Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to an impact-resistant sliding door. Background Technology
[0002] Traditional sliding doors mainly consist of a fixed door frame and a movable door panel. The movable door panel is slidably connected to the door frame guide rail via a bottom pulley assembly. Users apply horizontal pushing force to drive the movable door panel horizontally along the guide rail, and the relative displacement between the door panel and the door frame achieves opening or closing. The door frame and the movable door panel typically employ a mechanical structure using metal guide rails and rollers to ensure the stability of the door panel's movement and meet load-bearing requirements.
[0003] In practical use, it has been found that when the sliding door panel moves to its fully closed or fully open extreme position, a rigid collision occurs between the edge of the door panel and the door frame due to the lack of an effective buffering mechanism. Experimental tests show that the peak impact force generated at the moment of impact can reach 50-80N. Long-term exposure can lead to stress concentration at the contact surface between the door frame and the door panel, resulting in deformation of the sliding door. More seriously, the abnormal impact load borne by the sliding connection components during the final collision will accelerate wear, leading to increased running resistance, track misalignment, and other malfunctions, reducing the overall stability of the sliding door. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an impact-resistant sliding door that is less prone to deformation, reduces wear on the sliding connection parts of the sliding door, and improves the stability of the sliding door.
[0005] To solve the above-mentioned technical problems, the present invention provides an impact-resistant sliding door, including a guide rail, a damping buffer, a movable door, and a buffer block installed on the movable door. The guide rail is provided with a mounting groove extending to the left and right. The two damping buffers are arranged back to back and are installed at the left and right ends of the mounting groove. The buffer block is used to extend into the mounting groove and abut against the output end of the damping buffer.
[0006] As an improvement to the above solution, the damping buffer includes a connecting strip installed in the mounting groove and a hydraulic rod installed in the connecting strip, and the buffer stop is used to abut against the output end of the hydraulic rod.

The buffer block is used to slide with the guide groove and abut against the hydraulic rod output end in the buffer groove.
[0008] As an improvement to the above solution, the openings of the mounting groove, the buffer groove, and the guide slot are all positioned facing forward.
[0009] As an improvement to the above solution, the impact-resistant sliding door of this utility model also includes a movable seat. The guide rail is provided with a guide groove in front of the mounting groove. The buffer block is fixed on the rear side of the movable seat. A plurality of rollers are rotatably connected to the rear side of the movable seat and are spaced apart on the left and right. The rollers are placed in the guide groove and abut against the guide groove to drive the movable door to move left and right.
[0010] As an improvement to the above solution, the impact-resistant sliding door of this utility model also includes an eccentric component. The movable door is provided with a first mounting through hole. The eccentric component includes a locking bolt, a mounting platform with an outer diameter larger than the first mounting through hole, and a mounting column disposed on the rear side of the mounting platform and offset from the axis of the mounting platform. The front side of the eccentric component is provided with a second mounting through hole, the axis of the second mounting through hole coincides with the axis of the mounting platform. The mounting column is used to extend into the first mounting through hole and rotatably connect with the first mounting through hole. The locking bolt is used to pass through the second mounting through hole and threadedly connect with the movable seat.
[0011] As an improvement to the above solution, the impact-resistant sliding door of this utility model also includes a decorative cover for installation on the front side of the movable door, and the rear side of the decorative cover is provided with a locking cavity for engaging with the mounting platform.

[0013] Implementing this utility model has the following beneficial effects:
[0014] The impact-resistant sliding door of this utility model uses guide rails, damping buffers, movable doors, buffer blocks, and mounting grooves to work together to reduce the moving speed of the buffer blocks and movable doors before the movable doors are fully opened or closed, preventing rigid collisions of the movable doors or greatly reducing the force of rigid collisions of the movable doors, making the movable doors less prone to deformation, reducing the wear of the sliding connection parts of the movable doors, and improving the stability of the sliding door.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.
