Description

Technical Field

[0001] This utility model relates to a fixing device for a sheet material and its application, and more particularly to a fixing device application that can maintain the integrity of the sheet material. It is provided with a sleeve for assembling at least one or more assembly holes of the sheet material, and a stop member is assembled on one side of the sleeve, so that the fixing device can be quickly positioned at the assembly hole, so as not to affect the surface processing of the sheet material. Background Technology

[0002] When assembling typical panel (panel-to-panel) devices, a locking screw with a knob, collar, and screw is used for fastening. The fastening method involves first fixing the screw and collar to the first panel, then turning the knob to lock the screw into the second panel, and finally using a hand tool to tighten the screw. This fastens the first and second panels into a single unit, which is used for panel-to-panel connections in devices such as telecommunications or network housings, computer or machine tool housings, and other equipment or mechanisms.

[0003] Furthermore, some manufacturers have developed a fixing device that allows for the fixation or separation of boards using hand tools. When the fixing device is released to detach the first board from the second board for removal, the fixing device remains attached to the first board to prevent loss, thus improving ease of use. Figure 7 As shown, the sleeve A has a positioning part A2 below the through hole A1, which is fixed to the plate D by riveting. A receiving groove A11 is provided above the through hole A1. An annular blocking part A3 is provided on the outside of the sleeve A. A rod B2 and a screw part B3 of the fixing element B extending downward from the bottom surface of the head B1 are inserted into the through hole A1 of the sleeve A. An elastic element B4 with two ends abutting against the receiving groove A11 of the through hole A1 and the head B1, respectively, is elastically deformed. An outer sleeve C is attached to the head B1 of the fixing element B. An annular abutment C1 is formed below the receiving space C0 inside the outer sleeve C, which stops the annular blocking part A3, so that the sleeve A, the fixing element B and the outer sleeve C can be in a movable docking state after assembly.

[0004] Furthermore, the plates D used for plate-to-plate connections in casings and outer shells are generally made of metal. To prevent corrosion or deterioration in their environment, a common practice is to bake a paint layer on the outer surface of the plate D, giving it a smooth and aesthetically pleasing appearance and increasing rust resistance. However, the sleeve A of the fixing device is riveted to the hole D1 of the plate D by the positioning part A2, which can scratch the paint layer, cause paint peeling, or even lead to metal corrosion or structural damage, reducing the reliability of the product. Therefore, the positioning part A2 of sleeve A and the hole D1 of plate D can only be installed by assembly. However, the paint layer on one or both sides of plate D will increase its thickness, and cause a gap in plate thickness between plate D and the positioning part A2 of sleeve A, as well as errors in the manufacturing process or assembly. When the fixing element B of the fixing device is locked into the locking hole of another plate, the overall structure will be less stable due to the gap in plate thickness of plate D, and it will not be easy to maintain a stable state. This is the key point that those engaged in this industry urgently need to study and improve.

[0005] Therefore, how to solve the problems and troubles caused by conventional fixing devices easily damaging the surface processing layer of the board during assembly, affecting the structural strength of the board, and causing problems and deficiencies such as poor stability of the fixing device and the board assembly, and easy deformation or cracking of the board, is the direction that relevant manufacturers in this industry are eager to study and improve.

Detailed Implementation

[0027] To achieve the above objectives and effects, the technical means, structure, and implementation methods adopted by this utility model are described in detail below with reference to the accompanying drawings, so as to facilitate a complete understanding.

[0028] Please see Figures 1-6As shown, this utility model provides a fixing device for a sheet material and its application, including a sheet material 1 and at least one fixing device 2 disposed on the sheet material 1, wherein:

[0029] The plate 1 is provided with at least one assembly hole 10, and a limiting area 11 with an enlarged hole diameter is provided on one side of the at least one assembly hole 10. The limiting area 11 is formed by the annular wall surface of at least one or more assembly holes 10 extending outward at an angle, and the inner circular hole 110 is formed by the inclined wall surface of at least one or more limiting areas 11 extending vertically upward.

