This device simple structure, reasonable in design makes portably, this device is fixed on the box of vacuum, only need tighten lock nut when needs seal up, the threaded rod card advances the locking inslot that corresponds on the chamber door, twist lock nut, can't twist again until lock nut move, the chamber door is locked, the simple operation is sealed up closely.
Description
Technical field
The utility model is related to technical field of lithium-ion battery, more particularly, to a kind of vacuum door locking device.
Background technology
At present, lithium ion battery have the advantages that specific energy is high, recycle often, storage time long, not only just
Take as mobile phone, DV and laptop computer are used widely on formula electronic equipment, and be widely used in electricity
The big-and-middle-sized electrical equipment aspect such as electrical automobile, electric bicycle and electric tool, the therefore safety requirements to lithium ion battery
More and more higher.
For square lithium ion battery therein, mp3, mp4, personal digital assistant, mobile phone, number it have been widely used in
The mobile products such as camera core toy, have that voltage is high, electricity capacity is big, long circulation life, memory-less effect, light weight, work model
The advantages of enclose width.At present, lithium ion battery increasingly develops towards the direction of high power capacity light and thin type.
Vacuum tank is widely applied in lithium ion battery production, when carrying out vacuumizing operation it is necessary to elder generation is chamber door pass
Close, lock, quickly could be extracted into predetermined vacuum values in vacuum tank cavity, otherwise, chamber door not tight leads to gas leakage, then shadow
Ring vacuumizing effect.Therefore how conveniently to lock chamber door it is ensured that vacuumizing effect, become asking of a urgent need to resolve
Topic.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of vacuum door locking device, energy
The chamber door of enough tight seal vacuum tanks.
The utility model for achieving the above object, employs the following technical solutions:
A kind of vacuum door locking device it is characterised in that: include mounting seat, pin, threaded rod and locking nut, institute
State and carry two connecting holes in mounting seat, for fixing with vacuum chamber, be fixed with two connections in the side of described mounting seat
Ear, one end of described threaded rod is located between described two engaging lugs, and described pin sequentially passes through described engaging lug and described
Threaded rod, the two ends of pin are connected to split pin, the other end of described threaded rod and described locking nut screw thread cooperation.
Preferably, the side of described mounting seat is fixed with limiting plate.
Preferably, the surface of described locking nut is provided with wearing layer.
The beneficial effects of the utility model are: with respect to prior art, this apparatus structure is simple, reasonable in design, manufactures letter
Just, this device is fixed on vacuum chamber, only needs to tighten locking nut when needing and being sealed, threaded rod sticks on chamber door
In corresponding locking slot, tightened jack panel, until locking nut cannot turn again, chamber door is locked, simple operation, sealing is tight
Close.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail specific embodiment of the present utility model.In the utility model
Description in it is to be understood that term " " center ", " longitudinal ", " horizontal ", "front", "rear", "left", "right", " vertical ", " water
Flat ", " top ", " bottom " " interior ", the orientation of instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only
It is for the ease of the description present invention and to simplify description, rather than the device of instruction or hint indication or element must have specifically
Orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
As shown in figure 1, a kind of vacuum door locking device, including mounting seat 1, pin 2, threaded rod 3 and locking nut
4, described mounting seat carries two connecting holes, for fixing with vacuum chamber, is fixed with two in the side of described mounting seat
Engaging lug, one end of described threaded rod is located between described two engaging lugs, described pin sequentially pass through described engaging lug and
Described threaded rod, the two ends of pin are connected to split pin 5, and the other end of described threaded rod is joined with described locking nut screw thread
Close.
The side of described mounting seat is fixed with limiting plate 6.Limit the rotational angle of threaded rod 3, prevent locking nut 4 from injuring by a crashing object
Tank surface.
The surface of described locking nut is provided with wearing layer, locking nut surface knurling, is conducive to staff to rotate, non-slip.
Each part just has 45# steel to make, surface hardening, zinc-plated, to increase mar proof and to prevent corrosion.
This apparatus structure is simple, reasonable in design, manufactures easy, this device is fixed on vacuum chamber, is carrying out closing chamber door
When vacuumizing operation, rotation lock nut 4, threaded rod sticks in corresponding locking slot on chamber door, tightened jack panel 4, until lock
Jack panel cannot turn again, chamber door is locked, and now opens vacuum switch, casing starts to vacuumize operation, if as vacuum
Effect locking nut 4 has loosened, and can tighten again.On the contrary, when needing to open vacuum chamber door, locking screw can first be unscrewed
Mother, to nut and chamber door have certain distance when, (now limiting plate 6 plays prevents locking nut from injuring casing by a crashing object to turn on locking nut
Effect), open casing charging valve, to normal pressure, then can open chamber door.
The above is only preferred embodiment of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
