The lamp of the utility model achieves the effect of quick fixing and quick power connection by connecting the locking device. The specific embodiments of the utility model will be described in detail below.

[0038] Example 1

[0039] Please refer to Figures 1 to 3 This embodiment provides a locking device that can be quickly installed and locked, including: a base 1, a locking member 2 and a plug body 3.

[0040] Specifically, the plug body 3 is provided with a first guide portion 32 and a second guide portion 33, the first guide portion 32 is used to guide the plug body 3 to be inserted into the base 1 along the first direction, and the second guide portion 33 is used to guide the plug body 3 to move in the second direction and the third direction during the process of the plug body 3 being inserted into the base 1 along the first direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0041] It can be understood that the perpendicular relationship between the first direction, the second direction and the third direction can refer to the relationship between the three axes x, y and z. The second guide portion 33 guides the movement of the plug body 3 in the second direction and the third direction. It can be understood that the second guide portion 33 can limit the movement of the plug body 3 in the second direction and the third direction, that is, the plug body 3 is guided in the first direction by the setting of the first guide portion 32, and is limited in the second direction and the third direction by the setting of the second guide portion 33, so that when the plug body 3 is inserted into the base 1, it can be quickly positioned and quickly guided for installation by the first guide portion 32, and under the limiting action of the second guide portion 33, it has good stability during and after the installation process.

[0042] Furthermore, the locking member 2 is partially located on the plug body 3 and partially located on the base 1. The locking member 3 is used to lock the plug body 3 on the base 1 after the first guide portion 32 and the second guide portion 33 complete the guidance. After the locking member 2 locks the plug body 3, the plug body 3 is not easily separated from the base 1, thereby improving the installation stability of the plug body 3.

[0043] In one embodiment, please refer to Figure 3 The plug body 3 protrudes in the second direction to form a first guide portion 32 , and the first guide portion 32 and the second guide portion 33 are stacked along the second direction so that the first guide portion 32 guides the movement of the plug body 3 before the second guide portion 33 .

[0044] For details, please refer to Figure 4 and Figure 5 , the first guide portion 32 may include a rectangular protrusion 321 formed by the plug body 3 protruding in the second direction, the second guide portion 33 may include a dovetail structure 331 arranged on both sides of the plug body 3, the rectangular protrusion 321 and the dovetail structure 331 are stacked along the second direction, and the distance between the dovetail structures 331 on both sides decreases along the first direction to form a trapezoidal structure or a V-shaped structure (a trapezoidal structure is shown in the figure). Exemplarily, the base 1 includes a guide slot 11, and the guide slot 11 specifically includes a dovetail groove 111 adapted to the dovetail structure 331, and a rectangular groove 112 adapted to the rectangular protrusion 321.

[0045] It can be understood that, since the structure of the dovetail groove 111 is adapted to the dovetail structure 331, the spacing between the dovetail grooves 111 on both sides also gradually decreases along the first direction, so that the dovetail structure 331 will not abut against the groove wall of the dovetail groove 111 when it is just inserted into the dovetail groove 111. At this time, the rectangular protrusion 321 of the first guide part 32 first plays a guiding role in the first direction. In the process of the dovetail structure 331 being gradually inserted into the dovetail groove 111 along the first direction, the dovetail structure 331 gradually abuts against the groove wall of the dovetail groove 111. At this time, the dovetail structure 331 abuts against the dovetail groove 111 to achieve the limitation in the second direction and the third direction, and at the same time, the locking force between the plug body 3 and the base 1 is improved. After the dovetail structure 331 is tightly abutted against the dovetail groove 111, the plug body 3 is locked without gap, and the installation stability is further improved.

[0046] In other embodiments, the second guide portion 33 may include a first structure and a second structure disposed on both sides of the plug body 3, the first structure and / or the second structure is a dovetail structure 331, the distance between the first structure and the second structure decreases along the first direction to form a trapezoidal structure or a V-shaped structure, and the first guide portion 32 is the trapezoidal structure or the V-shaped structure formed by the first structure and the second structure. It can be understood that the rectangular protrusion 321 is eliminated in this embodiment, and the trapezoidal structure or the V-shaped structure is used as the first guide portion 32 to achieve guidance in the first direction; the dovetail structure 331 achieves limitation in the second direction and the third direction. Preferably, the first structure and the second structure are both dovetail structures 331.

[0047] In one embodiment, please refer to Figure 3 and Figure 4 The locking member 2 includes a limiting portion 21 located on the first guide portion 32, and a moving portion 22 located on the base 1. The moving portion 22 is used to switch between a position close to the limiting portion 21 and a position away from the limiting portion 21 after the first guide portion 32 and the second guide portion 33 complete the guidance, that is, after the plug body 3 is installed on the base 1, so as to lock the plug body 3 to the base 1 by abutting against the limiting portion 21 when switching to the position close to the limiting portion 21.

