Technical Field
[0001] This utility model relates to the field of oven technology, and more specifically, to a detachable oven door hinge. Background Technology
[0002] An oven is a sealed appliance used to bake food or dry products. It is divided into household ovens and industrial ovens. Ovens usually have a set of rotating doors connected by hinges so that the oven can be opened or closed.
[0003] Chinese patent CN213449926U discloses a detachable oven door hinge, including an outer box and an inner box. The inner box is fixed to the inner wall of the outer box, and symmetrically distributed bottom plates are provided on both outer walls of the inner box near the edges. A protective plate is provided on one outer wall of the bottom plate, and a fixing frame is provided on both outer walls of the inner box near the middle. The hinge can generate a reverse torque when the oven door is opened by the elastic force of its internal return spring. During the closing process, the torque can offset the weight of the oven door itself, so that the oven door and the oven body are tightly fitted. However, the initial compression degree of the internal spring cannot be adjusted, so the torque value generated by the spring on the oven door cannot be flexibly adjusted. Since the weight of oven doors varies greatly from oven to oven, when the hinge is installed on different ovens, the torque on the oven door may be too large to open smoothly, or the torque on the oven door may be too small to close tightly with the oven body. Therefore, the hinge can only be installed on oven doors of a fixed weight, and its applicability is poor. Utility Model Content
[0004] This invention provides a detachable oven door hinge, which solves the technical problem in the prior art that the initial compression degree of the internal spring of the hinge cannot be adjusted, making it unsuitable for installation on oven doors of different weights and resulting in poor applicability.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A detachable oven door hinge includes a hinge body. A set of rotating shafts is rotatably connected inside the hinge body. One end of each rotating shaft extends outward from the hinge body and is fixedly connected to a connecting frame. A set of sliders is slidably connected inside the hinge body. An abutment plate is located at the rear end of each slider inside the hinge body. A spring connects the slider and the abutment plate. A rack is fixedly connected to the front end of each slider. A gear is sleeved on the surface of each rotating shaft, and the rack meshes with the gear. An adjustment component acting on the abutment plate is provided on the hinge body. The adjustment component allows adjustment of the front-rear position of the abutment plate and fixes it within the hinge body.
[0007] Furthermore, screw holes are provided on the outer wall of the hinge body and on the slider.
[0008] Furthermore, the adjustment assembly includes a screw sleeve disposed at the rear end of the hinge body and a screw rod threadedly connected inside the screw sleeve. One end of the screw rod extends into the interior of the hinge body and is rotatably connected to the abutment plate, while the other end of the screw rod extends out of the outside of the hinge body and is provided with a cross-shaped cap.
[0009] Furthermore, a protective groove is provided at the rear end of the hinge body, which covers the cross-shaped cap at the end of the screw inside.
[0010] Furthermore, a limiting pin is provided on the slider, and a limiting slot is opened on the outer wall of the hinge body, with the limiting pin extending into the limiting slot.
[0011] Furthermore, the hinge body is made of aluminum alloy.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the adjustment component can control the movement of the contact plate forward or backward and fix the contact plate, thereby adjusting the front and back position of the contact plate. Therefore, when the oven door is fixed, the user can adjust the distance between the contact plate and the slider by controlling the front and back position of the contact plate, and thus adjust the initial compression degree of the spring between the slider and the contact plate. Therefore, when the hinge body is installed on different ovens, the user can flexibly adjust the elastic force generated by the spring on the slider when opening the oven door by adjusting the initial compression degree of the spring, thereby adjusting the torque on the oven door. This allows the hinge to adapt to oven doors of different weights, effectively improving its applicability. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] Please see Figure 1-4A detachable oven door hinge includes a hinge body 1. A set of rotating shafts 2 are rotatably connected inside the hinge body 1. One end of the rotating shaft 2 extends outward from the hinge body 1 and is fixedly connected to a connecting bracket 3. Screw holes 4 are provided on the outer wall of the hinge body 1. By using screws passing through the screw holes 4, the hinge body 1 can be fixedly installed on the side wall of the oven. The connecting bracket 3 also has screw holes 4, which, with the help of screws, can be fixedly connected to the side wall of the oven door. Since the connecting bracket 3 can rotate relative to the hinge body 1, when the two are connected to the oven door and oven body respectively, the oven door can rotate relative to the oven body. A set of sliders 5 are slidably connected inside the hinge body 1. An abutment plate 6 is provided at the rear end of the sliders 5 inside the hinge body 1. A spring 7 connects between the sliders 5 and the abutment plate 6. A rack 8 is fixedly connected to the front end of the sliders 5. The surface of the rotating shaft 2 is sleeved with… There is a gear 9, and a rack 8 meshes with the gear 9. When the user turns to open the oven door, the connecting frame 3 and the slider 5 rotate. At this time, the connecting frame 3 drives the rotating shaft 2 to rotate, and the gear 9 drives the rack 8 it meshes with to move backward. At this time, the slider 5 moves backward under the drive of the rack 8 and moves closer to the abutment plate 6, so that the spring 7 between the slider 5 and the abutment plate 6 is compressed. The spring 7 will generate a forward elastic force on the slider 5. Since this elastic force can prevent the slider 5 from moving backward and approaching the abutment plate 6, after the oven door is opened, the oven door can always be subjected to a torque in the direction of closing the oven body. When the oven door is closed, since this torque can offset the weight of the oven door, the oven door can be closed with less effort, and the oven door can be tightly pressed against the oven body when closed, ensuring that the oven door is sealed to the oven body.
