Description

Technical Field

[0001] The invention relates to a kitchen utensil, in particular to a rolling pin which does not hurt hands. Background Art

[0002] Making dumplings requires rolling dough, especially for dumpling restaurants of all sizes, and northerners making frozen dumplings in winter, which requires rolling out a lot of dumpling skins continuously. The dough rolled out by hand with a rolling pin has a fiber texture formed on the surface after repeated rolling and pressing by the rolling pin, just like the effect of forging on metal materials. The dough is slightly thicker in the middle, not easy to break when cooking dumplings, and has a chewy and delicious taste when eating. It is deeply loved by people and cannot be compared with dough made by machines. However, when rolling dough with an existing rolling pin, the rolling pin contacts the palm in the form of a straight line on the surface, which also plays a role of repeatedly rolling and pressing the palm. Over time, the palm will be painful, red and swollen, and even traumatized to the palm, making it difficult to continue working. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the background technology and provide a rolling pin that can roll dough by hand and conforms to the traditional rolling method but does not hurt the hands, so that a large amount of dough rolling work can be completed more easily when making dumplings.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A rolling pin that does not hurt hands of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, it includes a panel 1, a slide groove 6, a fastening screw 7, a fixing frame 9, a rotating shaft 10, a rolling shaft 11, a bearing 12 and a handle device.

[0006] The panel 1 is a rectangular wooden board, and two fixing frames 9 are installed side by side on one side by fastening screws 7. The front end of the fixing frame 9 is provided with a slide groove 6, and the slide groove 6 is connected to the handle device through the internal bearing 12. The two ends of the handle device are movably connected and mounted on the rolling shaft 11. When the handle device is held by hand and a certain pressure is applied downward, and the handle device is moved forward and backward, the handle device drives the rolling shaft 11 to roll back and forth on the panel 1, so that the small dough for making dumplings prepared in advance can be rolled into dough.

[0007] The rolling shaft 11 is a hollow cylinder made of light metal material, with rotating shafts 10 at both ends;

[0008] The handle device is as follows Figure 2 and Figure 6 As shown, it includes a support plate 2, a horizontal plate 3, a handle 4, a connecting rod 5, a small shaft 8, and an elastic sheet 15;

[0009] The horizontal plate 3 and the supporting plate 2 are made of a light metal material with high strength. The horizontal plate 3 is a long fan-shaped plate, and the two ends are made into supporting plates 2 perpendicular to the horizontal plate 3. The lower end of the supporting plate 2 is made into a circular arc groove opening downward, and a pair of elastic sheets 15 are made at both ends of the opening of the circular arc groove.

[0010] The length of the rolling shaft 11 is slightly smaller than that of the horizontal plate 3. By gently pressing the rolling shaft 11, the rotating shafts 10 at both ends of the rolling shaft 11 can overcome the elastic force of the elastic sheet 15 and be pressed into the arc groove opened at the lower end of the supporting plate 2, and the rolling shaft 11 can rotate freely in the arc groove.

[0011] The handle 4 is made of food-grade rubber material, has an elliptical cross section, and is fixed at the middle position of the upper part of the horizontal plate 3 .

[0012] The supporting plate 2 has a connecting rod 5 on its rear side. The connecting rod 5 is a short rod with a rectangular cross section. The outer side of its rear end has a small shaft 8. The small shaft 8 is inserted into the circular hole of the inner ring of the bearing 12 to connect with the two slide grooves 6.

[0013] The chute 6 is as follows Figure 3 , Figure 4 , Figure 5 As shown, the overall shape is a rectangular parallelepiped and is made integrally with the fixing frame 9. A rectangular hole is opened on the inside of the rectangular parallelepiped. The bearing 12 is inserted into the rectangular hole from the right side of the rectangular hole. The left side and the front bottom of the rectangular hole are provided with protrusions 14 to prevent the bearing 12 from falling off. The upper and lower planes inside the rectangular hole are both tracks 13 for the bearing 12 to move when working.

[0014] Two clamping screws 7 are installed on the fixing frame 9 , and a rotatable clamping sheet 16 is installed at the lower end of the clamping screw 7 .

[0015] The bearing 12 is a needle bearing, the outer diameter of which is 0.3-0.5 mm smaller than the height of the rectangular hole in the slide groove 6 , and can move along the track 13 .

[0016] It can be seen from the technical solution provided by the present invention that the beneficial effects of the hand-free rolling pin described in the present invention are as follows: (1) When rolling dumpling skins with a traditional rolling pin, the palm of the hand is used to roll the dough skin. The rolling pin contacts the palm in the form of a straight line on the upper surface, which also plays a role of repeatedly rolling and pressing the palm. The palm will be painful, red and swollen after a while, and even cause trauma to the palm, making it difficult to continue working. In the present invention, it is changed to hold and press the rolling pin with the palm, and push the rolling pin back and forth to roll the dough skin. Since the surface of the handle 4 is an elliptical surface, the contact area with the palm is large, which is convenient for applying pressure to the rolling pin, and the palm will not be hurt during long-term work. It can adapt to a large number of long-term rolling work, greatly improving work efficiency. (2) The palm pushes the rolling pin back and forth, which is suitable for palm force and conforms to the traditional way of rolling noodles. Compared with the traditional rolling pin rolling dough skin, it can be operated without special training. The present invention is particularly suitable for dumpling restaurants and other catering industries and for making frozen dumplings in Northeast China. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings 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 protection scope of the present invention.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] A rolling pin that does not hurt hands of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, it includes a panel 1, a slide groove 6, a fastening screw 7, a fixing frame 9, a rotating shaft 10, a rolling shaft 11, a bearing 12 and a handle device.

