Embodiment 1
Please refer to Fig. 1~3, in the embodiment of the present invention, a kind of pre- apparatus for heat sealing with self-locking function, including fixed plate 1, wear
Cross fixed plate 1 and be slidably connected therewith sliding sleeve 3, be fixed on 3 lower part of sliding sleeve tooth plate 7, be rotatably arranged on the lower section of fixed plate 1
Worm screw 8, the worm gear 10 engaged with worm screw 8 and the gear 11 being fixedly connected with worm gear 10, wherein the rear side of the fixed plate 1
Top is fixedly connected with connecting column 6, and the rear portion of connecting column 6 is fixedly connected with mounting plate 5, and 8 both ends of worm screw are connected to by bearing respectively
In fixed plate 1 and mounting plate 5, and the regulating wheel being adjusted for the rotation to worm screw 8 is fixedly connected at the rear portion of worm screw 8
9, drive worm screw 8 to rotate by rotation regulating wheel 9.
Further, the worm gear 10 is rotatably arranged on the rear side of fixed plate 1 with gear 11, and gear 11 be fixed on
The tooth plate 7 of 3 lower part of sliding sleeve is meshed, and the center of sliding sleeve 3 offers the guide groove 19 for being adapted and being slidably connected with guide rod 4, guiding
The rear end of bar 4 is fixedly connected on mounting plate 5, drives worm gear 10 to rotate by the worm screw 8 of rotation, so that gear 11 be driven to follow
Rotation, gear 11 is slided with moving tooth plate 7 and sliding sleeve 3 along guide rod 4, final to drive sealing-plug 2 mobile, realizes the sealing to pipe fitting
It stoppers, since Worm Wheel System has the function of unidirectional self-lock, i.e., only worm screw 8 can drive worm gear 10 to rotate, and worm gear 10 is simultaneously
Worm screw 8 cannot be driven to rotate, therefore, after rotation regulating wheel 9 is fixed by sealing-plug 2, even if when pipe fitting is preheated
Expansion will not make sealing-plug 2 step down, and have self-locking function.
In order to preferably to being fixed at fixed plate 1 and the collar extension of pipe fitting, prevent to shake, in the fixed plate 1
It is additionally provided with fixed mechanism, the fixed mechanism includes by the driven shaft 14 of bevel gear set connecting worm 8, by driving member 15
It connects the thread bush 16 of driven shaft 14 and is threaded in the screw rod 17 on 16 top of thread bush, wherein the upper end of screw rod 17 is solid
Surely it is connected with the grip block 18 connecting with 1 side walls of fixed plate, driven shaft 14 is rotatably connected on the side wall of fixed plate 1, Gu
The through-hole passed through for driving member 15 is offered on fixed board 1, thread bush 16 is also rotatably arranged in fixed plate 1, passes through the snail of rotation
Bar 8 drives bevel gear set operation to drive driven shaft 14 to rotate, and driven shaft 14 drives thread bush 16 to rotate using driving member 15,
Thread bush 16 drives screw rod 17 to have the tendency that following rotation under threading force effect, but under the constraint of grip block 18, screw rod
17 only drive grip blocks 18 to slide up and down along 1 side wall of fixed plate, to clamp the outer wall of pipe fitting, realize at pipe fitting collar extension with
The clamping function of fixed plate 1；The bevel gear set includes the first bevel gear 12 being fixed on worm screw 8 and first bevel gear 12
The second bevel gear 13 for engaging and being fixed on 14 upper end of driven shaft drives first bevel gear 12 to rotate, to drive using worm screw 8
Second bevel gear 13 drives driven shaft 14 to rotate.
Embodiment 2
A kind of application method of the pre- apparatus for heat sealing with self-locking function, includes the following steps:
Step 1, adjustment, rotation regulating wheel drive worm screw reversion, drive tooth plate and sliding sleeve and sealing-plug retreat to backward most close to
Fixed plate side；
Sealing-plug is aligned at pipe fitting collar extension by step 2, inserting, is kept sealing-plug coaxial with pipe fitting, is rotated forward regulating wheel band
Moving tooth plate and sliding sleeve and sealing-plug protrude into pipe fitting；
Step 3, fixed, adjustment sealing-plug persistently promotes, until the outer wall of grip block and pipe fitting fits closely；
Step 4 checks, after grip block is bonded with pipe fitting outer wall, swings fixed column, checks and shake situation, be divided into following two
Kind:
Situation one, fixed column can not shake, and illustrate that grip block and the clamping of pipe fitting outer wall are firm, and sealing-plug and pipe fitting are coaxial；
Situation two, fixed column is unstable, illustrates that sealing-plug is not coaxial with pipe fitting, and it is same with pipe fitting to adjust it for sustained oscillation fixed column
Secondary fixation after axis.
According to the specific descriptions of above-described embodiment, being apparent from the working principle of the invention is: driving snail by rotation regulating wheel 9
Bar 8 rotates, and drives worm gear 10 to rotate by the worm screw 8 of rotation, so that gear 11 be driven to follow rotation, gear 11 is with moving tooth plate 7
It is slided with sliding sleeve 3 along guide rod 4, final to drive sealing-plug 2 mobile, realization stoppers the sealing of pipe fitting, since worm and gear passes
Dynamic to have the function of unidirectional self-lock, i.e., only worm screw 8 can drive worm gear 10 to rotate, and worm gear 10 can not drive worm screw 8 to rotate, because
This will not make sealing-plug 2 after rotation regulating wheel 9 is fixed by sealing-plug 2 expanding when pipe fitting is preheated
It steps down, there is self-locking function, drive bevel gear set operation to drive driven shaft 14 to rotate by the worm screw 8 of rotation, driven shaft
14 drive thread bush 16 to rotate using driving member 15, and the driving screw rod 17 under threading force effect of thread bush 16, which has, follows becoming for rotation
Gesture, but under the constraint of grip block 18, screw rod 17 only drives grip block 18 to slide up and down along 1 side wall of fixed plate, to press from both sides
It holds the outer wall of pipe fitting, realizes to, with the clamping function of fixed plate 1, worm screw 8 being utilized to drive 12 turns of first bevel gear at pipe fitting collar extension
It is dynamic, to drive second bevel gear 13 that driven shaft 14 is driven to rotate.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not limited only to above embodiments, and specific structure is allowed to vary.In every case in the protection model of independent claims of the present invention
Interior made various change is enclosed to be within the scope of the invention.
