[0002] With the continuous innovation of lamp technology, more and more types of lamps have emerged on the market. In the past, the lamp heads on most lamps were connected in a non-detachable manner with the lamp body.
[0003] Now, there appears a type of lamp different from the lamp head connection structures of most lamps. Based on the existing lamp head connection structures of most lamps, the lamp head connection structure of this type of lamp adds a lamp head connection structure that allows the lamp head to work independently outside the lamp body, that is, a lamp head connection structure detachably connected to the lamp body. For a lamp with this lamp head connection structure, if there are defects in the connection tightness between the lamp head and the lamp body when the lamp head is connected to the lamp body, it is easy to cause the lamp head to separate from the lamp body when the lamp works as an integral structure, resulting in the lamp head being unable to normally irradiate in the required direction, and there is also a risk of damage to the lamp head. Moreover, when the lamp head is connected to the lamp body, if a structure convenient for the alignment of the two is not provided between the lamp head and the lamp body, it will affect the operation convenience of connecting the lamp head to the lamp body, and will also cause the deviation of the lamp head connection position, affecting the overall regularity of the lamp. Summary of the Utility Model
[0004] In view of the technical defects in the background art, the utility model provides a lamp head connection structure and a lamp, which solve the above technical problems and meet the actual requirements. The specific technical solutions are as follows:
[0005] The utility model discloses a lamp head connection structure, including a fitting block arranged on the lamp head and a connecting member arranged on the lamp body. The fitting block is arranged at the end of the lamp head far from the light-emitting side. A recessed part is circumferentially arranged on the side wall of the fitting block, and a clamping groove is arranged in the recessed part. A plurality of connecting members are circumferentially arranged at the end of one axial direction of the lamp body. A protruding part is arranged on one side wall surface of the connecting member. The lamp head is connected to the lamp body through the cooperation of the clamping groove and the protruding part. A convex edge is arranged on the edge of the axial end surface of the lamp body where the connecting member is located. The space surrounded by the convex edge forms a fitting groove with the same contour as the side wall contour of the fitting block.
[0006] As a further embodiment of the utility model, the convex edge is provided with a plurality of first connecting grooves for connecting the connecting members. An opening is arranged on the wall surface of the convex edge near the inner edge of the first connecting groove. The end of the connecting member near the protruding part is fitted in the opening, and the protruding part is placed in the space where the fitting groove is located.
[0007] As a further embodiment of the present utility model, a clamping hole is provided on the wall surface of the convex edge close to the outer edge side of the first connection groove, a convex block with a wedge-shaped cross-section is provided on the side wall surface of the connecting member away from the protruding portion, and the connecting member is detachably connected to the lamp head by clamping the convex block in the clamping hole.
[0008] As a further embodiment of the present utility model, the shapes of the clamping groove and the protruding portion are both frustum-shaped.
[0009] As a further embodiment of the present utility model, it further includes a second connection groove for connecting the steering joint, and the second connection groove is arranged on the side wall of the lamp head.
[0010] As a further embodiment of the present utility model, it further includes a plurality of grooves arranged circumferentially along the side wall of the lamp head.
[0011] The present utility model also discloses a lamp, which includes a lamp head, a lamp body, a steering joint, a telescopic connecting rod and a support leg, and also includes the lamp head connection structure described above. One end of the steering joint is fixedly connected to the second connection groove, one end of the telescopic connecting rod is fixedly connected to the lamp body, the other end of the steering joint is movably connected to the other end of the telescopic connecting rod, and the support leg is pivotally connected to the lamp body and rotates into the groove with the end where it is pivotally connected to the lamp body as the rotation center.
[0012] The beneficial effects of the present utility model are as follows:
[0013] In the lamp head connection structure, after the clamping groove on the surface of the mating block provided at the end of the lamp head is clamped with the protruding portion on the connecting member, the detachable connection between the lamp head and the lamp body can be realized. Through the connection of the two, the lamp can be used as a whole. The lamp head can also be separated from the lamp body and work independently outside the lamp body, so that the lamp equipped with this lamp head connection structure can be applicable to different usage scenarios; moreover, after the lamp head and the lamp body are connected, the mating block will fit into the mating groove and the recessed portion is close to the inner edge position of the convex edge, thereby restricting the rotational movement of the lamp head relative to the lamp body through the abutment of the two, keeping the positions of the lamp head and the lamp body relatively stationary, facilitating the positioning of the lamp head when connecting to the lamp body, making the connection between the lamp head and the lamp body closer, and having higher structural stability when the lamp works as a whole.

