Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to an anti-falling shelf. Background Art

[0002] A shelf is a storage device widely used in industries such as retail, warehousing, and logistics for displaying or storing goods.

[0003] In the existing patent literature, a patent with a publication number of CN 219895031 U and a name of "Shelf" is for a warehousing shelf or a logistics shelf. The goods placed on the shelf are heavy and large in volume. When such goods are placed on the placement area of this patent, since there is no facility to block or intercept the goods on the front side of the placement area, after the shelf is impacted by an external force, the goods are very likely to fall from a high place, and at that time, it is very easy to injure the passing staff and also cause losses to the goods. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an anti-falling shelf. The anti-falling shelf can launch a steel wire rope through an anti-falling steel wire launching mechanism, and intercept the steel wire rope on the front side of the placement area through the cooperation of a hook and a hanging ring, which can effectively prevent the goods on the placing board from falling, and can not only ensure the personal safety of the passing staff, but also ensure the property safety of the goods.

[0005] To solve the above technical problems, the technical solution of the utility model is realized as follows:

[0006] An anti-falling shelf includes vertically arranged columns, and multiple layers of placing boards are installed on the column bodies of the columns and are distributed in an upper and lower array.

[0007] An anti-falling steel wire launching mechanism and an anti-falling steel wire receiving mechanism concentrically fixed on the column are installed in the placement area of each layer of placing board. The anti-falling steel wire launching mechanism and the anti-falling steel wire receiving mechanism are located on the same horizontal plane and are alternately distributed in sequence along this horizontal plane;

[0008] The anti-falling steel wire launching mechanism includes a launching outer shell. A reel is rotatably connected in the middle of the interior of the launching outer shell. A steel wire rope is stored in the reel, and a hook located outside the launching outer shell is fixed at the end of the steel wire rope.

[0009] The anti-falling steel wire receiving mechanism includes a receiving outer shell. A positioning frame is fixedly connected in the middle of the exterior of the receiving outer shell, and a hanging ring is fixed on the positioning frame.

[0010] The hook can pull the steel wire rope to hang on the hanging ring. At this time, the steel wire rope completely intercepts the front side of the placement area.

[0011] By adopting the above scheme, the anti-falling shelf can launch the steel wire rope through the anti-falling steel wire launching mechanism, and intercept the steel wire rope at the front side of the placement area through the cooperation of the hook and the hanging ring, which can effectively prevent the goods on the storage board from falling, thereby ensuring the personal safety of the staff passing by and the property safety of the goods.

[0012] As a preferred embodiment of an anti-falling shelf, the anti-falling wire receiving mechanism also includes two groups of one-way self-locking ratchets, which are respectively located above and below the reel and are coaxially connected to the reel, and two groups of elastic self-locking components are installed on the outside of the launching outer shell, and each group of elastic self-locking components controls the unidirectional rotation of a group of one-way self-locking ratchets; wherein the rotation directions of the two groups of one-way self-locking ratchets are completely opposite.

[0013] By adopting the above scheme, in order to achieve the self-locking of the reel, when the wire rope intercepts the placement area, the two sets of one-way self-locking ratchet wheels can be self-locked through the elastic self-locking component. At this time, the two sets of one-way self-locking ratchet wheels cannot rotate. Then the reel is self-locked, and the wire rope will be locked, thereby improving the interception strength of the wire rope.

[0014] As a preferred embodiment of the anti-falling shelf, the elastic self-locking component includes a self-locking plug core, the plug of the self-locking plug core is a round head, a guide seat is fixed on the self-locking plug core, the guide seat is slidably connected to a guide shaft fixed on the outside of the launch shell, and a spring is mounted on the guide shaft to push the guide seat to move toward the location of the one-way self-locking ratchet;

[0015] Among them, the self-locking plug is rotatably connected to a rotating sleeve located outside the launch shell, two symmetrical side ears are fixed on the outer wall of the rotating sleeve, and blocking protrusions located above and below the self-locking plug are fixed outside the launch shell; damping is arranged on the contact surface between the rotating sleeve and the self-locking plug.

[0016] By adopting the above scheme, in order to control the locking of the one-way self-locking ratchet, the self-locking plug can pass through the launching outer shell and extend into the interior of the launching outer shell; when the side ear is in a horizontal state, the self-locking plug is under the elastic action of the spring, and the plug of the self-locking plug can abut between two adjacent ratchet teeth of the one-way self-locking ratchet, so that the one-way self-locking ratchet is self-locked; when the side ear is in a vertical state, the side ear will abut against the blocking protrusion, and the plug of the self-locking plug will be disengaged from between two adjacent ratchet teeth of the one-way self-locking ratchet, and the one-way self-locking ratchet will be unlocked.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The anti-falling shelf can launch a steel wire rope through an anti-falling steel wire launching mechanism. By the cooperation of a hook and a hanging ring, the steel wire rope is intercepted on the front side of the placement area, which can effectively prevent the goods on the placement board from falling, ensuring both the personal safety of the passing staff and the property safety of the goods.

[0019] 2. To achieve the self-locking of the reel, when the steel wire rope intercepts the placement area, the two-way self-locking ratchets can be self-locked through an elastic self-locking component. At this time, neither of the two-way self-locking ratchets can rotate, and then the reel is self-locked, so that the steel wire rope will be locked, thereby enhancing the interception strength of the steel wire rope.

