Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and more specifically to a hinge that is easy to assemble and disassemble. Background Technology
[0002] A hinge is a component used to connect two parts and allow them to rotate relative to each other and open. Hinges are used in many products in daily life, such as wardrobes and other household appliances, such as microwave ovens. Current hinge technology generally includes a hinge base, a hinge plate, a return pull element, and a buffer positioning element. The hinge plate is installed on the cabinet door, and the hinge base is installed on the cabinet body.
[0003] Hinges are also used in some small household appliances, such as microwave ovens and ovens. Because the doors of small appliances are relatively thin, they need to be easy to disassemble and assemble. Utility Model Content
[0004] This invention provides a hinge that is easy to assemble and disassemble.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hinge that is easy to assemble and disassemble, comprising: a shell, a first buffer assembly, a second buffer assembly, and a head assembled on the shell; the head is L-shaped, and the bend of the head constitutes the position for the latch assembly; one end of the head is rotatably connected to the shell, and one end of the head is rotatably connected to the first buffer assembly.
[0006] The head is provided with an L-shaped groove, and the latch is installed in the L-shaped groove by a first rivet. The latch is rotated to move the first rivet to the stop end of the L-shaped groove, and the latch abuts against the outer shell to position the head relative to the outer shell at the installation angle.
[0007] In a preferred embodiment of this invention, the ratio of the lateral length to the longitudinal length of the head is 1:0.9.
[0008] As a preferred embodiment of the present invention, the first buffer assembly includes: a tension spring and an inner support;
[0009] The head is rotatably connected to the end of the inner bracket, and the upper end of the inner bracket is provided with a second rivet, which is installed in the first slot of the outer shell.
[0010] The upper end of the tension spring is confined to the outer shell, and the lower end is connected to the second rivet at the upper end of the inner bracket;
[0011] During the swinging motion of the head, the inner support moves within the outer shell, causing the tension spring to deform.
[0012] As a preferred embodiment of the present invention, the second buffer assembly includes: a compression spring, a compression spring pin, and a pulley;
[0013] The spring pin is confined to the housing and is movable. The spring is sleeved on the spring pin. The pulley is mounted on the third rivet, which is installed in the second groove of the housing.
[0014] As a preferred embodiment of this utility model, a limiting plate is provided inside the outer shell, and the limiting plate is provided with a groove. The upper end of the compression spring needle passes through the groove, and the pulley is located at the lower end of the compression spring needle. The lower end of the compression spring needle is pressed against the pulley by the elastic force of the compression spring.
[0015] In a preferred embodiment of this invention, the pulley is pressed against the end face of the head.
[0016] In a preferred embodiment of this invention, during the head swinging process, the pulley moves along the end face and pushes the compression spring needle.
[0017] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:
[0018] 1. The hinge structure of this utility model is simple, easy to manufacture, and low in cost. It is suitable for assembling oven doors that are relatively thin and require easy disassembly and assembly, as well as oven doors that require relatively high locking force.
[0019] 2. The hinge of this utility model features an L-shaped groove at its head, minimizing the space required for the latch to rotate and ensuring it can slide into its stop position to secure the latch. Similarly, when disassembly is required, the latch slides and rotates within the L-shaped groove, providing counter-support and reaching a certain angle to create the door's disassembly angle. This design aims to provide convenient assembly and disassembly. By reserving sufficient space for latch installation, the degree of freedom of the latch during assembly and disassembly is effectively constrained, thereby ensuring the reliability of the assembly and disassembly process.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0032] A hinge that is easy to assemble and disassemble, such as Figure 1-5 As shown, it includes: a housing 100, a first buffer assembly 200, a second buffer assembly 300, and a head 400 assembled on the housing 100; the head 400 is L-shaped, and the bend of the head 400 forms the position for mounting the latch 500; one end of the head 400 is rotatably connected to the housing 100, and one end of the head 400 is rotatably connected to the first buffer assembly 200; the head 400 is provided with an L-shaped groove 410, and the latch 500 is installed in the L-shaped groove 410 by a first rivet 510; the latch 500 rotates to move the first rivet 510 to the stop end of the L-shaped groove 410, and the latch 500 abuts against the housing 100 to position the head 400 relative to the housing 100 at an installation angle.
[0033] The outer shell 100 is elongated and made of high-hardness metal material. One end of the head 400 is rotatably connected to one end of the outer shell 100 by a pin and a flower wheel. During the swinging process of the head 400, the first buffer component 200 and the second buffer component 300 play a buffering role, realizing the slow opening and closing of the head 400.
[0034] Furthermore, when the hinge is in the closed position, the first buffer assembly 200 also acts as a tensioning element, ensuring that the door and body of the oven are tightly closed when the hinge is used.
