Description

TECHNICAL FIELD

[0001] The present application relates to the field of LED lighting lamps, in particular to a LED mining lamp, an interface, a cover and an auxiliary part. BACKGROUND

[0002] The LED mining lamp (also known as high-bay lamp) is a commonly used lighting lamp in factories, warehouses and other places. In order to be fixed on a building, a hoisting assembly needs to be pre-installed on the lamp. The conventional hoisting assembly includes an interface, a cover and a hollow screw. The lower end of the interface is provided with a cover fixing thread, and the upper end is provided with a rod fixing thread. The worker assembles as follows: after the hollow screw passes through the cover, it is screwed into the cover fixing thread at the lower end of the interface to fix the interface and the cover. The cover is fixedly connected to the lamp body to form a complete lamp. When the customer installs it, the hoisting rod thread is screwed into the rod fixing thread at the upper end of the interface, and the other end of the hoisting rod is fixed to the building.

[0003] This structure has been used for more than ten years, and the industry has not noticed obvious problems, but the present inventor has found that it has three core defects: 1. Not firm: the interface and the cover are fixed by a hollow screw, which is a single-point fixing. During assembly, the interface and the hollow screw are easy to rotate at the same time, i.e. "rotate on the same axis". Moreover, the interface is cylindrical, so it is difficult to clamp with an assembly tool and it is not easy to tighten. Even if it is forcibly tightened, it may still be loose when the customer installs or maintains it; 2. Low assembly efficiency: the worker needs to manually pass the hollow screw through the cover, screw it into the cover fixing thread of the interface for 5 to 10 turns, and then use a tool to tighten it. Manual screwing takes a long time, and manual operation accounts for a high proportion. One worker can only assemble 150 interfaces per hour; 3. High overall cost: (1) The hollow screw structure is complex, large in size and high in manufacturing cost; (2) Low assembly efficiency and high labor cost; (3) The cover fixing thread structure at the lower end of the interface is complex, has many processing procedures, and the interface is high in manufacturing cost.

[0004] In addition, Patent No. CN202020171515.9 discloses an improved scheme: at least two internal threads are provided on the side wall of the interface, which aims to reduce the height of the interface, save materials and reduce the material cost of the interface itself. However, this scheme has inherent defects: in order to provide threads on the side wall, the side wall of the interface needs to be made very thick. Even if M3 small threads are provided, the thickness of the side wall needs to be more than 5 mm, which increases the amount of materials used and makes the cost even higher, which has the opposite effect and does not solve the problem of high overall cost. In addition, Patent No. CN202020171515.9 does not address the problems of "low assembly efficiency and not firm" of the conventional hoisting assembly, nor does it provide any relevant inspiration, so it does not solve these two problems. SUMMARY

[0005] To solve the above problems, the present application provides a LED mining lamp, which makes the lifting assembly achieve the effects of firm fixation, high assembly efficiency and low overall cost.

[0006] Technical solution 1: bottom multi-point screw fixation scheme It comprises: setting at least two cover fixing holes on both sides of the center of the bottom of the interface; setting through holes corresponding to the cover fixing holes on both sides of the center of the top of the cover; and further comprising small screws matched with the cover fixing holes; The assembly method is: inserting the matched small screws through the through holes of the cover and into the cover fixing holes of the bottom of the interface to complete the assembly.

[0007] Beneficial effects 1. Firm fixation: multi-point fixation at the bottom, which can avoid the problem of "continuous rotation" and insecurity in the conventional single-point fixation scheme; 2. High assembly efficiency: the small screws are small in size, and an electric screwdriver with magnetism can be used to suck up the small screws, directly pass them through the through holes of the cover, and screw them into the cover fixing holes of the interface, so that the manual screwing process in the conventional scheme is not needed, and the screwing, tightening and assembly are completed at one time, and usually one worker can assemble 300 interfaces per hour, i.e., high assembly efficiency; 3. Low overall cost: the original cover fixing thread at the lower end of the interface is cancelled, the processing procedure is reduced, and the manufacturing cost of the interface is reduced; the original high-priced hollow screw is replaced by a low-cost small screw, and the screw cost is reduced; due to the high assembly efficiency, the labor cost is reduced; and finally the overall cost of the lifting assembly is reduced.

[0008] Technical solution 2: side ear multi-point screw fixation scheme It comprises: setting at least two side ears on both sides of the center of the lower end of the interface and the outer side of the interface wall, and setting cover fixing holes on the side ears respectively; setting through holes corresponding to the cover fixing holes on both sides of the center of the top of the cover; and further comprising small screws matched with the cover fixing holes; The assembly method is: inserting the matched small screws through the through holes of the cover and into the cover fixing holes of the side ears of the interface to complete the assembly.

[0009] Beneficial effects 1. Firm fixation: two-point fixation of the side ears, which can avoid the problem of "continuous rotation" and insecurity in the conventional single-point fixation scheme; 2. High assembly efficiency: the small screws are small in size, and an electric screwdriver with magnetism can be used to suck up the small screws, directly pass them through the through holes of the cover, and screw them into the cover fixing holes of the interface, so that the manual screwing process in the conventional scheme is not needed, and the screwing, tightening and assembly are completed at one time, and usually one worker can assemble 300 interfaces per hour; 3. Overall low cost: cancel the original interface lower end cover screw and the material it occupies, reduce the processing procedure, reduce the interface cost; replace the original high-priced hollow screw with a low-cost small screw, reduce the screw cost; due to high assembly efficiency, reduce the labor cost; finally reduce the overall cost of the lifting assembly.

