Note that, the arrangement of the plurality of storage compartments 20 of the refrigerator is not limited to the above exemplary description.
The front end of the storage chamber 20 is formed with a taking-out opening to put food into the storage chamber 20 or take out food from the storage chamber 20; a rotatable door 30 is provided on the case 10 to open or close the access opening of the storage compartment 20. Specifically, the door 30 is rotatably connected to the case 10 by a hinge at an upper portion and a hinge at a lower portion.

The positioning groove 6 is arranged in the direction from the first guide strip 8 to the second guide strip 9. In addition, the first guide strip 8 and the second guide strip 9 both extend in the direction from the door front wall 31 to the door rear wall 33, and the first guide strip 8 is located on the side of the second guide strip 9 away from the door side wall 32; i.e. the guide groove 7 extends in a direction from the door front wall 31 to the door rear wall 33.
It should be noted that, the guide groove 7 is not limited to the above-defined form defined by the first guide bar 8 and the second guide bar 9, and may be formed with a concave guide groove 7 directly at the end of the door body, the lux triangle 5 is matched with two opposite groove walls of the guide groove 7, and the positioning groove 6 is formed on the groove bottom of the guide groove 7.
Wherein the hinge shaft 4 is adapted to the positioning slot 6, and the triangular lux block 5 is adapted to the guide slot 7; wherein the side length of the regular triangle of the triangular block 5 is a, and the width of the guide groove 7 is equal to the side length of the regular triangle of the triangular block 5, namely, the width of the guide groove 7 is a. The triangular block 5 is always tangential to the first and second guide bars 8, 9 when the triangular block 5 moves relative to the guide groove 7. During the rotation of the door body 30 to be opened or closed, the hinge shaft 4 moves relative to the positioning slot 6, and the lux triangular block 5 moves relative to the guide slot 7.
Here, the embodiment of the present application will be described by taking the hinge shaft 4 and the triangular block 5 as examples, and the positioning slot 6, the first guide bar 8, and the second guide bar 9 are provided on the door body 30. The arrangement of the hinge shaft 4, the lux triangular block 5, the positioning slot 6, the first guide bar 8, and the second guide bar 9 is not limited to the above arrangement on the hinge or the door 30. The hinge shaft 4 is matched with the positioning slot 6, one of the hinge shafts is arranged on the door body 30, and the other hinge shaft is arranged on the hinge; the triangular block 5 is matched with the guide slot 7, the triangular block 5 is fixed with the hinge shaft 4, the positioning slot 6 is positioned in the guide slot 7, the position of the triangular block 5 is consistent with the position of the hinge shaft 4, and the position of the positioning slot 6 is consistent with the position of the guide slot 7. The above positions are different, but the principle is the same and will not be described in detail.
The hinge includes a hinge plate 40 fixedly connected with the case 10, the hinge plate 40 including: a connection portion 401 connected to the case 10, and a plate-like extension portion 402 extending forward from the connection portion 401 and having a horizontal plane. The connection portion 401 may be fastened to the top wall of the case 10 by fasteners such as screws, pins, and bolts.
Specifically, the hinge at the upper end of the door body 30 includes a hinge plate 40 connected to the upper end of the case body 10, and the hinge shaft 4 and the lux triangular block 5 are fixedly connected to the hinge plate 40. The hinge plate 40, the hinge shaft 4, and the lux triangle 5 may be integrally formed; but, unlike this, the hinge plate 41, the hinge shaft 4 and the lux triangle 5 may be separately provided and assembled with each other. Wherein a hinge shaft 4 and a lux triangle 5 are formed on the extension 402, the hinge shaft 4 extending vertically downward.
The hinge at the lower end of the door 30 is connected to the front end surface of the case 10 at a connecting portion 401. The hinge shaft 4 and the lux triangle 5 are on the hinge plate 40, and the hinge shaft 4 extends upward.
The door body 30 is provided at both upper and lower ends thereof with a positioning groove 6 and a guide groove 7 corresponding to the position of the hinge plate 40. And the two positioning grooves 6 at the upper end and the lower end of the door body 30 correspond to each other in the vertical direction, and the two guiding grooves 7 correspond to each other in the vertical direction. Namely, in the projection of the plane of the top wall of the box body 10, the projections of the central lines of the two positioning grooves 6 at the upper end and the lower end of the door body 30 are completely overlapped, and the projections of the central lines of the two guide grooves 7 at the upper end and the lower end of the door body 30 are completely overlapped.
