Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of buffer hinge, especially to a buffer damping piece mounting sleeve and buffer hinge assembly structure. BACKGROUND

[0002] The hinge is often used as the connector of the opening and closing structure, which can realize the opening and closing of the opening and closing structure around the shaft. In order to realize the buffering effect of the opening and closing process of the opening and closing structure, adding a buffer assembly in the hinge is an effective setting scheme.

[0003] At present, the hinge with a single torsional spring is prone to abnormal friction feeling in the opening and closing process of the hinge. The improved hinge structure is compact, and the moment arm of the hinge arm is lengthened. Therefore, the buffer hinge with a double torsional spring can form a stable elastic support structure. In the patent with the patent number CN221220136U (patent name: a buffer hinge) of the applicant's prior application, an elastic structure formed by a double torsional spring, an inner hinge piece and a hinge arm is disclosed. However, in actual use, the double torsional spring will swing horizontally left and right in the hinge arm during the opening and closing action. Since there is a gap between the mounting sleeve and the hinge arm, the double torsional spring abutting against the support bump of the inner hinge piece has the possibility of sliding inward. This risk can easily cause the hinge to lose its effectiveness. Although CN221220136U proposes to increase the side torsional arm cross-sectional area of the double torsional spring, this avoidance method increases the material process and requires customization of the double torsional spring, which still has the possibility of dislocation.

[0035] Embodiment 1:

[0036] In order to solve the problem that the spring member is easily deflected and then dislocated during the use of the current buffer hinge, please refer to Figures 1-5The embodiment provides a buffer damping piece mounting sleeve 10, which comprises a mounting sleeve body 11, the mounting sleeve body 11 is a main part of the mounting sleeve 10 and is used for realizing the main function of the mounting sleeve 10 and plays a bearing role, and the mounting sleeve 10 is used for completing various functions of the mounting sleeve 10 by arranging specific functional parts such as an assembly groove 12, a sliding groove 13 and a limiting boss 14 on the mounting sleeve body 11. Wherein, the mounting sleeve body 11 is provided with the assembly groove 12 on one end bottom surface, the assembly groove 12 is mainly used for mounting a buffer damping piece 20, the buffer damping piece 20 adopts an existing damping piece capable of realizing a buffering function, for example, the buffer damping piece 20 adopts a damping oil cylinder, the damping oil cylinder comprises a cylinder body and a damping rod, the damping rod is movable in and out of the oil cylinder and plays a role of providing damping force. The buffer damping piece 20 is mounted in the assembly groove 12 through a fixed end, and an active end is outwardly extended through an opening of the assembly groove 12 and cooperates with a mounting pressing plate 30.

[0037] The sliding groove 13 is arranged on two horizontal sides of the mounting sleeve body 11 and is arranged from the bottom surface direction of the assembly groove 12 to another direction, the sliding groove 13 is mainly used for cooperating with the mounting pressing plate 30 of the buffer damping piece 20, so that a sliding arm 32 of the mounting pressing plate 30 can slide in the sliding groove 13. For example, when the buffer hinge is in action, the mounting pressing plate 30 is driven to be lowered to the buffer damping piece 20, and the active end of the buffer damping piece 20 is pressed, and in the process, the sliding arm 32 slides in the sliding groove 13 and plays a role of guiding the mounting pressing plate 30.

[0038] As an important point of the embodiment, the limiting boss 14 is arranged in the mounting sleeve 10, the limiting boss 14 is outwardly protruded from the bottom end of the sliding groove 13 to the side, wherein the bottom end refers to that the limiting boss 14 is arranged on the bottom surface close to the opposite side of the assembly groove 12, that is, preferably, the limiting boss 14 is arranged on the side of the mounting sleeve body 11 and is arranged close to the bottom surface of the other end of the mounting sleeve body 11, and the arrangement is mainly determined by the role. Specifically, the limiting boss 14 is used for reducing the gap between the mounting sleeve 10 and a hinge arm shell 40, thereby horizontally limiting a double torsion spring 60 mounted between the mounting sleeve 10 and the hinge arm shell 40, so that the double torsion spring 60 can be accurately connected with an inner hinge piece 50, the situation that the double torsion spring 60 is offset and then falls into the supporting boss 51 of the inner hinge piece 50 is avoided, the possible risk of the product in use is avoided, and the reliability of internal assembly of the buffer hinge is improved.

[0039] As one of the preferences, the limiting boss 14 is arranged on two horizontal sides adjacent to the assembly groove 12 of the mounting sleeve body 11, and the arrangement is mainly used for limiting two side torsion arms 62 of the double torsion spring 60, so that the double torsion spring 60 cannot be leftwardly or rightwardly offset in the hinge arm shell 40.

[0040] Preferably, the material of the mounting sleeve 10 in the embodiment includes plastic.

[0041] Please see Figures 1-5 , some specific embodiments in the embodiment are provided below.

[0042] In other specific settings of the mounting sleeve 10, as one of the preferences of the embodiment, the mounting sleeve 10 is provided with a support platform 15 for limiting cooperation with the double torsion spring 60. Specifically, the support platform 15 is protruded outward from the other end of the bottom surface of the mounting sleeve 10 and is provided with a support seat 151 for limiting the double torsion spring 60. Functionally, the support platform 15 is arranged at the other end of the mounting platform opposite to the assembly groove 12, and is mainly used for cooperating with the double torsion spring 60 after assembly to limit it in the circumferential direction. For example, the support seat 151 is arranged as a recessed avoidance position, and the double torsion spring 60 further includes a middle torsion arm 61, which is limited to be arranged on the avoidance position and will abut against the avoidance position when rotated to a certain angle.

[0043] In the arrangement of the sliding groove 13, as a preference, the sliding groove 13 is used to assemble the mounting pressure plate 30 of the buffer damping member 20, and the sliding groove 13 is further provided with a limiting seat for limiting the mounting pressure plate 30 of the buffer damping member 20. The limiting seat is mainly used for cooperating with the sliding arm 32 of the mounting pressure plate 30 to limit the mounting pressure plate 30 from being detached from the sliding groove 13 after assembly, so as to improve the reliability thereof.

[0044] As a further optimization of the above-mentioned scheme, please refer to Figures 1-4 , the limiting seat includes an avoidance slot 16 formed by penetrating inward from the bottom surface of the sliding groove 13, which cooperates with the clamping block of the mounting pressure plate 30 to limit the sliding of the mounting pressure plate 30 in the sliding groove 13. The avoidance slot 16 is a through slot that penetrates the side surface of the mounting sleeve 10, which is formed by punching through the side surface and the top surface from the side surface to the obliquely upward direction. This slotting method is reliable and efficient, and the limiting effect of the avoidance slot 16 is superior.

[0045] As one of the alternative schemes of the above-mentioned avoidance slot 16, please refer to Figure 5 , the limiting seat further includes a sliding rail groove seat 17 protruded from the top / bottom of the sliding groove 13, which forms a sliding rail in the middle through the protrusion of the two end portions for limiting cooperation with the mounting pressure plate 30. This design has the advantage that the mounting sleeve 10 can be directly integrally formed, which simplifies the processing flow and achieves the same limiting effect.