[0030] The at least one fixing device 2 includes a sleeve 21 and a stop 22 assembled outside the sleeve 21. The sleeve 21 is assembled at at least one or more assembly holes 10 of the plate 1. A limiting section 211 is provided on one side of the sleeve 21 and is assembled at the limiting area 11. The bottom edge 2111 of the limiting section 211 protrudes outside the limiting area 11. An extension section 212 is provided on the side of the sleeve 21 opposite to the limiting section 211, which can also be inserted through the stop 22. After being stamped through the stop 22, it is embedded at the bottom edge 2111, the connecting part 213 and the top edge of the extension section 212 of the limiting section 211, so as to clamp and position it at the top of the extension section 212. This allows the top surface of the sleeve 21 to form a flat state coplanar with the surface of the plate 1, ensuring that the sleeve 21 does not protrude from the surface of the plate 1. The sleeve 21 has an accommodating channel 210 inside for assembling the positioning element 23.

[0031] In the aforementioned plate 1 of this utility model, the inner diameter of at least one assembly hole 10 and the limiting area 11 is larger than the outer diameter of the limiting section 211 and the extension section 212 of the sleeve 21 of at least one fixing device 2. A margin space 12 with a predetermined distance is formed on the relative inner sides of the assembly hole 10, the limiting area 11 and the limiting section 211 and the extension section 212, so that the sleeve 21 can be positioned at the assembly hole 10 of the plate 1 to form an assembly state with adjustable displacement. Furthermore, the limiting area 11 is provided on one side of at least one assembly hole 10 of the plate 1, which is inclined and extended outward. An inner circular hole 110 is formed by the inclined wall surface of at least one or more limiting areas 11 extending vertically upward, so that the side view of at least one assembly hole 10, the limiting area 11 and the inner circular hole 110 can form a Y-shape. Thus, the side view of the limiting section 211 and the extension section 212 outside the sleeve 21 of at least one fixing device 2 can also form a Y-shape.

[0032] Furthermore, in the aforementioned fixing device 2 of this utility model, the outer diameter of the limiting section 211 of the sleeve 21 is larger than the outer diameter of the extension section 212, and a connecting portion 213 is provided between the limiting section 211 and the extension section 212. This is so that the sleeve 21 is embedded in the stop member 22 through a stamping process, allowing the stop member 22 to be embedded and clamped at the connecting portion 213, the bottom edge 2111 of the limiting section 211, and the top edge of the extension section 212 by the impact of the stamping. Therefore, the outer diameter of the stop member 22 is larger than the diameter of at least one assembly hole 10. This allows the stop member 22 to be sleeved on the extension section 212 and fixed at the connecting portion 213, thus embedding at least one sleeve 21 in at least one assembly hole 10 through stamping and forming a limiting effect, making it difficult to loosen or separate. At least one assembly hole 10 provides axial (upper and lower longitudinal) limitation for at least one sleeve 21, but does not provide radial (left and right lateral) limitation; and the receiving channel 210 inside the sleeve 21 of at least one fixing device 2 includes an inner hole 2101 located in the middle section, a receiving hole 2102 located on one side of the inner hole 2101 and inside the limiting section 211, and an inner groove hole 2103 located on the side of the receiving hole 2102 opposite to the inner hole 2101, the inner hole 2101 opposite to the inner groove hole 2103, and a through hole 2104 located inside the extension section 212 on one side of the receiving hole 2102. Then the diameter of the inner hole 2101 is smaller than the diameter of the two receiving holes 2102 and the through hole 2104, while the diameter of the inner groove hole 2103 is larger than the diameter of the receiving hole 2102.

[0033] Furthermore, the at least one fixing device 2 of the present invention is a positioning element 23 that can be assembled in the receiving channel 210 of the sleeve 21. It includes a screw 231 and an elastic body 232 sleeved on the screw 231. The screw 231 is a rod body 2312 with a reduced rod diameter extending from the rod head 2311 side. A threaded section 2313 is provided on the side of the rod body 2312 opposite to the rod head 2311. The outer diameter of the threaded section 2313 on the screw 231 side of the positioning element 23 is larger than the outer diameter of the rod body 2312. A washer 2314 is sleeved on the rod body 2312 and abuts against the threaded section 2313. The outer diameter of the washer 2314 is larger than the diameter of the inner hole 2101 but smaller than the diameter of the through hole 2104.

