Background technique

The most important step in the construction industry is to measure the size and make a plan. As a basic measuring instrument in the home, the surveying and mapping industry has been popularized, and it has been widely recognized by people for its good storage capacity and convenient use. People who often use tape measures in their work generally have a greater labor intensity than other industries, especially those who work outdoors in summer. The hot climate will bring people a strong sense of discomfort, and in a modern society where energy is scarce, Energy depletion and environmental pollution are the biggest problems people face. As electricity enters human society as a clean energy source, it largely replaces fuel-powered engines. The difficulty in setting up power in mountainous areas has become another problem.

Ordinary tape measure, the model generally only has the surveying and mapping function, which is also the basic function of the ruler, but the retracting and stretching of the ruler during use, and the curling work of the coil spring are all energy sources. The mechanical energy generated cannot be ignored. The accommodation conditions on the general construction site are not good, and power outages occasionally occur in remote areas. Therefore, a tape measure that can recover energy and realize the functions required by the site situation is of great significance. of.

Utility model content

In order to solve the above problems, the utility model provides a multifunctional measuring tape, which has a simple and reasonable structure, can effectively recover electricity, and also has a power storage function to realize blowing and lighting, which is very practical in daily life.

In order to achieve the above object, the technical solution adopted by the utility model is: a novel multifunctional tape measure, including a USB interface, a fan, a generator, a wire, an LED light and a storage battery, and also includes a shell, a middle shell ventilating shell and an energy storage device , the shell is provided with a cylindrical cavity, a scroll spring ruler is installed in the cylindrical cavity, and the upper layer of the scroll spring ruler has teeth. Correspondingly, the energy storage device There are double gears, and the outer casing is also provided with LED lights and several function knobs. The middle casing is covered on the scroll spring ruler and connected with the outer casing. The middle casing is also fixed with a fan. The ventilated shell is fixed on the middle shell, the function knob, LED light and fan are all connected to the energy storage device through wires, and the LED light and fan are connected to the function knob through wires.

Preferably, the energy storage device is composed of a duplex gear, a face gear, a generator, and a storage battery, the duplex gear meshes with the face gear, and the face gear is sleeved on the transmission shaft of the motor, so The motor described above is connected to the storage battery through wires.

As a preference, the middle shell is connected to the outer shell through a hexagonal copper column, and the ventilated shell is fixed on the hexagonal copper column through countersunk screws

The utility model can cleverly convert the mechanical energy released by the coil spring into kinetic energy, and then drive the generator to generate electricity through the gear transmission mechanism, and store the collected electricity in the battery, which can be used by fans or LED lights, and has a compact structure and a simple mechanism. , to ensure durability and service life, it is very practical for workers who often work in the field.

Detailed ways

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1-3, this embodiment provides a new type of multifunctional tape measure, including a USB interface, a fan 6, a generator 4, wires, an LED light 1 and a battery 8, and also includes a shell, a middle shell 5, and a ventilated shell 6 and the energy storage device, a function knob 2 is fixed on the shell 3, an LED light 3 is installed on the inclined surface of the shell 3, the LED light is an integral circuit, a fixed column is arranged in the middle of the shell 3, a scroll spring ruler 9 vortex One end of the coil spring is fixed on the fixed column and the other end is connected with the steel ruler. The other end of the steel ruler protrudes from the window constructed on the casing 3. Teeth 11 are constructed on the upper half of the steel ruler, and the casing has a strip. There is a certain distance between the strip and the shell wall so as to form a groove. The corresponding groove just accommodates the lower half of the steel ruler. The scroll reed 9 is coaxially fixed on the fixed column constructed on the bottom of the shell 3. The shape groove just accommodates the double gear 10, and its shape and position relationship limits the engagement of the large gear plate of the double gear with the teeth on the steel ruler. 4, the generator 4 is fixed on the bottom surface of the shell 3, the generator 4 is connected to the rectifier 13 through wires, the rectifier 13 is connected to the battery 8, the middle shell 8 is covered on the scroll spring ruler 9 and screwed into the hexagonal copper column through the pillar Fixed, the middle shell is divided into upper and lower layers in a stepped shape, the lower layer is circular, the upper layer is rectangular, the rectifier and battery 8 are fixed on the upper layer of the middle shell 5, the fan 6 is fixed on the lower layer of the middle shell 5, LED lights 2, fans 6 and The battery 8 is connected to the function knob 2 through wires, the fan 6 and the LED lamp 2 are connected to the battery 8 through wires, the ventilated casing 7 is installed on the hexagonal copper column of the middle casing 5 through countersunk screws and fastened to the casing 3, and the casing has a Charging port, use the USB port, and connect the rectifier 13.

Wherein, the face gear 12 is connected with the drive shaft of the motor through a key.

Wherein, scroll gear 9 is made up of the fixed rigid rule of the end of scroll spring.
