Abstract
The utility model discloses a micro-pressure indicator. The front end of a base is provided with an opening and connected with a front joint, the base is provided with an interface, and the interface is sheathed with a transparent sleeve shell; the top of the transparent sleeve shell has air vent, a glue air sleeve is arranged inside the transparent sleeve shell and the transparent sleeve shell is marked with scales. The micro-pressure indicator can utilize proportional relation between the telescoping quantity of the glue air sleeve and atmospheric pressure to indicate the atmospheric pressure. Besides, the utility model is convenient in operation and can greatly reduce production cost.
Description
Technical field
The utility model 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.
Summary of the invention
The purpose of this utility model just is to overcome the shortcoming that traditional air pressure indicating gauge can't be measured for infrabar, thereby a kind of hypobaric micro gas-pressure indicator that is used to measure amusement and recreation class aerated product is provided.
For achieving the above object, micro gas-pressure indicator of the present utility model comprises that mainly one slightly is the pedestal of drum shape, and the front end of pedestal is provided with an opening and is connected with a front connector, on the pedestal and be provided with an interface, be arranged with a transparent sheath body on this interface, both are with glue or be threaded; The top of transparent sheath body offers a little bleeder vent, and inside then is provided with a glue air-casing, on the transparent sheath body and indicate scale.
The utility model also can be provided with a back joint at the other end of drum shape pedestal, and establishes a retaining valve in the joint of back.
The glue air-casing of micro gas-pressure indicator of the present utility model adopts latex or rubber material, can stretch along with the variation of air pressure, therefore can be according to the stroke and the air pressure magnitude proportion relation of glue air-casing, rely on scale on the transparent sheath body to indicate the numerical value of air pressure, this numerical value can be much smaller than 0.15bar, even the air pressure that can indicate 0.02-0.04bar.The setting of joint then more can make indicator while inflating the inner gas pressure of observing in the aerated product.
As seen, micro gas-pressure indicator of the present utility model is not only simple in structure, and is easy to use, and draws materials easily, and cost of products is declined to a great extent.

Fig. 2 is the diagrammatic cross-section of micro gas-pressure indicator of the present utility model;
Fig. 3 is located at the synoptic diagram of the pedestal other end for interface of the present utility model;
Fig. 4 is the diagrammatic cross-section of another embodiment of the utility model.
Embodiment
Architectural feature of the present utility model is described further with specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, 2, micro gas-pressure indicator of the present utility model comprises that mainly one slightly is the pedestal 1 of drum shape, the front end of pedestal 1 is provided with an opening 3 and is connected with a front connector 11, and side is provided with an interface 2, be arranged with a transparent plastic sheath body 21 on this interface 2, both are with glue or be threaded; The top of transparent plastic sheath body 21 offers a little bleeder vent 23, and inside then is provided with a glue air-casing 22, on the transparent sheath body 21 and indicate scale (figure do not show).
As shown in Figure 2, the terminal inner edge of opening 3 is provided with shoulder 4, and the junction of front connector 11 and opening 3 is made as elasticity overhead kick 12, relies on elasticity overhead kick 12 to catch on shoulder 4 and realizes connecting; And front connector 11 front end embedding and injection moldings have peg 13, in order to back down the retaining valve in the tuyere when inserting the tuyere of aerated product.
The material of glue air-casing 22 of the present utility model is used latex or rubber, like this, glue air-casing 22 can stretch along with the variation of air pressure, because transparent sheath body 21 is marked with corresponding scale, and glue air-casing 22 can select for use the latex of unlike material or different-thickness or rubber to change its elasticity, therefore the numerical value that can indicate air pressure according to the stroke and the air pressure magnitude proportion relation of glue air-casing 22.And because the top of transparent sheath body 21 offers bleeder vent 23, when glue air-casing 22 stretches, extraneous air can pass in and out sheath bodies 21 from bleeder vent 23, thereby makes the interior air of cavity of plastic housing 21 tops, glue air-casing 22 outsides keep normal pressure, and then guarantees the accuracy of the little air pressure indication of indicator.(YE-100 type stainless steel bellows tensimeter, last Haixing County's religion instrument and meter factory) after measured, micro gas-pressure indicator minimum of the present utility model can be indicated the air pressure of 0.02-0.04bar, much smaller than the 0.15bar of traditional air pressure indicating gauge.
In another embodiment of the present utility model, joint 15 after the other end of pedestal 1 is provided with, as shown in Figure 4, its with the inwall of pedestal 1 by glue or be threaded, in be provided with a retaining valve 16.Like this, micro gas-pressure indicator of the present utility model can be on one side to the product inflation, Yi Bian observe the interior inner gas pressure of product.
In sum, micro gas-pressure indicator of the present utility model is not only simple in structure, and is easy to use, and draws materials easily, and cost of products is declined to a great extent.
