[0033] The limiting mechanism 2 is arranged inside the fixing mechanism 1 and is used to limit the installation of the bulb body 3 .

[0034] In order to conveniently install and fix the bulb body 3, Figure 2 and Figure 3 As shown, the fixing mechanism 1 includes a fixing seat 101, a placement groove 102 is opened on the top of the fixing seat 101, the inner wall of the placement groove 102 is movably connected to the outer wall of the bottom of the bulb body 3, and the placement groove 102 can place the bulb body 3 so that the bulb body 3 is stably connected to the circuit.

[0035] In order to ensure that the bulb body 3 can be stably fixed inside the fixing mechanism 1, as shown in FIG. Figure 2 and Figure 4 As shown, the limiting mechanism 2 includes a support plate 201 and two traction springs 206. The support plate 201 is arranged at the inner bottom of the placement groove 102. The traction plates 202 are rotatably installed on both sides of the bottom of the support plate 201. The bottoms of the two traction plates 202 are rotatably installed with movable seats 203. A connecting spring 204 is fixedly installed between the two movable seats 203. The two traction springs 206 are respectively arranged on the inner walls of the tops of the two ends of the placement groove 102. The opposite ends of the two traction springs 206 are fixedly installed with limiting plates 207. A protective plate 208 is fixedly installed on the top of the limiting plates 207. Fastening bolts 209 are arranged between the opposite ends of the two limiting plates 207 and the inner wall of the fixed seat 101. The support plate 201 can place and connect the lamp holder 301 of the bulb body 3. The limiting plate 207 can suppress and limit the bayonet 302 under the elastic force of the traction spring 206, so that the bulb body 3 can be stably fixed to the placement groove 102.

[0036] In order to conveniently install and fix the bulb body 3, Figure 2 and Figure 5As shown, the bulb body 3 includes a lamp holder 301, and a latch 302 is fixedly installed at the bottom of the outer walls at both ends of the lamp holder 301. A lampshade 303 is fixedly installed on the top of the lamp holder 301. The outer wall of the lamp holder 301 is movably connected to the inner wall of the placement groove 102. The connection between the lamp holder 301 and the placement groove 102 allows the bulb body 3 to be fixed to the inside of the fixing mechanism 1.

[0037] In order to keep the latch 302 stable inside the receiving slot 104, Figure 2-5 As shown, the top of the inner wall at both ends of the placement groove 102 is provided with a receiving groove 104, the inner wall of the receiving groove 104 is movably connected with the adjacent bayonet 302, the bayonet 302 is arranged at the bottom of the adjacent limiting plate 207, the inner wall of the two receiving grooves 104 at the opposite end is provided with a fixing groove 105, the inner wall of one end of the two fixing grooves 105 is respectively fixedly connected with the end of the two traction springs 206 away from the limiting plate 207, the inner wall of one end of the fixing groove 105 is threadedly connected with the fastening bolt 209, and the fastening bolt 209 is fastened. The end 9 away from the inner wall of the fixing groove 105 is in contact with the outer wall of the adjacent limiting plate 207, and the fastening bolt 209 is movably inserted into the inner side of the adjacent traction spring 206. The receiving groove 104 can limit the movement of the limiting plate 207, so that the limiting plate 207 can suppress and limit the latch 302 under the elastic force of the traction spring 206. The fastening bolt 209 penetrates the inner wall of the fixing groove 105 and is in contact with the adjacent limiting plate 207, so that the bulb body 3 is stably connected to the fixing mechanism 1.

[0038] In order to make the support plate 201 able to stably support the lamp holder 301, Figure 2-4 As shown, a movable groove 103 is opened on the bottom inner wall of the placement groove 102, and the two ends of the inner wall of the movable groove 103 are movably connected to the outer walls of the two movable seats 203 respectively. A limiting rod 205 is fixedly installed on the bottom of the inner wall of the movable groove 103, and the limiting rod 205 is movably inserted into the inner side of the connecting spring 204. The outer walls at both ends of the limiting rod 205 are movably connected to the inner walls of the two movable seats 203 respectively. The movable groove 103 and the limiting rod 205 can limit the movement of the two movable seats 203, so that the movable seats 203 remain stable during the movement, so that the support plate 201 can stably support the lamp holder 301.

[0039] In order to prevent the portion of the lamp holder 301 located outside the placement groove 102 from being worn, Figure 2 and 4 -5, the protective plate 208 is arranged as a fan-shaped structure in cross section when viewed from above, and the inner side of the protective plate 208 is movably connected to the outer wall of the top of the lamp holder 301 near the lampshade 303. The protective plate 208 can protect the portion of the lamp holder 301 located outside the placement groove 102 to avoid rust damage.

[0040] The specific implementation method is as follows: when installing and using the bulb body 3, the lamp holder 301 is inserted into the placement groove 102, so that the two latches 302 can move downward along the inner wall of the adjacent storage groove 104. As the lamp holder 301 moves, pressure is generated on the support plate 201, so that the support plate 201 moves downward along the inner wall of the placement groove 102, so that the two traction plates 202 expand toward both sides, so that the two movable seats 203 can be pushed to move along the inner wall of the movable groove 103 outside the limiting rod 205, so that the connecting spring 204 extends. When the latch 302 contacts the bottom of the inner wall of the storage groove 104, the two limiting plates 207 can be pushed to move relative to each other by rotating the two fastening bolts 209. The movement of the limiting plate 207 causes the traction spring 206 to extend, and with the movement of the limiting plate 207, it can be on top of the two latches 302, so that the latches 302 can be pressed and limited, so that the bottom of the lamp holder 301 can be stably contacted and connected with the support plate 201, and at the same time, the lamp holder 301 can remain stable inside the placement groove 102, and the protective plate 208 can protect the part of the lamp holder 301 located outside the placement groove 102, so that the bulb body 3 can be stably connected with the fixing mechanism 1, and the stable operation of the bulb body 3 can be ensured. This embodiment specifically solves the problem that the LED bulb is prone to wear and looseness during installation in the prior art, which affects the working state of the bulb.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
