[0032] Reference Figures 1 to 6 For the waterproof power supply device of the utility model embodiment, including base assembly 100 and power supply assembly 200. Base assembly 100 includes mounting seat 110 and female needle seat 120, mounting seat 110 has installation surface 111, installation surface 111 is provided with installation through-hole 112, female needle seat 120 is rotationally arranged in installation through-hole 112 around the hole axis of installation through-hole 112, the outer peripheral surface of mounting seat 110 is provided with installation groove 113 around the hole axis of installation through-hole 112, one end of installation groove 113 is provided with the card block letout 1131;Power supply assembly 200 is detachably arranged in base assembly 100, power supply assembly 200 is provided with male needle seat 210, male needle seat 210 is provided with first accommodating hole 211, the side wall of first accommodating hole 211 is provided with card block part 212, power supply assembly 200 can be relative to base assembly 100 normal rotation and make card block part 212 from card block letout 1131 into installation groove 113, so that base assembly 100 and power supply assembly 200 enter the assembled state, and power supply assembly 200 can be relative to base assembly 100 reverse rotation and make card block part 212 from card block letout 1131 disengage installation groove 113, so that base assembly 100 and power supply assembly 200 enter the separation state;In the assembled state, base assembly 100 is embedded in first accommodating hole 211, installation surface 111 is opposite the bottom wall of first accommodating hole 211, male needle seat 210 and female needle seat 120 are inserted and cooperated and synchronously rotate, the outer peripheral surface of mounting seat 110 is in contact with the side wall of first accommodating hole 211;Wherein installation surface 111 and the bottom wall of first accommodating hole 211 are provided with reverse resistance structure, and the reverse resistance structure can generate the force that hinders the reverse rotation of power supply assembly 200.

[0033] By arranging the reverse resistance structure between the mounting surface 111 and the bottom wall of the first accommodating hole 211, the reverse resistance structure can limit the reverse disassembly of the power supply assembly 200 when the reverse force received by the power supply assembly 200 is small. Since the reverse resistance structure is arranged between the mounting surface 111 and the bottom wall of the first accommodating hole 211, neither the male needle seat 210 nor the mounting seat 110 will be radially deformed relative to the hole axis of the mounting through hole 112 during the forward rotation or reverse rotation of the power supply assembly 200, so that in the assembled state of the waterproof power supply device, the outer peripheral surface of the mounting seat 110 and the hole wall of the first accommodating hole 211 of the male needle seat 210 can be relatively closely contacted and matched without the need for assembly gaps, thereby further improving the waterproof effect of the waterproof power supply device.

[0034] In an embodiment, the reverse resistance structure includes a first blocking block 114 and a second blocking block 213, the first blocking block 114 is arranged on the mounting surface 111, and the second blocking block 213 is arranged on the bottom wall of the first accommodating hole 211. The first blocking block 114 and the second blocking block 213 are opposite along the circumference of the hole axis of the mounting through hole 112, and the mounting surface 111 and the bottom wall of the first accommodating hole 211 can be elastically deformed along the direction of the hole axis of the mounting through hole 112. When the rotating force of the power supply assembly 200 is small, the first blocking block 114 contacts the second blocking block 213, and a contact force is generated therebetween, which hinders the rotation of the power supply assembly 200. When the rotating force of the power supply assembly 200 is large, the first blocking block 114 passes over the second blocking block 213 by elastic deformation of the mounting seat 110 and the male needle seat 210, allowing the power supply assembly 200 to continue to rotate.

[0035] Specifically, the mounting seat 110 and the male needle seat 210 are both made of plastic material, so that the mounting surface 111 and the bottom wall of the first accommodating hole 211 can be elastically deformed.