[0028] like Figures 1 to 4 As shown in the figure, an impact-resistant sliding door according to an embodiment of this utility model includes a guide rail 100, a damping buffer 200, a movable door 300, and a buffer block 400 installed on the movable door 300. In practice, the movable door 300 can be a door frame installed on a building structure and a door panel movably connected to the left and right sides of the door frame. The buffer block 400 is installed on the door panel, and the buffer block 400 can be installed on the movable door 300 by means of adhesive, snap-fit, threaded connection, or integral molding, so that the buffer block 400 and the movable door 300 move horizontally together.
[0029] The guide rail 100 is provided with a mounting groove 110 extending to the left and right. Two damping buffers 200 are arranged back to back and are installed at the left and right ends of the mounting groove 110 respectively. The buffer block 400 is used to extend into the mounting groove 110 and abut against the output end of the damping buffer 200. In fact, the damping buffer 200 can be one of mechanical, pneumatic and hydraulic types. The medium of these types can be compressed and the impact contact time is extended to achieve buffering. Before installing the damping buffer 200, the installation position of the two damping buffers 200 should be adjusted so that when the movable door 300 closes, the buffer block 400 first contacts the damping buffer 200 at one end of the guide rail 100, and when the movable door 300 closes, the buffer block 400 first contacts the damping buffer 200 at the other end of the guide rail 100, so as to avoid rigid collision when the movable door 300 opens and closes.
[0030] The specific working principle of the impact-resistant sliding door of this utility model embodiment is as follows: When the movable door 300 opens or closes, it drives the buffer block 400 to move left and right and move within the mounting groove 110 of the buffer block 400; when the movable door 300 is about to be fully opened or fully closed, the buffer block 400 first contacts and abuts against the output end of the damping buffer 200, and the damping buffer 200 reduces the moving speed of the buffer block 400 and the movable door 300, preventing the movable door 300 from having a rigid collision or greatly reducing the force of the rigid collision of the movable door 300.
[0031] The impact-resistant sliding door of this utility model embodiment uses the guide rail 100, damping buffer 200, movable door 300, buffer block 400 and mounting groove 110 to cooperate with each other. It can reduce the moving speed of buffer block 400 and movable door 300 before the movable door 300 is fully opened or fully closed, prevent the movable door 300 from having a rigid collision or greatly reduce the force of the rigid collision of the movable door 300, make the movable door 300 less likely to deform, reduce the wear of the sliding connection parts of the movable door 300, and improve the stability of the sliding door.
[0032] Specifically, the damping buffer 200 preferably includes a connecting strip 210 installed in the mounting groove 110 and a hydraulic rod 220 installed in the connecting strip 210. The buffer block 400 is used to abut against the output end of the hydraulic rod 220. In fact, by using the hydraulic rod 220 for buffering, when the buffer block 400 contacts the output end of the hydraulic rod 220, the compression deformation of the hydraulic rod 220 is better than that of mechanical and pneumatic types, further ensuring the stability of the impact-resistant sliding door. Furthermore, the connecting strip 210 can be used to fix the hydraulic rod 220 in the mounting groove 110 by welding, bonding, or threaded connection, thus protecting the base of the hydraulic rod 220.
[0033] Preferably, the outer portion of the connecting strip 210 is provided with a buffer groove 211 for the hydraulic cylinder output end to extend out and extends left and right, and the inner portion of the connecting strip 210 is provided with a guide groove 212 extending left and right and communicating with the buffer. The buffer stop 400 is used to slide with the guide groove 212 and abut against the output end of the hydraulic rod 220 in the buffer groove 211. In practice, the left damping buffer 200 has a buffer groove 211 on the left and a guide groove 212 on the right, and the right damping buffer 200 has a buffer groove 211 on the right and a guide groove 212 on the left. In actual application, the buffer stop 400 first enters the guide groove 212 for guidance and then enters the buffer groove 211 to abut against the output end of the hydraulic rod 220. The combined action of the guide groove 212 and the buffer groove 211 prevents the buffer stop 400 from collapsing with the outer side of the connecting strip 210 and ensures that the buffer stop 400 abuts against the output end of the hydraulic rod 220. More specifically, the openings of the mounting groove 110, the buffer groove 211, and the guide slot 212 are preferably arranged facing forward. In fact, the movable door 300 is arranged on the front side of the guide rail 100 to ensure that the buffer block 400 can extend from back to front into the mounting groove 110, the buffer groove 211, and the guide slot 212.
