Detailed Description
The present invention will be described in detail with reference to the drawings, and it should be understood 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.
As shown in fig. 1-3, a gland dismounting tool comprises a detachable hexagonal head 1 and a rocker 2, wherein the hexagonal head 1 is matched and clamped with an inner hole on the outer side of a gland 7, a polygonal inner hole is formed on the outer side of the hexagonal head 1, one end of the rocker 2 is matched with the inner hole on the hexagonal head 1, and the rocker 2 is clamped with a locking mechanism through a mounting end 23 of the rocker 2; the mounting end 23 of the rocker 2 is radially provided with a mounting hole 21, and the locking mechanism is arranged in the mounting hole 21. The removable hexagonal head 1 is matched with the glands 7 of different pump types to meet the dismounting and mounting work of various pump type glands.
Preferably, the polygonal inner hole on the hexagonal head 1 is a square hole, and the mounting end 23 of the rocker 2 is matched with the square hole on the hexagonal head 1.
Further, locking mechanism includes, welding pin 5, spring 3 and steel ball 4, welding pin 5's one end fixed connection is in mounting hole 21, and the other end is connected with the one end of spring 3, the other end and the steel ball 4 of spring 3 are inconsistent, steel ball 4 block is in mounting hole 21.
It should be noted that the fixed end of the welding pin 5 is connected to one end of the mounting end of the rocker 2 in the mounting end mounting hole 21 by welding, so that the welding pin 5 and the mounting end 23 of the rocker 2 are connected into a whole. One end of the mounting hole 21, which is far away from the welding pin 5, is a stepped hole, and the inner diameter of the outer side of the stepped hole is smaller than that of the mounting hole 21. Because the diameter of the steel ball 4 is larger than the inner diameter of the outer side of the stepped hole and is matched with the inner diameter of the mounting hole 21, the steel ball 4 is clamped in the mounting hole 21 and can move in the mounting hole 21; meanwhile, when the spring 3 recovers to deform and pushes the steel ball 4 to be positioned at the end part of the stepped hole, part of the spherical surface of the steel ball 4 extends out of the port of the stepped hole; when the rocker 2 is manually held and the hexagonal head 1 is forcibly inserted, the inner wall of the hole in the hexagonal head 1 generates extrusion force on the steel ball 4 at the mounting end of the rocker 2, the steel ball 4 extrudes the spring 3 to shrink, the steel ball 4 moves towards the inner side of the mounting hole 21 and is inconsistent with the inner wall of the hole in the hexagonal head 1, the spring 3 plays roles of telescopic adjustment and supporting the steel ball 4, the steel ball 4 plays a role of rolling friction, and the rocker 2 is favorably and rapidly inserted into the square hole in the hexagonal head 1, so that the labor is saved and the convenience is realized.
After the rocker 2 is installed, the pressure support steel ball 4 generated due to the fact that the spring 3 needs to restore deformation is abutted to the inner wall of the hole of the hexagonal head 1, friction is generated, and therefore the locking and fixing effects are achieved, and the separation of the hexagonal head 1 and the rocker 2 is prevented.
The utility model discloses in, rocker 2 is zigzag structure, and this structure is good operation when rotating rocker 2, and is laborsaving moreover. Preferably, the mounting end 23 of the rocker 2 is of a square head structure and is matched with a square hole on the hexagonal head 1. Preferably, a pipe sleeve 6 is sleeved at one end, away from the square head, of the rocker 2, an annular groove 22 is formed in the rocker 2, and the pipe sleeve 6 is positioned through the annular groove in the rocker 2, so that the pipe sleeve 6 does not fall off. Furthermore, the end part of the pipe sleeve 6 is radially provided with a flange extending inwards, the flange is circumferentially arranged around the inner side of the pipe sleeve 6 and is connected with the pipe sleeve 6 body into a whole. The turned-over edge on the pipe sleeve 6 is clamped with the annular groove on the rocker 2, so that the pipe sleeve 6 is positioned, and the pipe sleeve 6 is prevented from falling off from the rocker 2.
