[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 , which is an adjustable torque hinge of an embodiment of the utility model, includes a first hinge 10 and a second hinge 20 that are matched and hinged, and a tensioning component 30 that penetrates the first hinge 10 and the second hinge 20 at the same time.

[0029] The first hinge 10 includes a first mounting plate 11 and a middle sleeve 12 connected to the middle of one side of the first mounting plate 11; the middle sleeve 12 is provided with a middle through hole 13 along its axis, and the middle through hole 13 is a slotted hole.

[0030] The second hinge 20 includes a second mounting plate 21 and side sleeves 22 connected to opposite ends of one side of the second mounting plate 21; the two side sleeves 22 are used to match and accommodate the middle sleeve 12, and the side sleeves 22 and the middle sleeve 12 are coaxially arranged.

[0031] In this embodiment, one side sleeve 22 is provided with a side through hole 23 along its axis, and the other side sleeve 22 is provided with an assembly hole 24 along its axis. The side through hole 23 is a slotted hole, and the assembly hole 24 is a circular stepped hole.

[0032] The tensioning assembly 30 includes a central shaft 31, an adapter sleeve 32 coaxially mounted in the middle of the central shaft 31, a fixed shaft head 33 fixedly connected to one end of the central shaft 31, a nut 34 screwed to the other end of the central shaft 31, and springs 35 mounted on opposite sides of the adapter sleeve 32. The adapter sleeve 32 and the central shaft 31 can both rotate and slide relative to each other. One spring 35 is sandwiched between the fixed shaft head 33 and the adapter sleeve 32, and the other spring 35 is sandwiched between the adapter sleeve 32 and the nut 34. When in use, the nut 34 can be screwed to drive the adapter sleeve 32 to move along the axis of the central shaft 31 to adjust the tension of the spring 35. By changing the friction force of the two springs 35 on the adapter sleeve 32, the effect of adjusting the torque is achieved, which greatly improves the versatility and practicality of the hinge.

[0033] like Figure 3 and Figure 5 As shown, an annular recess 310 is provided along the circumference of the central axis 31 at the middle position. The adapter sleeve 32 is provided with an axial through hole 321 along its axial centerline direction, and the axial through hole 321 is used for the central axis 31 to pass through. A side cut opening 322 is provided on one side of the adapter sleeve 32, and the side cut opening 322 is connected inwardly to the axial through hole 321. During assembly, the central axis 31 is penetrated by the axial through hole 321, and the position of the annular recess 310 corresponds to the position of the side cut opening 322. At this time, the C-shaped retaining spring 323 is used to penetrate the side cut opening 322 and then snap it into the inside of the annular recess 310, so that the central axis 31 and the adapter sleeve 32 can be rotatably installed. Furthermore, the opening width of the side cut opening 322 is greater than the thickness of the C-shaped retaining spring 323, so that the adapter sleeve 32 can move a certain amount along the axial centerline direction of the central axis 31 to squeeze or relax the spring 35 to adjust the torque. During the actual assembly, the middle sleeve 12 and the two side sleeves 22 are placed in correspondence, and then the entire tensioning assembly 30 with the torque adjusted is inserted from the side through hole 23 until the fixed shaft head 33 is completely accommodated in the side through hole 23 and the nut 24 is completely accommodated in the assembly hole 24, and the assembly is completed. At this time, the adapter sleeve 32 is accommodated in the middle through hole 13.

[0034] Please refer again Figure 5The tensioning assembly 30 further includes two reinforcing sheets 36 sleeved on the central shaft 31, one reinforcing sheet 36 is sandwiched between the fixed shaft head 33 and the spring 35, and the other reinforcing sheet 36 is sandwiched between the spring 35 and the nut 34. In this embodiment, the reinforcing sheet 36 is provided in an oval sheet shape, and the reinforcing sheet 36 is used to be assembled into the interior of the middle through hole 13, which can effectively improve the connection stability between the tensioning assembly 30 and the first hinge 10, and improve the damping feeling during rotation.

[0035] The above-mentioned adjustable torque hinge has a simple structure and is easy to use. The adapter sleeve 32 can be rotatably installed on the central shaft 31. The nut 34 can be used to adjust the tension of the spring 35 on the opposite sides of the adapter sleeve 32, thereby achieving adjustable torque, which greatly improves the versatility and practicality of the hinge.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
