Abstract
The present invention discloses a micro-gas-pressure indicator comprising a base with a front connector provided in the front and an interface provided at a side, wherein the interface is sleeved with a transparent case on which an air hole and a scale are provided; and a spring provided inside the transparent case with one end abutting against the top of the case and the other end connected with a sliding component capable of sliding on the inner wall of the case, wherein a stop part is provided below the sliding component. The micro-gas-pressure indicator in the present invention can indicate micro gas pressure by utilizing the proportional relation between the telescoping quantity of the spring and the gas pressure. The micro-gas-pressure indicator that can be obtained easily and can be used conveniently and durably is difficult of breakage and deformation.
Description
Technical field
The present invention relates to barometric indicator, specifically, is the micro gas-pressure indicator that is used to indicate amusement and recreation class aerated product air pressure about a kind of.
Background technology
Traditional air pressure indicating gauge is a kind of instrument that has dial plate, the dial plate of air pressure indicating gauge is provided with concrete scale, in design on the air pressure indicating gauge jointing that is complementary with the tuyere of inflating on the series products is arranged, this joint directly is inserted in the air valve that backs down tuyere on the tuyere, can directly read the air pressure of measurement from the dial plate; The effective measurement range of this air pressure indicating gauge is generally more than 0.15bar, and the inner gas pressure of general amusement and recreation class aerated product is all below 0.15bar, so such air pressure indicating gauge can't be popularized and is used for general amusement and recreation class aerated product.
In the patent No. that the inventor has authorized is in the utility model patent of 200420110834.X, discloses a kind of micro gas-pressure indicator, comprises pedestal, the front connector that the front end of pedestal is set, and the set transparent sheath body of pedestal side; The top of this transparent sheath body offers bleeder vent, and inside then is provided with a glue air-casing, on the transparent sheath body and indicate scale.This micro gas-pressure indicator stretches and indicates the numerical value of air pressure along with the variation of air pressure by the glue air-casing, but find in actual use, this glue air-casing is easier to break during use, and if the glue air-casing need not be sticked together for a long time, makes troubles to the user when reusing.
Summary of the invention
Purpose of the present invention just is to overcome the crackly defective of the existing glue air-casing of above-mentioned micro gas-pressure indicator, thereby a kind of new micro gas-pressure indicator is provided.
For achieving the above object, micro gas-pressure indicator of the present invention mainly comprises pedestal, and the pedestal front end is provided with a front connector, and the pedestal side is provided with an interface and sheathed one transparent sheath body, and this transparent sheath body is provided with bleeder vent and indicates scale; This transparent sheath body inside is provided with a spring, and an end of spring is resisted against the top of sheath body, and the other end then is connected with one can be along the sliding part of sheath body inwall slip, and the below of sliding part is provided with the stop section, to be used for the spacing of sliding part.
Particularly, the pedestal interface can be located in described stop section, also can be located at the below of sheath body.Described sliding part is provided with a cylindrical projections, and the external diameter of this projection just can sheathed spring, so that both are connected and fixed; The peripheral position that contact with sheath body of this sliding part is provided with a circle groove, a sheathed O-ring seal also on the groove, and to avoid excessive gas leakage, the while is also as the air pressure indication piece.
The spring of micro gas-pressure indicator of the present invention is spring material commonly used, can stretch along with the variation of indicator internal pressure, therefore can be according to the stroke and the air pressure magnitude proportion relation of spring, the scale on the corresponding transparent sheath body of dependence O-ring seal indicates the numerical value of air pressure.
Micro gas-pressure indicator of the present invention is not only simple in structure, and is easy to use, and draws materials easily, and cracky and distortion are not durable in use.

Embodiment
Architectural feature of the present invention is described further with specific embodiment below in conjunction with accompanying drawing.Should be understood that following examples only are used to the present invention is described but not are used to limit scope of the present invention.
As Figure 1-3, micro gas-pressure indicator of the present invention comprises that mainly one slightly is the pedestal 1 of drum shape, the front end of pedestal 1 is provided with a front connector 11, and base 1 side is provided with an interface 2 and is arranged with a transparent plastic sheath body 21, and sheath body 21 is provided with a bleeder vent 23 and indicates scale (figure does not show); Transparent sheath body inside is provided with a spring 22, and an end of spring 22 is resisted against the top of sheath body 21, and the other end then is connected with 24 of the slips that can slide along sheath body 21 inwalls, and the below of sliding part 24 is provided with stop section 27, is used for carrying out spacing to sliding part 24.
Particularly, pedestal interface 2 places can be located in described stop section 27, also can be located at the below of sheath body 21.Establish a cylindrical projections 25 on the sliding part 24, the external diameter of projection 25 just can sheathed spring 22, so that both are connected and fixed; Certainly, also can be provided with one at the position that sliding part 24 contacts with spring 22 and be able to block the groove of establishing spring, perhaps with glue spring 22 be sticked on the sliding part 24, these also are the scope of protection of present invention.
In addition, the peripheral positions that contacts with sheath body 21 of sliding part 24 are provided with a circle groove (figure does not show), a sheathed O-ring seal 26 also on the groove, and to avoid excessive gas leakage, the while is also as the air pressure indication piece.
Sliding part of the present invention 24 and the projection on it 25 adopt plastics or rubber materials, and the O-ring seal 26 on the sliding part 24 be the rubber material, and significant colors such as the employing people naked eyes color that is easy to discern such as black, redness, blueness, green.
The material of spring 22 of the present invention is spring material commonly used, and as carbon spring steel, alloy spring steel, stainless steel or Cu alloy material, spring 22 can be selected unlike material for use according to magnitude of load, the load character of material.Because spring has spring function, when the pressure in the indicator changes, it is flexible that sliding part 24 slides up and down drive spring 22, because transparent sheath body 21 is marked with corresponding scale, thereby can utilize O-ring seal 26 present positions to indicate corresponding air pressure numerical value according to the stroke and the air pressure magnitude proportion relation of spring 22.
As shown in Figure 2, be different from the other end A place of front connector and interface in the present embodiment on the pedestal 1, can add a back joint (figure do not show), in be provided with a retaining valve.Like this, micro gas-pressure indicator of the present invention can be realized with after air pump is connected, and observes air pressure while inflating.
In sum, micro gas-pressure indicator of the present invention is not only simple in structure, and is easy to use, and draws materials easily, and cracky and distortion are not durable in use.
