[0002] From the known literature, we know that a hinge is a connecting device that can fix two objects, and it can allow the two connected objects to rotate or swing along a fixed axis. Moreover, according to the function and structure of the hinge, it can be divided into many types, such as flat hinges, horizontal hinges, notch hinges, leaf spring hinges, etc.
[0003] Among them, for the horizontal hinge, its definition means that the plane where the hinge is located is perpendicular to the hinge position. The horizontal hinge is mainly composed of a hinge body, a hinge shaft, a hinge pin and a hinge pin rod. As for the use of the horizontal hinge, it can be used in household appliances such as refrigerators, disinfection cabinets, and ovens, because these appliances are equipped with door bodies and cabinet bodies, and the door bodies and cabinet bodies are generally connected by horizontal hinges to achieve opening and closing.
[0004] However, the horizontal hinges in the prior art generally have a complex structure and a relatively high manufacturing cost. Moreover, the load-bearing range of the horizontal hinge is generally around 10 kg, while some household appliances use drop-down door bodies, such as integrated stoves, whose door bodies weigh more than 10 kg, resulting in some existing horizontal hinges no longer meeting usage requirements.

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] Embodiment 1:
[0027] like Figures 1 to 6 As shown, an improved horizontal hinge described in the utility model comprises a shell 1, which is hollow and U-shaped, and in the hollow shell 1, elastic elements 2, conductive elements 3 and output elements 4 are arranged in sequence along the vertical direction, wherein the elastic element 2 is connected to the conductive element 3, and the output element 4 is connected to an end of the conductive element 3 away from the elastic element 2, and a condensation structure 5 is provided on the output element 4;
[0028] Furthermore, the elastic element 2 includes a tension spring 21 , a tension spring rivet hole 22 is opened at the top of the shell 1 , a tension spring rivet 23 is fixed in the tension spring rivet hole 22 , and one end of the tension spring 21 close to the top of the shell 1 is fixed to the tension spring rivet 23 through a fixing sleeve 24 .
[0029] Further, the conducting element 3 comprises an inner bracket 31, on which a No. 1 guide hole 32 and a No. 2 guide hole 33 are formed, and a No. 1 guide groove 34 is formed near the No. 1 guide hole 32 on the outer wall of the housing 1, and the number of the No. 1 guide grooves 34 is two, and the No. 1 guide hole 32 and the No. 1 guide groove 34 are connected by a No. 1 guide rivet 35, and the No. 1 guide rivet 35 is slidably connected to the No. 1 guide groove 34; the end of the tension spring 21 away from the tension spring rivet 23 is fixedly connected to the No. 1 guide rivet 35 through a fixing sleeve 24;
[0030] A No. 2 guide groove 36 is provided on the outer wall of the housing 1 near the No. 2 guide hole 33 . The number of the No. 2 guide grooves 36 is two. The No. 2 guide hole 33 and the No. 2 guide grooves 36 are connected by a No. 2 guide rivet 37 , and the No. 2 guide rivet 37 and the No. 2 guide groove 36 are slidably connected by a guide wheel 38 .
[0031] Furthermore, the output element 4 includes a head 40, a first flower wheel hole 41 is provided on the head 40, a second flower wheel hole 42 is provided at the bottom of the housing 1, the first flower wheel hole 41 and the second flower wheel hole 42 are connected via a flower wheel 43 and a pivot rivet 44, and the flower wheel 43 is sleeved on the surface of the pivot rivet 44, and the flower wheel 43 is rotatably connected to the first flower wheel hole 41.
[0032] Furthermore, the condensation structure 5 includes a condensation hole 51, and a connecting hole 52 is opened at one end of the inner bracket 31 away from the No. 2 guide hole 33. The condensation hole 51 and the connecting hole 52 are rotatably connected by a roller rivet 53, and a roller 54 is sleeved on the roller rivet 53, and the roller 54 is located in the condensation hole 51; it is used to reduce the friction between the inner bracket 31 and the head 40 when rotating.
