Abstract
The utility model discloses an unidirectional advance formula tensioning ware, including valve body end, cylindric lock, plunger, return spring, main part, screw bolt hole and check valve, the valve body end is connected with the check valve, the plunger is connected to the cylindric lock, return spring connects plunger and main part respectively, the plunger is worn to be equipped with in the centre of main part, seted up the screw bolt hole in the main part, and inside valve body end and the check valve of being provided with of main part. This unidirectional advance formula tensioning ware adopts the design of valve body impulse type, and should the design adopt the check valve, utilizes return spring to make this equipment playback voluntarily, avoided still will utilizing the valve body to playback when this equipment of incompatibility, and secondly that the valve body of this equipment adopts laborsaving principle for light the boosting of plunger of this equipment.
Description
Technical field
This utility model relates to mechanical equipment technical field, is specially a kind of one-way propelling stretcher.
Background technology
nullDevelopment along with society，Machinery range in people live is more and more wider，Today the most universal，Almost the vehicles of the reason driven by energy such as its automobile can be can afford in every household，The most in the factory，Also almost all has used the mode of machinery production，In the above，It all can use a kind of equipment，That is exactly electromotor，But it also has a component between electromotor and driving means，That is exactly the chain transmitting kinetic energy，In existing machinery，Chain is utilized kinetic energy to carry out transmission easily，But it the most also can be not enough，First it is exactly during chain works，It can cause chain-loose in the case of daily rotation，Thus coming off of chain can be caused，What is more causes the accident，Therefore the tensioner of a kind of chain is specially have developed in society in order to solve this problem，But existing stretcher is the most not enough，First exactly in the design of valve, device is the most all design two way valve，Therefore on it uses, a kind of useless design is resulted in，Next is exactly that existing equipment manually to playback when not in use，Therefore it is the most very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of one-way propelling stretcher, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of one-way propelling stretcher, including valve body end, straight pin, plunger, return spring, main body, screws bolts hole and check valve, described valve body end is connected with check valve, described straight pin connects plunger, and described return spring connects plunger and main body respectively, and the centre of described main body is equipped with plunger, offer screws bolts hole in described main body, and body interior is provided with valve body end and check valve.
Preferably, described valve body end and check valve are vertically arranged, and valve body end and check valve design for integral type.
Preferably, described plunger design is cylindrical, and the maximum extension elongation of plunger is 18.7cm.
Preferably, a diameter of 8.2cm of described check valve, and the diameter of check valve can change.
Compared with prior art, the beneficial effects of the utility model are: this one-way propelling stretcher, use the design of valve body push type, and this is designed with check valve, return spring is utilized automatically to make this equipment playback, avoid the valve body to be utilized when being not suitable with this equipment to playback, next to that the valve body of this equipment uses laborsaving principle so that the plunger of this equipment is easily boosted.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of one-way propelling stretcher, including valve body end 1, straight pin 2, plunger 3, return spring 4, main body 5, screws bolts hole 6 and check valve 7, valve body end 1 is connected with check valve 7, valve body end 1 and check valve 7 are vertically arranged, and valve body end 1 and check valve 7 design for integral type, straight pin 2 connects plunger 3, plunger 3 is designed as cylinder, and the maximum extension elongation of plunger 3 is 18.7cm, return spring 4 connects plunger 3 and main body 5 respectively, the centre of main body 5 is equipped with plunger 3, screws bolts hole 6 is offered in main body 5, and main body 5 is internally provided with valve body end 1 and check valve 7, the a diameter of 8.2cm of check valve 7, and the diameter of check valve 7 can change.
Operation principle: before suitably this one-way propelling stretcher, first this equipment is bolted the downside being arranged on the chain at actuating device, after Gu Ding, by handling check valve 7 thus the operating of band moving valve end 1, plunger 3 can be moved upward, when plunger 3 motion reaches the position making chain fasten, straight pin 2 is plugged between plunger 3 and main body 5, realize fixing plunger 3, when need not plunger 3 and chain being fastened, only need to take away straight pin 2, plunger 3 meeting automatic homing under the effect of return spring 4, whole process i.e. completes once the work of this one-way propelling stretcher.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
