Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a nut mounting and limiting structure, a lens fixing piece provided with the nut mounting and limiting structure, a lamp provided with the lens fixing piece, and a lighting system provided with the lamp. Background Art

[0002] At present, when bolts and nuts are used to fix and connect two or more components, it is usually necessary to hold a screwdriver in one hand to tighten the bolt and a wrench in the other hand to fix or reversely tighten the nut to prevent the nut from rotating during the rotation of the screw; however, this operation method has problems such as inconvenience and low efficiency; in addition, in some structures with limited installation space, it may be impossible to use a wrench to fix or tighten the nut. At this time, the conventional treatment method is to first fix the nut on the component with an adhesive or to injection mold the nut to a preset position through an insert injection molding process to achieve the fixation of the nut during assembly, but the above treatment method is not conducive to improving the assembly efficiency of the product and is not conducive to product maintenance. Summary of the Invention

[0003] The first object of the utility model is to provide a nut installation limiting structure which can prevent the nut from rotating during the assembly process, is easy to maintain and is conducive to improving the assembly efficiency.

[0004] The second object of the present invention is to provide a lens fixing member provided with the above-mentioned nut installation and limiting structure.

[0005] The third object of the present utility model is to provide a lamp provided with the above-mentioned lens fixing member.

[0006] The fourth object of the present utility model is to provide a lighting system equipped with the above-mentioned lamp.

[0007] In order to achieve the first purpose of the utility model, the utility model provides a nut installation limiting structure, which includes a support plate, two transverse limiting ribs and a vertical limiting rib. The support plate is provided with a first through hole passing through itself, and the first through hole is located between the two transverse limiting ribs. The transverse limiting rib is connected to the support plate, and the vertical limiting rib is connected between the two transverse limiting ribs. A clamping position is formed between the vertical limiting rib, the support plate and the two transverse limiting ribs, and the clamping position has an insertion port.

[0008] As can be seen from the above, the nut installation limiting structure can be formed on a part that is fixedly connected by the nut and the bolt. Its clamping position is used to store the nut and limit and fix the nut, thereby preventing the nut and the bolt from rotating during assembly. At the same time, since there is no need to use a wrench to fix or twist the nut during the assembly process, it is less restricted by space and can improve assembly efficiency.

[0009] A further solution is that the nut installation limiting structure includes a bending limiting rib, which is connected between two transverse limiting ribs; along the insertion direction of the clamping position, the bending limiting rib protrudes outward toward the clamping position in a bent shape, and the bending limiting rib is located at the downstream end of the insertion port; the angle at the bending point of the bending limiting rib is between 115° and 125°.

[0010] As can be seen from the above, the bent limiting rib is used to limit the nut in the insertion direction so that the threaded hole of the nut inserted into the clamping position is aligned with the first through hole, ensuring that the bolt can smoothly pass through the threaded hole of the nut after passing through the first through hole of the support plate, thereby improving assembly efficiency.

[0011] A further solution is that the transverse limiting rib extends along the insertion direction, and the insertion direction is roughly perpendicular to the axial direction of the first through hole; two or more tightening reinforcements are formed on the side of the transverse limiting rib facing the other transverse limiting rib, and there is a gap between the two adjacent tightening reinforcements; the tightening reinforcement extends along the axial direction of the first through hole, and the two or more tightening reinforcements are distributed from the bending limiting rib to the insertion port in the insertion direction, or the tightening reinforcement extends along the insertion direction to the bending limiting rib, and the two or more tightening reinforcements are distributed along the axial direction of the first through hole.

[0012] It can be seen from the above that, under the premise of ensuring that the tightening reinforcement and the tightening reinforcement of another transverse limiting reinforcement reliably clamp and fix the nut, the setting of the tightening reinforcement avoids the need for the entire side wall of the nut to contact the entire wall of the transverse limiting reinforcement, effectively reducing the friction force exerted on the nut when it is assembled into the clamping position, thereby facilitating the assembly of the nut into the clamping position.

[0013] A further solution is that there are two vertical limiting ribs, and the two vertical limiting ribs are distributed along the insertion direction of the clamping position. In the insertion direction, the first through hole is located between the two vertical limiting ribs, or in the insertion direction, the vertical limiting rib extends from the downstream end of the transverse limiting rib to the insertion port, and the vertical limiting rib is provided with an avoidance hole passing through itself. In the axial direction of the first through hole, the projection of the first through hole coincides with the projection of the avoidance hole, or the projection of the first through hole is located within the projection of the avoidance hole; the nut mounting limit structure is formed by injection molding.

