[0005] 2. Specific technical solutions

[0006] A sliding limit device comprises a guide rail structure and a sliding device, wherein the sliding device is installed on the guide rail structure, a rotation limit clamping plate is arranged above the guide rail structure, a rotating shaft structure is connected to the upper part of the rotation limit clamping plate, a bayonet structure is arranged at the end of the sliding device, the top of the bayonet structure is flat, and a limiting clamping head is arranged on the side of the rotation limit clamping plate close to the bayonet structure. In a natural state, the top of the limiting clamping head is horizontal, and its height is lower than the flat top of the bayonet structure. In the limited state, the limiting clamping head cooperates and clamps into the bayonet structure to limit the rotation of the rotation limit clamping plate around the rotating shaft structure.

[0007] Preferably, the sliding device is composed of a pulley block structure and a pulley block mounting seat, and the top of the pulley block mounting seat is a square tubular structure.

[0008] Preferably, the guide rail structure has a triangular cross-section, the pulley block structure includes at least two pulleys, and a triangular groove is provided in the middle of the pulley, and the triangular groove cooperates with the guide rail structure.

[0009] Preferably, a vertical support frame is also included, and the guide rail structure and the rotating shaft structure are arranged at different heights of two groups of vertical support frames.

[0010] As a preferred embodiment, the rotation limit clamping plate is in an isosceles trapezoidal shape on the upper side of the limit clamping head, and the rotation limit clamping plate is in a balancing triangle plate structure on the lower side of the limit clamping head.

[0011] Preferably, the rotating shaft structure is arranged on the top of the rotation limiting clamping plate.

[0012] The beneficial effects of the utility model are as follows: a rotation limit card plate is provided to be rotatably connected to the rotating shaft structure, and when the sliding device and its components are installed from the side of the rotation limit card plate without the limit card head, the rotation limit card plate is pushed by the end face of the sliding device to rotate around the rotating shaft structure to make way, and can be installed relatively easily without being restricted; when the sliding device is installed, it will be limited to move in a certain position range by the rotation limit card plate, and when it slides along the guide rail structure to the position of the rotation limit card plate, the limit card head cooperates and snaps into the bayonet structure in the sliding device, and the top of the limit card head fits the flat top of the bayonet structure, so that the end face of the sliding device cannot push the rotation limit card plate to The structure rotates around the rotating shaft to make way, thereby completing the automatic limiting work; if it is necessary to remove the sliding device and other components, the rotating limiting clamping plate is controlled or manually pulled so that when the end face of the sliding device slides out of the corresponding position of the rotating limiting clamping plate, the limiting clamping head cannot cooperate to be inserted into the clamping structure in the sliding device. The entire sliding limiting device is easy to use and has extremely low cost. The isosceles trapezoidal shape on the upper side of the rotating limiting clamping plate and the balancing triangle plate structure on the lower side of the rotating limiting clamping plate are conducive to the rotating limiting clamping plate maintaining a vertical and vertical balanced state. At the same time, the inclined surfaces on both sides facilitate smoother passage when it is not limited and in the unlimited direction of the sliding device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example:

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown: a sliding limit device, including a guide rail structure 1 and a sliding device, the sliding device is installed on the guide rail structure 1, the number of the guide rail structures 1 is three groups, at least one group of guide rail structures 1 is also acceptable, because it is stored in layers, generally multiple layers, but too many layers are not conducive to operation, each group of guide rail structures 1 is composed of two parallel guide rail structures 1, two shelf board structures 2 are movably arranged between the two parallel guide rail structures 1, at least one shelf board structure 2 is sufficient, the guide rail structure 1 is long enough and stable to set more shelf board structures 2, pulley group structures 3 are provided at the bottom of both sides of the shelf board structure 2, the pulley group structures 3 are respectively matched with the two parallel guide rail structures 1, and spacer containers 4 are evenly arranged on the shelf board structure 2, there are card slots for storing workpieces between the spacer containers 4, and the shape of the card slots is consistent with the shape of the workpiece, and the surface of the spacer container 4 in contact with the workpiece is provided with a cushion layer, so as to further avoid deformation of the workpiece or scratching of the workpiece during storage.

[0024] The sliding device is composed of a pulley block structure 3 and a shelf plate structure 2. The shelf plate structure 2 is composed of a middle shelf layer 21 and pulley block mounting seats 22 on both sides. The pulley block mounting seats 22 are connected to the shelf layer 21. The pulley block structure 3 is installed on the pulley block mounting seats 22. Positioning seats 23 are evenly arranged on the upper surface of the shelf layer 21. The bottom of the spacing container 4 has a positioning slot, and the positioning seat 23 cooperates with the positioning slot, wherein the shelf layer 21 is a solid layer plate or a hollow frame structure; and the sliding device is at least composed of the pulley block structure 3 and the pulley block mounting seat 22. It is not limited to what the pulley block mounting seat 22 is connected to to form what device.

[0025] It also includes two groups of vertical support frames 5, which are arranged in parallel with each other. Three groups of guide rail structures 1 are arranged in parallel at different heights of the two groups of vertical support frames 5 in the vertical direction. The guide rail structure 1 can also be directly installed on a relative support such as a wall, and each group of vertical support frames 5 can be composed of multiple independent support columns, or connected as a whole. A number of sliding limit devices 6 are also installed on the vertical support frame 5, each of which is respectively arranged at the end position of the guide rail structure 1, and other middle positions are also acceptable, but generally there is no such requirement, which is used to limit the shelf board structure 2 from accidentally sliding out and falling off to avoid safety accidents.

