Abstract
The utility model discloses an air pressure balancing device in lamp cap body capable of leading the air pressure in the lamp cap body to maintain balance, which comprises the lamp cap body; the lamp cap body consists of a top cap, a middle shell and a base; the middle shell is provided with a luminescent device and a power device providing energies to the luminescent device; the middle shell is also provided with an elastic air sac; a venthole on the elastic air sac is connected onto a breathing pipe on the base by an air pipe. The air pressure balancing device in lamp cap body has the advantages that the air pressure balancing device in lamp cap body of the structure can lead the air pressure in the lamp cap body to maintain balance and prevent the middle shell from expansion and cracking.
Description
Technical field
The utility model relates to the body that is used for traffic lights, relates 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.
The utility model content
Technical problem to be solved in the utility model 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, the technical solution of the utility model 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 utility model 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 utility model is: described body is spherical in shape.
The utility model has the advantages that: 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 utility model body.
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 utility model 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)
1, 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, it is characterized in that: 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.
2, the air-pressure balancing device in the body according to claim 1 is characterized in that: described elastic bag is arranged on the interior heat radiation aluminum pipe of body.
