Description

Technical Field

[0001] The utility model relates to the technical field of hardware connectors, and particularly to the technical field of a plug pin assembly and a rotating mechanism of an emulsifying machine to which the plug pin assembly is applied. Background Art

[0002] When an emulsifying machine is working, the scraper is subjected to a shearing force, so the fixation of the scraper is particularly important. The scraper is usually fixed to the stirring paddle through a plug pin. Therefore, in order to stably fix the plug pin of the scraper, an open split pin that can be bent and unfolded is usually used. However, when the open split pin is applied to an emulsifying machine, it is not easy to disassemble and assemble. When using tools for disassembly and assembly, due to the small size of the open split pin, there is a risk of falling into the pot, which will damage the pot of the emulsifying machine.

[0003] In this regard, for example, the shaft pin for the rotating shaft of the power device in Chinese Patent CN203702796U discloses a new solution in which the pin shaft core is inserted into the pin hole of the rotating shaft, and the elastic retaining hoop bypasses the rotating shaft and its two ends are respectively connected to the two ends of the pin shaft core. However, the installation of this solution is actually also carried out inside the pot body. Although the installation convenience has been improved, the risk of falling into the pot still exists.

[0004] Therefore, the foreign object risk brought by the scraper fixing part in the emulsifying machine manufacturing industry has become a pain point that still needs to be improved in the industry. Summary of the Utility Model

[0005] In view of the above technical limitations, the utility model aims to design a plug pin assembly and a rotating mechanism of an emulsifying machine to which the plug pin assembly is applied, aiming to realize quick disassembly and assembly of the positioning pin of the emulsifying machine scraper without tools, and avoid damage to the pot body caused by the falling of this part.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A plug pin assembly includes a plug pin and a retaining pin. The plug pin includes a pin head and a rotating shaft. The pin head is provided with a positioning hole, and the lower end of the rotating shaft is provided with a first fixing hole and a second fixing hole at intervals;

[0008] The retaining pin is formed by bending an elastic plastic fixing strip. The elastic plastic fixing strip passes through the positioning hole, and a positioning part is formed by bending at the positioning hole, and the two ends extend outwards and then fold back to pass through the first fixing hole and the second fixing hole respectively;

[0009] The embedded sections of the elastic plastic fixing strip with the first fixing hole and the second fixing hole are provided with positioning grooves.

[0010] Compared with the prior art, in this case, an elastic and plastic fixing strip passes through the positioning hole and is bent to form a positioning part, which can prevent it from falling off during disassembly and assembly. At the same time, taking advantage of its elastic and plastic characteristics, it is bent back and passes through the fixing hole, and a positioning groove is arranged in the embedded section with the fixing hole, so that the bolt can firmly fix the stirring paddle of the emulsifying machine.

[0011] In a preferred embodiment, after the elastic and plastic fixing strip is bent to form a positioning part at the positioning hole, both ends extend outward in the opposite direction and then fold back to form elastic parts, ensuring that the elastic and plastic fixing strip is more stable during installation.

[0012] In some embodiments, a U-shaped deflection ring is formed at the reverse bending position of the elastic part.

[0013] In some embodiments, the positioning hole, the first fixing hole, and the second fixing hole are axially parallel in the same plane.

[0014] In a preferred embodiment, the elastic part is provided with an aligned bending section so that its end can be aligned with the first fixing hole or the second fixing hole.

[0015] In a preferred embodiment, the elastic and plastic fixing strip is spring stainless steel.

[0016] In a preferred embodiment, the width of the positioning part is 1.1 to 1.3 times the diameter of the pin head.

[0017] In a preferred embodiment, the width of the positioning groove is 1.2 to 1.5 times the diameter of the rotating shaft.

[0018] An emulsifying machine rotating mechanism includes the bolt assembly as described above, and further includes a scraper and a stirring paddle fixed by the bolt assembly.

[0019] In some embodiments, the scraper is provided with a group of protrusions through which the rotating shaft passes, and the stirring paddle is provided with a group of extension arms that extend between the group of protrusions and are passed through by the rotating shaft.

