Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in FIGS. 1 to 6, the preferred embodiment of the present invention is shown. The joint for detecting the gas interface of the gas stove in the embodiment comprises a detection joint 1, wherein the detection joint 1 comprises a head part 11 for connecting the gas interface 2 and a tail part 12 for connecting the gas supply pipe 3, the head part 11 is of a double-ring-wall structure and comprises an inner ring wall 111 and an outer ring wall 112 which are arranged from inside to outside at intervals, the inner ring wall 111 surrounds a central cavity 1111 for the gas of the gas supply pipe 3 to flow into the gas interface 2, the outer ring wall 112 is used for being sleeved outside the gas interface 2, and the inner ring wall 111 is used for extending into the gas interface 2. The lock catch structure 4 that the afterbody 12 and the air supply pipe 3 of detecting joint 1 are connected, wherein, this lock catch structure 4 is including:

an elastic ring 41, the elastic ring 41 having a fixed part 411 and a free end 412 wound from the fixed part 411, the fixed part 411 and the free end 412 forming an opening 413 for the tail part 12 of the test connector 1 to pass through, and the free end 412 always having a tendency to expand the opening 413; and a fastening member 42 disposed on the fixing portion 411 and the free end 412, wherein the fastening member 42 facilitates the tightening of the opening 413. In order to realize the tightening of the opening 413 driven by the fastening member 42, wherein the fastening member 42 includes a first lug 421 and a second lug 422 respectively disposed on the fixing portion 411 and the free end 412, an adjusting head 423 for changing the relative distance between the first lug 421 and the second lug 422 is connected to the first lug 421 and the second lug 422, the adjusting head 423 is an adjusting handle, the adjusting handle includes a handle tail portion 4231 and a handle head portion 4232, in order to change the relative distance between the first lug 421 and the second lug 422, the surface of the handle tail portion 4231 is threaded, and correspondingly, the first lug 421 and the second lug 422 respectively have threaded holes for the handle tail portion 4231 of the adjusting handle to be in threaded connection.