[0033] Specifically, when the horizontal hinge is in use, the output element 4 inputs an external torque, and the elastic element 2 outputs a restoring torque, which is transferred to the output element 4 after transition through the conductive element 3 to offset the gravitational potential energy; the output element 4 realizes a closed form, and the elastic element 2 and the locking structure mutation characteristics realize force enhancement to meet the locking state;
[0034] Furthermore, when the horizontal hinge is applied in practice, such as in a microwave oven or an integrated stove, the housing 1 is connected to the cabinet of the microwave oven or the integrated stove, and the head 40 is connected to the cabinet door of the microwave oven or the integrated stove. Figure 4 and 5As shown, the angle between the head 40 and the shell 1 becomes larger, and the tension spring 21 is stretched at this time, the No. 1 guide rivet 35 moves downward in the No. 1 guide groove 34, and the No. 2 guide rivet 37 moves downward in the No. 2 guide groove 36. Since a No. 1 flower wheel hole 41 is provided on the head 40, and a No. 2 flower wheel hole 42 is provided at the bottom of the shell 1, the No. 1 flower wheel hole 41 and the No. 2 flower wheel hole 42 are connected by a flower wheel 43, and the flower wheel 43 is rotatably connected with the No. 2 flower wheel hole 42. At this time, the head 40 can rotate relative to the inner bracket 31, so that the roller rivet 53 moves to the position A in the shrinkage hole 51 to achieve locking of the head 40. At this time, the horizontal hinge is in the open state, that is, the cabinet door is in the open state. At this time, the horizontal hinge realizes high load-bearing capacity for the cabinet door, that is, the external torque is input to the output element 4, and the elastic element 2 outputs the restoring torque, which is transferred to the output element 4 after transition through the conduction element 3 to offset the gravitational potential energy.
[0035] When closing the cabinet door, Figure 2 and 3 As shown, the head 40 is moved in the reverse direction, and the angle between the head 40 and the shell 1 gradually becomes smaller. At this time, the tension spring 21 gradually returns to its original state, and the No. 1 guide rivet 35 moves upward in the No. 1 guide groove 34, and the No. 2 guide rivet 37 moves upward in the No. 2 guide groove 36. Since a No. 1 flower wheel hole 41 is provided on the head 40, and a No. 2 flower wheel hole 42 is provided at the bottom of the shell 1, the No. 1 flower wheel hole 41 and the No. 2 flower wheel hole 42 are connected by a flower wheel 43, and the flower wheel 43 is rotatably connected to the No. 2 flower wheel hole 42. At this time, the head 40 can rotate relative to the inner bracket 31, so that the roller rivet 53 moves to the position B in the shrinkage hole 51. At this time, the horizontal hinge is in a closed state, that is, the cabinet door is in a closed state.
[0036] Embodiment 2 is different from Embodiment 1 in that:
[0037] An inverted U-shaped groove 6 is provided at the bottom of the housing 1 at the head 40 to prevent the head 40 from interfering with the housing 1 when rotating.
[0038] Furthermore, the inner walls of the No. 1 guide groove 34 and the No. 2 guide groove 36 are both smoothed.
[0039] Furthermore, the surfaces of the shell 1 and the head 40 are both subjected to anti-corrosion treatment.
[0040] Specifically, because an inverted U-shaped groove 6 is provided at the bottom of the shell 1 at the head 40, when the head 40 rotates relative to the inner bracket 31, the shell 1 will not interfere with it, preventing the head 40 from being unable to rotate relative to the inner bracket 31. At the same time, the inner walls of the No. 1 guide groove 34 and the No. 2 guide groove 36 are selected to be smoothed, such as polished, etc., so as to reduce the friction of the No. 1 guide rivet 35 when it moves in the No. 1 guide groove 34. At the same time, although the No. 2 guide rivet 37 is slidably connected to the No. 2 guide groove 36 by the guide wheel 38, polishing the inner wall of the No. 2 guide groove 36 can further reduce the friction of the No. 2 guide rivet 37 when it moves in the No. 2 guide groove 36, thereby improving the actual use effect of the present application. Moreover, since the general use environment of the present application is a microwave oven and an integrated stove, and it is often in contact with water vapor, in order to ensure the service life of the present application, the shell 1 and the head 40 need to be subjected to anti-corrosion treatment, such as electroplating, spraying anti-corrosion coating, etc., thereby improving the service life of the present application. Of course, other components of the present application can also be subjected to anti-corrosion treatment.
