DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example
[0027] See Figures 1 to 3 As shown, a buffer structure for a sliding door comprises a mounting base plate 1 and a mounting cover plate 2 fixed to the top surface of the mounting base plate by screws. The mounting base plate has symmetrical edges on its top surface provided with limiting protrusions 3, and the mounting cover plate has symmetrical edges provided with limiting grooves 4. In this embodiment, both the mounting base plate and the mounting cover plate are constructed of plastic or metal. The limiting protrusions cooperate with the limiting grooves to limit the position of the two during installation, preventing displacement and ensuring smooth operation. The limiting protrusions also limit the buffer cylinder, preventing it from shaking or shifting.
[0028] During actual application, a avoidance groove 5 is provided on the side surface of one end of the mounting base; a buffer cylinder 6 is clamped and positioned between the mounting base and the mounting cover; in this embodiment, the buffer cylinder is a conventional structure of the prior art and is simply used, while the avoidance groove is mainly used for the translational buffering operation of the limiting hook structure.
[0029] In actual use, a guide frame 7 is provided at the avoidance groove. The top edge of the guide frame is fixed to the mounting cover plate by screws, and the bottom edge of the guide frame is fixed to the mounting base plate by screws. A strip-shaped buffer groove 8 is provided on the guide frame. A limiting hook structure 9 is fixed to the piston shaft of the buffer cylinder. The outer end of the limiting hook structure passes through the strip buffer groove and extends out of the outer side surface of the guide frame. The limiting hook structure can translate within the strip buffer groove. The limiting hook structure cooperates with the guide frame to not only provide guidance but also prevent the limiting hook structure from colliding with or wearing the mounting base plate and mounting cover plate, which is conducive to improving the stability of use and service life, and has strong applicability.
[0030] In actual use, the limit hook structure comprises a hook base 91 and a C-shaped hook body 92 rotatably connected to the hook base via a pin 93. During assembly, the piston shaft of the buffer cylinder is fixed to the hook base, and the C-shaped hook body extends outward from the guide frame. This structure ensures the effective translation of the hook base and also helps ensure the effective contact of the C-shaped hook body with the translation position.
[0031] In actual use, the guide frame is a C-shaped frame. Both the bottom surface of the mounting base and the top surface of the mounting cover are provided with recessed areas 10. The top edge of the C-shaped frame snaps into the recessed area of the mounting cover, and the bottom edge of the C-shaped frame snaps into the recessed area of the mounting base, secured by screws. The guide frame is a metal structure. This structure ensures an aesthetically pleasing overall appearance during assembly while also ensuring the normal sliding opening operation of the sliding door, thereby improving operational stability and reliability.
[0032] In actual use, the mounting base plate is provided with vertical strip grooves 11 on both ends of the side surface; the vertical strip grooves are provided with mounting screw holes 12. This structure can improve the installation convenience of the entire structure. It is fixed to the door frame through the mounting screw holes and can abut against the limit hook structure to provide buffering when the horizontal sliding door is pushed horizontally.
[0033] The utility model has positive effects: the structure of the utility model is reasonably set up, and it can abut and buffer the sliding door by arranging a buffer cylinder and a limiting hook structure, which is beneficial to improving the anti-finger pinching performance, and the buffer cylinder is fixed when the overall structure is assembled, thereby also ensuring the stability of the use of the overall structure. At the same time, the guide frame is matched with the limiting hook structure, and the guide frame can be used for guidance and limitation, which can prevent the limiting hook structure from damaging the installation base plate and the installation cover plate, which is beneficial to improving the stability of use and service life, and has strong applicability and good practicality.
[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.
[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
