Description

Folding trolley with semi-automatic unfolding, folding by means of one button with folding attachments, spring pusher, tool key and the function of constructing container-type structures by the trolley.

Single-axle trolley on wheels, folds and unfolds telescopically semi-automatically by means of springs.

It combines the following functions: Trolley, mechanical shovel, stool, lift, mechanically driven trolley, snow collector and tipper, screwdriver, spring pusher, tool wrench, and as a supporting beam of a container type structure.

The invention relates to devices that are convenient for transportation of goods and small-sized in storage. The trolley is uniaxial, basically consists of a central bearing axis telescopically changing its length, in the interior of which a shaft rotating around its axis telescopically changes its length simultaneously with the bearing axis and with the bearing bridge, a shelf for cargo connected by rails by means of hinges, with a semi-automatic folding device and unfolding by means of one button, the ability to carry out by means of attachments: unscrew the tool wrench, tighten the nuts, screws

Folding trolley on wheels working position FIG. 1, shows the movement of unfolding into the working position of FIG. 2 wearable.

The semi-automatic method of unfolding and folding the cart from the folded state of FIG. 9 „into the working position of FIG. 8, 10, 5 by means of the axis 1,1.1 of the lift 23, inserts 14 and pivotally connected rails 2, 2.1, 3 and 8 connecting them.

It is carried out using one button 77 of FIG. 12 When the mechanism is cocked, that is, when the tension springs are stretched, they are ready to unfold, fold the cart with their own effort.

First press unfolding.

Second press folding. By first pressing button 77 of FIG. 12 by the latch 82 by means of the swing 79 (downward movement by pressing the finger on the button) the latch releases the rod 63 which unfolds the trolley into the working position i.e. extends the axis 1.1. relative to axis 1 and shelf 3 by means of cable 30.

At the same time, the retainer 75 imparts a force to the rod 64 by means of the tension spring 65, which is needed to fold the shelf 3 parallel to the axis 1 of FIG. 9 The cables 81 are also stretched before and after the button 77 at a certain distance (which is fixed by an emphasis or limiter).

In order to press the button 77 a second time on the cables 81 thereby releasing the rod 64 for folding with the cable 35 and at the same time releasing the lock 70 of FIG. 8 so that axis 1 slides in axis 1.1 i.e. formed.

For the subsequent charging of the spring mechanism necessary for repeating the folding, unfolding mode.

We pull the cable 72 until it folds the trolley, after which it cocks the mechanism, I stretch the spring 80 until the stop 67 is located at an angle (slope) of 3-17 degrees, necessary to pull the rod 63 to the left and fix it with a retainer 69 to the tension spring 74, along by means of a hitch 68 to further pull the rod 63 to the right, gaining the force of the spring 74 for subsequent unfolding and folding using the button 77 with the first and second pressing.

Those. the force of the cable 72 of FIG. 12 to the hitch 68 to the latch 69 pushes the rod 63 to the left. after hitching, as the spring 80 and the stop 67 will allow, it will go under the rod 63 and does not interfere with moving to the right, until it is fixed with the lock 82 for subsequent unfolding and folding, etc.

The cable 78 can be charged by pressing the axis 1.1. downward, which slides in the axle 1. The rod 63, after pressing the button 77 again, descends to the bottom under its own weight or the force of the spring 76 attached to the cable 73 of FIG. 12. Cable 41 runs on rollers 71.

The spring 74 is limited by the stop 62, overpowers the spring 65 and other springs, the force is adjusted at the production. for stretching a certain distance necessary for the mechanism to operate.

This semi-automatic method of unfolding and folding the cart from the folded state of FIG. 3 to the operating position of FIG. 1 is located in the inner cavity of the axis 1,1.1 or from the outside, instead of tension springs, compression springs can be used, instead of rods for a smaller size, pipes of different diameters can be used, which are fitted one and the other, which does not change the essence of the spring device itself.

