Description

Technical Field

[0001] The utility model relates to the technical field of bracket anti-loosening, in particular to a bracket anti-loosening combined component and a floodlight thereof. Background Art

[0002] A floodlight is a lamp that provides a higher illuminance on a designated illuminated surface than the surrounding environment. Also known as a spotlight, it can typically be aimed in any direction and is designed to be unaffected by climatic conditions. It is primarily used in large-scale mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds.

[0003] During the installation of floodlights, in order to prevent the aiming of the lamps from failing, serrated washers are usually used as anti-loosening components at the connection between the bracket and the lamp body. For example, the prior art has proposed a "floodlight anti-loosening structure" (Chinese patent application number: 202320699201.X), which mainly fixes the serrated locking washer on the bracket so that the serrations of the locking washer are embedded in the surface material of the lamp housing to form a barrier to strengthen the stability of the bracket.

[0004] Although the serrated gasket in this solution is fixed on the bracket and is not easy to scratch the bracket, there are still some defects. For example, each time the serrated gasket rubs against the lamp housing, a certain impact force will always be generated, so that the back of the serrated gasket will produce a slight friction with the bracket. However, the bracket of the existing floodlight usually adopts an iron spraying process. Therefore, after long-term use, the serrated gasket will inevitably wear the surface coating of the bracket, causing the hidden danger of rust.

[0005] At the same time, since the serrated gasket is installed between the bracket and the lamp housing, and it is small and thin, it is not easy to place during assembly. In addition, the serrated gasket is generally made of stainless steel and the bracket is made of iron. The friction between the two is not as good as that between the lamp housing (aluminum) and the serrated gasket, so it is often easy to cause locking failure. Utility Model Content

[0006] Therefore, the main purpose of the present invention is to provide a bracket anti-loosening combined component and a floodlight thereof, so as to solve the problems mentioned in the background technology.

[0007] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a bracket anti-loosening combination component is provided, which includes: a gasket seat, a serrated gasket, and a bracket, wherein the gasket seat is fixed at the rotating end of the bracket, the gasket seat is provided with a gasket groove, the serrated gasket is placed in the gasket groove, and the center of the gasket groove and the serrated gasket is provided with an axial hole to pass through the axial hole at the rotating end of the bracket, so that the bolt can pass through and be connected to the lamp housing axis, and the teeth of the serrated gasket can be abutted against the lamp housing.

[0008] Preferably, a blocking member is arranged around the central axis hole in the gasket groove, and the serrated gasket is at least partially embedded in the gasket groove, and the blocking member and at least part of the teeth of the serrated gasket are blocked to limit the displacement of the serrated gasket in the gasket groove.

[0009] Preferably, the serrated gasket includes: a gasket ring, teeth, wherein each tooth is arranged on the outer ring of the gasket ring, and each tooth is twisted and tilted so that the two ends of each tooth form upward and downward teeth that extend beyond the plane of the gasket ring.

[0010] Preferably, a support member is provided on at least part of the blocking member in the gasket groove to support the upturned teeth of the tooth plate in the gasket groove.

[0012] Preferably, a fixing ring is provided on the fixing column of the gasket seat, and a ring groove is provided in the fourth connecting hole of the cap. When the fixing column of the gasket seat is inserted into the fourth connecting hole of the cap, the fixing ring is matched with the ring groove.

[0013] Preferably, the bracket anti-loosening combined component further comprises: a connecting belt, wherein the cap and the gasket seat are connected via the connecting belt.

[0014] Preferably, the gasket seat is made of any material selected from the group consisting of plastic, resin, rubber, or composite materials thereof.

[0016] The bracket anti-loosening combination component and the floodlight thereof provided by the utility model are cleverly designed with a sandwich structure to fix the limiting serrated gasket through the gasket seat and the internal barrier, thereby not only separating the serrated gasket from the bracket to ensure that the two do not contact each other, thereby solving the hidden danger of rust caused by slight friction between the two damaging the surface coating of the bracket, but also the serrated gasket after being limited by the gasket seat can be better locked with the lamp housing by friction, and is not prone to locking failure problems, thereby ensuring the locking reliability after the bracket angle is adjusted. In addition, due to the design of the gasket seat, small and thin serrated gaskets can be pre-positioned by the gasket seat during product assembly, which is more convenient for workers to assemble and improve production efficiency.

And one or more of the components in the diagram may be necessary or non-essential, and the relative positional relationship between the components in the above diagram can be adjusted according to actual needs.

[0034] In order to improve the angle adjustment effect of the bracket 3 and avoid direct friction between the serrated gasket 2 and the bracket 3, as shown in FIG. Figures 1 to 9 As shown, the utility model provides a bracket anti-loosening combination component, an example of which includes: a gasket seat 1, a serrated gasket 2, and a bracket 3, wherein the gasket seat 1 is fixed at the rotating end of the bracket 3, the gasket seat 1 is provided with a gasket groove 11, the serrated gasket 2 is placed in the gasket groove 11, and the center of the gasket groove 11 and the serrated gasket 2 is provided with an axial hole to pass through the axial hole at the rotating end of the bracket 3, so that the bolt 4 can penetrate and be axially connected to the lamp housing 5, and the teeth 22 of the serrated gasket 2 can be abutted against the lamp housing 5.

