[0031] The number of drawers 103 and slide rails 102 is multiple, which is evenly distributed in a straight line on the cabinet 101, the drawer 103 can slide along the slide rail 102 to realize opening and closing, which is prior art, and the present scheme will not be described in detail, and the skilled in the art can clearly know the working principle, which is not embodied in the present drawing.
[0032] The limiting assembly 200 has two groups, which are arranged on both sides of the drawer 103, including the limiting piece 201 on one side of the drawer 103, the limiting piece 201 is arranged to limit the opening state of the drawer 103, so as to prevent the drawer 103 from falling, one side of the limiting piece 201 is provided with adjusting piece 202, the adjusting piece 202 is arranged to adjust the position of the limiting piece 201, so as to adapt to the different opening state of the drawer 103.
[0033] The limiting piece 201 comprises a limiting plate 201a fixed in the cabinet body 101, the limiting plate 201a is L-shaped, and one end is fixed with the slide rail 102, the limiting plate 201a is used for limiting the opening position of the drawer 103, one side of the drawer 103 is provided with a sliding block 201b, one end of the sliding block 201b is fixed with a sliding plate 201c, the movement of the sliding block 201b can drive the sliding block 201b to move, the sliding plate 201c is fixed with a first fixed block 201d and a second fixed block 201e, the first fixed block 201d is rotatably connected with a moving plate 201f, the moving plate 201f can rotate around the first fixed block 201d, the other end of the moving plate 201f is fixed with a fixed plate 201g, and the fixed plate 201g is provided with a sliding groove 201g-1, and the second fixed block 201e can slide in the sliding groove 201g-1.
[0034] The first fixed block 201d is close to one end of the moving plate 201f and is not in the middle position, so that the moving plate 201f will rotate around the first fixed block 201d under the action of gravity when not being limited, and since the positions of the first fixed block 201d and the second fixed block 201e are unchanged, when the moving plate 201f rotates around the first fixed block 201d, the fixed plate 201g rotates, at this time, the second fixed block 201e will slide in the sliding groove 201g-1 and will not hinder the rotation of the moving plate 201f.
[0035] One end of the moving plate 201f can cooperate with the limiting plate 201a, when the two are in contact, the opening position of the drawer 103 will be limited, so that the opening position of the drawer 103 can be prevented from falling.
[0036] Embodiment 2
[0037] Reference Figures 1-8 As a second embodiment of the utility model, the embodiment is based on the previous embodiment.
[0038] Specifically, one end of the moving plate 201f has a protrusion 201f-1, and the protrusion 201f-1 is similar to the shape of a hook.
[0039] In the initial position, the moving plate 201f is located away from the limiting plate 201a, and the protrusion 201f-1 will be in contact with the bottom of the slide rail 102, at this time, the rotation of the moving plate 201f around the first fixed block 201d will be limited, with the opening of the drawer 103, when the protrusion 201f-1 moves to the vicinity of the limiting plate 201a, since the horizontal height of the limiting plate 201a is higher than the bottom of the slide rail 102, the protrusion 201f-1 will be in contact with the limiting plate 201a, under the action of gravity, the moving plate 201f rotates around the first fixed block 201d, and then the second fixed block 201e is in contact with the upper end surface of the sliding groove 201g-1, and the protrusion 201f-1 will limit the drawer 103 from being further opened, thereby preventing the drawer 103 from falling.
[0040] Specifically, the adjusting member 202 includes an upper slide 202a and a lower slide 202b fixed to the drawer 103, and the upper slide 202a and the lower slide 202b are matched with the sliding block 201b, the sliding block 201b can slide along the two slides, the sliding block 201b is T-shaped, and the T-shaped structure enables the sliding block 201b to slide along the two slides without being separated from them. When the sliding block 201b slides along the upper slide 202a and the lower slide 202b, the position of the sliding block 201b relative to the entire drawer 103 will also change, while the position of the limiting plate 201a will not change because it is fixed to the cabinet 101, so that when the sliding block 201b is moved, the moving plate 201f can be driven to move synchronously, thereby adjusting the opening size of the drawer 103.
