Abstract
The utility model discloses a sealing structure of a diaphragm air pump. The edge of a top cover extends downwards to form an extension rod, a barb is formed at the lower end of the extension rod, a sealing ring is arranged between the top cover and a press plate, and a step for hooking and positioning the barb is formed at the edge of a casing, so that the casing, a support, the press plate and the top cover are fixed together by the aid of hooked positioning between the barb and the step. Compared with the prior art, ultrasonic welding between the press plate and the top cover is omitted, the casing, the support, the press plate and the top cover are fixed together by the aid of hooked positioning between the barb and the step rather than ultrasonic welding and bolt connection, accordingly, the sealing structure is easy in processing, assembling and dissembling, cost for assembly is reduced, the sealing structure which is detached can be assembled secondarily conveniently, and components of the sealing structure can be replaced conveniently so as to guarantee product performance.
Description
Technical field
The utility model relates to the technical field of barrier film air pump, and is special relevant with its sealing configuration.
Background technique
In the prior art, the structure of barrier film air pump roughly is made up of housing, motor, cam, bearing, air bag group, compressing tablet, breather cheek valve, top cover and unidirectional gas outlet valve.
During use, gas enters air feed in the air bag of air bag group through breather cheek valve, and air bag group is alternately inflated under the drive of motor and cam, and gas is entered in the outlet chamber of top cover through unidirectional gas outlet valve, is squeezed in the inflatable object by air-inflating tube again, realizes inflation.
Though the depressed structure of concrete turnover of various barrier film air pumps is incomplete same, relevant patent also has much,, the package assembly of each member is but much at one.Usually, motor is fixedly mounted on the below of housing by screw, motor shaft stretches in the housing, cam is installed on the motor shaft, the support of air bag group is installed on the cam, bearing and compressing tablet cover successively on housing, and pass through screw together between housing, bearing and the compressing tablet, breather cheek valve is one-body molded on air bag group, air bag group is arranged between bearing and the compressing tablet, the air bag push rod of air bag group is fixed on the support, and unidirectional gas outlet valve is installed on the compressing tablet, and top cover is fixed on the compressing tablet by ultrasonic welding.
Therefore, all there is following defective in existing barrier film air pump:
One, adopt the mode of ultrasonic welding to be fixed together between compressing tablet and the top cover, this makes product processing comparatively bother, and processing cost is higher, and, in case the product moulding just can not be disassembled again, damage if run into inner unidirectional gas outlet valve, then can't change, and can only entire product abandon useless;
Two, bearing, compressing tablet and housing are to adopt the screw ways of connecting to be fixed together, and assembling is disassembled all very loaded down with trivial details, and, occur screw after disassembling easily and lose and cause the situation that can't assemble, influence the use of product.
In view of this, the inventor improves at above-mentioned barrier film air pump, makes great efforts a kind of sealing configuration of research and development, and to make things convenient for the barrier film air pump to assemble, to disassemble, change member, this case is arisen spontaneously.
The model utility content
The purpose of this utility model is to provide a kind of barrier film air pump sealing configuration, so that the barrier film air pump is assembled, to disassemble, change member all very convenient.
To achieve these goals, solution of the present utility model is:
Barrier film air pump sealing configuration, form extension rod downwards at the top cover edge, the lower end of extension rod forms barb, between top cover and compressing tablet, seal ring is set, edge at housing forms the step that colludes the extension location for barb, hang the location by colluding of barb and step, housing, bearing, compressing tablet and top cover are fixed together.
The corresponding side channel that passes through for extension rod that forms in the side of described housing, bearing and compressing tablet.
Offer positioning hole on the described top cover, the corresponding locating column that cooperates with positioning hole that upwards forms of compressing tablet.
Described unidirectional gas outlet valve and seal ring are one-body molded.
After adopting said structure, the utility model compared with prior art, saved the ultrasonic welding between compressing tablet and the top cover, utilized barb and colluding of step to hang the location and directly replace ultrasonic welding to be connected, housing, bearing, compressing tablet and top cover are fixed together with screw, so, it is all very easy that processing is assembled and disassembled, and assembly cost reduces, and disassembles the back secondary and assemble also very convenient, the replacing member is convenient, guarantees the use of product.

Embodiment
As depicted in figs. 1 and 2, be the preferred embodiment that the utility model discloses, the barrier film air pump is made up of housing 1, motor 2, cam 3, bearing 4, air bag group 5, compressing tablet 6, breather cheek valve 7, top cover 8 and unidirectional gas outlet valve 9.Sealing configuration of the present utility model, be to form extension rod 83 downwards at top cover 8 edges, the lower end of extension rod 83 forms barb 84, between top cover 8 and compressing tablet 6, seal ring 10 is set, edge at housing 1 forms the step 11 that colludes the extension location for barb 84, hang the location by barb 84 and colluding of step 11, housing 1, bearing 4, compressing tablet 6 and top cover 8 are fixed together.
In order to make product surface the same with existing product smooth, this embodiment is the corresponding side channel 12,42,63 that passes through for extension rod 83 that forms in the side of housing 1, bearing 4 and compressing tablet 6.Assembling is for convenience located, and this embodiment also offers positioning hole 85 on top cover 8, and compressing tablet 6 corresponding making progress form the locating column 64 that cooperates with positioning hole 85, so that assemble the location fast.In order to simplify structure, reduce member, this embodiment is one-body molded with unidirectional gas outlet valve 9 and seal ring 10.
Like this, the utility model has saved the ultrasonic welding between compressing tablet 6 and the top cover 8, utilization is colluded to hang to locate and is directly replaced ultrasonic welding to be connected with screw, it is all very easy to make product processing assemble and disassemble, assembly cost reduces, it is also very convenient to disassemble back secondary assembling, and it is convenient to change member, guarantees the use of product.
The utility model is applicable to the barrier film air pump of the depressed structure of various turnover, and the air pump of barrier film shown in this paper concrete structure is described below:
