Specific embodiment
To better illustrate the object, technical solutions and advantages of the present invention, with reference to the accompanying drawings and examples to the present invention
Specific embodiment be described in further detail.The following examples are intended to illustrate the invention, but is not limited to of the invention
Range.
The embodiment 1 of frame of the invention:
As shown in Figures 1 to 8, frame generally rectangular-shape in the present embodiment, frame include constituting each seamed edge of frame
Tubing 1 and the turning attachment device of eight corners of frame is set, tubing 1 is square tube in the present embodiment.
Turning attachment device includes an adapter 7, and setting at least two is for being inserted into corresponding tubing 1 on adapter 7
Connection unit in hole, since each turning of frame in the present embodiment is connected separately with three root canal materials 1, corresponding the present embodiment
It is also provided on middle adapter 7 there are three connection unit, any two in three connection units are orthogonal, and three connections are singly
Three reference axis of the overall distribution of member similar to rectangular coordinate system.
Connection unit includes fixed block 5 and latch segment 2, and fixed block 5 is wholely set with adapter 7 in the present embodiment.This reality
Apply that adapter 7 in example is generally cube-shaped, adapter 7 includes a box and is separately positioned on three of box corner
Column, three columns are vertical with box.One of them of three fixed blocks 5 is fixed on the box of adapter 7, other two
Fixed block 5 is separately fixed on corresponding two columns.It should be noted that be square tube by tubing 1 in this present embodiment, it is right
It answers, connection unit is rectangular-shape in the present embodiment, and the overall dimensions of connection unit are less than the internal orifice dimension of square tube.
It is fixed together between the fixed block 5 and latch segment 2 of connection unit by screw threads for fastening structure in the present embodiment, spiral shell
Line fastening structure includes screw rod part 4 and nut piece 3, and screw rod part 4 is bolt in the present embodiment, and nut piece 3 is hex nut.

Through-hole is counter sink 502.The through-hole penetrated for screw rod part 4 is also equipped on latch segment 2, through-hole is long hole 201 in the present embodiment.
The slot 203 for the insertion of corresponding nut piece 3 is additionally provided on latch segment 2, the width of slot 203 is slightly larger than six in the present embodiment
The slot bottom shape of the thickness of angle nut, slot 203 is adapted with the outer profile of hex nut, and slot 203 is by using such
The structure design limitation displacement and rotation of nut piece 3, so that nut piece 3 can only be moved along the depth direction of slot 203.
Slot 203 and long hole 201 in the present embodiment on same latch segment 2 connect, and the side aperture of long hole 201 is arranged in slot
On 203 cell wall.It should be noted that the length direction of long hole 201 is parallel with the depth direction of slot 203 in the present embodiment.
The contact surface of fixed block 5 and latch segment 2 for toward each other is angular guide surfaces 503 in the present embodiment, specifically
The present embodiment in fixed block 5 and latch segment 2 be quadrangular shape, two bottom surfaces of quadrangular are right-angled trapezium, right angle ladder
Side where shape bevel edge constitutes the angular guide surfaces 503 in the present embodiment.The setting of angular guide surfaces 503 is so that fixed block 5
When fixed by screw threads for fastening structure with latch segment 2, latch segment 2 can be generated along angular guide surfaces 503 lateral displacement (i.e. with
The axial perpendicular direction of screw rod part 4), in this way after connection unit is inserted into 1 inside of tubing, by constantly screwing screw rod part 4 i.e.
Latch segment 2 can be pushed towards the inner wall movement of tubing 1 and until shored on the inner wall of tubing 1, the active force of this interior tensioner
Meeting is so that the friction force between 1 inner wall of latch segment 2 and tubing increases, to realize the company of turning attachment device Yu tubing 1
It connects.It should be noted that when screwing screw rod part 4, the peripheral side of nut piece 3 can with the mutual block of internal groove side wall of slot 203, from
And the case where nut piece 3 is rotated together with screw rod part 4 is limited, and latch segment 2 is due to by angular guide surfaces 503 and tubing
The limitation of 1 inner wall also avoids the case where latch segment 2 is rotated together with screw rod part 4.When lateral displacement occurs for latch segment 2, by
It is moved closer in the distance between nut piece 3 and bolt head, the squeezing action power between nut piece 3 and bolt head will push locking
Block 2 is moved along angular guide surfaces 503, and screw rod part 4 can translate in long hole 201, and nut piece 3 can be from the slot of slot 203
Bottom is mobile to notch direction.
In order to further limit the traversing direction of latch segment 2, guide frame is provided between latch segment 2 and fixed block 5, originally
Guide frame includes the guide rail 501 being arranged on fixed block 5 and the guide groove 202 being arranged on latch segment 2, guide rail in embodiment
501 and guide groove 202 be disposed to extend each along the oblique direction of angular guide surfaces 503.Counter sink in the present embodiment on fixed block 5
502 are pierced by the middle part of guide rail 501, and the long hole 201 on latch segment 2 is pierced by from the slot bottom of guide groove 202.The setting of guide frame so that
Latch segment 2 can only be oriented along the oblique direction of angular guide surfaces 503 and move, and improve integrally-built stabilization in this way
Property.
Latch segment 2 is inserted into corresponding 1 inner hole of tubing for convenience, latch segment 2 is used for insertion tube in the present embodiment
The insertion end of 1 inner hole of material be it is tapered, i.e. the insertion end of latch segment 2 is provided with tapered head 204, tapered head 204 generally prism-frustum-shaped.
In order to avoid the cell wall of slot 203 stops the axial displacement of screw rod part 4, also set up on tapered head 204 in the present embodiment
There is the U-type groove 205 stretched out for screw rod part 4, the groove depth direction of U-type groove 205 and the groove depth direction of slot 203 are consistent.
Turning attachment device further includes the capping 6 for hiding 4 outer end of screw rod part (i.e. bolt head), and capping 6 passes through card slot
Structure is fixed on adapter 7, and notch includes fixture block 601 and card slot 701.As shown in fig. 7, the whole similar corner of capping 6
Shape, capping 6 include three square plates perpendicular to one another, are provided with a fixture block 601 in the two of them of three square plates, turn
There are two card slots 701 for the corresponding position setting of joint chair 7, and when capping 6 is buckled on adapter 7, two fixture blocks 601 are inserted into respectively
In corresponding card slot 701, to realize the fixation to capping 6.In order to enable the pressing clamping process of capping 6 is more smooth,
Two fixture blocks 601 are wedge type in the present embodiment.In order to further limit the displacement of capping 6, so that capping 6 is fixed more
Securely, it is additionally provided with position limiting structure on capping 6 and adapter 7, position limiting structure includes the limit being arranged in capping 6 in the present embodiment