[0014] As can be seen from the above, the above design can ensure that the vertical limiting rib cooperates with the support plate to reliably clamp and fix the nut in the axial direction of the first through hole, so as to avoid the nut from moving in the axial direction of the first through hole after being installed in the clamping position, thereby reducing the risk of the nut detaching from the clamping position, and at the same time enabling the bolt to be connected to the threaded hole on the nut more accurately and quickly.

[0015] In order to achieve the second purpose of the present invention, the present invention provides a lens fixing member, wherein the lens fixing member comprises a main body and the above-mentioned nut installation and limiting structure, and the main body comprises a lens installation position.

[0016] As can be seen from the above, the lens fixing part provided with the above-mentioned nut mounting limit structure, when being installed in the lamp cavity of the lamp body of the lamp fixture, only needs to install the nut into the clamping position of the nut mounting limit structure first, and then drive the nut into the lamp cavity from the tail of the lamp body and connect it with the nut to complete the fixed connection of the lamp body and the lens fixing part; although the operating space in the lamp cavity is small, since there is no need to use a wrench to fix or twist the nut during the assembly process of the lamp body and the lens fixing part, the assembly of the lamp body and the lens fixing part is more convenient and easy to operate, effectively improving the assembly efficiency of the lamp body and the lens fixing part, and maintenance is more convenient; in addition, the lens fixing part is used to first fix the lens on itself and then assemble it with the lamp body, thereby making the installation of the lens more convenient, and can eliminate the traditional accumulated tolerance when clamping and fixing the lens by the light source module installed at the bottom of the lamp cavity and the anti-glare ring installed on the lamp body, ensuring the compactness of the lamp after assembly and preventing the lens from loosening.

[0017] A further solution is that the main body is formed with an avoidance groove from its outer peripheral wall inwardly; the nut installation limit structure is located in the avoidance groove, the support plate is connected to the groove wall of the avoidance groove, and the axial direction of the first through hole, the extension direction of the avoidance groove, and the height direction of the main body are roughly parallel to each other.

[0018] As can be seen from the above, this design can reduce the space required by the lens fixing member, which is beneficial to the miniaturization design of the lamp equipped with the lens fixing member and is beneficial to reducing the production cost of the lamp.

[0019] In order to achieve the third purpose of the utility model, the utility model provides a lamp, including a lamp body, a lens, a nut and a bolt, the lamp body having a lamp cavity, and the bottom of the lamp body is provided with a second through hole running through the lamp body, wherein the lamp also includes the above-mentioned lens fixing part, the lens is installed in the lens mounting position, the lens fixing part is located in the lamp cavity, the nut is installed in the clamping position, and the bolt passes through the second through hole and the first through hole and is threadedly connected to the nut.

[0020] As can be seen from the above, the lamp provided with the above-mentioned lens fixing member is simpler and easier to operate when assembling the lamp body, lens and lens fixing member.

[0021] A further solution is that the lamp also includes a light source module, a substrate of the light source module is provided with a third through hole running through the light source module, the light source module is clamped between the bottom wall of the lamp cavity and the lens fixing member, and the bolt also passes through the third through hole.

[0022] As can be seen from the above, this design can further reduce the difficulty of assembling the lamp, simplify the assembly steps, and reduce production costs.

[0023] A further solution is that a first engaging structure is provided in the lens mounting position, a second engaging structure is provided on the lens, and the first engaging structure is engaged with the second engaging structure.

[0024] As can be seen from the above, this design makes the disassembly and assembly between the lens and the lens fixing member more convenient and easy to operate, thereby helping to further improve the assembly efficiency of the lamp.

[0025] In order to achieve the fourth purpose of the present invention, the present invention provides a lighting system, including a control terminal, wherein the lighting system also includes the above-mentioned lamp; the control terminal is electrically connected to the lamp, and / or the control terminal and the lamp exchange information.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0031] Lamp Example

[0032] This embodiment takes the application of the nut installation limiting structure to the lens fixing part of the lamp as an example to assist in explaining the nut installation limiting structure; however, it should be noted that the nut installation limiting structure can also be applied to other technical fields outside the technical field of lamps to assist bolts and nuts in fixing and connecting two or more parts.

[0033] Reference Figure 1 The lamp 100 includes a lamp body 1, a lens holder 2, a lens 3, a light source module 4, a nut 5, and a bolt 6. The lamp body 1 has a lamp cavity 10, with a second through hole provided at the bottom of the lamp cavity 10, which extends through the lamp cavity 10 in its depth direction. The lens 3 is mounted on the lens holder 2. The lens holder 2 and the light source module 4 are both located within the lamp cavity 10, and the light source module 4 is clamped between the bottom wall of the lamp cavity 10 and the lens holder 2. The nut 5 is mounted on the lens holder 2, and the bolt 6 passes through the second through hole from outside the lamp cavity 10 and is threadedly connected to the nut 5, thereby fixing the lamp body 1, the lens holder 2, and the light source module 4.

