[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In the technical solution of the utility model, when the connection structure is applied to a lighting fixture, the first component is a lamp pole, and the second component is a lamp cap. During installation, the open end of the sleeve is sleeved on the lamp pole, and the end of the sleeve away from the open end is inserted into the lamp cap, and the plug is driven to move by the transmission rod so that the plug is inserted into the lamp cap, thereby realizing the installation of the lamp cap and the lamp pole; during disassembly, the plug is driven to move by the transmission rod so that the plug is separated from the lamp cap, so that the lamp cap can be disassembled, and tool-free disassembly of the lamp cap can be realized. It can be understood that the technical solution can realize the replacement of the lamp cap without the use of tools, thereby improving work efficiency, and at the same time, it also avoids the risk of tools falling due to carrying tools when replacing the lamp cap in the air.

[0031] The main purpose of the utility model is to provide a connection structure 100 to solve the problem that the connection between the lamp holder and the lamp pole requires the use of tools, resulting in low work efficiency.

[0032] See also Figures 1 to 7 As shown, in one embodiment of the utility model, a connecting structure 100 is used to connect a first element 200 and a second element 300, including a sleeve 110, an open end 111 of the sleeve 110 is used to sleeve the first element 200, and the end of the sleeve 110 facing away from the open end 111 can extend into the second element 300; and a plug-in component 120, including a transmission rod 121 and a plug 122, the transmission rod 121 is transmission-connected to the plug 122, the transmission rod 121 can be movably connected to the outside of the sleeve 110, and the plug 122 moves with the transmission rod 121, and is used to be inserted into or detached from the second element 300.

[0033] In this embodiment, the connection structure 100 is arranged between the first element 200 and the second element 300. When the first element 200 and the second element 300 are installed and connected, the first element 200 is inserted into the sleeve 110 along the open end 111 of the sleeve 110, so that the sleeve 110 and the first element 200 are sleeved together, and the position of the sleeve 110 is adjusted, that is, the sleeve depth of the sleeve 110 on the first element 200 is adjusted or the angle of the sleeve 110 is rotated, so that the connection structure 100 is installed to the required position, and the connection between the connection structure 100 and the first element 200 is completed; the outer side of the sleeve 110 is movably connected with a plug 120, and the plug 120 includes a transmission rod 121 and a plug 122. The transmission rod 121 is in transmission connection with the plug 122, and the transmission rod 121 drives the plug 122 to move, so that the end of the sleeve 110 away from the connector 120 is extended into the second element 300 for preliminary connection, and the plug 122 is inserted into the second element 300 through the movable transmission rod 121, and then the second element 300 and the connecting structure 100 are locked together to realize the connection between the first element 200 and the second element 300; when the second element 300 needs to be disassembled, the plug 122 is separated from the second element 300 through the movable transmission rod 121 to release the assembly of the second element 300 and the connecting structure 100. At this time, the second element 300 can be disassembled to realize the tool-free disassembly of the second element 300. It can be understood that the sleeve 110 can be a hollow cylinder with a through-hole arrangement inside, or a cylinder with a certain depth inside but not through-hole arrangement. The shape of the internal channel of the sleeve 110 can be a circular channel, a rectangular channel or a channel matching the shape of the first element 200, so that the first element 200 can be movably mounted on the sleeve 110. Such a channel arrangement can, on the one hand, play a guiding role when the first element 200 is mounted, and on the other hand, can adjust the installation position to a certain extent.

[0034] Further, in the present embodiment, the plug 122 is a convex block, and the shape of the convex block can be a rectangular convex block, a cylindrical convex block, a conical convex block, or other special quadrilateral convex blocks such as a trapezoidal convex block, etc. The present embodiment is preferably a rectangular convex block. It can be understood that a socket, a slot, a hole or other plug interface structure with a certain depth for the plug 122 to be inserted is correspondingly provided on the second element 300, so that the plug 122 can be stably inserted therein without using tools, so that the second element 300 cannot be separated from the connection structure 100. Of course, in other embodiments, the plug 122 can also be in other forms, such as a buckle, a magnetic buckle, a latch, etc. Correspondingly, the second element 300 should also be provided with a plug interface structure matching the plug 122, which is determined according to actual conditions and is not limited here. The movement of the connector 120 on the sleeve 110 can be completed by hand without the use of tools. The movement direction or method can be: moving along the length direction of the sleeve 110, moving along the radial direction of the length direction of the sleeve 110, moving in a circular motion with any point on the sleeve 110 as the center, etc. The movement of the connector 120 can make the plug 122 inserted into or detached from the second component 300, thereby realizing tool-free disassembly and assembly of the second component 300. The embodiments of the utility model are not limited to this, and the above are all within the protection scope of the utility model.