The function of the shovel is carried out as follows: from the top on the shaft in the form of a hex, we put a nutrunner or attach it to the handle 5, from the bottom where the nozzle 14 is inserted, similarly to the shovel of Fig. 10 After putting on one wheel we make money with our foot on the carrier bridge 2, the cart stands on 2 wheels and the shovel is stuck into the ground, we press the wrench button, the digging process is in progress, or drive the cart with two wheels on the ground by pressing the harrow wrench button.

The function of the hoist, collector and tipper of snow, loose, solid loads is carried out as follows: We attach a cable 30 to the nutrunner of the upper part, which raises and releases the hoist 23 of FIG. 10 When the lift is raised, the frame is simultaneously extended, which is connected by a cable 30 to the insert 14 of FIG. 10, having reached a certain height (which is regulated by the length of the cable, screwed to the insert), the blade 47 is attached with a cable 30.2 and a tension spring 34 to the wall of the shelf 3, i.e. the end of the shelf, begins to overturn cargo, snow, etc. Due to the springs, the return mechanism of FIG. 10 Ie by raising the lift 23 to the top, we simultaneously extend and overturn what we need. Instead of a wrench, you can use the force of the legs or hands, by pressing on the cable 30 or the chain, or a belt with a relief for gears, such as a closed toothed belt, going from the upper mount 13 along rollers of the type connected at both ends of the bicycle chain through the roller at 14 in FIG. 10 from top to bottom, the chain has steps 5.1 of FIG. 10 for ease of pressing naked or by hand, the chain moves like a ratchet like screwdrivers, giving movement only in one direction when lifting 23, where the spring cone-shaped lock did not allow the chain to move downward, when the ratchet is adjusted in position, by pressing the button we remove the cone with chain, then the lift is lowered by free running, lowers under its own weight or due to the springs 34 attached to the insert 14 of FIG. 10, release the button, the movement goes backwards, etc. you can raise people, work.

Change the angle of the blade 47 regardless of the frame 54, for prying bulk goods due to the button, the lever by 5, since the force for the button is transmitted through the cable inside the flexible and rigid hose, the tube, this makes it possible to transfer the force regardless of the distance between the moving details. Manufacturing, operation, when the frame 54 with the insert 54.2 is bent due to the hinge with a sprocket 54.3 or a gear for a chain or a closed toothed belt, with stops 54.1 that limit the full exit of the frame 54 from the inner cavity of the shelf 3 and a spring lock with an asterisk or a gear, which when the approach of 2 limiters 54.1 due to the extension 54, removes the fixed fixation i.e. can rotate, with 47.1 which served as a hook for the chain, giving the movement of the frame 54 in the inner cavity 3 to the right, to the left. After the fixation from 47.1 is removed, the sprocket 47.1, due to the retainer springs, is pressed with the chain to 54.3 and begins to rotate, bend at the desired angles frame 54 perpendicular to 3, with the same drive force that moved the frame 54 in the inner cavity 3 to the right, to the left t .e. at the beginning, the frame is telescopically extended like a crane, then by the same mechanical drive as an excavator with a blade - a bucket 47, which is driven by a sprocket drive by means of a chain located in a telescopically extended pipe, or a rack attached to the chain of FIG. 10. The latch 47.1, when the latch is removed, that is, the approach of 54.1 begins to rotate and simultaneously presses 86 to 54.3 and rotates it, and together with it, 54 from 47 FIG. 10. Such a position of convergence 54.1 at 3 and 54.1 at 54.2, the desired rotation, bending 54, is fixed with a spring clip ie. 54.2 in the inner cavity 3, the fixation is removed by pulling the cable. The cables, chain 86, or the toothed belt move, run inside the U-shaped channel parallel 3 in 3, additionally serve for rigidity and as guides.

The shelf 3 is pivotally bent relative to the axis 1 and 1.1, in the same way the lifting 23, the extension of 54 and 47 can be carried out by separate drives, mechanical, manual, as by means of cables or screws.

