Description

Quick-acting coupling assembly

Technical Field

The utility model belongs to the technical field of attach fitting's technique and specifically relates to a quick-operation joint subassembly is related to.

Background

The conventional various quick connectors on the market are in a threaded type and a spring ball type, but the two types of connectors have defects, and the connectors are connected by threads, so that the assembly and disassembly operations are complicated, and the quick connectors are not suitable for working occasions requiring short-time frequent assembly and disassembly; the latter has complex structure, complex processing and assembly and higher production cost; therefore, the technical problem to be solved in the field is to provide a quick connector which has a simple structure, is convenient to operate and can realize quick assembly and disassembly;

in order to solve the problems, the chinese invention with the publication number CN 106641534 a discloses a quick connector, which comprises a connector body, a clamping mechanism and a locking sleeve, wherein the clamping mechanism is fixedly connected to the outer wall of the connector body, and when the clamping jaws are in an open state, the male end type structural member can be inserted into or pulled out of the receiving hole; when the clamping jaws are in a contraction state, the outer spigot type structural part can be limited and fixed in the receiving hole; the locking sleeve can move between a use position and a non-use position, when the locking sleeve is in the non-use position, the jaws of the clamping mechanism are in an open state, and when the locking sleeve is in the use position, the jaws of the clamping mechanism are in a contraction state; compared with the traditional quick joint structure, the quick joint provided by the invention is convenient to use, does not need any tool, and can quickly complete the assembly and disassembly work of the external spigot type structural member by applying small external force to an operator, but the quick joint is still relatively complicated in structure, so that the processing and manufacturing cost is high;

in order to solve the above problems, the Chinese utility model with the publication number of CN 209370641U discloses a quick coupling, in the claim 2, "the inner hole of the lantern ring (22) is provided with at least one mounting groove (23) along the length direction of the lantern ring (22)," the outer circle of the valve rod (3) is convexly provided with a convex block (32) matched with the mounting groove (23), one end of the mounting groove (23) close to the elastic clamping jaw (21) is provided with an arc-shaped retaining groove (24) positioned at the same circular ring position, the mounting groove (23) is communicated with the retaining groove (24) ", although the projection (32) is in the retaining groove (24) through the mounting groove (23), because there is no locking mechanism, when the quick connector is turned upside down, the lug (32) can slide out of the retaining groove (24) through the mounting groove (23) as usual, so that the valve rod (3) is separated from the clamping ring (2); this is one of the defects of the chinese utility model with the publication number CN 209370641U;

chinese utility model with publication number CN 209370641U in claim 3, "the collar (22) is sleeved with a sealing ring (4), the sealing ring (4) is pressed against the end of the retainer ring (25) and the joint body (1) close to the first threaded section (11)", the sealing ring 4 is provided to "enhance the sealing performance of the quick joint" in combination with paragraph [0042] in the specification; in fact, a gap is formed between the valve rod (3) and the clamping ring (2) because the valve rod needs to slide, and if fluid leaks in the gap, the fluid can flow out of the gap, so that the arrangement of the sealing ring 4 is meaningless, which is the second defect of the Chinese utility model with the publication number of CN 209370641U;

the chinese utility model with the publication number CN 209370641U of claim 4 discloses that "one end of the inner bore of the joint body (1) away from the first thread section (11) is provided with a third thread section (13), the third thread section (13) is connected with a press ring (6) in a threaded manner, and the inner diameter of the press ring (6) is smaller than the spigot outer diameter of the male end structural tube (5). "; the invention of claim 5 includes that "one end of the press ring (6) close to the elastic claw (21) is fixedly connected with a sealing rubber gasket (7)"; in combination with paragraph [0043] in the specification, the "sealing rubber gasket 7" can play a role in sealing between the pressure ring 6 and the male end structure tube 5 to prevent fluid from flowing out of the outer side of the male end structure tube 5, and in the above arrangement, the sealing ring 4 and the sealing rubber gasket 7 play a role in double sealing for the quick coupling to improve the sealing performance of the device; the sealing of the male end structure tube (5) to the body (1) achieved in the above-described manner without a locking mechanism is not guaranteed, and the possibility of fluid leakage under high pressure is high; the third defect of the Chinese utility model with the notice number of CN 209370641U;

the chinese utility model with the publication number CN 209370641U is not improved by the above 3 drawbacks in

claims

6, 7, 8 and 9;

in summary, the chinese utility model with the publication number CN 209370641U needs to be invented again to be completed if it is a very incomplete design only according to claim 1, and has a great disadvantage if it is implemented according to claims 1 to 9.
