Description

Technical Field

[0001] The invention relates to the field of lighting devices, and in particular to a lamp connection structure and an industrial and mining lamp. Background Art

[0002] Industrial and mining lamps are a type of special lamps. They are usually used in factories, warehouses, docks and other places that require high-brightness lighting. They have the characteristics of high strength, waterproof, dustproof and corrosion-resistant.

[0003] In order to meet the installation needs of factories, warehouses, docks and other places, mining lamps sometimes need to be installed on the ceiling to meet the lighting needs of different scenes. However, the connection structure of existing mining lamps for ceiling installation is too simple and cannot meet the ceiling installation needs of different places, resulting in a narrower application range of mining lamps. At the same time, in order to pursue the strength of mining lamps, people add mesh covers at the light output position of mining lamps to resist the impact of foreign objects on the components at the light output position of mining lamps, thereby avoiding damage to the components at the light output position of mining lamps. However, mining lamps are installed at a high place in the use site in the form of ceiling installation and the space above the installation position is not enough to accommodate When the maintenance personnel are invited to perform maintenance operations on the industrial and mining lamp, the maintenance personnel need to perform maintenance operations on the bottom of the industrial and mining lamp, and the mesh cover is undoubtedly the first object to be disassembled for the maintenance operation of the lamp; the connection structure for connecting the mesh cover on the existing industrial and mining lamps is mostly connected by screws. When disassembling, it is necessary to use tools to remove all the screws connecting the mesh cover before the mesh cover can be disassembled. The mesh cover disassembly process takes a long time, and the disassembled mesh cover needs to be held by the maintenance personnel or placed in a tool bag on the body before subsequent maintenance operations can be performed, and the parts removed from the lamp behind the mesh cover will also have a certain impact on the maintenance operations of the maintenance personnel.

[0004] The inability of mining lamps to adapt to the ceiling installation requirements of different venues, as well as the impact of the removal of the mesh cover and other components on the maintenance operation during the maintenance of the lamps, are all related to the connection structure of the components of the mining lamps themselves; therefore, it is necessary to improve the connection structure of the components on the mining lamps.

DETAILED DESCRIPTION

[0037] The present invention discloses a lamp connection structure, such as Figure 1 As shown, the connection structure is arranged in a lamp with a mesh cover 1 and distributed in the lamp housing 2 of the lamp and the top cover 31 of the power box 3. The connection structure includes: The mounting parts 4 are arranged on the edge of the top surface of the lamp housing 2 and the edge of the top cover 31, and are distributed in a matrix manner on the edge of the top surface of the lamp housing 2 and the edge of the top surface of the power box 3; A connecting component 5 is connected to the edge of the mesh cover 1 and is connected to the mounting portion 4. When the two ends of the connecting component 5 are connected to the mesh cover 1 and the lamp housing 2 respectively, the mesh cover 1 is fixed below the lamp housing 2. A hanging member 6 connected to the mounting portion 4 at the edge of the top surface of the lamp housing 2 or the mounting portion 4 at the edge of the top cover 31; Among them, the connecting components 5 are distributed on both sides of the lamp housing 2 in the transverse direction. After the connecting components 5 located on any one side of the lamp housing 2 in the transverse direction are disconnected from the mesh cover 1 or disconnected from the lamp housing 2, the connection between the connecting components 5 on the other side of the lamp housing 2 in the transverse direction and the mesh cover 1 forms the rotation center of the mesh cover 1, thereby realizing the rotation of the mesh cover 1 outside the lamp housing 2.

[0038] It should be noted that after the mesh cover 1 is connected to the lamp housing 2 through the connecting component 5 to achieve a fixed position, it can resist the impact of foreign objects on the lamp at the outer position of the lamp housing 2, thereby playing a role in protecting the lamp. The connection between the connecting component 5 and the mesh cover 1 is simple to operate, and the mesh cover 1 can be quickly assembled and disassembled. When maintaining the lamp from the bottom direction, the mesh cover 1 can be disconnected from the connecting component 5 on either side, or the connection between the connecting component 5 on either side and the lamp housing 2 can be disconnected. The mesh cover 1 can be turned outward under the lamp with the connecting component 5 on the other side that has not been disconnected as the rotation center, so that the mesh cover 1 located under the lamp can be removed when the lamp is maintained, and then Maintenance personnel can start to disassemble the parts of the lamp from the bottom of the lamp to realize maintenance work from the bottom of the lamp; moreover, the mesh cover 1 turned outward from the bottom of the lamp can be used as a tool for loading lamp parts, and the parts removed from the bottom of the lamp can be temporarily placed in the mesh cover 1 for support. Maintenance personnel do not need to manually support the parts removed in advance, making the maintenance operation of the mining lamp simpler and saving the time of mining lamp maintenance; in addition, the connection structure provides a variety of hanging parts structures, so that the mining lamp can choose the ceiling installation method according to different site installation conditions, so that the mining lamp can meet the installation and use requirements of different scenes.

