Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of medical hospital bed guardrail special handling tool, including reciprocating lever and 5 and
Shell 11 and lever 7 interconnected；The reciprocating lever 5 successively shell 11 and lever 7 described in activity grafting；The reciprocating lever 5
One end connect handle 8, the other end socket spring 10 simultaneously penetrate the shell 11；The reciprocating lever 5 is equipped with spring base 51；It is described
Spring base 51 abuts the spring 10；
Push handle 8 that reciprocating lever 5 can be made to travel forward, spring 10 is shunk；Handle 8 is unclamped, spring 10 is sprung back, reciprocating lever
5 returns.To avoid return is excessive from causing to be additionally provided with bayonet lock 6 on the reciprocating lever 5 in 5 retraction shell 11 of reciprocating lever；Bayonet lock 6 can
To be located in shell 11, can also be located in the head for being pierced by shell 11.
Coaxial runner 2 and gear ring wheel 3 are equipped in the shell 11；The runner 2 and gear ring wheel 3 can be rotated independently；
The outer ring of the gear ring wheel 3 is equipped with teeth；The reciprocating lever 5 is equipped with the helical tooth 9 engaged with the teeth.Reciprocating lever 5 is done
When reciprocating motion, the drive gear ring wheel 3 of helical tooth 9 is done to be rotated forward or backwards.
The inner ring of the gear ring wheel 3 is equipped with ratchet 1；The runner 2 is equipped with pawl 4 corresponding with the ratchet 1.Back and forth
When bar 5 advances, gear ring wheel 3 is rotated forward, and ratchet 1 pushes pawl 4 and then runner 2 is driven to rotate together；To make gear ring wheel 3 drive runner
When 2 rotation, uniform force.The quantity of the pawl 4 of the invention is two, and the two is in 180 ° of angles.Certainly, pawl 4
Quantity may be three or four, and 4 uniform ring of each pawl is located at the periphery of the runner 2；When rotation pawl 4 divide equally by
Power prolongs the service life.
When reciprocating lever 5 retreats, gear ring wheel 3 is inverted, and is skidded when ratchet 1 rotates with pawl 4, therefore runner 2 does not rotate.This hair
It is connected between the bright pawl 4 and runner 2 using torsional spring；To automatically reset when the skidding of pawl 4.
The runner 2 is also fixedly attached rotation axis 22；The rotation axis 22 penetrates the shell 11, and being in shell 11 can
