Description

TECHNICAL FIELD

[0001] The utility model relates to hardware bumper accessories, specifically is a iron plastic composite guide rail bumper shell. BACKGROUND

[0002] The door is heavy and bulky, and once it starts to slide, it has inertia and a large impact force, which can collide with the door frame, reduce the service life of the door, and have certain safety risks. Therefore, the doors on the market are generally equipped with bumpers. When the door is pushed to slide to the side, the damping bumper provides a buffering reset function to maximize the buffering of the impact force, so that the door does not collide with the door frame, protecting the door from damage and prolonging its service life. However, the current bumper is made of hard rubber material, which can slow down the door, but due to the hard collision for a long time, the plastic material is prone to deformation or even breakage, resulting in damage and shortening the service life of the bumper. At the same time, due to the complex structure of the bumper, the production cost is high, the maintenance and replacement cost is also high, which is not conducive to popularization and use.

[0015] Figure 2 It is the structure assembly drawing of the protective cover and the buffer body in the utility model.

[0016] Figure 3 It is the structure schematic view of the protective cover in the utility model. DETAILED DESCRIPTION

[0017] The utility model discloses a kind of iron plastic composite guide rail buffer housings, it includes buffer body 1 and protective cover 2, protective cover 2 includes top plate 21 and the side plate 22 bent down and set on its both sides, top plate 21 and side plate 22 are enclosed to form mounting groove 23, buffer body 1 is embedded in the mounting groove 23;The buffer body 1 side is provided with limiting groove 3, and side plate 22 is embedded in the limiting groove 3;

[0018] The limiting groove 3 is provided with several reverse buckles 4, and correspondingly, several positioning grooves 24 are provided on side plate 22, after protective cover 2 and buffer body 1 are installed, reverse buckle 4 is clamped into positioning groove 24.

[0019] The positioning groove 24 is arranged through side plate 22.

[0020] The buffer body 1 is integrally injection molded by plastic material.

[0021] The protective cover 2 is integrally bent and formed from a metal plate.

[0022] The limiting groove 3 is concave and arranged on the both sides of the buffer body 1 and extends through the bottom of the side wall of the buffer body 1;After protective cover 2 and buffer body 1 are installed, protective cover 2 covers the bottom of buffer body 1 and its two layers, and is installed in a three-face cladding manner.

[0023] The mounting groove 23 and the side plate 22 are arranged in a "T" shape with the upper part being wide and the lower part being narrow.

[0024] Working principle: In order to protect the buffer body, a protective cover is arranged outside the buffer body. The protective cover comprises a top plate and side plates arranged downwardly on both sides of the top plate. The top plate and the side plates are combined to form a mounting groove, and the buffer body is embedded in the mounting groove.

[0025] When the protective cover is installed, a limiting groove is arranged on the two side walls of the buffer body to limit the mounting groove. The side plate is embedded in the limiting groove. Meanwhile, a plurality of reverse buckles are arranged on the limiting groove. After the protective cover and the buffer body are installed and connected, the reverse buckles are clamped into the positioning grooves arranged on the side plate, the position of the protective cover on the buffer body is locked, the buffer and the protective cover are tightly connected, the problem of loosening of the protective cover caused by sliding of the door is avoided, the connection strength of the protective cover is enhanced, and the connection is stable and firm.
