Description

Technical Field

[0001] The present invention relates to the technical field of chassis equipment, and particularly relates to a snap-fastening assembled chassis. Background Art

[0002] A chassis generally includes a housing, a bracket, a cover plate, etc. The housing is generally made of a combination of steel plate and plastic, with high hardness, and mainly functions to protect the components inside the chassis. A standard chassis is a box with a general and fixed size and compliant with national standards, and is widely used in industries such as computers, instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery.

[0003] Currently, the chassis is generally fixed in the following several ways: The first is to fix it by screws; the second is to fix it by using snap fasteners; the third is to fix it by using rivets or welding. Currently, the chassis mainly has the following problems: Fixing by screws will leave many screw heads on the surface of the chassis cover plate, affecting the appearance of the product. Using snap fasteners is generally a structure adopted by specific chassis and has no universality; while the chassis parts fixed by rivets and welding generally cannot be disassembled. Summary of the Invention

[0004] The purpose of the present invention is to provide a snap-fastening assembled chassis that does not require screws to fix on the surfaces of the chassis cover plate and side plate, and has a simple structure, is firm and durable, and is convenient for disassembly and assembly, and solves at least one of the problems raised in the background art. To achieve the purpose of the present invention, the following technical solutions are adopted:

[0005] A snap-fastening assembled chassis includes a cover plate, a bottom plate, multiple sets of column components, multiple sets of locking components, and multiple side plates. Adjacent two side plates are respectively clamped by a set of column components to form a hollow main frame. A screw hole is provided at the bottom surface of the column component for cooperating with screws to fix the bottom plate. A chute extending along the height direction of the column component is formed on the inner surface of the column component. The locking component includes a locked part and a sliding lock installed in the chute. The sliding lock includes an elastic locking part and a slider detachably connected together. Part of the elastic locking part is exposed outside the chute. One end of the locked part is fixedly connected to the inner surface of the cover plate, and the other end of the locked part is used to insert into the elastic locking part and be clamped by the elastic locking part. A bolt passes through the bottom plate and is connected to a screw hole provided on the bottom surface of the slider.

[0006] Further improvement lies in that the elastic locking part includes multiple elastic blocks, and the multiple elastic blocks enclose to form an insertion hole for the other end of the locked part to insert.

[0007] Further improvement lies in that the outer surfaces of multiple elastic blocks are in a conical structure. When the bottom of the locked part presses the elastic blocks to move inside the sliding groove, the elastic blocks undergo elastic deformation, causing the diameter of the insertion hole to become smaller, thereby clamping the locked part.

[0008] Further improvement lies in that a clamping groove is provided on the locked part, and an inclined surface structure is provided on the inner surface of the elastic block for clamping the clamping groove of the locked part when the diameter of the insertion hole becomes smaller.

[0009] Further improvement lies in that a convex platform is provided on the inner surface of the elastic block, and the top surface of the convex platform contacts the bottom surface of the locked part for supporting the locked part.

[0010] Further improvement lies in that the locked part is a connecting column, one end of the connecting column is fixedly connected to the inner surface of the cover plate by a riveting method, and a clamping groove is provided on the column body of the connecting column.

[0011] Further improvement lies in that the column assembly includes a first connecting plate and a second connecting plate connected to each other, and side plate grooves are respectively provided on the first connecting plate and the second connecting plate for clamping with corresponding side plates.

[0012] Further improvement lies in that the sliding groove is a polygonal sliding groove.

[0013] Further improvement lies in that the bottom opening of the sliding groove is flush with the bottom surface of the column assembly, and there is a certain distance between the top opening of the sliding groove and the top surface of the column assembly.

[0014] Further improvement lies in that feet are provided at the bottom of the chassis.

[0015] Advantages of the present invention:

[0016] In the present invention, the locking assembly is completely hidden inside the chassis, and it is not necessary to use screws separately to fix the cover plate. No screw heads can be seen on the outer surfaces of the cover plate and the side plates, and only screw heads are present at the bottom of the chassis.

[0017] The cover plate of the chassis of the present invention is firmly locked and convenient to disassemble and assemble. When disassembling the cover plate, it does not affect the side plates and the bottom plate, facilitating the installation of internal components in the chassis.

