[0034] Example

[0035] Combination Figures 1 to 12As shown, this embodiment provides a mobile lamp for convenient replacement of lamp caps, comprising a handle and a lamp body; the handle and the lamp body are connected via a connection structure that can be quickly disassembled; the connection structure comprises an installation cavity 1 and an installation portion 6 that can be respectively arranged on the connection ends of the handle and the lamp body;

[0036] A clamping portion 9 and a first limiting portion 4 are provided on the outer circumferential side of the mounting portion 6; a positioning groove 5 adapted to the clamping portion 9, a second limiting portion 10 cooperating with the first limiting portion 4, and a positioning portion 3 for positioning the clamping portion 9 in the circumferential direction are provided in the mounting cavity 1; the first limiting portion 4 and / or the second limiting portion 10 are elastic; the positioning portion 3 and the limiting portion can enable the end face of the mounting portion 6 and the conductive part on the bottom surface of the mounting cavity 1 to be positioned and connected accordingly.

[0037] The handle and the lamp body are connected by a connection structure that can be quickly disassembled and assembled, so that the lamp body can be quickly disassembled and assembled to replace the lamp body with different lighting functions, so that it can be applied to more usage scenarios and meet the user's application needs.

[0038] Specifically, in this embodiment, Figures 1 to 6 As shown, the installation cavity 1 is arranged on the outer shell of the plastic handle and is a cylindrical cavity, in which a protrusion 2 is arranged, and a limiting wall is arranged at one end to form the positioning portion 3; the protrusion 3 is connected to the limiting wall in an L shape, and the protrusion 2, the positioning portion 3 and the bottom end surface of the installation cavity 1 form the positioning groove 5 which is open on one side along the circumferential direction. The installation portion 6 is arranged on the plastic base 13 of the lamp body, and includes a first installation portion 7 and a second installation portion 8 connected to the first installation portion 7 and having an outer diameter smaller than the first installation portion 7; the outer diameter of the second installation portion 8 is not greater than the inner diameter of the protrusion 3, and the height of the second installation portion 8 is not less than the distance from the upper end surface of the protrusion 3 to the bottom end surface of the installation cavity 1, so that the second installation portion 8 can enter between the upper end surface of the protrusion 3 and the bottom end surface of the installation cavity 1 along the axial direction; the clamping portion 9 is arranged on the second installation portion 8 protruding outward; the first limiting portion 4 is arranged on the first installation portion 7. The positioning portion 3 is used to position the clamping portion 9 in the circumferential direction when it rotates in the positioning groove 5, so that the end face of the mounting portion 6 and the conductive member on the bottom surface of the mounting cavity 1 are accurately connected; when the clamping portion 9 rotates in the positioning groove 5, the first limiting portion 4 and the second limiting portion 10 interact with each other and then deform, so that the second limiting portion 10 passes over the first limiting portion 4; the first limiting portion 4 can limit the reverse rotation of the second limiting portion 10, so as to avoid the clamping portion 9 from rotating in the reverse direction without the action of external force, causing the conductive members to deviate from each other and fail to accurately conduct and connect.

[0039] Specifically, in this embodiment, if Figure 2 and Figure 4 As shown, the first limiting portion 4 and the second limiting portion 10 are the first rib and the second rib arranged along the axial direction; the first rib is arranged on the first mounting portion 7, and the second rib is arranged between the upper end surface of the protrusion 3 and the top end surface of the mounting cavity 1. The first rib and the second rib are semicircular arc-shaped, so that the second rib can pass over the first rib more smoothly, and the plastic rib itself has a certain elasticity. Figure 1 and Figure 4 As shown, an elastic conductive contact 11 is provided on the end face of the mounting portion 6; a conductive contact 12 adapted to the conductive contact 11 is provided at the bottom of the mounting cavity 1; after the mounting portion 6 is inserted into the mounting cavity 1, the conductive contact 11 will elastically contract so that the clamping portion 9 can enter the open end of the positioning groove 5 and then rotate. When the clamping portion 9 is rotated into place, the conductive contact 11 just abuts against the conductive contact 12 to achieve conduction.

[0040] Preferably, if Figures 1 to 4 As shown, the outer diameter and circumferential dimension of one of the clamping parts 9 are smaller than the corresponding dimension of the other clamping part 9; and the alignment groove 5 is adapted to the clamping part 9. This is to prevent the positive and negative poles of the conductive part from being reversely connected or not being aligned, resulting in the circuit not being connected. Figure 1 and Figure 2 As shown, a third limiting portion 30 is provided in the installation cavity, which is arranged at the opening side of the positioning groove adapted to the clamping portion with smaller size in the circumferential direction. The limiting portion is arranged so that the clamping portion 9 with larger size cannot enter the opening side of the positioning groove with smaller size along the axial direction, thereby realizing foolproofing of the clamping portions and the positioning grooves of different sizes, and further avoiding reverse connection of the positive and negative poles of the conductive parts.

[0041] In this embodiment, the lamp body includes a base body 13 and a lamp head assembly rotatably connected to the base body 13; the base body 13 is provided with the mounting portion 6.

So that the lamp body can rotate with a gear sense relative to the seat body 13.

[0042] Based on the above embodiments, Figure 8 and Fig.11 As shown, the other end of the first mounting seat 19 is provided with a second mounting groove 20, and the two inner sides of the second mounting groove 20 are provided with a first rotating shaft 21; one end of the second mounting seat 22 connected to the lamp holder 18 is provided with a first rotating groove 26 for accommodating the first rotating shaft 21; a first annular groove is provided on the side wall of one of the first rotating shaft 21 and the first rotating groove 26, and the other is provided with a first annular protrusion adapted to the first annular groove. Alternatively, the first rotating shaft 21 is provided with a first annular groove, and a damping member is provided on the annular groove. The damping member can be a silicone ring, which can increase the friction resistance between the first rotating shaft 21 and the first rotating groove 26 to achieve non-gear rotation between the first mounting seat 19 and the second mounting seat 22.

[0043] Based on the above embodiments, Figures 9 to 11 As shown, a third mounting seat 23 is also provided on the lamp body, and a second rotating shaft 24 is provided at one end of the third mounting seat 23, and a second rotating groove 25 for accommodating the second rotating shaft 24 is provided at the other end of the second mounting seat 22; a second annular groove is provided on the side wall of one of the second rotating shaft 24 and the first rotating groove, and the other is provided with a second annular protrusion 2 matched with the second annular groove; at least one first limiting protrusion 27 is provided on the second rotating shaft 24, and a second limiting protrusion matched with the first limiting protrusion 27 is provided on the second rotating groove 25 to limit the rotation angle of the connecting member.