[0035] Furthermore, such as Figure 5As shown, the L-shaped groove 410 has a stop end 411 and a mounting end 412. During the assembly of small household appliances such as microwave ovens and ovens, the hinge swings the head 400 to... Figure 5 At the angle shown, while rotating the latch 500, the first rivet 510 moves from the mounting end 412 to the stop end 411, and the latch 500 abuts against the outer casing 100, positioning the head 400 at the indicated angle. Figure 5 The angle and direction hinge is installed in small appliances such as microwave ovens and ovens. The lock 500 requires little space to rotate, ensuring that the lock 500 can slide into the stop end 411 to maintain its function. Similarly, when disassembly is required, the lock 500 slides and rotates in the L-shaped groove 410 to provide counter-support and reach a certain angle to form the door disassembly angle. This design aims to provide convenient disassembly and assembly operations. By reserving enough space to install the lock 500, the freedom of the lock 500 in the disassembly and assembly state can be effectively constrained, thereby ensuring the reliability of the disassembly and assembly state.
[0036] Furthermore, such as Figure 2 As shown, the latch 500 has an abutment portion 501 that protrudes and is disposed thereon. The abutment portion 501 abuts against the housing 100, thereby holding the head 400 in place. Figure 5 The installation angle shown.
[0037] In one embodiment, the ratio of the lateral length to the longitudinal length of the head 400 is 1:0.9; Figure 3 The orientation is described as follows: the horizontal direction is the lateral length of the head 400, and the vertical direction is the longitudinal length of the head. The head 300 is L-shaped, and the lateral and longitudinal length structures are similar. When the head 400 swings relative to the outer shell 100, the swing radius is small.
[0038] In one implementation, such as Figure 3-5 As shown, the first buffer assembly 200 includes: a tension spring 210 and an inner support 220;
[0039] The inner support 220 is made of metal and is roughly elongated.
[0040] The head 400 is rotatably connected to the end of the inner bracket 220. The upper end of the inner bracket 220 is provided with a second rivet 221, which is installed in the first slot 110 of the outer shell 100.
[0041] The upper end of the tension spring 210 is confined to the outer shell 100, and the lower end is connected to the second rivet 221 at the upper end of the inner bracket 220;
[0042] During the swinging process of the head 400, the inner support 220 moves within the outer shell 100, and the tension spring 210 deforms.
[0043] Specifically, the top 400 from Figure 3 Position rotated to Figure 4 When in position, the head 400 rotates counterclockwise. During the rotation of the head 400, the inner support 220 moves to the left, and the tension spring 210 is stretched. The tension spring 210 then provides a pulling force to the right, causing the head 400 to rotate slowly.
[0044] In one embodiment, the second buffer assembly 300 includes: a compression spring 310, a compression pin 320, and a pulley 330; the compression pin 320 is confined to the housing 100 and is movable, the compression spring 310 is sleeved on the compression pin 320, the pulley 330 is mounted on a third rivet 331, and the third rivet 331 is mounted in the second groove 120 of the housing 100.
[0045] Furthermore, a limiting plate 130 is provided inside the outer shell 100. The limiting plate 130 is provided with a groove. The upper end of the compression spring needle 320 passes through the groove, and the pulley 330 is located at the lower end of the compression spring needle 320. The lower end of the compression spring needle 320 is pressed against the pulley 330 by the elastic force of the compression spring 310.
[0046] When the spring needle 320 moves, the movement is more stable with the assistance of the groove.
[0047] Furthermore, the pulley 330 is pressed against the end face 401 of the head 400, and the end face 401 is an arc-shaped surface; specifically, as shown... Figure 2 As shown, end face 401 is an irregular arc-shaped surface.
[0048] Furthermore, such as Figure 3 As shown, at this time, pulley 330 is pressed against end face 401 of head 400, and head 400 rotates from the closed position to the open position, that is, rotates counterclockwise. During the rotation, head 400 pushes spring pin 320 to the right through pulley 330, spring 310 is compressed, and spring 310 provides a leftward elastic force to press pulley 330 against end face 401; during this process, tension spring 210 is stretched, providing a rightward pulling force to slowly open head 400.
[0049] like Figure 4 As shown, head 400 needs to be from Figure 4 Rotate to the open position Figure 3 In the closed position shown, the head 400 rotates clockwise. During rotation, the head 400 pushes the spring pin 320 to the right via the pulley 330, compressing the spring 310. The spring 310 provides a leftward elastic force, pressing the pulley 330 against the end face 401. During this process, the tension spring 210 provides tension to assist the head 400 in rotating, while the spring 310 causes the head 400 to close slowly.
[0050] Therefore, the swing of the head 400 drives the first buffer component 200 and the second buffer component 300 to operate, and work together to balance the opening and closing and the movement state of the door. When the head 400 reaches 90 degrees, the head 400 changes its R angle and the pulley 330 generates the furnace door locking force under the action of the compression spring 310. This design can provide a corresponding stable locking force and furnace door balancing force under narrow furnace door conditions, and the shape of the components can be adjusted as needed.
[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