[0020] 3. To control the locking of the two-way self-locking ratchet, the self-locking core can penetrate through the launching housing and extend into the interior of the launching housing. When the side ear is in a horizontal state, under the elastic action of the spring, the plug of the self-locking core can abut between two adjacent ratchet teeth of the two-way self-locking ratchet, so that the two-way self-locking ratchet is self-locked. When the side ear is in a vertical state, the side ear will abut against the blocking protrusion, and at this time, the plug of the self-locking core will disengage from between two adjacent ratchet teeth of the two-way self-locking ratchet, so that the two-way self-locking ratchet is unlocked.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0032] As Figures 1 to 8 shown, an anti-falling shelf includes a vertically arranged vertical column 1, and a plurality of layers of storage boards 2 are installed on the column body of the vertical column 1 in an upper and lower array; an anti-falling wire launching mechanism 3 and an anti-falling wire receiving mechanism 4 concentrically fixed on the vertical column 1 are installed in the placement area of each layer of storage board 2. The anti-falling wire launching mechanism 3 and the anti-falling wire receiving mechanism 4 are located on the same horizontal plane and are alternately distributed in sequence along this horizontal plane; the anti-falling wire launching mechanism 3 includes a launching outer shell 301, a reel 302 is rotatably connected in the middle of the interior of the launching outer shell 301, a steel wire rope 303 is stored in the reel 302, and a hook 304 located outside the launching outer shell 301 is fixed at the end of the steel wire rope 303; the anti-falling wire receiving mechanism 4 includes a receiving outer shell 401, a positioning frame 402 is fixedly connected in the middle of the exterior of the receiving outer shell 401, and a hanging ring 403 is fixed on the positioning frame 402; the hook 304 can pull the steel wire rope 303 to be suspended on the hanging ring 403, and at this time, the steel wire rope 303 completely intercepts the front side of the placement area.

[0033] The anti-falling shelf can launch a steel wire rope 303 through the anti-falling steel wire launching mechanism 3. By the cooperation of the hook 304 and the hanging ring 403, the steel wire rope 303 is intercepted at the front side of the placement area, which can effectively prevent the goods on the placement board 2 from falling, ensuring both the personal safety of the passing staff and the property safety of the goods.

[0034] As Figures 5 to 7 shown, the anti-falling steel wire receiving mechanism 4 further includes two groups of one-way self-locking ratchets 305. The two groups of one-way self-locking ratchets 305 are respectively located above and below the reel 302 and are concentrically rotatably connected to the reel 302. Two groups of elastic self-locking components 5 are installed outside the launching housing 301, and each group of elastic self-locking components 5 correspondingly controls the one-way rotation of one group of one-way self-locking ratchets 305; wherein, the rotation directions of the two groups of one-way self-locking ratchets 305 are completely opposite. In order to realize the self-locking of the reel 302, when the steel wire rope 303 intercepts the placement area, the two groups of one-way self-locking ratchets 305 can be self-locked through the elastic self-locking components 5. At this time, neither of the two groups of one-way self-locking ratchets 305 can rotate, and then the reel 302 is self-locked, so that the steel wire rope 303 will be locked, thereby enhancing the interception strength of the steel wire rope 303.

[0035] As Figures 6 to 7 shown, the elastic self-locking component 5 includes a self-locking core 501. The plug of the self-locking core 501 is a round head. A guiding seat 502 is fixed on the self-locking core 501. The guiding seat 502 is slidably connected to a guiding shaft 503 fixed outside the launching housing 301. A spring 504 that pushes the guiding seat 502 to move towards the one-way self-locking ratchet 305 is sleeved on the guiding shaft 503;

[0036] wherein, a rotating sleeve 505 located outside the launching housing 301 is rotatably connected to the self-locking core 501. Two symmetrically arranged side ears 506 are fixed on the outer side wall of the rotating sleeve 505. Blocking protrusions 507 located above and below the self-locking core 501 are fixed outside the launching housing 301; a damping is provided on the contact surface between the rotating sleeve 505 and the self-locking core 501.

[0037] In order to control the locking of the one-way self-locking ratchet 305, the self-locking core 501 can penetrate through the launching housing 301 and extend into the interior of the launching housing 301; when the side ears 506 are in a horizontal state, under the elastic action of the spring 504, the plug of the self-locking core 501 can abut between two adjacent ratchet teeth of the one-way self-locking ratchet 305 at this time, so that the one-way self-locking ratchet 305 is self-locked; when the side ears 506 are in a vertical state, the side ears 506 will abut against the blocking protrusions 507, and at this time the plug of the self-locking core 501 will disengage from between two adjacent ratchet teeth of the one-way self-locking ratchet 305, so that the one-way self-locking ratchet 305 is unlocked.

[0038] The working principle of this utility model:

[0039] When in use, after placing the goods in the placement area, in order to prevent the goods from falling, the anti-falling wire launching mechanism 3 launches the wire rope 303, and the hook 304 cooperates with the hanging ring 403 to intercept the wire rope 303 at the front side of the placement area, which can effectively prevent the goods on the storage plate 2 from falling, thereby ensuring the personal safety of the staff passing by and the property safety of the goods.

[0040] Before launching the wire rope 303, the two sets of one-way self-locking ratchets 305 are self-locked in the unlocked state by operating the elastic self-locking component 5, that is: the self-locking plug 501 is pulled outward, and then the rotating sleeve 505 is rotated to make the side ear 506 in a vertical state, and then the side ear 506 will abut against the blocking protrusion 507. At this time, the plug of the self-locking plug 501 will be disengaged from between the two adjacent ratchet teeth of the one-way self-locking ratchet 305, then the two sets of one-way self-locking ratchet 305 are unlocked, and then the wire rope 303 can be launched.

[0041] After launching the wire rope 303, the rotating sleeve 505 is rotated again to make the side ear 506 in a horizontal state, and then the self-locking plug 501 is elastically acted upon by the spring 504. At this time, the plug of the self-locking plug 501 can abut between two adjacent ratchet teeth of the one-way self-locking ratchet 305, and then the two sets of one-way self-locking ratchet wheels 305 are self-locked, and the fixation of the wire rope 303 can be completed.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