[0035] See also Figures 1 to 3 As shown, further, the connector 120 also includes a connecting rod 123, the transmission rod 121 and the plug 122 are respectively connected to the two ends of the connecting rod 123, the transmission rod 121 and the plug 122 are arranged opposite to each other, the transmission rod 121 drives the plug 122 to move through the connecting rod 123, and the plug 122 is inserted into or detached from the second element 300 along the movement direction of the transmission rod 121.

[0036] In this embodiment, the plug connector 120 includes a plug 122, a connecting rod 123 and a transmission rod 121. The connecting rod 123 is arranged between the transmission rod 121 and the plug 122. The transmission rod 121 and the plug 122 are connected through the connecting rod 123. One end of the connecting rod 123 is connected to the plug 122, and the other end is connected to the transmission rod 121. The plug 122 and the transmission rod 121 are arranged opposite to each other and arranged on the same side of the connecting rod 123. The plug connector 120 is hook-shaped as a whole. In this way, when the sleeve 110 is extended into the second element 300, the plug 122 on the movable plug connector 120 is hooked into the slot on the second element 300 to complete the locking, so that the second element 300 is more stably connected to the connection structure 100. The hook-shaped design structure is simple and easy to use, and is more convenient when disassembling and assembling. It is understandable that the hook-shaped connector 120 can move along the axial direction of the sleeve 110 to hook the second element 300, or can move along the radial direction of the sleeve 110 to hook the second element 300. Further, the connector 120 is an integrally formed workpiece, and the plug 122, the connecting rod 123 and the transmission rod 121 are all rectangular, so that the overall structure of the connector 120 is more stable and the production cost can be reduced. It should be noted that in other embodiments, the connection between the plug 122 and the transmission rod 121 can also adopt other forms, such as screw connection, lock connection, lock pin connection, shaft connection, etc., which can be determined according to actual conditions and are not limited here.

[0037] See also Figures 1 to 3 As shown, further, a mounting groove 112 is formed on the outer side of the sleeve 110, and along the extension direction of the mounting groove 112, the end of the transmission rod 121 away from the connecting rod 123 can be movably inserted in the mounting groove 112, and the plug 122 is inserted into or detached from the second element 300 along the extension direction of the mounting groove 112 along the transmission rod 121.

[0038] In this embodiment, the outer side of the sleeve 110 is provided with a mounting groove 112. Specifically, the mounting groove 112 is in the shape of a rectangular column, and a rectangular through groove matching the shape of the transmission rod 121 is opened thereon. The transmission rod 121 moves in the mounting groove 112. The mounting groove 112 plays a guiding and positioning role for the transmission rod 121, preventing the transmission rod 121 from deflecting or shaking during movement, so that the plug 122 can be more accurately and stably inserted into the second element 300. It can be understood that the shape of the convex mounting groove 112 can also be cylindrical or other structures with a certain thickness; in other embodiments, the mounting groove 112 can also be in the form of a concave setting, and is set on the sleeve 110 cylinder body; the form of the groove depends on the transmission rod 121, for example, the cross section of the groove can be rectangular, circular, V-shaped, T-shaped, etc., specifically depending on the shape of the transmission rod 121, so as to achieve the effect of guiding and limiting, all of which are within the protection scope of the present utility model.

[0039] See also Figures 1 to 3 As shown, further, the mounting groove 112 is extended along the radial direction of the sleeve 110 , and the plug 122 is inserted into or separated from the second element 300 along the radial direction of the sleeve 110 along the transmission rod 121 .