[0018] In the present invention, by setting the elastic locking part and the slider to be detachably connected, in practical applications, different slider lengths and column assembly lengths can be designed to change the height of the chassis, while the elastic locking part can be applied without changing its size, facilitating the secondary development of the product and having strong expandability. In addition, when the elastic locking part is damaged, the elastic locking part can be replaced separately without replacing the slider, saving costs. Description of the Drawings

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The terms "and", "with" as used herein include any and all combinations of one or more of the associated listed items.

[0032] Please refer to the attached Figure 1 - attached Figure 8 In an embodiment of the present invention, a snap - type assembled chassis is proposed, which includes a cover plate 1, a bottom plate 2, multiple groups of column assemblies 3, multiple groups of locking assemblies, and multiple side plates 4. Adjacent two side plates 4 are respectively clamped by a group of column assemblies 3 to form a hollow main frame. A screw hole 5 is provided on the bottom surface of the column assembly 3 for cooperating with a screw 6 to fix the bottom plate 2. A chute 7 extending along the height direction of the column assembly 3 is formed on the inner surface of the column assembly 3. The locking assembly includes a locked part 8 and a sliding lock part installed in the chute 7. The sliding lock part includes an elastic locking part 9 and a slider 21 detachably connected together. A part of the elastic locking part 9 is exposed outside the chute 7. One end of the locked part 8 is fixedly connected to the inner surface of the cover plate 1, and the other end of the locked part 8 is used to be inserted into the elastic locking part 9 and be clamped by the elastic locking part 9. A bolt 10 passes through the bottom plate 2 and is connected to the screw hole 5 provided on the bottom surface of the slider 21.

[0033] Specifically, as Figure 1 、 Figure 2 shown, in this embodiment, the overall structure of the chassis is a cuboid. The number of the column assemblies 3 and the locking assemblies is four groups each, and the number of the side plates 4 is four.

[0034] In addition, the chassis can also be set to other shapes according to the situation, such as a pentagonal chassis. In this case, both the cover plate 1 and the bottom plate 2 are pentagonal structures, and the number of the side plates 4 is five. This embodiment does not make specific limitations.

[0035] Preferably, as Figure 4 、 Figure 6As shown, the elastic locking member 9 and the slider 21 are detachably connected by means of a stud 22 cooperating with a threaded hole 5, that is, the stud 22 is provided at the bottom of the elastic locking member 9, and the threaded hole 5 is provided on the top surface of the slider 21. Before installing the sliding lock member into the chute 7, first connect the elastic locking member 9 and the slider 21 together. In the present invention, by setting the connection between the elastic locking member 9 and the slider 21 to be detachable, in practical applications, different lengths of the slider 21 and the height of the column assembly 3 can be designed to change the height of the chassis, while the elastic locking member 9 can be applied without changing its size, which is convenient for the secondary development of the product and has strong expandability. In addition, when the elastic locking member 9 is damaged, the elastic locking member 9 can be replaced separately without replacing the slider 21, saving costs.

[0036] As Figure 1 , Figure 2 , Figure 3 shown, the locking assembly in this embodiment is completely hidden inside the chassis, and there is no need to separately use screws 6 to fix the cover plate 1. No screw heads can be seen on the outer surfaces of the cover plate 1 and the side plate 4, and only screw heads are present at the bottom of the chassis.

[0037] The cover plate 1 of the chassis in this embodiment is firmly locked and convenient to disassemble and assemble. When disassembling the cover plate 1, it does not affect the side plate 4 and the bottom plate 2, facilitating the installation of internal components in the chassis.

[0038] In this embodiment, as Figure 4 , Figure 7 shown, the elastic locking member 9 includes a plurality of elastic blocks 11, and the plurality of elastic blocks 11 enclose to form an insertion hole 12 for the other end of the locked member 8 to be inserted.

[0039] In this embodiment, the outer surfaces of the plurality of elastic blocks 11 have a conical surface structure 13, and the top of the chute 7 is provided with a shape corresponding to the conical surface structure 13. When the bottom of the locked member 8 presses the elastic blocks 11 to move inward into the chute 7, the elastic blocks 11 undergo elastic deformation to reduce the diameter of the insertion hole 12, thereby clamping the locked member 8.

[0040] A clamping groove 14 is provided on the locked member 8, and an inclined surface structure 15 is provided on the inner surface of the elastic block 11 for clamping the clamping groove 14 of the locked member 8 when the diameter of the insertion hole 12 becomes smaller.

[0041] In this embodiment, a boss 16 is provided on the inner surface of the elastic block 11, and the top surface of the boss 16 contacts the bottom surface of the locked member 8 for supporting the locked member 8.

