Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a vibratory rod based on a flexible shaft that can be bent arbitrarily. Background Technology

[0002] Concrete is a widely used building material in the construction industry. Because concrete contains a large amount of gas and moisture after mixing, its density must be maintained to ensure it reaches its design strength. Concrete vibration equipment is used in concrete construction to improve this density. Currently, the vibration equipment commonly used in the construction industry can only vibrate vertically downwards. It cannot turn around at angled locations on certain structures, making it unable to reach the areas requiring vibration, resulting in substandard project quality. Utility Model Content

[0003] The purpose of this invention is to provide a vibrating rod based on a flexible shaft that can be bent arbitrarily, thereby solving the problem that the existing vibrating equipment can only vibrate vertically downwards, and cannot turn around when encountering some special structural parts, thus failing to reach the parts that need to be vibrated, resulting in the project quality not meeting the construction requirements.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a vibrating rod based on a flexible shaft that can be bent arbitrarily, comprising a rod head body, a flexible rod shell connected to the rod head body, a connector connected to the flexible rod shell and located away from the rod head body, and a transmission rib passing through the connector and the interior of the flexible rod shell and connected to the rod head body. The flexible rod shell contains multiple steering bodies; each steering body includes a rotating head, a connecting body, and a support shaft; the support shaft is located between the connecting body and the rotating head; the rotating head, connecting body, and support shaft are all provided with communicating through holes; the connecting body has a cavity inside that matches the shape of the rotating head; multiple steering bodies are sequentially connected by inserting the rotating head of one steering body into the cavity of an adjacent connecting body, thereby forming a flexible shaft; the support shaft contains a first positioning bearing that cooperates with the transmission rib; and the outer side of the rotating head is fitted with a damping ring that fits against the inner wall of the cavity.

[0005] Furthermore, the rotating head has a cavity for receiving transmission ribs.

[0006] Furthermore, the flexible rod shell is made of flexible plastic.

[0007] Furthermore, the rod head body is provided with a bearing receiving cavity, the top of the bearing receiving cavity is provided with a second positioning bearing, the bottom of the bearing receiving cavity is provided with a third positioning bearing, an eccentric swing rod is provided between the second positioning bearing and the third positioning bearing, and the transmission rib is connected to the eccentric swing rod.

[0008] Furthermore, the connector is threadedly connected to the flexible rod housing, and a fourth positioning bearing is provided inside the connector. The transmission rib passes through the fourth positioning bearing and connects to the interior of the flexible rod housing.

[0009] Furthermore, the connector is also equipped with an oil seal gasket.

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

[0011] 1. Multiple steering bodies are sequentially connected by inserting the rotating head of one steering body into the cavity of the adjacent connecting body, thereby forming a flexible shaft. This enables the flexible rod shell to rotate, and the rotation angle can be maintained by the damping ring. The flexible rod shell can be bent to any angle. This can solve the problem that some vibratory rods with special angles cannot be bent during construction and cannot be inserted into the angle for vibration, resulting in the project quality not meeting the construction requirements.