The chain is passed approximately in the middle of 1/2 through a tube with the size of 1-2 cells 86 and attached to 34, this is to ensure the coupling of the drive when the parts of type 54 are pulled out. The shelf 3 can be attached from the side 1.

The blade or bucket 47 maintains its angle in accordance with the angle of raising or lowering 54 and 3, so that the load does not fall out.

Retractable, moving in guides parts of types 1.1, 1.2, 23, 54 and other similar moving parts by a cable or a closed toothed belt, driven manually or mechanically. On the cables we place a pusher in the form of a cone, triangle, square, when the cable moves to the left, the pusher removes the fixation from the spring retainer - the hook of the square type for the chain from the toothed rack located on one of the retractable parts of type 1.1, 1.2, 23, 54, on the other profile rack-type strip 7.5 of FIG. 10, the part pulled out by the cable begins to move to the left, when the cable breaks, the extended part retains its position fixed by a spring lock - a hook, also to the right, and in vertical directions, like a ratchet like screwdrivers, giving movement only in one direction when switching the ratchet change direction, i.e. spring clip 7.4 of FIG. 10 allows the sliding parts to move only in one direction, pressing 7.3, if we remove the fixation from it due to the pusher 7.2 which is pushed by the projections on the springs 7.3 located on one of the sides of the chain 86 fixation 7.4 the sliding part is removed can move in the other direction, the chain 86 together with this carries out mechanical or manual extension of parts of the extendable type 1.1, 1.2, 23, 54, the pusher 7.2 moves while it releases the fixation from 7.4 in the guides at an angle similar to 50, as it jumps off one ledge to another, the pusher has a return spring like 7.4 their number set according to need. Such 7.4 with 7.2 and 7.3 are installed on two and n - the number of sides of the extendable frames of type 54, movement to the right projections 7.3 are pressed by the pusher 7.2 at the same time the projections on the other side 86 push 7.2 by removing the fixation, so that movement to the right is free, the movement to the left is similar, and in two vertical directions, or by means 74.1 of FIG. ten.

Bearing axle 1 and with 1.1, 1.2 or several axles rotate jointly around due to hinges at the base of the bearing bridge.

The dump contains an insert 25.1 - retractable flexible from the bottom of the dump 47, extends, slides into rounded, oval-shaped guides located on the sides of the dump, such as a sliding door of lockers only due to bending, slides into the inside of the cabinet, if necessary, insert 25.1 of FIG. 10 can be removed.

The trolley with a mechanical drive is carried out as follows: We attach the third wheel to the bearing axle, the axle of which has a hexagon using a flexible adapter for a nutrunner screw, we connect it to the shaft 61, and by pressing the button of the nutrunner which is located on top and attached by means of a hexagonal attachment to the shaft 7. For convenience on 2 in the place of the hinge joint 8 to 2.1 we place the plate at an angle, so that the end 8 along it smoothly along the circumference, unfolds the shelf 3. Fig. 8

Extending the bearing bridge with wheels 2 and the luggage rack 3 of FIG. 1 from the inner cavity of the bearing axis 1 occurs due to the movement of one of the telescopically connected parts of the bearing axis 1 and 1.1 of FIG. 1, 2, 3, namely, the smaller diameter 1.1 at the end of which the cone on the spring 18 of FIG. 2 begins to move apart the bearing axle with 2 wheels. on the right and on the left, and a shelf 3 for the carriage of goods and luggage, which is hinged to the fastening module, by a rail 2.1 from a vertical to a horizontal position. Spring cone 18 of FIG. 2 expands the carrier bridge 2 of FIG. 2 if the parts of the bearing bridge are pivotally connected together, on the same plane, the line of the cone can stand diagonally. With the completed unfolding of the bearing bridge from the hole 9 of FIG. 1 to the operating position of FIG. 2, the cone is clamped by a spring, when folded, the spring is pushed back, etc. The shelves 3 from the opening 10 of FIG. 1 are folded out due to the cone 4 of FIG. 2 which can also be on a spring, located at the end of the wall of the bearing axis 1.1 of FIG. 2.

