Description

Technical Field

[0001] The present application belongs to the field of lithium battery mixer structure, and specifically relates to a lightweight mixer. Background Art

[0002] Lithium-ion mixers are common mixing equipment. Due to their portability, their use scenarios are becoming more and more diverse. During operation, operators hold the mixer handle to mix the materials. Current mixers are heavy and have high transportation costs. At the same time, the heavy weight, especially the heavy weight of the mixing rod head, can cause arm fatigue after using the mixer for a period of time. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a light-weight mixer that can solve the problem of heavy weight of existing mixers in the related art.

[0004] The embodiment of the present application provides a lightweight structure mixer, comprising:

[0005] A connecting rod, wherein the connecting rod is a hollow structure;

[0006] A stirring device, the stirring device is connected to the connecting rod;

[0007] The stirring device comprises: a support shaft, a support ring and a plurality of stirring rods distributed around the axis of the support shaft, wherein the support ring is connected to the support shaft or the stirring rod. By setting the connecting rod as a hollow structure, the weight of the stirring device can be effectively reduced.

[0008] Furthermore, the stirring device is threadedly connected to the connecting rod, the supporting rod on the stirring device is provided with an internal thread, and the connecting rod is provided with an external thread matching the internal thread on the supporting rod. The two are directly threadedly connected, which is convenient for disassembly, and at the same time, the transition piece between the two can be omitted to reduce weight.

[0009] Furthermore, the stirring device is threadedly connected to the connecting rod, the support member on the stirring device is provided with an external thread, and the connecting rod is provided with an internal thread matching the external thread on the supporting rod. The two are directly threadedly connected, which is convenient for disassembly, and at the same time, the transition piece between the two can be omitted to reduce weight.

[0010] Furthermore, the stirring device is connected to the connecting rod via a transition piece, and the transition piece is provided with a cut surface for convenient engagement on the outside. The cut surface is convenient for engagement, rotation and disassembly by a wrench.

[0011] Furthermore, the thickness D of the connecting rod is 0.2 to 0.8 times the outer diameter of the connecting rod. The thickness D of the connecting rod should be appropriately selected according to the outer diameter of the connecting rod. The thickness D is selected as small as possible based on the strength requirement. This can reduce the weight of the connecting rod to the greatest extent.

[0012] Furthermore, the outer diameter of the connecting rod is equal to that of the supporting shaft. Both the connecting rod and the supporting shaft are hollow structures, and the thickness D on the connecting rod should be equal to or similar to that on the supporting shaft. This makes the dimensions uniform and beautiful, and can reduce the weight of the stirring device to the greatest extent.

[0013] The technical solution is mainly to set the connecting rod, the support shaft and the support ring as hollow structures, so as to effectively reduce the weight of the stirring device and reduce the transportation cost, and at the same time, reduce the fatigue of long-term use of the lithium battery mixer.

[0019] Example 1

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] In the following, in combination with the accompanying drawings, a lightweight structure mixer provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0022] refer to Figure 1-3 , a lightweight structure mixer provided in an embodiment of the present application may include:

[0023] A connecting rod 1, wherein the connecting rod 1 is a hollow structure;

[0024] A stirring device 6, wherein the stirring device 6 is detachably connected to the connecting rod 1;

[0025] The stirring device 6 includes: a support shaft 5, a support ring 4 and a plurality of stirring rods 3 distributed around the axis of the support shaft 5. The stirring rods 3 are evenly distributed around the axis of the support shaft 5, so that the center of gravity of the stirring device 6 can be kept stable. The support ring 4 is fixedly connected to the support shaft 5 and / or the stirring rods 3.

[0026] Further, the stirring device 6 is threadedly connected to the connecting rod 1, the supporting shaft 5 on the stirring device 6 is provided with an internal thread, and the connecting rod 1 is provided with an external thread matching the internal thread provided on the supporting shaft 5. Or the stirring device 6 is threadedly connected to the connecting rod 1, the supporting shaft 5 on the stirring device 6 is provided with an external thread, and the connecting rod 1 is provided with an internal thread matching the external thread provided on the stirring device 6. The purpose is to allow the two to be directly connected, which can save transitional connecting parts and then save weight.

[0027] The stirring device 6 is connected to the connecting rod 1 through a transition piece 2, and the transition piece 2 is provided with an internal thread structure. At this time, the connection between the support shaft 5 and the transition piece 2 has an external thread structure that matches the internal thread on the transition piece 2. The connecting rod 1 is provided with a cut surface for convenient engagement with the outside of the transition piece 2. The engaging cut surface is convenient for engagement and rotation of a wrench for disassembly. The transition piece 2 is used for easy disassembly.

[0028] Furthermore, the outer diameters of the connecting rod 1 and the supporting shaft 5 are equal, and both the connecting rod 1 and the supporting shaft 5 are hollow structures. The hollow structure of the supporting shaft 5 can further reduce the weight of the stirring device 6 .

[0029] Furthermore, the support ring 4 is also a hollow structure. The support ring 4 is preferably an annular hollow tube structure, but it can also be an open structure with a certain thickness, such as a U-shaped structure or a V-shaped structure. The purpose is to reduce its own weight on the basis of meeting the requirements of strength and rigidity. On the entire stirring device 6, the hollow structure of the support ring 4 and the support shaft 5 can reduce the weight to the maximum extent. The wall thickness of the support ring 4 can be calculated with reference to the thickness D of the connecting rod 1.

[0030] like Figure 2 As shown, the thickness D of the connecting rod 1 is the wall thickness of the connecting rod 1, and the thickness D is 0.2 to 0.8 times the outer diameter of the connecting rod 1. Preferably, the thickness D is 0.4 times the outer diameter of the connecting rod 1, so that the weight of the connecting rod 1 can be reduced to the maximum extent on the basis of meeting the strength of the stirring condition. This can reduce transportation costs and reduce fatigue caused by long-term use of the lithium-ion mixer.

[0031] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
