Abstract

The utility model discloses an anti-loosening and anti-rusting locking cap which is applied for locking spare parts of machinery. A screw hole is arranged at the side wall of a hexnut, and is vertical to the central line of the hexnut; a bolt is arranged in the screw hole; one end surface of the hexnut is welded with a cylindrical sleeve; the inner diameter of the sleeve is larger than the diameter of the hexnut by 2-8mm; the upper part of the sleeve is provided with a bottom; the screw hole is arranged on the sleeve; and an oil nozzle is fixedly arranged in the screw hole. The anti-loosening and anti-rusting locking cap has the effects of tightly compressing the locking nut on the bolt, and having good anti-loosening effect; moreover, the bolt and thread of the anti-loosening and anti-rusting locking cap can resist rusting, save time and effort during mounting and maintenance, prolong the service life of the bolt, are simple to be operated, and are convenient to be maintained. Corrosion of bad environments on the bolts and threads and damage on the threads caused by improper operation are avoided. The anti-loosening and anti-rusting locking cap can reduce the working intensity of operating personnel and reduce the maintenance cost.

Description

Locking, the anti-locking cap of embroidering
Technical field
The utility model relates to component of machine technique for fixing field, and particularly a kind of screw rod, bolt end are antirust, is locking, the anti-locking cap of embroidering in a kind of screw rod, bolt end.
Background technique
A lot of machinery need fixing for a long time in the open or park.In oil field equipment, the part on the equipment generally adopts Bolt Connection, for guaranteeing to connect reliably, prevents to become flexible locking device all is housed, as compression spring, cotter pin, double nut etc.Wherein most widely used on main equipment still is double nut, in this anti-loose structure, it is loosening easily that relatively common faults is mounted in the lock nut that screws the nut upper end, thereby lose the pretension effect, the equipment of the more important thing is often is under the severse weathers such as dust storm, rainwater, the screw thread of bolt end is exposed for a long time externally, and screw thread is easily by corrosion; In addition, operate, improperly when safeguarding cause screw thread damage, influence the normal use of bolt.The production scene is often met the long-term corrosion rear thread of bolt place and is ruptured, and because of screw thread damage and corrosion, causes bolt to change difficulty during operator's service equipment, has to carry out cutting operations such as electric welding, causes the waste of material resources and manpower.
The model utility content
The purpose of this utility model is: a kind of locking, anti-locking cap of embroidering is provided, solves the loosening problem of set screw nut of equipment attachment bolt; Solve the bolt end and embroider the erosion problem, improve the set screw nut safety reliability, reduce maintenance cost and labor intensity of operating personnel.
The technical solution adopted in the utility model is: locking, the anti-locking cap of embroidering, mainly form by oil nozzle, sleeve, hexagon nut and screw, it is characterized in that: sidewall and vertical hexagon nut center line at hexagon nut have a screw, and a screw is arranged in screw; Be welded with a cylindrical sleeve on an end face of hexagon nut, sleeve diameter is greater than 2~8 millimeters of the diameters of thread of hexagon nut, and upper cartridge has the end, and screw is arranged on sleeve, and the screw internal fixation has oil nozzle.
At the sleeve top screw is arranged, described oil nozzle is to be fixed in the screw at sleeve top.
Radially screw is arranged on sleeve wall, and described oil nozzle is to be fixed in the radially screw of sleeve wall.
Locking, the anti-locking cap working principle of embroidering: consult Fig. 1.Fixing bolt 7 passes the fixed block 5 on the equipment, and set screw nut 6 is fixed on the fixing bolt 7, in the air that the end of fixing bolt 7 exposes.Adopt locking, the anti-hexagon nut 3 of embroidering locking cap is spun on the fixing bolt 7, and hexagon nut 3 is pressed on the upper-end surface of set screw nut 6.Screw screw 4, the inner of screw 4 and fixing bolt 7 outer walls are fixing tight, and hexagon nut 3 can not become flexible.Because sleeve 2 can protect fixing bolt 7 injury-free for the tube of sealing.By oil nozzle 1, in sleeve 2, inject grease, can play fixing bolt 7 end anti-corrosion protective actions.
The beneficial effects of the utility model: the utility model is locking, the anti-locking cap of embroidering, the set screw nut on can hold-down bolt, and anti-loosing effect is good, the bolt thread anti-corrosion, it is time saving and energy saving to install, safeguard, prolongs bolt working life, simple to operate, easy to maintenance.Avoid rugged environment to the corrosion of bolt thread and the damage of the improper double thread of operation.Can reduce labor intensity of operating personnel, reduce maintenance cost.
Description of drawings
Fig. 1 is locking, the anti-locking cap structural profile schematic representation of embroidering of the utility model.
Among the figure, 1. oil nozzle, 2. sleeve, 3. hexagon nut, 4. screw, 5. fixed block, 6. set screw nut, 7. fixing bolt.
Embodiment
Embodiment 1: with locking, an anti-embroidery locking cap is example, and the utility model is described in further detail.
Consult Fig. 1.This locking, anti-embroidery locking cap is the fixing bolt 7 at M36.Locking, anti-embroidery locking cap mainly is made up of oil nozzle 1, sleeve 2, hexagon nut 3 and screw 4.Screw in that the sidewall and vertical hexagon nut 3 center lines of the standard hex nut 3 of M36 * 3 have a M8 has a M8 screw 4 in screw; On the upper-end surface of hexagon nut 3, be welded with a cylindrical sleeve 2,40 millimeters of sleeve 2 internal diameters.The end of 6 millimeters thick, arranged at sleeve 2 tops, at the bottom of the top of sleeve 2 screw arranged, and the screw internal fixation has oil nozzle 1.The distance on the last plane of the lower plane of oil nozzle 1 and fixing bolt 7 is 5 millimeters.
Embodiment 2.Substantially the same manner as Example 1, difference is: it is to be fixed in the radially screw of sleeve 2 walls that a radially screw, oil nozzle 1 are arranged on sleeve 2 walls.
