Description

Technical Field

[0001] The utility model relates to the field of rolling pins, in particular to a detachable and assembled rolling pin. Background Art

[0002] A rolling pin is a cooking tool in a cylindrical shape. It is used to roll on a flat surface, squeeze dough and other plastic food ingredients, and use it to twist and press dough until it is thin. It is an indispensable tool for making noodles, dumpling skins, wonton skins, and flatbreads. Traditional combined rolling pins connect the long-section rolling pin and the short-section rolling pin through threads. The threaded connection method requires the long-section rolling pin and the short-section rolling pin to be rotated in opposite directions and tightened to ensure a firm connection. Since the rolling pin is cylindrical and has a smooth surface, it is not easy to connect and disassemble through threads. Secondly, the connecting end of the rolling pin has threads, which can easily rub against the palm, making it inconvenient to use, and flour will stick to the threads and make it inconvenient to clean.

[0003] In order to solve the above problems, we propose a detachable combined rolling pin to improve the deficiencies of the prior art. Utility Model Content

A through groove 11 is provided at the center of the section rolling pin 2, which runs through both ends. An inner plate 2 12 is fixed on the inner wall of the through groove 11, and a movable guide rod 2 13 is inserted on the inner plate 2 12. A connecting block 14 and a sealing disk 15 are respectively fixed at both ends of the guide rod 2 13. Card grooves 17 corresponding to the limiting steel balls 6 are provided on the four surfaces of the connecting block 14, forming an overall detachable and assembled rolling pin structure, which adopts a plug-in connection instead of a threaded connection, is convenient for quick disassembly and assembly, and is also convenient for the long-section rolling pin and the short-section rolling pin to be used separately.

[0020] In this embodiment, a spring 2 10 is also sleeved on the guide rod 1 8, one end of the spring 2 10 is fixed on the inner plate 1 7, and the other end of the spring 2 10 is fixed to the end plate at the inner end of the guide rod 1 8. After disassembly, the sealing block 9 can seal the port of the end groove 3 to keep the end surface of the long section rolling pin 1 flat for easy use.

[0021] In this embodiment, a spring three 16 is also sleeved on the guide rod two 13, and the two ends of the spring three 16 are respectively fixed on the inner plate two 12 and the sealing disk 15. After being disassembled, the end surface of the short section rolling pin 2 can be kept flat for easy use.

[0022] In this embodiment, the top of the limiting steel ball 6 extends into the end groove 3. When plugging in, it is ensured that the limiting steel ball 6 can be squeezed into the slot 17, thereby limiting and fixing the connecting block 14, which is conducive to rapid assembly.

[0023] In this embodiment, the sealing block 9 seals the port of the end groove 3 , and the connecting block 14 and the sealing plate 15 seal the ports at both ends of the through groove 11 respectively, so as to prevent flour from entering the through groove 11 .

[0024] The principles and advantages of this utility model: Figure 1As shown, when the long-section rolling pin 1 and the short-section rolling pin 2 are plugged and assembled, hold the long-section rolling pin 1 upright with one hand and hold the short-section rolling pin 2 with the other hand, press the sealing disk 15 inward with the thumb to make it recessed into the through groove 11, and the spring three 16 is compressed, and the connecting block 14 extends out of the through groove 11, and then the connecting block 14 is inserted into the end groove 3, and the connecting block 14 squeezes the sealing block 9 toward the inside of the end groove 3, and the spring two 10 is extended, so that the spring one 5 pushes the limiting steel ball 6 into the card groove 17, so that the long-section rolling pin 1 and the short-section rolling pin 2 can be seamlessly and firmly connected, and the assembled rolling pin can be held in hand to twist and press the dough. When the long-section rolling pin 1 and the short-section rolling pin 2 are separated, as shown in FIG. Figure 2 As shown, hold the long-section rolling pin 1 and the short-section rolling pin 2 with both hands respectively, pull the long-section rolling pin 1 and the short-section rolling pin 2 in opposite directions, and the limiting steel ball 6 will shrink into the inner groove 4 after being squeezed, so that the connecting block 14 can be pulled out from the end groove 3, and the spring 2 10 pushes the sealing block 9 to reset, and the port of the end groove 3 is sealed. The spring 3 16 pulls the guide rod 2 13 to reset, and the connecting block 14 and the sealing plate 15 respectively seal the ports at both ends of the through groove 11, so that the ends of the long-section rolling pin 1 and the short-section rolling pin 2 remain flat and will not rub the palm, which is helpful for holding the two for separate use, and at the same time, it can also prevent flour from entering the end groove 3 and the through groove 11.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
