[0026] The utility model makes further specific description in combination with the drawings. A kind of installation structure of door guide rail buffer, it includes buffer body 1 and guide rail 2, guide rail 2 is provided with lower opening 21, the width of lower opening 21 is less than the width of buffer body 1, buffer body 1 is inserted from the end surface of guide rail 2 and is installed into guide rail 2;

[0027] The both sides end surface of the described buffer body 1 is provided with elastic boss 3, after buffer body 1 is installed in guide rail 2 interior, elastic boss 3 is connected and pressed on the inner side wall of guide rail 2;

[0028] The described buffer body 1 is also provided with locking hole 5, locking nut 6 is connected in locking hole 5, locking screw 7 is screw-connected in the locking nut 6 in rotation, and rotating locking screw 7 makes the top of locking screw 7 press on the inner wall of guide rail 2, and the position of buffer in guide rail 2 is locked.

[0029] The described elastic boss 3 is circular arc protruding arrangement, and elastic boss 3 is symmetrically arranged on the both sides of buffer body 1 left and right and front and back.

[0030] The inside of the described elastic boss 3 is hollowly provided with deformation groove 4.

[0031] The described deformation groove 4 is arranged through the upper and lower end surfaces of elastic boss 3.

[0032] The described locking hole 5 is through hole through the upper and lower end surfaces of buffer body 1.

[0033] The bottom of the described locking hole 5 is provided with stepped hole, and the stepped hole is hexagonal hole, and the described locking nut 6 is embedded in the stepped hole.

[0034] The bottom of the described locking screw 7 is recessedly provided with internal hexagonal hole 71, and internal hexagonal spanner is used to drive its rotation.

[0035] The described buffer body 1 and elastic boss 3 are integrally injection molded by plastic material.

[0036] Working principle: unlike the traditional guide rail, the lower end of the guide rail of the door is provided with a lower opening, the width of the lower opening is smaller than the width of the buffer body, when the buffer body is installed, the buffer body is inserted into the guide rail from the port of the guide rail, therefore, the buffer can freely slide in the guide rail, thereby facilitating the adjustment of the installation position. Compared with the traditional suspension connection of the buffer, the installation operation is simplified, the user does not need to use both hands to cooperate with the installation, so that the installation process is more efficient and convenient.

[0037] In order to facilitate the buffer to quickly reach the best installation position, elastic bosses are arranged on the two side end faces of the buffer body in the case, the elastic bosses can increase the friction between the buffer and the guide rail. When the user closes the door, the trigger on the door can push the buffer to the best position, and the preliminary positioning function of the elastic boss is used to fix the buffer. When the user opens the door, the force direction of the trigger is opposite, so that the buffer is not pushed when the door is opened, so that the user can fix the best use position of the buffer by locking it.

[0038] Specifically: after the position of the buffer body is adjusted, the locking hole on the buffer body is used, the locking screw and the locking nut are rotatably installed, the locking screw is rotated, the top of the locking screw is stretched upwards and abuts against the inner wall of the guide rail, thereby locking the position of the buffer in the guide rail. The bottom of the locking screw is provided with an internal hexagonal hole, the user only needs to use the internal hexagonal wrench to rotate the locking screw through the internal hexagonal hole, so that the quick, stable and firm connection and fixation can be realized, the connection strength of the buffer and the guide rail is ensured, the loosening of the buffer caused by vibration or impact force during long-term use is effectively prevented, and the long-term stable use of the buffer is ensured.

[0039] Compared with the traditional technology, the elastic bosses at the head and tail of the buffer in the case can play the role of expansion positioning, and the positioning can be locked by using the locking screw, the two-end fixed mode can effectively prevent the buffer from shaking during later use. In addition, due to the positioning of the elastic boss, the size tolerance of the buffer body and the guide rail can be larger, and the self-adaptive space is larger, so that the middle section of the buffer is not too tight, thereby affecting the smoothness of the oil cylinder spring during work, so the buffer can be widely used.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above examples, the above examples and descriptions in the specification are only to illustrate the principle of the utility model, various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model.
