[0036] Please refer to Figure 1 and Figure 4The lifting mechanism 100 and the lamp 1000 provided in the embodiment of the utility model can solve the above-mentioned problem, which will be described in detail below.

[0037] refer to Figure 1-Figure 3 , the lifting mechanism 100 for a lamp comprises a first lamp pole 110, a second lamp pole 120 and a transmission member 130;

[0038] Among them, the transmission member 130 includes a transmission wheel 131, a transmission handle 132 and a transmission bar 133, the transmission bar 133 is arranged on the first lamp pole 110, the transmission wheel 131 and the transmission handle 132 are arranged on the second lamp pole 120, the transmission handle 132 is connected to the transmission wheel 131, the transmission wheel 131 and the transmission bar 133 are coordinated for transmission, and the transmission handle 132 is used to drive the transmission wheel 131 to rotate under the action of external force, so that the transmission bar 133 moves relative to the transmission wheel 131, and the first lamp pole 110 is lifted and lowered relative to the second lamp pole 120.

[0039] During use, external force can be applied through the handle to make the transmission wheel 131 and the transmission bar 133 cooperate with each other, and the rotational movement of the transmission wheel 131 is converted into axial movement of the transmission bar 133, thereby driving the first lamp pole 110 and the second lamp pole 120 to be raised and lowered, so that the height of the lamp 1000 is adjusted, thereby improving the versatility of use of the lamp 1000.

[0040] It should be noted that one of the first lamp pole 110 and the second lamp pole 120 can be fixed, while the other can be movable, and then through the transmission effect, the two can move relative to each other, which can be specifically closer to each other or farther away from each other, thereby making the length of the overall lamp pole longer or shorter, so as to drive the height of the lamp 1000 to be adjusted.

[0041] refer to Figure 3 The transmission wheel 131 is a gear, the transmission bar 133 is a rack, the gear and the rack are meshed, and the gear and rack transmission has the advantages of high transmission accuracy, long service life, stable transmission and compact structure.

[0042] Of course, the transmission wheel 131 can also be a friction wheel, and the transmission bar 133 can be a friction belt. The friction wheel and the friction belt can be coordinated, that is, the friction wheel and the friction belt can be regarded as a belt drive, which has the advantages of smooth transmission, low wear, low noise, simple structure, and easy buffering and vibration absorption.

[0043] refer to Figure 1 and Figure 2 In order to make the structure simpler and more compact while adjusting the lifting and lowering, one end of the second lamp pole 120 can be opened and formed with a lifting cavity 121, and the first lamp pole 110 and the transmission bar 133 can be movably accommodated in the lifting cavity 121.

[0044] When it is necessary to raise the lamp, the second lamp pole 120 can be raised from the lifting chamber 121 through transmission cooperation to extend the length of the entire lamp pole; when it is necessary to lower the lamp, the second lamp pole 120 can be put into the lifting chamber 121 through transmission cooperation to reduce the length of the entire lamp pole. At the same time, the lifting chamber 121 can store and protect the second lamp pole 120, so that the overall volume of the lamp 1000 is reduced, which is convenient for storage and transportation.

[0045] refer to Figure 1-Figure 3 The transmission member 130 also includes a transmission shell 134, which is connected to the second lamp pole 120. The transmission shell 134 is sleeved on the transmission wheel 131. The transmission handle 132 passes through the transmission shell 134. The side wall of the second lamp pole 120 is provided with an adjustment hole 122, which is connected between the lifting cavity 121 and the inner cavity of the transmission shell 134.

[0046] In the above technical solution, by providing the transmission shell 134, the transmission wheel 131 can be protected, so as to avoid the transmission wheel 131 being directly exposed and to prevent dust and impurities from adhering to the transmission wheel 131 and affecting the transmission effect.

[0047] In this embodiment, the transmission housing 134 can be detachably connected to the second lamp pole 120 by bolts, thereby facilitating the maintenance and replacement of the transmission wheel 131; of course, in other embodiments of the present invention, the transmission housing 134 can also be detachably connected to the second lamp pole 120 by a snap-on structure, and the specific connection method between the transmission housing 134 and the second lamp pole 120 is not limited.

[0048] refer to Figure 1 and Figure 3 The transmission handle 132 is Z-shaped and includes a first section 1321, a second section 1322 and a third section 1323 which are connected in sequence. The first section 1321 is connected to the transmission wheel 131, and the third section 1323 is used to rotate around the first section 1321 as a circle center under the action of an external force.

