The bolt of corrosion and the connection structure of screw thread are insecure for a long time, and disassembly is more difficult in maintenance of equipment.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of detachable antirust bolts, solve to exist in the prior art
Bolt easily get rusty, destroy connection fastness, the problem for causing disassembly difficult.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of detachable antirust bolt, including bolt head and screw rod, the inner hub location of the bolt head are provided with recessed
Slot, the middle position of the groove are provided with circular hole, and push-and-pull component is provided in the circular hole, and the push-and-pull component includes pushing away
Bar, one end of the push rod pass through the circular hole and are provided with a push top, and the other end is connected with a rubber plug, the inside of the screw rod
It is provided with Oil Guide channel, oil outlet is arranged at intervals on the outer wall of the screw rod, the oil outlet is connected to the Oil Guide channel,
The oil outlet and the channel attached port of the Oil Guide are taper, and the screw rod is connect with the groove by screw thread rotation,
And sliding up and down the rubber plug in the Oil Guide channel, the length of the push rod is less than or equal to the length in the Oil Guide channel
Degree.
Preferably, the outer diameter of push top described above is greater than the diameter of the circular hole, the push top and the push rod one
It forms or is detachably connected.
The beneficial effects of the utility model are: the bolt of the utility model, structure is simple, is by bolt head and screw design
It is detachable, it refuels convenient for the dismounting and change of bolt head and out of Oil Guide channel；It, can will be in Oil Guide channel by pushing and pulling component
Lubricating oil be more effectively pushed into oil outlet, thus on bolt body and the part that need to be connected the screw thread age of a draught animal carry out antirust
Processing, meanwhile, it in use, can also similarly be operated, bolt and part junction are lubricated, bolt is prevented
It gets rusty, guarantees the connection fastness of bolt and part, be also convenient for subsequent dismounting and change.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the fractionation structural representation of the utility model.
In figure: 1- bolt head；2- screw rod；3- push rod；4- push top；5- rubber plug；21- Oil Guide channel；22- oil outlet.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figs. 1-2, a kind of detachable antirust bolt, including bolt head 1 and screw rod 2, the inside center position of bolt head 1
It installs and is equipped with groove 11, the middle position of groove 11 is provided with circular hole, and push-and-pull component is provided in circular hole, and push-and-pull component includes pushing away
Bar 3, one end of push rod 3 pass through circular hole and are provided with a push top 4, and the other end is connected with a rubber plug 5, and screw rod 2 is internally provided with
Oil Guide channel 21 is arranged at intervals with oil outlet 22 on the outer wall of screw rod 2, and oil outlet 22 is connected to Oil Guide channel 21, oil outlet 22
The port connecting with Oil Guide channel 21 is taper, and screw rod 2 is connect with groove 11 by screw thread rotation, and keeps rubber plug 5 logical in Oil Guide
It is slided up and down in road 21, the length of push rod 3 is less than or equal to the length in Oil Guide channel 21.In use, first push-and-pull component is installed on
On bolt head 1, make rubber plug 5 close to circular hole, then fill lubricating oil in Oil Guide channel 21, due to oil outlet 22 and Oil Guide channel
The port of 21 connections is taper, and the lubricating oil in Oil Guide channel 21 can seldom be flow to certainly in oil outlet 22, then screw rod 2 is rotated and is connected
It is connected in groove 11, presses down push rod 3 finally by push top 4, squeeze into the lubricating oil in Oil Guide channel 21 in oil outlet 22, it is right
Bolt and part carry out antirust treatment, when not having lubricating oil in Oil Guide channel 21, push rod 3 are up pulled out, due to the original of air pressure
Cause, moreover it is possible to enhance the adsorption capacity between bolt and part, improve connection fastness between the two.The bolt of the utility model, knot
Structure is simple, bolt head 1 and screw rod 2 are designed as it is detachable, convenient for the dismounting and change of bolt head 1 and out of Oil Guide channel 21
It refuels；By pushing and pulling component, the lubricating oil in Oil Guide channel 21 can be more effectively pushed into oil outlet 22, thus to bolt body
And the screw thread age of a draught animal on the part that need to be connected carries out antirust treatment, meanwhile, in use, can also similarly it be grasped
Make, bolt and part junction are lubricated, prevent bolt from getting rusty, guarantees the connection fastness of bolt and part, after being also convenient for
Continuous dismounting and change.
The outer diameter of push top 4 is greater than the diameter of circular hole, and push top 4 is integrally formed or is detachably connected with push rod 3.Above-mentioned design,
Push top 4 can be made to have certain sealing effect for circular hole, improve the using flexible and validity of product.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
