Embodiment Construction
[0016] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] Specific embodiment 1 of the inflation and deflation device of the present invention, as figure 2 As shown, the inflation and deflation device includes a joint clamping piece 1, the joint clamping piece 1 is a rectangular shell, one side of which is an open side, and the side of the joint clamping piece 1 is used to face the joint. The semi-circular bayonet 8 that the annular flange engages with, and the bayonet 8 keeps intersecting with the opening side of the joint clamping member 1 , so that the joint can be clamped in the bayonet 8 through the opening side. The side of the joint clamping part 1 away from the joint has a semicircular protrusion, and the inner cavity of the semicircular protrusion is in communication with the inner cavity of the joint clamping part 1, and the semicircular protrusion is far away from the end surface of the bayon...

The invention provides a gas charging and discharging device, and relates to the technical field of gas charging and discharging devices. The gas charging and discharging device comprises a pushing rod and a joint blocking part, wherein the pushing rod is provided with a pushing rod initial position which is spaced with a valve element, and a pushing rod self-locking position which is jacked and matched with the valve element, and is kept in a self-locking state; an operating mechanism for pushing the pushing rod to switch between the pushing rod initial position and the pushing rod self-locking position is arranged on the pushing rod; the operating mechanism comprises a pushing rod hinged part which is hinged with the pushing rod, and a self-locking connecting rod which is separately hinged with the joint blocking part and the pushing rod hinged part; a hinge axis for the pushing rod hinged part and the self-locking connecting rod and a hinge axis for the pushing rod hinged part and the pushing rod are arranged in a spaced mode in parallel; and a connecting line for two hinge points, which are separately hinged with the joint blocking part and the pushing rod hinged part, on the self-locking connecting rod is parallel to a length direction of the pushing rod while the pushing rod is in the pushing rod self-locking position, so that the pushing rod is kept in the self-locking state. The pushing rod is kept in the self-locking state to prevent the valve element from rebounding and returning, so that the problem that operation wastes time and labor while gas charging and discharging operation is performed on a gas chamber is solved.
Description
technical field [0001] The invention relates to an inflation and deflation device. Background technique [0002] For gas chamber products equipped with G-type joints, the internal pressure of the product may be in a vacuum state or an inflated state during assembly, testing, and disassembly. Therefore, it is necessary to inflate and deflate the inner cavity of the product to balance the pressure in the air chamber with the atmospheric pressure. Existing G-connectors such as figure 1 As shown, the G-type joint includes a joint housing 9. One end of the joint housing 9 is a joint threaded end 10 connected with the product housing, and the other end is a joint communication end 11 communicating with the atmosphere. The joint housing 9 is provided with a supply valve. The connecting channel 14 installed on the valve core 12 and the valve seat 13, the valve core spring 17 that pushes the valve core 12 to cut off the communication between the product cavity and the atmosphere is...
