Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a structure for preventing the lifting rod of a small mixer from rotating. Background Technique

[0002] A mixer is a fluid mixing device, mainly used in industries such as chemical industry, medicine, food, mining, papermaking, and wastewater treatment. It is a machine in which a shaft with a mixing head rotates in a container to mix multiple raw materials into a mixture or a mixture with a suitable consistency. Generally, the mixer will contain a mixing head inside. When the mixing head is mixing, it will shake and turn, so it is necessary to limit its rotation to prevent it from turning. For the head support frame of existing domestic small mixers, in order to make the lifting stable and the mixing head not rotate and turn, square tubes or round tubes are mostly used in combination with guide rails for support. The above two methods have a large number of parts, occupy a large overall space, and are relatively heavy. Content of the Utility Model

The above two methods have a large number of parts, occupy a large overall space, and are relatively heavy.

[0004] To achieve the above object, the utility model provides the following technical solution: A structure for preventing the lifting rod of a small mixer from rotating, including a lifting rod, a guide seat is sleeved on the outer surface of the lifting rod, a fixed rod is fixedly connected to the lower end of the guide seat, a guide copper rod is arranged inside the right side of the guide seat, and a tightening screw is arranged on the right side of the guide copper rod.

[0005] By adopting the above technical solution, through setting

[0006] Preferably, a flat surface is machined on the outer circular surface of the lifting rod.

[0007] By adopting the above technical solution, by machining a flat surface on the outer circular surface of the lifting rod, it can facilitate the left end surface of the copper rod on the right side to fit more closely with its flat surface.

[0008] Preferably, the left outer end surface of the guide copper rod is in movable contact with the flat surface machined on the outer circular surface of the lifting rod, and the right outer end surface of the guide copper rod is in movable contact with the left outer end surface of the tightening screw.

[0009] Preferably, the outer surface of the fixed rod is fixedly connected to the inner surface of the guide seat, and the outer surface of the lifting rod can slide up and down with the inner surface of the guide seat.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The structure for preventing the lifting rod of a small mixer from rotating is such that a guide seat is sleeved on the outer surface of the lifting rod. A fixed rod is fixedly connected to the lower end of the guide seat. A guide copper rod is arranged inside the right side of the guide seat, and a tightening screw is arranged on the right side of the guide copper rod. The mixer head is connected to the upper end of the lifting rod. The lifting and lowering of the mixer head are realized by the up-and-down sliding of the lifting rod. A flat surface is machined on the outer circular surface of the lifting rod. The guide copper rod is close to the flat surface, and the movement of the guide copper rod is prevented by using the tightening screw, so that the lifting rod will not rotate when lifting and lowering, thereby achieving the purpose of limiting the mixer head to prevent shaking and turning in a more compact and simple manner.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1 , when using the present utility model, in order to solve the problem that the support frame of the mixer head of existing domestic small mixers uses square tubes or round tubes with guide rails to support in order to make the lifting stable and the mixing head does not rotate or turn. The above two methods have a large number of parts, a large overall occupied space, and a relatively large weight. A guide seat 2 is sleeved on the outer surface of the lifting rod 1, a fixed rod 3 is fixedly connected to the lower end of the guide seat 2, a guide copper rod 4 is arranged inside the right side of the guide seat 2, and a tightening screw 5 is arranged on the right side of the guide copper rod 4.

[0017] Working principle: When using the structure for preventing the lifting rod of a small mixer from rotating, the mixer head is connected to the upper end of the lifting rod 1. The up-and-down sliding of the lifting rod 1 realizes the up-and-down movement of the mixer head. A flat surface is machined on the outer circular surface of the lifting rod 1. The guide copper rod 4 is close to the flat surface, and the movement of the guide copper rod 4 is prevented by using the tightening screw 5, so that the lifting rod 1 will not rotate when lifting and lowering.
