Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and more specifically, it relates to a stackable self-locking material frame. Background Technology

[0002] Turnover bins are commonly used for transporting products or materials and are widely used in industries such as machinery, automotive, home appliances, light industry, and electronics. Taking the machining field as an example, turnover bins are typically used to transfer or store materials between different production lines, which to some extent helps improve processing efficiency and workstation utilization. Therefore, improving the structure of turnover bins is particularly necessary.

[0003] Depending on the type of material they contain, turnover bins typically include bins for shaft parts, bins for disc-shaped parts, and bins for sheet metal parts. However, existing turnover bins for storing shaft parts have several shortcomings. For example, since shaft parts of different specifications usually have different outer diameters and lengths, existing turnover bins are not suitable for transporting shaft parts with varying dimensions within a certain range. The specifications and types of shaft parts that can be transported are very limited, resulting in poor versatility. Furthermore, some turnover bins for shaft parts cannot be stacked vertically, thus requiring a large floor space.

[0004] Therefore, various stackable material boxes have appeared on the market. For example, a turnover material box for shaft parts with patent publication number CN208963581U. This utility model adjusts the position of the limiting baffle relative to the main frame by adjusting the locking part, thereby adjusting the insertion depth of the shaft parts that abut against the limiting baffle. With the help of the auxiliary frame, it is suitable for holding shaft parts of different specifications. Moreover, the layer-by-layer stacking auxiliary frame is conducive to stacking multiple layers of shaft parts, thus improving its versatility and reducing the floor space.

[0005] However, the device has some problems during use, resulting in defects. First, the stacking method requires manual aiming to ensure that the frames can be stacked. If the frame is light, the operation is not difficult. However, when the frame is made of metal or there are workpieces inside the frame, the stacking operation becomes more difficult and inconvenient. Second, the locking and fixing operation is relatively complicated and cannot achieve self-locking, requiring manual operation.

[0006] Therefore, in order to solve the above-mentioned technical problems, this application proposes a stackable self-locking material frame. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stackable self-locking material frame.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stackable self-locking material frame, comprising two material rack units, which are stacked together;

[0009] The two stacked rack units are locked together by several connecting and locking components;

[0010] The connecting locking assembly includes a pin and a limiting seat coaxially connected to one end of the pin. The other end of the pin has a switching groove, and a locking mechanism is rotatably connected inside the switching groove.

[0011] The locking mechanism includes a connecting piece, a boss, and a through post. The connecting piece is inserted into the switching groove. A through hole is formed through the connecting piece and the switching groove. The through post is installed in the through hole inside the switching groove. The connecting piece is rotatably connected to the outside of the through post through the through hole. The end of the connecting piece away from the switching groove is also connected to the boss.

[0012] By incorporating a connecting locking assembly and a rack unit, two rack units can be stacked on top of each other and secured by a locking mechanism. The locking mechanism automatically locks the racks without requiring additional operation, significantly improving practicality. Additionally, each rack unit has an outwardly tilting locking element at its top. This locking element serves two purposes: firstly, it cooperates with the locking mechanism for securing the racks, and secondly, it assists in positioning the racks during stacking, greatly improving operational efficiency.

[0013] Preferably, the material rack unit includes a central frame, a bottom frame, and a top frame. The bottom frame is formed by splicing two first bottom rods and two second bottom rods. The two first bottom rods and two second bottom rods are arranged in a mirror-symmetrical manner. The bottom frame, the central frame, and the top frame are stacked sequentially from low to high. The upper and lower end faces of the central frame are provided with several support columns, which are connected to the bottom frame and the top frame respectively through the several support columns on the upper and lower end faces.

[0014] The second bottom rod has a sealing plate installed inside. The sealing plate has fixing holes symmetrically arranged at both ends. Locking holes are also symmetrically arranged at both ends of the first bottom rod. Locking parts are arranged around the top frame. Bottom supports are also evenly and crosswise arranged between the inner sides of the bottom frame.