[0034] In practical application and implementation, the aforementioned fixing device of the plate and its application are designed such that at least one or more mounting holes 10 on the plate 1 can be fitted with at least one or more sleeves 21 of the fixing device 2, that is, the limiting section 211 of at least one or more sleeves 21 is placed in the limiting area 11 of at least one or more mounting holes 10, and the extension section 212 of at least one or more sleeves 21 extends out of the outside of at least one or more mounting holes 10, and the extension section 212 is used to fix the plate 1. Twelve stop members 22 are fitted at each of the following locations: the stop members 22 abut against the surface of the plate 1; after being stamped, the stop members 22 are inserted into the connecting portion 213 between the extension section 212 and the limiting section 211, the bottom edge 2111 of the limiting section 211, and the top edge of the extension section 212 through the inner ring hole 220, to create a clamping and positioning engagement, so that at least one sleeve 21 can be installed at at least one assembly hole 10 to form a limit and to form a coplanar flat state. A predetermined margin space 12 is formed between the positioning areas 11, allowing the limiting section 211 to have appropriate lateral displacement adjustment space margin at the limiting area 11. Then, the screw 231 and elastic body 232 of the positioning element 23 are assembled in the receiving channel 210 of at least one sleeve 21. The rod body 2312 of the screw 231 extends into the inner groove 2103, receiving hole 2102 and inner hole 2101 of the receiving channel 210, so that the threaded section 2313 on one side of the rod body 2312 can pass through the through. At hole 2104, the washer 2314 at the top of threaded section 2313 abuts against the outer side of inner hole 2101 inside through hole 2104, so that the limiting screw 231 is not easy to disengage at receiving channel 210. It can also form a flat state coplanar with the surface of sleeve 21 and plate 1, and will not protrude or be higher than the surface of plate 1. The elastic body 232 sleeved on rod body 2312 abuts against the bottom of rod head 2311 on one side and abuts against the inner wall of receiving hole 2102 on the other side.

[0035] Therefore, when the plate 1 of the present invention is a sleeve 21 for assembling at least one or more fixing devices 2 at at least one or more assembly holes 10, it does not need to be hammered, squeezed or impacted, that is, it will not squeeze or knock the at least one or more assembly holes 10 of the plate 1, and will not cause the plate 1 to deform or crack due to force, nor will it damage the surface processing of the plate 1 (surface treatment, paint layer or mirror treatment, etc.), so as to achieve the purpose of not affecting the surface processing of the plate 1, and avoid the plate 1 from being squeezed, deformed or cracked due to assembly; and the plate 1 can be combined with a frame 13 for assembling electronic devices such as hard disks, removable hard disks, interface cards or multimedia players.

[0036] Furthermore, when the plate 1 of this utility model is to be assembled onto another plate 3, at least one assembly hole 10 of the plate 1 and at least one sleeve 21 of the fixing device 2 can be used to apply force to the rod head 2311 of the positioning element 23 of at least one fixing device 2 at the mating screw hole 30 located on the plate 3. [The rod head 2311 is provided with a slotted hole, a cross slotted hole, an internal hexagonal hole, a polygonal hole, or a star-shaped hole, or an outward convex type. The hand tool is the application of the corresponding slotted screwdriver, cross screwdriver, hex wrench, ratchet wrench, etc.], to compress the rod head 2311 of the positioning element 23 onto the elastic body 232, so as to provide the thread section 231 on the other side. 3. The sleeve 21 extends out of the through hole 2104, and the rod head 2311 of the positioning element 23 sinks into the limiting area 11 of the assembly hole 10. This keeps the surface of the plate 1 flat. The margin space 12 generated by the limiting section 211 of at least one sleeve 21 located in the limiting area 11 of at least one assembly hole 10 can be used to adjust the lateral displacement of the positioning element 23 and facilitate locking and engagement at the mating screw hole 30 of the plate 3. It has a moderate adjustment margin, which makes it easy to assemble the plate 1 onto the outer plate 3. It will not be difficult to assemble due to slight misalignment between the plate 1 and the plate 3, and has good construction quality.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Therefore, any simple modifications and equivalent structural changes made based on the description and drawings of the present utility model should also be included in the patent scope of the present utility model.
