Irradiation, but when carrying out chest, the larger target area such as abdominal cavity and treatment of nasopharyngeal carcinoma, then carry out the grating of small opening and be just not suitable for controlling
Treat, must just use block technology.Such as：When treating rhinitis cancer, fixed, made according to the scope of infringement individual using thermoplastic mask
Bodyization gear lead design, can be effectively protected and close on important organ, shield block can accomplish with target area height it is conformal, accurately put
The purpose for the treatment of.
Generally there is two kinds of metal, one kind is refined lead, mainly pure lead, and one kind is antimonial lead, and one kind is lead and hard
The alloy of metal.Pure lead is melted in 621 degree, and has and pour into a mould feature well in 700-800 degree.Refined lead generally can be by thumb
Nail enters.Pure lead is most soft in all metals, can pinch out print with finger nail, pure lead radiation-proof effect is good, therefore tumour is put
Pure lead lead is often used during treatment and carrys out radiation proof, current lead is all a monoblock, and shape and human body compactness be not high.This
For in place of the deficiencies in the prior art.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of tumor radiotherapy lead protector v-shaped groove pressurizing unit so that
Lead and human body compactness are more preferable during tumor radiotherapy.
The utility model, which adopts the following technical scheme that, realizes goal of the invention：
A kind of tumor radiotherapy lead protector v-shaped groove pressurizing unit, including workbench, it is characterized in that：It is solid above the workbench
Surely there are four structure identical screw rods, lifting disk, lifting disk both sides limited location are placed between four screw rods
Post is passed through, and the limited post is also stood on the workbench, and branch is provided with equipped with vertical rail, the vertical rail top on the workbench
Support one, motor support base one is installed on support frame as described above one, motor one, the motor one are installed on the motor support base one
Flap is connected with output shaft, the flap is hinged with draw back plate one end, and the draw back plate other end is hinged on lifting column, described
Lifting column is arranged in the pilot hole of vertical rail, is connected with the lifting column by hammer, the workbench side is fixedly connected with
Determine block, the fixed block connects support frame two, passes through the connection motor two of motor support base two, the motor two on support frame as described above two
Output axis connection driving gear, the driving gear engages four driven gears respectively, the center of each driven gear
Axle connects four screw rods respectively through the workbench, and the central shaft of each driven gear is arranged on by bearing
On the workbench.
As the further restriction of the technical program, the motor one and the motor two select threephase asynchronous
Y132S-5。
Prior art is compared, and the advantages of the utility model and good effect is：The utility model is completely by motor one and electricity
Machine two provides power, saves the working time, improves operating efficiency, drives lifting disk to push lead by screw rod, simplifies
Transport technique, ensure that lead steadily lifts, and motor one drives flap, draw back plate, lifting column and lead is carried out by hammer
Pressing produces V-groove, and the lead with V-groove is more preferable than the lead of plane and the compactness of human body, improves the anti-spoke of lead
Penetrate effect.

Embodiment
Below in conjunction with the accompanying drawings, an embodiment of the present utility model is described in detail, it is to be understood that this
The protection domain of utility model is not limited by embodiment.
As Figure 1-Figure 5, the utility model includes workbench 7, and it is identical that the workbench 7 is fixedly arranged above four structures
Screw rod 6, be placed with lifting disk 12 between four screw rods, the corner of lifting disk 12 is individually positioned in screw rod 6
In helical duct, lifting disk 12 can follow the rotation and lifting of screw rod 6, and the both sides limited location post 13 of lifting disk 12 passes through,
The limited post 13 is also stood on the workbench, and support is provided with equipped with vertical rail 4, the vertical top of rail 4 on the workbench 7
Frame 1, motor support base 1 is installed on support frame as described above 1, motor 1, the electricity are installed on the motor support base 1
Flap 16 is connected with the output shaft of machine 1, the flap 16 is hinged with the one end of draw back plate 15, and the other end of draw back plate 15 is hinged on
On lifting column 5, the lifting column 5 is arranged in the pilot hole 19 of vertical rail 4, is connected with the lifting column 5 by hammer 14, the work
Make the side of platform 7 and be fixedly connected with fixed block 11, the fixed block 11 connects support frame 2 10, passes through electricity on support frame as described above 2 10
Machine bearing two connects motor 28, the output axis connection driving gear 17 of the motor 28, and the driving gear 17 engages respectively
Four driven gears 18, the central shaft of each driven gear 18 connect four screw rods respectively through the workbench
6, the central shaft of each driven gear is arranged on the workbench 7 by bearing (known technology, figure not shown in).
The motor selects threephase asynchronous Y132S-5.
At work, motor 28 provides power to the utility model, drives driving gear 17 to rotate, driven gear 18 follows
Driving gear 17 rotates, and then drives the screw rod 6 that is linked together with driven gear 18 to rotate respectively, due to lifting disk 12