In this embodiment, with continued reference to fig. 2, a plane on the side surface (first body side wall) of the cabinet 10 adjacent to the hinge plate 40 is defined as a reference plane M, the refrigerator is accommodated in the cabinet 100, and the side of the reference plane M adjacent to the cabinet 100 is the outside, and the opposite side thereof adjacent to the storage compartment 20 is the inside. When the refrigerator is placed in the cabinet 100 for use, in order to prevent factors such as uneven ground of a user and deformation of the cabinet 100, the cabinet 100 is sized such that a distance α=5 mm from a side surface of the refrigerator (i.e., the first body sidewall is the reference plane M). In order to ensure that the door 30 of the refrigerator is normally opened, the side edges K of the door 30 cannot protrude too much beyond the side (reference plane M) of the cabinet 10 during rotation of the door 30, so as to prevent the door 30 from being abnormally opened due to collision of the side edges K with the cabinet 100.
To meet the above requirements, the door 30 needs to be able to move inward during rotation so that the side edge K does not protrude too far beyond the side (reference plane M) of the case 10. Taking the case that the link plate 40 is disposed on the right side of the door body 30 (in this example, the left side wall of the case 10 is the first body side wall), the inner side is the left side, that is, the door body 30 needs to be able to move to the left side; taking the hinge plate 40 as an example on the door body 30, the inner side is the right side, i.e., the door body 30 needs to be movable to the right side.
In this embodiment, the positioning groove 6 and the guiding groove 7 are respectively linear; that is, the positioning groove 6 and the guide groove 7 are each constituted by only a segment of a linear groove. The hinge shaft 4 is matched with the positioning slot 6, and the triangular luxer 5 is matched with the guide slot 7. The center trajectory of the positioning groove 6 is denoted as a trajectory S. The positioning groove 6 is defined by a shape formed by a section of linear groove, and the track line S is a straight line. Wherein the trajectory line S extends in a straight line from a side far from the door sidewall 32 to a side close to the door sidewall 32 so that the door body 30 can be moved in an inward (close to the second body sidewall) direction by a distance while rotating, thereby avoiding interference with the cabinet 100 when the door body 30 is opened.
Because of the relative motion relationship between the positioning slot 6 and the hinge shaft 4, and between the guide slot 7 and the lux triangle 5, if the door body 30 uses the positioning slot 6 and the guide slot 7 as stationary references during the opening process, the movement of the hinge shaft 4 in the positioning slot 6 corresponds to the movement of the lux triangle 5 in the guide slot 7. For convenience of description, the present application uses the positioning slot 6 and the guide slot 7 as references, and the hinge shaft 4 and the triangular block 5 are described in a manner of moving relative to the references.
In addition, in the present embodiment, the central axis of the hinge shaft 4 is denoted as a positioning central axis P, and the center point of the triangular block 5 is denoted as a guiding center point O; the three vertexes of the triangular block 5 are sequentially marked as a first vertex A, a second vertex B and a third vertex C; the second vertex B is located on a side of the first vertex C remote from the first body sidewall. The three sides of the triangular block 5 are denoted as leWherein/>Is arranged opposite to the third vertex C, the first vertex A and the second vertex B in sequence. Wherein/>The center of (a) is denoted as the first center point A m,/>The center of (a) is denoted as a second center point B m,/>Is denoted as third center point C m. The hinge shaft 4 is arranged at one vertex angle of the triangular Lerlow block 5; in this embodiment, the hinge shaft 4 is disposed at the vertex angle where the triangular block 5 and the first vertex a are located. The configurable positioning center axis P is positioned on the line segment OA; i.e., A, P, O are located on the same line segment; in this embodiment, the length of the line segment OP is greater than the length of the line segment AP. The line segment OP is denoted as an axis line segment OP.
The luxuriant triangular block 5 is fixed on the box body 10, and the first vertex A, the third vertex C and the second vertex B are sequentially far away from the box body 10; that is, the distances between the first vertex a, the third vertex C, and the second vertex B and the front end surface of the casing 10 increase in order. Namely, the hinge shaft 4 is arranged at the vertex angle of the first vertex A of the Lo triangle 5 closest to the box body 10, so that the inward moving angle range of the door body 30 in the rotating process is effectively increased, the door body 30 can keep the inward moving trend in the rotating process, the distance that the side edge K of the door body 30 exceeds the side wall of the first body is limited, and the interference between the side edge K and the cabinet 100 is avoided.