[0015] When the rack units are stacked, the bottom frame and top frame of one rack unit are stacked and connected, and the locking component corresponds to the locking hole and the fixing hole. The locking mechanism passes through the locking component, the locking hole and the fixing hole to lock.

[0016] By setting a bottom frame, a middle frame, and a top frame in the material rack unit, and connecting the bottom frame and the top frame to both sides of the middle frame through support columns, the stability of the material rack is achieved.

[0017] Preferably, the top frame is formed by splicing two first top rods and two second top rods together, and the position of the first top rod corresponds to the position of the first bottom rod, the position of the second top rod corresponds to the position of the second bottom rod, and the position and number of the locking members correspond to the locking holes and fixing holes;

[0018] The locking component is connected to the top frame with a straight edge, and the top of the straight edge is connected to an outwardly inclined bevel. A through splicing hole is also provided inside the bevel. The through post and the boss are inserted into the splicing hole, the locking hole, and the fixing hole, and the boss rotates and buckles inward into the locking hole and the fixing hole.

[0019] By setting a locking component, the locking component is designed with a straight edge and a beveled edge. The straight edge is used to connect with the top frame, and the beveled edge is inclined outward to assist in guidance during locking and stacking, thereby improving the locking strength and stacking efficiency.

[0020] Preferably, a reinforcing steel is connected between the central frame and the bottom and top frames, and the reinforcing steel is located at the center of the four sides of the upper and lower end faces of the central frame.

[0021] The reinforced steel structure improves the overall strength of the material rack unit.

[0022] Preferably, the inner sides of the top corners of the central frame, bottom frame, and top frame are all provided with internal supports.

[0023] The internal bracing improves the stability of the central frame, bottom frame, and top frame, thereby increasing the strength of individual frame units.

[0024] Preferably, the diameter of the boss and the through post is smaller than the diameter of the splicing hole, and the length of the boss is greater than the diameter of the splicing hole.

[0025] The diameter of the boss and the through post is smaller than the diameter of the splicing hole, ensuring that the locking mechanism can be inserted into the splicing hole to achieve locking. The length of the boss is greater than the diameter of the splicing hole, which ensures that the boss can be locked after the splicing hole is connected.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] By incorporating a locking mechanism and a rack unit, two rack units can be stacked on top of each other and locked in place by the locking mechanism. The locking mechanism automatically locks the racks without requiring additional operation, greatly improving its practicality. At the same time, each rack unit has an outwardly tilting locking component at its top. This locking component serves two purposes: firstly, it works in conjunction with the locking mechanism for locking and securing the racks, and secondly, it assists in positioning the racks during stacking, significantly improving operational efficiency.

[0034] like Figures 1-4 As shown, this utility model provides a stackable self-locking material frame, including a material rack unit 1, wherein there are two material rack units 1, and the two material rack units 1 are stacked.

[0035] Two stacked rack units 1 are locked together by several connecting and locking components 2;

[0036] The connecting locking assembly 2 includes a pin 18 and a limiting seat 17 coaxially connected to one end of the pin 18. The other end of the pin 18 is provided with a switching groove 19, and a locking mechanism is rotatably connected inside the switching groove 19.

[0037] The locking mechanism includes a connecting piece 20, a boss 22, and a through post 21. The connecting piece 20 is inserted into the switching interior. A through hole 16 is provided through the connecting piece 20 and the switching groove 19. The through post 21 is installed in the through hole 16 inside the switching groove 19. The connecting piece 20 is rotatably connected to the outside of the through post 21 through the through hole 16. The end of the connecting piece 20 away from the switching groove 19 is also connected to the boss 22.

[0038] The material rack unit 1 includes a central frame 12, a bottom frame, and a top frame. The bottom frame is formed by splicing two first bottom rods 3 and two second bottom rods 4. The two first bottom rods 3 and two second bottom rods 4 are arranged in a mirror symmetrical manner. The bottom frame, the central frame 12, and the top frame are stacked sequentially from low to high. The upper and lower end faces of the central frame 12 are provided with a number of support columns 7, which are connected to the bottom frame and the top frame respectively through the number of support columns 7 on the upper and lower end faces.