Detailed implementation mode
[0024] The present utility model discloses a lamp head connection structure. As Figures 1 - 5 shown in combination, it includes a mating block 11 provided on the lamp head 1 and a connector 21 provided on the lamp body 2. The mating block 11 is provided at the end of the lamp head 1 away from the light-emitting side. The side wall of the mating block 11 is circumferentially provided with a recess 111, and a clamping groove 112 is provided in the recess 111. A plurality of connectors 21 are circumferentially provided at one axial end of the lamp body 2. One side wall surface of the connector 21 is provided with a protruding part 211. The lamp head 1 is connected to the lamp body 2 through the cooperation of the clamping groove 112 and the protruding part 211. An annular convex edge 22 is provided at the edge of the axial end surface of the lamp body 2 where the connector 21 is located. The space surrounded by the convex edge 22 forms a mating groove 221 with the same contour as the side wall contour of the mating block 11.
[0025] It should be noted that when the lamp head 1 needs to be connected to the lamp body 2, the mating block 11 is inserted into the inside of the connecting member 21 along the direction in which the wall surface of the mating block 11 located outside the clamping groove 112 cooperates with the wall surface outside the convex portion 211. During this process, the convex portion 211 on the connecting member 21 will be fitted into the clamping groove 112, so that the lamp head 1 is connected to one end of the lamp body 2 in one axial direction. Through the connection of the two, the lamp can be formed into a whole for use. Since the connection between the convex portion 211 and the clamping groove 112 is a detachable connection, the lamp head 1 can be pushed away from the lamp body 2 to move outside the lamp body 2 until the convex portion 211 disengages from the clamping groove 112, so that the lamp head 1 can be separated from the lamp body 2 and work independently outside the lamp body 2, so that the lamp equipped with this lamp head connection structure can be applied to different usage scenarios.
[0026] Secondly, after the lamp head 1 is connected to the lamp body 2, the mating block 11 will be fitted into the mating groove 221, which is convenient for positioning the lamp head 1 when it is connected to the lamp body 2. Moreover, since the surface contour of the recessed portion 111 is the same as the contour of the inner edge surface of the convex edge 22, and the positions of the two are close, when the lamp head 1 makes a rotating motion relative to the lamp body 2, the recessed portion 111 will abut against the inner edge of the convex edge 22, thereby restricting the rotating motion of the lamp head 1, making the positions of the lamp head 1 and the lamp body 2 relatively stationary, making the connection between the lamp head 1 and the lamp body 2 tighter, and the structural stability higher when the lamp works as a whole.
[0027] In addition, the connecting member 21 of this embodiment can be connected to the edge of the axial end face of the lamp body 2 by a fixed connection method, that is, the connecting member 21 can be separately arranged at the end of the lamp body 2. Since the wall surface of the connecting member 21 where the convex portion 211 is located will be close to the wall surface of the recessed portion 111 where the clamping groove 112 is located after the convex portion 211 and the clamping groove 112 are engaged, and a plurality of connecting members 21 are arranged in the circumferential direction of the lamp body 2 and a plurality of recessed portions 111 are arranged in the circumferential direction of the lamp head 1, so the connecting member 21 forms a plurality of points restricting the rotational movement of the lamp head 1 in the circumferential direction of the lamp head 1, and the same effect of keeping the positions of the lamp head 1 and the lamp body 2 relatively stationary can be achieved.
[0028] As one of the embodiments of the present invention, as Figure 4 shown, the convex edge 22 is provided with a plurality of first connection grooves 222 for connecting the connecting member 21. The wall surface of the convex edge 22 near the inner edge side of the first connection groove 222 is provided with an opening 223. The end of the connecting member 21 near the convex portion 211 is fitted into the opening 223, and the convex portion 211 is placed in the space where the mating groove 221 is located.
[0029] The difference between this embodiment and the previous one is that the connecting member 21 in this embodiment is installed in the connecting groove and integrated with the convex edge 22, rather than directly fixed to the edge of the axial end face of the lamp body 2; in addition, the connection method between the connecting member 21 and the connecting groove can be a fixed connection or a snap connection in the connecting groove to form a connection with the convex edge 22 in a detachable connection manner, thus enriching the connection means of the connecting member 21, and the detachable connection method can replace the connecting member 21 when it is damaged, avoiding affecting the connection between the lamp head 1 and the lamp body 2.
