It connects, plunger rod, which moves up, can push chain guide mobile, tighten chain on chain guide, play the work of tensioner chain
With, guaranteeing the transmission effect of chain, the lateral wall lower end of the plunger rod is equipped with recess circle, and recess is enclosed for placing sealing ring,
Sealing ring 8 is cased on the recess circle, sealing snare contacts with the inner sidewall of plunger channel in recess circle, can be avoided liquid
Pressure oil is leaked out from plunger channel, and compressed spring 9 is equipped between the lower surface of the plunger rod and the bottom surface of plunger channel,
Compressed spring is connected to before plunger rod and plunger channel, can pull downward on plunger rod, and the lateral wall right part of the plunger rod is set
There is a limiting slot 10, limiting slot and limit plunger are met cooperation, are limited the moving range in plunger channel of plunger rod, are kept away
Exempt from plunger rod to deviate from from plunger channel, the right side wall top of the pedestal is equipped with position-limiting drum 11, and position-limiting drum is for accommodating limit
Plug, limit plunger can be taken out, remove the limitation to plunger rod, the inside of the position-limiting drum from position-limiting drum when needed
Equipped with the limit plunger 12 for running through pedestal, limit plunger is extend into limiting slot, to the moving range in plunger channel of plunger rod into
It has gone limitation, has avoided plunger rod from deviating from from plunger channel, the right end of the position-limiting drum is threaded with limited cover 13, limited cover
Limit plunger is fixed in position-limiting drum by the right end covered in position-limiting drum, guarantees the limit effect of limit plunger, can will be limited when needing
Lid is removed, and limit plunger therein is taken out, and the lateral wall left end of the plunger rod is equipped with rack gear 14, in the lower end surface level of rack gear
End slope, rack gear move up and down together with plunger rod, and rack gear moves up plunger rod and do not have an impact, when plunger rod is downward
When mobile, rack gear can mutually be limited with the engaging tooth on clamping block, when plunger rod can not move down, pedestal described in upper surface
Upper left end is equipped with the first groove 15, and the first groove rotates, described first is recessed therebetween for components such as clamping blocks for clamping block
The bottom surface of slot is connected with one end of snap-springs 16, and snap-springs push up clamping block, and engaging tooth is enable to be embedded into rack gear
In the middle, the other end of the snap-springs is connected with clamping block 17, is equipped with main engaging tooth 18, institute on the upside of the right end of the clamping block
It tells and is equipped with secondary engaging tooth 19 on the downside of the right end of clamping block, main engaging tooth plays the role of that plunger rod is prevented to withdraw, secondary engaging tooth master
It plays the main engaging tooth of guidance to be embedded into rack gear, avoids the phenomenon that generating apical tooth, running through before and after the middle part of the clamping block and setting
There is pin shaft 20, be rotatablely connected between the rear and front end and pedestal of the pin shaft, clamping block can be rotated around pin shaft, snap-springs
The left end that will push clamping block moves up, and the engaging tooth of the right end of clamping block can then be embedded into rack gear, and plunger rod is starting
When machine starting is flame-out or when chain reaction force is retracted, engaging tooth is set to be embedded into stress in rack gear, main card by snap-springs effect
Shape has a certain degree between conjunction tooth, plunger rod and pin shaft, can more be embedded into rack gear when main engaging tooth stress is withdrawn and work as
In, plunger rod is subject to downward force bigger, and the active force of engaging tooth is also bigger, and avoid plunger rod from withdrawing, and traditional stopper,
Traditional stopper will receive plunger to the power being displaced outwardly, the trend that the bigger stopper of strength is displaced outwardly is also bigger,
It is easy to cause stopper to deviate from, loses the effect of non-return.
Specifically, the left end of the clamping block is equipped with handle 21, when needed, handle is pressing fastened convenient for user
Block rotates counterclockwise clamping block, deviates from clamping block from rack gear.
Specifically, the right end of the limit plunger and limited cover is equipped with protrusion block 22, protrusion block is convenient for user to limit
Position plug and limited cover are operated, and limit plunger and limited cover are installed and dismantled.
Specifically, being symmetrically arranged with the second groove 23, the lateral wall front end of the plunger rod before and after the upper end of the pedestal
Equipped with the first fixed projection 24, the lateral wall front end of the pedestal is equipped with the second fixed projection 25, before the lateral wall of the pedestal
End is hinged with fixed link 26, and the fixed link is equipped with fixed gap 27, can be by turning fixed link when plunger rod is withdrawn
The position towards the first fixed projection is moved, by fixed gap by the fixed top of plunger rod, avoids plunger rod from stretching out, normally makes
With fixed link is then rotated the position towards the second fixed projection when device, fixed link is fixed, the position of fixed link is avoided
Operation of the moving influence to vehicle.
Working principle: mounting hole is passed through by bolt, chassis is fixed on vehicle, device is fixed on vehicle
On, mouth is added with hydraulic oil in the pipeline that hydraulic oil is provided in vehicle and is connect, hydraulic oil can be passed in vehicle launch
In plunger channel, the upper end of plunger rod connect with external chain guide, when vehicle launch, hydraulic oil can be passed to plunger and lead to
In road, providing tension to plunger rod moves up plunger rod, pushes chain guide mobile, tightens chain on chain guide,
Play the role of tensioner chain, guarantees that the transmission effect of chain, the process that plunger rod moves up not will receive on clamping block
The influence of engaging tooth, when engine start stops working, plunger rod will receive the power of compressed spring when stop solution Pressure oil feeder, there is receipts
The trend in plunger channel is returned to, the reaction force of chain is also will receive in vehicle operation, makes to engage by snap-springs effect
Tooth is embedded into stress in rack gear, and shape has a certain degree between main engaging tooth, plunger rod and pin shaft, withdraws in main engaging tooth stress
When can more be embedded into rack gear, plunger rod is subject to downward force bigger, and the active force of engaging tooth is also bigger, avoids plunger
Bar is withdrawn, even if producing certain abrasion to main engaging tooth, but as long as there is no angle between main engaging tooth, plunger rod and pin shaft
Close to the non-return effect that can guarantee at right angle to plunger.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
