Abstract
The utility model discloses a device for opening and closing a manual gate, which comprises a gate plate, a screw rod, a gate handwheel, a rope, a fixed pulley and a counterweight body. The device utilizes pulling force generated by the counterweight body to reduce force which is required for opening and closing the heavy gate plate, and the device has the advantages of being simple to manufacture, being convenient to use and being capable of saving manpower.
Description
Technical field
The utility model relates to a kind of valve system, more particularly, relates to a kind of hand door headstock gear.
Background technology
At present some gates are to realize opening and closing to gate by action of gravity, and screw mandrel is installed on the flashboard, assemble handwheel on the screw mandrel, drive screw mandrel to promote or the landing flashboard by rotating handwheel.But, when the weight of flashboard is too heavy, only manually just can not finish opening and closing to gate with manpower, usually need be by other machinery or power equipment.
Summary of the invention
The technical problems to be solved in the utility model is, at the prior art deficiency, provides a kind of making simple, easy to use and reliable, can be easily device by manually opened and closed shutter.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of hand door headstock gear, include flashboard, screw mandrel, gate handwheel, flashboard top is connected with screw mandrel, the gate handwheel is installed on screw mandrel top, the screw mandrel top is connected with rope, and rope passes fixed pulley and connects balance weight body.
The weight of described balance weight body is 50% ~ 70% of flashboard weight.
Compared with prior art, the beneficial effect that the utility model had is: the utility model utilizes the principle of fixed pulley two ends stress balance, the balance weight body that one section rope that passes fixed pulley connects heavy flashboard and constant weight respectively is set, the pulling force that relies on balance weight body to form alleviates the required strength of the heavy flashboard of opening and closing, making just can light opening and closing gate by general Manpower operating, reaches effect laborsaving, handled easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises flashboard 1, and flashboard 1 top connects screw mandrel 2, and screw mandrel 2 tops are provided with gate handwheel 3, and rope 4 two ends connect screw mandrel 2 and balance weight body 6 respectively and pass fixed pulley 5.When the needs starting gate, Rotary grate handwheel 3 drives screw mandrel 2 and promotes flashboard 1, greatly alleviates because most of weight of flashboard 1, promotes flashboard 1 required strength by the weight balancing of balance weight body 6, and Rotary grate handwheel 3 is by manually can easily finishing.When the needs closed shutter, backward rotation gate handwheel 3 drive screw mandrels 2 put down flashboard 1 and can finish.
The weight of balance weight body 6 can be chosen as 50% ~ 70% of flashboard 1 weight according to actual needs in the utility model.With a common adult is example, the common scope of exerting oneself is in tens kilograms of scopes, the weight of supposing flashboard 1 is 30 kilograms, add the frictional resistance that produces between each parts, promoting flashboard 1 required strength can obviously increase and cause the starting gate difficulty, has assembled after weight is the balance weight body 6 of flashboard weight 50% ~ 70%, and most of weight of flashboard 1 is by balance weight body 6 balances, the strength that promotes flashboard 1 is in tens, 20 kilograms of scopes, and common adult is starting gate easily.Simultaneously, the weight of balance weight body 6 should not surpass 70% of flashboard 1 weight, when the weight difference between balance weight body 6 and the flashboard 1 is too little during near frictional resistance, will cause being difficult to put down flashboard.
Claims (2)
1. a hand door headstock gear includes flashboard, screw mandrel, gate handwheel, and flashboard top is connected with screw mandrel, and the gate handwheel is installed on screw mandrel top, it is characterized in that described screw mandrel top is connected with rope, and rope passes fixed pulley and connects balance weight body.
2. hand door headstock gear according to claim 1 is characterized in that, the weight of described balance weight body is 50% ~ 70% of flashboard weight.
