Abstract
The invention relates to an overturning control mechanism capable of being automatically folded. The overturning control mechanism comprises a handle and a fixed plate, wherein the handle is connected with one end of a handle connecting plate by virtue of a bolt; the other end of the handle connecting plate is connected with a cam sleeve by virtue of a fixed bolt; the cam sleeve is connected with a pulling spring hook plate by virtue of a reset linear pulling spring, and is also connected with a rotary shaft which is provided with a brake cable connecting rod; and the brake cable connecting rod is connected with a brake cable. The overturning control mechanism has the advantages that the brake cable can be driven to expand and retract, so that the releasing and locking of an air spring, and the two functions of folding and releasing control can be realized simultaneously by one comfortable action; due to newly-added folding function, the net space of the head of a medical staff can be effectively expanded, and the occurrence of the harmful event is avoided; the structure can be used for realizing modular preassembly and then can be fixed at a certain position of a product by bolts; according to the structural design, the factor of human-computer engineering is considered, so that the operation is more comfortable; and seen from the appearance, the matching of the overturning control mechanism with the whole body is more attractive.
Description
Technical field
The present invention relates to a kind of by rotary movement realize simultaneously folding and brake for controlling the handle system of medical spring arm lifting.
Background technology
At present, medical handle mostly cannot fold, so just cannot carry out modularity pre-assembled, to installation, bring difficulty, also cause the work of release back-moving spring sensitive not simultaneously, only have by twist grip energetically and make handle forward suitable position to, but the rotary manipulation wrist of getting up is uncomfortable like this, also has certain potential safety hazard.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of turning control mechanism of auto-folder, overcome the folding not problem of aspect of handle upset in the past, handle is folded up and is made medical personnel's above-head headroom, avoids the generation of the incident of injury.
The technical solution adopted for the present invention to solve the technical problems is: a kind of turning control mechanism of auto-folder, comprise handle and fixing head, handle is connected with handle connecting plate one end by bolt, the other end of described handle connecting plate is connected with cam sleeve by set bolt, cam sleeve hooks between plate and is connected by the extension spring of reset straight line with extension spring, cam sleeve is also connected with turning cylinder, and turning cylinder is provided with brake cable rank bar, and brake cable rank bar is connected with brake cable.
Further, the extension spring of reset straight line has one at least, can be according to the size of pulling force, and the extension spring of reset straight line can be installed one or install in fixing head both sides simultaneously.
Further, brake cable is arranged with brake cable fixing head outward, and fixedly brake cable, avoids the action of the wobble effects air spring of brake cable.
Further, in turning cylinder, be provided with rotating axle bushing, avoid turning cylinder with the direct friction of fixing head, extend the turning cylinder life-span, cost-saving.
Further, fixing head is connected and fixed bar by the second bolt.
The invention has the beneficial effects as follows: thus this mechanism can drive release and the locking of the flexible remote control gas spring of brake cable, by a comfortable action, can realize folding and two functions of control release simultaneously, newly-increased folder function can effectively increase the head headroom of medical personnel's work, avoid the generation of the incident of injury, it is pre-assembled that this structure can realize modularity, then by bolt, be fixed in certain position of product, compare with existing structure, saved the set-up time, this structural design has been considered human engineering factor, operate more comfortable, outward appearance, this mechanism and integral matching are more attractive in appearance.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
The turning control mechanism of a kind of auto-folder as shown in Figures 1 to 5, comprise handle 1 and fixing head 11, handle 1 is connected with handle connecting plate 2 one end by bolt 3, the other end of handle connecting plate 2 is connected with cam sleeve 6 by set bolt 5, cam sleeve 6 hooks 14 of plates with extension spring and is connected by reset straight line extension spring 9, cam sleeve 6 is also connected with turning cylinder 4, and turning cylinder 4 is provided with brake cable rank bar 10, and brake cable rank bar 10 is connected with brake cable 16; Reset straight line extension spring 9 has one at least; The outer brake cable fixing head 13 that is arranged with of brake cable 16; In turning cylinder 4, be provided with rotating axle bushing 7; Fixing head 11 is connected and fixed bar 12 by the second bolt 15.
With hands, down pull handle 1 o'clock, handle 1 starts the pulling force that overcomes reset straight line extension spring 9 down to rotate, owing to existing between cam sleeve 6 and turning cylinder 4, relative angle is poor to be connected, when cam sleeve 6 starts to rotate with handle 1, but turning cylinder 4 does not start to rotate, only have when cam sleeve 6 contacts with the boss of turning cylinder 4, just start to drive turning cylinder 4 to rotate, now brake cable rank bar 10 also rotates, thus the critical point that stretching brake cable 16 makes the locking switch of air spring 18 approach gradually stroke.When brake cable rank bar 10 finally touches the opposite side of spacing hole, locking switch, just in opening, completes dispose procedure.After loosing one's grip, handle 1 starts to reset under the effect of reset linear springs pulling force, and brake cable 16 is crossed rapidly stroke critical point under the pulling force effect of air spring 18 relieving mechanism contained springs simultaneously, completes lock function.
According to the size of pulling force, reset straight line extension spring 9 can settle one or both sides to settle simultaneously; According to the release travel of air spring 18, need the size of corresponding adjustment spacing hole; Adjust the differential seat angle of turning cylinder 4 and cam sleeve 6, the maximum open angle of capable of regulating handle; Fixing head can require change structure design according to actual installation.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
