DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model.

[0021] The utility model provides technical scheme: as Figure 1 AndFigure 2 As shown in the embodiment, a boltless mute comb plate expansion joint includes a fixed comb plate 1 and a movable comb plate 2. The tooth grooves of the fixed comb plate 1 and the tooth grooves of the movable comb plate 2 are staggered. The bottom of the fixed comb plate 1 is fixedly connected with a first steel plate 4. The bottom of the movable comb plate 2 is provided with a second steel plate 5. A connecting plate 3 is installed between the first steel plate 4 and the second steel plate 5. The top of the connecting plate 3 is fixedly connected with a filling block 6.

[0022] The filling block 6 is arranged in the tooth groove gap between the fixed comb plate 1 and the movable comb plate 2. When the movable comb plate 2 deforms, the filling block 6 can be extruded to achieve a damping and buffering effect without generating a large noise to achieve the purpose of mute.

[0023] The connecting plate 3 and the filling block 6 are both made of rubber material. Due to the material properties of the connecting plate 3 and the filling block 6, they can quickly recover after being extruded by the movable comb plate 2 and have good elasticity, wear resistance, aging resistance and waterproofness, and can be used for a long time.

[0024] The bottom of the first steel plate 4 and the bottom of the second steel plate 5 are both fixedly connected with an anchoring plate 7.
