Description

Safety-type gas spring
Technical field
The utility model is related to gas spring equipment technical field, more particularly, to a kind of safety-type gas spring.
Background technology
Gas spring is widely applied in our life, such as support of the gas spring to chair, the support to desk Etc., existing gas spring is in failure, it is easy to cause to collide and damage between article, as placed many east on desk West or people lie prone it is first-class in desk, gas spring failure so that desk moment loses support force, so as to cause desk it is quick under Drop, causes the thing on desktop to slide, while will also result in injury to personnel, so as to cause unnecessary trouble.
Utility model content
The technical problems to be solved in the utility model is:In order to solve existing gas spring in failure, it is easy to cause object The problem of colliding and damaging between product now provides a kind of safety-type gas spring.
Technical solution is used by the utility model solves its technical problem:A kind of safety-type gas spring, including cylinder body And the piston rod on cylinder body is arranged on, supporting rod and limiting plate are further included, the limiting plate is arranged on the piston rod, described One end of supporting rod is rotatably arranged on the cylinder body, opens up limit hole on the limiting plate, and the limit hole is along the Boring mill To setting, the cross-sectional shape of the limit hole is stepped structure, and the ladder-type structure of the limit hole is gradual from top to bottom Close to piston rod direction, one end far from its hinge joint of the supporting rod is worn on the limit hole.By in gas spring With limit hole on upper setting limiting plate, then supporting rod and limiting plate from being arranged on cylinder body, when piston rod rises to one When determining height, supporting rod is just supported in the hierarchic structure of limit hole, when gas spring fails, by supporting rod to piston rod into Row support, prevents piston from quickly falling after rise.
In order to enable supporting rod can preferably be supported piston rod, further, further include screw rod, fixing sleeve and Nut, the screw rod are arranged on the cylinder body, and the central axis of the screw rod and the central axis of the cylinder body intersect Setting, the nut thread are connected on screw rod, and the fixing sleeve is rotatably arranged on the nut, and the supporting rod is hinged on On the fixing sleeve.By rotating nut, fixing sleeve displacement on screw rod is driven, adjusts the angle between supporting rod and cylinder body, So that supporting rod can preferably be supported piston rod.
Nut falls screw rod in order to prevent, and further, the one end of the screw rod far from cylinder body is provided with limited block.Pass through The phenomenon that limited block on screw rod is set, nut rotation is effectively prevent to fall out screw rod.
The beneficial effects of the utility model are:The safety-type gas spring of the utility model when in use, passes through the piston rod upper limit Supporting rod cooperation on the limit hole and cylinder body of position block, when piston rod stretches out, supporting rod is effectively supported piston rod, carries The high safety of gas spring, avoids existing gas spring in failure, it is easy to it causes to collide and damage between article, As placed many things on desk or people lies prone, gas spring failure so that desk moment lose support first-class in desk Power so as to cause desk rapid decrease, causes the thing on desktop to slide, while will also result in injury to personnel, so as to cause not Necessary trouble.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model;
Fig. 2 is the partial enlarged view of A in Fig. 1;
Fig. 3 is structure diagram when the utility model supporting rod is in holding state.
In figure:1st, cylinder body, 2, piston rod, 3, supporting rod, 4, limiting plate, 401, limit hole, 5, screw rod, 6, fixing sleeve, 7, Nut, 8, limited block.
Specific embodiment
Presently in connection with attached drawing, the utility model is described in more detail.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
Embodiment
As shown in Figs. 1-3, a kind of safety-type gas spring including cylinder body 1 and the piston rod being arranged on cylinder body 12, is also wrapped Supporting rod 3 and limiting plate 4 are included, the limiting plate 4 is fixed on the piston rod 2, and one end of the supporting rod 3 is rotatably arranged on institute Cylinder body 1 is stated, limit hole 401 is opened up on the limiting plate 4, the limit hole 401 is set along the cylinder body 1 is axial, the limiting The cross-sectional shape in hole 401 is stepped structure, and the ladder-type structure of the limit hole 401 is from top to bottom gradually to piston rod 2 Direction is close, and one end far from its hinge joint of the supporting rod 3 is worn on the limit hole 401.
Screw rod 5, fixing sleeve 6 and nut 7 are further included, the screw rod 5 is arranged on the cylinder body 1, one end weldering of screw rod 5 It is connected on cylinder body 1, the central axis of the screw rod 5 and the central axis of the cylinder body 1 are arranged in a mutually vertical manner, 7 spiral shell of nut Line is connected on screw rod 5, and the fixing sleeve 6 is rotatably arranged on by bearing on the nut 7, and the supporting rod 3 is hinged on institute It states on fixing sleeve 6.
The described one end of screw rod 5 far from cylinder body 1 is welded with limited block 8.Between 7 displacement cylinder body 1 of nut and limited block 8.
For above-mentioned safety-type gas spring when using, concrete operation step is as follows:The nut 7 on screw rod 5, nut are rotated first 7 displacements on screw rod 5 drive 6 displacement of fixing sleeve, so as to adjust the position of screw rod 5 on fixing sleeve 6, that is, adjust supporting rod Angle between 3 and cylinder body 1 so that supporting rod 3 can be preferably slided into limit hole 401, and to work under its own gravity Stopper rod 2 is supported, and completes the adjusting of supporting rod 3;When piston rod 2 stretches out, supporting rod 3 slides in limit hole 401, works as work When stopper rod 2 reaches certain altitude, supporting rod 3 is gradually drawn close under the effect of gravity to the hierarchic structure direction of limit hole 401, is made Supporting rod 3 is supported in the hierarchic structure of limit hole 401, when do not need to be supported bar 3 piston rod 2 is supported when, pass through Manually supporting rod 3 is made to dial the hierarchic structure from limit hole 401;When gas spring fails, piston rod 2 can decline rapidly, due to Supporting rod 3 is supported limiting plate 4, so piston rod 2 will not have a declining tendency, ensure that 2 supporting & stablizing of piston rod.
The above-mentioned desirable embodiment according to the utility model is enlightenment, passes through above-mentioned description, relevant staff Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical Novel technical scope is not limited to the content on specification, it is necessary to determine that its is technical according to right Range.
