Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present invention with reference to the drawings is intended to explain the general inventive concept and should not be construed as limiting the invention.
Referring to fig. 1, a pressure switch 100 according to one embodiment of the present invention is shown. The pressure switch 100 comprises a contact switch 101 and means 102 for actuating the contact switch. The contact switch 101 and the device 102 are movably connected to each other. As shown in connection with fig. 2, the device 102 for actuating the contact switch includes the connecting block 8, a pushing assembly and a restoring assembly, both of which are accommodated in an inner cavity of the connecting block 8. In one example, the connecting seat 8 is a hollow cylinder, and those skilled in the art will appreciate that the connecting seat may be provided in other shapes, such as a hollow rectangular parallelepiped, a hollow square cube, and the like. This example is only an illustrative example and those skilled in the art should not be construed as a limitation of the present invention. In one example, an opening (not shown) is provided on a side surface of the connector holder 8 at a position corresponding to the roller 16 of the contact switch 101, and the roller 16 is inserted into the connector holder 8 through the opening. In one example, the contact switch is any one of the contact switches in the prior art.
Referring to fig. 1-3, the pushing assembly includes a first sealing ring 2, a blocking sleeve 3, a second sealing ring 4, a retainer ring 5, a plunger sleeve 6, a plunger 7 and a switch ejector rod 9. The return assembly comprises a spring 10, a screw 11 and a nut 12. The first sealing ring 2, the blocking sleeve 3, the second sealing ring 4, the check ring 5, the plunger sleeve 6, the switch ejector rod 9, the spring 10 and the screw 11 are sequentially arranged in an inner cavity of the connecting seat 8. The plunger sleeve 6 is sleeved on one end, close to the first sealing ring, of the plunger 7, the other end of the plunger 7 is in contact connection with one end of the switch ejector rod 9, and the other end of the switch ejector rod 9 is sleeved with a spring 10.
as shown in fig. 2 and 3, the switch plunger 9 has a slope 91, the slope 91 is provided on one end of the switch plunger 9 near the plunger 7, the roller 16 and the slope 91 are in contact with each other, and the roller 16 is reciprocally swung in a side direction or a radial direction of the connection holder 8 (i.e., moved back and forth between the contact switch 101 and the device 102) by means of the slope 91. Those skilled in the art will understand that the inclined plane can also be disposed at both ends of the switch ejector rod 9, as long as the roller 16 can perform side-direction reciprocating swing on the inclined plane 7 near one end of the plunger 7, this example is only an illustrative example, and those skilled in the art should not understand that the design of the inclined plane can be adjusted accordingly as required by those skilled in the art for a limitation of the present invention.
in one example, two ends of the spring 10 are respectively sleeved on the switch ejector rod 9 and the screw 11, and one end of the screw 11 far away from the spring 10 extends to the connecting seat 8 and is fixed on the connecting seat 8 through the nut 12. In one example, the contact switch is fixed on the outer surface of the connection base 8 by a nut 14 and a screw 15. It will be appreciated by those skilled in the art that the contact switch 101 may also be secured to the device 102 by means of adhesive, welding, etc., and this example is merely an illustrative example and those skilled in the art may substitute existing techniques as desired.
in one example, four screws 1 are provided at one end of the connection socket 8 near the first sealing ring 2 for supporting the device 102. In one example, the end of the coupling socket 8 where the screw 1 is located is connected to a hydraulic pump (not shown) which pumps fluid into the coupling socket 8 to drive the push assembly to move the roller 16.
The specific structure of the pressure switch is further described below by describing the principles of the pressure switch 100 in detail.
When fluid enters the connecting seat 8 of the pressure switch 100 through the hydraulic pump, the fluid cannot flow outwards because the first sealing ring 2, the blocking sleeve 3 and the second sealing ring 4 are arranged to block the fluid in the blocking sleeve 3. As the fluid flowing into the connecting seat 8 increases, the pressure in the connecting seat 8 increases gradually, so that the fluid can only push the plunger 7 to move towards the direction of the reset assembly along the height direction of the connecting seat 8, and further push the switch push rod 9 to move towards the direction of the reset assembly at the same time. Since the roller 16 of the contact switch 101 is disposed on the inclined surface 91 of the switch plunger 9, at this time, the switch plunger 9 is made to push the roller 16 to move from the connection holder 8 toward the direction of the contact switch (arrow direction shown in fig. 4), when the roller 16 presses the button of the contact switch (disposed on the outer surface of the body of the contact switch, disposed corresponding to the roller 16), the contact switch is turned on, and thus, the contact switch is enabled to transmit a signal to the outside.
Because switch ejector pin 9 moves towards reset assembly, simultaneously because the setting of screw 11 and nut 12 for the end of spring 10 is spacing, and then makes spring 10 produce elastic deformation and compress. When the hydraulic pump stops inputting fluid and releases pressure, the elasticity of the spring 10 is larger than the pressure of the fluid at the moment, so that the spring returns to the initial state, the plunger is further pushed to move towards the blocking sleeve 3, the roller 16 is not influenced by external force at the moment, the button of the contact switch returns to the initial position due to no pressure, the roller 16 is driven to reset at the same time, and the closing of the contact switch is realized.
according to the utility model provides a device and pressure switch of drive contact switch have that pressure is adjustable, the signal is stable, cut straightly the formula installation and make simple to operate and need not advantages such as rotatory, small in size.
Although a few embodiments of the present general inventive concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
