Problems solved by technology
This patent protects a lifting fan whose inner diameter of the upper tube is larger than the outer diameter of the lower tube. However, the fixation of the upper and lower tubes after stretching is still the traditional way: a number of positioning holes are set in the upper tube, and inserted through the fixed insertion rod. In the positioning hole, in order to realize the fixing after stretching in the vertical direction, this fixing method requires manual operation, which is relatively cumbersome, and requires high installation accuracy between the positioning hole and the fixed insertion rod

Embodiment Construction
[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0035] like Figure 1-4 As shown, the lifting device in the present invention includes: a fixed lower tube body 2 , and an upper tube body 4 slidably arranged in the lower tube body 2 and at least partially protruding upward from the lower tube body 2 .
[0036] The lifting device of the present invention also includes a locking groove 6, a lifting locking block 8 and a locking control mechanism 10, wherein:
[0037] The locking grooves 6 are arranged on the arc-shaped contour surface of the upper pipe body 4, there are at least two of them, and they are spaced apart in the vertical direction;
[0038] The lifting locking block 8 can be snapped inwardly into the locking groove 6 at the same horizontal position;
[0039] The locking control mechanism 10 can push the lifting locking block 8 and the ...

The invention discloses a lifting device and a fan using the same. The lifting device comprises a lower pipe body which is fixedly arranged and an upper pipe body connected to the lower pipe body in a sliding manner, and is characterized by comprising locking grooves, a lifting locking block and a locking control mechanism, wherein the locking grooves are formed in the cambered contour surface of the upper pipe body; the lifting locking block can be clamped into the locking groove positioned on the same horizontal plane; the locking control mechanism can be used for driving the lifting locking block to be separated from the locking groove when external force is loaded, and providing elasticity for clamping the locking block into the locking groove positioned on the same horizontal plane when the external force is unloaded. According to the lifting device and the fan using the same, the locking control mechanism is arranged to automatically clamp the lifting locking block into one locking groove when the locking groove moves to the same horizontal plane with the lifting locking block along with the upper pipe body, so that the problem of the prior art is solved.
Description
technical field [0001] The invention relates to a lifting device for a fan and a fan using the lifting device, belonging to the field of household appliances. Background technique [0002] At present, most liftable electric fans on the market are adjusted in height through lift tubes. The lift tube includes an upper tube and a lower tube nested with each other, wherein one end of the upper tube is connected with the fuselage, and the other end is set with the lower tube, and the purpose of lifting adjustment is achieved by the expansion and contraction of the upper tube in the lower tube. [0003] Chinese patent (CN103244386A) discloses a liftable electric fan, including a fuselage and a lift tube, the lift tube includes an upper tube and a lower tube, the upper tube is fixedly installed inside the fuselage, and the upper tube The inner diameter of the lower tube is larger than the outer diameter of the lower tube, one end of the lower tube is sleeved in the upper tube, and...
