Abstract
The utility model discloses a kind of chest air spring support arm, comprise the otic placode of air spring, the backing plate of shape approximation " Z " type, " L " type of shape approximation, described air spring two ends are fixed on backing plate and otic placode respectively by screw, be connected to box house sidewall bottom described backing plate, bottom described otic placode, be connected to case lid inboard side edge position.Complete opening and closedown of case lid by the flexible of air spring, and air spring makes case lid opening procedure medium velocity slow, case lid has fixed the open position of case lid after opening, safe and reliable, time saving and energy saving.
Description
Technical field
The utility model relates to a kind of industrial equipment component of machine, is specially a kind of chest air spring support arm.
Background technology
Often use chest in the industrial production, comprise storage tank, instrument box, and equipment box minor shell etc. in industrial production, general chest, device housings etc. are provided with rotating shaft to realize opening and closedown of case lid between casing and case lid, but the rotation randomness of rotating shaft is larger, do not fix, case lid can be subject to gravity after opening, the impact of the various factors such as wind-force makes case lid be in uncontrollable state at any time, staff is mechanical to cabinet interior after case lid is opened, instrument, the process of components and parts is vulnerable to impact, the duty easily interrupting staff is even injured, and manual operation is wasted time and energy in case lid opening procedure.If after case lid is opened, case lid is fixing by latch, rope etc., open at case lid like this, lose time in closing process, energy is more.In addition, when the outdoor placement of equipment, if case lid is locked not in time, because the sealing of case lid and casing part does not have pretension, sleet dirt etc. can immerse casing, causes the damage of original paper in casing or aging.
Utility model content
The purpose of this utility model is to provide a kind of and is simply suitable for, time saving and energy saving, safe and reliable chest air spring support arm.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of chest air spring support arm, comprise air spring, the backing plate of shape approximation " Z " type, the otic placode of shape approximation " L " type, described air spring two ends are separately fixed on backing plate and otic placode, be connected to box house sidewall bottom described backing plate, bottom described otic placode, be connected to case lid inboard side edge position.
Described backing plate bottom is fixed on wall box by four screws, and described otic placode bottom is fixed on inside case lid by two screws.
Described air spring support arm is set to two, is symmetricly set on the both sides, inside of casing, case lid.
Described backing plate, otic placode material are corrosion resistant plate.
The beneficial effects of the utility model: the utility model structure is simple, adopt air spring energy storage, after during unlatching, case lid crosses center line, air spring extends automatically, and case lid jack-up is remained on desired location, without the need to adding the locking actions such as support or other latches; Time closed, because air spring is in extended state at closure state, make to produce seal preload between case lid and box sealing part, without the need to locking in time, between casing and case lid, just setting up reliable sealing, stop foreign object to enter casing; Case lid can freely be opened, and relative to some mechanical springs, air spring makes case lid opening procedure medium velocity slow, and case lid has fixed the open position of case lid after opening, safe and reliable, time saving and energy saving.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model air spring structure chart;
Fig. 2 is the utility model exemplary construction front view;
Fig. 3 is the utility model exemplary construction elevation.
Detailed description of the invention
Air spring is a kind of industrial equipment spare and accessory parts common on market, mainly plays support, buffering, braking, the highly effect such as adjustment and angular adjustment.As shown in Figure 1, described air spring 6 comprises piston system 7, piston rod 8, connector 9, screw 10.Its basic principle of air spring is in airtight cylinder body, be filled with the inert gas or gas mixture that are pressed with certain pressure reduction with ambient atmosphere, and then utilizes the pressure differential acted on piston rod 8 cross section to complete air spring freely-movable.Air spring has very significant advantage than common spring: speed relatively slowly, dynamic force change little (generally within 1:1.2), easily to control; With mechanical spring unlike, air spring has the elastic curve of near-linear.
As Fig. 1, the connector 9 of described air spring 6 entangles parcel screw 10, and is be in movable state, and when screw 10 is securing, described air spring 6 can rotate centered by screw 10.
As Fig. 2, Fig. 3, a kind of chest air spring support arm, described chest comprises casing 1, case lid 2, rotating shaft 3, rotating shaft 3 connect box 1 and case lid 2.Described chest air spring support arm, comprises air spring 6, backing plate 4, otic placode 5, and two terminal screws 10 of described air spring 6 are separately fixed on backing plate 4 and otic placode 5.
Be fixed on casing 1 sidewall by four screws bottom described backing plate 4, backing plate 4 mainly plays the effect of lifting, increasing, and air spring 6 can not be collided with casing 1 oral area edge in rotation, telescopic process.
Described otic placode 5 bottom is fixed on by two screws the position that to keep to the side inside case lid 2, corresponding with the backing plate 4 on the sidewall of casing 1 inner the same side, make case lid 2 air spring 6 after closedown be in the state of retraction, and backing plate 4, air spring 6 and otic placode 5 are on a nearly line.Described otic placode 5 plays the effect of stretching out, and air spring 6 can not be collided with case lid 2 in rotation, telescopic process.
In the use procedure of chest air spring support arm, open case lid 2, after case lid 2 crosses center line, air spring 6 works and automatically extends, and case lid 2 is slowly opened under the effect of air spring around rotating shaft 3.In opening procedure, the piston rod 8 of air spring 6 stretches out and air spring 6 rotates centered by its screw 10, reaches home until piston rod 8 stretches out, and case lid 2 jack-up is remained on desired location, without the need to adding the locking actions such as support or other latches; When after the task of finishing the work, case lid 2 is closed, because air spring is in extended state at closure state, make to produce seal preload between case lid and box sealing part, without the need to locking in time, between casing and case lid, just setting up reliable sealing, stoping foreign object to enter casing;
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described instantiation or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, the protection domain of utility model all should be belonged to.