Cone 18 and 4 of FIG. 1, 2 can be combined into one cone with the configuration and performance of both cones.

The fastening module of FIG. 2 is a part on which the shelves 3 are hinged and the bearing bridge 2 is located in the inner plane of the axis 1. The bearing bridge and the shelves are in the horizontal, i.e. in the working position are rigidly fixed by the lower end of the bearing axle 1.1 with a protrusion 7.1 for rigidity and supporting parts of the angular shape 16 of FIG. 1. The shelves 3 and the bearing bridge 2 of FIG. 1 are connected by springs of tension, compression or torsion to return to a vertical position in the inner cavity of the bearing axis 1, not protruding outward. Or with a cable with tension springs, an elastic band, attached to the lower part of the end of the axis 1.1, which, when folded, pulls the shelves 3 and the bearing bridge 2 into the inner cavity of the axis 1.

The shelves are moved apart in a v-shape in a horizontal position due to the triangle located in the lower part of the fastening module 12 of FIG. 1 fit snugly in the grooves, and are fixed by the axis 1.1 of FIG. 1.2. There can be more than two shelves connected by cables or rubber bands.

To adjust the angle of the shelves to the axes 1 and 1.1, we use the plate 20 of FIG. 2, 3 with a hole for a screw, which changes the height and fixes the plate, and the shelf 3 of FIG. 2. Or by screw 19 of FIG. We change the height of the attachment module located in cavity 1.

In the same way, ladders can be arranged by extending the shelf and the bearing bridge at different heights and quantities. From the outer surface of the axis 1, 1.1 from the side of the shelves 3 at a certain height, there is a fastener for which it is possible to fasten bags, bags, suitcases by the handles, and on the upper surface of the shelves there are protrusions 24 of FIG. 1,2 which help to keep packages, suitcases, bags, so that they do not slide off the shelves. And on the upper surface of the shelves are and are attached thin plates of magnets, and the lower part of packages, bags, flexible plates of metal or plastic with magnetizing properties, this is necessary to fix the load, goods.

The cart is brought to the working position by pressing the axis 1.1. fig. 1, 3 to the bottom, manually, or by pushing the lock 70, which loosens the tension or compression spring that pulls the axis 1.1. down to the fastening module and releases from the inner cavity of the axis 1 the shelf and the supporting bridge suitable for transporting goods and goods. Bring the trolley to the working position with the following way - the expansion of the axis 1.1 from 1 in different directions, this is when the cable 30 is attached on one side to the axis 1.1 on the other, passing through the roller 29 located on the fastening module 21 of Fig. 2, to insert 29.1 from the bottom, as a result, when we pull out the axis 1.1 from the inner cavity of axis 1, insert 29.1 with the combined cones 18 and 4 located on it, brings it out of the internal cavity of axis 1, carrying bridge 2 and shelf 3 from a vertical to a horizontal position those. into the operating position of FIG. 1, 2, 3. and is fixed with a spring button the catch 70.

It is folded by pressing 70, due to the tension spring 34 with a cable attached to 21 on the other side is attached to the axis 1.1., A similar spring 34 with a cable on one side attached to 1.2, on the other to the axis 1.1, which, reaching the stop that stops folding, with a spring 34 raises 1.2 frees up space for folding 2 and 3 inside the axle 1. When folding, the removal of the wheels 7 can be inserted and back into the spring-fixed grooves on the axle 2, or screwed into the threaded hole.

