Abstract

The present invention provides a plastic rack, comprising: a support base, a tool rack, and a supporting part. When the plastic rack is folded, the tool rack and the supporting part are received on the support base; and when the plastic rack is unfolded, the tool rack and the supporting part form a triangular support on the support base. When the plastic rack is in a folded state, both the tool rack and the supporting part can be received on the support base, thereby facilitating transportation of the plastic rack. When the plastic rack needs to be used, the tool rack and the support base can be connected by means of hooks, so that the plastic rack is unfolded, and the tool rack and the supporting part form a triangular support structure on the support base. Since a triangular structure has stability, the unfolded plastic rack also has good stability, and the tool rack is not prone to loosening or collapse when tools are placed thereon.

Description

A plastic frame Technical Field

[0001] This invention relates to the field of storage tools technology, and more specifically, to a plastic frame. Background Technology

[0002] Commonly used multi-sized hand tools typically require storage containers, such as plastic racks, for neat and orderly organization, facilitating better sales display and centralized storage. During the sale, use, and storage of tools, plastic racks have varying placement requirements; sometimes they need to be placed horizontally, sometimes vertically, and sometimes at an angle. Furthermore, due to the different sizes of various tools, storage space cannot be adjusted according to tool size. Additionally, commonly used plastic racks are bulky, making packaging inconvenient and transportation costs high. Summary of the Invention

[0003] This invention overcomes the following shortcomings of existing storage devices: (1) the volume cannot be adjusted during transportation, resulting in increased transportation costs; (2) the storage space cannot be adjusted according to the size of the tools; (3) the placement angle cannot be flexibly adjusted according to different application scenarios; and provides a plastic frame with the following advantages: (1) it can be folded during transportation, reducing the volume during transportation, lowering transportation costs, and facilitating assembly; (2) the storage space corresponding to different tools can be adjusted according to different tool sizes; and (3) the placement angle can be adjusted according to different scenarios.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a plastic frame, comprising: a support base, a tool rack, and a support part; when the plastic frame is folded, the tool rack and the support part are stored in the support base; when the plastic frame is unfolded, the tool rack and the support part form a triangular support on the support base.

[0005] In this invention, when the plastic frame is folded, both the tool holder and the support can be stored on the support base, facilitating the transport of the plastic frame. When the plastic frame is needed, the tool holder can be connected to the support base via hooks, allowing the plastic frame to unfold. The tool holder and the support base form a triangular support structure on the support base. Triangles provide stability, therefore, the unfolded plastic frame also has good stability, preventing the tool holder from easily loosening or collapsing when tools are placed on it. Furthermore, because the tool holder and the support base are connected via hooks, unfolding the plastic frame is very quick and convenient.

[0006] Preferably, the two sides of the support are hinged to the tool rack and the support base, respectively.

[0007] The tool rack, support, and bracket are connected to each other by hinges to form a whole, which facilitates the overall assembly; at the same time, no parts will be lost during transportation and use.

[0008] Preferably, the tool holder has at least one first hook on the side away from the support, and the support base has at least one first slot that mates with the first hook.

[0009] The first slot and the first groove work together to allow the tool rack to be stably connected to the bracket. When the bracket is hung on the wall, it can improve the stability between the tool rack and the bracket.

[0010] Preferably, the first slot has a first protrusion, and the first hook has a second slot that mates with the first protrusion.

[0011] When the first hook engages with the first slot, the first protrusion passes precisely into the second slot, providing a secondary fixing effect and effectively preventing the first hook from detaching from the first slot.

[0012] Preferably, at least one third slot is provided on the side of the tool holder away from the support, and a second protrusion is provided on the bracket to cooperate with the third slot. When the plastic frame is unfolded, the second protrusion is inserted into the third slot.

[0013] The second protrusion and the third slot can be set to an interference fit, thereby improving the stability of the connection between the tool holder and the support base.

[0014] Preferably, the tool holder is provided with sliding shafts at both ends on the side away from the support, and sliding grooves are provided on both sides of the support base along its width direction, with at least one positioning part that cooperates with the sliding shaft in the sliding groove.

