Description

TECHNICAL FIELD

[0001] The utility model relates to a hardware fitting, concretely is a kind of door buffer and guide rail mounting structure. BACKGROUND

[0002] Slip door system is widely used in modern architecture, such as sliding door, wardrobe door and the like, which realizes the stable sliding of door leaf through guide rail. As one of the key components of slip door system, buffer plays a role in reducing impact force during the closing of door leaf, so as to ensure that the door leaf can be closed smoothly and quietly, avoiding noise or damage caused by too fast closing. However, the existing installation method of slip door buffer has some significant shortcomings, which affects the installation efficiency, use flexibility and long-term stability of the system.

[0003] For example, in the existing slip door buffer system, the buffer is usually installed into the guide rail through the lower opening of the guide rail. This installation method requires the operator to first insert the buffer into the guide rail and position it to the predetermined position during the installation process, and then fix it. Because the space inside the guide rail is narrow, and the buffer needs to be aligned with the specific structure of the guide rail, the operator often needs to operate with both hands: one hand holds the buffer to maintain its position, and the other hand uses a tool such as a screwdriver to tighten. This two-handed operation significantly increases the complexity of installation, especially when installing in a small space or at a high place, the operation difficulty is further increased, which reduces the installation efficiency. In addition, two-handed operation may cause the buffer to be positioned inaccurately due to the operator's lack of experience or improper use of tools, which affects the subsequent function realization.

[0004] More importantly, the existing buffer is usually directly fixed in the guide rail by screws. Once the screw is tightened, the position of the buffer is completely locked and cannot be adjusted subsequently. However, in actual use, the use requirements of the slip door system may change due to the weight of the door leaf, the closing speed or the change of environmental conditions such as temperature and humidity. For example, when the door leaf is heavy, it may be necessary to adjust the position of the buffer to enhance the buffering effect; or when the closing speed is fast, it is necessary to fine-tune the installation position of the buffer to optimize the shock absorption performance. The existing fixed installation method cannot meet the demand of flexible adjustment, which limits the adaptability and practicality of the slip door system.

[0005] In addition, the direct use of screws in the prior art also has potential stability problems. Since the buffer bears a certain impact force during the repeated movement of the door leaf, if the screw loosens due to long-term use, or if the tightening force is insufficient during initial installation, the buffer may shift or even fall off inside the guide rail. This situation not only causes the failure of the buffering function, but also threatens the overall safety and reliability of the slip door system, so it is necessary to make further improvements. SUMMARY

[0006] The utility model discloses a kind of door buffer and guide rail mounting structures, which can effectively improve the convenience of installation, flexibility of adjustment and stability of use, thereby better meet the practical needs of modern door system.

[0007] The utility model discloses the following mode is realized: a kind of door buffer and guide rail mounting structure, it includes guide rail and the buffer installed in it, wherein:

[0008] The guide rail includes the first side in n-shaped distribution, and the second side and the third side are arranged on its two sides, the first side, the second side and the third side are enclosed to form the accommodating cavity, and the buffer is installed in the accommodating cavity.

[0009] The second side extends to the fourth side in the direction of the third side.

[0010] The third side extends to the fifth side in the direction of the second side.

[0011] The fourth side and the fifth side are hollowed out to form a guide groove, and the trigger block on the buffer slides in the guide groove.

[0012] The buffer is embeddedly installed in the accommodating cavity, and the buffer is provided with locking bolts at both ends, which are pressed on the bottom of the accommodating cavity to fix the buffer in the accommodating cavity.

[0013] Further, the buffer is provided with mounting holes on the upper and lower end faces of the body, the mounting holes are fixedly installed with nuts, and the locking bolts are screwed with the nuts.

[0014] Further, the locking bolt is an internal hexagonal bolt.

[0015] Further, the mounting holes are located within the orthographic projection range of the guide groove.

[0016] Further, the outer side surfaces of the second side and the third side are provided with anti-skid strips.

[0017] Further, the fourth side and the fifth side extend to limiting baffle plates outside.

[0018] Further, the guide rail is made of aluminum alloy profile.

[0019] The utility model has the advantages of simple structure, low manufacturing cost and improved market competitiveness.

[0020] 2、The utility model discloses a buffer is embedded in the containing cavity of guide rail, and adopts the fixed mode of the screw joint of locking bolt and the nut in the buffer, and the installation process is optimized. Compared with the complex operation of buffer in prior art needing to be inserted through the lower opening of guide rail and positioned by both hands, the design of the utility model allows the operator to place the buffer in the containing cavity first, and then fix it through the locking bolt, without the need for simultaneous operation by both hands. This one-handed installation method significantly reduces the installation difficulty and time cost, and shows higher convenience, especially when working in a small space or at a high place.

[0021] 3、In the utility model, the buffer is fixed through the screw joint of locking bolt and nut, and the locking bolt is pressed on the bottom of guide rail. Compared with the defect of position lock caused by direct screw fixation in prior art, the design allows the user to loosen the locking bolt when needed, and then retighten after fine-tuning the position of the buffer along the containing cavity. This flexible adjustment function can adapt to the needs of different use scenarios, such as optimizing the buffering effect according to the weight of door leaf or the change of closing speed, thereby improving the practicability and adaptability of the door system.

[0022] 4、The screw joint fixation mode of locking bolt and nut ensures the firm installation of the buffer in the containing cavity. Compared with direct screw fixation in prior art, the utility model increases the fastening force and stability of the connection through the cooperation of bolt and nut, significantly reducing the risk of buffer displacement or falling due to loose or improper installation of screw. This design improves the reliability of the door system in long-term use, especially under the impact force generated by repeated movement of the door leaf, which can still maintain a stable working state.