[0036] In an embodiment, opposite sides of the first blocking block 114 are respectively provided with a forward rotation guide inclined surface 310 and a reverse rotation stop surface 320. The forward rotation guide inclined surface 310 is inclined relative to the hole axis of the mounting through hole 112, and the reverse rotation stop surface 320 is parallel to the hole axis of the mounting through hole 112. By arranging the forward rotation guide inclined surface 310, when the power supply assembly 200 is forward rotated, the first blocking block 114 can contact the second blocking block 213 through the forward rotation guide inclined surface 310. The component force of the contact force along the hole axis of the mounting hole can directly cause the mounting surface 111 and the bottom wall of the first accommodating hole 211 to be elastically deformed, so that when the power supply assembly 200 is forward rotated, the first blocking block 114 can more easily pass over the second blocking block to form a clamping connection. When the power supply assembly 200 is reversed, the first blocking block 114 contacts the second blocking block 213 through the reverse rotation stop surface 320, and a larger force is required to make the first blocking block 114 pass over the second blocking block 213.

[0037] Specifically, the opposite sides of the second blocking block 213 are also provided with a positive rotation guide slope 310 and a reverse rotation stop surface 320, further reducing the resistance when the first blocking block 114 passes through the second blocking block 213 during the positive rotation of the power assembly 200.

[0038] In the embodiment, the first blocking block 114 and the second blocking block 213 are both provided with three, all the first blocking blocks 114 are uniformly arranged around the hole axis of the mounting hole 112, and all the second blocking blocks 213 are uniformly arranged around the hole axis of the mounting hole 112. Uniformly arranging three first blocking blocks 114 and second blocking blocks 213, the resistance received at each place is relatively uniform when the power assembly 200 is reversed, and the use effect is better. It can be imagined that in other embodiments, the number of first blocking blocks 114 and second blocking blocks 213 can also be two, four or more, and those skilled in the art can choose according to actual needs.

[0039] In the embodiment, the mounting seat 110 is provided with a second accommodating hole 115, and the bottom wall of the second accommodating hole 115 forms the mounting surface 111. The second mounting hole is recessed, which facilitates the formation of a space for accommodating the first blocking block 114 and the second blocking block 213.

[0040] It can be imagined that in other embodiments, the reverse resistance structure can also be other structures, for example, the reverse resistance structure includes a friction block, the friction block is connected to the mounting surface 111, and the bottom wall of the first accommodating hole 211 is uneven. By contacting and rubbing the friction block with the bottom wall of the first accommodating hole 211, the power assembly 200 can receive a certain resistance when reversed.

[0041] In the embodiment, the bottom wall of the first accommodating hole 211 is provided with a first sealing ring 220, and the first sealing ring 220 abuts against one end of the mounting seat 110. By providing the first sealing ring 220 on the bottom wall of the first accommodating hole 211, the first sealing ring 220 can improve the waterproof sealing effect between the male needle seat 210 and the mounting seat 110, and since the first sealing ring 220 is located on the bottom wall of the first accommodating hole 211 and abuts against one end of the mounting seat 110, it does not affect the contact and cooperation of the side wall of the first accommodating hole 211 and the outer peripheral wall of the mounting seat 110.

[0042] In an embodiment, the mounting groove 113 comprises an arc segment 1132 and a spiral segment 1133, one end of the arc segment 1132 is butted with one end of the spiral segment 1133, the other end of the spiral segment 1133 has a clamping block clearance 1131, the clamping block clearance 1131 is located at one side of the spiral segment 1133 along the hole axis direction of the mounting through hole 112. When assembling, the power supply assembly 200 is close to the base assembly 100, so that the clamping block part 212 is aligned to enter the clamping block clearance 1131, the power supply assembly 200 is rotated so that the clamping block part 212 passes through the clamping block clearance and slides along the spiral segment 1133 and the arc segment 1132, and finally the power supply assembly 200 is assembled with the mounting assembly in place. By arranging the spiral segment 1133, when the power supply assembly 200 rotates, a small amount of displacement along the hole axis direction of the mounting through hole 112 can occur, which facilitates the abutting contact between the power supply assembly 200 and the base assembly 100, and improves the waterproof sealing effect.