[0015] The tool holder and the support base are connected by a sliding shaft and a sliding groove. The sliding shaft can slide within the sliding groove, and through the cooperation of the positioning part, the sliding shaft can be positioned within the sliding groove. The unfolded angle of the tool holder can be adjusted according to usage needs. Furthermore, during use, the sliding shaft always slides within the sliding groove; the tool holder and support part can be simply pulled apart for easy installation.

[0016] Preferably, the positioning part includes at least one fourth slot disposed on the side wall of the slide, the fourth slots being evenly distributed on the side of the slide near the tool holder.

[0017] The slide shaft can be fixed in the fourth slot by cooperating with it in different positions, thereby fixing the tool holder.

[0018] Preferably, several fourth slots are evenly distributed on both sides of the slide.

[0019] When the bracket is suspended on the wall, the sliding shaft abuts against the fourth slot on one side; when the bracket is laid flat, the sliding shaft abuts against the fourth slot on the side away from the tool rack.

[0020] Preferably, the support is provided with a stop, which has a used state and a non-used state relative to the support.

[0021] The stop is installed on the support and is perpendicular to the support. Adjacent stops cooperate to form a compartment, and tools can be placed in the compartment in an orderly manner.

[0022] Preferably, the stop is a detachable connecting support, and the stop is provided with a mounting part that mates with the support.

[0023] When the plastic frame is unfolded, the stops can be installed on the support, making the stops perpendicular to the support. Adjacent stops cooperate to form a compartment, and tools are placed in the compartment in an orderly manner. When the plastic frame is folded, the stops can be removed, laid flat, and the stops, tool rack, and support are stored together in the bracket.

[0024] Preferably, the support portion is provided with a plurality of first and second latches, which are distributed on both sides of the support portion in the width direction; the stop is provided with two mounting portions, which are respectively engaged with the first and second latches.

[0025] The mounting section connects to the first and second bayonets via snap-fit ​​mechanisms, facilitating the disassembly and assembly of the stop. When the stop is needed, the mounting portion on the stop can be directly inserted into the first and second bayonets to install the stop on the support. When the plastic frame needs to be transported, the stop is removed, and the stop, tool rack, and support are laid flat together on the bracket base. Furthermore, by disassembling and assembling the stop, the spacing between adjacent stops can be adjusted to accommodate the space requirements of different tools.

[0026] Preferably, stop grooves are provided on both sides of the support in the width direction, and the stop grooves are provided along the length direction of the support; the stop is provided with two mounting parts, which are slidably disposed in the stop grooves, and the mounting parts are interference fit with the stop grooves.

[0027] The mounting section can slide within the stop groove, thereby adjusting the distance between adjacent stops as needed. This allows the distance between adjacent stops to be adjusted according to the size of the tool, making it suitable for the space required by different tools.

[0028] Preferably, the support includes at least one support plate arranged along the length of the tool rack, with both ends of the support plate being hinged to the tool rack and the support base, respectively.

[0029] The support plate provides stable support for the tool rack and has a simple structure.

[0030] Preferably, there are two support plates, which are supported at both ends of the tool holder along its length.

[0031] The two support plates provide stable support for the tool rack. The area between the two support plates prevents interference between the tool and the support when the tool is placed on the tool rack.

[0032] Preferably, the tool holder has several tool holes, and the support has clearance holes that mate with the tool holes.

[0033] When a tool is placed in the tool hole, the clearance hole can prevent interference between the tool and the support.

[0034] Preferably, the edge of the support base is provided with an edge protrusion, and when the plastic frame is in the folded state, the tool rack and support are stored in the space enclosed by the edge protrusion.

[0035] The tool rack and support can be stored inside the bracket, which reduces the size of the plastic frame during transportation and makes it easier to transport.