It is also possible to fold, unfold the shelves 3 and the bearing bridge 2 from the outside, vertically, adjacent parallel to the bearing axis 1.1 of FIG. 3 to place the shelves 3 and the bearing bridge with wheels 2, with the fastening module 21 of FIG. 2 located in an axis with a size of 1.1 and pressing from above with axis 1, bring the shelves and 3 and bridge 2 into working position, i.e. in the horizontal position needed for the transportation of the cargo fig. 1, 2, 3, for the rigidity and strength of this position, we place expanding inserts 7.1 of FIG. 3 in places where 2 and 3 are folded, unfold, this end of the axis 1 can have a slope of a certain angle of FIG. 3, which helps shelf 3 and bridge 2 with the same slope, to take a working position. The hinge joint 2 and 3 on the attachment modules or pivots 1.1 enters the inner cavity of the pivot 1.1 at a certain depth, convenient for the rotational movement of these hinges and the space occupied when folding vertically. The reverse vertical position of the shelves 3 and 2, is taken due to the torsion spring at the hinge points, or the tension spring with the cable 30 coming out from the inside of the vertical hole 9.1, inside the axis 1.1 attached together with the axis 1 to the compression spring 34.1, due to this, the shelf 3 and the bearing bridge 2 take a folded upright position, and also by means of a lock button 70 folds and unfolds or a duplicate button 77. FIG. 12. A spring retainer similar to the retainer 69 of FIG. 12 fixing the hitch on the sides of the axis 1.1 and from above 1 pressing 2 and 3 in the working position of Fig. 3. As already mentioned, the button 70 that releases this fixation can be located in different places, since the force for the button is transmitted through the cable inside the flexible and rigid hose , the tube, this makes it possible to transfer force, regardless of the length of the folding, folding telescopic axes 1, 1.1 and 1.2, i.e. the cable moves inside the tube, abutting on the ends on both sides, return due to springs, or simply pull the cable from the retainer.

When transporting and adjusting the height 17 of FIG. 3, we use the third part of the telescopic folding axis 1.2, which can enter the axis 1.1 or overlap with it FIG. The number of axles can be changed according to the needs of the manufacturer. In order to avoid detachment of the axis 1 from 1.1, 1.2, we use a type 28 lock in Fig. 3 on both sides only instead of hole 11, a recess, or a hole in the form of a groove for the passage of a pin, a screw fixed on the plane of the other axis.

Wheels 7 with a built-in oversized screw can be screwed into a threaded hole at the ends of the bearing axle. fig. 3 and pivotally folded parallel to 2 and 1, when unfolded perpendicular to the supporting bridge of FIG. 3.

The function of bending the axes 1 and 1.1 is carried out by plates 25 in the amount of 2 pieces, a hinge 17, a frame 22 the size of the inner cavity of the axis 1, so that it can go in it, and a spring clip 28 inserted into hole 11 in FIG. 3. The plate 25 on one side is permanently attached to the axis 1.1, the other freely walks with the frame 22 inside the axis 1 until the moment, if necessary, when the spring lock 28 with an expansion in the form of a cone, a triangle with a protrusion for fixing the wall of the axis 1 falls into the hole 11, use frame 22 so that the plate is tightly pressed.

Thereafter, the axes 1 and 1 are of different sizes and can be articulated at different angles.

The hinge joints can also be formed by inserting the end of the bearing bridge 2 into the inner cavity of the handle 5 of FIG. 4 round handle can be of other shape. Plates 25 with hinges 17 can be attached to the outside of the axles 1, 1.1. With such a construction, like a designer, it is possible to create articulated folding bearing beams with a rectangular base, FIG. 5 thus form container-type structures. With the base top and bottom, with the right and left beams, they are the same side beams, front and rear, they are the end beams. These beams are axes 1 and 1.1 of FIG. 4, 5. connected to each other, where it is rigidly fixed, where the hinge required for folding the given structure like the accordion of FIG. 4.5. This structure, consisting of hingedly connected beams of the container type, the beams are sheathed with profile decking made of aluminum, steel, honeycomb and monolithic polycarbonate as a greenhouse, so that the beams can be folded like an accordion in Fig. 4, 5 .. Can be folded, unfold by means of springs and cables. It is arranged like this, the base is rectangular and the ceiling is the same, along the perimeter on the right and left, the bearing beams are pivotally connected to the base and the top, and in the middle they are pivotally bent like an accordion. The cables 30 for unfolding are attached from the inner side of the axle 1.1 approximately in the middle, then along the rollers 29 through the insert-lever for unfolding 32 FIG. 4 are connected to the tension spring 34, which is attached in the middle of the axis 1. Also, the cable 30 can be connected through the beam 1 to the fastener 36 and further along the rollers 29, due to the insert - the lever for unfolding 39. This allows the right and left beams to raise the ceiling from the accordion-folded fig. 4.5