[0043] In an embodiment, the hole wall of the mounting through hole 112 is provided with an upper limiting block 116 and a lower limiting ring 117, the upper limiting block 116 and the lower limiting ring 117 are arranged along the hole axis direction of the mounting through hole 112, the lower limiting ring 117 is arranged around the hole axis of the mounting through hole 112, the outer peripheral wall of the female needle seat 120 is provided with a connecting ring 121 around the hole axis of the mounting through hole 112, and the connecting ring 121 is located between the upper limiting block 116 and the lower limiting ring 117. The above structure allows the female needle seat 120 to rotate around the hole axis of the mounting through hole 112 relative to the mounting base 110, and limits the movement of the female needle seat 120 relative to the mounting base 110 along the hole axis direction of the mounting through hole 112, and the structure is relatively simple and the rotary connection is relatively stable.

[0044] In an embodiment, the connecting ring 121 is provided with a mounting gap 1211 for the upper limiting block 116 to pass through. The mounting base 110 and the female needle seat 120 are respectively produced and then assembled together. When assembling, the female needle seat 120 is moved along the hole axis direction of the mounting through hole 112, so that the upper limiting block 116 can pass through the mounting gap 1211 to overcome the connecting ring 121, and then the female needle seat 120 is rotated, so that the mounting gap 1211 can avoid the upper limiting block 116, to realize the assembly of the two, and the female needle seat 120 can rotate relative to the mounting base 110.

[0045] It should be understood that when the waterproof power supply device is in use, the upper limiting block 116 is located above the connecting ring 121, so that the connecting ring 121 can be maintained between the upper limiting block 116 and the lower limiting block under the action of gravity.

[0046] In the embodiment, the power supply assembly 200 further comprises a protective cover 230, the protective cover 230 has a third accommodating hole 231, the male needle seat 210 is connected to the protective cover 230 and seals the aperture of the third accommodating hole 231, and the male needle seat 210 is clamped with the protective cover 230. The protective cover 230 is arranged, the protective cover 230 can seal one side of the male needle seat 210, the electrical components can be installed in the third accommodating hole 231, and the sealing waterproof effect is good.

[0047] Specifically, the outer periphery of the male needle seat 210 is further provided with a second sealing ring 240, the outer periphery of the male needle seat 210 is embedded in the third accommodating hole 231, and the second sealing ring 240 abuts against the hole wall of the third accommodating hole 231. The protective cover 230 is clamped with the male needle seat 210, and the assembly is relatively simple.

[0048] Specifically, the male needle seat 210 is provided with a male conductor needle, and the female needle seat 120 is provided with a needle hole for installing a female conductor needle. The male conductor needle can be inserted and matched with the female conductor needle.

[0049] Specifically, the base assembly 100 further comprises a third sealing ring 130, and the third sealing ring 130 is connected to the lower side of the mounting seat 110. The mounting seat 110 can be locked to the lamp by screws, at this time, the mounting seat 110 abuts against the lamp through the third sealing ring 130, and the waterproof sealing effect is further improved.

[0050] Specifically, the mounting groove 113 is provided with three and is uniformly arranged around the hole axis of the mounting through hole 112, and the clamping block part 212 is also provided with three and is uniformly arranged around the hole axis of the mounting through hole 112.

[0051] Specifically, the mounting seat 110 is provided with a barrel part on the mounting surface 111, and the barrel part forms the mounting through hole 112.

[0052] Specifically, when the waterproof power supply device is in a separated state, the power supply assembly 200 is close to the base assembly 100, the clamping block part 212 is aligned with the clamping block accommodation port 1131, then the power supply assembly 200 is rotated in a normal direction, so that the power supply assembly 200 is tightly assembled with the base assembly 100, the waterproof power supply device enters an assembled state, at this time, the first blocking block 114 and the second blocking block 213 are clamped and matched to limit the reverse rotation of the power supply assembly 200, and the clamping block part 212 is matched with the mounting groove 113 to limit the position of the power supply assembly 200 along the hole axis of the mounting through hole 112. When a small reverse force is applied to the power supply assembly 200, the first blocking block 114 and the second blocking block 213 are clamped and matched to limit the reverse rotation of the power supply assembly 200; when a large reverse force is applied to the power supply assembly 200, the first blocking block 114 passes through the second blocking block 213, finally the clamping block part 212 is separated from the mounting groove 113, then the power supply assembly 200 can be away from the base assembly 100, and the disassembly is completed.
