[0028] Below, a detachable hidden woven tape head lamp according to an embodiment of the present utility model is described with reference to the drawings.

[0029] Referring to Figure 1 and Figure 2 , a detachable hidden woven tape head lamp according to an embodiment of the present utility model comprises a head lamp main body 1 and a woven tape 2, the head lamp main body 1 comprises a back plate 3, a light source assembly 4 and a silica gel cover 5. The silica gel cover 5 is a cover body prepared by using silica gel as material. The light source assembly 4 can comprise LED lamp beads, a PCB-A board, a power supply, a lens 6 and a shell 7, etc., the LED lamp beads and the PCB-A board can be in an installation space surrounded by the lens 6 and the shell 7.

[0030] The back plate 3 is connected with the shell 7 of the light source assembly 4, a recess 8 is formed on the side of the back plate 3 away from the light source assembly 4, and two tape passing holes 9 are respectively located at the two ends of the recess 8 in the extension direction, referring to Figure 3 the perspective view, the two tape passing holes 9 are located at the left and right ends of the recess 8. The woven tape 2 passes into the two tape passing holes 9, and the woven tape 2 between the two tape passing holes 9 is located in the recess 8. The woven tape 2 can be selected as an elastic woven tape to better fix the head lamp main body 1 on the head 12 of the user.

[0031] The silica gel cover 5 completely covers the side of the back plate 3 away from the light source assembly 4, and the back plate 3 further forms a plurality of positioning through holes 10, referring to Figure 3 the perspective view, the positioning through holes 10 are arranged on the upper and lower sides of the back plate 3. Each positioning protrusion 11 of the silica gel cover 5 is clamped in the corresponding positioning through hole 10 of the back plate 3, and the connection of the silica gel cover 5 and the back plate 3 is realized by the cooperation of the positioning protrusion 11 and the positioning through hole 10.

[0032] The positioning protrusions 11 comprise head portions 12 extending out of the positioning through holes 10, and root portions 13 connecting the head portions 12 with the silica gel cover 5. The cross section of each of the head portions 12 near the end of the root portion 13 is larger than that of the corresponding positioning through hole 10. Since the positioning protrusions 11 are made of silica gel material, they can be elastically deformed during the process of engaging the positioning protrusions 11 with the positioning through holes 10. Therefore, the cross section of each of the head portions 12 near the end of the root portion 13 being larger than that of the corresponding positioning through hole 10 does not result in the positioning protrusions 11 failing to engage with the positioning through holes 10. Similarly, during the process of removing the silica gel cover 5 from the back plate 3, the positioning protrusions 11 can also be elastically deformed, and the positioning protrusions 11 are separated from the positioning through holes 10.

[0033] The belt passing hole 9 is formed with an opening 14 for the belt 2 to extend into the belt passing hole 9 transversely. The opening 14 facilitates the installation and removal of the belt 2.

[0034] Now referring to Figures 5 to 8 In the present embodiment, the back plate 3 is formed with two oppositely arranged mounting seats 15, and the inner circumferential wall of each of the mounting seats 15 is circumferentially formed with a plurality of positioning grooves 16. The housing 7 is located between the two mounting seats 15, and the two opposite sides of the housing 7 are formed with two rotating shaft portions 17 extending into the corresponding mounting seats 15 respectively, and the outer periphery of each of the rotating shaft portions 17 is formed with a positioning protrusion 18. The light source assembly 4 further comprises two damping rings 19 respectively sleeved on the corresponding rotating shaft portions 17, and the inner ring of each of the damping rings 19 is formed with a recess 20 cooperating with the positioning protrusion 18, and the outer ring of each of the damping rings 19 is formed with a plurality of strip-shaped protrusions 21 cooperating with the corresponding positioning grooves 16 of the mounting seat 15. The damping ring 19 is further formed with a plurality of holes 22 providing space for the deformation of each of the strip-shaped protrusions 21 towards the inner ring. During the rotation of the housing 7 relative to the back plate 3, the damping ring 19 does not rotate relative to the rotating shaft portion 17, but rotates relative to the mounting seat 15, and each of the strip-shaped protrusions 21 deforms towards the inner ring under the action of external force, and each of the strip-shaped protrusions 21 is separated from the corresponding positioning groove 16 cooperating before the rotation, and after rotating to a corresponding angle, each of the strip-shaped protrusions 21 cooperates with the corresponding positioning groove 16 to "lock" the angle between the housing 7 and the back plate 3, and further "lock" the direction of the light emitted by the light source assembly 4. Therefore, the present embodiment is simple and convenient for adjusting the light emitting direction of the hidden detachable belt head lamp.

[0035] Specifically, a threaded hole 23 can be formed at the center of the free end of each of the rotating shaft portions 17. The light source assembly 4 can further comprise a bolt 24 cooperating with the threaded hole 23, and the head of the bolt 24 can abut against the side of the mounting seat 15 facing away from the housing 7. Preferably, the diameter of the head of the bolt 24 is larger than that of the inner ring of the damping ring 19. The bolt 24 can effectively prevent the housing 7 and the damping ring 19 from accidentally falling off the back plate 3.

[0036] See now Figure 9 and Figure 10 The elongated protrusions 21 of the damping ring 19 extend axially and are arranged in a ring array. The edges of the cross-section of the elongated protrusions 21 of the damping ring 19 are arc-shaped and symmetrical from left to right. The holes 22 of the damping ring 19 are also arranged in a ring array, and the radius of the virtual circle in which all holes 22 are located is slightly smaller than the radius of the virtual circle in which all elongated protrusions 21 are located, that is, each hole is located close to the elongated protrusions 21.

[0037] Compared to traditional headlamps with detachable webbing, this embodiment features a detachable, concealed webbing headlamp. During use, the silicone cover increases the contact area between the headlamp body and the user's head, effectively solving the problem of the headlamp body easily shifting left and right relative to the webbing due to the user's head movement. Furthermore, even if the webbing tightens excessively, the silicone cover isolates the back panel from the user's head, and its elasticity greatly reduces user discomfort.
