Abstract

The utility model relates to a transportation roller accessory technical field specifically is a cover is pressed to roller convenient to installation location, the roller is the machinery in the cylinder form can the pivoted object, power supply (for example motor) drive roller commonly used in the machinery, it gos forward to drive other materials, or utilize the roller to produce pressure and process the material, and the roller surface is comparatively fragile, the columniform barrel damages very easily when suffering external force striking, and it needs whole cargo airplane of pause to change the roller, cause very big economic loss so the installation outside the roller presses this problem of solution that the cover can be fine, the utility model provides a pair of cover is pressed to roller convenient to installation location, through at the internal installation location bolt of last sleeve, only need punch the hole in the relevant position of roller, alright prevent to press the cover and take place to sideslip with the roller through the location bolt very convenient, improved work efficiency.

Description

Roller pressing sleeve convenient to install and position

The technical field is as follows:

the utility model relates to a transportation roller accessory technical field specifically is a roller is pressed and is overlapped convenient to installation location.

Background art:

the roller is the cylinder can pivoted object in the machinery, power supply (for example motor) drive roller commonly used in the machinery, drive other materials and advance, or utilize the roller to produce pressure and process the material, and roller surface is comparatively fragile, the columniform barrel damages when suffering external force striking very easily, and change the roller and need suspend whole cargo airplane, so cause very big economic loss to press the cover to be fine the solution this problem of can be fine at the roller outer installation, but the roller presses the cover to have the installation complicated under the prior art, the fixity is poor and the not good scheduling problem of degree of sealing, and press between cover and the roller because the not good frictional force of laminating degree not enough and take place easily to sideslip and cause the reduction of conveying efficiency.

The utility model has the following contents:

the utility model aims at providing a roller is pressed and is overlapped convenient to installation location in order to solve current problem exactly.

The technical solution of the utility model is as follows:

the utility model provides a roller is pressed and is overlapped convenient to installation location, includes upper sleeve and lower sleeve, evenly is provided with the laminating muscle on upper sleeve and the telescopic inner wall down, the center of upper sleeve inner circumferential face is provided with the location bolt, evenly be provided with a plurality of first screws on the wall of upper sleeve's both sides section of thick bamboo, fixed mounting has the nut in the first screw, be provided with the second screw with first screw matched with on the wall of the both sides section of thick bamboo of lower sleeve, be provided with the thread groove on the inner wall of second screw, be provided with the bolt in the second screw, the bolt comprises nut and double-screw bolt, the shaping has the first screw thread with nut matched with on the double-screw bolt, the shaping has the second screw thread with thread groove matched with on the nut.

As the preferred technical scheme, the number of the first screw holes and the second screw holes is 3.

Preferably, the positioning pin is fixed to the center of the inner circumferential surface of the upper sleeve by welding.

As the preferred technical scheme, the upper cylinder sleeve and the lower cylinder sleeve are provided with a convex block and a slot which are connected by a plug bush.

The beneficial effects of the utility model reside in that:

(1) The utility model provides a pair of cover is pressed to roller convenient to installation location through at last sleeve internally mounted location bolt, only needs to punch the hole in the relevant position of roller, alright prevent to press the cover to take place to sideslip with the roller through location bolt very convenient, improved work efficiency.

(2) The screw holes of the upper sleeve and the lower sleeve are internally provided with nuts and threads, and the nuts and the studs of the specially-made bolts are both provided with threads, so that the upper sleeve and the lower sleeve can be well installed and fixed to prevent looseness.

(3) The lugs and the inserting sleeves which are arranged in the upper barrel sleeve and the lower barrel sleeve in a staggered mode enable the pressing sleeves to be connected more tightly, and influence on work due to overlarge gaps is prevented.
