Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0038] like Figures 1 to 6 As shown, the present application provides a tube structure for a lamp. The embodiment of the tube structure of the present application includes a hose 10 and a support rod 20. The hose 10 has an installation cavity 11; the support rod 20 is disposed in the installation cavity 11 and includes a support inner core 21 and a covering rubber layer 22 disposed on the outer side of the support inner core 21.

[0039] Using the technical solution of this embodiment, the tube structure includes a hose 10 and a support rod 20 disposed within the mounting cavity 11 of the hose 10. The support rod 20 can support the hose 10 from the inside, ensuring the bending and rotation effect of the hose 10 while improving the structural strength of the tube structure, so that after the hose 10 is bent, it can be maintained in a predetermined position under the action of the support rod 20. Specifically, the support rod 20 includes a supporting inner core 21 and a covering rubber layer 22 sleeved on the outside of the supporting inner core 21. The supporting inner core 21 serves to improve the overall structural strength and service life of the tube structure, and the covering rubber layer 22 can have an anti-wear effect, improving the user's operating feel when bending and rotating the hose 10 and extending the service life of the supporting inner core 21. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the hose cannot be stably positioned in the expected position.

[0040] It should be noted that the present application relates to a tube structure of a lamp and a lamp. When describing the technical solution of the present application, the "front end" and "rear end" used refer to one end of the lamp body 60 close to the lamp and the other end of the lamp body 60 away from the lamp, respectively.

[0041] Specifically, in this embodiment, the support core 21 is a metal core. Metal has high structural strength, certain ductility and wear resistance. Using metal to make the support core 21 can effectively increase the service life of the hose body structure while ensuring the bending and rotation capabilities of the hose 10.

[0042] The metal inner core is made of aluminum, iron, aluminum alloy or stainless steel, as long as it has flexible deformation capability and can extend the rotation life of the hose 10 and the position stability after bending and rotation. Preferably, the metal inner core is made of iron.

[0043] In this embodiment, the coating layer 22 is made of rubber or plastic. Rubber and plastic have excellent wear resistance and chemical stability, ensuring the service life of the support rod 20. The coating layer 22 prevents wear of the metal core, further extending the service life of the support rod 20 and, consequently, the service life of the tubular structure. Preferably, the coating layer 22 is made of TPU (thermoplastic polyurethane elastomer) or TPE (thermoplastic elastomer).

[0044] like Figures 1 to 6 As shown, the cross section of the support rod 20 is circular. Compared with other cross-sectional shapes, the circular cross-sectional shape makes it easier for the support rod 20 to bend together with the hose 10, reducing the difficulty of the user's operation of bending and rotating the hose 10.

[0045] like Figure 2 and Figure 3 As shown, the support core 21 is made of iron, the covering rubber layer 22 is made of TPU, the diameter D1 of the support rod 20 is greater than or equal to 1.0 mm and less than or equal to 4.0 mm, and the diameter D2 of the support core 21 is greater than or equal to 0.5 mm and less than or equal to 3.0 mm. Preferably, the diameter D1 of the support rod 20 can be 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, 3.2 mm, 3.5 mm, 3.8 mm, or 4.0 mm; the diameter D2 of the support core 21 can be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.5 mm, 2.8 mm, or 3.0 mm.

[0046] A rotation test was conducted on a tube structure in which the support core 21 was made of iron, the coating rubber layer 22 was made of TPU, the diameter D1 of the support rod 20 was 2.4 mm, and the diameter D2 of the support core 21 was 1.2 mm. The hose 10 with the support rod 20 inside was bent 90° continuously (at a bending frequency of 10 times / min). The support core 21 only broke after 650 bends, which far exceeded the 300 times required by the bending standard.

[0047] like Figures 2 to 6 As shown, the installation cavity 11 passes through the hose 10 in the axial direction, and the tube structure also includes a first connector 30 provided at the front end of the hose 10 and blocking the support rod 20, and a second connector 40 provided at the rear end of the hose 10 and blocking the support rod 20. The installation cavity 11 passes through the hose 10 in the axial direction. When assembling the tube structure, it is only necessary to insert the support rod 20 into the hose 10, and then install the first connector 30 and the second connector 40 at both ends of the hose 10, which has the advantage of simple operation. The first connector 30 and the second connector 40 can be connected to the hose 10 by riveting. The first connector 30 and the second connector 40 can realize the connection between the hose 10 and other structures, and at the same time realize the limiting of the support rod 20.