[0039] It needs to be further explained that if Figure 2~Figure 9 As shown in the combination, the connecting component 5 includes a connecting column 51, a protrusion 52 and a hook 53. The mounting portion 4 connected to the connecting component 5 is a first screw hole 41. A plurality of the first screw holes 41 are respectively distributed in a straight line along the edges on both sides of the top surface of the lamp housing 2 in the transverse direction. An external thread 511 is provided at the bottom end of the connecting column 51. The connecting column 51 is matched with the first screw hole 41 through the external thread 511 and its top extends upward to the outside of the first screw hole 41. The protrusion 52 is connected to the top end of the connecting column 51 by an eccentric connection. The hook end 531 of the hook 53 opens toward the connecting column 51. The non-hooking end 532 of the hook 53 is provided with a first matching hole 533, and the connecting column 51 is located in the first matching hole 533. The bottom surface of the end of the protrusion 52 away from the connecting column 51 is provided with a chamfer 521, and the top surface of the non-hooking end 532 outside the first matching hole 533 is provided with a circle of convex edges 534 whose center is coaxial with the connecting column 51. The inner diameter of the convex edge 534 is the same as the distance from the end surface of the protrusion 52 away from the end of the connecting column 51 to the connecting column 51. The top of the connecting column 51 above the protrusion 52 is provided with a matching head 54 with a hexagonal cross-section, and the matching head 54 is matched with a twist handle 55.

[0040] When the mesh cover 1 is installed on the lamp housing 2, the edge of one side of the mesh cover 1 is first hooked on the hook 53 of the connecting component 5 on one side of the lamp housing 2 in the transverse direction, so that one end of the mesh cover 1 is connected to the connecting component 5 on one side of the lamp housing 2 in the transverse direction, thereby first stabilizing the position of one end of the mesh cover 1, and then the edge of the other end of the mesh cover 1 is placed outside the connecting component 5 on the other side of the lamp housing 2 in the transverse direction, that is, at a position outside the hook 53; then the connecting column 51 is rotated by twisting the twist handle 55, and the connecting column 51 will drive the protrusion 52 to rotate together during the rotation process. Since the connecting column 51 and the first screw hole 41 are matched through threads, the height of the protrusion 52 will decrease as the connecting column 51 rotates; as the connecting column 51 continues to rotate, the end of the protrusion 52 that is farther from the connecting column 51 will enter into the first matching hole 533 in a rotational cutting manner, and the wall surface of the end of the protrusion 52 that is farther from the connecting column 51 will abut against the first matching hole 533 away from the hooking end The hook 53 is provided with a plurality of hooks 531 and 532, and the hook 53 is provided with a plurality of hooks 531 and 532, and the hook 53 is provided with a plurality of hooks 532 and 531. The hook 53 is provided with a plurality of hooks 531 and 532, and the ... After the engaging hole 533 is away from the end of the hooking end 531, the connection between the hook 53 and the mesh cover 1 is formed; since the opening direction of the hooking end 531 is toward the connecting column 51, after the hooking end 531 is hooked on the edge of the mesh cover 1, the hooking end 531 will form an inverted hook-type clamping structure, so that a tight connection is formed between the hook 53 and the mesh cover 1, thereby fixing the position of the mesh cover 1 and realizing the installation operation of the mesh cover 1. The whole operation is simple and convenient and can be completed without the use of tools.

[0041] In addition, when the maintenance operation of the lamp is carried out from the bottom of the lamp, the connecting column 51 is rotated in the opposite direction by twisting the handle 55, so that the protrusion 52 is rotated in the opposite direction and screwed out from the first matching hole 533. In this process, the protrusion 52 squeezes the side wall of the end of the first matching hole 533, so that the non-hooking end 532 of the hook 53 rotates accordingly, so that the hooking end 531 of the hook 53 is screwed out from the edge of the mesh cover 1, thereby releasing the connection between the connecting component 5 and the mesh cover 1; in this way, the position of one end of the mesh cover 1 can no longer be fixed, and the connection component 5 on the other side of the lamp housing 2 in the lateral direction can be fixed. The hook 53 is connected to the edge of the mesh cover 1 at a position where the edge of the mesh cover 1 and the hook end 531 of the hook form an axially connected structure. This structure is used as the rotation center of the mesh cover 1, so that the mesh cover 1 can rotate under the lamp housing 2, and the mesh cover 1 can be turned outward from the bottom of the lamp. Moreover, when the mesh cover 1 is damaged, after the mesh cover 1 can achieve the condition of rotation, the edge of the mesh cover 1 located at its rotation center can be removed from the hook 53 on the other side of the lamp housing 2 in the lateral direction, thereby realizing the disassembly of the entire mesh cover 1, which is convenient and quick to operate.

