Abstract
The utility model relates to an air pump pressure controller which comprises a base, a joint, a diaphragm, a pressure limiting spring, an instantaneously changing device and a contact device, wherein the joint is arranged on the base, and the diaphragm is arranged in an inner chamber of the joint. Through a jacking block, the diaphragm firmly presses and contacts a rocking plate of the instantaneously changing device and the pressure limiting spring in sequence. A spring plate of the instantaneously changing device is connected with a movable contact piece of the contact device. The edge of the base is made into a hemming shape, and a tension disc is arranged on the side plate. Because the ledge of the base is made into the hemming shape, the mechanical strength of the base is increased, and the base is not easy to deform. An electrical wire is fixed under the press of the tension disc on the side plate of the base, so the electrical wire is not easy to loose, and the reliability of the device is increased.
Description
Technical field
The utility model relates to the electric air pump parts, particularly to the improvement of pressure controller.
Background technique
On electric air pump, when reaching the upper and lower of setting, realizes pressure the purpose of control automatically in order to make it, on air pump, installed pressure controller.Currently used general structure is: the air pump pressure controller, comprise pedestal, joint, diaphragm, pressure limiting spring, instantaneously changing device, contact making device, pedestal is provided with joint, in the inner chamber of joint, diaphragm is set, the rocker of diaphragm by jacking block and instantaneously changing device, pressure limiting spring order successively press and contact, the springboard of instantaneously changing device is connected with movable touching plate in the contact making device, is shaped on plug-in pin or terminal screw on the static touching plate, in order to wiring.
On existing pressure controller, pedestal is a writing board shape, in use easily deforms, and influences working life; In addition, electric wire is connected on the static touching plate and from housing and passes, and does not have clamping fixture, poor reliability.
Summary of the invention
The utility model purpose is to provide a kind of bulk strength height, the air pump pressure controller of good reliability.
Scheme of the present utility model is: a kind of air pump pressure controller, comprise pedestal, joint, diaphragm, pressure limiting spring, instantaneously changing device, contact making device, pedestal is provided with joint, in the inner chamber of joint, diaphragm is set, the rocker of diaphragm by jacking block and instantaneously changing device, pressure limiting spring order successively press and contact, the springboard of instantaneously changing device is connected with movable touching plate in the contact making device, and wherein the flanging shape is made at the edge of pedestal, and side plate is provided with tension disc.
The utility model has the advantages that: the flanging shape is made at the edge of pedestal, has strengthened its mechanical strength, makes it not yielding; Electric wire is fixed by the tension disc crimping on the pedestal side plate, is difficult for becoming flexible, and has improved the reliability of device.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is a decomposition texture schematic representation of the present utility model.
Mark among the figure: 1 housing, 2 pressure limiting springs, the springboard of 3 instantaneously changing devices, the rocker of 4 instantaneously changing devices, 5 jacking blocks, 6 diaphragms, 7 joints, 8 outlet valves, 9 pedestals, 10 tension discs, 11 screws, 12 contact making devices.
Embodiment
As shown in the figure, the utility model comprises pedestal 9, joint 7, diaphragm 6, pressure limiting spring 2, instantaneously changing device, contact making device 12, pedestal 9 is provided with joint 7, be used for being connected with the gas holder of air pump, diaphragm 6 is set in the inner chamber of joint 7, the rocker 4 of diaphragm 6 by jacking block 5 and instantaneously changing device, pressure limiting spring 2 order successively press and contact, the springboard 3 of instantaneously changing device is connected with movable touching plate in the contact making device 12, wherein the flanging shape is made at the edge of pedestal 9, side plate is provided with tension disc 10, and tension disc 10 compresses by screw 11 electric wire is fixed.
Because the flanging shape is made at the edge of pedestal 9, has strengthened its mechanical strength, makes it not yielding; Electric wire is fixed by tension disc 10 crimping on pedestal 9 side plates, is difficult for becoming flexible, and has improved the reliability of device.