[0048] For example, please refer to Figures 3 to 5 The limiting portion 21 may include a barb structure 211 located on the first guide portion 32. A slide groove 12 connected to the guide slot 11 may be provided on one side of the base 1. One end of the movable portion 22 passes through the slide groove 12 toward the plug body 3. The other end of the movable portion 22 is used for the user to operate to control the movement of the movable portion 22. The movable portion 22 can move along the preset direction of the slide groove 12. A hollow portion 322 is provided on the first guide portion 32 for the movable portion 22 to pass through when moving. The movable portion 22 moves under the guidance of the slide groove 12, and one end thereof passing through the slide groove 12 switches between a position close to the barb structure 211 and a position away from the barb structure 211. When the movable portion 22 switches to a position close to the barb structure 211, it blocks the side of the notch of the barb structure 211 toward the guide slot 11. When the plug body 3 is to be separated from the base 1, the barb structure 211 will abut against the movable portion 22, thereby achieving limiting, that is, achieving locking of the plug body 3. On the contrary, when the moving portion 22 is switched to a position away from the barb structure 211 , the locking is released, and the plug body 3 can be separated from the base 1 .

[0049] Further, refer to Figure 3 and Figure 4, an elastic member 13 may also be provided in the base 1. Taking the embodiment in which the limiting portion 21 includes a barb structure 211 as an example, specifically, the moving portion 22 is connected to the elastic member 13, and one side of the barb structure 211 is used to push the moving portion 22 to move away from the barb structure 211 and the elastic member 13 during the process of inserting the plug body 3 into the base 1. After the plug body 3 is installed on the base 1, one side of the barb structure 211 is separated from the moving portion 22, and the moving portion 22 is reset to a position close to the barb structure 211 under the influence of the elastic restoring force of the elastic member 13, thereby automatically locking the plug body 3. Exemplarily, the elastic member 13 may be a spring. It can be understood that by providing the elastic member 13, when installing the plug body 3 on the base 1, there is no need to manually switch the position of the moving portion 22, and the installation of the plug body 3 is more convenient and quick.

[0050] For example, please refer again to Figure 3 and Figure 4 The side of the barb structure 211 used to push the locking piece 2 is defined as a pushing portion 2111. The pushing portion 2111 is based on the direction from the bottom of the guide slot 11 to the slot opening, and is obliquely offset in the direction away from the elastic piece 13, so that during the process of the plug body 3 being inserted into the base 1, the pushing portion 2111 can gradually push the locking piece 2 to move in the direction away from the barb structure 211 and the elastic piece 13.

[0051] In one embodiment, please refer to Figure 5 , the base 1 is a power supply base, and the plug body 3 is provided with an electrical connection terminal 31, which is used to electrically connect to the power supply base at least when the plug body 3 is locked to the power supply base. A wire groove 34 is provided on the plug body 3, and a cable (not shown in the figure) is provided in the wire groove 34, one end of the cable is electrically connected to the electrical connection terminal 31, and the other end of the cable is used to electrically connect to an external device. It can be understood that the electrical connection terminal 31 is used to electrically connect to the base 1 at least when the plug body 3 is locked to the base 1, so that the plug body 3 receives power from the base 1 and can transmit electrical energy to the external device through the cable. Preferably, when the plug body 3 is installed on the power supply base (in a locked state or in an unlocked state), the electrical connection terminal 31 is electrically connected to the power supply base. In addition, optionally, the wire groove 34 can be opened in the middle of the plug body 3, or it can be opened on one side of the plug body 3. The arrangement of the electrical connection terminal 31, the wire groove 34 and the cable facilitates the plug body 3 to supply power to external devices, and the arrangement of the wire groove 34 can guide the cables therein, making the direction of the cables clear and the device more concise and beautiful.

[0052] In actual application, please refer to Figure 5, the electrical connection end 31 may include a power supply socket 4 disposed at the lower part of the plug body 3. Specifically, a fixing groove 35 may be provided at the lower part of the plug body 3, and the power supply socket 4 is snapped into the fixing groove 35, and the power supply socket 4 is electrically connected to the cable. A power supply plug 5 is disposed in the power supply base. When the plug body 3 is installed on the power supply base, the power supply socket 4 is electrically connected to the power supply plug 5. In other cases, the power supply socket 4 may also be disposed in the power supply base, and the electrical connection end 31 may include a power supply plug 5 disposed at the lower part of the plug body 3.

[0053] In a specific embodiment, please refer to Figure 1 A locking member pressing plate 14 is also provided on the base 1. Specifically, the locking member pressing plate 14 is used to block the locking member 2 and limit the movement of the locking member 2 in the second direction, thereby preventing the locking member 2 from falling off the base 1, improving the stability of the locking member 2 and prolonging the service life of the device.

[0054] Example 2

[0055] This embodiment provides a lamp, comprising a lamp body 6 and a locking device capable of quick installation and quick locking as described in any of the above embodiments.

[0056] Please refer to Figure 6 For example, when the base 1 is a power supply base, the lamp body 6 is connected to the plug body 3, so that it can be fixed to or removed from the power supply base along with the plug body 3. The fixing direction of the lamp body 6 can be as follows: Figure 6 In the vertical direction shown. In addition, the lamp body 6 is electrically connected to the electrical connection end 31 of the plug body 3 through a cable, so that when the plug body 3 is installed on the power supply base, the plug body 3 receives power from the power supply base. The power supply base can obtain power by electrically connecting to an external power source. It can be understood that the lamp body 6 can achieve the effect of fast fixing and fast power connection by connecting the plug body 3, and has a good user experience.

[0057] When the base 1 is not a power supply base, the lamp body 6 can still be quickly fixed by connecting to the plug body 3, but the lamp body 6 needs to be connected to an external power source to obtain power, or be powered by its own power storage module.