[0036] Compared with the prior art, the beneficial effects of the present invention are: (1) When the plastic frame is in a folded state, both the tool rack and the support can be stored on the support base, thus facilitating the transportation of the plastic frame. When the plastic frame needs to be used, the tool rack and the support base can be connected by hooks, so that the plastic frame can be unfolded. The tool rack and the support base form a triangular support structure on the support base. Triangles have stability, so the unfolded plastic frame also has good stability. The tool rack is not easy to loosen or collapse when placing tools. In addition, since the tool rack and the support base are connected by hooks, it is very quick and convenient to unfold the plastic frame; (2) The tool rack and the support base are connected by sliding shafts and sliding grooves, which is not only very convenient to unfold the plastic frame, but also allows for selection of the fourth slot at different positions according to the needs of the tool rack unfolding angle; (3) The mounting part can slide in the stop slot, thereby adjusting the distance between adjacent stops 4 as needed, and thus adjusting the distance between adjacent stops according to the size of the tool, making it more practical; (4) The plastic frame in this application can be placed on a flat surface or hung on a wall according to actual use needs; the unfolding angle of the tool rack can also be adjusted; it can adapt to the use needs of different scenarios.

[0053] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Embodiment 1: Referring to Figures 1 to 7, a plastic frame includes: a support base 1, a tool rack 2 and a support part 3; when the plastic frame is folded, the tool rack 2 and the support part 3 are stored in the support base 1; when the plastic frame is unfolded, the tool rack 2 and the support part 3 form a triangular support on the support base 1.

[0054] In this embodiment, the tool holder 2, the support base 1, and the support part 3 are all plate-shaped components. The tool holder 2 has several tool holes 21, which can be of various shapes, such as cross-shaped, circular, or gourd-shaped, to accommodate the placement of different tools. The support part 3 has clearance holes 31 that mate with the tool holes 21. When a tool is placed in the tool hole 21, the clearance holes 31 prevent interference between the tool and the support part 3.

[0055] An edge protrusion 11 is provided on the edge of the support base 1. When the plastic frame is in the folded state, the tool rack 2 and the support part 3 are stored in the space enclosed by the edge protrusion 11. Both the tool rack 2 and the support part 3 can be stored in the support base 1, which can reduce the volume of the plastic frame when transporting it, making the transport of the plastic frame more convenient.

[0056] The two sides of the support part 3 are hinged to the tool rack 2 and the support base 1, respectively; the support part 3 and the support base 1 are rotatably connected by the first rotating shaft 32, and the support part 3 and the tool rack 2 are rotatably connected by the second rotating shaft 33. The tool rack 2, the support part 3 and the support base 1 are connected to each other by hinges to form a whole, which facilitates the assembly of the whole; at the same time, no parts will be lost during transportation and use.

[0057] In one embodiment, one side of the tool holder 2 is hinged to the support 3, and the other side of the tool holder 2 is connected to the support base 1 by means of a hook.

[0058] Specifically, a plurality of first hooks 22 are provided on the side of the tool rack 2 away from the support 3, and a first slot 12 that mates with the first hooks 22 is provided on the support base 1. In this embodiment, there are two first hooks 22, which are symmetrically distributed at both ends of the tool rack 2 along its length. Correspondingly, the first slots 12 are also symmetrically distributed at both ends of the support base 1 along its length. With the two first hooks 22 mate with the first slots 12, the tool rack 2 can be stably connected to the support base 1, and when the support base 1 is hung on the wall, the stability between the tool rack 2 and the support base 1 can be improved.

[0059] In one embodiment, to further improve the stability of the first hook 22 after it engages with the first slot 12, a first protrusion 121 is provided on the first slot 12, and a second slot 221 that engages with the first protrusion 121 is provided on the first hook 22.

[0060] When the first hook 22 engages with the first slot 12, the first protrusion 121 passes through the second slot 221, which serves as a secondary fixation and effectively prevents the first hook 22 from detaching from the first slot 12.

[0061] In one embodiment, a plurality of third slots 23 are provided on the other side of the tool holder 2 away from the support part 3, and a second protrusion 13 is provided on the bracket 1 to cooperate with the third slots 23. When unfolded, the second protrusion 13 is inserted into the third slots 23.

[0062] Specifically, in this embodiment, there are two third slots 23, which are located at the middle of the length of the tool holder 2, that is, between the two first hooks 22. The cooperation between the second protrusion 13 and the third slot 23 can improve the stability of the connection between the tool holder 2 and the support base 1. The second protrusion 13 and the third slot 23 can be configured as an interference fit, thereby improving the stability of the connection between the tool holder 2 and the support base 1.

