It should be noted that, when the door body 2 is in a closed state, the head of the external spiral surface on the rotating shaft and the head of the spiral surface of the sliding block on the sliding block are radial end surfaces, so that the rotating shaft and the sliding block can be kept in mutual abutment, at the moment, the rotating shaft and the sliding block are only subjected to an axial spring force F1 provided by the spring assembly, at the moment, the deformation amount of the spring assembly is the maximum deformation amount in the process of opening the door from closing to the maximum opening angle, namely, the spring force F1 is the maximum spring force in the process, and the hinge does not provide a rotation moment in opening; in the opening process of the door body 2, the outer spiral surface on the rotating shaft is in sliding fit with the spiral surface of the upper sliding block of the sliding block, the sliding block moves outwards gradually along the axial direction, and the deformation amount of the spring assembly gradually becomes smaller; when the door body 2 is opened to the maximum opening angle, the outer spiral surface on the rotating shaft is meshed and locked with the spiral surface of the sliding block upper sliding block, the sliding block does not move along the axial direction any more, the deformation quantity of the spring assembly does not change any more, the moment generated by the hinge mechanism 4 is larger than the moment generated by the self weight of the door body 2, and the door body can be suspended and cannot move.

The hinge mechanism 4 can keep the door body balanced, occupies small space, does not increase the overall dimension of the device or equipment, and ensures the attractive appearance of the device.
Further, the housing 5 further includes a housing connecting portion having one end detachably connected to the device body 1 and the other end connected to the housing main portion, and the housing connecting portion is disposed on the inner cavity wall or the outer wall of the device body 1. The shell connecting part can be of a plate-shaped structure, and is particularly arranged on the outer wall of the device body 1, the shell is integrally of an L-shaped structure, the connection is more stable through the side wall support of the device body 1, and meanwhile, the hinge mechanism can be conveniently disassembled and assembled outside the device. Specifically, a plurality of bolt holes can be uniformly formed in the housing connecting portion, and the housing 5 can be detachably connected to the device body 1 by bolts.
In order to facilitate the coupling of the door body 2 and the rotating shaft, the outer end of the rotating shaft is in a square head structure, and a square head clamping groove matched with the square head structure in a clamping manner is arranged on the door body 2. That is, the rotating shaft includes a working portion with an external spiral surface (i.e., an inner end) and a square head structure (i.e., an outer end) connected to the door body 2.
In addition, it should be explained that in a hinge mechanism, a damping component may be disposed at one end of the inner cavity of the housing connection portion, and a rotation shaft for coupling with the door body 2 may be disposed at the other end.
Of course, in a preferred embodiment, in order to make the door body 2 more uniformly and stably stressed in the opening and closing process, two damping assemblies may be symmetrically disposed in the inner cavity of the housing connecting portion.
Wherein, one damping component comprises a first rotating shaft 6, a first sliding block 8 and a spring component 11, the other damping component comprises a second sliding block 9, a second rotating shaft 7 and a spring component 11, and the spiral directions of the outer spiral surfaces of the first rotating shaft 6 and the second rotating shaft 7 are opposite.
That is, the rotating shaft mechanism includes a first rotating shaft 6, a first slider 8, two spring assemblies 11, a second slider 9, and a second rotating shaft 7, which are coaxially provided in this order. The first rotating shaft 6, the first sliding block 8, the two spring assemblies 11, the second sliding block 9 and the second rotating shaft 7 are sequentially abutted end to end, particularly, two ends of each spring assembly 11 are respectively abutted against the end face of the first sliding block 8 and the end face of the second sliding block 9, a certain distance is reserved between the end face of the first sliding block 8 and the end face of the second sliding block 9, and the distance is an elastic compression area of the compression spring assemblies 11 in the door opening and closing process. Of course, the two spring assemblies 11 may be formed by one spring assembly.
The inner end of the first rotating shaft 6, the first sliding block 8, the spring assembly 11, the second sliding block 9 and the inner end of the second rotating shaft 7 are all arranged in the inner cavity of the main body part of the shell, and the outer end of the first rotating shaft 6 and the outer end of the second rotating shaft 7 are connected with the door body 2.
As shown in fig. 8-9, three protrusions with helical surfaces are uniformly arranged on the first rotating shaft 6 and the second rotating shaft 7 along the circumferential direction, and a corresponding number of protrusions with helical surfaces are also arranged on the corresponding first sliding block 8 and the corresponding second sliding block 9. The axial elastic force provided by the spring assembly 11 is transmitted to the spiral surface of the rotating shaft through the spiral surface on the sliding block, the tangential component force of the axial force at the spiral surface is divided by the door body within a certain opening angle range, so that the rotating shaft generates moment, the moment is greater than the moment generated by the weight of the door body 2, the directions of the moment and the moment are opposite, and the door body can be suspended and fixed.
It should be noted that the moment of the door 2 gradually decreases as the door opening angle increases.
In the opening/closing process of the door body, the door body 2 drives the first rotating shaft 6 and the second rotating shaft 7 to rotate together, meanwhile, the first sliding block 8 and the second sliding block 9 move outwards/inwards along the axial direction due to the rotation movement, the spring assembly 11 is compressed all the time, and in a specific opening angle range, the radial supporting force generated by the axial elastic force generated by the spring assembly 11 after extruding the spiral surface just can overcome the gravity of the door body, so that the door body is kept stable.
As shown in fig. 2, the device body 1 is provided with two hinge mechanisms 4, in practical application, the specific number of the hinge mechanisms 4 is set according to the length of the door body 2, and at least one hinge mechanism 4 is provided. The hinge mechanism 4 in the scheme is an independent unit structure, can be directly installed on a device or equipment, and does not need to be provided with an external decoration piece. The hinge mechanism 4 is simple to assemble and does not require riveting or screwing.
In a preferred embodiment, the rotating shaft mechanism further comprises a damper 10 disposed between the first slider 8 and the second slider 9 and located at an inner ring of the spring assembly 11, and a spring damper may be particularly used. The damper 10 operates on the principle that a reaction force, called a damping force, for damping an external force is generated to delay the damping of a motion state.
In order to facilitate installation of the damper 10, effective positioning and shaking prevention are performed, a boss is arranged on the inner end face of the second slider 9, and a counter bore used for being embedded into one end of the damper 10 is formed in the boss. The damper 10 can pass through the through hole 19 in the spacer structure 20. The damper 10 reciprocates axially together with the second slider 9.
Further, the length of the damper 10 is shorter than that of the spring assembly 11 so as to perform a damping function when the door body 2 is opened to a small door opening angle.
The principle in the scheme is that during the closing process of the door body 2, the external spiral surface of the first rotating shaft 6 presses the spiral surface of the first sliding block 8 to enable the first sliding block 8 to move inwards along the axial direction of the shell 5, and the external spiral surface of the second rotating shaft 7 presses the spiral surface of the second sliding block 9 to enable the second sliding block 9 to move inwards along the axial direction of the shell 5. When the door body 2 moves to a small opening and closing angle, the end part of the damper 10 is extruded by the first sliding block 8 and the second sliding block 9 to generate damping force.
On the whole, like a horizontal refrigerator, the door body 2 is easy to be influenced by self gravity to be automatically closed after being opened, and when the opening angle is small, the closing speed is too fast, and hands are easy to clamp. In the hinge mechanism of this scheme, the produced elasticity of spring unit produces the radial force towards the door opening direction on the spiral cambered surface for overcome the gravity of the door body in-process door that opens and shuts, and change along with the door opening and shutting angle, spring unit's holding power also correspondingly changes, in addition, cooperate attenuator 10 again and play the damping effect when less opening and shutting angle, thereby can make the door remain balanced all the time, the degree of opening and shutting of the door body and the free stable performance that keeps have promoted greatly, thereby promote the hinge performance, increase of service life.
According to the scheme, the design that the spring assembly 11 and the damper 10 are combined is adopted, and in the process of opening and closing the door, when the opening angle of the door is large, the spring assembly 11 plays a main role, so that the phenomenon that the door is opened to generate certain impact force due to overlarge elastic force is avoided; when the door opening angle is smaller, the spring assembly 11 and the damper 10 act together, and the problem that the door cannot be stable due to the fact that the angle is too small and the force is insufficient is avoided.
Specifically, the external spiral surface of the first rotating shaft 6 is an elongated spiral surface, and the slider spiral surface of the first slider 8 is an elongated slider spiral surface. During the closing process of the door body 2, the external spiral surface of the first rotating shaft 6 presses the spiral surface of the first sliding block 8 to enable the first sliding block 8 to move inwards along the axial direction of the shell 5, and the external spiral surface of the second rotating shaft 7 presses the spiral surface of the second sliding block 9 to enable the second sliding block 9 to move inwards along the axial direction of the shell 5. When the door body 2 moves to a smaller opening and closing angle, the spiral surface of the second rotating shaft 7 is not meshed with the spiral surface 40 of the second sliding block 9, the damper 10 does not move axially, and in the position, the end surface of the first sliding block 8 contacts the pressing block 41 on the damper 10; the door body 2 continues to rotate downwards, and the lengthened spiral surface of the first rotating shaft 6 presses the lengthened spiral surface of the second sliding block 8 to enable the first sliding block 8 to continue to move inwards; at a certain angle, the damper 10 generates the maximum resistance, and the downward rotation speed of the door body 2 becomes slow. Until the lengthened spiral surface of the first rotating shaft 6 is not meshed with the lengthened spiral surface of the second sliding block 8, the second sliding block 8 does not move along the axial direction, and the door body 2 freely rotates downwards until the door body is completely closed.
The inner cavity of the main body part of the shell provided by the scheme comprises a first cavity 14 and a second cavity 15, wherein the first cavity 14 and the second cavity 15 are separated by a spacing structure 20, and a through hole 19 is formed between the spacing structures 20.

