Shaft type waterproof window opener structure

Abstract

The utility model provides a shaft type waterproof window opener structure, which relates to the field of window openers and comprises a motor reduction gearbox power output shaft, and waterproof sealing is performed between the position of the motor reduction gearbox power output shaft and the position of a rear-end cable. The front-end waterproof seal is formed by a motor reduction gearbox power output shaft and a motor reduction gearbox shell through an O-shaped rubber sealing ring in a waterproof mode, the rear-end waterproof seal is formed by a cable waterproof connector and a cable in a waterproof mode, and finally effective waterproof sealing is carried out on parts needing waterproof, such as a speed reducer gear box, a motor and a motor control panel. The utility model has the advantages of higher waterproof position precision, good waterproof effect, no change of the volume in the waterproof cavity, no generation of negative pressure, better sealing effect, better operation environment and longer service life, and the waterproof position is in the equipment in the operation process of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of window openers, and in particular to a fire-fighting electric window opener for a natural fire-fighting smoke exhaust window system. Background Technology

[0002] Most window openers currently on the market are not waterproofed; only the circuit boards are waterproofed or potted. A small number of shaft-type window openers have waterproofing on the outer casing, but the waterproofing effect is very poor and cannot meet the requirements of actual use.

[0003] 1. Waterproof gaskets are applied to the outer tube and the protruding shaft. The inner tube is a decorative tube and its precision is insufficient to meet the accuracy requirements.

[0004] 2. During the process of the inner shaft extending, the overall volume of the equipment increases, and negative pressure is generated inside the equipment, making the seal ineffective.

[0005] 3. The product is used in environments near windows, such as airports, train stations, shopping malls, stadiums, convention centers, and industrial plants. These environments are exposed to wind and sun, and dust can accumulate when the windows are open. After repeated use, the sealing ring will wear out and lose its waterproof performance. Summary of the Invention

[0006] The purpose of this invention is to increase the waterproof and moisture-proof performance of window openers, thereby extending their service life during daily use.

[0007] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0008] A shaft-type waterproof window opener structure includes a motor gearbox power output shaft. The position of the motor gearbox power output shaft and the position of the rear cable are waterproofed. The front waterproof seal is achieved by the motor gearbox power output shaft and the motor gearbox housing through an O-ring rubber seal. The rear waterproof seal is achieved by the cable waterproof connector and the cable. Ultimately, the components requiring waterproofing—the gearbox, motor, and motor control board—are effectively waterproofed.

[0009] The beneficial effects of this utility model are: it effectively improves the waterproof and moisture-proof performance of the core components, the motor and the control board, reduces the product failure rate, and improves product quality and product lifespan. Attached Figure Description

[0012] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0013] like Figure 1 As shown, the product application principle is that the motor (6) is driven by electricity, and the motor reduction gearbox (4) reduces the speed and increases the lifting force, so that the lead screw (12) rotates and drives the lead screw nut (11) to move linearly. The force is transmitted by the inner shaft (10). One end is fixed at the window opening position and the other end is fixed at the window fixed position. The motor (6) is controlled to rotate forward or backward by different power supply methods, thereby realizing the extension or shortening of the shaft window opener (1) and thus realizing the window opening and closing function.

[0014] Example 1: The technical solution invented by our company is that the front-end waterproof seal is achieved by the motor gearbox power output shaft (2) and the motor gearbox housing (5) through an O-ring rubber seal (3). The rear-end waterproof seal is achieved by the cable waterproof connector (8) and the cable (9).

[0015] Ultimately, the components requiring waterproofing—the gearbox (4), the motor (6), and the motor control board (7)—will be effectively waterproofed and sealed.

[0016] This patent also applies to the reduction gearbox (4), motor (6), and motor control board (7), which can be separated or combined to achieve waterproofing.

[0017] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.

Claims
