Compact type lifting device

Abstract

The invention discloses a compact type lifting device. The compact type lifting device comprises a box body, a rolling executing mechanism and a rolling assisting mechanism, wherein the rolling executing mechanism is arranged inside the box body; the rolling assisting mechanism is matched with the rolling executing mechanism and is used for assisting the rolling of a wire; the box body is providedwith a wire inlet and a wire outlet; the rolling executing mechanism comprises a rolling roller and a rotation driving mechanism which is used for driving the rolling roller to rotate to implement rolling and unrolling; the rolling assisting mechanism is arranged at one side of the rolling roller and comprises a mobile frame and a movement driving mechanism, wherein the mobile frame is used for limiting the position, in the axis direction of the rolling roller, of a wire which is being rolled; the movement driving mechanism is used for driving the mobile frame to move in the axis direction ofthe rolling roller; the mobile frame is provided with a positioning part used for positioning the wire; and the wire is rolled on the rolling roller after bypassing the positioning part. The compacttype lifting device has the advantages of being capable of rolling a long wire and small in size.

Description

technical field [0001] The invention relates to a kinetic energy lamp, in particular to a kinetic energy lamp lifting device. Background technique [0002] In order to obtain specific lighting effects, some kinetic energy lamps used in the prior art have a lifting function, and the kinetic energy lamps can perform lifting movements during use. Specifically, one end of the kinetic energy lamp is connected to a wire, and the wire not only plays a role in suspending the kinetic energy lamp, but also plays a role in energizing the kinetic energy lamp; during work, when the kinetic energy lamp needs to perform lifting tasks, by controlling the kinetic energy lamp lifting device Elevate the task after coming. [0003] The existing kinetic energy lamp lifting device is mainly composed of an outer box, a winding mechanism, a winding power mechanism, etc., and the winding mechanism and the winding power mechanism are arranged in the outer box. [0004] For example, the utility mode...

[0005] Refer to the description of the above-mentioned patent documents and in the accompanying drawings of the description image 3 It can be seen that when the winding shaft is wound, the wires are arranged outward layer by layer along the radial direction from the winding shaft. , can only be arranged in one layer along the axial direction of the rewinding shaft), the following problems will be caused during use: 1. When the wire to be rewound is long, the rewinding space needs to be increased, that is, the box needs to be increased. However, in actual application, since the kine
