Abstract
The invention discloses an air-pressure balancing device in a lamp holder body, which is used for keeping air pressure in the lamp holder body balance. The air-pressure balancing device comprises the lamp holder body which comprises a top cover, a middle shell and a base, wherein a luminescent device and a power device for providing the energy for the luminescent device are arranged in the middle shell, an elastic air bag is also arranged in the middle shell, and a ventilation hole on the elastic air bag is connected to a ventilation pipe on the base through an air pipe. The air-pressure balancing device in the lamp holder body can ensure that the air pressure in the lamp holder body keeps balanced and prevent the middle shell from swelling and cracking.
Description
Technical field
The present invention relates to the body that is used for traffic lights, relate in particular to the air-pressure balancing device in a kind of body.
Background technology
When the city has a power failure; usually can use portable traffic lights to direct traffic; this traffic lights; be by body; body is made up of top cover, middle casing and base; connecting rod and base constitute, luminescent device is installed in the body and provides the power device of energy to luminescent device, the storage battery operated by rotary motion in base as total energy.In order to prevent the erosion of rainwater, body is made into enclosed construction, but the shortcoming that this enclosed construction exists is: after being subjected to long-time solar light irradiation, temperature in the body is higher, add the heat that power device itself distributes, the middle casing temperature inside can progressively rise, along with the rising of temperature, air pressure in the middle casing also can cause the middle casing swelling cracking easily along with rising.
Summary of the invention
Technical problem to be solved by this invention is: a kind of air-pressure balancing device that can make in the body that air pressure in the body keeps balance is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the air-pressure balancing device in the body, comprise: body, body is made up of top cover, middle casing and base, be provided with luminescent device in the middle casing and the power device of energy is provided to luminescent device, also be provided with elastic bag in described middle casing, the passage on the elastic bag is connected on the breather pipe on the base by tracheae.
In order to solve the problems of the technologies described above better, the further technical scheme of the present invention is: described elastic bag is arranged on the interior heat radiation aluminum pipe of body.
In order to solve the problems of the technologies described above better, the further technical scheme of the present invention is: described body is spherical in shape.
Advantage of the present invention is: the air-pressure balancing device in the body of this structure can make the air pressure in the body keep balance, prevents the middle casing swelling cracking.
Description of drawings
Fig. 1 is the structural representation of the air-pressure balancing device in the body of the present invention.
Among the figure: 1, top cover, 2, middle casing, 21, luminescent device, 22, power device, 23, elastic bag, 24, tracheae, 3, base, 31, breather pipe, 4, the heat radiation aluminum pipe.
The specific embodiment
Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, air-pressure balancing device in the body, comprise: body spherical in shape, body is made up of top cover 1, middle casing 2 and base 3, be provided with luminescent device 21 in the middle casing 2 and the power device 22 of energy is provided to luminescent device, also be provided with elastic bag 23 in described middle casing 2, elastic bag 23 is arranged on the heat radiation aluminum pipe 4 in the body, and the passage on the elastic bag 23 is connected on the breather pipe 31 on the base 3 by tracheae 24.
As shown in Figure 1, the operation principle of the air-pressure balancing device in the body of this structure is: after body is subjected to long-time solar light irradiation, temperature in the body is higher, add the heat that power device 22 itself distributes, the middle casing temperature inside can progressively rise, rising along with temperature, air pressure in the middle casing 2 also can be along with rising, thereby compressing elastic bag 23 shrinks, the gas of elastic bag 23 is discharged from tracheae 24 and the breather pipe 31 that is interconnected with it, elastic bag 23 shrinks the space that makes in the middle casing 2 and increases, thereby the air pressure in the middle casing 2 is reduced, and plays the effect that reduces air pressure.When to the temperature step-down in the external world at night, the air pressure in the middle casing 2 also can step-down, and elastic bag 23 can be upspring automatically and be returned to original size.
Claims (3)