[0041] Specifically, the lower slide 202b is provided with a first moving slot 202b-1, and the first moving slot 202b-1 is provided with a locking block 202c, one end of the locking block 202c is fixed with a first spring 202d, and the other end of the first spring 202d is fixed with the inner wall of the first moving slot 202b-1. The first spring 202d is arranged to apply a continuous pushing force to the locking block 202c, so that one end face of the locking block 202c can protrude from the end face of the lower slide 202b under the condition of no other external force.
[0042] The sliding block 201b is provided with a locking slot 201b-1, and the locking block 202c can be clamped with the locking slot 201b-1. When the two are clamped, the position of the sliding block 201b in the lower slide 202b will be locked, so that the sliding block 201b cannot slide randomly in the upper slide 202a and the lower slide 202b, thereby limiting the position of the limiting member 201. At this time, when the protrusion 201f-1 contacts the limiting plate 201a, the position of the moving plate 201f and the protrusion 201f-1 cannot be changed due to the locked position of the sliding block 201b, and the limiting plate 201a itself cannot be moved, thereby limiting the drawer 103 from being further opened.
[0043] When the locking block 202c is no longer clamped with the locking slot 201b-1, the sliding block 201b can slide in the upper slide 202a and the lower slide 202b, thereby changing the position of the limiting member 201. At this time, the drawer 103 is opened, and when the protrusion 201f-1 contacts the limiting plate 201a, the position of the sliding block 201b can be changed, and the limiting plate 201a will apply a reverse pushing force to the protrusion 201f-1. The sliding block 201b will slide in the upper slide 202a and the lower slide 201b, while the protrusion 201f-1 is always in contact with the limiting plate 201a, thereby further pulling open the drawer 103.
[0044] When the drawer 103 is opened to the maximum limit, the locking block 202c and the locking slot 201b-1 will be coaxial, and under the action of the first spring 202d, they are mutually clamped, so that the sliding block 201b is position-locked, the further opening of the drawer 103 is limited, and the drawer 103 is prevented from falling.
[0045] Specifically, one end of the locking block 202c is inclined, the shape of the locking slot 201b-1 corresponds to the shape of the locking block 202c, and the number of the locking slot 201b-1 is multiple. In the initial state, the locking block 202c is clamped with the locking slot 201b-1. When the drawer 103 is opened, and the drawer 103 does not need to be completely opened, the sliding block 201b will not slide away from the direction of the flat plate 104, so that the protrusion 201f-1 cooperates with the limiting plate 201a, and the further opening of the drawer 103 is limited, and the falling is prevented. At this time, since the drawer 103 is not completely opened, a small amount of gravity of the drawer 103 will act on the protrusion 201f-1 of the moving plate 201f, thereby prolonging the service life of the moving plate 201f.
[0046] Through the inclined setting, when the sliding block 201b moves from the position away from the flat plate 104 to the flat plate 104, the inclined surface of the locking slot 201b-1 will extrude the inclined surface of the locking block 202c, so that the first spring 202d is compressed, and the locking block 202c moves into the first moving slot 202b-1, and the sliding of the sliding block 201b is not affected.
[0047] Specifically, one end of the locking block 202c is fixed with an extension plate 202e, the second moving slot 202b-2 is arranged on the lower sliding channel 202b, the extension plate 202e slides in the second moving slot 202b-2, the first moving slot 202b-1 is communicated with the second moving slot 202b-2, and the flat plate 104 is provided with a slot corresponding to the extension plate 202e. One end of the extension plate 202e penetrates through the flat plate 104 and protrudes from the surface of the flat plate 104, and is used for unlocking the clamping of the locking block 202c and the locking slot 201b-1.
[0048] When it is needed to unlock the locking of the sliding block 201b, the extension plate 202e is pushed, so that the first spring 202d is compressed, the locking block 202c moves into the first moving slot 202b-1, and the sliding of the sliding block 201b is not affected.
[0049] Embodiment 3
[0050] Reference Figures 1-8 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.
