Specific implementation mode
With reference to Fig. 1 to Figure 12, the present invention is described further.
For the portable external fixing rack of the reduction of the fracture, including two fixed frame bodies, two fixed frame bodies it
Between it is equivalent or be unfolded by articulated shaft 22, each fixed frame body includes fixed seat 12 and connecting seat 20, the fixed seat 12
Be disposed with telescopic link assembly between the connecting seat 20, the articulated shaft 22 be arranged in two connecting seats 20 it
Between.The external fixing rack that the present invention designs substantially is folding structure, easy to carry.And it in use, can be according to the reality at synthetism
The length of border length adjustment external fixing rack.
After two fixed frame body expansion, fixed by least two bolts between two connecting seats 20,
And at least two dormant bolt holes are arranged on two connecting seats 20.
Spicule briquetting 11, the fixed seat 12 and spicule pressure are installed by least two bolts in each fixed seat 12
Correspondence is disposed with the groove that can place spicule on the opposite side of block 11, after locking each bolt, the fixed seat 12 and spicule
Groove on briquetting 11 corresponds to fastening can fixed bone spicule.The length direction of each groove is flexible with the link assembly
Direction is vertical.
Be disposed with the accommodating chamber stretched into for the link assembly in each fixed seat 12, the accommodating chamber include for
The opening that the link assembly passes through, the opening are disposed with the rotation axis 13 vertical with the link assembly axis, described turn
The middle part of moving axis 13 is disposed with the third through-hole passed through for the link assembly, the axis of the third through-hole and the rotation
The axis of axis 13 is vertical.
In the present embodiment, after external fixing rack expansion, two link assemblies are docked by fixed two connecting seats 20
It lengthens, two fixed seats 12 can swing adjustment position by corresponding rotation axis 13.
The link assembly includes that can stretch into the extension bar 21 of the accommodating chamber and fixed flexible with the connecting seat 20
Bar 23, the extension bar 21 are tube-in-tube structure, and the telescopic rod 23 can be stretched out from the tube-in-tube structure so that the connection rod set
Part increases.The side arrangement of the extension bar 21 has twice to crack, it is each it is described crack it is equal parallel with the axis of the extension bar 21,
Each described crack has tightened collar 24 on the extension bar 21 towards one end of the telescopic rod 23, the end.It is described
Collar 14 is tightened by screw thread, and tightens rear each closure tightening of cracking.In the present embodiment, cracks and be located at described in two
Opposite position, and the length cracked described in two is about 1/10th of 21 length of the extension bar.Therefore work as and adjusted length
After degree, you can fix the relative position of the telescopic rod 23 and extension bar 21 by tightening the collar 14.
In the present embodiment, along axis arrangement, there are two outer rack structure, each outer racks for the side of the telescopic rod 23
The flank profil of structure is unidirectional tooth, and the unidirectional tooth is exactly the flank profil structure similar with the ratchet gear teeth, and the telescopic rod 23 can be outside
It pulls out and can not directly push back.In opposite position, 21 medial surface of the extension bar is disposed with two outer rack structure bits
Two inner rack structures being meshed with each outer rack structure.When to shorten the length of the link assembly, institute is unclamped
Collar 14 is stated, and the telescopic rod 23 is rotated 90 °, keeps each outer rack structure de- with corresponding inner rack structure
From, you can the telescopic rod 23 is pushed back, then is inverted 90 ° and tightens the collar 14.
The extension bar 21 passes through the third through-hole, and the side wall of the third through-hole, which is disposed with, can withstand the extension bar
The trip bolt of 21 sides.The accommodating chamber is disposed with the second through-hole in the side wall of open-mouth, the axis of second through-hole with
The axis of the rotation axis 13 is vertical and is located at same level with the axis of the third through-hole.Screwdriver is passed through described the
Two through-holes are simultaneously directed at the third through-hole, you can turn the trip bolt.After the trip bolt is tightened, top without departing from
The side of the rotation axis 13, therefore the rotation axis 13 is not interfered to rotate at any angle.
The one end stretched on the extension bar 21 in the accommodating chamber is disposed at least one limit protrusion, each limit
Protrusion is located at the side of the extension bar 21, can prevent the extension bar 21 from deviating from from the third through-hole.In the present embodiment,
To ensure uniform force, the quantity of the limit protrusion is two, and is respectively at the opposite position in side.
Embodiments of the present invention are explained in detail above in association with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula, the technical field those of ordinary skill within the scope of knowledge, can also be before not departing from present inventive concept
Put that various changes can be made.
