The plug positioning block 111 is adapted to the idle C-shaped chute 500, so that quick plug installation and extraction and disassembly with the idle C-shaped chute 500 can be realized, the structure of the abutting positioning part 112 is not limited to a plate body, a block body or other special-shaped structures, after the plug positioning block 111 is inserted into the idle C-shaped chute 500, the plug positioning block 111 at least can realize accurate positioning or approximate positioning of the mounting piece 100 in the width direction (the extending direction and the thickness direction of the non-mounting piece 100) of the mounting piece 100 (because the sealing frame mounting bolt 700 slides in the bolt chute 600), the positioning requirement on the mounting piece 100 in the width direction of the mounting piece 100 is not high, and meanwhile, the positioning in the thickness direction of the mounting piece 100 can be realized by abutting the mounting piece 100 with the idle C-shaped chute 500 or by plugging the plug positioning block 111 with the idle C-shaped chute 500. The abutment positioning portion 112 abuts against the end of the idle C-shaped chute 500 to restrict and position the mount 100 in the third direction (the extending direction of the mount 100, and generally the longitudinal direction of the mount 100).
The plug positioning block 111 and the abutment positioning portion 112 are respectively connected to the mounting member 100, and it should be noted that the plug positioning block 111 and the abutment positioning portion 112 may be directly connected to the mounting member 100 or indirectly connected to the mounting member 100, for example, the abutment positioning portion 112 may be disposed on the plug positioning block 111, and the abutment positioning portion 112 is indirectly connected to the mounting member 100 via the plug positioning block 111.
The above structure can simply and conveniently realize the rapid positioning and mounting operation of the mounting member 100 and the idle C-shaped chute 500 at low cost.
Referring to fig. 1 to 4, as a specific embodiment of the sliding plug door sealing frame mounting and positioning device provided by the present invention, the mounting member 100 has a strip-shaped structure, or a strip-shaped plate structure, and because the idle C-shaped chute 500 and the bolt chute 600 are generally longer, the mounting member 100 is designed to have a lighter strip-shaped structure for a single person to operate.
The plugging positioning block 111 is located on one side surface of the strip structure in the thickness direction, and the abutting positioning portion 112 includes two block structures protruding from two sides of the plugging positioning block 111 in the width direction of the strip structure. When the mounting member 100 is mounted, the insertion positioning block 111 is inserted into the idle C-shaped chute 500, and then the abutment positioning portion 112 abuts against the top end of the idle C-shaped chute 500 to position the mounting member 100 in the longitudinal direction of the mounting member 100.
As a specific embodiment of the sliding plug door sealing frame installation positioning device provided by the invention, as the installation piece 100 with a strip-shaped structure, one side surface in the thickness direction is provided with a special-shaped surface matched with the sealing frame, and the special-shaped surface may be a combination of a part of plane and a part of cambered surface depending on the appearance structure of the sealing frame.

When positioning the sealing frame mounting bolt 700, the sealing frame mounting bolt 700 is slid in the bolt chute 600 to a position corresponding to the positioning slot 120, then the bolt positioning member 200 is inserted in the positioning slot 120, the (bolt positioning notch 211 of the) bolt positioning member 200 passes through the positioning slot 120 and then extends to the upper side or the front side of the bolt chute 600, and the positioning of the sealing frame mounting bolt 700 in the extending direction of the bolt chute 600 is realized by using the bolt positioning notch 211.
Generally, the positioning slots 120 are in one-to-one correspondence with the bolt positioners 200, and one positioning slot 120 is used for positioning one bolt positioner 200.
Referring to fig. 2, 4, 7 and 8, as a specific embodiment of the sliding plug door sealing frame mounting and positioning device provided by the present invention, the bolt positioning member 200 includes a plug board 210 inserted into the positioning slot 120 and a positioning board 220 for abutting and positioning with a side surface of the mounting member 100 in a thickness direction, where the plug board 210 is vertically connected to the positioning board 220, and thus the plug board 210 and the positioning board 220 have a "T" structure. The bolt positioning notch 211 is disposed on the insert plate 210. The positioning plate 220 not only can realize positioning of the bolt positioner 200 in the width direction of the mounting member 100, but also the positioning plate 220 is arranged to facilitate the operation of inserting and extracting the bolt positioner 200 by an operator.