[0035] Specifically, if Figures 1 to 7 As shown, the bracket 3 is provided with a first connecting hole 31 and a fixing hole 32, the gasket seat 1 is provided with a fixing column 12 at the first position, and a gasket groove 11 at the second position, wherein the gasket seat 1 is preferably made of any material selected from plastic, resin, rubber, or a composite material thereof, so as to have a certain lightness and rust and corrosion resistance. A second connecting hole 111 is provided in the center of the gasket groove 11, and a barrier 13 is arranged around it. The serrated gasket 2 is at least partially embedded in the gasket groove 11, and at least one of the barrier 13 and the serrated gasket 2 is inserted into the gasket groove 11. Part of the teeth 22 block each other to limit the displacement of the serrated gasket 2 in the gasket groove 11, and align the third connecting hole 23 on the serrated gasket 2 with the second connecting hole 111, and the teeth 22 of the serrated gasket 2 at least partially extend out of the gasket groove 11, and the gasket seat 1 is matched with the fixing hole 32 of the bracket 3 through the fixing column 12, so that the gasket seat 1 is limitedly connected to the inner side surface of the bracket 3, and the second connecting hole 111 is aligned with the first connecting hole 31, so that the bolt 4 passes through the first, second and third connecting holes 31, 111, 23 and mates with the lamp housing 5.

[0036] Through this arrangement, not only can the serrated gasket 2 and the bracket 3 be separated by the gasket seat 1 to avoid contact between the two, but also when the bolt 4 is locked, the serrated gasket 2 and the bracket 3 will simultaneously clamp the gasket seat 1. In addition, the barrier 13 in the gasket groove 11 can promote a tighter connection between the serrated gasket 2 and the gasket seat 1, thereby preventing the serrated gasket 2 from slipping, thereby improving the stability of the bracket 3 during adjustment to achieve an anti-loosening effect.

[0037] Further, such as Figure 6 As shown, the serrated gasket 2 in this example includes: a gasket ring 21, and tooth pieces 22, wherein each tooth piece 22 is arranged at the outer ring of the gasket ring 21, and each tooth piece 22 is twisted and tilted, so that the two ends of each tooth piece 22 form an upward tooth 24 and a downward tooth 25 that exceeds the plane position of the gasket ring 21, so that the downward tooth 25 can be used to resist the blocking member 13 in the gasket groove 11 to improve the limiting stability. At the same time, the upward tooth 24 can better extend out of the gasket groove 11 to be used to resist the lamp housing 5. In addition, the tooth piece 22 formed in this way has a twisted and tilted surface, so when the upward tooth 24 rotates, the tooth tip is subjected to force and rubs against the lamp housing 5, which is easier to form a grip and less likely to slip.

[0038] Further, such as Figure 4 As shown, in an optional example, in order to strengthen the tooth piece 22 and prevent the upward tooth 24 from being crushed by the lamp housing 5 after the bolt 4 is tightened, a support member 14 may be provided on at least part of the barrier member 13 in the gasket groove 11 to support the upward tooth 24 of the tooth piece 22 in the gasket groove 11, thereby strengthening the pressure resistance of the upward tooth 24 and improving the structural reliability.

[0039] Further, such as Figures 4 and 5 As shown, in order to protect the bolt 4, in an optional embodiment, the bracket anti-loosening assembly component further includes: a cap 6, wherein the cap 6 is provided with a fourth connecting hole 61, and the fixing column 12 of the gasket seat 1 passes through the fixing hole 32 of the bracket 3 and is matched with the fourth connecting hole 61 of the cap 6, so that the cap 6 is fixed to one side of the bracket 3 to cover the head of the bolt 4 to form protection.

[0040] Furthermore, in order to improve the connection stability between the cap 6 and the gasket seat 1, as Figure 5 As shown, in an optional embodiment, a fixing ring 121 is provided on the fixing column 12 of the gasket seat 1, and a ring groove 611 is provided in the fourth connecting hole 61 of the cap 6. When the fixing column 12 of the gasket seat 1 is inserted into the fourth connecting hole 61 of the cap 6, the fixing ring 121 is matched with the ring groove 611, thereby improving the plug-in stability and preventing the cap 6 from being detached.

[0041] Furthermore, in order to facilitate product production and assembly, such as Figures 4 and 5As shown, in an optional embodiment, the bracket anti-loosening combination component further includes: a connecting belt 7, wherein the cap 6 and the gasket seat 1 are connected via the connecting belt 7, so that during the assembly process, the cap 6 and the gasket seat 1 will be associated with each other in a pair and are not easy to disengage, so that after the screws are matched, the cap 6 can be quickly closed to facilitate assembly by workers.

[0042] On the other hand, corresponding to the above examples, the present invention also provides a floodlight, which includes: a light source unit, a lamp housing, and a bracket unit, wherein the light source unit is placed in the lamp housing, and the bracket unit is connected to the lamp housing, wherein the bracket unit adopts the structure of the bracket anti-loosening combination component described in any of the above examples.

[0043] In summary, the bracket anti-loosening combination component and the floodlight thereof provided by the utility model cleverly design a sandwich structure, so as to fix the limiting serrated gasket 2 through the gasket seat 1 and the internal barrier 13, thereby not only separating the serrated gasket 2 from the bracket 3 to ensure that the two do not contact each other, so as to solve the hidden danger of rust caused by slight friction between the two and damage to the surface coating of the bracket 3, but also the serrated gasket 2 after being limited by the gasket seat 1 can be better frictionally locked with the lamp housing 5, and is not prone to locking failure problems, thereby ensuring locking reliability. In addition, due to the design of the gasket seat 1, the small and thin serrated gasket 2 can be pre-positioned by the gasket seat 1 during product assembly, which is more convenient for workers to assemble and improve production efficiency.