[0040] In this embodiment, the installation groove 112 extends in the radial direction of the length direction of the sleeve 110, and the transmission rod 121 slides in the installation groove 112. In this way, the sleeve 110 extends into the second element 300, which can be understood as the two being in the horizontal direction. At this time, there is a radial constraint force between the two, and the installation groove 112 extends in the radial direction so that the plug-in component 120 locks the second element 300 in the radial direction, generating a horizontal constraint force, which is equivalent to constraining and fixing the second element 300 in two directions, making the connection between the second element 300 and the connection structure 100 more stable. Specifically, the extension direction of the installation groove 112 is perpendicular to the length direction of the sleeve 110, and cooperates with the hook structure of the plug-in component 120 to achieve a better locking and limiting effect.

[0041] See also Figure 3 to Figure 4 As shown, further, the transmission rod 121 can movably pass through the installation groove 112, and the end of the transmission rod 121 away from the connecting rod 123 is connected to the anti-slip member 130, and the anti-slip member 130 protrudes out of the plane where the bottom of the installation groove 112 is located.

[0042] In this embodiment, the transmission rod 121 is inserted into the installation groove 112, and one end of the transmission rod 121 away from the connecting rod 123 can extend out of the plane where the bottom wall of the installation groove 112 is located and is connected with an anti-slip member 130, and the maximum outer diameter of the anti-slip member 130 is greater than the groove width of the installation groove 112, so that when the transmission rod 121 slides in the installation groove 112 toward the connecting rod 123 to a set maximum limit, the anti-slip member 130 abuts against the bottom wall of the installation groove 112 to prevent the transmission rod 121 from being separated from the installation groove 112. Specifically, the anti-slip member 130 is a screw with a media, which is connected to the transmission rod 121 by a thread, and the screw with a media has a media portion on the threaded portion, and the diameter of the media portion is greater than the groove width of the installation groove 112. When the transmission rod 121 slides in the installation groove 112 toward the connecting rod 123 to a set maximum limit, the media portion can abut against the bottom wall of the installation groove 112, so that the transmission rod 121 cannot be separated from the installation groove 112. It should be noted that, in other embodiments, the anti-slip component 130 can also take other forms, such as screws or bolts with gaskets, thumb screws, processed parts with a certain shape, and other components with a maximum diameter greater than the width of the installation groove 112, which can prevent the transmission rod 121 from detaching from the installation groove 112. The specific form can be determined according to actual conditions and is not limited here.

[0043] See also Figures 4 to 5As shown, further, a limiting member 140 is protruded from the side wall of the installation groove 112, and a limiting hole 121a is provided on the transmission rod 121. The limiting member 140 can be movably arranged in the limiting hole 121a so that the limiting member 140 can be inserted into or separated from the limiting hole 121a.

[0044] In this embodiment, the transmission rod 121 is provided with a limiting hole 121a, and a limiting member mounting hole 112a is opened on one side wall of the mounting groove 112. The limiting member 140 can be detachably arranged in the limiting member mounting hole 112a. One end of the limiting member 140 protrudes out of the side wall of the mounting groove 112. The limiting member mounting hole 112a and the limiting hole 121a are arranged opposite to each other. When the transmission rod 121 slides in the mounting groove 112 until the limiting hole 121a is aligned with the limiting member mounting hole 112a, one end of the limiting member 140 facing the limiting hole 121a can be stuck into the limiting hole 121a, thereby limiting the transmission rod 121 and further preventing the transmission rod 121 from detaching from the mounting seat.

[0045] Specifically, the limit member 140 is a glass bead screw, and the limit member mounting hole 112a is a threaded through hole. The glass bead screw is threadedly connected to the limit member 140, and a spring is arranged inside the glass bead screw. The end of the glass bead screw close to the limiting hole 121a is a glass bead ball that can be extended and retracted by the internal spring. The limiting hole 121a is a blind hole, and the shape of the hole matches the glass bead screw, specifically a spherical pit hole; the number of the limit member mounting holes 112a is two, and the number of the limiting hole 121a is one. When the transmission rod 121 slides to the position where the plug 122 is completely separated from the second component 300 or the plug 122 is completely inserted into the second component 300, the two limit member mounting holes 112a are respectively opposite to the limiting hole 121a, and when the connector 120 is respectively in these two positions, it can be limited and fixed by the limit member 140. When the transmission rod 121 slides in the installation groove 112, the rod body can slide along the spherical surface of the glass bead screw to squeeze the glass bead at one end. When the limiting hole 121a on the rod body of the transmission rod 121 is aligned with the limiting member installation hole 112a, the glass bead is inserted into the limiting hole 121a due to the elasticity of the spring, completing the limiting of the transmission rod 121; when the limiting needs to be released, due to the spherical design, the transmission rod 121 only needs to be pushed hard, and the rod body will re-squeeze the spherical surface to retract the glass bead, and the limiting of the rod body by the glass bead screw can be released at this time. Such a setting allows the staff to intuitively judge whether the plug-in 120 is in place according to the state of the glass bead inserted into the limiting hole 121a, that is, the plug 122 is completely inserted into or separated from the second component 300; during use, the position of the glass bead screw in the limiting member installation hole 112a can also be adjusted by rotating the screw, thereby adjusting the limiting force of the glass bead screw on the transmission rod 121. Relatively speaking, the closer the glass bead is to the transmission rod 121, the greater the limiting force.

