Description
Technical field
The utility model belongs to mechanical vacuum equipment technical field, is related to a kind of vacuum pump, more particularly to a kind of vacuum pump
Electrical retractor on pedestal pull rod.
Background technology
Vacuum pump refers to be obtained to being evacuated by pumping container using machinery, physics, chemically or physically chemical method
The device or equipment of vacuum, for popular, vacuum pump is to improve, generate and maintain true in a certain enclosure space with various methods
Empty device.The effect of vacuum pump is exactly that gas molecule is extracted from vacuum chamber, reduces the indoor gas pressure of vacuum, is allowed to reach
To the vacuum degree of requirement.In order to which vacuum pump is made easily to move, wheel and pull rod generally on the pedestal of vacuum pump are installed, and passed
Its pull rod of the vacuum pump of system generally stretches manually, although being manufactured into background, pull rod is easily loosened walks about frequently in personnel
Place easily trip.
The content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one kind with motor controlling party
Just the electrical retractor on vacuum pump frame pull rod used.
The purpose of this utility model can be realized by following technical proposal：Electronic on a kind of vacuum pump frame pull rod stretches
Compression apparatus, including connecting rod, push rod, casing and the motor being arranged in casing, which is characterized in that the both ends of the casing are set respectively
Upper cover plate and lower cover are equipped with, the motor is fixed on lower cover, is consolidated on the axis of the motor by wearing pan head screw
Screw is connected with, the pushing rod sleeve is arranged on screw and the inside of push rod has and the matched helicla flute of screw, the push rod
To be pierced by upper cover plate outer and be fixedly connected with connecting rod at top.
Electrical retractor its technique effect on this vacuum pump frame pull rod is：Telescopic device, which is symmetrical arranged, is fixed on bottom
On seat, connecting rod is connected with pull rod, and by the flexible of the flexible drive pull rod of connecting rod, motor operation drives the screw on its axis
Rotation, is coordinated between screw and push rod by helicla flute, therefore push rod stretches out and drives connecting rod when motor positive operation, similarly
It will shrink connecting rod when motor reversely rotates, so as to fulfill the Telescopic of pull rod, compared with traditional hand pull rod, sheet
Electrical retractor can be easy to use by switching the positive and negative operation of one-touch control motor, and electrodynamic type can make pull rod
Retracted position it is deeper there is no concern that can not be drawn out, can make in design vacuum pump volume increase it is compact.
In electrical retractor on a kind of above-mentioned vacuum pump frame pull rod, between the upper cover plate and lower cover
Casing internal is provided with connection strap, the upper end of the connection strap sets limit switches, and the bottom of the push rod is provided with
Connector is fixed with and the matched limited block of limit switch on the connector.
Motor rotation is excessive in order to prevent, by the design of limit switch when push rod reaches certain position, bottom
Limited block by touch limit switch leave the motor off operation, increase its security.
Compared with prior art, the electrical retractor on this vacuum pump frame pull rod has more convenient to use and makes true
The advantages of design volume of sky pump is compacter.

On, screw 7 is fixed with by wearing pan head screw on the axis of motor 4, push rod 2 is sheathed on screw 7 and the inside of push rod 2 has
With 7 matched helicla flute of screw, the top of push rod 2 is pierced by outside upper cover plate 5 and is fixedly connected with connecting rod 1.
It further describes in detail, motor 4 rotates excessively in order to prevent, is located between upper cover plate 5 and lower cover 6 inside casing 3 and sets
It is equipped with connection strap 8, the upper end of connection strap 8 sets limit switches 9, and the bottom of push rod 2 is provided with connector 10, on connector 10
It is fixed with and 9 matched limited block 11 of limit switch.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although connecting rod 1, push rod 2, casing 3, motor 4, upper cover plate 5, lower cover 6, screw 7, company is used more herein
The terms such as narrow bars 8, limit switch 9, connector 10, limited block 11, but it does not preclude the possibility of using other terms.Use this
A little terms are used for the purpose of more easily describing and explaining the essence of the utility model；It is construed as any additional
Limitation is all contrary to the spirit of the present invention.
