And patterns for increasing the friction coefficient are arranged on one side of the pressing plate in an extrusion sealing mode.

The decorative pattern is an anti-slip groove.

The rotary handles are two.

Compared with the prior art, the utility model discloses following beneficial effect has:

1) the U-shaped groove is supported by the filling mode, so that the clamping problem of the sealing strip is solved by only one clamp, and the problem of poor installation effect caused by insufficient synchronism when two clamps are used is solved.

2) The filling blocks can be detachably connected, and can be replaced, so that the filling block is suitable for U-shaped sealing strips of different specifications.

3) The problem that clamping-force is not enough can be solved to the antiskid groove, reduces the damage of anchor clamps to the sealing strip.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the use of the clamp;

wherein: 1. the device comprises a bottom plate, 2, a filling block, 3, a pressing plate, 4, a supporting plate, 5, a pressing plate guide post, 6, a spring, 7, a rotating handle, 8, a sealing strip, 9 and a nut.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

A subway train door weather strip installation jig, as shown in fig. 1, comprising:

a base plate 1;

the filling block 2 is arranged on the bottom plate 1, fixed with the bottom plate 1 and used for filling the sealing strip into the U-shaped groove;

and the two clamping heads are respectively arranged on the bottom plate 1 and positioned at two sides of the filling block 2 and used for clamping the sealing strip from two directions.

The filling block 2 and the bottom plate 1 are detachably connected through screws, patterns for increasing friction coefficients are arranged on the surface of the filling block 2, and the patterns are anti-skidding grooves in the embodiment. The two ends of the filling block 2 are provided with guide blocks, and the section area of each guide block facing outwards from the position close to the center of the filling block 2 is gradually reduced.

The chuck includes clamp plate 3, backup pad 4, clamp plate guide post 5, spring 6 and rotatory handle 7, backup pad 4 is installed on bottom plate 1 and is fixed with bottom plate 1, clamp plate guide post 5 is equipped with a plurality ofly altogether, and the one end of each clamp plate guide post 5 is fixed in on clamp plate 3, the other end passes backup pad 4 and is equipped with nut 9, 6 covers of spring are located on clamp plate guide post 5, and both ends are supported by backup pad 4 and nut 9 respectively, rotatory handle 7 is worn to penetrate in backup pad 4 through the screw thread and is close to extrusion clamp plate 3 when the forward rotation so that clamp plate 3 removes to the sealing strip direction. The number of the rotating handles 7 is two. One side of the pressing plate 3 which is extruded and sealed is provided with a pattern for increasing the friction coefficient, and the pattern is an anti-skid groove in the embodiment.

Put sealing strip 8 on filling block 2, knob handle 7 and backup pad 4 are threaded connection, and through four knob handles 7 of rotation, the tip of knob handle 7 produces pressure and acts on clamp plate 3, and clamp plate 3 extrudes sealing strip 8, and clamp plate 3 and 2 surface openings of filling block have anti-skidding groove increase frictional force, and the installation of sealing strip is accomplished in the removal of anchor clamps centre gripping sealing strip 8.
