Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and more specifically to oven hinges. Background Technology

[0002] Traditional oven hinge locking structures are limited by space and usually have a pin to limit the head to achieve a reverse support pre-installation function. This structure requires additional parts and is inconvenient to operate. Another method is to increase the multi-directional range of motion of the latch by adding a latch sliding groove to achieve the latch reverse support pre-installation function. This structure is prone to latch loosening, which poses a risk of the latch coming off and causing the hinge to malfunction. Utility Model Content

[0003] To effectively solve such practical problems, this utility model proposes an oven hinge that can simultaneously meet the locking and anti-support pre-assembly function requirements of the hinge, while also having the advantages of aesthetics, economy, and reliability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an oven hinge, comprising: a shell, a head rotatably connected to the lower end of the shell, and a buffer assembly installed inside the shell. The head is provided with a latch, which is rotatably connected to the head via a shaft. The head is provided with a limiting protrusion. The shell is provided with a first support surface. The latch rotates to simultaneously abut against the support surface and the limiting protrusion, thereby positioning the head at a first angle.

[0005] As a preferred embodiment of this utility model, the cross-section of the latch is L-shaped, one end of the latch is rotatably connected to the head to form a first connection point; the other end of the latch forms a second support surface, and when the head is at a first angle, the latch can rotate until the second support surface abuts against the first support surface.

[0006] As a preferred embodiment of this utility model, the head is in the shape of a thin sheet, and the limiting protrusion is formed by protruding outward perpendicular to the upper and lower surfaces of the head; the latch includes: an L-shaped left side plate and a right side plate, one end of the left side plate and the right side plate are connected to form the second support surface; when the latch rotates around the first connection point, the head can partially enter the gap between the left side plate and the right side plate.

[0007] As a preferred embodiment of this utility model, the lower end of the outer shell is provided with an opening groove, and one wall of the opening groove forms a first support surface.

[0008] As a preferred embodiment of this utility model, the buffer assembly includes: an inner support, a tension spring, a compression spring pin, and a compression spring; the tension spring is connected to the upper end of the outer shell, and the lower end of the tension spring is connected to the inner support;

[0009] A compression spring is fitted onto a compression spring needle, and a pulley is provided at the lower end of the compression spring needle.

[0010] In a preferred embodiment of this invention, a side surface is formed between the upper and lower surfaces of the head, and a first contact surface is formed on the side surface. During the rotation of the head relative to the outer shell, a pulley moves along the first contact surface.

[0011] As a preferred embodiment of this utility model, an arc-shaped surface is formed on the first contact surface, and when the head rotates relative to the outer shell to the closing angle, the pulley abuts against the arc-shaped surface.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a limiting protrusion on the head, and the latch rotates to simultaneously abut against the support surface and the limiting protrusion, so that the head is positioned at a first angle, forming a stable support relationship and achieving the pre-installation function of the hinge; and, through the cooperation of the pulley and the arc-shaped surface of the head, when the head rotates relative to the outer shell to the closing angle, the pulley abuts against the arc-shaped surface, so that the head and the outer shell are stably kept in the closed state.

Detailed Implementation

[0021] 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.

[0022] An oven hinge includes: a housing 100, a head 200 rotatably connected to the lower end of the housing 100, and a buffer assembly 300 installed inside the housing 100. The head 200 is provided with a latch 400, which is rotatably connected to the head 200 via a shaft. The head 200 is provided with a limiting protrusion 210.

[0023] The outer casing 100 is provided with a first support surface 101;

[0024] The latch 400 rotates to simultaneously abut against the first support surface 101 and the limiting protrusion 210, so that the head 200 is positioned at the first angle.

[0025] Specifically, the outer shell 100 is long and strip-shaped, and is formed by pressing or bending high-hardness metal, while the head 200 is thin and sheet-shaped, and is also formed by pressing high-hardness metal.

[0026] The oven hinge is installed in the oven. The outer shell 100 can be installed in the oven body, while the head 200 is installed in the oven door. Thus, as the head 200 rotates relative to the outer shell 100, the oven door rotates relative to the oven body.