[0063] In this invention, when the plastic frame is in a folded state (as shown in Figure 3), both the tool holder 2 and the support part can be stored on the support base 1, thus facilitating the transportation of the plastic frame. When the plastic frame is needed, the tool holder 2 can be connected to the support base 1 via hooks, allowing the plastic frame to unfold (as shown in Figure 1). The tool holder 2 and the support part form a triangular support structure on the support base 1. Triangles are stable, therefore, the unfolded plastic frame also has good stability, and the tool holder 2 is not prone to loosening or collapsing when tools are placed on it. In addition, since the tool holder 2 and the support base 1 are connected via hooks, unfolding the plastic frame is very quick and convenient.

[0064] Example 2: Referring to Figures 10 to 12, a plastic frame includes: a support base 1, a tool rack 2, and a support part 3; when the plastic frame is folded, the tool rack 2 and the support part 3 are stored in the support base 1; when the plastic frame is unfolded, the tool rack 2 and the support part 3 form a triangular support on the support base 1.

[0065] In this embodiment, the tool holder 2, the support base 1, and the support part 3 are all plate-shaped components. The tool holder 2 has several tool holes 21, which can be of various shapes, such as cross-shaped, circular, or gourd-shaped, to accommodate the placement of different tools. The support part 3 has clearance holes 31 that mate with the tool holes 21. When a tool is placed in the tool hole 21, the clearance holes 31 prevent interference between the tool and the support part 3.

[0066] An edge protrusion 11 is provided on the edge of the support base 1. When the plastic frame is in the folded state, the tool rack 2 and the support part are stored in the space enclosed by the edge protrusion 11. Both the tool rack 2 and the support part 3 can be stored in the support base 1, which can reduce the volume of the plastic frame when transporting it, making the transport of the plastic frame more convenient.

[0067] The two sides of the support part 3 are hinged to the tool rack 2 and the support base 1, respectively; the support part 3 and the support base 1 are rotatably connected by the first rotating shaft 32, and the support part 3 and the tool rack 2 are rotatably connected by the second rotating shaft 33. The tool rack 2, the support part 3 and the support base 1 are connected to each other by hinges to form a whole, which facilitates the assembly of the whole; at the same time, no parts will be lost during transportation and use.

[0068] This embodiment is similar in structure to Embodiment 1, except that the tool holder 2 has sliding shafts 24 at both ends on the side away from the support 3, and sliding grooves 14 are provided on both sides of the support base 1 along its width direction. Several positioning parts that cooperate with the sliding shafts 24 are provided within the sliding grooves 14. It should be noted that "width direction" refers to the direction along the shorter side of the support base 1, as shown in Figure 10 (W1 direction); "length direction" refers to the direction along the longer side of the support base 1, as shown in Figure 10 (L1 direction).

[0069] In this embodiment, the tool holder 2 and the support base 1 are connected by a sliding shaft 24 and a sliding groove 14. The sliding shaft 24 can slide within the sliding groove 14, and through the cooperation of the positioning part with the sliding shaft 24, the sliding shaft 24 can be positioned within the sliding groove 14. The unfolding angle of the tool holder 2 can be adjusted according to the needs of use. Furthermore, during use, the sliding shaft 24 always slides within the sliding groove 14. When in use, simply pull apart the tool holder 2 and the support part 3, and the sliding shaft 24 on the tool holder 2 will slide along the sliding groove 14, allowing the support part 3 and the tool holder 2 to unfold, which is convenient for installation.

[0070] In one embodiment, the positioning part includes a plurality of fourth slots 141 disposed on the side wall of the slide 14, and the fourth slots 141 are evenly distributed on the side of the slide 14 near the tool holder 2.

[0071] In use, the slide shaft 24 can be fixed in the fourth slot 141 by cooperating with it in different positions, thereby fixing the tool holder 2. In addition, in order to improve the stability of the slide shaft 24 fixed in the fourth slot 141, the fourth slot 141 can be set in a barb shape to prevent the slide shaft 24 from easily detaching from the fourth slot 141.