[0042] When the locked member 8 is inserted into the insertion hole 12 and the bottom surface contacts the top surface of the boss 16, it exerts a pressing force on the boss 16, causing the elastic block 11 to move inward into the chute 7.

[0043] In this embodiment, the fastened member 8 is a connecting column. One end of the connecting column is fixedly connected to the inner surface of the cover plate 1 by riveting, and a clamping groove 14 is provided on the column body of the connecting column.

[0044] In this embodiment, as Figure 5 shown, the column assembly 3 includes a first connecting plate 17 and a second connecting plate 18 which are connected to each other. Side plate grooves 19 are respectively provided on the first connecting plate 17 and the second connecting plate 18 for clamping with the corresponding side plates 4.

[0045] Specifically, the four groups of column assemblies 3 are respectively located at the four corners of the chassis. The column assemblies 3 are made of aluminum alloy profiles. In this embodiment, the thicknesses of the first connecting plate 17 and the second connecting plate 18 are 4 mm, the side plate grooves 19 are 1.7 mm wide and 1.8 mm deep, and the lengths are set according to the actual size of the chassis.

[0046] The first connecting plate 17 and the second connecting plate 18 are perpendicular to each other, that is, a right angle is formed between the first connecting plate 17 and the second connecting plate 18. In addition, if the chassis is not rectangular, the angle between the first connecting plate 17 and the second connecting plate 18 can be changed to adapt to chassis of different shapes, such as a chassis with a triangular or pentagonal cover plate 1 and bottom plate 2.

[0047] In this embodiment, the sliding groove 7 is set as a polygonal sliding groove 7. As Figure 5 shown, in this embodiment, it is a square sliding groove 7. In other embodiments, it can also be a triangular, quadrilateral, pentagonal, etc. The shape of the slider 21 is adapted to the sliding groove 7, so that when the bolt 10 passes through the bottom plate 2 and is connected to the screw hole 5 on the bottom surface of the slider 21, the slider 21 will not rotate.

[0048] In this embodiment, as Figure 6 , Figure 7 , Figure 8 shown, the bottom opening of the sliding groove 7 is flush with the bottom surface of the column assembly 3, and there is a certain distance between the top opening of the sliding groove 7 and the top surface of the column assembly 3. This distance is adapted to the length of the connecting column.

[0049] In this embodiment, as Figure 3 shown, feet 20 are provided at the bottom of the chassis.

[0050] Installation and disassembly process of the present chassis: First, assemble using four sets of column components 3 and four side plates 4. Adjacent side plates 4 are respectively clamped through the side plate slots 19 of a set of column components 3 to form a hollow main frame. Then, install the bottom plate 2 at the bottom opening of the main frame and use screws 6 to pass through the bottom plate 2 and connect with the screw holes 5 on the bottom surface of the column components 3 to fix the bottom plate 2. Next, insert a sliding locking member into the sliding groove 7 of each set of column components 3. After the sliding locking member is inserted into the sliding groove 7, part of the elastic locking member 9 is exposed outside the sliding groove 7. One end of the locked member 8 is pre-fixed to the inner surface of the cover plate 1 by riveting. Then, install the cover plate 1. When installing the cover plate 1, align the other end of the locked member 8 with the insertion hole 12 of the elastic locking member 9 and insert it into the insertion hole 12. Continue to press the cover plate 1 to seal the top opening of the main frame. During the process of pressing the cover plate 1, the other end of the locked member 8 presses the boss 16, causing the elastic locking member 9 to move into the sliding groove 7. At this time, the diameter of the insertion hole 12 becomes smaller, and the elastic locking member 9 forms a clamping effect on the clamping groove 14 on the locked member 8. Then, use bolts 10 to pass through the bottom plate 2 and connect with the screw holes 5 on the bottom surface of the slider 21. At this time, the cover plate 1 is fixed and cannot be disassembled. Thus, the overall installation of the chassis is completed.

[0051] When it is necessary to disassemble the cover plate 1 of the chassis, loosen the bolt 10 on the bottom plate 2 and push the slider 21 upward so that the elastic block 11 extends outside the sliding groove 7 and returns to its original state. At this time, the elastic locking member 9 no longer forms a clamping effect on the clamping groove 14 on the locked member 8, and the locked member 8 can move freely up and down. At this time, just pick up the cover plate 1 directly to complete the disassembly of the cover plate 1.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