[0042] Specifically, Figure 2~Figure 9 As shown in the combination, the first matching hole 533 is a waist hole and the radii at both ends are the same. The radius of the first matching hole 533 close to the hook end 531 is the same as the radius of the end of the protrusion 52 located on the outside of the chamfer 521. When the end of the protrusion 52 away from the connecting column 51 cuts into the first matching hole 533 from the middle to the end of the first matching hole 533 close to the non-hook end 532 in a spiral cutting manner, the wall of the protrusion 52 on the chamfer 521 side is tangent to one of the side walls of the middle of the first matching hole 533 and the wall of the first matching hole 533 close to the non-hook end 532, and the hook 53 moves toward the center of the lamp housing 2 as the end of the protrusion 52 away from the connecting column 51 continuously enters into the end of the first matching hole 533 close to the non-hook end 532, until the end of the protrusion 52 away from the connecting column 51 completely enters into the end of the first matching hole 533 close to the non-hook end 532 and stops moving.

[0043] Among them, when the end of the protrusion 52 away from the connecting column 51 cuts into the first matching hole 533 from the middle of the first matching hole 533 to the end of the first matching hole 533 close to the non-hooking end 532 in a spiral cutting manner, the non-hooking end 532 of the hook 53 will be pressed down and rotated by the protrusion 52. At this time, the wall surface of the chamfer 521 of the protrusion 52 and the wall surface of the hook 53 in the middle of the first matching hole 533 and the wall surface of the hook 53 at the end of the first matching hole 533 close to the non-hooking end 532 are tangent to each other. The friction between the protrusion 52 and the wall surface of the hook 53 enables the rotation of the protrusion 52 to drive the non-hooking end 532 of the hook 53 to rotate. When the hook end 531 of the hook 53 is pressed against the edge of the mesh cover 1, since the wall surface where the hook end 531 and the edge of the mesh cover 1 are pressed is an arc surface, and the opening wall surface of the hook 53 at this position has a small contact area with the edge surface of the mesh cover 1 during the rotation and cutting process, the force required to overcome the deformation and rotation of the hook end 531 is smaller than the friction force required to overcome when the protrusion 52 rotates further, so that the hook end 531 can be clamped into the edge of the mesh cover 1; and after the hook end 531 is clamped into the edge of the mesh cover 1, the friction force between the protrusion 52 and the wall surface of the hook 53 at the first matching hole 533 still exists, The two still remain in a relatively static state; the protrusion 52 and the non-hooking end 532 of the hook 53 further rotate, and at this time, the swing of the hook end 531 generates a force on the edge of the mesh cover 1 through the wall surface of the opening of the hook 53, and the wall surface of the opening of the hook 53 gradually contacts the surface of the edge of the mesh cover 1, and the contact area between the two is constantly increasing, and the effect of the hook end on the mesh cover 1 is also gradually increasing; when this force exceeds the friction force that needs to be overcome when the protrusion 52 rotates further, the protrusion 52 continues to rotate and the end of the protrusion 52 away from the connecting column 51 is gradually screwed into the first matching hole 533 away from the hook end 531 The hook 53 is inside the end portion, and at this time, the hook 53 is affected by the force of the protrusion 52 away from the end portion of the connecting column 51. The direction of the force will change as the protrusion 52 moves away from the end portion of the connecting column 51 and continuously enters the end portion of the first matching hole 533 close to the non-hooking end 532. The protrusion 52 moves away from the end portion of the connecting column 51 to squeeze the wall surface of the hook 53 outside the end portion of the first matching hole 533 close to the non-hooking end 532, and causes the hook to gradually move toward the center of the lamp housing 2. At the same time, the hook end 531 of the hook 53 tightens the edge of the mesh cover 1, thereby further tightening the connection between the hook 53 and the mesh cover 1, thereby playing the role of fixing the position of the mesh cover 1.