In addition, in the present embodiment, the third vertex C is located on a side of the first vertex a and the second vertex B near the first body sidewall. The hinge shaft 4 is disposed at the vertex angle of the lux triangle block 5 closest to the first vertex a of the box 10, so as to effectively ensure that the door 30 has a tendency of moving inwards during rotation when the door 30 rotates relative to the lux triangle block 5. The line segment AB may be disposed parallel to the first body sidewall (the reference plane M), so that the third vertex C is a point of the lux triangle 5 closest to the first body sidewall, which effectively increases the angular range of inward movement during the rotation of the door body 30, and enables the door body 30 to maintain a tendency of inward movement during the rotation.
As shown in fig. 5-19, the movement of the hinge shaft 4 along the positioning slot 6 is equivalent to the movement of the positioning center axis P along the trajectory S. In the present embodiment, the hinge plate 40 is fixedly connected with the triangular block 5, and one of the opposite sides of the hinge plate 40 is connected with the triangular block 5Intersecting, the other side intersects with the triangular block 5 of Lerlo/>And (5) intersecting. Le triangular block 5/>Or/and/>The movement of the triangular block 5 relative to the guide groove 7 is equivalent to Yu Leluo to the movement of the triangular block 5 relative to the guide groove 7 and also to the movement of the case 10 relative to the door 30. Similarly, the movement of the axis line OP relative to the guide groove 7 is equivalent to the movement of the triangular block 5 relative to the guide groove 7 Yu Leluo, and is also equivalent to the movement of the case 10 relative to the door 30; so that the door 30 can be moved inward (in a direction approaching the second body sidewall) by a distance while rotating, thereby avoiding interference with the cabinet 100 when the door 30 is opened.
In the following description, for convenience of explanation, the movement of the positioning center axis P along the trajectory S is selected to represent the movement of the hinge shaft 4 along the positioning slot 6, and the movement of the axis line OP relative to the guide slot 7 represents the movement of the triangular block 5 relative to the guide slot 7.
As shown in fig. 5-19, the trajectory S includes a first positioning endpoint P 0 distal from the door sidewall 32 and a second positioning endpoint P e proximal to the door sidewall 32; the second positioning end point P e is located on a side of the first positioning end point P 0 near the door sidewall 32, and the track line S extends from the first positioning end point P 0 to the second positioning end point P e along a straight line toward the side near the door sidewall 32.
In this embodiment, the distance between the trajectory S and the door front wall 31 is denoted as D 1, and the distance between the trajectory S and the door rear wall 33 is denoted as D 2; wherein D 1＞D2; that is, the trajectory line S is closer to the door rear wall 33 than to the door front wall 31. Settable, D 1：D2 ε [1/3,1 ], when a user opens the door 30, the external force applied to the door 30 mainly acts on one side of the door 30 close to the door front wall 31 and far from the door side wall 32; the positioning slot 6 is close to the door rear wall 33 relative to the door front wall 31, so that the hinge shaft 4 is positioned at a position close to the door rear wall 33 and close to the door side wall 32 when the door body 30 is opened, and the rotation and movement fluency and stability of the door body 30 can be ensured; while also ensuring the strength of the door body 30 and the positioning groove 6.

In the process that the door body 30 is opened to a maximum angle G max from a closed state, the hinge shaft 4 moves relative to the positioning slot 6, and the triangular Lerlo block 5 moves relative to the guide slot 7; the following describes the door 30 rotation opening process in detail:
As shown in fig. 16, in the process of rotating the door body 30 from the closed state to G 2, the door body 30 is opened from 0 ° to G 2 through G 1. In this process, the center axis of the hinge shaft 4 (positioning center axis P) is moved by the first positioning end point P 0 along the trajectory S in a direction approaching the door sidewall 32; specifically, the center axis of the hinge shaft 4 (positioning center axis P) is moved from the first positioning end point P 0 to the second displacement point P 2 along the trajectory S through the first displacement point P 1. Before the opening angle of the door body 30 does not reach G 2 Excluding interval end point angle G 2), lux triangle 5/>Always cooperate with the first guide strip 8 and the third vertex C of the lux triangle 5 always cooperates with the second guide strip 9. When the door body 30 is opened at an angle G 2, the second vertex B of the triangular Lerlow block 5 is matched with the first guide strip 8; the third vertex C of the lux triangle 5 cooperates with the second guide strip 9.
