Specific embodiment
(F) before in the present invention, rear (B), left (L), right (R) are subject in Fig. 2 direction shown in cross axle.
Figure is please referred to, the present invention provides a kind of technical solution: a kind of conduit retainers, including on bottom plate 1 and bottom plate 1
Left and right fixture block 2,3.By the patch of adhered layer 4 on its bottom surface on skin, the relative inner of left and right fixture block 2,3 has bottom plate 1
Arc-shaped concave 8, conduit is placed between the arc-shaped concave 8 of left and right fixture block 2,3, and is clamped conduit by arc-shaped concave 8.On bottom plate 1
Two parallel sliding rails 5 of front and back, two sliding rails, 5 relative inner are provided with conduit 6, and the bottom of left and right fixture block 2,3 is equipped with slide plate 7, sliding
The rear and front end of plate 7 is slidably embedded in the conduit 6 of two sliding rails 5, to make left and right fixture block 2,3 that can horizontally slip in bottom plate 1.
Transverse-moving mechanism 9 drive left and right fixture block 2,3 and meanwhile to the left, to the right or simultaneously to the right, be moved to the left, i.e., left and right fixture block 2,3 can be same
Shi Xiangxiang is moved away from, and can just make arc-shaped concave by various outer diameter by adjusting the distance between left and right fixture block 2,3 in this way
Conduit clamp, enable conduit retainers of the invention to be suitable for intrathoracic drain, peritoneal cavity drainage tube picc pipe etc. various
The conduit of type.
The transverse-moving mechanism of above-mentioned left and right fixture block can be the spring for being connected to left and right fixture block 2,3 opposite exterior lateral sides,
It can be the cylinder etc. for respectively driving left and right fixture block 2,3.As shown in Fig. 2, the transverse-moving mechanism 9 in the present invention includes being positioned horizontally in
First connecting rod mechanism 10 and operating parts above left and right fixture block, first connecting rod mechanism 10 include the first left and right connecting rods 101,102
And the first push-pull rod 103 between the first left and right connecting rods 101,102, one end difference of the first left and right connecting rods 101,102
Hinged with left and right fixture block 2,3, the other end of the first left and right connecting rods 101,102 is coaxially articulated with one end of the first push-pull rod 103,
First push-pull rod 103 is located on left and right 2,3 or so median plane of fixture block, and the first left and right connecting rods 101,102 are symmetricly set on
The left and right of one push-pull rod 103.Operating parts drives the first push-pull rod 103 to be moved forward and backward.As shown in Fig. 2, when the first push-pull rod 103 to
When preceding mobile, the first left and right connecting rods 101,102 have the component to right and left to left and right fixture block 2,3 respectively, left and right in this way
Fixture block 2,3 can be close simultaneously, and the spacing of left and right fixture block 2,3 reduces, so as to clamp the lesser conduit of caliber.Together
Reason, when the first push-pull rod 103 moves backward, the first left and right connecting rods 101,102 respectively to left and right fixture block 2,3 have to the left and
Component to the right, fixture block 2,3 left and right in this way can be separate simultaneously, and the spacing of left and right fixture block 2,3 increases, so as to manage
The biggish conduit of diameter clamps.
Operating parts is the swivel nut 11 being threadedly engaged with the first push-pull rod 103, and 11 axial restraint of swivel nut, rotary threaded sleeve 11 can
So that the first push-pull rod 103 is moved forward and backward.
As shown in Fig. 2, the first left and right connecting rods 101,102 are in addition to having left and right when the first push-pull rod 103 moves forward
Outside the component in direction, also have forward component, the forward component acted on left and right fixture block 2,3 can make left and right fixture block 2,
Frictional resistance is generated between slide plate 7 on 3 and conduit 6, to influence the flatness that left and right fixture block 2,3 moves left and right.To solve
The problem of above-mentioned frictional resistance, transverse-moving mechanism 9 further include second connecting rod mechanism 12, second connecting rod mechanism 12 and first connecting rod mechanism
10 front and backs are symmetrical arranged, identical as the structure of first connecting rod mechanism 10, and second connecting rod mechanism 12 also includes the second left and right connecting rods
121,122 and the second push-pull rod 123 between the second left and right connecting rods 121,122, the one of the second left and right connecting rods 121,122
End is hinged with left and right fixture block 2,3 respectively, and the other end of the second left and right connecting rods 121,122 is coaxially articulated with the second push-pull rod 123
One end；Second push-pull rod 123 is threadedly engaged with the other end on swivel nut 11 with respect to the first push-pull rod 103, the first push-pull rod 103
Thread rotary orientation with the second push-pull rod 123 is on the contrary, the rotation of swivel nut 11 in this way can just make the first push-pull rod 103 and the second push-pull rod
123 forwardly and rearwardly move simultaneously.As shown in the lower part of figure 2, while the first push-pull rod 103 moves forward, the second push-pull rod
123 move backward, at this point, the second left and right connecting rods 121,122 have the component to right and left to left and right fixture block 2,3 respectively,
That is, the component and the first left and right connecting rods of the left and right directions of the left and right fixture block 2,3 of 121,122 pairs of the second left and right connecting rods
101, the component of the left and right directions of 102 pairs of left and right fixture blocks 2,3 is identical, moves left and right which increases left and right fixture block 2,3
External force.Simultaneously, the second left and right connecting rods 121,122 also have component backward to left and right fixture block 2,3 respectively, and this is backward
Component and 101,102 pair left and right 2 of the first left and right connecting rods, 3 forward component on the contrary, left and right fixture block 2,3 is by front and back in this way
External force on direction is just cancelled out each other, so that the frictional resistance of left and right fixture block 2,3 greatly reduces, left and right fixture block 2,3 or so is moved
It is dynamic more smooth.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill
For art personnel, it is clear that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from spirit of the invention or
In the case where essential characteristic, the present invention can be realized in other specific forms.Therefore, in all respects, should all incite somebody to action