[0022] When the oven door is opened, the elastic force generated by the spring 7 on the slider 5 causes the oven door to experience torque, which counteracts the weight of the oven door. Therefore, the user can close the oven door with less effort. Under the action of torque, the oven door can fit tightly against the oven body when closed, thus sealing the oven body. The hinge body 1 is equipped with an adjustment component that acts on the abutment plate 6. The user can adjust the front and back position of the abutment plate 6 by adjusting the component and fix the abutment plate 6 in the hinge body 1. Thus, the front and back position of the abutment plate 6 can be adjusted. Therefore, when the oven door is fixed, the user can adjust the distance between the abutment plate 6 and the slider 5 by controlling the front and back position of the abutment plate 6, thereby adjusting the initial compression degree of the spring 7 between the slider 5 and the abutment plate 6. When the hinge body 1 is installed on different ovens, the user can flexibly adjust the elastic force generated by the spring 7 on the slider 5 when opening the oven door by adjusting the initial compression degree of the spring 7, thereby adjusting the torque on the oven door. This allows the hinge to adapt to oven doors of different weights, effectively improving its applicability.
[0023] For further details, please refer to Figure 1-4The adjustment assembly includes a screw sleeve 10 located at the rear end of the hinge body 1 and a screw 11 threadedly connected inside the screw sleeve 10. One end of the screw 11 extends into the hinge body 1 and is rotatably connected to the abutment plate 6. The other end of the screw 11 extends out of the hinge body 1 and is provided with a cross-hole cap 12. The user can control the screw 11 to rotate by aligning a screwdriver with the cross-hole cap 12. During the rotation, the screw 11 can move towards the outside or inside of the hinge body 1 under the driving action of the screw sleeve 10. Thus, one end of the screw 11 will control the abutment plate 6 to move back and forth inside the hinge body 1. When the screw 11 is stopped from rotating, the screw sleeve 10 can lock the screw 11, so that the abutment plate 6 can be fixed in the adjusted position.
[0024] For further details, please refer to Figure 1-4 The rear end of the hinge body 1 is provided with a protective groove 13. The protective groove 13 covers the cross hole cap 12 at the end of the screw 11 inside, which can prevent the user from accidentally touching the cross hole cap 12 during the use of the oven, causing the screw 11 to rotate, thereby avoiding displacement of the contact plate 6 and causing a change in the initial compression of the spring 7.
[0025] For further details, please refer to Figure 1-4 The slider 5 is equipped with a limiting pin 14, and a limiting slot 15 is opened on the outer wall of the hinge body 1. The limiting pin 14 extends into the limiting slot 15. When the door is opened and closed, the slider 5 will drive the limiting pin 14 to slide along the inside of the limiting slot 15 during the movement. The limiting pin 14 and the limiting slot 15 can guide the movement of the slider 5, so that it can always slide straight inside the hinge body 1 without deviating. The limiting pin 14 and the limiting slot 15 can limit the movement stroke of the slider 5. When the door is rotated and opened to 90° with the box body, the limiting pin 14 will slide to the end position of the limiting slot 15. At this time, the slider 5 can no longer move backward, thus limiting the door from continuing to rotate, so that the door will not hit the table below due to the excessive opening angle.
[0026] Furthermore, the hinge body 1 is made of aluminum alloy, which is lightweight and high-strength, and is not easily deformed or damaged during use.
[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
