[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 7 The present invention provides a technical solution for a pedal-type radiograph anti-accidental-touch mechanism of the foot pedal: a pedal-type radiograph anti-accidental-touch mechanism of the foot pedal, comprising a base plate 1, a box body mechanism, a pedal mechanism and a flip mechanism.

[0031] The bottom plate 1 is square in shape and is installed in a receiving groove opened on the ground.

[0032] The box body mechanism includes a square box body 2 sleeved on the outside of the pedal, the upper end and the right end of the box body 2 are open, and the lower side of the left end of the box body 2 is provided with a wire groove 21 for the pedal wire to pass through downwards, the lower end of the box body 2 is fixed on the bottom plate 1, and the upper left end of the box body 2 is hingedly connected with a right-angled cover plate 22, and the cover plate 22 is respectively attached to the upper end surface and the right end surface of the box body 2, and an elastic component is provided between the cover plate 22 and the box body 2, and the elastic component can make the cover plate 22 elastically press against the box body 2. The pedal is installed on the bottom plate 1 and is located in the box body 2. The wire extends to the left through the wire groove 21.

[0033] The elastic component is a rubber strip 23, and the upper end of the rubber strip 23 is fixed to the left side of the lower end of the cover plate 22, and the lower end of the rubber strip 23 is fixed to the upper side of the left wall of the inner cavity of the box body 2. The rubber strip 23, the cover plate 22, and the inner wall of the box body 2 form a triangle, and the cover plate 22 is elastically tightened. Note that the rubber strip 23 should not be too low to avoid affecting the inner pedal. There is an arc transition between the upper end and the right end of the box body 2, and the shape of the cover plate 22 corresponds to the box body 2. Reduce the edges and volume, because the pedal switch stepped on the right side is lower than the main part, so the arc transition is smaller. It also includes a shock-absorbing mechanism arranged between the box body 2 and the cover plate 22. The shock-absorbing mechanism can perform shock absorption and buffering when the cover plate 22 is covered on the box body 2 clockwise to reduce the sound when the cover plate 22 is closed. When the cover plate 22 is covered, under the action of the rubber strip 23, an impact will be generated, and the cover plate 22 will collide with the box body 2, which is easy to make a sound, which may affect the operation. Therefore, a shock-absorbing mechanism is added to reduce the sound generated by the impact. The shock absorbing mechanism includes a rubber strip 24 fixed to the upper and right ends of the box body 2 and a rubber pad 25 fixed to the bottom of the right end of the cover plate 22, and the rubber pad 25 is against the bottom plate 1. The rubber pad 25 is arranged along the end surface of the box body 2 that contacts the cover plate 22, so that when the cover plate 22 is closed, it can buffer and reduce shock to reduce impact and vibration, thereby reducing sound. The rubber pad 25 also plays a shock absorbing role and can be tough to contact the bottom plate 1 to prevent the lower end of the cover plate 22 from hitting the bottom plate 1 when the rubber strip 24 is compressed. In this way, the rubber pad 25 will be compressed to provide buffering and prevent the bottom gap from appearing.

[0034] The pedal mechanism is located on one side of the box body 2, and the pedal mechanism is located on the side where the doctor performs the operation. When the pedal mechanism is stepped on, it can move downward to realize elastic contraction. The pedal mechanism includes a square shell-shaped pedal 3 with an open lower end, and a matching support block 31 is inserted into the pedal 3. The lower end of the support block 31 is fixed on the bottom plate 1, and there is a contraction distance between the lower end of the pedal 3 and the bottom plate 1 for downward movement. Springs 32 are evenly arranged between the upper end of the support block 31 and the top wall of the inner cavity of the pedal 3. When the pedal 3 moves downward along the support block 31, the spring 32 can be compressed. When the doctor performs surgery, he will stand on the side of the footrest to turn on the switch. The pedal 3 is located in the area where the doctor stands, so that the doctor can step directly on the pedal 3. In order to lower the height of the pedal 3, a receiving groove is provided on the ground to place the bottom plate 1. The distance from the lower end of the pedal 3 to the bottom plate 1 can be set to 1 cm, and the distance from the upper end of the pedal 3 to the ground can also be set to 1 cm. In this way, when stepping on, the pedal 3 drops 1 cm and is just flush with the ground. The doctor does not feel awkward when standing on it. Moreover, the size of the pedal 3 can be made larger, so that the doctor can move back and forth on it. Only when the doctor walks away completely, the cover plate 22 is closed. When the doctor walks away from the pedal 3, the pedal 3 returns to its original position under the action of the spring 32.

