Description

Technical Field

[0001] The utility model relates to the technical field of furniture slide rails, in particular to a furniture slide rail buffer structure. Background Art

[0002] Furniture refers to a large category of equipment and facilities that are indispensable for humans to maintain normal life, engage in production practice and carry out social activities. Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties and different uses. It is an important foundation for establishing a working and living space. Furniture doors in furniture require pulleys when in use. Existing pulleys are generally fixed at the upper and lower ends of the furniture doors. Under the action of the pulleys, the furniture doors slide in the slide rails to facilitate opening and closing of the cabinet doors.

[0003] When the cabinet door is closed, the existing furniture pulleys will collide with each other, which affects the service life of the pulleys. Generally, a damping effect is achieved through structures such as damping. However, there is only a single damping structure, which is relatively simple in structure. The single damping bears a large pressure, which can easily cause damage to the damping. The existing furniture pulley buffer structure needs to be fixed with screws during installation, and both installation and disassembly require the use of tools, which is very troublesome. Therefore, a furniture slide rail buffer structure is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a furniture slide rail buffer structure to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A furniture slide rail buffer structure comprises a slide rail, wherein one end of the slide rail is provided with a slide groove, a pulley group is slidably connected inside the slide groove, one end of the pulley group is fixedly connected to a buffer block, the inside of the slide groove is slidably connected to a fixed shell located between the two pulley groups, a first fixing hole is provided on the outside of the slide rail, a second fixing hole is provided on the outside of the fixed shell, one end of the fixed shell is provided with a limiting groove, a fixing plate located in the middle position of the fixed shell is fixedly connected inside the limiting groove, a damper is fixedly connected to one side of the fixing plate, a spring located on the outside of the damper is fixedly connected to one side of the fixing plate, and an end of the damper away from the fixing plate is fixedly connected to a support plate.

[0008] Preferably, the fixing card has three length models, and the sizes of the fixing cards are longer than one another.

[0009] Preferably, the damper, spring and support plate form a group, with two groups in total, and are symmetrically arranged on both sides of the fixing plate.

[0010] Preferably, the inner size of the limiting groove is consistent with the outer size of the buffer block, and the length of the buffer block is greater than the length from the support plate to the opening of the limiting groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0024] See also Figure 1-6 , the utility model provides a technical solution:

[0025] A furniture slide rail buffer structure includes a slide rail 1, a slide groove 2 is provided at one end of the slide rail 1, a pulley group 3 is slidably connected inside the slide groove 2, a buffer block 4 is fixedly connected to one end of the pulley group 3, and a fixed shell 6 located between the two pulley groups 3 is slidably connected inside the slide groove 2. A first fixing hole 5 is provided on the outside of the slide rail 1, a second fixing hole 7 is provided on the outside of the fixed shell 6, a limiting groove 14 is provided at one end of the fixed shell 6, a fixing plate 9 located in the middle position of the fixed shell 6 is fixedly connected inside the limiting groove 14, a damper 10 is fixedly connected to one side of the fixed plate 9, a spring 11 located outside the damper 10 is fixedly connected to one side of the fixed plate 9, and the end of the damper 10 away from the fixed plate 9 is fixedly connected to a support plate 13.

[0026] The first fixing hole 5 and the second fixing hole 7 are internally engaged and connected with a fixing card 8, one end of the fixing card 8 is fixedly connected to a spring leaf 12 located on the inner side of the fixed shell 6, and there are three length models of the fixing card 8, and the sizes of the fixing cards 8 are longer than one another. The damper 10, the spring 11 and the support plate 13 are a group, with a total of two groups, and are symmetrically arranged on both sides of the fixing plate 9. The inner size of the limiting groove 14 is consistent with the outer size of the buffer block 4, and the length of the buffer block 4 is greater than the length from the support plate 13 to the opening of the limiting groove 14.

[0027] Working process: When a furniture slide rail buffer structure is needed, first engage the fixed shell 6 into the slide groove 2 of the slide rail 1, then move the fixed shell 6 to the middle position so that the first fixing hole 5 and the second fixing hole 7 overlap, and then insert three fixing cards 8 from the outside to the inside, from short to long. Due to the different lengths of the fixing cards 8, the lengths of the springs 12 on the fixing cards 8 protruding from the inside of the fixed shell 6 will also be different. The fixed shell 6 is fixed to the inside of the slide rail 1 through the fixing cards 8. The buffer structure can be fixed by directly inserting the fixing cards 8. For disassembly, just pull out the fixing cards 8. After installation, install the pulley assembly 3. After installing the slide rail 1, it can start normal use. As the cabinet door is closed, the pulley block 3 will drive the buffer block 4 to enter the inside of the limit groove 14 from both ends. Before the buffer block 4 contacts the damper 10, the buffer block 4 will contact the three springs 12 protruding from the fixed shell 6 in turn, and will first contact the spring 12 with the least protrusion. The buffer block 4 is squeezed by the springs 12 of different lengths, thereby reducing the moving speed of the pulley block 3 and reducing the impact force on the subsequent buffer structure. As the pulley block 3 continues to move, the buffer block 4 will contact the support plate 13, and the pulley block 3 will be finally buffered by the spring 11 and damper 10 arranged behind the support plate 13.