A first spring and a second spring are compressed between the first sliding block 8 and the second sliding block 9, and flat washers 12 are arranged at two ends of the first spring and two ends of the second spring. The flat washer 12 serves to prevent the spring assembly 11 from wearing the plastic member during the opening and closing of the door, and also to improve the pressure-bearing capacity of the plastic member.

The guide rib 18 may be one, or may be a plurality of ribs uniformly arranged along the circumferential direction of the inner cavity of the housing main body portion. The number of grooves corresponds one-to-one according to the number and position of the guide ribs 18.
In particular, the positions of the guiding ribs in the first chamber 14 and the second chamber 15 can be set to different positions to prevent the sliders and the rotating shaft at the two ends from being misplaced.
Furthermore, both ends of the inner cavity of the main body part of the shell are sequentially provided with a guide boss 16 for guiding and a ring groove 17 for axially positioning the first rotating shaft 6 and the second rotating shaft 7 from outside to inside, and the guide boss 16 is arranged on the extension line of the guide rib 18 and is consistent with the width and height of the guide rib 18. The inner wall of the housing 5 may be provided with a plurality of unequal guide ribs 18, the guide ribs 18 extending along the housing axis. The effect of direction muscle is to leading to the slider, prevents that the slider from rotating.

Correspondingly, the first rotating shaft 6 and the second rotating shaft 7 are sequentially provided with an annular groove in concave-convex fit with the guide boss 16 and a non-through groove in concave-convex fit with the annular groove 17 along the direction from the outer end to the inner end.