[0012] 2. By providing a support shaft between the rotating head and the connecting body, and installing a first positioning bearing inside the support shaft, and using a flexible transmission rib as the power transmission component for the vibration of the rod head, the transmission rib is supported between the rotating head and the connecting body by the first positioning bearing. This ensures that when the flexible rod shell is bent, the transmission rib is supported by the support shaft and the first positioning bearing at the center position of the rotating head and the connecting body. Furthermore, the connecting body has a cavity that matches the shape of the rotating head, and the rotating head has a cavity for receiving the transmission rib. This ensures that the transmission rib will not touch the inside of the rotating head and the connecting body when bending, thus ensuring the normal rotation of the transmission component.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0022] like Figures 1 to 5 As shown, this utility model provides a vibratory rod based on a flexible shaft that can be bent arbitrarily, including a rod head body 1, a flexible rod shell 2 connected to the rod head body 1, a connector 3 connected to the flexible rod shell 2 and located away from the rod head body 1, and a transmission rib 4 passing through the connector 3 and the interior of the flexible rod shell 2 and connected to the interior of the rod head body 1. The flexible rod shell 2 is provided with multiple steering bodies 21, each steering body 21 including a rotating head 211, a connecting body 212, and a support shaft 213. The support shaft 213 is located between the connecting body 212 and the rotating head 211. The rotating head 211, the connecting body 212, and the support shaft 213 are all provided with communicating through holes 214. The connecting body 212 has a cavity 215 formed inside that matches the shape of the rotating head 211, and the cavity 215 has dimensional tolerances. Within a predetermined range, the rotating head 211 can be tightly and smoothly connected to the connecting body 212. The rotating head 211 is a sphere and has the transmission rib receiving cavity 216 inside. Multiple steering bodies 21 are connected sequentially by inserting the rotating head 211 of one steering body 21 into the cavity 215 of the connecting body 212 of the adjacent steering body 21, forming a connection relationship that is both tightly fitted and can rotate relative to each other. The rotating head 211 and the connecting body 212 cooperate with each other to ensure that the flexible shaft will not loosen or disengage when bending, and to allow the rotating head 211 to rotate flexibly within the connecting body 212. The support shaft 213 is provided with a first positioning bearing 217 that cooperates with the transmission rib 4. The outer side of the rotating head 211 is fitted with a damping ring 218 that fits against the inner wall of the cavity 215.

[0023] The flexible rod shell 2 is made of flexible plastic; the flexible rod shell 2 is made of flexible ABS plastic with a hollow structure and a smooth surface. When the flexible rod shell 2 is sleeved on the outside of the flexible shaft, it can bend with the bending of the flexible shaft and has wear-resistant properties, which makes it have a long service life when vibrating cement.

[0024] The rod head body 1 is provided with a bearing receiving cavity 11. A second positioning bearing 12 is provided at the top of the bearing receiving cavity 11, and a third positioning bearing 13 is provided at the bottom. An eccentric swing rod 14 is provided between the second positioning bearing 12 and the third positioning bearing 13. The transmission rib 4 is connected to the eccentric swing rod 14. The second positioning bearing 12 positions and supports one end of the eccentric swing rod 14 from above, restricting its displacement in the vertical direction and ensuring that it can rotate stably around its own axis. The third positioning bearing 13 plays a similar role from below. The two positioning bearings work together to ensure that the eccentric swing rod 14 is stably installed in the bearing receiving cavity 11. The eccentric swing rod 14 is one of the core components for realizing the vibration function of the rod head body 1. It has an eccentric structure, that is, its mass distribution is uneven and its rotation center does not coincide with its geometric center. The transmission rib 4 is connected to the eccentric pendulum 14. When the transmission rib 4 receives the rotational power from an external power source (such as a motor or other driving device), the transmission rib 4 starts to rotate. Due to its connection with the eccentric pendulum 14, it will drive the eccentric pendulum 14 to rotate around its axis.

[0025] The connector 3 is threadedly connected to the flexible rod housing 2. The connector 3 is provided with a fourth positioning bearing 31. The transmission rib 4 passes through the fourth positioning bearing 31 and is connected to the interior of the flexible rod housing 2, so that the rotation of the transmission rib 4 is smoother.

[0026] The connector 3 is also equipped with an oil seal gasket 5. The oil seal gasket 5 is usually made of rubber or other elastic materials with good sealing performance. Its shape and size are adapted to the sealing area inside the connector 3. The oil seal gasket 5 is installed in the gap between the connector 3 and the flexible rod housing 2. It fills the possible tiny gaps through its own elastic deformation, thereby forming a sealing barrier. The oil seal gasket 5 can effectively prevent mud from entering the flexible rod housing 2 and prevent the oil inside the flexible rod housing 2 from leaking to the external environment.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
