DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the accompanying Figs. 1-3 The present application will be further described in detail.

[0026] The embodiment of the present application discloses a birdcage lamp. Referring to Figs. 1-3 , the birdcage lamp comprises a first cover body 1, a second cover body 2 and a connecting piece 3, the first cover body 1 is detachably connected with the connecting piece 3, the second cover body 2 is detachably connected with the connecting piece 3, that is, the first cover body 1 is detachably connected with the second cover body 2 through the connecting piece 3. Among them, the first cover body 1 is located above the second cover body 2, and the connecting piece 3 is located between the first cover body 1 and the second cover body 2.

[0027] Specifically, the first cover body 1 has a first internal thread 11, the connecting piece 3 has a first external thread 31, the first internal thread 11 and the first external thread 31 are threadedly matched, and the detachable connection of the first cover body 1 and the connecting piece 3 is realized.

[0028] The second cover body 2 has a second internal thread 21, the connecting piece 3 has a second external thread 32, the second internal thread 21 and the second external thread 32 are threadedly matched, and the detachable connection of the second cover body 2 and the connecting piece 3 is realized.

[0029] The first cover body 1 is internally provided with a first sliding rod 4, and the second cover body 2 is internally provided with a second sliding rod 5. The first sliding rod 4 is slidably connected to the second sliding rod 5 along the length direction of the second sliding rod 5, and the first sliding rod 4 cannot rotate relative to the second sliding rod 5. Thus, by means of the cooperation of the first sliding rod 4 and the second sliding rod 5, when the connecting piece 3 is screwed, the second cover body 2 can translate relative to the first cover body 1 but cannot rotate. The connection mode between the first sliding rod 4 and the first cover body 1 includes but is not limited to adhesion, welding, clamping and the like. The connection mode between the second sliding rod 5 and the second cover body 2 includes but is not limited to adhesion, welding, clamping and the like.

[0030] When the connecting piece 3 is screwed relative to the first cover body 1 in the forward direction, the first cover body 1 and the second cover body 2 move away from each other. When the connecting piece 3 is screwed relative to the first cover body 1 in the reverse direction, the first cover body 1 and the second cover body 2 move close to each other.

[0031] Specifically, the first sliding rod 4 is provided with a plug-in groove 41 extending along the length direction of the first sliding rod 4, and the plug-in groove 41 is used for plug-in of the second sliding rod 5. In the embodiment, the plug-in groove 41 is coaxially arranged with the first sliding rod 4, and the plug-in groove 41 is a square groove. In other embodiments, the plug-in groove 41 can also be other polygonal grooves.

[0032] The outer wall of the second sliding rod 5 is provided with an anti-skid part used for abutting with the groove wall of the plug-in groove 41 to increase the damping when the second sliding rod 5 moves relative to the first sliding rod 4, temporarily fix the second cover body 2, prevent the second cover body 2 from having too large falling force under the action of its own gravity, and improve the convenience of operation.

[0033] In the embodiment, the anti-skid part is an anti-skid paint coated on the outer wall of the second sliding rod 5.

[0034] When the lengths of the first sliding rod 4 and the second sliding rod 5 are set, the first sliding rod 4 still needs to be connected to the second sliding rod 5 when the first cover body 1 and the connecting piece 3 are separated and the second cover body 2 and the connecting piece 3 are separated, so that the first cover body 1, the connecting piece 3 and the second cover body 2 will not be suddenly separated, and the risk of lamp damage is reduced.

[0035] Further, the end of the first sliding rod 4 away from the first cover body 1 is provided with a first magnet 42, the end of the second sliding rod 5 away from the second cover body 2 is provided with a second magnet 51, and the first magnet 42 and the second magnet 51 attract each other. Thus, when the first sliding rod 4 and the second sliding rod 5 relatively move to the end, the connection stability between the first sliding rod 4 and the second sliding rod 5 is strengthened by means of the cooperation of the first magnet 42 and the second magnet 51, and the risk of lamp damage is further reduced.

[0036] In the embodiment, the first slide rod 4 is provided with a plurality of first slide rods 4 which are arranged at intervals around the central axis of the first cover body 1. The second slide rod 5 is correspondingly provided with a plurality of second slide rods 5 which are arranged at intervals around the central axis of the second cover body 2, so as to improve the stability of the movement of the first cover body 1 relative to the second cover body 2.

[0037] The implementation principle of the birdcage lamp according to the embodiment of the application is as follows: when the bulb of the birdcage lamp is replaced, the connecting piece 3 is first screwed in the positive direction relative to the first cover body 1, so that the first cover body 1 and the second cover body 2 gradually move away from each other and are separated from the connecting piece 3. During the screwing process, the first slide rod 4 slides along the length direction of the second slide rod 5 relative to the second slide rod 5. When the first cover body 1 and the connecting piece 3 are separated and the second cover body 2 and the connecting piece 3 are separated, the end portion of the second slide rod 5 reaches the end portion position of the first slide rod 4. Under the action of the friction force between the first slide rod 4 and the second slide rod 5 and the attraction force between the first magnet 42 and the second magnet 51, the first slide rod 4 and the second slide rod 5 are still connected. At this time, a downward force is applied to the second cover body 2, so that the second cover body 2 and the second cover body 2 are completely separated, and the connecting piece 3 is removed, and the bulb can be replaced. After the replacement is completed, the above operation is performed in the reverse direction, and the first cover body 1, the connecting piece 3 and the second cover body 2 are connected again.

[0038] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
