Abstract
The utility model discloses a hydraulic automatic locking device, comprising a small door, a locking oil cylinder, a handle, an oil cylinder fixing seat and a push plate, wherein the oil cylinder fixing seat is fixed on the side wall of the hydraulic automatic locking device, the locking oil cylinder is fixed below the oil cylinder fixing seat, the tail end of the locking oil cylinder is connected with the handle, one end of the handle is connected with the locking oil cylinder, and the other end of the handle is connected with the push plate which is connected with the small door. By adoption of the technical scheme disclosed by the utility model, the hydraulic automatic locking device integrating the respective advantages of a handle type locking device and an air-inflation type locking device is provided, with adoption of a semi-handle semi-air-inflation locking manner, the hydraulic oil cylinder is high in pressure and large in locking force during locking, and the sealing performance is good; and the risks in polluting a sterilizing room are reduced greatly.
Description
Technical field
The utility model relates to a kind of forced locking device, more particularly, relates to a kind of hydraulic automatic locking device that is used on the freeze dryer.
Background technology
Freeze dryer wicket locking device in the industry cycle has two kinds of handle type locking and inflatable lockings.Its shortcoming: the handle type locking method is a kind of a kind of locking method of pure manpower type, and because handle is many, little door switch is very painstaking, consuming time, is not suitable for the fully automatic operation pattern; It is that a kind of needs provide compressed air to carry out a kind of method of gas-flow closure locking for the inflatable locking method, because the gas that is charged into is in desinfection chamber, so the required precision to the machining accuracy of seal groove and sealing ring is all very high, otherwise the risk of polluting the desinfection chamber environment is arranged.
The utility model content
The purpose of this utility model aims to provide a kind of hydraulic automatic locking device, solves the various deficiencies that exist in the prior art.
According to the utility model, a kind of hydraulic automatic locking device is provided, comprise wicket, locking cylinder, handle, oil cylinder fixing base, push pedal.Oil cylinder fixing base is fixed in the sidewall of hydraulic automatic locking device, and locking cylinder is fixed in the below of oil cylinder fixing base, the terminal connecting handle of locking cylinder, and handle one end connects locking cylinder, and the other end connects push pedal, and push pedal connects wicket.
According to an embodiment of the present utility model, the outside of locking cylinder coats one deck outer envelope.
According to an embodiment of the present utility model, handle adopts hexagon socket head cap screw to be connected with locking cylinder.
According to an embodiment of the present utility model, between push pedal and the wicket dedusting sealing ring is set.
According to an embodiment of the present utility model, also comprise oil pressure station and oil pipeline.The oil pressure station is connected with locking cylinder by oil pipeline, to the locking cylinder fuel feeding.
According to an embodiment of the present utility model, oil cylinder fixing base adopts interior hexagonal flat head bolt to be connected with hydraulic automatic locking device.
Adopted the technical solution of the utility model, a kind of hydraulic automatic locking device that combines handle type and inflatable locking device advantage separately is provided, adopt the semi-pneumatic locking mode of semi-handle, pressure is high when making hydraulic jack locking, coupling mechanism force is large, good seal performance; Can greatly reduce the contaminated risk of desinfection chamber.
Description of drawings
In the utility model, identical Reference numeral represents identical feature all the time, wherein:
Fig. 1 is the structural representation of the utility model hydraulic automatic locking device.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
With reference to Fig. 1, forced locking device is used for fastening wicket at freeze dryer during bifurcation bifurcation of the present utility model, so the utility model mainly comprises the gate 10 of freeze dryer, the wicket 11 of freeze dryer, locking cylinder 12, oil cylinder fixing base 13, handle 14, push pedal 15.
As shown in Figure 1, oil cylinder fixing base 13 is fixed in the sidewall of hydraulic automatic locking device, and locking cylinder 12 is fixed in the below of oil cylinder fixing base 13, the terminal connecting handle 14 of locking cylinder 12, handle 14 1 ends connect locking cylinder 12, and the other end connects push pedal 15, and push pedal 15 connects wicket 11.
As shown in Figure 1, the outside of locking cylinder 12 coats one deck outer envelope 16, can prevent that like this utility model hydraulic automatic locking device inside from leaking, and causes the work of locking cylinder 12 undesired.In addition, handle 14 adopts hexagon socket head cap screw to be connected with locking cylinder 12, and oil cylinder fixing base 13 adopts interior hexagonal flat head bolt to be connected with hydraulic automatic locking device.Between push pedal 15 and the wicket 11 dedusting sealing ring 19 is set, when wicket 11 closes, can greatly reduces the contaminated risk of desinfection chamber.
The inside of the utility model hydraulic automatic locking device also is provided with oil pressure station and oil pipeline (not shown in Figure 1).The oil pressure station is connected with locking cylinder 12 by oil pipeline, to locking cylinder 12 fuel feeding.
The working method of hydraulic automatic locking device of the present utility model is: at closing time, provide pressure by the oil pressure station, make locking cylinder 12 make the retraction action, the handle 14 of pulling wicket 11, i.e. wicket 11 lockings.Locking cylinder 12 is made the emersion action when opening the door, and promotes simultaneously the push pedal 15 of wicket 11, and namely wicket 11 is opened.
Those of ordinary skill in the art will be appreciated that above specification only is one or more embodiments among the numerous embodiment of the utility model, and is not to use restriction of the present utility model.Any for the above embodiment equalization variation, modification and be equal to the technical schemes such as alternative, as long as meet connotation scope of the present utility model, all will drop in the scope that claims of the present utility model protect.