[0035] The flipping mechanism is connected between the treading mechanism and the left end of the cover plate 22, and when the treading mechanism is retracted downward, it can drive the cover plate 22 to flip counterclockwise to open the box body 2. The flipping mechanism includes a pull plate 4 fixed to the left side of the lower left end of the pedal 3, and the pull plate 4 is sleeved on the box body 2. The pull plate 4 is provided with a guide groove 41 corresponding to the box body 2, and a gap is left between the right wall of the inner cavity of the guide groove 41 and the right end of the cover plate 22 for flipping the cover plate 22. It also includes a pull block 42 formed by the cover plate 22 extending to the left, and the left end of the pull block 42 is connected to the pull plate 4 through a downward pull rope 43, and the lower end of the pull rope 43 is inclined to the lower right to drive the cover plate 22 to flip counterclockwise. The pedal 3 is stepped down and moves, driving the pull plate 4 to move downward, thereby pulling the pull rope 43, which can be a nylon rope or a steel wire rope. The pull rope 43 pulls the pull block 42, thereby driving the cover plate 22 to rotate counterclockwise around the box body 2. The cover plate 22 is hingedly connected to the left side of the upper end of the box body 2 through a pin, and rotates around the pin to open the cover plate 22 and flip the cover plate 22 ninety degrees. It should be noted that the lower end point of the pull rope 43 is located directly below or to the right of the pin, thereby ensuring that the cover plate 22 can be flipped more than ninety degrees. The pull plate 4 is integrally formed with the pedal 3, and there is an arc transition between the pull plate 4 and the pedal 3. This is stronger and not easy to break. The bottom plate 1, the box body 2, the cover plate 22, the pedal 3, the support block 31 and the pull plate 4 are all made of transparent acrylic plate. It is light in weight, high in strength, easy to manufacture, and transparent, which is also convenient for observing the internal situation. The inner wall thickness of the bottom plate 1, the box body 2 and the pedal 3 can be set to 1.5 mm.

[0036] Here, the size of the box body 2 can be set to 25 cm in width, 30 cm in length, and 22 cm in height; the pedal 3 is larger so that the doctor can move around on it. The size of the movable pedal 3 can be set to: the width is greater than 60 cm, and the width is greater than 60 cm;

[0037] It should be noted that the left and right length of the pull block 42 can be set to 1 cm, and its left and right length should be greater than or equal to the height of the pedal 3 when it is compressed, so as to prevent the pedal 3 from continuing to move downward and breaking the pull rope 43. In this way, it can be ensured that when the pedal 3 is stepped on to the bottom, the pull block 42 is vertical, or has not reached vertical, so it will not be broken;

[0038] The above dimensions are for reference only. In practice, different size series can be set because the size of the pedal is not fixed. The purpose of the size is that the box body 2 can accommodate the pedal, the left and right lengths of the pull block 42 are greater than or equal to the height of the pedal 3. The size of the guide groove 41 is mainly based on not affecting the flipping of the cover 22, and the pedal 3 can be appropriately larger to facilitate the doctor's movement.

[0039] Working principle: When the doctor is working, he will stand in front of the foot pedal to turn on the switch and perform angiography. At this time, he will stand on the pedal 3 and can move on the pedal 3 to perform surgery. After standing on the pedal 3, the pedal 3 moves down along the support block 31 to compress the spring 32. Then the lower end of the pedal 3 rests on the bottom plate 1, and the pedal 3 drives the pull plate 4 to move down. The pull plate 4 pulls the pull rope 43, thereby pulling the pull block 42 and the cover plate 22. The cover plate 22 rotates around the pin shaft on the box body 2 to overcome the elastic force of the rubber strip 23, thereby opening the cover plate 22 and turning the cover plate 22 ninety degrees or more to expose the switch of the foot pedal. In this way, the switch can be stepped on at any time to perform angiography. The doctor can also move on the pedal 3 to facilitate surgery. It is very convenient to open it in this way. The doctor can stand directly on the pedal 3 without opening it specially. After the operation is over, the doctor leaves the pedal 3, and the pedal 3 returns to its original position under the action of the spring 32, and the pull rope 43 returns to its original position. At the same time, under the action of the rubber strip 23, the cover 22 flips back to its original position and covers the box body 2, thus avoiding accidental touch. When cleaning or moving around, the box body 2 will not be opened without stepping on the pedal 3, which is safer. When the cover 22 is closed, the rubber strip 24 plays a shock-absorbing role, reducing the vibration and sound when closing.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
