Description

Technical Field

[0001] This utility model relates to the technical field of hinges, specifically to a novel spring-positioned hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solid parts and allow them to rotate relative to each other. It typically consists of two metal or non-metal blades connected by a central axis, allowing the connected parts to rotate freely around that axis. An automotive hinge is a mechanical device used to connect the car body and the car door; its main function is to ensure that the door can open and close smoothly and easily.

[0003] The current technology still has the following areas for improvement: Most hinges used in automobiles currently use the force of a spring to open and close. Because the spring requires sufficient space to accommodate its stop foot, in order to ensure that the spring stop foot can be stably fixed in a specific position on the hinge, the stop foot mounting surface needs to be flat. The space of the spring stop foot on the mounting surface is very limited. Therefore, when the hinge is opened to its limit, the spring stop foot can easily come out, causing the hinge to malfunction and have a short service life. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a novel spring-positioned hinge that can prevent the hinge from malfunctioning due to the spring stop foot dislodging when the hinge is opened to its limit, thereby extending the service life of the hinge.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A novel spring-positioning hinge includes a first bracket, a second bracket, a hinge shaft, and a spring, wherein multiple springs are provided and multiple springs are sleeved on the hinge shaft;

[0007] The first bracket has a stop surface and two first mounting blocks on the side near the hinge shaft. The two first mounting blocks are located on both sides of the stop surface. The stop surface is provided with a plurality of barbs. The first bracket is rotatably connected to the hinge shaft through the first mounting blocks.

[0008] The second bracket is provided with a plurality of second mounting blocks and a third mounting block on the side near the hinge axis, and the second bracket is rotatably connected to the hinge axis through the second mounting blocks;

[0009] One end of the spring is provided with a stop foot, which is L-shaped, and the other end of the spring is provided with a bent section, which is L-shaped.

[0010] Preferably, the plurality of barbs are evenly distributed and arranged perpendicular to the first bracket.

[0011] Preferably, the springs are evenly distributed, and the position of the stop foot corresponds to the position of the barb block.

[0012] Preferably, the plurality of second mounting blocks and the plurality of third mounting blocks are arranged in an alternating pattern.

[0013] Preferably, the position of the bent section corresponds to the position of the second mounting block.

[0014] Preferably, the stop surface is wavy.

[0015] Preferably, the third mounting block is configured in a downwardly curved hook shape.

[0016] Preferably, the first bracket is provided with a plurality of first mounting holes, and the second bracket is provided with a plurality of second mounting holes, wherein the positions of the first mounting holes correspond to the positions of the second mounting holes.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By setting the second bracket, the stop foot and the bending section, the technical effect that can be achieved is to make the spring stably fixed in the designated position of the first bracket and the second bracket, and to avoid the hinge function failure caused by the spring being displaced when the hinge is opened and closed. Multiple second mounting blocks and multiple third mounting blocks are arranged in an alternating manner, so that the second bracket can stably connect the hinge shaft and the parts to be connected at the same time. The third mounting block is set in a downwardly bent hook shape, which makes it easy to make the second bracket stably fixed on the parts to be connected.

[0019] (2) By setting the first bracket, barb block and stop foot, the technical effect that can be achieved is that the barb block is set perpendicular to the first bracket, and the position of the stop foot corresponds to the position of the barb block. When the hinge is opened to the limit, the stop foot can hook the barb block, thus avoiding the phenomenon that the stop foot of the spring disengages from the stop surface when the hinge is opened to the limit, causing the hinge to fail and extending the service life of the hinge.

[0030] Reference Figures 1 to 4 The present invention discloses a novel spring-positioning hinge, comprising a first bracket 1, a second bracket 2, a hinge shaft 3 and a spring 4, wherein multiple springs 4 are provided and multiple springs 4 are sleeved on the hinge shaft 3;

[0031] The first bracket 1 is provided with a stop surface 101 and two first mounting blocks 104 on the side near the hinge shaft 3. The two first mounting blocks 104 are located on both sides of the stop surface 101. Multiple barbs 102 are provided on the stop surface 101. The first bracket 1 is rotatably connected to the hinge shaft 3 through the first mounting blocks 104.

[0032] The second bracket 2 is provided with a plurality of second mounting blocks 202 and third mounting blocks 203 on the side near the hinge shaft 3. The second bracket 2 is rotatably connected to the hinge shaft 3 through the second mounting blocks 202.

[0033] One end of the spring 4 is provided with a stop foot 401, which is L-shaped. The other end of the spring 4 is provided with a bending section 402, which is L-shaped. By providing the stop foot 401 and the bending section 402, the spring 4 can be stably fixed at the designated position of the first bracket 1 and the second bracket 2, so as to avoid the spring 4 from being displaced when the hinge is opened and closed, which would cause the hinge to malfunction.

[0034] Reference Figures 1 to 4 Multiple barbs 102 are evenly distributed and set perpendicular to the first bracket 1; springs 4 are evenly distributed, and the position of the stop foot 401 corresponds to the position of the barb 102. When the hinge is opened to the limit, the stop foot 401 can hook the barb 102, preventing the stop foot 401 of the spring 4 from dislodging from the stop surface 101 when the hinge is opened to the limit, thus causing the hinge to malfunction and extending the service life of the hinge; multiple second mounting blocks 202 and multiple third mounting blocks 203 are staggered, so that the second bracket 2 can simultaneously and stably connect the hinge shaft 3 and the parts to be connected; the position of the bent section 402 corresponds to the position of the second mounting block 202.

[0035] Reference Figures 1 to 4 The stop surface 101 is wavy; the third mounting block 203 is hook-shaped with a downward curve, which makes it easy to fix the second bracket 2 stably on the component to be connected; the first bracket 1 is provided with a plurality of first mounting holes 103, and the second bracket 2 is provided with a plurality of second mounting holes 201, the positions of the first mounting holes 103 and the positions of the second mounting holes 201 are corresponding.

[0036] The working principle and usage process of this utility model are as follows: The second bracket 2 is positioned and installed on a component that needs to be connected through the third mounting block 203. This component is a rotatable component. The second bracket 2 is fixed to this component through the second mounting hole 201. Then, the first bracket 1 is fixed to another component that needs to be connected through the first mounting hole 103. This component is a fixed component, so that the two components are connected by a hinge.

[0037] When the rotatable part rotates to the maximum rotatable angle and drives the second bracket 2 to open to the limit, the stop foot 401 hooks the barb block 102 to prevent the stop foot 401 from coming off and causing the hinge function to fail.