In the opening process, the positioning groove 6 and the guide groove 7 are used as reference objects, and when the door body 30 is opened from 0 degrees to G 1, the axis line segment OP rotates clockwise from O 0P0 and moves outwards to O 1P1; when the door 30 is opened from G 1 to G 2, the axis OP rotates clockwise from O 1P1 and moves outward to O 2P2. Since the positioning groove 6 and the guiding groove 7 are arranged on the door body 30, the axis line segment OP represents the movement of the lux triangle block 5 arranged on the box body 10; the following is obtained: with the door body 30 as a reference, the lock body 30 keeps rotating clockwise and moving outwards relative to the door body 30 in the whole process from the closed state to the G 2. According to the relativity of the movement, the door body 30 (i.e. the positioning groove 6 and the guide groove 7) rotates anticlockwise and moves inwards relative to the box body 10 in the whole process of opening the door body 30 from the closed state to the G 2 by taking the box body 10 as a reference object (i.e. taking the Lerlow triangle 5 as the reference object). That is, the door 30 is rotated counterclockwise and moved inward with respect to the cabinet 10 throughout the process of the door 30 being rotated to be opened from the closed state to G 2; i.e., the door body 30 is opened while being moved inward by a certain distance.
Specifically, as shown in fig. 17, in the process of opening the door body 30 by G 2 to G 4, the door body 30 is opened by G 2 to G 4 through G 3. In this process, the center axis of the hinge shaft 4 (positioning center axis P) is moved by the second displacement point P 2 along the trajectory S in a direction approaching the door sidewall 32; specifically, the center axis of the hinge shaft 4 (positioning center axis P) moves from the second displacement point P 2 to the second positioning end point P e along the track S through the third displacement point P 3. In the process that the door body 30 is rotated and opened from G 2 to G 4 Excluding interval end point angles G 2 and G 4), the second vertex B of the lux triangle 5 always mates with the first guide bar 8, lux triangle 5/>Is always engaged with the second guide strip 9. When the door body 30 is opened at an angle G 4, the second vertex B of the triangular Lerlow block 5 is matched with the first guide strip 8; the first apex a of the triangular block 5 cooperates with the second guide strip 9.
In the opening process, the positioning groove 6 and the guide groove 7 are used as reference objects, and when the door body 30 is opened from G 2 to G 3, the axis line segment OP rotates clockwise from O 2P2 and moves outwards to O 3P3; when the door 30 is opened from G 3 to G 4, the axis OP rotates clockwise from O 3P3 and moves outward to O ePe. Since the positioning groove 6 and the guiding groove 7 are arranged on the door body 30, the axis line segment OP represents the movement of the lux triangle block 5 arranged on the box body 10; the following is obtained: with the door body 30 as a reference, the lock body 30 keeps rotating clockwise and moving outwards relative to the door body 30 in the whole process from G 2 to G 4. According to the relativity of the movement, the door body 30 (i.e. the positioning groove 6 and the guiding groove 7) rotates anticlockwise and moves inwards relative to the box body 10 in the whole process of opening the door body 30 from G 2 to G 4 by taking the box body 10 as a reference object (i.e. taking the Lerlow triangle 5 as a reference object). That is, the door 30 is rotated counterclockwise and moved inward with respect to the cabinet 10 throughout the process of the door 30 being rotated to be opened from the closed state to G 2; i.e., the door body 30 is opened while being moved inward by a certain distance.
In connection with the process of opening the door body 30 from the closed state to G 2, it can be obtained that: in the process of opening the door body 30 from the closed state to G 4, the axis line segment OP keeps rotating clockwise and moves outwards, and the trend of the axis line segment OP moves from O 0P0 to O 1P1、O2P2、O3P3、OePe in sequence; namely, the door body 30 is taken as a reference, and the Lerlo triangle 5 always keeps clockwise rotation and outwards movement relative to the door body 30 in the whole process from the closed state to G 4. According to the relativity of the movement, the door body 30 rotates anticlockwise and moves inwards relative to the box body 10 in the whole process of opening the door body 30 from a closed state to G 4 about 90 degrees by taking the box body 10 as a reference object (namely taking the Lerlow triangle 5 as a reference object). Namely, in the whole process that the door body 30 is rotated and opened from the closed state to the position of G 4 about 90 DEG, the door body 30 is rotated anticlockwise and moved inwards relative to the box body 10; i.e., the door 30 is opened while being moved inward by a first distance. The first distance is a distance that the door body 30 moves when the door body 30 is opened from 0 ° to G 4.