[0030] Specifically, as Figure 4 and Figure 5 As shown in combination, on the wall surface of the convex edge 22 near the outer edge side of the first connecting groove 222, there is a clamping hole 224, and on the side wall surface of the connecting member 21 away from the protruding portion 211, there is a convex block 212 with a wedge-shaped cross-section. The connecting member 21 is detachably connected to the lamp head 1 by clamping the convex block 212 in the clamping hole 224.
[0031] Among them, when the connecting member 21 is connected to the lamp body 2 in a detachable connection manner, the connecting member 21 is inserted along the direction in which the end with the convex block 212 is fitted with the connecting groove. During the insertion process, due to the wedge-shaped cross-section of the convex block 212, the inclined surface on the convex block 212 moves obliquely with the notch of the connecting groove. Since the end of the connecting member 21 with the convex block 212 has a certain elasticity, this part can deform, so that the convex block 212 can enter the connecting groove from the notch of the connecting groove. When the convex block 212 reaches the position where the clamping hole 224 is located, through the elastic recovery of the end of the connecting member 21 with the convex block 212, the convex block 212 is fitted in the clamping hole 224 to realize the detachable connection between the connecting member 21 and the connecting groove; when the connecting member 21 is damaged, an object can be inserted from outside the clamping hole 224 to push the convex block 212 in the clamping hole 224 out of the clamping hole 224, so as to release the connection relationship between the connecting member 21 and the connecting groove, so that the connecting member 21 can be removed from the lamp body 2 for replacement, facilitating the maintenance work of the lamp.
[0032] Specifically, as Figure 6 and Figure 7 As shown in combination, the shapes of the clamping groove 112 and the protruding portion 211 are both frustum-shaped.
[0033] Among them, when the convex portion 211 is located near the notch of the clamping groove 112, the shape of the clamping groove 112 near its notch plays a certain guiding role for the convex portion 211, enabling the convex portion 211 to enter the clamping groove 112 more smoothly; similarly, when the lamp head 1 is detached from the lamp body 2, the convex portion 211 can guide the wall surface of the lamp head 1 in the clamping groove 112, making it easier for the convex portion 211 to move out of the clamping groove 112, thus facilitating the detachment of the lamp head 1 from the lamp body 2.
[0034] Specifically, as Figure 2 and Figure 9 shown in combination, it further includes a second connection groove 12 for connecting the steering joint 3, and the second connection groove 12 is arranged on the side wall of the lamp head 1.
[0035] Among them, the second connection groove 12 is used to connect the steering joint 3 on the lamp. A connection is formed between the lamp head 1 and the steering joint 3. When the lamp is in use, the steering of the lamp head 1 is realized through the steering joint 3.
[0036] Specifically, as Figure 2 shown, it further includes a plurality of grooves 13 arranged circumferentially along the side wall of the lamp head 1.
[0037] Among them, the grooves 13 can provide positions for the formation of connections between the components on the lamp and the lamp head 1, enabling the lamp head 1 to accommodate the connections of more lamp components, and further expanding the application range of the lamp head connection structure.
[0038] The present utility model also discloses a lamp, as Figure 8 and Figure 9 shown in combination, including a lamp head 1, a lamp body 2, a steering joint 3, a telescopic connecting rod 4 and a support foot 5, and further including the above-mentioned lamp head connection structure. One end of the steering joint 3 is fixedly connected to the second connection groove 12, one end of the telescopic connecting rod 4 is fixedly connected to the lamp body 2, the other end of the steering joint 3 is movably connected to the other end of the telescopic connecting rod 4, and the support foot 5 is pivotally connected to the lamp body 2 and rotates into the groove 13 with the end pivotally connected to the lamp body 2 as the rotation center.
[0039] It should be noted that: equipped with this lamp head connection structure, a integral lamp structure can be formed when the lamp head 1 is connected to the lamp body 2, and it can be used as a lighting device such as a flashlight. Moreover, the connection tightness of the components of the integral lamp is high. When the lamp head 1 is separated from the lamp body 2 and works independently outside the lamp body 2, it can be used as a lighting device such as a fishing lamp or an atmosphere lamp, and the usage range of the lamp is extended; when the lamp head 1 is separated from the lamp body 2 and works independently outside the lamp body 2, the position of the lamp head 1 can be adjusted in multiple directions through the swivel joint 3 and the telescopic rod body, so that the lamp head 1 can irradiate in multiple different directions; the support feet 5 on the lamp that can be rotated to the lower part of the lamp to form a support structure can also be rotated into the groove 13 for storage and connected to the lamp head 1. When the lamp works in an integral structure, the support feet 5 rotated into the groove 13 can play a certain role in fixing the position of the lamp head 1.
[0040] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
