Description
Technical field
The utility model is related to gas buffer unit field, more particularly to a kind of gas buffering pressure-keeping device.
Background technology
Existing gas buffering pressure-keeping device, pressurize head leans on the reaction force of motor compression spring to the power that PCB applies, existing
Pressure sensor can only measure the size of power output, and when the timing of stroke one, spring force is changeless, but to be applied pressure
The PCB of power because carrier size or other factorses change when, board itself cannot be adjusted, and cause pressure on PCB just
Set scope can be exceeded, the size of spring force is directly proportional to the deformation of spring, and spring-compressed is more, and power is bigger, works as deformation
There is the change of very little scope, the power of output will exceed set scope, cause to damage to product.
Utility model content
The utility model ensure that pressure keeps mainly solving the technical problems that provide a kind of gas buffering pressure-keeping device
Stabilization, will not change because of the change of extraneous factor, and protection pressure sensor will not be damaged because of overload.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of gas buffering pressure-keeping is provided
Device, mainly includes：Adjustment block, side connecting plate, cylinder, pressure sensor, guide rail contiguous block, spring and pressurize head, it is described
Side connecting plate is set to L-type and upper end is secured by bolts in adjustment block lower section, and the cylinder is fixedly installed by connecting plate
In side connecting plate upper end, the piston rod of the cylinder is connected to pressure sensor one end by connecting pole, and pressure sensor is another
One end is connected to guide rail contiguous block by floating junction, and the pressurize head is arranged at the lower section of guide rail contiguous block, guide rail contiguous block
It is connected by spring between pressurize head.
Preferably, the externally connected drive device of the adjustment block.
Preferably, it is additionally provided with pressure-regulating valve at the cylinder.
Preferably, the guide rail contiguous block is set to L-type, and side edge is connected to side connecting plate by line slideway.
Preferably, it is provided with briquetting between the floating junction and guide rail contiguous block.
The beneficial effects of the utility model are：The utility model is by cylinder, pressure-regulating valve, floating junction and spring
Combination, ensure that pressure remained steady, will not change because of the change of extraneous factor, protect product not to be subject to crushing, together
When also protect the pressure sensor will not to be damaged because of overload.

Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Fig. 1 is referred to, the utility model embodiment includes：
A kind of gas buffering pressure-keeping device, mainly includes：Adjustment block 12, side connecting plate 11, cylinder 2, pressure sensor 4,
Guide rail contiguous block 6, spring 7 and pressurize first 8, the side connecting plate 11 is set to L-type and upper end is secured by bolts in adjustment
The lower section of block 12, the cylinder 2 is fixedly installed on the upper end of side connecting plate 11 by connecting plate 13, and the piston rod of the cylinder 2 leads to
Cross connecting pole 10 and be connected to the one end of pressure sensor 4, the other end of pressure sensor 4 is connected to guide rail and connects by floating junction 5
Block 6, the pressurize first 8 is arranged at the lower section of guide rail contiguous block 6, is connected by spring 7 between guide rail contiguous block 6 and pressurize first 8.
Operation principle of the present utility model is：During work, pressurize first 8 is fitted on PCB, is adjusted using gas pressure regulating valve
The air pressure of displacements of cylinders, makes it in a steady state value, and when external force pressure cylinder exceedes atmospheric pressure value, cylinder piston rod can be backward
Contracting, by pressurize first 8 loaded on the lower section of guide rail contiguous block 6, guide rail contiguous block 6 is connected on line slide rail 1 the utility model, works as spring
Power have also exceeded the pressure value of cylinder output because deforming while excess pressure exceedes setting value, after cylinder piston rod is to after-contraction
Spring deflection is reduced, is stopped when the two reaches balance, that is, ensure that the pressure being applied on PCB is one constant
Value.
The utility model retains original spring module part below 7, and a line slideway is added at the side rear portion of guide rail contiguous block 6
1, on side connecting plate 11, increased cylinder 2 is fixed on side connecting plate 11 line slideway 1, and cylinder piston rod connects
Connect post 10 to be connected with pressure sensor 4, pressure sensor 4 is flexible coupling by floating junction 5 and briquetting 9 with guide rail contiguous block 6, this
When sample external motivating force promotes whole module to move downward by adjustment block 12, pressurize first 8 stops after touching PCB, works as adjustment
Block 12 is continued traveling downwardly, and the pressuring spring 7 of guide rail contiguous block 6 applies pressure to pressurize first 8, and when pressure exceedes setting value, spring 7 is anti-
Active force bounces back after forcing the axial direction of cylinder 2, stops when spring 7 exerts oneself equal with the pressure of cylinder 2, and the at this moment gas of cylinder 2
Pressure setting value passes through air pressure regulator（Do not indicate）Just it is transferred to a required setting value.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
