Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The sealing gasket mounting structure of a kind of gas meter motor valve as depicted in figs. 1 and 2, comprise sealing gasket body 1 and be sheathed on the drive nut 2 in sealing gasket body 1, the outer wall of drive nut 2 is circumferentially provided with the first annular groove 21, the outer wall of sealing gasket body 1 and be arranged with clip 3 with drive nut 2 corresponding position, specifically, in order to avoid loosening appears in clip 3 vertically, the outer wall of sealing gasket body 1 is provided with three annular groove 11 suitable with clip 3, and the inwall of clip 3 is convexly equipped with some projections 33 matched with the first annular groove 21.
During installation, first drive nut 2 is inserted in the inwall of sealing gasket body 1, then be locked in the outside of sealing gasket body 1 clip 3, due to sealing gasket body 1 for flexible material is made, make projection 33 can crush seal pad body 1 snapping in the first annular groove 21, thus it be fixing to realize drive nut 2.
In sum, compared with prior art, the utility model is by arranging clip 3, make projection 33 force in radial larger, and because projection 33 and drive nut 2 all adopt rigid material to make, thus drive nut 2 is not easily dropped, effectively ensure that the utility model installs the stability connected.
As a kind of preferred implementation of the present utility model, the inwall that clip 3 comprises the first halfround bar slice 31, the second halfround bar slice 32, first halfround bar slice 31 be fixedly connected with the first halfround bar slice 31 and the second halfround bar slice 32 is provided with some projections 33.First halfround bar slice 31 is identical with the structure of the second halfround bar slice 32, and one end of the first halfround bar slice 31 is extended fixture block 34, and the other end of the first halfround bar slice 31 is provided with the bayonet socket 35 corresponding with fixture block 34.During connection, the fixture block 34 of the first halfround bar slice 31 is inserted in the bayonet socket 35 of the second halfround bar slice 32, and is fixedly connected with the second halfround bar slice 32; The fixture block 34 of the second halfround bar slice 32 is inserted in the bayonet socket 35 of the first halfround bar slice 31, and is fixedly connected with the first halfround bar slice 31.
Coordinate by the first halfround bar slice 31 and the second halfround bar slice 32 clip 3 formed by arranging, and fixture block 34 and bayonet socket 35 are set respectively in the end of the first halfround bar slice 31 and the second semicircle, only fixture block 34 need be inserted in corresponding bayonet socket 35 during installation, and then just can realize being fastenedly connected, install comparatively convenient, fast, and stability is higher.
It is through with corresponding bayonet socket 35 that the outer wall of the first halfround bar slice 31 is circumferentially provided with the second annular groove 36, second annular groove 36, and the end of fixture block 34 is through corresponding bayonet socket 35 and be inserted in the second annular groove 36.By arranging the second annular groove 36 respectively at the outer wall of the first halfround bar slice 31 and the second halfround bar slice 32, when not only avoid installation, fixture block 34 protrudes from the outside of the first halfround bar slice 31 (or second halfround bar slice 32), make aesthetics higher, and save space for the subsequent installation of motor valve.Specifically, the fixture block 34 of the first halfround bar slice 31 is inserted in the second annular groove 36 of the second halfround bar slice 32, and in like manner, the fixture block 34 of the second halfround bar slice 32 is inserted in the second annular groove 36 of the first halfround bar slice 31.
In order to make assembling more laborsaving, being convenient to fixture block 34 and being inserted in bayonet socket 35, the second annular groove 36 is provided with the joint of bayonet socket 35 inclined-plane 361 passed for fixture block 34, and the end of fixture block 34 is provided with the arc surface 341 suitable with the outer wall of the first halfround bar slice 31.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