[0039] The second bottom rod 4 has a sealing plate 5 installed inside. The sealing plate 5 has fixing holes 6 symmetrically arranged at both ends. The first bottom rod 3 also has locking holes 8 symmetrically arranged at both ends. The top frame is provided with locking parts 14 around its perimeter. The bottom frame is also provided with bottom supports evenly and crosswise on its inner sides.

[0040] When the material rack units 1 are stacked, the bottom frame and the top frame of one material rack unit 1 are stacked and connected, and the locking member 14 corresponds to the locking hole 8 and the fixing hole 6. The locking mechanism passes through the locking member 14, the locking hole 8 and the fixing hole 6 to lock.

[0041] Furthermore, the top frame is formed by splicing two first top rods 11 and two second top rods 15 together, and the position of the first top rod 11 corresponds to the position of the first bottom rod 3, the position of the second top rod 15 corresponds to the position of the second bottom rod 4, and the position and number of the locking member 14 correspond to the locking hole 8 and the fixing hole 6.

[0042] The locking member 14 is connected to the top frame with a straight edge, and the top of the straight edge is connected to an outwardly inclined bevel. The bevel is also provided with a through splicing hole 13. The through post 21 and the protrusion 22 are inserted into the splicing hole 13, the locking hole 8, and the fixing hole 6, and the protrusion 22 rotates and buckles inward into the locking hole 8 and the fixing hole 6.

[0043] In use, one rack unit 1 is stacked on top of another rack unit 1. When stacking, the bottom frame on top is installed on top of the other rack unit 1. At this time, the position of the locking member 14 corresponds to the locking hole 8 and the fixing hole 6. The part of the locking member 14 that connects to the top frame is a straight edge, and the top of the straight edge is connected to an outwardly inclined bevel. The straight edge is used to connect to the top frame, and the outwardly inclined bevel is used to assist in the guidance during locking and stacking, so that the bottom frame can be dropped into the top frame. At the same time, a through splicing hole 13 is also provided inside the bevel. At this time, the connecting locking component 2 can be inserted into the splicing hole 13, corresponding to the locking hole 8 and the fixing hole 6.

[0044] Subsequently, the locking mechanism inside the connecting locking assembly 2 operates, and the boss 22 and the connecting piece 20 rotate along the through post 21 and fall automatically. The boss 22 and the pin 18 form a right angle. At this time, the boss 22 can be locked with the inside of the locking hole 8 and the fixing hole 6, thus achieving self-locking.

[0045] Furthermore, the diameter of the protrusion 22 and the through post 21 is smaller than the diameter of the splicing hole 13, and the length of the protrusion 22 is greater than the diameter of the splicing hole 13.

[0046] The diameters of the boss 22 and the through post 21 are smaller than the diameter of the splicing hole 13, ensuring that the locking mechanism can be inserted into the splicing hole 13 to achieve locking. The length of the boss 22 is greater than the diameter of the splicing hole 13, which ensures that the boss 22 can be locked after connecting to the splicing hole 13.

[0047] Furthermore, preferably, a reinforcing steel 9 is connected between the central frame 12 and the bottom frame and the top frame, and the reinforcing steel 9 is located at the center of the four sides of the upper and lower end faces of the central frame 12.

[0048] Furthermore, the inner sides of the top corners of the central frame 12, the bottom frame, and the top frame are all provided with inner supports 10.

[0049] A reinforcing steel 9 is also connected between the central frame 12 and the bottom and top frames. The reinforcing steel 9 improves the strength of the material rack unit 1, and the internal support 10 improves the stability of the central frame 12, the bottom frame and the top frame, thereby increasing the strength of a single material rack unit 1.