[0027] Assuming the oven door and oven body are closed, the head 200 rotates relative to the outer shell 100 to the closing angle, that is... Figure 5 As shown in the angle, when the oven door and oven body are opened to their maximum, the head 200 is relative to the outer shell 100 from... Figure 5 Rotate the orientation counterclockwise until it reaches its maximum angle, which is the opening angle.

[0028] When installing the oven hinge, the head 200 needs to be rotated relative to the outer shell 100 to the first angle to facilitate installation. The first angle is a certain angle between the closing angle and the opening angle. As long as the oven hinge structure remains unchanged, this first angle will not change with the oven model.

[0029] When the head 200 rotates to the first angle, the latch 400 rotates so that it simultaneously abuts against the first support surface 101 and the limiting protrusion 210; as Figure 4 As shown, if Figure 4When the structure of the latch 400 is removed, the head 200 should rotate clockwise under the pulling force of the buffer assembly 300, that is, to close the angle rotation, the latch 400 is set. After the latch 400 is rotated to simultaneously abut against the first support surface 101 and the limiting protrusion 210, the upper end of the latch 400 abuts against the first support surface 101, and the latch 400 cannot continue to rotate clockwise. Meanwhile, the limiting protrusion 210 of the head 200 abuts against the side wall of the latch 400. Since the latch 400 cannot continue to rotate clockwise, the head 200 also cannot rotate clockwise. That is, the head 200 is positioned at the first angle relative to the outer shell 100.

[0030] Meanwhile, under the action of the buffer component 300, the buffer component 300 provides the head 200 with a clockwise rotation force, which makes the latch 400 press more firmly against the first support surface 101, forming a more stable support relationship.

[0031] Furthermore, the cross-section of the latch 400 is L-shaped, one end of the latch 400 is rotatably connected to the head 200 to form a first connection point; the other end of the latch 400 forms a second support surface 410, and when the head 200 is at a first angle, the latch 400 can rotate until the second support surface 410 abuts against the first support surface 101.

[0032] This structure of the second support surface 410 makes the latch 410 and the first support surface 101 more stable.

[0033] Furthermore, the head 200 is in the form of a thin sheet, and the limiting protrusion 210 is formed by protruding outward perpendicular to the upper and lower surfaces of the head 200; the latch 400 includes: an L-shaped left side plate and a right side plate, one end of the left side plate and the right side plate are connected to form the second support surface 410; when the latch 400 rotates around the first connection point, the head 200 can partially enter the gap between the left side plate and the right side plate;

[0034] This can be understood as the head 200 being partially clamped to the latch 400, and the upper and lower surfaces of the head 200 are provided with limiting protrusions 210 to form a more stable support.

[0035] Furthermore, the lower end of the outer casing 100 is provided with an opening groove 110, and one wall of the opening groove 110 forms a first support surface 101.

[0036] Furthermore, such as Figure 2As shown, the buffer assembly 300 includes: an inner support 310, a tension spring 320, a compression spring pin 330, and a compression spring 340; the tension spring 320 is connected to the upper end of the outer shell 100, and the lower end of the tension spring 320 is connected to the inner support 310; the compression spring 340 is sleeved on the compression spring pin 330, and a pulley 350 is provided at the lower end of the compression spring pin 330; the compression spring pin 330 is in the inner support 310, and the pulley 350 passes through a shaft, which is supported on the strip groove of the outer shell 100.

[0037] Furthermore, a side surface is formed between the upper and lower surfaces of the head 200, and a first contact surface 201 is formed on the side surface. During the rotation of the head 200 relative to the outer shell 100, the pulley 350 moves along the first contact surface 201.

[0038] Furthermore, an arc-shaped surface 2011 is formed on the first contact surface 201. When the head 200 rotates relative to the outer shell 100 to the closing angle, the pulley 350 abuts against the arc-shaped surface 2011.

[0039] like Figure 5 As shown, when the closed angle is reached, the pulley 350 abuts against the arc surface 2011, forming a reliable locking relationship and satisfying the hinge locking requirements; when the head 200 needs to rotate counterclockwise, the pulley 350 needs to overcome the obstruction of the arc surface 2011 and lift up a small distance before rolling along the arc surface 2011, and the head 200 continues to open.

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.