[0049] In this embodiment, the first section 1321 and the third section 1323 are parallel, and the second section 1322 is perpendicular to both the first section 1321 and the third section 1323, so that when the operator rotates the third section 1323, there will be no interference with the second lamp pole 120 next to it, thereby facilitating force application and rotation.

[0050] refer to Figure 3 The lifting mechanism 100 for the lamp also includes a locking member 140, which includes a locking wheel 141 and a locking bar 142. The locking wheel 141 is connected to the transmission wheel 131, and the locking bar 142 is connected to the transmission bar 133. The locking wheel 141 is used to resist or disengage from the locking bar 142 to lock or unlock the transmission wheel 131 and the transmission bar 133.

[0051] Specifically, a locking protrusion 1411 is formed on the locking wheel 141 , and a plurality of locking grooves 1421 are formed on the locking strip 142 . The locking wheel 141 is used to rotate under the action of an external force so that the locking protrusion 1411 abuts against or disengages from the locking groove 1421 .

[0052] When the relative height of the first lamp pole 110 and the second lamp pole 120 is adjusted to the desired position, the locking wheel 141 can be rotated to make the locking protrusion 1411 abut against the locking groove 1421 to achieve locking and fixing, thereby preventing the transmission wheel 131 and the transmission bar 133 from transmitting relative to each other under the influence of gravity or other external forces. When further adjustment or unlocking is required, the locking wheel 141 can be rotated in the opposite direction to make the locking protrusion 1411 disengage from the locking groove 1421.

[0053] refer to Figure 3 In order to improve the convenience of the user applying force to rotate the locking wheel 141, the locking member 140 may further include a locking handle 145, which is connected to the locking wheel 141 and is used to drive the locking wheel 141 to rotate under the action of an external force.

[0054] Furthermore, the locking handle 145 may be connected to the edge of the locking wheel 141 or to the center of the locking wheel 141 , and the specific connection position is not limited.

[0055] refer to Figure 1-Figure 3 The transmission housing 134 can also be sleeved on the transmission wheel 131 and the locking wheel 141 at the same time. The transmission housing 134 is provided with a limiting hole 135 extending in an arc shape, and the locking handle 145 is accommodated in the limiting hole 135.

[0056] In the above technical solution, a limiting hole 135 is provided to limit the movable stroke of the locking handle 145, thereby preventing the locking handle 145 from moving too far and preventing the locking protrusion 1411 on the locking wheel 141 from reversely abutting against the locking groove 1421 to cause locking damage.

[0057] refer to Figure 4 The embodiment of the utility model further provides a lamp 1000, including a lamp holder 200, a support seat 300 and a lifting mechanism 100 for the lamp, wherein the lamp holder 200 and the support seat 300 are respectively connected to ends of the first lamp pole 110 and the second lamp pole 120 that are away from each other.

[0058] The lamp 1000 can be raised and lowered by the first lamp pole 110 and the second lamp pole 120, so that the relative distance between the lamp head 200 and the support seat 300 changes, and the height of the lamp 1000 is adjusted, thereby improving the versatility of the lamp 1000.

[0059] In summary, the lifting mechanism 100 for a lamp and the lamp 1000 provided by the embodiment of the utility model have at least the following advantages:

[0060] (1) External force can be applied through the transmission handle 132 to make the transmission wheel 131 and the transmission bar 133 cooperate with each other, and the rotational movement of the transmission wheel 131 is converted into the axial movement of the transmission bar 133, thereby driving the first lamp pole 110 and the second lamp pole 120 to move up and down, so that the height of the lamp 1000 can be adjusted, thereby improving the versatility of the lamp 1000.

[0061] (2) The locking wheel 141 can be rotated so that the locking protrusion 1411 abuts against the locking groove 1421 to achieve locking and fixation, thereby preventing the transmission wheel 131 and the transmission bar 133 from transmitting relative to each other under the influence of gravity or other external forces.

[0062] (3) The limiting hole 135 can be provided to limit the movable stroke of the locking handle 145, thereby preventing the locking handle 145 from moving too far and preventing the locking protrusion 1411 on the locking wheel 141 from abutting against the locking groove 1421 in the reverse direction to cause locking damage.

[0063] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
