[0017] As in Fig. 1 to Fig. As shown in Figure 6, the present application provides a tube body structure of a lamp. The exemplary embodiment of the tube body structure of the present application includes a tube 10 and a support rod 20. The tube 10 has an installation cavity 11 into which the support rod 20 is inserted. The support rod 20 includes a support core 21 and a peripheral adhesive layer 22 applied to the outside of the support core 21.

[0018] By applying the technical solution of this embodiment, the tubular body structure includes a hose 10 and a support rod 20 disposed in the installation cavity 11 of the hose 10. The support rod 20 can support the hose 10 from the inside, thereby ensuring the bending and torsion action of the hose 10 while improving the structural strength of the tubular body structure, so that the hose 10 can be held in a predetermined position after bending under the action of the support rod 20. Specifically, the support rod 20 includes a support core 21 and a circumferential adhesive layer 22 applied to the outside of the support core 21. The support core 21 plays a role in improving the overall structural strength and durability of the tubular body structure.The circumferential adhesive layer 22 can prevent wear, improve the user's operating feel when bending and twisting the hose 10, and extend the service life of the support core 21. Therefore, the technical solution of this embodiment can effectively solve the problem in the prior art that the hose cannot be stably positioned at the expected position.

[0019] It should be noted that this application relates to a lamp tube body structure and a lamp. In describing the technical solution of the present application, the terms "front end" and "rear end" used refer to an end closer to the lamp body 60 of the lamp and an end farther from the lamp body 60 of the lamp, respectively.

[0020] Specifically, in this embodiment, the support core 21 is a metal inner core. Metal materials exhibit high structural strength, a certain degree of ductility, and wear resistance. The use of metal materials to manufacture the support core 21 can effectively improve the service life of the tube body structure by ensuring the bending and twisting ability of the hose 10.

[0021] The material of the metal inner core is aluminum, iron, aluminum alloy, or stainless steel, as long as the metal inner core has flexible deformation capability and improves the rotational durability and positional stability after bending and rotating the hose 10. Preferably, the material of the metal inner core is iron.

[0022] In this embodiment, the material of the circumferential adhesive layer 22 is rubber or plastic. Rubber and plastic exhibit good wear resistance, chemical stability, etc., and can ensure the service life of the support rod 20. The circumferential adhesive layer 22 can prevent wear of the metal inner core, thereby further extending the service life of the support rod 20 and thus the service life of the tube body structure. Preferably, the material of the circumferential adhesive layer 22 can be TPU (thermoplastic polyurethane elastic rubber) or TPE (thermoplastic elastomer).

[0023] As in Fig. 1 to Fig. As shown in Figure 6, the support rod 20 has a circular cross-section. Compared to other cross-sectional shapes, the circular cross-sectional shape facilitates bending of the support rod 20 along with the hose 10, thereby reducing the difficulty for the user in bending and twisting the hose 10.

[0024] As in Fig. 2 and Fig. As shown in Figure 3, the material of the support core 21 is iron, and the material of the peripheral adhesive layer 22 is 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. 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. The diameter D1 of the support rod 20 may preferably 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.

[0025] In the case where the material of the support core 21 is iron, the material of the circumferential adhesive layer 22 is TPU, the diameter D1 of the support rod 20 is 2.4 mm, and the diameter D2 of the support core 21 is 1.2 mm, a torsion test is performed on a tube body structure in which the tube 10 with the support rod 20 arranged therein is continuously bent by 90° (the bending frequency is 10 times per minute). The support core 21 will not break until it is bent 650 times, which is far more than the 300 times required by the bending standard.

[0026] As in Fig. 2 to Fig. 6, the installation cavity 11 penetrates the hose 10 in the axial direction. The tube body structure further includes a first connecting element 30 arranged at a front end of the hose 10 and blocking the support rod 20, and a second connecting element 40 arranged at a rear end of the hose 10 and blocking the support rod 20. Since the installation cavity 11 extends through the hose 10 in the axial direction, when assembling the tube body structure, it is only necessary to insert the support rod 20 into the hose 10 and then install the first connecting element 30 and the second connecting element 40 at both ends of the hose 10, respectively. This offers the advantage of simple operation. At this time, the first connecting element 30 and the second connecting element 40 can be connected to the hose 10 by riveting.The first connecting element 30 and the second connecting element 40 can establish the connection between the hose 10 and other structures and at the same time limit the position of the support rod 20.