[0072] In one embodiment, a plurality of fourth slots 141 are evenly distributed on both sides of the slide groove 14. This allows the slide shaft 24 to abut against the fourth slot 141 on the side away from the tool holder 2 when the support base 1 is laid flat.

[0073] In one embodiment, the positioning part may also have a through hole at the bottom of the slide groove 14 and a shaft hole at the end of the slide shaft 24. When the plastic frame is unfolded, a pin or screw is inserted into the shaft hole through the through hole to fix the slide shaft 24. Of course, it can also be used in conjunction with the fourth slot 141 to make the slide shaft 24 more stably fixed in the fourth slot 141.

[0074] In this invention, when the plastic frame is folded, both the tool holder 2 and the support can be stored on the bracket 1, facilitating the transport of the plastic frame. When the plastic frame is needed, the tool holder 2 can be pulled out, allowing the sliding shaft 24 to slide within the sliding groove 14. The sliding shaft 24 is fixed within the fourth slot 141 by cooperating with it, thus securing the tool holder 2 and allowing the plastic frame to be unfolded, making it very convenient to use. The tool holder 2 and the support form a triangular support structure on the bracket 1. Triangles have stability, therefore, the unfolded plastic frame also has good stability, and the tool holder 2 is not prone to loosening or collapsing when tools are placed on it. In addition, since the tool holder 2 and the bracket 1 are connected by the sliding shaft 24 and the sliding groove 14, it is not only very convenient to unfold the plastic frame, but also allows for selection of the unfolding angle of the tool holder 2, cooperating with the fourth slot 141 at different positions.

[0075] Example 3: Referring to Figures 1 to 7, this example is similar in structure to Example 1 or Example 2, except that the support portion 3 is provided with several stops 4, which have active and inactive states relative to the support portion 3. In the active state, the stops 4 are perpendicular to the support portion 3 or at a certain angle; in the inactive state, the stops 4 lie flat on the support portion 3. The surface of the stops 4 is provided with multiple reinforcing grooves 46, which enhance the overall strength of the stops 4. In this example, the reinforcing grooves 46 are circular grooves.

[0076] A mounting part 41 is provided on the stop 4, which is detachably connected to the support part 3. The stop 4 is detachably mounted to the support part 3 via the mounting part 41. The stop 4 can be installed on the support part 3 as needed. For example, when the plastic frame is unfolded, the stop 4 can be installed on the support part 3, so that the stop 4 is perpendicular to the support part 3 or at a certain angle, and adjacent stops 4 cooperate to form a compartment, in which tools can be placed in an orderly manner. When the plastic frame is in a folded state, the stop 4 can be disassembled, the stop 4 can be laid flat, and the stop 4, tool rack 2, and support part 3 are stored together in the bracket base 1.

[0077] Additionally, as shown in Figure 7, when the plastic frame is in a folded state, the stop 4 can be installed together with the support 3. The stop 4 is perpendicular to the support 3 or forms a certain angle with it, and a partition chamber is formed between adjacent stop 4s. Pliers (such as pliers) can be placed in the partition chamber. In this state, the bracket 1 does not need to be hung on the wall; it can be used simply by placing it on a flat surface. Therefore, the plastic frame in this embodiment can adapt to various usage needs.

[0078] In one embodiment, the support portion 3 is provided with a plurality of first latches 34 and second latches 35, which are distributed on both sides of the support portion 3 in the width direction; the stop member 4 is provided with two mounting portions 41, which respectively engage with the first latches 34 and the second latches 35. It should be noted that "width direction" refers to the direction of the shorter side of the support portion 3, as shown in the W2 direction in Figure 4; "length direction" refers to the direction of the longer side of the support portion 3, as shown in the L2 direction in Figure 4.

[0079] The mounting part 41 is connected to the first bayonet 34 and the second bayonet 35 by a snap-fit ​​mechanism, which facilitates the disassembly and assembly of the stop 4. When the stop 4 is needed, the mounting part 41 on the stop 4 can be directly inserted into the first bayonet 34 and the second bayonet 35 to install the stop 4 on the support part 3; when the plastic frame needs to be transported, the stop 4 is removed and the stop 4, tool rack 2 and support part 3 are laid flat together on the bracket base 1.

