Detailed description of the invention
Embodiment: a kind of anti-desktop stress decline protection mechanism, including upper pillar stand 1,
Lower pillar stand 2, top sheave 3, lower sheave 4, elastic component 5 and first and second stay cord 6,
7, what upper pillar stand 1 can slide is inserted in lower pillar stand 2, and top sheave 3 can turn
Moving and be positioned on the sidewall of upper pillar stand 1 upper end, lower sheave 4 can be rotatably positioned at vertical
On the sidewall of post 1 lower end, elastic component 5 upper end and upper pillar stand 1 upper end sidewall stationary positioned,
Described elastic component 5 along upper pillar stand 1 axial direction can stress elastic telescopic, first,
Two stay cord 6,7 upper ends are connected with top sheave 3 respectively, and first and second stay cord 6,7
Draw upper sliding after being wrapped in top sheave 3 surface one segment distance the most in a reverse direction
Wheel 3, the first stay cord lower end and elastic component 5 lower end stop location, the second stay cord lower end
Walk around lower sheave 4 to be connected with lower pillar stand 2.
During height of table top regulation, being pressed downward against desktop, the while that upper pillar stand 1 declining, second draws
Rope lower end rises after walking around lower sheave 4, and this results in the second stay cord upper end to lower sheave
Distance between 4 is shorter by, and upper cunning is rotated forward by the second stay cord effect,
Now, the longer distance in the first stay cord upper end is wrapped on top sheave 3, and first draws
The length of rope is shortened, then elastic component 5 is hauled compression, elastic component 5 by the first stay cord
Producing and be intended to overcome the reverse elastic force of the first stay cord pulling force, such desktop be press against decline
Time, elastic component 5 is understood the elastic anchorage force certain to desktop, is alleviated desk weight, make
People's regulation is the lightest.
Being additionally provided with sliding part 8, sliding part 8 can slide axially along upper pillar stand 1 and be positioned
On upper pillar stand 1, elastic component 5 lower end is fixing with sliding part 8 to be connected, under the first stay cord
End is connected with sliding part 8, is slided on upper pillar stand 1 by sliding part 8, it is to avoid the
One stay cord causes elastic component 5 phenomenon such as holding that deforms to occur when pulling, it is ensured that bullet
Property part 5 flexible normal.
The gathering sill slided for sliding part 8 it is additionally provided with on described upper pillar stand 1 medial wall,
Ensureing that sliding part 8 linearly slides up and down by gathering sill, sliding part 8 is preferably moulded
Materials and parts, it is to avoid wear and tear and slide smooth and easy.
Described elastic component 5 is air spring, it is also possible to be stage clip.
Described top sheave 3 periphery surface be formed respectively for first and second stay cord 6,
7 first and second grooves being wound around, are wound around for spacing first and second stay cord 6,7,
Avoid the two to interfere.
The first groove diameter on described top sheave 3 periphery surface is more than second
Groove diameter.
Being additionally provided with safety fastener 9 and insurance keeper 10, safety fastener 9 is fixedly installed in
On lower pillar stand 2, and safety fastener 9 can fixing with upper pillar stand 1 be connected, described insurance
Keeper 10 provides to safety fastener 9 to keep fixing setting of being connected with upper pillar stand 1
Determining retentivity, the second stay cord lower end is connected with safety fastener 9, and the second stay cord can be given
Safety fastener 9 provides the reverse tripping force for overcoming insurance keeper 10 retentivity,
Safety fastener 9 is hauled by the second stay cord the most all the time and is in open mode, i.e.
Released state is kept between itself and upper pillar stand 1, if elastic during life-time service
Part 5 damages, or the second stay cord breaks, and safety fastener 9 just loses pulling force, now bullet
Property part 5 support force of desktop is just failed, now, safety fastener 9 will be vertical with upper
Post 1 is fastened and connected under insurance keeper 10 effect, plays and does not allows desk fall down
Effect, it is to avoid desk stress is fallen downwards.
The structure that described safety fastener 9 can fixing with upper pillar stand 1 be connected is: upper pillar stand
The 1 radial direction jack 11 being provided with the arrangement of some axially spaced-aparts, lower pillar stand 2 is provided with energy
Enough with radial direction jack 11 position on upper pillar stand 1 just to hollow-out parts 12, safety fastener 9
It is articulated with on lower pillar stand 2 sidewall, and safety fastener 9 can be through the hollow-out parts of lower pillar stand 2
12 extend in the radial direction jack 11 of upper pillar stand 1, are rotated by safety fastener 9 and realize
With upper pillar stand 1 radially jack 11 and fasten and thread off, safety fastener 9 stands with upper in addition
Can also realize being fastened and connected and opening button, safety fastener 9 by fastener between post 1
Also can also is that and be positioned on lower pillar stand 2 along upper pillar stand 1 radial level Elastic Sliding
's.