[0034] Combine Figure 2The lens fixing member 2 has a main body 21 and a nut mounting limit structure 22. The main body 21 has a lens mounting position 211, which is used to accommodate and fix the lens 3. This design allows the lens 3 to be first fixed to the lens fixing member 2, and then moved and installed with the lens fixing member 2 into the lamp cavity 10 of the lamp body 1, thereby making the installation of the lens 3 simpler and more convenient, and eliminating the cumulative tolerance that exists when the lens 3 is clamped and fixed by the traditional light source module 4 installed at the bottom of the lamp cavity 10 and the anti-glare ring installed on the lamp body 1, thereby ensuring the compactness of the lamp 100 after assembly and preventing the lens 3 from loosening.

[0035] Preferably, a first snap-fit ​​structure 2111 is provided in the lens mounting position 211, and the lens 3 is provided with a second snap-fit ​​structure 31 that cooperates with the first snap-fit ​​structure 2111, so that when the lens 3 and the lens fixing component 2 are assembled, it is only necessary to install the lens 3 into the lens mounting position 211 and make the first snap-fit ​​structure 2111 and the second snap-fit ​​structure 31 snap-fit ​​connected to complete the assembly of the lens 3 and the lens fixing component 2, making the disassembly and assembly between the lens 3 and the lens fixing component 2 simpler, more convenient and easier to operate.

[0036] Furthermore, the main body 21 is formed with an avoidance groove 212 inwardly from its outer peripheral wall. The avoidance groove 212 preferably passes through the lens fixing part 2 in the height direction of the lens fixing part 2 (i.e., the depth direction of the lamp cavity 10). The nut mounting limit structure 22 is arranged in the avoidance groove 212. This design can reduce the space required to be occupied by the lens fixing part 2 (such as the space of the lamp cavity 10), thereby being conducive to the miniaturized design of the lamp 100 and reducing the production cost of the lamp 100.

[0037] Combine Figure 3 and Figure 4 The nut mounting limiting structure 22 includes a support plate 221, a transverse limiting rib 222, a vertical limiting rib 223, and a bent limiting rib 224. In this embodiment, the support plate 221 is connected to the groove wall of the avoidance groove 212. The support plate 221 is provided with a first through hole 2211, which passes through the support plate 221. The axial direction of the first through hole 2211 is substantially parallel to the extension direction of the avoidance groove 212.

[0038] The transverse limiting rib 222 is connected to the support plate 221 and is preferably located on the side of the support plate 221 facing away from the bottom of the lamp cavity 10. There are two transverse limiting ribs 222, and the first through hole 2211 is located between the two transverse limiting ribs 222.

[0039] The vertical limiting rib 223 is connected between the two transverse limiting ribs 222. A clamping position 220 is formed between the vertical limiting rib 223, the support plate 221, and the two transverse limiting ribs 222. The clamping position 220 has an insertion opening 2201. In this embodiment, the transverse limiting rib 222 extends along the insertion direction X of the clamping position 220 and extends generally along the recessed direction of the avoidance groove 212. The insertion direction X is generally perpendicular to the axial direction of the first through hole 2211. Furthermore, the number of vertical limiting ribs 223 is preferably two, and the two vertical limiting ribs 223 are distributed along the insertion direction X. In the insertion direction X, the first through hole 2211 is located between the two vertical limiting ribs 223. This design can ensure that the vertical limiting rib 223 cooperates with the support plate 221 to reliably clamp and fix the nut 5 in the axial direction of the first through hole 2211, so as to avoid the nut 5 from moving in the axial direction of the first through hole 2211 after being installed in the clamping position 220, thereby reducing the risk of the nut 5 detaching from the clamping position 220, and at the same time enabling the bolt 6 to be connected to the threaded hole on the nut 5 more accurately and quickly.

[0040] It should be noted that, as another optional scheme, in other embodiments, in the insertion direction X, the vertical limiting rib 223 can extend from the downstream end of the transverse limiting rib 222 to the insertion port 2201, and at the same time, an avoidance hole is provided on the vertical limiting rib 223, and the avoidance hole passes through the vertical limiting rib 223 in the axial direction of the first through hole 2211. At the same time, it is ensured that in the axial direction of the first through hole 2211, the projection of the first through hole 2211 coincides with the projection of the avoidance hole, or the projection of the first through hole 2211 is located within the projection of the avoidance hole.