So that, when unfolding, folding the structure, alternation occurs, i.e. at the beginning the right and left beams are laid out, then the front and rear beams 42 of Fig. 5 due to the movement in one direction with one cable 35 connected by the front and rear beams by a connector 40, a tension spring 34, a stop 41 which abuts against a ring 38 connected by cables with the right and left beams and folds them like an accordion, after initially folding the beams 42 into the cavity of the base 89, on top of these cables in FIG. 5., the right and left beams are pivotally connected to the base just above the beams 42 of FIG. 5 is thus folded, also by alternating folding of the beams by means of 34,38,40, 41, at the beginning the end beams, then the side beams with the skin. It is unfolded by means of a cable 30 attached to the shaft, manual or automatic drive, or tension springs, it is possible with torsion springs used in the hinge joints of the beams. The drive shaft pulling the cables 30 and 35 of FIG. 4 or only the cable 35 for folding, if unfolding was carried out by tension or torsion springs, it can be driven by a motor or by manual rotation, like a ratchet like screwdrivers, giving a twisting force only in one direction, in the other there is free movement. Instead of a cable at the drive, a chain can be used. When the button is pressed, which removes the fixation of the shaft giving a twisting force only in one direction, and not allowing it to unwind in the other direction, the structure under the action of the tension or torsion springs of FIG. 4.5 starts to unfold. Cable 35 of FIG. 5, when folded, simultaneously releases the lock from the lock 43 which fixes in the vertical position the beams 42 with the ceiling of FIG. 5 with insert 39 of FIG. 4, at the side beams, the cable 35 is attached from the outer side of the axis 1.1, the same beam, approximately in the middle, then along the rollers of the insert - the lever 33 of FIG. 4 for folding, passing along the rollers 29 through the axis 1, and coming out from the inner side of the axis 1 to a height of about 1/3 - 1/5 from the base, or and the rollers in it creates an angle with a cable 35 giving force for folding the right and left beams, after folding and unfolding, the tension spring 34 in the base cavity returns the cable 35 to a vertical position parallel to the inner surface of the beam of FIG. 4, the cable runs freely in the spring 34. The insert 39 of FIG. 4.5 does not protrude, if necessary, it can protrude beyond the lateral perimeter of a vertically expandable beam 1 with an outer skin, both end and side beams, similarly with the insert 33 of Fig. 4.

In the same way, the structure of the square type can be folded, unfolded, sheathed with telescopically folding plates in the planes in height and width, i.e. X and Z. together with supporting beams 1 and 1.1 in three planes X, Y and Z. X - right and left, Y - forward and backward, Z - top and bottom. When folded, it decreases in volume from each of the X, Y and Z planes, by a size of 30% or another required size for this, with the same device sequentially folding the beams and plates as in Fig. 5. Inside the bearing axles of the folding beams are located 34.1.

For quick unfolding of a container, square or similar structure, we use the L-shaped lever 45 of FIG. 5 of a round or square profile, which is freely inserted into the hole of the same profiles on the outer side of the axis1 over the skin, and by pressing from the top down to the opposite end of the lever, as a result, the right and left beams change their position from horizontal to vertical. The lever is pivotally connected, folds, parallel to the base, in working condition perpendicular to unfolding the structure. From the outside, from the inside, in places of fold in a container-type structure, a fabric, tarpaulin is attached, for wind-moisture, heat protection.

