Detailed Description

Referring to fig. 1 to 4, there is disclosed an over-current rotary sliding switch 1, which includes an over-current portion 200 and a sliding portion 300, wherein: the superflow part 200 comprises a superflow body 210 and a resetting component 220 assembled on the superflow body 210, wherein the superflow body 210 comprises a socket section 211, and the periphery of the socket section 211 is provided with an anti-drop groove 212 inwards; the sliding part 300 comprises an inner rod 310 and an outer sliding sleeve 320 movably sleeved on the inner rod 310, wherein an air outlet slot 311 is formed at one end of the inner rod 310 and sleeved on the sleeving section 211, so that the air outlet slot 311 is communicated with the superflow body 210; a release-preventing member 330 is locked to the inner rod 310 and inserted into the release-preventing groove 212, so that the sleeve section 211 of the superflow portion 200 rotates radially relative to the sliding portion 300 (as shown by the arrow in fig. 4); the other end of the inner rod 310 is provided with an air inlet groove 312 which is not directly communicated with the air outlet groove 311, the periphery of the inner rod 310 is provided with an air inlet hole 313 communicated with the air inlet groove 312, and the periphery of the inner rod 310 is provided with an air outlet hole 314 communicated with the air outlet groove 311; the inner part of the outer sliding sleeve 320 is provided with an outer expanding ring groove 321 and is located between the gas inlet hole 313 and the outer side of the gas outlet hole 314.

Referring to fig. 5 and 6, when the outer sliding sleeve 320 is slid to make the outer annular expansion slot 321 located at the outer side of the gas inlet hole 313 and the gas outlet hole 314, the outer annular expansion slot 321, the gas inlet hole 313 and the gas outlet hole 314 are communicated with each other, so that the sliding portion 300 is in an open state; thus, the gas flows to the superfluid body 210 through the gas inlet groove 312, the gas inlet side holes 313, the outer annular expansion groove 321, the gas outlet side holes 314, and the gas outlet groove 311, thereby completing the gas transportation operation. When the outer sliding sleeve 320 is slid to separate the outer annular expansion groove 321 from the outer position of the gas inlet hole 313, the outer annular expansion groove 321 is not communicated with the gas inlet hole 313, so that the sliding part 300 is in a closed state.

When the utility model is in practical use, the superflow rotary sliding switch 1 can be installed on a conveying pipeline and used as a monitoring component for outputting gas to gas equipment. The inner rod 310 is movably sleeved on the sleeve section 211 through the air outlet groove, so that the superflow part 200 can rotate in the radial direction of the sleeve section 211 relative to the inner rod 310, and after the reset component 220 is adjusted to face an upper position, the anti-release part 330 is locked and propped against the anti-release groove 212 of the inner rod 310 by a tool, so that the superflow part 200 cannot radially rotate relative to the sliding part 300, thus the superflow rotary sliding switch 1 is installed at a narrow or uneven wall surface position, and the operating mechanism of the superflow part 200 is maintained to achieve the full effect of triggering the use safety.

Further illustrating the detailed features and the mutual combination of the components of the present invention. Wherein the inner rod 310 is provided with a locking groove 315 circumferentially and inwardly, and the outer sliding sleeve 320 is movably locked with a locking member 340 and abuts against the locking groove 315, so that the sliding portion 300 is kept in a closed state. The upper locking member 340 is movably locked on the outer sliding sleeve, so that the outer sliding sleeve 320 can be locked by a tool or manually when being operated, the tail end of the locking member 340 is abutted against the locking groove 315, the position of the outer sliding sleeve 320 can be temporarily fixed, and the outer annular expansion groove 321 of the outer sliding sleeve 320 is separated from the outer side position of the gas inlet side hole 313, so that the outer annular expansion groove 321 cannot be communicated with the gas inlet side hole 313, and therefore, gas cannot pass through the position of the outer annular expansion groove 321, and the delivery of the gas is manually closed when the gas is applied to a pipeline.

