Problems solved by technology

[0002] There are few types of existing electric external flagpole lifters, some of which cannot control the lifting time, and cannot be synchronized with the length of the music. Even if the purpose of synchronous lifting is achieved, its structure is relatively complicated, and the failure rate is high. Inconvenient, and the production cost is high, it is not suitable for the needs of the modern market. It needs further improvement in the field of automatic control of the lifting flag. It is urgent to introduce a 220-volt voltage control, which can also be controlled by batteries. In the case of power failure, without affecting the lifting speed, it can be converted into battery-driven lifting immediately, so as to meet the needs of the modern market

Embodiment Construction

[0024] Such as figure 1 As shown, the bracket plate 1 is fixed on the middle part of the base 2 with the fixing screw rod B24 and the fixing nut C25. Such as figure 2 , image 3 As shown, a fixed frame 4, a clutch frame 6 and two cover lock slots 8 are also welded on the top of the base 2. combine figure 1 , figure 2 , image 3 , Figure 11 As shown, a gear transmission structure is provided inside the gear cover 10. The gear transmission structure is fixedly meshed with the center shaft gear 51 in the middle of the bracket plate 1 and the limit gear 50 and is clutched with the motor gear 53. The center shaft gear 51 is installed on the central shaft, and the central shaft is welded with the support plate 1. Such as Figure 4 , Figure 5 As shown, the central shaft gear 51 is provided with a fixed screw rod C30, and the middle part of the disc 28 is provided with a hole passing through the fixed screw rod C30, and the disc 28 is locked with a fixed nut D29. The fix...

Abstract

An external flag staff lifter includes a fixed support disposed on the upper part of a base, a clutch bracket, a housing lock groove and a support plate at the middle of the base, wherein, a lifting line wound onto a main wheel is connected with the upper end and the lower end of the flag staff after passing through a line pressing wheel A, the groove of a line pressing wheel and the line pressing wheel groove at the upper part of the flag staff. A gear drive mechanism is arranged in a gear cover on one side of the support plate and is fixedly engaged with a limit gear and is clutch engaged with a motor gear via a central shaft gear mounted onto a central shaft. The central shaft is welded or fixed with the support plate in the other manners; limiter, a main motor, a speed reducer and a clutch of the speed reducer are arranged on the other side of the support plate. The lifter of the invention is installed outside the flag staff, the lifting time is synchronous with the length of music, the lifting process can be controlled by 220V voltage or by battery, thereby, during in the lifting process, when the power is cut off, the lifting can be driven by battery without influencing the lifting speed.

Description

technical field [0001] The invention relates to a lifting controller capable of raising and lowering flags, in particular to an external flagpole lifter arranged outside a flagpole and capable of raising and lowering flags synchronously with music. Background technique [0002] There are few types of existing electric external flagpole lifters, some of which cannot control the lifting time, and cannot be synchronized with the length of the music. Even if the purpose of synchronous lifting is achieved, its structure is relatively complicated, and the failure rate is high. Inconvenient, and the production cost is high, it is not suitable for the needs of the modern market. It needs further improvement in the field of automatic control of the lifting flag. It is urgent to introduce a 220-volt voltage control, which can also be controlled by batteries. In the case of power failure, without affecting the lifting speed, it can be converted to battery-driven lifting immediately, so...