Further, by cable 44 of FIG. 5 on one side attached to the ends on the side of the retainer 43 of FIG. 5 of the front and rear beams 42 of FIG. 5 along the rollers through the middle of the ceiling, which is already raised by the L-shaped lever, goes outside the structure. We pull the cable 44 from the top down and the front, rear beams 42 take a vertical position with a fixation, a lock 43. The structure has taken a ready working position of the container type, i.e. unfolded.

To fold, pull from the outside another cable similar to 44 in FIG. 5 on rollers through the middle of the ceiling, which on the other side is connected to the retainer 43, thereby removing the vertical fixation of the beams 42, when a certain angle of inclination of the beams 42 is reached, the structure folds like an accordion under its own weight, into a folded state for easy transportation.

The end and side beams of the base, due to the screw connection 70 of FIG. 4 can be detached on Vz and folded in this format, in a column from left to right.

Spring loaded pusher. Simultaneously with the structure, benches can be folded, unfolded, shelves consisting of 2 rails pivotally connected to each other, also pivotally connected to the base and to the right or left beams, the rail at the base is vertical, at the side beams, horizontal folds, folds like an accordion together with the structure container type. The number of rails, support beams, and other parts can vary depending on the size and load-bearing capacity. Also, in the inner cavity of the base 89 of a container-type structure, under the skin you can install foam, foam-flex, so that the structure formed by axes 1 and 1.1, they are supporting beams, remain afloat, transported on the roofs of cars, as well as several container-type structures can be connected to each other forming a new structure,

For strength, we use a pivotally folded rail from the end beams with a skin that is inserted into the hole of the side beams 1, 1.1 at the corners, or fastened with corners.

Spring loaded pusher. Carries out the function of movement of syringes 55, along the cylindrical pipe 15, inside the axes 1 and 1.1. By means of the cocking mechanism 48.50 on the return spring 34.1 of FIG. 6, Cocking is carried out due to the stop 50 located on the chain 46, moving along the sprockets 51 or gears, if instead of the chain there is a belt with teeth that form an angle with a slope of the amount required for cocking 48 of a certain force from 50, having reached which to lower the cocking 48 and back by movement 50 along the chain of FIG. 6. The syringes 55 can enter the tube 15 through the magazine 52, by means of the spring 34.1 or the tape with the syringes 57 of FIG. 7. Or by means 57, which is pushed, advances through 15, the pusher wheel 53, on the outer perimeter of which an angular pusher 56 is located, which moves 57 in a circular motion in a certain direction. This is due to the tension spring 34, the plate 60 attached from the axis 53 to its perimeter, and the angular bulges 58, when rotating 53, 60 and 58 meet and raise 53 from the outer plane 1.1, whereby 56 advances 57. Due to 34 FIG. ... 7 this is repeated back. The bulge 58, attached to the outer plane 1.1, is in the inner cavity 53 like 60 in FIG. 7 attached to 53 during rotation 53, 60 and 58 meet and raise 53, 57 begins to move. The strip 57 arriving at 15 passes through 92 circular knives with protruding angular cutting parts at the edge of the corner, then the teeth.

This assists in opening the package 55 and discarding through opening 93 of FIG. 7. Then the syringes stand at 15 at 71.3 and 71.4, which move and are adjusted by 59.1, 72.1 gears, through frames 71.1 and 71.2 they take the contents from 59.3, open at an angle 27, a wedge of a certain material attached next to the hole where the ampoules enter which due to movement ampoules similarly to 57, the ampoule is opened, then the cap is removed with 37, after the injections it is put back on, then 55 is discarded 71.2. After the injection, the surface, by injecting or throwing out the cotton wool treated with the agent, is necessary after the injection.