In addition, in the present embodiment, when the door body 30 is rotated to be opened to 90 °, the door front wall 31 of the door body 30 is parallel to the first side wall of the case 10; wherein, the distance between the front wall 31 of the door body 30 and the first body side wall of the box body 10 is denoted as D, D E [0,3], unit: mm. Note that at this point the door front wall 31 is located either outboard or inboard of the first body side wall, or the door front wall 31 is coplanar with the first body side wall.
As shown in fig. 18, in the process of opening the door body 30 by G 4 to G max by rotation, the door body 30 is opened by G 4 to G max. During this process, the central axis of the hinge shaft 4 (positioning central axis P) is moved by the second positioning end point P e in a direction opposite to the withdrawal direction of the door sidewall 32 along the track S; specifically, the center axis of the hinge shaft 4 (positioning center axis P) is withdrawn from the second positioning end point P e along the trajectory S to the fourth displacement point P 4; in the process that the door body 30 is rotated and opened from G 2 to G 4 Excluding interval end point angle G 4, including interval end point G max), the first vertex a of the lux triangle 5 is always mated with the first guide bar 8, lux triangle 5/>Is always engaged with the second guide strip 9.
In the above opening process, the positioning groove 6 and the guiding groove 7 are used as reference objects, and when the door body 30 is opened from G 4 to G max, the axis line OP rotates clockwise from O ePe and moves inward to O 4P4. Since the positioning groove 6 and the guiding groove 7 are arranged on the door body 30, the axis line segment OP represents the movement of the lux triangle block 5 arranged on the box body 10; the following is obtained: with the door 30 as a reference, the lux triangle 5 (i.e., the case 10) rotates clockwise and moves inward with respect to the door 30. According to the relativity of the movement, the door body 30 (i.e. the positioning groove 6 and the guiding groove 7) rotates anticlockwise and moves outwards by a second distance relative to the box body 10 in the process that the door body 30 is opened from G 4 to G max by taking the box body 10 as a reference (i.e. the Lerlow triangle 5 as a reference).
To sum up, as shown in fig. 11-19, with the positioning slot 6 and the guide slot 7 as reference, the axis line OP (the connection line between the central axis of the hinge shaft 4 (the positioning central axis P) and the center O of the triangular block 5) is rotated G 4 clockwise and moved outwards by a first distance (from P0O0→P1O1→P2O2→P3O3→PeOe), to G 4 clockwise to G max > 90 ° and moved inwards by a second distance (from P eOe→P4O4)), wherein the first distance > the second distance is such that, when the door body 30 is opened to G max > 90 ° relative to the initial state (P 0O0), the axis line OP is rotated and moved outwards by a certain distance (the difference between the first distance and the second distance).
If the hinge shaft 4 and the triangular Lerlow block 5 are used as reference objects, the whole of the positioning slot 6 and the guide slot 7 rotates G 4 in the anticlockwise direction and moves inwards for a first distance, and then rotates G 4 in the anticlockwise direction to G max which is more than 90 degrees and moves outwards for a second distance; since the first distance > the second distance; when the door body 30 is opened to G max > 90 ° with respect to the initial state (the closed state of the door body 30), the positioning groove 6 and the guide groove 7 are finally moved inward by a certain distance. In this embodiment, the positioning groove 6 and the guiding groove 7 are disposed on the door 30, that is, the door 30 always keeps moving inward for a certain distance relative to the initial state (closed state) in the whole process of opening the door 30 to G max > 90 ° relative to the hinge fixed on the case 10, so as to effectively avoid touching the cabinet 100 in the opening process of the door 30.
In this embodiment, the second positioning end point P e is closer to the door sidewall 32 than the first positioning end point P 0, and the track line S extends along a straight line in a direction closer to the door sidewall 32; in this way, when the hinge shaft 4 moves in a direction approaching the door sidewall 32 (during the process of opening the door body 30 from the closed state to G 4), the door body 30 with the positioning slot 6 moves a certain distance away from the door sidewall 32 (inward), and the door body 30 moves inward, so that the side edge K is prevented from being too much beyond the side surface of the cabinet 10 to touch the cabinet 100.