[0025] The features of the present utility model and other related features will be further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0026] Please refer to Figure 1 , in this embodiment, the plug component 100 of this case takes the application on the rotating mechanism of an emulsifying machine as an example. The emulsifying machine is provided with a scraper 200. Therefore, the plug component 100 also needs to consider the action of shear stress. Relatively speaking, there are relatively high requirements for the plug component 100 of the scraper 200 on the emulsifying machine. The application scenario of the plug component 100 of this case cannot be limited by the fact that the emulsifying machine is involved in the embodiment.

[0027] Please refer to in combination Figure 2 , the plug component 100 includes a plug 110 and a retaining pin 120. The plug 110 includes a pin head 111 and a rotating shaft 112. The scraper 200 has a set of protrusions 210, and there are through holes on the protrusions 210 through which the rotating shaft 120 passes. In this embodiment, for the convenience of description, the direction of the scraper 200 is described as the outside, and the opposite direction is provided with a stirring paddle 300, which is described as the inside. The stirring paddle 300 is provided with an extension arm 310 extending between the protrusions 210, and the extension arm 310 is also provided with through holes through which the rotating shaft 112 passes. In this way, the stirring paddle 300 and the scraper 200 can be fixed.

[0028] Please refer to in combination Figures 1 to 3 , the pin head 111 is provided with a positioning hole D11, and the lower end of the rotating shaft 112 is provided with a first fixing hole D12 and a second fixing hole D13 at intervals. The retaining pin 120 is formed by bending an elastic plastic fixing strip, and specifically, spring stainless steel can be used. The elastic plastic fixing strip passes through the positioning hole D11, and a positioning portion 121 is formed by bending at the positioning hole D11. The retaining pin 120 can be prevented from falling off during disassembly and assembly through the positioning portion 121. Preferably, the width of the positioning portion 121 is 1.1 to 1.3 times the diameter of the pin head 111, which can make the torque uniform while maintaining the installation convenience.

[0029] Please refer to Figure 1 , Figure 2 , Figure 4, after bending to form the positioning portion 121, its two ends extend and then fold back respectively through the first fixing hole D12 and the second fixing hole D13, and at the same time, positioning grooves 122 are provided at the embedded sections of the elastic and plastic fixing strip and the first fixing hole D12 and the second fixing hole D13. By utilizing the elastic and plastic characteristics of the elastic and plastic fixing strip, it bends and folds back through the fixing holes, and positioning grooves 122 are provided at the embedded sections with the fixing holes, so that the bolt 100 can firmly fix the emulsifier stirring paddle 300. Here, the fixing holes refer to the first fixing hole D12 and the second fixing hole D13. Preferably, the width of the positioning groove 122 is 1.2 to 1.5 times the diameter of the rotating shaft 112, which can meet the force requirements and is also convenient for shuttling and fixing. Further, considering the convenience of shuttling and fixing, the positioning hole D11, the first fixing hole D12, and the second fixing hole D13 are axially parallel in the same plane.

[0030] Please refer to Figure 2 and Figure 5 , in some preferred embodiments, in order to make the elastic and plastic fixing strip more stable during installation and at the same time give full play to its elastic characteristics, after the elastic and plastic fixing strip forms the positioning portion 121 by bending at the positioning hole D11, its two ends extend outward in the opposite direction and then fold back to form elastic portions 123. Specifically, the elastic portion 123 can form a U-shaped deflection ring 124 at the reverse bending position.

[0031] Please refer to Figure 1 and Figure 5 , as described above, the elastic portion 123 forms a U-shaped deflection ring 124 at the reverse bending position. At this time, the elastic portions 123 at both ends will show a staggered shape. In the preferred solution, the positioning hole D11, the first fixing hole D12, and the second fixing hole D13 are in an axially parallel state in the same plane. Therefore, in order to make the end portion thereof align with the first fixing hole D12 or the second fixing hole D13, an alignment bending section 125 is provided on the elastic portion 123. When the elastic portion is on the inner side, its alignment bending section 125 bends outward, and vice versa. The inner and outer bending directions thereof and the corresponding relationship between the end portion of the expected anti-withdrawal pin 120 and the first fixing hole D12 or the second fixing hole D13 are not limited herein.

[0032] As described above, the present case protects a bolt assembly and the emulsifier rotating mechanism to which it is applied. All technical solutions that are the same as or similar to the present case should be regarded as falling within the protection scope of the present case.
