Time occurs that loose or long phenomenon crossed by chain after using, and to alleviate the noise of electromotor, improves precision and longevity that transmitter runs
Life.
Stretcher is the degree of tightness being regulated chain by guide chain rail, owing to chain work process being in dynamically, and electromotor
Rotating speed will affect the elasticity of chain, so stretcher is also a dynamic regulation during regulation, but current
Stretcher compensates the stretcher support to chain by return spring merely, it is impossible to guarantee compensation precision, and to guide pillar bullet
After being adjusted of power, elasticity can strengthen, can tension to the correction of chain, it is impossible to accurately control intensity and distance, affect chain
Transmission effect, long time running also can increase the abrasion of chain, reduces service life；And existing engine chain tensioner
Being all single part with guide chain rail, the part of its assembling is more, and management difficulty is relatively big, and during assembling, stretcher does not has locking machine yet
Structure, assembling difficulty, it is therefore necessary to improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of engine chain tensioning
Device, it have can accurately control intensity and distance, increase the service life, assemble simplicity, part easily manages and reduces cost
Feature.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of engine chain tensioner,
Including housing and guide pillar, being provided with cavity in described housing, described guide pillar is installed in cavity；Described guide pillar is hollow structure, institute
Being provided with spring in stating guide pillar, the bottom of described cavity is provided with check valve；One end of described spring is connected on check valve；Described
The top of guide pillar is connected by top board guide chain rail；Described guide chain rail is provided with pin-and-hole, and described pin-and-hole is fitted with inserting of locking
Pin；The side of described guide pillar is provided with walking tooth, and described housing is provided with scotch, and described scotch is existed by pin-hinges
On housing；Being provided with groove on described housing, described groove is positioned at the lower section of scotch, is provided with scotch bullet in described groove
Spring, described scotch spring acts on the afterbody of scotch, the end of described scotch be provided be meshed with walking tooth only
Dynamic tooth.
It is provided with fixing hole on described housing.
The side of described housing offers shoe cream room, and described shoe cream room connects cavity by fuel feed hole.
Described shoe cream room is outside equipped with filter screen.
Described check valve includes that valve seat, steel ball and bonnet, described bonnet are arranged on valve seat, and described steel ball is arranged on bonnet
In；It is provided with one-way valve spring between described bonnet and steel ball.
Described top board is provided with the counterbore coordinated with guide pillar plug-in mounting.
Described guide chain rail and latch all use plastic material made.
After using said structure, compared to the prior art this utility model has the advantage, that the letter of this utility model structure
Single, by guide chain rail being arranged on the top board at guide pillar top so that stretcher is united two into one with guide chain rail, can directly withstand
Chain, installs simple, reduces cost；It is inserted in pin-and-hole by latch before Zhuan Pei, so that guide pillar locking, extracts again after assembling
Latch, and by regulation scotch, effectively limit the perimetric length of guide pillar, reach the correction accurately controlling guide pillar to chain
Distance and intensity, make chain operate the most smoothly, and service life is longer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits protection model of the present utility model
Enclose, with embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment, as shown in Figure 1: a kind of engine chain tensioner, including housing 10 and guide pillar 11, is provided with in housing 10
Cavity 12, guide pillar 11 is installed in cavity 12；It is provided with fixing hole 24 on housing 10, is used for installing fixing.Guide pillar 11 is hollow
Structure, is provided with spring 13 in guide pillar 11, the bottom of cavity 12 is provided with check valve；One end of spring 13 is connected on check valve；
Check valve includes valve seat 28, steel ball 29 and bonnet 30, and bonnet 30 is arranged on valve seat 28, and steel ball 29 is arranged in bonnet 30；Valve
One-way valve spring 31 it is provided with between cap 30 and steel ball 29；The side of housing 10 offers shoe cream room 25, shoe cream room 25 pass through into
Oilhole 26 connects cavity 12；Shoe cream room 25 is outside equipped with filter screen 27, owing to guide pillar 11 is less, easily by machine oil with housing 10 gap
In impurity blocking, cause guide pillar 11 clamping stagnation and damping action to lose efficacy, the impurity of certain volume can be foreclosed by filter screen 27,
Effectively prevent this problem from occurring.
During in order to make guide pillar 11 stretch out, during oiling, steel ball 29 overcomes the elastic force of one-way valve spring 31 to be backed down, hydraulic pressure
Oil enters in bonnet 30, bonnet 30 stress, promotes and moves on guide pillar 11, and during guide pillar 11 moves, scotch 19 overcomes stop
The elastic force of block spring 22, deflects certain angle；When oiling stops, steel ball 29 return, hydraulic oil cannot reflux, scotch 19
Stop tooth 23 is mutually clamped with walking tooth 18 so that scotch 19 cannot turn round, and guide pillar 11 also cannot bounce back, and provides steady with this
Fixed tensile force.
The top of guide pillar 11 is connected by top board 14 guide chain rail 15 so that united two into one with guide chain rail 15 by stretcher,
Can directly withstand chain, install simple, reduce cost.Top board 14 is provided with the counterbore coordinated with guide pillar 11 plug-in mounting, guide chain rail 15
It is provided with pin-and-hole 16, pin-and-hole 16 is fitted with the latch 17 of locking；Guide chain rail 15 and latch 17 all use plastic material made, real
Relatively strong by property, cost is relatively low.The side of guide pillar 11 is provided with walking tooth 18, and housing 10 is provided with scotch 19, scotch 19
Hinged on the housing 10 by pin 20；Being provided with groove 21 on housing 10, groove 21 is positioned at the lower section of scotch 19, groove 21
Inside being provided with scotch spring 22, scotch spring 22 acts on the afterbody of scotch 19, the end of scotch 19 be provided with
The stop tooth 23 that walking tooth 18 is meshed.
It is inserted in pin-and-hole 16 by latch 17 before assembling, so that guide pillar 11 locking, after assembling, extracts latch 17 again, and
By regulation scotch 19, effectively limit the perimetric length of guide pillar 11, reach the correction accurately controlling guide pillar 11 to chain
Distance and intensity, make chain operate the most smoothly, and service life is longer.
