Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge. Background Technology

[0002] In traditional technology, hinges are often used to support and secure the door panel to the door frame. However, traditional hinges generally have an unreasonable structure, are difficult to install, lack a safety protection device on the upper hinge, and can cause the door panel to fall off if the spring fails, resulting in a safety accident. They also have limited opening options, failing to meet practical needs. Furthermore, the fit between the upper hinge and the plastic sleeve is prone to failure, and once it fails, the door panel tilts, affecting opening and closing. Therefore, a hinge with authorization number CN205908168U has been proposed. This type of upper hinge requires a safety cover to protect the stable connection between the fixing seat and the hinge. However, in terms of sales and after-sales installation, the safety cover accessory is easy to lose, which is not conducive to after-sales service. Secondly, the existing bushing assembly and shaft combination is not stable. There is a gap between the shaft and the bushing assembly. The shaking shaft will affect the connection with the bearing assembly, thus damaging the entire hinge. Also, since the lower hinge is on the ground, sand and dust can easily be drawn into the lower bushing assembly, causing the rotation to be uneven. To solve the above problems, a modular fixing base is proposed to form an upper hinge with a bushing assembly with limit and a lower hinge with dust protection. Utility Model Content

[0003] This utility model provides a hinge to solve the problems mentioned above.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A hinge, comprising:

[0006] The upper hinge includes an upper shaft fixing seat and an upper shaft sleeve assembly. The upper shaft sleeve assembly is mounted on the upper shaft fixing seat, and the upper shaft fixing seat is provided with a fastener that is movably engaged with the upper shaft sleeve assembly. The fastener rotates on the upper shaft fixing seat through a fixed shaft part and presses against the upper shaft sleeve assembly through a contact part.

[0007] The lower hinge includes a lower shaft fixing seat and a lower shaft sleeve assembly. The lower shaft sleeve assembly is adapted to be installed on the lifting end of the lower shaft fixing seat, and the lower shaft sleeve assembly is provided with a dust cover adapted to the lifting end.

[0008] The upper shaft sleeve assembly is mounted on the upper shaft fixing seat via a shaft. The upper shaft fixing seat has a bearing assembly that snaps onto the shaft. The upper shaft sleeve assembly is equipped with an elastic element and a retaining spring that are adapted to the shaft.

[0009] Furthermore, the bearing assembly includes a ball bearing and a bearing cap.

[0010] Furthermore, the upper bushing assembly has an inner ring post inside, which is located at the open end of the upper bushing assembly and abuts against the limiting elastic element.

[0011] Furthermore, the fastener is adapted to the upper shaft fixing seat, and has a fixed shaft portion that is connected to the upper shaft fixing seat, while a contact portion on one side of the fixed shaft portion engages with the annular groove on the shaft.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] according to Figures 1-5 As shown:

[0028] A hinge, comprising:

[0029] The upper hinge 1 includes an upper shaft fixing seat 11 and an upper shaft sleeve assembly 12. The upper shaft sleeve assembly 12 is mounted on the upper shaft fixing seat 11. The upper shaft fixing seat 11 is provided with a fastener 13 that engages with the upper shaft sleeve assembly 12. The fastener 13 rotates on the upper shaft fixing seat 11 through a fixed shaft part 131 and presses against and engages the upper shaft sleeve assembly 12 through a contact part 132.

[0030] The lower hinge 2 includes a lower shaft fixing seat 21 and a lower shaft sleeve assembly 22. The lower shaft sleeve assembly 22 is adapted to be installed on the lifting end 211 of the lower shaft fixing seat 21. The lower shaft sleeve assembly 22 is provided with a dust cover 23 adapted to the lifting end 211.

[0031] It can be seen that both the upper shaft fixing seat 11 and the lower shaft fixing seat 21 are preferably L-shaped, including a fixed end and a fixed shaft end. The fixed end has several fixing holes for connecting the door structure, while the fixed shaft end is used to connect the movable parts, specifically the upper shaft sleeve assembly 12 and the lower shaft sleeve assembly 22.

[0032] Similarly, both the upper bushing assembly 12 and the lower bushing assembly 22 have external holes;

[0033] Since the external holes and fixing holes are only for fixing purposes, their arrangement and layout will not be the focus of this description.

[0034] The upper shaft sleeve assembly 12 has a built-in shaft 14. The upper shaft sleeve assembly 12 is mounted on the upper shaft fixing seat 11 via the shaft 14. The shaft 14 is engaged with the bearing assembly 15 and rotates. In this structure, the shaft 14 passes through the through hole on the upper shaft fixing seat 11 and is installed inside the upper shaft sleeve assembly 12. The shaft 14 is also equipped with an elastic element and a retaining spring (neither of which is shown in the figure). The elastic element is a spring, and the retaining spring is installed on one side of the elastic element so that the shaft is subjected to the force applied by the elastic element.

[0035] In this structure, the bearing assembly 15 includes a ball bearing and a bearing cap, and the corresponding limiting members are fixed by bolts.

[0036] To limit the elastic element, two sets of retaining springs are typically pressed against and fitted on both sides of the elastic element. In this structure, the upper bushing assembly 12 has an inner ring post 121 inside. The inner ring post 121 is located at the open end of the upper bushing assembly 12. The inner ring post 121 adapts to the shaft and presses against and limits the elastic element. Under normal circumstances, after the shaft 14 is fitted into the upper bushing assembly 12, there is a gap between the shaft and the interior of the upper bushing assembly 12, resulting in insufficient structural stability. After adding the inner ring post 121, the shaft 14 fits against the inner wall of the inner ring post 121, reducing the swaying of the shaft. At the same time, the upper bushing assembly 12 is generally composed of a sleeve, a top cover, and a plate seat. The top cover is movably installed above the sleeve. The inner ring post 121 can be positioned when assembling the sleeve.

[0037] In this structure, the bearing assembly 15 is located below the fastener 13.

[0038] The fastener 13 is adapted to the upper shaft fixing seat 11 and is connected to the upper shaft fixing seat 11 by a fixed shaft part 131. The fixed shaft part 131 is connected to a screw, which allows the fixed shaft part 131 to rotate in an orientation. The contact part 132 on one side is concave and fits into the annular groove 141 on the shaft 14. Finally, the fastener 13 is also provided with a toggle part 133, which is in the form of a vertical plate as shown in the figure. The contact part 132 is opposite to the bearing assembly 15.

[0039] In order to better position the fastener 13, there is an adapter 111 on the upper shaft fixing seat 11, and the fastener 13 has a protrusion. When rotated to the adapter 111, the protrusion will be inserted into the adapter 111, giving the operator a feedback signal of engagement.

[0040] The lower shaft fixing seat 21 is also provided with a limiting end 212, and the lifting end 211 is adapted to the limiting end 212 through the gear sleeve 24.

[0041] The dust cover 23 is movably connected to the lower bushing assembly 22. Specifically, the inner wall of the dust cover 23 has spaced edges or is linked by holes.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
