Abstract
The invention relates to a waterproof pressure gauge. The waterproof pressure gauge comprises a dial, a pointer, a pressure gauge connector, a front cover, a sealing ring, a rear cover, a hose connector, a hose, a plug, a gear fixing rod, a gear fixing frame, a spring hose, a spring pull rod, and a gear transmission mechanism. The pressure gauge is fixed on equipment. The pointer is connected to the gear transmission mechanism. The cavity of the gauge is filled with hydraulic oil through the hose connector and the hose. The gear fixing rod is used to fix the gear transmission mechanism, and is fixed by the gear fixing frame to the rear cover. The spring pull rod is hinged to the gear transmission mechanism and the other end of the spring hose. The gear transmission mechanism is composed of two mutually-meshed gears and a spring. The advantage lies in that hydraulic oil is injected into the cavity of the existing pressure gauge to balance the pressure difference between the inside and outside of the gauge, the defect of the existing pressure gauge is overcome, and the waterproof pressure gauge has the characteristics of exquisite design, compact structure, low production cost and high reliability.
Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of waterproof homework equipment, specifically a kind of waterproofing pressure table.
Background technology
A few days ago, in environment, measure hydraulic pressure many employings bourdon gauges under water, be characterized in that structure is simple, durable, measurement range is wide, but this type of manometric shell does not adopt high pressure resistant design, can not meet and use in wet environment.If this type of manometric use degree of depth strengthens gradually, its shell first by pressure break, and finally damages.The deficiency of high pressure can not be born in order to overcome existing bourdon gauges, this patent improves on the basis of bourdon gauges, propose a kind of new waterproof tensimeter, namely in original tensimeter inner chamber injection liquid force feed, equalized pressure table inside and outside differential pressure, can make pressure balanced inside and outside pressure gauge housing, thus it is not enough to overcome existing tensimeter.This tensimeter aims at wet environment and designs, and has the low and reliability high of compact conformation, production cost, thus ensures normally to work in wet environment.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, provides waterproof homework equipment a kind of waterproofing pressure table.
According to technical scheme provided by the invention: described waterproofing pressure table comprises index dial, pointer, pressure tapping, table protecgulum, O-ring seal, watch back cover, hose adapter, flexible pipe, plug, gear fixed bar, gear fixed mount, spring hose, spring pull bar and gear drive, screw thread is passed through in described pressure tapping, pressure gauge is fixed on equipment, pointer is connected in gear drive (see figure 4), can be read the size of institute's measuring pressure by index dial.
As a further improvement on the present invention, described table protecgulum is clear glass, after mechanism various in pressure gauge has assembled, fixed by the screw thread in table protecgulum and watch back cover, O-ring seal plays sealing function therebetween, and described hose adapter is screwed on the threaded hole of watch back cover rear end face, and connects flexible pipe, when being full of hydraulic oil in pressure gauge inner chamber and flexible pipe, seal with plug shutoff.
As a further improvement on the present invention, described gear fixed bar is used for fixing gear drive, gear drive is fixed on watch back cover by gear fixed mount, described spring hose one end is connected with pressure tapping, described spring pull bar is hinged with the other end of gear drive and spring hose respectively, and described gear drive is made up of two pitch wheels and spring.
The present invention compared with prior art, advantage is: described waterproofing pressure table, by the mode of existing tensimeter inner chamber injection pressure oil, and balance sheet inside and outside differential pressure, overcome existing tensimeter not enough, there is the low and reliability high of deft design, compact conformation, production cost.

Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: the present invention forms primarily of index dial 1, pointer 2, pressure tapping 3, table protecgulum 4, O-ring seal 5, watch back cover 6, hose adapter 7, flexible pipe 8, plug 9, gear fixed bar 10, gear fixed mount 11, spring hose 12, spring pull bar 13 and gear drive 14, screw thread is passed through in described pressure tapping 3, pressure gauge is fixed on equipment, pointer 2 is connected to gear drive 14(and sees Fig. 4) on, the size of institute's measuring pressure can be read by index dial 1, in Fig. 2, described table protecgulum 4 is clear glasses, after mechanism various in pressure gauge has assembled, fixed by the screw thread in table protecgulum 4 and watch back cover 6, O-ring seal 5 plays sealing function therebetween, described hose adapter 7 is screwed on the threaded hole of watch back cover 6 rear end face, and connect flexible pipe 8, when being full of hydraulic oil in pressure gauge inner chamber and flexible pipe 8, seal with plug 9 shutoff, in Fig. 3, described gear fixed bar 10 is used for fixing gear drive 14, gear drive 14 is fixed on watch back cover 6 by gear fixed mount 11, described spring hose 12 one end is connected with pressure tapping 3, described spring pull bar 13 is hinged with the other end of gear drive 14 and spring hose 12 respectively, in Fig. 4, described gear drive 14 is made up of two pitch wheels and spring.
During embody rule, as shown in Figures 1 to 4, by flexible pipe 8 and the hose adapter 7 be arranged on watch back cover 6, transparent hydraulic oil is full of the inner chamber of pressure gauge and flexible pipe 8, and require that the amount by compression of flexible pipe 8 is greater than the compression total amount of the interior hydraulic oil of table at wet environment, when external pressure is delivered to spring hose 12 surface by hydraulic oil, its free end produces corresponding distortion, amplify through spring pull bar 13 and gear drive 14 again, by the pointer 2 be connected on gear drive 14, measured value is indicated on index dial 1.