[0027] In particular, the front end of the first connecting element 30 has a connecting port 31. The connecting port 31 is provided with external threads. The external threads can be connected to the internal threads on the lamp body 60 to connect the lamp body 60 to the front end of the hose 10.

[0028] As in Fig. 1 to Fig. 3 and Fig. 5, the tubular body structure also includes a telescopic sleeve 50 into which the hose 10 is movably inserted, the hose having a first extended position where the hose protrudes from the telescopic sleeve 50 and a first retracted position where the hose is retracted into the telescopic sleeve 50. When the hose 10 is in the first extended position, the second connecting element 40 is in abutting engagement with the telescopic sleeve 50 to prevent the hose 10 from detaching from the telescopic sleeve 50. The telescopic sleeve 50 itself can be lengthened or shortened to facilitate the user's storage of the lamp with the tubular body structure according to this embodiment, the hose 10 having the first extended position where the hose protrudes from the telescopic sleeve 50 and the first retracted position where the hose is retracted into the telescopic sleeve 50.It is possible to move the hose 10 into the first retracted position when the user is no longer using the lamp, thus reducing the overall length of the lamp and making it easier for the user to store the lamp.

[0029] It should be noted that the above-mentioned “first extended position” and “first retracted position” both refer to the limit position of the movement of the hose 10 relative to the telescopic sleeve 50, wherein the first extended position represents the position in which the hose 10 has the greatest extended length relative to the telescopic sleeve 50, and the first retracted position represents the position in which the hose has the shortest extended length relative to the telescopic sleeve 50.

[0030] As in Fig. 2 to Fig. As shown in Figure 4, the telescopic sleeve 50 comprises a first tubular body 51 and a second tubular body 52 that are nested within one another. The first tubular body 51 is located within the second tubular body 52. ​​The first tubular body 51 has a second extended position, where the first tubular body protrudes from the second tubular body 52, and a second retracted position, where the first tubular body is retracted into the second tubular body 52. ​​The first tubular body 51 has a locking projection 511 at its rear end, and the second tubular body 52 has a locking recess 521 at its front end. When the first tube body 51 is in the second extended position, the locking projection 511 and the locking recess 521 are in abutting cooperation to prevent the first tube body 51 from detaching from the second tube body 52.The telescopic sleeve 50 comprises a plurality of nested tube bodies, wherein the first tube body 51 is the innermost tube body and the second tube body 52 is a tube body located outside the first tube body 51 and adjacent to the first tube body 51. When the first tube body 51 is in the second extended position, the locking projection 511 and the locking recess 521 are in abutting cooperation, so that the first tube body 51 can be stably held in the second extended position without being separated from the second tube body 52, thereby ensuring the structural stability of the telescopic sleeve 50.

[0031] It should be noted that the above-mentioned “rear end of the first tube body 51” refers to a portion 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 portion of the tube body at the front end of the first tube body 52.

[0032] In particular, as in Fig. 4, in this embodiment, the tube diameter of the first tube body 51 gradually increases from front to back, so that during the process of the first tube body 51 being projected relative to the second tube body 52, the first tube body 51 and the second tube body 52 gradually compress each other. The second tube body 52 includes a main body portion 523 on which a locking recess 521 is provided, and a shrink portion 522 provided at the front end of the main body portion 523. When the first tube body 51 is in the second extension position, the shrink portion 522 is pressed against the side wall of the first tube body 51, so that the first tube body 51 can be stably held in the second extension position.

[0033] As in Fig. 3, 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 element 40 is in abutting engagement with the connecting sleeve 53 to prevent the hose 10 from detaching forward from the telescopic sleeve 50.

[0034] As in Fig. 7 to Fig. As shown in Figure 9, the present application also provides a lamp. The embodiment of the lamp of the present application includes a tubular body structure, a lamp body 60 disposed at a front end of the tubular body structure, and a handle 70 disposed at a rear end of the tubular body structure, wherein the tubular body structure is the aforementioned tubular body structure. With the aforementioned tubular body structure, the problem in the prior art that the tube cannot be stably positioned at the expected position can be effectively solved. Therefore, the lamp having the aforementioned tubular body structure also has the aforementioned advantages.

[0035] As in Fig.As shown in Figure 9, the rear end of the lamp body 60 is provided with a connecting sleeve 61. The inner surface of the connecting sleeve 61 is provided with an internal thread. The connecting sleeve 61 can be screwed to the connecting connector 31 to attach the lamp body 60 to the front end of the hose 10.
