DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figures 1 to 4 As shown, the utility model discloses a light rail plug valve, comprising: an upper mounting seat 1, a lower mounting seat 2, a first door plate 3, a second door plate 4, a pressing and positioning mechanism 5 and a guiding mechanism 6; the upper mounting seat 1 and the lower mounting seat 2 are on the wall of the vent, the upper mounting seat 1 is located above the lower mounting seat 2, the first door plate 3 and the second door plate 4 are installed between the upper mounting seat 1 and the lower mounting seat 2, and the first door plate 3 and the second door plate 4 are used to open and close the vent; the upper mounting seat 1 and the lower mounting seat 2 are both installed with a pressing and positioning mechanism 5, the pressing and positioning mechanism 5 is used to position the first door plate 3 and the second door plate 4, and the pressing and positioning mechanism 5 can lock the first door plate 3 and the second door plate 4 in an open or closed state; the first door plate 3 The first door panel 3 and the second door panel 4 both include: a plate body 31 and a protrusion 32, the plate body 31 is tightly attached to the vent wall, and the plate body 31 protrudes on one side away from the vent wall to form a protrusion 32, and the protrusion 32 is used to connect the plate body 31 to the guide rail 61; the guide mechanism 6 includes: a guide rail 61 and a hanging block 62, the hanging block 62 is installed on the upper mounting seat 1 or the lower mounting seat 2, the hanging block 62 hooks the guide rail 61, the side wall of the guide rail 61 is provided with a groove, the protrusion 32 is fixed in the groove, the guide rail 61 can move in the X direction relative to the hanging block 62, and the guide mechanism 6 is used to make the sliding opening and closing of the first door panel 3 and the second door smoother, and there will be no blocking of sliding, thereby achieving the effect of ventilation or closing ventilation.

[0023] The suspension block 62 is mounted on the upper mounting seat 1 or the lower mounting seat 2 through the mounting mechanism 7. The suspension block 62 is detachably mounted through the mounting mechanism 7.

[0024] The mounting mechanism 7 includes: a pad 71 and a hanging screw 72. The top of the hanging block 62 passes through the upper mounting seat 1 or the lower mounting seat 2, and the bottom of the hanging block 62 hooks the guide rail 61. The pad 71 is installed between the hanging block 62 and the upper mounting seat 1. The pad 71 is for the hanging screw 72 to pass through, and the hanging screw 72 also passes through the hanging block 62. The hanging screw 72 presses the hanging block 62 and the pad 71 onto the upper mounting seat 1 or the lower mounting seat 2. The mounting mechanism 7 is used to fix the hanging block 62 on the upper mounting seat 1 or the lower mounting seat 2, and use the hanging block 62 to make the upper mounting seat 1 or the lower mounting seat 2 slidably connected with the first door panel 3 and the second door panel 4. Since the position of the through hole for the hanging block 62 to pass through the upper mounting seat 1 or the lower mounting seat 2 is not fixed, a cushion block 71 is designed. The thickness of the cushion block 71 can be adjusted. When it is adjusted to the point where the hanging screw 72 can be screwed into the wall, the large end of the hanging screw 72 presses the top of the hanging block 62 and the cushion block 71 onto the upper mounting seat 1 or the lower mounting seat 2, thereby achieving the installation of the hanging block 62 at the same time when the upper mounting seat 1 and the lower mounting seat 2 are installed and positioned, thereby simplifying the mounting seat and improving the installation efficiency.

[0025] The mounting mechanism 7 also includes: a blocking block 73. A strip hole is opened on the hanging block 62, and the strip hole is for the hanging screw 72 to pass through. The gap between the hanging screw 72 and the inner wall of the strip hole is blocked by the blocking block 73. The blocking block 73 can limit the hanging screw 72 to prevent the hanging screw 72 from deviating in the Z direction.

[0026] Both the first door panel 3 and the second door panel 4 are provided with booster handles, so as to facilitate operators to open and close the first door panel 3 and the second door panel 4 .

[0027] The upper mounting seat 1 and the lower mounting seat 2 both include: a close-fitting plate 11, an intermediate plate 12 and a baffle 13. The close-fitting plate 11 is close-fitting to the vent wall, and the bottom end of the close-fitting plate 11 is fixed to the baffle 13 through the intermediate plate 12. The baffle 13 is parallel to the close-fitting plate 11 and is blocked outside the guide rail 61.

[0028] The pressing and positioning mechanism 5 includes: a mounting tube 51 and a positioning bolt 52. The mounting tube 51 is mounted on the upper mounting seat 1 or the lower mounting seat 2. The mounting tube 51 is threadedly connected with the positioning bolt 52. The positioning bolt 52 can pass through the baffle 13 and be pressed against the first door panel 3 or the second door panel 4. When the first door panel 3 and the second door panel 4 are opened or closed, the positioning bolt 52 is twisted and screwed into the mounting tube 51 until the end of the positioning bolt 52 is pressed against the plate body 31 of the first door panel 3 and the second door panel 4, so that the first door panel 3 and the second door panel 4 are kept in an open or closed state.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