In the superflow rotary sliding switch 1 of the present invention, a sealing groove 213 is circumferentially disposed on the outer peripheral side of the socket section 211 of the superflow body 210, and the sealing groove 213 is sleeved with a sealing washer 214 and is clamped against the groove wall of the air outlet groove 311 of the inner rod 310. In this embodiment, two closely-connected slots 213 are arranged at intervals, and closely-connected gaskets 214 are sleeved on the closely-connected slots 213, so that when the air outlet slot 311 of the inner rod 310 is sleeved on the sleeved section 211, the slot wall surface of the air outlet slot 311 compresses the closely-connected gaskets 214, thereby achieving a double-layer sealing effect.

In the superflow rotary sliding switch 1 of the present invention, the inner rod 310 is annularly provided with a spacing groove 316 and is located between the gas inlet hole 313 and the gas outlet hole 314, and the spacing groove 316 is sleeved with a spacing washer 317 to be clamped against the inner wall of the outer sliding sleeve. Particularly, when the outer sliding sleeve 320 slides towards the direction of the return assembly 220, although the outer expanding ring groove 321 of the outer sliding sleeve 320 is separated from the position outside the gas inlet hole 313, the inner wall surface of the outer sliding sleeve 320 compresses the spacer 317 to prevent the gas from flowing from the gas inlet hole 313 towards the gas outlet hole 314, so that the sealing effect between the inner rod 310 and the outer sliding sleeve 320 can be formed at the position to block the flow of the gas.

In the superflow rotary sliding switch 1 of the present invention, an outer ring groove 318 is circumferentially disposed around the inner rod 310 and located near the gas inlet hole 313, and the outer ring groove 318 is sleeved with an outer washer 319 and clamped against the inner wall of the outer sliding sleeve 320. When the outer ring groove 318 beside the gas inlet hole 313 is used for sleeving the outer gasket 319, the outer sliding sleeve 320 normally compresses the outer gasket 319 to deform, so as to prevent the gas from flowing to the outside from the gas inlet hole 313, thereby blocking the gas from leaking to the outside between the inner rod 310 and the outer sliding sleeve 320, and achieving a good sealing effect.

Referring to fig. 7 and 8, the operation of the superflow portion 200 of the present invention is shown, wherein the superflow portion 200 includes a locking body 230 movable within the superflow body 210; when the sliding part 300 is in the open state and the locking body 230 closes the super flow body 210, the super flow part 200 is in the locked state; when the resetting component 220 is further manipulated to drive the locking body 230 to displace without closing the super flow body 210, the super flow portion 200 is in an unlocked state. When the gas flows through the over-flow rotary sliding switch 1 and the gas is at a normal flow rate, the blocking body 230 does not close the internal passage of the over-flow body 210, and when the flow rate is abnormal or drastically changed, the gas pushes the blocking body 230 to close the internal passage of the over-flow body 210, so that the over-flow portion 200 is in a blocked state to block the gas from passing through the over-flow portion 200. When the flow rate is abnormal, the resetting component 220 can be manually operated, the locking body 230 is driven by the resetting component 220 to displace to separate from the internal channel of the closed superflow body 210, at the moment, the superflow part 200 returns to a general unlocking state, the superflow rotary sliding switch 1 can be restored to the use state, and the fuel gas can normally pass through the superflow part 200.

Referring to fig. 9, the radial dimension of the anti-slip member 330 is smaller than the groove width dimension of the anti-slip groove 212, so that when the inner rod 310 axially displaces relative to the super-flow portion 200, the anti-slip member 330 is movably limited between the groove walls of the anti-slip groove 212, and thus when the super-flow rotary sliding switch 1 of the present invention is applied to a conveying pipeline, the axial length adjustment of the sliding portion 300 relative to the super-flow portion 210 is provided, so as to change the overall axial length extension or contraction of the super-flow rotary sliding switch 1 (as shown by the hollow arrow in fig. 9), and the elastic adjustment range can be adjusted under the configuration tolerance of the conveying pipeline.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