[0051] Specifically, the extension plate 202e is provided with a guide groove 202e-1, the number of the guide grooves 202e-1 is multiple, a guide column 202f is inserted into the guide groove 202e-1, both ends of the guide column 202f are fixed to the inner wall of the second moving groove 202b-2, the number of the guide column 202f is consistent with and corresponds to the guide groove 202e-1, because the extension plate 202e is long, the extension plate 202e is moved at one end by the cooperation of the guide column 202f and the guide groove 202e-1, so that the extension plate 202e can be stably moved in the second moving groove 202b-2, and then the locking block 202c can be moved.
[0052] The locking block 202c is provided with a limiting groove 202c-1, and the first moving groove 202b-1 is fixed with a limiting column 202h, so that the stability of the locking block 202c is ensured by the cooperation of the two.
[0053] Specifically, the guide column 202f is fixed with a second spring 202g, both ends of the second spring 202g are fixed to the extension plate 202e and the inner wall of the second moving groove 202b-2 respectively, the second spring 202g applies a continuous pushing force to the extension plate 202e, so that the extension plate 202e cannot be moved downward due to its own gravity under the condition that there is no other external force, and then the locking block 202c is separated from the locking groove 201b-1, and the locking of the sliding block 201b is affected.
[0054] Specifically, one end of the sliding block 201b is fixed with a third spring 201h, the other end of the third spring 201h is fixed to the flat plate 104, the third spring 201h applies a pulling force to the sliding block 201b, and the elastic force of the third spring 201h is greater than that of the first spring 202d.
[0055] In the initial state, the third spring 201h will be in a relaxed state, at this time, the locking block 202c is engaged with one of the locking grooves 201b-1, when the sliding block 201b slides in the upper slide 202a and the lower slide 202b, the third spring 201h will be stretched, because the protrusion 201f-1 of the moving plate 201f is always in contact with the limiting plate 201a, as the drawer 103 is further opened, the third spring 201h will be further stretched, because of the gravity of the drawer 103, the hand of the person releases the drawer 103, and no longer applies pressure to the drawer 103, the third spring 201h will not recover, and then the position of the drawer 103 is in the moving position.
[0056] When the drawer 103 is pushed to reset, the third spring 201h will recover, the inclined surface of the locking groove 201b-1 will press the inclined surface of the locking block 202c, so that the first spring 202d is compressed, the locking block 202c moves into the first moving groove 202b-1, and does not affect the sliding of the sliding block 201b.
[0057] Specifically, the handle 105 is fixed on the plate 104, the number of the handle 105 is two, pulling or dragging the handle 105 can drive the drawer 103 to move synchronously.
[0058] In use, when the drawer 103 is not required to open to a large extent, the handle 105 is pulled to open the drawer 103, the protrusion 201f-1 on the moving plate 201f is in contact with the bottom of the slide rail 102, when the protrusion 201f-1 moves to the vicinity of the limiting plate 201a, the moving plate 201f is rotated around the first fixed block 201d under the action of gravity, and then the second fixed block 201e is in contact with the upper end surface of the sliding groove 201g-1, the protrusion 201f-1 will limit the drawer 103 from being further opened, thereby preventing the drawer 103 from falling.
[0059] When the drawer 103 is required to be opened to a large extent, the extension plate 202e is pushed, the first spring 202d is compressed, and the locking block 202c moves into the first moving groove 202b-1, at this time, the drawer 103 is opened again, and the extension plate 202e is released, when the protrusion 201f-1 is in contact with the limiting plate 201a, the position of the sliding block 201b can be changed, the limiting plate 201a will apply a reverse thrust to the protrusion 201f-1, the sliding block 201b will slide in the upper slide 202a and the lower sliding block 201b, and the protrusion 201f-1 is always in contact with the limiting plate 201a, thereby the drawer 103 can be further pulled open, when the drawer 103 is opened to the maximum extent, the locking block 202c and the locking groove 201b-1 are engaged again, thereby the position of the sliding block 201b is locked, the drawer 103 is limited from being further opened, and the drawer 103 is prevented from falling.
[0060] When the drawer 103 is pushed to reset, the third spring 201h is restored, the inclined surface of the locking groove 201b-1 presses the inclined surface of the locking block 202c, thereby the first spring 202d is compressed, the locking block 202c moves into the first moving groove 202b-1, and the sliding of the sliding block 201b is not affected, under the action of the third spring 201h, the sliding block 201b is reset, and the next use is facilitated.
[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