[0041] The bending limit rib 224 is connected between the two transverse limit ribs 222. Along the insertion direction X, the bending limit rib 224 protrudes outward toward the clamping position 220 in a bent shape, and the bending limit rib 224 is located at the downstream end of the insertion port 2201. The angle a at the bending limit rib 224 is preferably between 115° and 125°. Preferably, the angle a at the bending limit rib 224 is 120°, which is consistent with the angle of the corner of the nut 5. When the nut 5 is installed in the clamping position 220, one corner of the nut 5 can be aligned with the bending limit rib 224. The bending limit rib 224 is used to limit the nut 5 in the insertion direction X so that the threaded hole of the nut 5 inserted into the clamping position 220 is aligned with the first through hole 2211, ensuring that the bolt 6 can smoothly pass through the threaded hole of the nut 5 after passing through the first through hole 2211 of the support plate 221, thereby improving assembly efficiency.

[0042] Preferably, two or more tightening bars 2221 are formed on the side of the transverse limiting rib 222 facing the other transverse limiting rib 222, with a gap between adjacent tightening bars 2221. In this embodiment, the tightening bars 2221 extend generally along the axial direction of the first through hole 2211, and the two or more tightening bars 2221 are distributed from the bent limiting rib 224 toward the insertion opening 2201 in the insertion direction X. Preferably, along the insertion direction X, the tightening bars 2221 can be provided only in the middle and downstream portions of the transverse limiting rib 222, thereby simplifying the structure of the transverse limiting rib 222 and reducing molding difficulty and production costs. Under the premise of ensuring that the tightening reinforcement 2221 and the tightening reinforcement 2221 of another transverse limiting rib 222 reliably clamp and fix the nut 5, this design effectively avoids the need for the entire side wall of the nut 5 to contact the entire wall of the transverse limiting rib 222 by providing the tightening reinforcement 2221, thereby reducing the friction force experienced by the nut 5 when assembled into the clamping position 220, thereby facilitating the assembly of the nut 5 into the clamping position 220. It should be noted that, as another optional solution, in other embodiments, the tightening reinforcement 2221 can also be designed to extend along the insertion direction X to the bending limiting rib 224, and more than two tightening reinforcements 2221 can be distributed along the axial direction of the first through hole 2211.

[0043] By designing the nut installation limiting structure 22, the nut 5 can be installed in the clamping position 220 of the nut installation limiting structure 22 and be fixed in position, thereby preventing the nut 5 and the bolt 6 from rotating during the assembly process. At the same time, due to the function of the nut installation limiting structure 22, there is no need to use a wrench to fix or twist the nut 5 during the assembly process, so the space restriction is small and the assembly efficiency can be improved.

[0044] The base plate of the light source module 4 is provided with a third through hole 41, which mates with the first through hole 2211 and the second through hole. When the lamp body 1, lens holder 2, and light source module 4 are assembled, a bolt 6 passes from the outside of the lamp body 1 through the first through hole 2211, the third through hole 41, and the second through hole, and then threadedly engages with a nut 5 secured within the clamping position 220 of the nut mounting and retaining structure 22. Consequently, when the lamp body 1 and lens holder 2 are secured, the light source module 4 is also clamped and secured between the lamp body 1 and the lens holder 2. The light source module 4 is also retained by the third through hole 41 and the bolt 6, preventing radial movement of the light source module 4 in the direction of the third through hole 41. This design eliminates the need for separate fastening components (e.g., bolts and nuts) or fasteners (e.g., bolts) to assemble the light source module 4 and the lamp body 1. This further reduces the assembly difficulty of the lamp 100, simplifies the assembly steps, and reduces production costs.

[0045] In summary, it can be seen that the lens fixing part 2 of the lamp 100 is provided with the above-mentioned nut installation limiting structure 22, so that when the lens fixing part 2 and the light source module 4 are installed in the lamp cavity 10 of the lamp body 1 of the lamp 100, it is only necessary to first install the nut 5 into the clamping position 220 of the nut installation limiting structure 22, and then drive the nut 5 into the lamp cavity 10 from the tail of the lamp body 1 and connect it with the nut 5 to complete the fixed connection of the lamp body 1, the lens fixing part 2 and the light source module 4; although the operating space in the lamp cavity 10 is small, since the lamp body 1, the lens fixing part 2, and the light source module 4 do not need to be fixed or twisted with the help of a wrench during the assembly process, the assembly of the lamp body 1, the lens fixing part 2 and the light source module 4 is more convenient and easy to operate, which effectively improves the assembly efficiency of the lamp 100 and is more convenient to maintain.

The lamp also includes a control unit, and the control unit is electrically connected to the light source module; the control terminal is electrically connected to the control unit of the lamp, and / or the control terminal and the control unit exchange information. The control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the control unit. When the control terminal is an intelligent control panel or a remote control, a first wireless communication module is provided on the control unit and a second wireless communication module is provided on the control terminal; the control terminal is electrically connected to the control unit, and / or the first wireless communication module and the second wireless communication module exchange information. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearable device, etc.), and can also be an artificial intelligence robot.
