Abstract
The invention provides a buffer device applied to a lifting guardrail, which comprises a guardrail piece, a guardrail base, a main supporting connecting rod, an auxiliary supporting connecting rod and a metal tension spring, wherein the base end of the auxiliary supporting connecting rod is provided with an integrated eccentric perforation cam around a rotating shaft, and a tension spring interface is correspondingly arranged on the guardrail base; and the metal tension spring is in bridge connection between the eccentric perforation cam and the tension spring interface. Compared with a gas spring, the structure is simpler, the use is more reliable, the cost is lower, and the popularization and the use are more favorable.
Description
Technical field
The present invention relates to a kind of buffer unit, especially a kind of buffer unit that is applied to hoisting type guard rail, this device can make the cost of hoisting type guard rail lower, use safety and reliability.
Background technology
Along with the improvement of medical condition and the consideration of medical safety, existing medical bedstead all universal demand is installed guardrail, and for this reason, the kind of medical bedstead guard bar device and style are all in constantly development, renewal on the market.
Adopt in succession like Japan eight happy dream beds industry company etc. and can upwards launch and the hoisting type guard rail that draws in downwards, said hoisting type guard rail device good looking appearance, easy to use and human oriented design particularly receive the favor of medical institutions.
Said hoisting type guard rail is made up of assemblies such as guardrail sheet, guardrail base, supporting master connecting-rod, supporting slave connecting rod, cushion gas springs.When needs draw said hoisting type guard rail in, will produce bigger impulsive force if let alone free-falling, possibly cause associated components to damage.Common way is to adopt an end to be connected in the supporting master connecting-rod, and the air spring that the other end is connected in the guardrail base provides cushion effect, thereby prevents parts damages and guarantee safe in utilization is provided, and is as shown in Figure 1.
Though the buffer unit that this application air spring air pressure inside changes can play cushioning effect to the gathering of guardrail, because the air spring complex structure, manufacturing cost and use cost is higher, and the phenomenon generation that loses pooling feature because of the air pressure leakage is often arranged.
Thereby, how to design a kind of buffer technology that can be applied to hoisting type guard rail device, to avoid deficiency of the prior art, real is insider and the present urgent problem of correlational study person.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, a kind of buffer unit that is applied to hoisting type guard rail be provided, make that it is simple in structure, reliable effectively, be easy to assembly operation and cost is low helps applying.
For realizing above-mentioned purpose, the present invention adopts following design:
A kind of buffer unit that is applied to hoisting type guard rail; Comprise guardrail sheet, guardrail base, supporting master connecting-rod, supporting slave connecting rod, metal extension spring; It is characterized in that; The base end of supporting slave connecting rod offers eccentric punch cam around rotating shaft, on the guardrail base, is shaped on the extension spring interface accordingly, and metal extension spring cross-over connection is between eccentric punch cam and extension spring interface.
Be simplified structure, said supporting slave connecting rod and eccentric punch cam are formed in one.
The present invention has following beneficial effect:
1. be equiped with the hoisting type guard rail of said buffer unit, when needs launched guardrail, said bolster metal extension spring took place to draw high motion accordingly, thereby to the expansion campaign of guardrail sheet castering action is provided; When needs drew guardrail in, corresponding contractile motion took place in the extension spring of said bolster metal, thereby to the contractile motion of guardrail sheet cushioning effect is provided.
2. said buffer unit adopts the metal extension spring as bolster, and structure is simpler for air spring, use is more reliable, cost is lower more helps promoting the use of.
3. support the integrated formed structure of slave connecting rod and eccentric punch cam, both simplified the syndeton of bolster, reduced the complexity that bolster is installed again, further reduced the required human cost of production.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Shown in accompanying drawing, a kind of buffer unit that is applied to hoisting type guard rail comprises guardrail sheet, guardrail base, supporting master connecting-rod, supporting slave connecting rod, metal extension spring.On the basis of existing technology; For the ease of manufacturing; Reduce production costs, offer integrated eccentric punch cam around rotating shaft, on the guardrail base, be shaped on the extension spring interface accordingly in the base end that supports slave connecting rod; Metal extension spring cross-over connection is between eccentric punch cam and extension spring interface, and structure is simpler for air spring, use is more reliable, cost is lower more helps promoting the use of.
The described punch forming structure that is positioned on the guardrail base as the extension spring interface; Under the prerequisite that realizes identical function; Also can be other shape and structure designs; Adopt assembled or on base, directly be shaped on structural design scheme such as other shape metal extension spring connecting interface like guardrail base and extension spring interface, do not have specific limited.
The said eccentric punch cam supporting slave connecting rod that offers; Under the prerequisite that realizes identical function; Also can be other shape and structure designs, adopt assembled or eccentric cam to adopt structural design schemes such as semicircle, do not have specific limited like supporting slave connecting rod and eccentric punch cam.
Said hoisting type guard rail is by guardrail sheet, guardrail base, supporting master connecting-rod, supporting slave connecting rod, and assemblies such as metal extension spring are formed.
Wherein, When needs launch and draw said hoisting type guard rail device in; The metal extension spring is connected in that relative displacement does not take place extension spring interface one end on the guardrail base, and is connected in the motion of eccentric punch cam one end along with cam, and the generation of spring body own draws high and contractile motion accordingly; Thereby for hoisting type guard rail provides corresponding buffering and castering action, for user especially medical patient provides guarantee safe in utilization.