[0023] 5、The containing cavity formed by the first edge and the second edge and the third edge on both sides of the guide rail provides a stable installation space for the buffer. At the same time, the fourth edge and the fifth edge extending out of the second edge and the third edge respectively are hollowed to form a guide groove, providing a trigger sliding on the buffer. This structural design not only ensures the fixation of the buffer, but also ensures the normal movement function of the trigger block, providing higher integration and functionality compared with the simple guide rail opening design in prior art.

[0027] The utility model discloses a kind of door buffer and guide rail mounting structure, it includes guide rail and the buffer 8 installed in it, wherein:

[0028] The guide rail includes the first edge 1 of n-shaped distribution, and the second edge 2 and the third edge 3 arranged on its two sides, the first edge 1, the second edge 2 and the third edge 3 are enclosed to form the accommodating cavity 6, and the buffer 8 is installed in the accommodating cavity 6.

[0029] The second edge 2 extends to the fourth edge 4 in the direction of the third edge 3.

[0030] The third edge 3 extends to the fifth edge 5 in the direction of the second edge 2.

[0031] The fourth edge 4 and the fifth edge 5 are hollowed to form a guide groove 7, and the trigger block 9 on the buffer 8 slides in the guide groove 7.

[0032] The buffer 8 is embeddedly installed in the accommodating cavity 6, and the buffer 8 is provided with locking bolts 10 at both ends, the locking bolts 10 are pressed on the bottom of the accommodating cavity 6, and the buffer 8 is fixedly installed in the accommodating cavity 6.

[0033] In one embodiment, the buffer 8 is provided with mounting holes 11 on the upper and lower end faces of the body, the mounting holes 11 are fixedly installed with nuts 12, and the locking bolts 10 are screwed with the nuts 12.

[0034] In one embodiment, the locking bolt 10 is a hexagonal bolt.

[0035] In one embodiment, the mounting hole 11 is located in the orthographic projection range of the guide groove 7.

[0036] In one embodiment, the outer side of the second edge 2 and the third edge 3 is provided with anti-skid strips 13.

[0037] In one embodiment, the fourth edge 4 and the fifth edge 5 extend to the outer side to limit the baffle 14.

[0038] In one embodiment, the guide rail is made of aluminum alloy profile.

[0039] Working principle:

[0040] In the case, the guide rail is the basic component of the utility model, which is composed of the first edge 1 extending horizontally and the second edge 2 and the third edge 3 on both sides. The second edge 2 of the guide rail extends to the fourth edge 4 in the direction of the third edge 3, the third edge 3 extends to the fifth edge 5 in the direction of the second edge 2, and the fourth edge 4 and the fifth edge 5 are hollowed to form a guide groove 7. The trigger block 9 on the buffer 8 slides in the guide groove 7.

[0041] The five edges form a containing cavity 6, and the buffer 8 is installed in the containing cavity 6. The guide rail provides a stable installation basis for the buffer through its specific geometry, and after the buffer is installed from the end face, the buffer can freely slide in the guide rail.

[0042] Compared with the simple guide rail opening design in the prior art, the enclosing containing cavity 6 of the utility model can better protect the buffer 8 from external impact or dust pollution. This design improves the service life of the buffer and provides a convenient basic structure for subsequent installation and adjustment. At the same time, the buffer is installed inside the guide rail, which is conducive to maintaining the neatness and beauty of the cabinet body.

[0043] Further, the guide groove 7 provides a clear movement path for the trigger block 9. During the closing of the door, the door leaf contacts the trigger block 9, and the trigger block 9 slides along the guide groove 7, driving the damping mechanism inside the buffer 8 to work, thereby slowing down the closing speed of the door leaf and achieving a smooth and noiseless closing effect.

[0044] Among them, the design of the guide groove 7 ensures the stability of the movement trajectory of the trigger block 9, avoiding the sticking or derailing problems caused by the guide rail opening being too large or the structure being unstable in the prior art. This precise guide mechanism improves the reliability and durability of the system.

[0045] Further, the buffer 8 in the case is installed in the containing cavity 6 in an embedded manner, and lock bolts 10 are provided at both ends of the buffer 8, which are screwed with nuts 12 inside the buffer 8. During installation, the operator places the buffer 8 into the containing cavity 6 from the end face of the guide rail, and by rotating the lock bolts 10, the lock bolts are pressed against the groove bottom of the guide rail, firmly locking the buffer and ensuring that it does not displace during the movement of the door leaf.

[0046] Compared with the installation method in the prior art which requires two-handed operation, the utility model allows the operator to complete the installation with one hand, first placing the buffer and then tightening the bolt, significantly improving the installation efficiency.

[0047] At the same time, the position of the buffer can also be adjusted during installation. The design of the lock bolt 10 and the nut 12 allows the position of the buffer to be adjusted after the bolt is loosened, overcoming the defect that the position cannot be adjusted after being locked in the prior art, and adapting to different door leaf usage requirements. At the same time, the screw connection of the bolt and the nut is more secure than the direct screw fixation in the prior art, reducing the risk of loosening and ensuring the reliability of long-term use.

[0048] The utility model discloses the smooth operation and efficient installation of buffer have been realized, and the containing cavity 6 and guide groove 7 of guide rail design provide the stable movement path for trigger block 9, and the fixed mode of locking bolt 10 and nut 12 ensures the convenience of installation and the adjustability of position.

[0049] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