[0046] It should be noted that the position-limiting member 140 can adopt other forms that can automatically limit the transmission rod 121 through elastic action as mentioned above, such as a ball screw, a spring pin, an elastic member with a guide surface such as an inclined surface or a spherical surface at one end, etc.; it can also be a form that requires manual adjustment to limit, such as a bolt, a butterfly screw, etc. When this method is adopted, when the transmission rod 121 slides to the required position, the transmission rod 121 can be limited by manually tightening the bolt, etc. so that one end of the bolt presses the transmission rod 121. Further, the number of the position-limiting member mounting hole 112a and the position-limiting hole 121a can be at least one other number, the position-limiting member mounting hole 112a can be a non-threaded through hole, a threaded hole, a slotted hole, etc., and the position-limiting hole 121a can be a through hole, a blind hole, a slotted hole, etc., depending on the form of the selected position-limiting member 140, which is not limited here.

[0047] See also Figure 3 to Figure 4 As shown, further, a first magnet 150 is provided on the surface of the connecting rod 123 facing the mounting groove 112, and a second magnet 160 is provided on the surface where the notch of the mounting groove 112 is located. The first magnet 150 and the second magnet 160 are arranged opposite to each other, and the first magnet 150 and the second magnet 160 are magnetically attracted to each other.

[0048] In this embodiment, a groove is provided on the surface of the connecting rod 123 facing the installation groove 112 and on the surface where the notch of the installation groove 112 is located, and the first magnet 150 and the second magnet 160 are respectively arranged in the groove. When the plug 122 is fully inserted into the second element 300, the connecting rod 123 and the installation groove 112 abut against each other. At this time, the magnetic surfaces of the first magnet 150 and the second magnet 160 are mutually attracted, so that the plug 120 is attracted to the installation groove 112, preventing the plug 120 from being separated from the installation groove 112, and preventing the plug 122 from being displaced, so that the second element 300 is better connected to the connection structure 100. Specifically, the first magnet 150 and the second magnet 160 are fixed in the groove by screws. The first magnet 150 and the second magnet 160 are permanent magnets. The use of permanent magnets can maintain magnetism for a long time and have a long service life, avoiding frequent replacement of magnets. It should be noted that the first magnet 150 and the second magnet 160 may be installed on the connecting rod 123 and the mounting groove 112 by other means, such as bonding, snap-fitting, welding, etc., which are not limited here.

[0049] See also Figures 1 to 3 As shown, further, a level 170 is disposed on the outer side of the sleeve 110 , and the level 170 is spaced apart from the connector 120 .

[0050] In this embodiment, a groove is provided on one side of the sleeve 110, and a level 170 is installed in the groove. The level 170 is used to assist in reference adjustment of the positions of the first element 200 and the second element 300, and to determine whether the position of the second element 300 connected to the first element 200 through the connection structure 100 meets the horizontal position requirement. If not, it can be adjusted by rotating the sleeve 110. The level 170 is a bubble level 170, which determines the horizontality of the lamp head by observing the position of the bubble in the liquid tube. The bubble level 170 is simple and easy to use, durable and inexpensive, and can intuitively determine the horizontality. Of course, in other embodiments, a digital level 170, a magnetic level 170, etc. can also be used, depending on the actual situation, and is not limited here.

With such an arrangement, when the sleeve 110 is extended into the lamp holder, the channel 310 acts as a guide, and the matching shapes of the two can prevent the sleeve 110 from shifting in the channel 310, and there is no need to adjust the axial position.

