Description
Technical field
The present invention relates to suspension bracket technical field, more particularly to a kind of new variable-force spring hanger.
Background technology
Variable-force spring hanger（Also referred to as variable spring support hanging frame, bullet are hung）The power conduit that is mainly used in having vertical displacement or
The supporting of equipment.Because it relies primarily on spring force to support load, therefore it is only suitable for being used in the less occasion of vertical displacement.Become
Power spring support hanging frame is built with cylindrically coiled spring, and while carrying, it adapts to the thermal walking of pipeline or equipment, can also inhale
The vibration in closed tube road, damping effect can be played simultaneously, plus it than constant supporting spring hanger economy, therefore allow in Stress calculation
In the case of, it is designed personnel and widely uses.
At present, it is to use compression spring in existing variable-force spring hanger, relies on compression spring when compressed
Caused elastic force supports the suspension rod of suspension pipe, and during long-term use of, the load capacity of compression spring can constantly decline,
And then service life is reduced, and increase security risk, mostly using by the form or inside and outside similar to series connection in existing patent
The mode of socket, to increase the number of compression spring, so as to extend service life, its defect is：The form of series connection can increase whole
The length of body variable-force spring hanger, increase installation difficulty；For the form of inside and outside socket during use is compressed, interior outer spring is easy
Generation touching friction, and not easy care.
The content of the invention
To solve the above problems, the invention discloses a kind of new variable-force spring hanger.
In order to reach object above, the present invention provides following technical scheme：
A kind of new variable-force spring hanger, it is characterised in that：Including the outer barrel being vertically arranged, it is provided with the top of the outer barrel
Top plate with boatswain chair, bottom are provided with bottom plate, upper arm-tie, extension spring, center platen are sequentially provided with from top to bottom in the outer barrel
And compression spring, the top plate are connected by bolt with upper arm-tie, the upper arm-tie and center platen can slide up and down setting
In outer barrel, the upper and lower ends of the extension spring are fixedly connected with the top of the bottom of upper arm-tie and center platen respectively, institute
The upper and lower ends for stating compression spring bear against the bottom of center platen and the top of bottom plate, are also set in the middle part of medium pressure plate bottom surface
There is suspension rod, the suspension rod upper end is fixedly connected with center platen, and lower end is through bottom plate middle part and is connected with flower basket bolt, the outer barrel
Circumferentially direction is evenly equipped with two bar shaped chutes to side wall, and the bar shaped chute is arranged on outer tube side wall from top to bottom, it is described on
Circumferentially direction is evenly equipped with two first projections for the side of arm-tie, and circumferentially to be evenly equipped with two second convex in direction for the side of medium pressure plate
Block, first projection and the second projection are slidably disposed in bar shaped chute.
Further, medium pressure plate bottom is provided with the first spacing collar.
Further, the external diameter of first spacing collar is identical with compression spring internal diameter.
Further, it is provided with the second spacing collar at the top of the bottom plate.
Further, the internal diameter of second spacing collar is identical with compression spring external diameter.
Further, it is arranged with locating ring on the outer barrel.
Compared with prior art, the beneficial effects of the present invention are：The side being combined using extension spring and compression spring
Formula, extension spring is set up above original center platen, so as to which when suspension rod suspension pipe loads, the center platen at the top of suspension rod exists
Simultaneously, the extension spring at top can apply upward pulling force to the elastic force applied upwards by bottom compression spring to it, so as to drop
The low load to compression spring, and then the service life of overall variable-force spring hanger is improved, reduce security risk；Using bolt
The position of upper arm-tie is adjusted, it is overall convenient and swift using regulation process so as to which conveniently regulating and controlling extension spring is to the pulling force of center platen.

Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.It should be noted that the word " preceding " used below in description,
" rear ", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outer " refer respectively to direction or remote
From the direction of particular elements geometric center.
As illustrated, a kind of new variable-force spring hanger, including the outer barrel 1 being vertically arranged, the top of outer barrel 1, which is provided with, to be carried
The top plate 3 of boatswain chair 2, bottom are provided with bottom plate 4, are sequentially provided with upper arm-tie 5, extension spring 6, the and of center platen 7 in outer barrel 1 from top to bottom
Compression spring 8, top plate 3 are connected by bolt 9 with upper arm-tie 5, and upper arm-tie 5 and center platen 7 can slide up and down and be arranged on outside
In cylinder 1, the upper and lower ends of extension spring 6 are fixedly connected with the bottom of upper arm-tie 5 and the top of center platen 7 respectively, compress bullet
