Abstract
The utility model discloses an elongated sleeve, which comprises a sleeve body, wherein the length of the sleeve body is 120mm, one end of the sleeve body is provided with an extending hole for a screw rod to extend into, the end part of the outer end of the extending hole is a hexagonal hole, and the hexagonal hole is used for being matched with a nut; the other end of the sleeve body is provided with a four-corner hole which is used for being matched with the plate body. This scheme is through with sleeve body extension to set up in inside and stretch into the hole and let the screw rod of rail stretch into and stretch into downtheholely, the nut is entangled to the hexagonal hole on the rethread, and inserts the plate body downthehole rotation that goes on in four corners, in order to realize the dismantlement and the installation to the nut on the rail screw rod, simple structure, the practicality is strong.
Description
Technical Field
The utility model relates to a sleeve specifically is for adding elongated sleeve.
Background
At present, most of sleeves in the market are short in length, so that nuts on the bolts cannot be disassembled and assembled, and the practicability is poor.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides an add elongated sleeve has solved the problem of mentioning in the background art.
(II) technical scheme
In order to achieve the above object, the utility model provides a following technical scheme:
the lengthened sleeve comprises a sleeve body, the length of the sleeve body is 120mm, one end of the sleeve body is provided with an extending hole for a screw to extend into, the end part of the outer end of the extending hole is a hexagonal hole, and the hexagonal hole is used for being matched with a nut; the other end of the sleeve body is provided with a four-corner hole which is used for being matched with the plate body. This scheme is through with sleeve body extension to set up in inside and stretch into the hole and let the screw rod of rail stretch into and stretch into downtheholely, the nut is entangled to the hexagonal hole on the rethread, and inserts the plate body downthehole rotation that goes on in four corners, in order to realize the dismantlement and the installation to the nut on the rail screw rod, simple structure, the practicality is strong.
Preferably, the connection part of the adjacent hole walls of the hexagonal hole and the four-corner hole is an inwards concave arc-shaped groove.
Preferably, the grooves are 3/8 "gauge and the hexagonal holes have a 12mm (or variable size) diameter.
(III) advantageous effects
The utility model provides an add elongated sleeve. The method has the following beneficial effects:
the utility model discloses a with sleeve body extension to set up in inside and stretch into the hole and let the screw rod of rail stretch into and stretch into downtheholely, hexagonal hole entangles the nut on the rethread, and inserts the downthehole rotation in four corners with the plate body, with the dismantlement and the installation of the nut on the realization on to the rail screw rod, simple structure, the practicality is strong.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the sleeve comprises a sleeve body 1, a sleeve body 2, an extension hole 3, a hexagonal hole 4, a quadrangular hole 4 and a groove 5.
Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.
As shown in fig. 1, the utility model provides a technical solution: the lengthened sleeve comprises a sleeve body 1, the length of the sleeve body 1 is 120mm, one end of the sleeve body 1 is provided with an extending hole 2 for a screw to extend into, the end part of the outer end of the extending hole 2 is a hexagonal hole 3, and the hexagonal hole 3 is used for being matched with a nut; the other end of the sleeve body 1 is provided with a four-corner hole 4, and the four-corner hole 4 is used for being matched with a plate body. This scheme is through with sleeve body 1 extension to in seting up in inside and stretching into hole 2 and let the screw rod of rail stretch into and stretch into hole 2, 3 entangle nuts in the hexagonal hole on the rethread, and insert the plate body and rotate in the tetragonal hole 4, in order to realize the dismantlement and the installation to the nut on the rail screw rod, simple structure, the practicality is strong.
Preferably, the joint of the adjacent hole walls of the hexagonal hole 3 and the quadrangular hole 4 is an inward concave arc-shaped groove 5.
Preferably, the groove 5 has a gauge of 3/8 "and the hexagonal hole 3 has a hole diameter of 12mm (or variable size).
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