[0027] The panel 1 is an ordinary rectangular wooden board. Two fixing frames 9 are installed in parallel on one side of the panel 1 by fastening screws 7. The distance between the two fixing frames 9 depends on the length of the handle device. The front end of the fixing frame 9 is provided with a slide groove 6. The slide groove 6 is connected to the handle device through an internal bearing 12. The two ends of the handle device are movably connected and mounted on the rolling shaft 11. When the handle device is held by hand and a certain pressure is applied downward, and the handle device is moved forward and backward, the handle device drives the rolling shaft 11 to roll back and forth on the panel 1, so that the small dough for making dumplings prepared in advance can be rolled into dough.

[0028] The rolling shaft 11 is a hollow cylinder, which is made of light metal material for easy carrying and flexible use, and has rotating shafts 10 at both ends; the handle device includes a supporting plate 2, a horizontal plate 3, a handle 4, a connecting rod 5, a small shaft 8, and an elastic sheet 15. The handle device is made of a light metal material with high strength as a whole, the horizontal plate 3 is a long fan-shaped plate, and the two ends are made of supporting plates 2 perpendicular to the horizontal plate 3, and the lower end of the supporting plate 2 is made into a circular arc groove opening downward, and a pair of elastic sheets 15 are made at both ends of the opening of the circular arc groove;

[0029] The length of the rolling shaft 11 is slightly smaller than the length of the horizontal plate 3. The elastic sheet 15 is aligned with the rotating shaft 10 at both ends of the rolling shaft 11 and lightly applies pressure, so that the rotating shaft 10 at both ends of the rolling shaft 11 can overcome the elastic force of the elastic sheet 15 and be pressed into the arc groove of the lower end opening of the support plate 2. After the spring sheet 15 returns to its original position, the rolling shaft 11 can rotate freely in the arc groove but will not fall out of the arc groove. The handle 4 is made of food-grade rubber material, has an elliptical cross-section, and is fixed at the middle position of the upper part of the horizontal plate 3. The handle 4 can be conveniently pressed by hand and moved back and forth to achieve the purpose of not hurting the hand. Because the device is in contact with flour, the food-grade rubber material can ensure food safety.

[0030] The supporting plate 2 has a connecting rod 5 on the rear side. The connecting rod 5 is a thin rod with a rectangular cross section. The outer side of the rear end has a small shaft 8. The small shaft 8 is inserted into the inner circle hole of the bearing 12 to connect with the slide 6. The slide 6 is a rectangular parallelepiped with a rectangular hole on the inside. The bearing 12 is inserted into the rectangular hole from the right side. The left side and the front bottom of the rectangular hole are both provided with protrusions 14 to prevent the bearing 12 from falling off. The upper and lower planes inside the rectangular hole are both tracks 13 for the bearing 12 to move when working. Two clamping screws 7 are installed on each fixing frame 9, and a rotatable clamping sheet 16 is installed at the lower end of the clamping screw 7.

[0031] The bearing 12 is a needle bearing, the outer diameter of which is 0.3-0.5 mm smaller than the height of the rectangular hole in the slide groove 6 , and can move along the track 13 .

[0032] Needle bearings are equipped with thin and long rollers, so the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, which is particularly suitable for bearings with limited radial installation dimensions. This solution uses Harbin bearing BK1210, which has an inner diameter of 12mm and an outer diameter of 16mm; a stamped outer ring, a closed tail end, and no seals. The small shaft 8 and its inner hole are clearance-matched, that is, the small shaft 8 can be inserted into the inner hole of the bearing at any time to work. Because it is used under extremely small force and extremely low speed conditions, it is sufficient to keep the bearing dry and no lubrication is required.

[0033] When using, Figure 1 As shown, first, insert the rotating shaft 10 at both ends of the rolling shaft 11 into the arc groove at the lower end of the supporting plate 2, and then put the bearing 12 into the rectangular hole from the right end of the rectangular hole inside the slide groove 6, and then insert the small shaft 8 on the outer side of the connecting rod 5 outward into the circular hole of the inner ring of the bearing 12 to connect it with the slide groove 6, and finally fix the fixing frame 9 to one side of the panel with the fastening screws 7. The slide groove 6 can generally fit the panel 1 (if there is a big difference, you can add or subtract wooden gaskets between the bottom of the panel and the fixing frame 9).

[0034] The method of use is the same as the traditional rolling pin. Press and move the handle device back and forth with one hand, and use the other hand to rotate the pre-made small dough to process the dumpling dough, which is exactly the same as the traditional hand-rolled dough.

[0035] When the handle device drives the rolling shaft 1 to roll back and forth, the small shaft 8 on the connecting rod 5 drives the bearing 12 to move in the rectangular hole in the slide groove 6. The bearing 12 is sometimes subjected to an upward force and sometimes subjected to a downward force. However, because the outer diameter of the bearing 12 is 0.3-0.5mm smaller than the height of the rectangular hole in the slide groove 6, the bearing 12 can move freely along the upper and lower planes of the track 13, and the bearing 12 can rotate normally to reduce the resistance to the forward and backward movement of the handle device and the rolling shaft, that is, it does not affect the work of the rolling shaft.

[0036] After use, the fixing frame 9 can be removed first, the small shaft 8 can be pulled out from the bearing 12, and then the rolling shaft can be pulled out from the arc groove of the supporting plate 2. If flour falls into the rectangular hole of the chute 6 and the bearing 12, it can be wiped clean and stored.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