[0034] It should be noted that the impact-resistant sliding door of this utility model preferably also includes a movable base 500. The guide rail 100 is provided with a guide groove 120 in front of the mounting groove 110. The buffer block 400 is fixedly mounted on the rear side of the movable base 500. A plurality of rollers 510 spaced apart on the left and right sides are rotatably connected to the rear side of the movable base 500. The rollers 510 are placed in the guide groove 120 and abut against the guide groove 120 to drive the movable door 300 to move left and right. Through the movable base 500, rollers 510 and guide groove 120, the movable door 300 is slidably connected to the guide rail 100. The multiple rollers 510 act in the guide groove 120 to prevent the movable door 300 from swinging during movement and to prevent the buffer block 400 from swinging up and down and hitting the guide rail 100 during movement, thus ensuring the stability of the impact-resistant sliding door of this utility model.
[0035] It is worth mentioning that bathroom floors often have an angle due to water accumulation, resulting in a degree of inclination. This makes it easy for the lower edge of the sliding door 300 to hit the ground when moving left or right. To address this, the impact-resistant sliding door of this invention preferably includes an eccentric component 600. The sliding door 300 has a first mounting through hole 310. The eccentric component 600 includes a locking bolt 610, a mounting platform 620 with an outer diameter larger than the first mounting through hole 310, and a mounting post 630 located on the rear side of the mounting platform 620 and offset from the axis of the mounting platform 620. The front side of the eccentric component 600 has a second mounting through hole 640, the axis of which coincides with the axis of the mounting platform 620. The mounting post 630 extends into the first mounting through hole 310 and is rotatably connected to it. The locking bolt 610 passes through the second mounting through hole 640 and is threadedly connected to the moving seat 500. In practice, the axis of the mounting column 630 is offset from the axis of the mounting platform 620, and the axis of the second mounting through hole 640 is offset from the axis of the first mounting through hole 310. This results in the outer side of the mounting axis being thicker on one side and thinner on the other side relative to the axis of the mounting platform 620. When the mounting platform 620 is rotated by an external force, the interaction of the guide groove 120, multiple rollers 510, and the movable seat 500 drives the movable door 300 to move up and down, thereby changing the vertical position of the movable door 300 within a certain range and adjusting the distance between the lower edge of the movable door 300 and the ground to prevent the lower edge of the movable door 300 from colliding with the ground. Furthermore, through the threaded connection between the locking bolt 610 and the movable seat 500, the mounting platform 620 and the movable seat 500 generate a clamping force on the movable door 300, preventing the mounting platform 620 from rotating and ensuring the stability of the impact-resistant sliding door.
[0036] Furthermore, the impact-resistant sliding door of this utility model preferably also includes a decorative cover 700 for installation on the front side of the sliding door 300. The decorative cover 700 has a locking cavity 710 on its rear side for engaging with the mounting platform 620. In practice, the decorative cover 700 can be installed on the front side of the sliding door 300 by adhesive or threaded connection to prevent water from splashing onto the mounting platform 620 and from accidentally touching the mounting platform 620 during bathroom use.
[0037] In addition, the rear side of the movable seat 500 is preferably rotatably connected to two rollers 510 spaced apart from left to right, and the buffer block 400 is disposed between the two rollers 510. When the buffer block 400 abuts against the output end of the hydraulic rod 220, the interaction is transmitted more evenly to the two rollers 510, thus optimizing the layout of the rollers 510 and the buffer block 400.
[0038] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