As shown in fig. 20, with the case 10 (the hinge shaft 4 and the lux triangular block 5) as reference, the door 30 (the positioning slot 6 and the guide slot 7) is rotated and opened relative to the case 10, and the positions of the side edges K are sequentially positioned at K 0、K1、K2、K3、K4、K5 corresponding to the opening of the door 30 to 0 °, G 1、G2、G3、G4、Gmax; namely, in the process of opening the door body 30 to G max, the moving track of the side edge K is a curve where K 0、K1、K2、K3、K4、K5 is located at the same time. It can be derived that: in the whole process that the door body 30 rotates and moves inwards and then rotates and moves outwards, the side edges K move outwards for a certain distance and then keep moving inwards; and moves outwardly to a maximum position between the door body 30 being rotated to G 2 to G 3. In the embodiment, G 2∈[28°,30°],G3 is E [62 degrees, 65 degrees ] to obtain that when the door body 30 rotates to open at an angle of 28 degrees to 65 degrees, the side edge K moves outwards to the maximum point; compared with the opening mode of the door body 30 rotating around the fixed shaft, the side edges K always move outwards in the process of opening to 90 degrees. The arrangement in this embodiment effectively reduces the range of outward movement of the side edge K, and limits it to the range of the distance between the reference plane M (first body side wall) and the cabinet 100, thereby avoiding collision with the cabinet 100 during the opening of the door 30.
In the embodiment of the present application, when the door body 30 is rotated from the closed state (0 °) to G max > 90 °, the hinge shaft 4 moves along the track line S from the first positioning end point P 0 to the second positioning end point P e toward the door side wall 32, and then moves from the second positioning end point P e to the fourth displacement point P 4 toward the door side wall 32; simultaneously, the triangular Lerlow block 5 rotates clockwise and moves outwards for a first distance relative to the guide groove 7, and then rotates clockwise and moves inwards for a second distance; wherein the first distance > the second distance. Namely, in the whole process that the door body 30 is rotated and opened from a closed state (0 DEG) to G max & gt 90 DEG, the hinge shaft 4 firstly moves along the locating slot 6 from one end to the other end along a straight line, and then withdraws to move along the straight line; the triangular block 5 rotates clockwise and moves outwards with respect to the guide groove 7, and then rotates clockwise and moves inwards.
In the process of opening the door body 30 from the closed state to G 4, the hinge shaft 4 moves in a direction approaching the door sidewall 32 along a straight line, the lux triangle 5 rotates and moves in a direction approaching the door sidewall 32, and the door body 30 always moves inward (in a direction approaching the second body sidewall) by a first distance.
In the process that the door body 30 is opened from G 4 to the maximum angle G max, the hinge shaft 4 moves in a straight line in a direction away from the door sidewall 32, the lux triangle 5 rotates and moves in a direction away from the door sidewall 32, and the door body 30 moves outwardly a second distance.
That is, the door body 30 is opened to an opening angleWhen the door 30 is rotated, it is kept moving inward. Namely, the relative positions of the hinge shaft 4 and the positioning slot 6 are shown as/>, in the embodiment, by the triangular Lerlow block 5 and the guide slot 7The door body 30 is rotated and moved inward during the opening process in the initial state. Therefore, when the door 30 is closed, the first vertex a, the second vertex B, and the third vertex C of the triangular block 5 are not limited to the position a 0、B0、C0 in the present application, and may be disposed at the position a 1、B1、C1 in sequence, the position a 2、B2、C2 in sequence, and the position a 3、B3、C3 in sequence. Namely, in the present embodiment, the door body 30 is opened to/>The positions of the three vertices of the Shi Leluo with respect to the door body 30 may be set to the positions of the three vertices of the lux triangle 5 with respect to the door body 30 in the initial state when the door body 30 is closed.
In the first embodiment of the application, the position of the hinge shaft 4 in the positioning slot 6 and the position of the triangular block 5 in the guide slot 7 are always changed in the whole process of opening the door body 30 from the closed state to the maximum angle G max > 90 degrees, so that the situation of abrupt stress is avoided, and the movement is smoother.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
