However, the existing bushing is inconvenient to disassemble, assemble and replace.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a liner structure which is easy to install and convenient to replace, aiming at the current situation of the prior art.

The technical scheme adopted by the utility model for solving the technical problems is as follows: an easy-to-install gasket structure, comprising a gasket body, characterized in that: a strip-shaped hole is formed in the side wall of the liner body along the length direction, and the front end and the rear end of the strip-shaped hole are communicated with the outside respectively.

As an improvement, the hole pitch of the strip-shaped holes is 0.01-0.1 mm.

And then, improving, wherein a thread groove is formed on one side wall of the strip-shaped hole of the gasket body, a cutting groove is formed in the position, where the strip-shaped hole is, on the outer side wall of the gasket body, a through hole is formed in the bottom of the cutting groove, and a screw connected with the thread groove is arranged at the through hole.

And the outer side wall of the gasket body is provided with a plurality of screws at intervals along the length direction of the strip-shaped hole.

And the outer side wall of the gasket body is provided with a dismounting groove.

And the two disassembly and assembly grooves are oppositely arranged.

And in the improvement, a spigot groove is arranged on the end wall of the inner hole at one end of the gasket body.

And the other end of the gasket body is provided with an insert, the inner end of the insert is connected with the gasket body, and the outer end of the insert is clamped in the shell of the pistol drill.

Compared with the prior art, the utility model has the advantages that: according to the utility model, the strip-shaped holes are formed in the outer side wall of the gasket body, so that when the gasket body is installed, the gasket body can generate elastic deformation with larger modulus at the strip-shaped holes, the gasket body can be opened, and after the rotating shaft is installed, the rotating shaft can be clamped again by the gasket body, so that the gasket body can be opened and closed in the assembling and disassembling process, and the gasket is convenient to assemble and has the characteristics of easiness in installation and convenience in replacement.

FIG. 1 is a schematic diagram of a construction of an easy-to-install liner structure in an embodiment of the present invention;

fig. 2 is another schematic view of an easily installed spacer structure according to an embodiment of the present invention.

Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 and 2, the gasket structure easy to mount in the present embodiment includes a gasket body 1, a screw 2, and an insert 3.

Wherein, seted up bar hole 11 along length direction on the 1 lateral wall of liner body, the front end and the rear end of bar hole 11 link up with outside mutually respectively, and preferably, the hole interval of bar hole 11 is at 0.01~0.1 mm.

Further, a thread groove is formed in one side wall of the strip-shaped hole 11 of the gasket body 1, a cutting groove 12 is formed in the position, where the strip-shaped hole 11 is located, of the outer side wall of the gasket body 1, a through hole is formed in the bottom of the cutting groove 12, a screw 2 connected with the thread groove is arranged at the position of the through hole, after the gasket body 1 is clamped into the rotating shaft, the two side walls of the strip-shaped hole 11 in the gasket body 1 are connected through the screw 2, and the gasket body 1 is prevented from being opened in the strip-shaped hole 11 when in use. Preferably, a plurality of screws 2 are provided on the outer side wall of the gasket body 1 at intervals along the length direction of the strip-shaped hole 11.

In addition, in order to facilitate the installation and the removal of the gasket body 1, the outer side wall of the gasket body 1 is provided with a dismounting groove 13, so that the gasket body 1 can be dismounted by using the dismounting groove 13. Preferably, dismouting recess 13 has two to be arranged relatively, through two dismouting recesses 13 of alternate effect for gasket body 1 can remove along the pivot, avoids unilateral effect dismouting recess 13, causes gasket body 1 to block the pivot.

In addition, in the embodiment of the utility model, the end wall of the inner hole at one end of the gasket body 1 is provided with the spigot groove 14, and when the gasket body 1 is installed, the spigot groove 14 is abutted against the shaft shoulder of the rotating shaft, so that the gasket body 1 is stably installed.

Finally, be provided with inserts 3 at the liner body 1 other end, inserts 3's the inner links to each other with liner body 1, and inserts 4's outer end card is gone into in the pistol drill casing, like this, realizes spacing the liner body 1 other end, and simultaneously, inserts 3 can also avoid outside dust to get into in the liner body 1.

In summary, the outer side wall of the gasket body 1 is provided with the strip-shaped hole 11, so that when the gasket body 1 is installed, the gasket body 1 can elastically deform with a larger modulus at the strip-shaped hole 11, the gasket body 1 can be opened, and after the rotating shaft is installed, the rotating shaft can be clamped again by the gasket body 1, so that the gasket body 1 can be opened and closed in the assembling and disassembling process, and the gasket is convenient to assemble and has the characteristics of easiness in installation and convenience in replacement.
