Description

[Technical Field]

[0001] This utility model mainly relates to a belt tension adjustment device. [Background Technology]

[0002] To ensure the stability and smoothness of sliding doors during the sliding process, a tensioning device is usually installed. The tensioning device is used to adjust the tension of the drive belt that drives the sliding door, thereby ensuring the smooth movement of the sliding door.

[0003] Common tensioning devices include adjusting bolts and driven pulleys. The driven pulley is used to attach the drive belt, and rotating the adjusting bolt can change the position of the driven pulley, thereby controlling the tension of the drive belt. However, current tensioning devices lack resilience, so they can only be adjusted slowly by hand, which is troublesome and time-consuming to install and not conducive to rapid on-site installation. In view of this, we propose a new tensioning device solution. [Utility Model Content]

Detailed Implementation Methods

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The preferred embodiment provided by this utility model is as follows: Figures 1-5 As shown, a belt tension adjustment device includes a base 1, an adjusting component 2, an adjusting bolt 3, an adjusting spring 4, an adjusting nut 5, and a locking component 6;

[0027] The base 1 has a cavity 11 and a snap-fit ​​groove 12. The snap-fit ​​groove 12 passes through the base 1, and the cavity 11 communicates with the snap-fit ​​groove 12. The adjusting bolt 3 is connected to the adjusting nut 5 and placed together in the cavity 11. The locking member 6 is inserted into the snap-fit ​​groove 12 and connected to the adjusting bolt 3. The locking member 6 is U-shaped in general. The end of the adjusting bolt 3 is provided with an annular groove 31 for the locking member 6 to connect with the locking part, so as to limit the rotation of the adjusting bolt 3 in the cavity 11 by the locking member 6.

[0028] The adjusting component 2 is provided with an access hole 25, the adjusting bolt 3 passes through the access hole 25, the adjusting spring 4 is sleeved on the adjusting bolt 3, and the two ends of the adjusting spring 4 abut against the adjusting nut 5 and the adjusting component 2 respectively, so as to adjust the position of the adjusting component 2 by adjusting the adjusting spring 4; the baffle part 22 of the adjusting component 2 blocks the locking groove 12 to restrict the locking component 6 from falling out of the base 1.

[0029] The base 1 has a locking groove 13 and an expansion groove 14 at its bottom. The end of the expansion groove 14 is open, and a mating block 7 is inserted into the expansion groove 14. The mating block 7 is fixed inside the expansion groove 14 and partially protrudes from the base 1. The part of the mating block 7 protruding from the base 1 has a connecting hole 71 for connecting other components. The belt tension adjustment device is installed on the guide rail. The bottom end of the locking groove 13 is open, and a screw is inserted into the locking groove 13 and abuts against the guide rail from the open bottom end of the locking groove 13 to fix the position of the base 1.

[0030] The top of the cavity 11 is open, and the adjusting part 2, which is connected to the adjusting bolt 3, covers the open top of the cavity 11, hiding the adjusting bolt 3 and other components, thus improving the overall aesthetics. The base 1 also protects the components. The cross-section of the cavity 11 and the cross-section of the adjusting nut 5 are both square, and the cross-sectional dimensions of the adjusting nut 5 correspond to the cross-sectional dimensions of the cavity 11 to restrict the rotation of the adjusting nut 5 within the cavity 11.

[0031] The adjusting component 2 includes a connector portion 21 and a baffle portion 22. The connector portion 21 is located at one end of the baffle portion 22, and an access hole 25 is provided in the connector portion 21 and penetrates through the connector portion 21. The connector portion 21 is located at the bottom end of the baffle portion 22, and a pulley 23 is provided at the top end of the baffle portion 22. The connector portion 21 and the pulley 23 are located at the same end of the adjusting component 2, and a strip groove 24 is provided at the other end of the adjusting component 2.

[0032] The base 1 is screwed with a positioning screw 15, and the positioning screw 15 passes through the strip groove 24; the base 1 is provided with a first locking hole 16 and a second locking hole 17, the positioning screw 15 is screwed into the first locking hole 16, and the screw for fixing the docking block 7 is screwed into the second locking hole 17.

[0033] Due to the connection limitation between the locking component 6 and the annular groove 31, the adjusting bolt 3 can automatically rotate within the cavity 11, changing its position within the cavity 11. Simultaneously, the adjusting bolt 3 is screwed with an adjusting nut 5, which is restricted from rotation by the wall of the cavity 11. Therefore, when the adjusting bolt 3 rotates, the adjusting nut 5 moves along the adjusting bolt 3. The two ends of the adjusting spring 4 abut against the adjusting nut 5 and the connector 21 respectively. As the adjusting nut 5 moves, the adjusting spring 4 deforms, thereby pushing the adjusting component 2 to move and changing the overall length of the belt tension adjusting device. The positioning screw 15 connects to the strip groove 24, limiting the range of movement of the adjusting component 2. The extended mounting docking block 7 increases functionality and facilitates accessory connection.