[0053] When installing the lamp pole and the lamp holder, first insert the lamp pole into the open end 111, use the level 170 to assist in reference and adjust the position, and after the connecting structure 100 is installed to the required position, tighten the two fixing bolts on the sleeve 110 to press the lamp pole so that the lamp pole is fixed on the connecting structure 100; then extend the end of the sleeve 110 away from the open end 111 where the lamp pole is inserted into the lamp holder along the channel 310 until it is pushed to the innermost part, at this time, slide the connector 120 set on the outside of the sleeve 110, and then insert the plug 122 on the lamp holder to complete the locking of the lamp holder and realize the connection between the lamp holder and the lamp pole; when the lamp holder needs to be replaced, slide the connector 120 to disengage the plug 122 from the lamp holder, and release the locking of the lamp holder by the connecting structure 100. At this time, the lamp holder can be disassembled by pulling it out along the direction of the channel 310 without using tools. The connection between the newly replaced lamp holder and the lamp pole can be repeated with the above installation steps.

[0054] It should be noted that, in some other embodiments, the first element 200 is not limited to the lamp pole, and the second element 300 is not limited to the lamp head. When the first element 200 and the second element 300 are other components, the above-mentioned connection structure 100 is also applicable. For example, in one embodiment, a mop or broom that can be disassembled without tools, the connection between the mop head or broom head and the rod body can be connected through the above-mentioned connection structure 100 to achieve tool-free disassembly of the mop head or broom head. In another embodiment, a selfie stick that can be disassembled without tools, the connection between the bracket for fixing a mobile phone or camera and the rod body can also be connected through the above-mentioned connection structure 100 to achieve tool-free disassembly of the bracket. The embodiments of the utility model are not limited to this, and the above are all within the protection scope of the utility model.

[0055] See also Figure 6 to Figure 7 As shown, further, the plug 122 is formed with a first guide surface 122a, and the first guide surface 122a is arranged away from the transmission rod 121. A socket 311 is formed on the outer side of the lamp holder along the radial direction of the channel 310. A second guide surface 311a is formed on the surface where the socket 311 is located, and the second guide surface 311a is arranged toward the open end of the channel 310. The first guide surface 122a cooperates with the second guide surface 311a so that the plug 122 is inserted into the socket 311.

[0056] In this embodiment, the two sides of the channel 310 are oppositely formed with sockets 311, and correspondingly, the connection structure 100 is also oppositely formed with two installation grooves 112, and the two installation grooves 112 are respectively slidably connected with the plug 120. A first guide surface 122a is formed at one end of the plug 122, and specifically, the first guide surface 122a is a chamfered inclined surface. With such a configuration, on the one hand, when the plug 122 moves to the socket 311 for insertion, the plug 122 can enter the socket 311 more easily through the first guide surface 122a, and will not be stuck and cannot be inserted due to misalignment, making the insertion action smoother; on the other hand, the provision of the guide surface can remove the sharp corners and burrs at the end of the plug 122, and prevent the plug 122 from scratching the socket 311 and affecting the appearance of the lamp holder. It can be understood that one or more guide surfaces can be provided at the end of the plug 122, and the first guide surface 122a can also be a curved surface, which is not limited here.

[0057] Furthermore, a second guide surface 311a is provided on the surface of the socket 311 formed on the outer wall of the channel 310. The second guide surface 311a is an inclined surface. The second guide surface 311a is arranged toward the open end of the channel 310. Since the first guide surface 122a on the plug 122 is arranged on the plug 122 with its back facing the transmission rod 121, when the sleeve 110 is extended into the lamp holder along the channel 310, the first guide surface 122a and the second guide surface 311a face each other. The plug 122 can be displaced along the second guide surface 311a through the cooperation between the first guide surface 122a and the second guide surface 311a. When the sleeve 110 moves into the lamp holder, the second guide surface 311a causes the connector 120 to move upward until the plug 122 slides into the socket 311. With such arrangement, when the sleeve 110 is pushed into the lamp holder, the plug 122 can automatically slide into the socket 311 along the inclined surface, and there is no need to manually slide the connector 120 to insert the plug 122 into the socket 311, making it faster to install the lamp holder.