[0048] Specifically, the front end of the first connector 30 has a connector 31 , which is provided with an external thread that can be connected to the internal thread on the lamp body 60 , thereby connecting the lamp body 60 to the front end of the hose 10 .

[0049] like Figures 1 to 3 as well as Figure 5 As shown, the tubular structure further includes a telescopic sleeve 50. The hose 10 is movably disposed within the telescopic sleeve 50 and has a first extended position extending from the telescopic sleeve 50 and a first retracted position retracted into the telescopic sleeve 50. When the hose 10 is in the first extended position, the second connector 40 cooperates with a stop on the telescopic sleeve 50 to prevent the hose 10 from being removed from the telescopic sleeve 50. The telescopic sleeve 50 itself can be extended or shortened, making it easier for users to store the lamp having the tubular structure of this embodiment. The hose 10 has a first extended position extending from the telescopic sleeve 50 and a first retracted position retracted into the telescopic sleeve 50. When the user is no longer using the lamp, the hose 10 can be placed in the first retracted position, thereby reducing the overall length of the lamp and making it easier for users to store the lamp.

[0050] It should be noted that the above-mentioned "first extended position" and "first retracted position" both refer to the extreme positions of movement of the hose 10 relative to the telescopic sleeve 50, wherein the first extended position is the position where the hose 10 extends the longest relative to the telescopic sleeve 50, and the first retracted position refers to the position where the hose 10 extends the shortest relative to the telescopic sleeve 50.

[0051] like Figures 2 to 4 As shown, the telescopic sleeve 50 includes a first tube body 51 and a second tube body 52 that are nested together. The first tube body 51 is located in the second tube body 52. ​​The first tube body 51 has a second extended position extending from the second tube body 52 and a second retracted position retracted into the second tube body 52. ​​A retaining protrusion 511 is provided at the rear end of the first tube body 51, and a retaining recess 521 is provided at the front end of the second tube body 52. ​​When the first tube body 51 is in the second extended position, the retaining protrusion 511 and the retaining recess 521 are engaged to prevent the first tube body 51 from separating from the second tube body 52. Among them, the telescopic sleeve 50 includes multiple tube bodies arranged in a nested manner, the first tube body 51 is the innermost tube body, and the second tube body 52 is the tube body located outside the first tube body 51 and arranged adjacent to the first tube body 51. When the first tube body 51 is in the second extended position, the retaining protrusion 511 and the retaining recess 521 cooperate with each other to allow the first tube body 51 to be stably maintained in the second extended position without separating from the second tube body 52, thereby ensuring the structural stability of the telescopic sleeve 50.

[0052] It should be noted that the above-mentioned “rear end of the first tube body 51 ” refers to a section of the tube body at the rear end of the first tube body 51 , and the above-mentioned “front end of the second tube body 52 ” refers to a section of the tube body at the front end of the second tube body 52 .

[0053] Specifically, if Figure 4 As shown, in this embodiment, the diameter of the first tube body 51 gradually increases from front to back, so that the first tube body 51 and the second tube body 52 gradually abut against each other as the first tube body 51 extends relative to the second tube body 52. ​​The second tube body 52 includes a main body section 523 and a contraction section 522 disposed at the front end of the main body section 523. The retaining recess 521 is disposed on the main body section 523. When the first tube body 51 is in the second extended position, the contraction section 522 abuts against the side wall of the first tube body 51, allowing the first tube body 51 to remain stably in the second extended position.

[0054] like Figure 3 As shown, the telescopic sleeve 50 also includes a connecting sleeve 53 connected to the front end of the first tube body 51 and extending into the first tube body 51. The hose 10 is movably inserted into the connecting sleeve 53. When the hose 10 is in the first extended position, the second connecting member 40 cooperates with the connecting sleeve 53 to prevent the hose 10 from detaching forward from the telescopic sleeve 50.

[0055] like Figures 7 to 9 As shown, the present application further provides a lamp. An embodiment of the lamp of the present application includes a tube structure, a lamp body 60 disposed at the front end of the tube structure, and a handle 70 disposed at the rear end of the tube structure. The tube structure is the tube structure described above. The above-mentioned tube structure can effectively solve the problem in the related art that the hose cannot be stably positioned in the intended position. The lamp having the above-mentioned tube structure also has the above-mentioned advantages.

[0056] like Figure 9 As shown, a connecting sleeve 61 is provided at the rear end of the lamp body 60 , and an internal thread is provided on the inner surface of the connecting sleeve 61 . The connecting sleeve 61 can be threadedly matched with the connector 31 to connect the lamp body 60 to the front end of the hose 10 .

[0057] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0058] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0059] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