[0080] Example 4: Referring to Figures 8 and 9, this example is similar in structure to Example 3, except that in Example 3, although the stop 4 can be detached and stored in the support base 1 along with the tool holder 2 and the support 3, the spacing between adjacent stop 4 cannot be adjusted when the plastic frame is unfolded, thus failing to meet the needs of different tools. Therefore, this example improves upon this problem by allowing the spacing between adjacent stop 4 to be adjusted according to the width and size of the tool.

[0081] Specifically, stop grooves 36 are provided on both sides of the support part 3 in the width direction, and the stop grooves 36 are provided along the length direction of the support part 3; the stop 4 is provided with two mounting parts 41, which are slidably disposed in the stop grooves 36, and the mounting parts 41 are interference-fitted with the stop grooves 36. It should be noted that "width direction" refers to the direction of the shorter side of the support part 3, as shown in the W2 direction in Figure 8; "length direction" refers to the direction of the longer side of the support part 3, as shown in the L2 direction in Figure 8.

[0082] Compared to Embodiment 2, the mounting part 41 in this embodiment can slide within the stop groove 36, thereby adjusting the distance between adjacent stops 4 as needed. This allows the distance between adjacent stops 4 to be adjusted according to the size of the tool to meet the needs of different tools.

[0083] Additionally, one end of the stop slide 36 is open, and a stop 5 is provided at the opening of the stop slide 36. The stop 5 mates with the opening on one side of the stop slide 36; plugs 51 are provided at both ends of the stop 5, and the plugs 51 are interference-fitted with the stop slide 36, inserting into the ends of the stop slide 36 to seal the opening of the stop slide 36. When the plastic frame is folded, the stop 5 is removed, opening the stop slide 36, and the stop 4 is removed from the opening. The stop 4, along with the tool holder 2 and the support part 3, is placed into the bracket base 1. When the stop 4 is to be installed, the stop 5 can be removed, opening the stop slide 36, and the stop 4 can be placed into the stop slide 36 from the opening.

[0084] A force-applying part 52 is provided on the stop 5 at a position corresponding to the plug 51. The force-applying part 52 is provided with several parallel strip-shaped protrusions. The force-applying part 52 can increase the friction between the stop and the fingers, making it easier to remove the stop 5 by hand.

[0085] Example 5: Referring to Figure 13, this example is similar in structure to Example 3 or Example 4, except that the stop 4 is hinged to the support 3. Specifically, the stop 4 is provided with a first shaft 42 and a second shaft 43, which are rotatably mounted on the support 3.

[0086] Using the above method, the stop 4 can be made perpendicular to the support 3 by flipping it over, or the stop 4 can be laid flat on the support 3. This makes it more convenient to use. In addition, when the stop 4 is flipped to a position perpendicular to the support 3, an elastic buckle is provided inside the support 3 to position the first shaft 42 or the second shaft 43. The elastic buckle can ensure that the stop 4 remains perpendicular to the support 3.

[0087] Example 6: Referring to Figure 14, this example is similar to the structure in Example 5, except that the second shaft 43 is a gear shaft 45, and a rack 44 that cooperates with the gear shaft 45 is provided on the support part 3. The gear shafts 45 of several stops 4 are all cooperated with the same rack 44.

[0088] By pulling the rack 44, all the stops 4 can be flipped synchronously, making it convenient for the stops 4 to unfold and fold.

[0089] Example 7: Referring to Figure 15, this example is similar in structure to Example 1 or Example 2, except that the support part 3 includes a plurality of support plates 6 arranged along the length direction of the tool holder 2. The two ends of the plurality of support plates 6 along the length direction are respectively hinged to the tool holder 2 and the support base. There are two support plates 6, which are supported at both ends along the length direction of the tool holder 2.

[0090] One or more support plates 6 can be provided, as shown in Figure 15. In this embodiment, two support plates 6 are provided, which can provide stable support for the tool holder 2. The area between the two support plates 6 can prevent interference between the tool and the support part 3 when the tool is placed on the tool holder 2.
