Abstract
The utility model provides an anti-loose round nut. The anti-loose round nut comprises a lock net. The anti-loose round nut is characterized by further comprising thrust blocks and tightening set screws. The inner lateral wall of the lock net is provided with grooves. Radial threaded holes are arranged on the lateral wall of the lock net. The tightening set screws are arranged in the threaded holes. The thrust blocks match with the grooves. The thrust blocks are part of the lock net. The height of the thrust blocks is the same as the height of the lock net. The number of the grooves is the same as the number of the thrust blocks and is one or more than one. The threaded holes are interconnected with the center of the bottom portions of the grooves. The anti-loose round nut is directly transformed from a round nut and is convenient to process. When a component is arranged on a positioning shaft, no key grooves are needed to be arranged in the positioning shaft, and an axial space and a radial space of the positioning shaft are saved. The problem that a locking cushion is disabled after the locking cushion is dismounted a plurality of times does not exist, the looseness problem in the using process of the round nut is solved and working efficiency is improved.
Description
Technical field
The utility model relates to the mechanical component field, relates in particular to a kind of fastening piece.
Background technique
At present, the location of parts on shaft round nut commonly used and the round nut stop pad supporting with it wherein have interior stop ear and outer stop ear on the round nut stop pad.During assembling, in the groove on the stop ear insertion axle in the packing ring, and the outer stop ear of packing ring is embedded in the groove of round nut, round nut namely is locked, and just can not get loose owing to the rotation of axle in use.Round nut and round nut stop pad are simple in structure, and it is convenient to buy, but dismounting is inconvenient, and just can lose efficacy through round nut stop pad after the several times dismounting.In addition, the installation of round nut stop pad need to be offered keyway at axle, has greatly weakened the intensity of axle, and the axial space that this just need to add macro-axis has increased design difficulty.For the restricted axle spare of the radial space of axle, radial dimension can't strengthen, and should not offer keyway, and the application of round nut is restricted.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of locking round nut, comprise locknut, characterized by further comprising thrust block, Cock screw, described locknut madial wall is provided with groove, and sidewall is provided with tapped hole radially, and tapped hole and bottom portion of groove connect, described Cock screw is positioned at described tapped hole, described thrust block and described groove coupling.
Described thrust block is the part of described locknut.
The height of described thrust block is identical with the height of described locknut.
The number of described groove and described thrust block is identical, and is more than 1 or 1.
Described tapped hole and described bottom portion of groove through.
The beneficial effects of the utility model are: formed by direct transformation of round nut, and the not restriction of the position of groove, easy to process; When locating parts on shaft, need not to offer keyway on the axle, can not weaken the intensity of axle, and saved the axial and radial space of axle, reduced design difficulty; In addition, locknut, Cock screw, thrust block are used in conjunction with, and need not to use the round nut stop pad, convenient disassembly, and the problem that just lost efficacy after not existing the round nut stop pad to dismantle has several times solved the loosening problem of round nut in using process, has improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation, as depicted in figs. 1 and 2,1-locknut, 2-thrust block, 3-Cock screw, 4-groove, 5-tapped hole.
Cut out square groove 4 with the line cutting mode at locknut 1 madial wall, and obtain thrust block 2 with groove 4 coupling, also attack tapped hole 5 radially, that connect with groove 4 bottom centre on locknut 1 sidewall, Cock screw 3 is positioned at tapped hole 5, the height of thrust block 2 is identical with the height of locknut 1, and the number of groove 4 and thrust block 2 is 1.
Example:
During use, first thrust block 2 is placed in the groove 4, again locknut 1 is screwed on the double-screw bolt that matches, the Cock screw 3 that then will be engaged in the tapped hole 5 is tightened, just thrust block 2 is ejected a part, lock by thrust block 2 thereby make between double-screw bolt and the locknut 1, replaced the round nut stop pad, and can prevent the loosening of round nut using process.
Above an embodiment of the present utility model is had been described in detail, but described content only is better embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