[0026] in:

[0027] The sliding limit device 6 includes a rotation limit card plate 61 and a shaft structure 62. The rotation limit card plate 61 is arranged above the guide rail structure 1. The shaft structure 62 is connected to the upper part of the rotation limit card plate 61. The shaft structure 62 is best arranged at the top of the rotation limit card plate 61.

[0028] A bayonet structure 63 is provided at the end of the sliding device, and the top of the bayonet structure 63 is flat. A limiting clamp head 64 is provided on the side of the rotation limit clamp plate 61 close to the bayonet structure 63, or limiting clamp heads 64 can be provided on both sides, that is, both sides are limited. In the natural state, the top of the limiting clamp head 64 is horizontal, and its height is lower than the flat top of the bayonet structure 63. In the limited state, the limiting clamp head 64 cooperates to fit into the bayonet structure 63 to limit the rotation of the rotation limit clamp plate 61 around the shaft structure 62.

[0029] Therefore, there is a gap between the top of the limiting clamp 64 and the flat top of the bayonet structure 63. When the diameter of the limiting clamp 64 is small or the limiting clamp 64 is short, the gap should be designed to be small, otherwise it can be designed to be larger to facilitate the top of the limiting clamp 64 to fit the bayonet structure 63.

[0030] The top of the pulley assembly mounting seat 22 is a square tubular structure, and the square inner hole of the square tubular structure is the bayonet structure 63, which achieves lightweight processing; the rotating shaft structure 62 and the corresponding guide rail structure 1 are arranged at different heights of the two sets of vertical support frames 5, and can also be installed at different heights on relative supports such as walls.

[0031] The rotation limit clamp plate 61 is in the shape of an isosceles trapezoid on the upper side of the limit clamp head 64, which is beneficial for the limit clamp head 64 of the rotation limit clamp plate 61 to be balanced and hammered downward on one side, and is beneficial for the top height of the limit clamp head 64 to be designed to be lower than the flat top of the bayonet structure 63, that is, the limit clamp head 64 is easier to be inserted into the bayonet structure 63, and the rotation limit clamp plate 61 is a balancing triangle plate structure on the lower side of the limit clamp head 64, which is designed to ensure that the top of the limit clamp head 64 is in a horizontal state, that is, a balanced state, and the oblique lines on both sides facilitate smoother passage when it is not limited and in the non-limiting direction of the sliding device.

[0032] The cross-section of the guide rail structure 1 is triangular, and the pulley group structure 3 includes three pulleys, at least two pulleys are sufficient. The three pulleys are because the shelf plate structure 2 will be widened along with the long strip workpiece, and the middle pulley plays a supporting role. A triangular groove is provided in the middle of the pulley, and the triangular groove cooperates with the guide rail structure 1 to avoid derailment. Other methods can also be used to avoid derailment, such as T-shaped rails.

[0033] The implementation principle of its application scenario is as follows: by arranging pulley group structures at the bottom of both sides of the shelf board structure, the shelf board structure can be moved and dislocated along the horizontal direction of the guide rail structure, so as to facilitate storage and retrieval operations, and facilitate adjustment so that the storage state is sufficiently regular. At the same time, a spacing container 4 is designed, and there are card slots between the spacing containers 4 that are consistent with the shape of the workpiece, further ensuring that the storage state is sufficiently regular and the operation is convenient, avoiding affecting the subsequent use quality of volatile products such as injection molded parts; and the shelf board structure can be pulled out from between the guide rail structures, the guide rail structure does not occupy the passage space, and the shelf board structure can be stacked separately, reducing the space occupied by the shelf when not in use.

[0034] The implementation principle of the sliding limit device 6 is as follows: a rotation limit card plate 61 is provided to be rotatably connected to the rotating shaft structure 62. When the sliding device is installed from the side of the rotation limit card plate 61 without the limit card head 64, the rotation limit card plate 61 is pushed by the end face of the sliding device to rotate around the rotating shaft structure 62 to make way, and can be installed relatively easily without being restricted; when the sliding device is installed, it will be limited to move in a certain position range by the rotation limit card plate 61. When it slides along the guide rail structure 1 to the position of the rotation limit card plate 61, the limit card head 64 cooperates and snaps into the bayonet structure 63 in the sliding device, and the top of the limit card head 64 fits the flat top of the bayonet structure 63, so that the end face of the sliding device cannot push the rotation limit card plate 61 to rotate around the rotating shaft structure 62 to make way, because the rotation limit card plate 61 cannot have a large vertical displacement, and its vertical displacement is limited. The top of the positioning clamp head 64 fits into the gap between the top of the flat mouth of the bayonet structure 63, and the rotation limit clamp plate 61 is a rigid component, and its circular motion is a combination of horizontal displacement and vertical displacement, so it cannot rotate, thereby completing the automatic limiting work; if it is necessary to remove the sliding device and other components, the rotation limit clamp plate 61 is controlled or manually pulled so that when the end face of the sliding device slides out of the corresponding position of the rotation limit clamp plate 61, the limiting clamp head 64 cannot be matched to be inserted into the bayonet structure 63 in the sliding device. The entire sliding limit device 6 is easy to use and has extremely low cost of use. The isosceles trapezoidal shape on the upper side of the rotation limit clamp plate 61 and the balancing triangle plate structure on the lower side of the rotation limit clamp plate 61 are conducive to the rotation limit clamp plate 61 maintaining a vertical and vertical balanced state. At the same time, the inclined surfaces on both sides facilitate smoother passage when it is not limited and in the unlimited direction of the sliding device.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
