fastening bead 201 penetrates through the circular hole 302; one end of the buffer sleeve 4 is integrally formed with a circular tube 402, the circular tube 402 is provided with an annular groove 403, and when the circular tube 402 is completely inserted into the quick mounting sleeve 3, one side of the snap bead 201 can be clamped in the annular groove 403; buffer seat 8's one end integrated into one piece has buffer beam 11, and the upper end of buffer beam 11 slides and pegs graft in buffer sleeve 4, sets up the bar guiding hole 5 that the symmetry set up on buffer sleeve 4, installs guide screw 6 on buffer beam 11 perpendicularly, and guide screw 6 sets up in bar guiding hole 5, and the lower pot head of buffer beam 11 is equipped with spring 7, and the sucking disc 10 is installed through connecting 9 in buffer seat 8's lower part.

Specifically, as shown in fig. 1 to 4, the present embodiment further includes a rotation preventing structure, the rotation preventing structure includes a limiting flat port 401 disposed on the buffering sleeve 4 and a limiting buckle 301 disposed at one end of the quick mounting sleeve 3, and when the buffering sleeve 4 and the quick mounting sleeve 3 are mounted in a butt joint manner, the limiting buckle 301 can be clamped in the limiting flat port 401. This kind of design through preventing gyration structure, can play when this application installation is used and prevent gyration effect.

As shown in fig. 1, in the implementation, one end of the quick-mounting sleeve 3 is integrally formed with the mounting head 1, and the mounting head 1 has an external thread capable of being matched with an equipment actuator (which can be mounted on an equipment actuator of a third party through the mounting head 1, the equipment actuator is a robot end, a module end, and the like, and the whole is in a rod-shaped structure, so that the structure is simple, the micro-structure can be set, and multiple-row mounting and use are realized).

In addition, the expansion sleeve 2 and the snap bead 201 are arranged to be of an integral plastic or rubber structure. The joint 9 and the sucker 10 are arranged into an integral structure, and the joint 9 is installed at the lower end of the buffer seat 8 in a threaded mode. For clearance sliding fit between buffer rod 11 and cushion collar 4, and this clearance is less than 0.05mm, and this clearance is less, only can get into through a small amount of gas, when this application inserts negative pressure installation and uses, and is less to the influence of vacuum.

In practice, one end of the buffer rod 11 extends to the middle of the circular tube 402. The interior of the buffer seat 8 and the interior of the buffer rod 11 are both hollow structures.