[0010] Technical solution 3: multi-point buckle fixing scheme Comprise: at least 2 buckle pairs (latches / slots) are arranged on the center of both sides of the lower end of the interface and the center of both sides of the top of the cover. Assembly method: align the latches / slots on the interface with the latches / slots on the cover, press until "click", latch into slot, complete assembly. Note: The positions of the latches and the slots can be interchanged without affecting the fixing effect.

[0011] Beneficial effects 1. Firm fixation: multi-point buckle fixation, no "continuous rotation" and unfirmness problems of conventional single-point fixation scheme; 2. High assembly efficiency: no need for manual screwing process of conventional scheme, and no need for any screw fixing process, 1 worker can assemble 500 interfaces per hour; 3. Overall low cost: cancel the original interface lower end cover screw and the material it occupies, reduce the processing procedure, reduce the interface cost; no need for any screw, reduce the screw cost; higher assembly efficiency, further reduce the labor cost; finally reduce the overall cost of the lifting assembly.

[0020] Auxiliary structure embodiment Example 4: Auxiliary structure used in technical solution 1 ( Figure 1 (B) On both sides of the center of the auxiliary component Z's sheet Z1, through holes 111Z and 112Z are provided (corresponding to the cover through holes 111G and 112G and the interface fixing holes 111A and 112A); positioning posts 11Z and 12Z are set on the top of the sheet, and positioning posts 13Z and 14Z are set on the bottom, forming a connection structure; positioning holes 11A and 12A are set on the interface 1A (corresponding to the positioning posts 11Z and 12Z), and positioning holes 13G and 14G are set on the cover G (corresponding to the positioning posts 13Z and 14Z), forming a fixing structure; Assembly method: First, insert the positioning pin into the corresponding positioning hole for pre-fixing; then, screw the small screws M1 and M2 through the cover through hole and the plate through hole into the interface fixing hole to complete the assembly.

[0021] Example 5: Auxiliary structure used in technical solution 2 ( Figure 2 (B) On both sides of the center of the sheet Z1 of the auxiliary component Z, there are through holes 211Z and 212Z (corresponding to the through holes 211G and 212G of the cover); positioning posts 23Z and 24Z are set on the bottom of the sheet, and positioning groove 25Z is set on the top of the sheet, forming a connection structure; positioning holes 23G and 24G are set on the cover G (corresponding to the positioning posts 23Z and 24Z); the lower outer diameter of the interface 1B is adapted to the positioning groove 25Z, thereby forming a fixing structure; Assembly method: First, insert the positioning pin into the positioning hole and insert the lower end of interface 1B into the positioning groove for pre-fixation; then, screw the small screws M1 and M2 through the cover through hole and the plate through hole into the interface side ear fixing hole to complete the assembly. Note: The connection structure and fixing structure are not limited to those described in Examples 4 and 5, and can be any known structure.

[0022] Technical Solution 3 Combined Structure Objective: To make processing easier; to improve safety; Solution: Add a sheet body W, with a latch / slot at the bottom of the sheet body W (the sheet body / latch / slot are all made of insulating material). The top of the sheet body W can be connected to the lower end of the interface body through known methods such as adhesive, snap-fit, and screw fixation to form a combined interface. Effects: The interface body and the latch / slot are processed separately, simplifying the manufacturing process and making it more convenient and easier to process; both the body W and the latch / slot are insulators, so the connection between the interface and the cover is non-conductive, making it safer.

[0023] Example 6: Combined structure (interface latch + cover slot) Figure 4 The latches 311C and 312C are located below the plate body W, and the upper part of the plate body W is fixed to the lower end of the interface body 1C1.

[0024] Example 7: Combined structure (interface slot + cover latch) Figure 5 Card slots 333C and 334C are located below the chip body W, and the upper part of the chip body W is fixed to the lower end of the interface body 1C1.

[0025] Reinforcement and fixation: Figure 6 The thickened card slots 333CH and 334CH have card slot through holes 341D and 342D at their lower center. The corresponding positions of the interface body 1C1 have fixing holes 341K and 342K. The screw M is screwed into the interface fixing hole through the card slot through hole, which not only fixes the interface body and the plate, but also enhances the strength of the card slot.

[0026] Assembly guide structure: Figure 7 China A Figure 4 , Figure 5 , Figure 6 Positioning posts 31W and 32W (higher than the latch / slot) are added below the body W. Positioning holes 31G and 32G are opened at corresponding positions on both sides of the center of the cover G. During assembly, the positioning posts guide first, so that the latch and the slot are quickly aligned, thus fixing the interface 1C to the cover G.

[0027] Multifunctional design of the positioning column: Figure 1 C, Figure 2 C, Figure 7 China B Positioning posts 13Z and 14Z in technical solution 1; positioning posts 23Z and 24Z in technical solution 2; and positioning posts 31W and 32W in technical solution 3 all have fixing plate holes (131Z, 141Z; 231Z, 241Z; 311W, 322W) at their center. This design enables all positioning posts to have dual functions of "assembly guidance / pre-fixation" and "circuit board fixing". Among them, the positioning post of technical solution 3 can simultaneously adapt to the assembly guidance requirements of its two combination structures (interface tongue + cover slot, interface slot + cover tongue). This design effectively improves component integration and assembly efficiency.