[0044] It needs to be further explained that if Figure 10~Figure 13As shown in combination, the connecting component 5 includes a clip 56 and a first screw 57. The cross-section of the clip 56 is in the shape of a hairpin and one end of which is provided with a clamp 561. The end of the clip 56 away from the clamp 561 is fitted on the edge of the mesh cover 1, and the end of the clip 56 close to the clamp 561 is provided with a second fitting hole 562. The mounting portion 4 on the edge of the top surface of the lamp housing 2 is a second screw hole 42, and the first screw 57 is fitted into the second fitting hole 562 and the second screw hole 42 in sequence.

[0045] Among them, the clip 56 is first clamped on the edge of the mesh cover 1 along the direction in which the clamping opening 561 cooperates with the edge of the mesh cover 1, and then the mesh cover 1 is placed at a position below the lamp housing 2, and the clip 56 is placed on the surface of the lamp housing 2 along the position of the second matching hole 562 corresponding to the second screw hole 42, and then the first screw 57 is inserted into the second matching hole 562, and then the first screw 57 is continued to be screwed into the second screw hole 42 through a tool, thereby connecting the connecting component 5 with the lamp housing 2, and then fixing the mesh cover 1 at a position below the lamp housing 2; when the entire mesh cover 1 needs to be removed from below the lamp housing 2, after removing the first screws 57 in all the connecting components 5, the entire mesh cover 1 can be removed from the lamp.

[0046] In addition, when performing maintenance operations on the lamp from the bottom of the lamp, after removing the first screw 57 in all the connecting components 5 on one side of the lamp housing 2 in the lateral direction by tools, the connecting components 5 on one side of the mesh cover 1 will not fix the position of this end of the mesh cover 1, while the other side of the mesh cover 1 still remains connected to the lamp housing 2. Since the clip 56 is connected to the edge of the mesh cover 1, the edge of the mesh cover 1 and the clamping opening 561 are equivalent to an axially connected structure. Therefore, the other side of the mesh cover 1 uses this axially connected structure as the rotation center of the mesh cover 1, so that the mesh cover 1 can be turned outward from the bottom of the lamp.

[0047] It needs to be further explained that if Figure 1 , Fig.14 and Fig.15As shown in combination, the hanging part 6 is a first connecting frame 61, the mounting part 4 includes a third screw hole 43, and upwardly extending protrusions 311 are provided on both sides of the top cover 31, and the third screw hole 43 is arranged at the protrusion 311, the first connecting frame 61 is arched and the bottom ends of both sides thereof are provided with fourth screw holes 611, and the number of the third screw holes 43 and the fourth screw holes 611 is at least two, and the first connecting frame 61 is connected to the top cover 31 by the second screws 62 connected to the third screw holes 43 and the fourth screw holes 611, and the top of the first connecting frame 61 is respectively provided with a first mounting hole 612 and a second mounting hole 613, the first mounting hole 612 is located in the middle of the first connecting frame 61, and the second mounting hole 613 is located on the top surface of the first connecting frame 61 outside the two sides of the first mounting hole 612.

[0055] It needs to be further explained that if Fig.18 As shown, the hanging component 6 includes a hanging rope 65 and a connecting buckle 66, the mounting portion 4 includes a first through hole 46, and upwardly extending protrusions 311 are provided on both sides of the top cover 31. The first through hole 46 is arranged at the protrusion 311, and connecting rings are provided at both ends of the hanging rope 65. The connecting buckle 66 respectively cooperates with one of the connecting rings in the hanging rope 65 and the first through hole 46, and the connecting buckle 66 at the bottom of the hanging rope 65 cooperates with the first through hole 46.

[0056] When the hanging rope 65 is connected to the top cover 31, the connecting buckle 66 at one end of the hanging rope 65 is opened, and the connecting buckle 66 is passed through the first through hole 46 and then closed, so that the connecting buckle 66 is buckled at the first through hole 46 to realize the connection between the hanging rope 65 and the top cover 31; and a fixing component with a through hole can be installed at the position on the wall where the hanging rope 65 is connected, so that the connecting buckle 66 on the other end of the hanging rope 65 can be buckled on the through hole, thereby realizing its connection with the hanging rope 65, and then realizing the ceiling installation of the lamp.

[0057] The present invention also discloses a mining lamp, such as Figure 1 to Figure 20As shown in the combination, it includes a mesh cover 1, a power supply component 7 arranged in the power supply box 3, a light source component 8 arranged in the lamp housing 2, a light-transmitting plate 9, a positioning frame 10 and the above-mentioned connection structure, the positioning frame 10 is connected to the bottom of the lamp housing 2, and a second through hole 101 is provided in the middle of the positioning frame 10.
