Description

Technical Field

[0001] This utility model relates to the technical field of training devices, and in particular to a rotatable threaded connection training device. Background Technology

[0002] In the maintenance of subway vehicles and other large equipment, the assembly and disassembly of components largely rely on threaded connections. As one of the most common mechanical connection methods, threaded connections are widely used in various mechanical structures due to their high reliability, repeatable assembly and disassembly, and strong load-bearing capacity. For students and maintenance personnel in related fields, mastering the operation skills of threaded connections is an important foundation for improving assembly quality and maintenance efficiency.

[0003] Currently, universities and training institutions typically use specialized training equipment to conduct threaded connection skills training. However, existing training equipment generally suffers from drawbacks such as high cost, large size, and complex layout, resulting in most institutions being unable to equip themselves with a sufficient number of devices. They are forced to teach using a limited number of training stations, severely restricting students' practical opportunities and training effectiveness. Furthermore, some existing devices have relatively fixed structural designs, making it difficult to simulate real connection scenarios from multiple angles and directions. The training content is also limited and cannot fully cover the diverse working conditions that may be encountered in actual maintenance processes.

[0004] With the increasing maintenance needs of subway vehicles and large equipment, practical training demands greater diversity and flexibility in equipment. Existing equipment has significant shortcomings in simulating real working conditions, making it difficult to effectively train trainees' ability to perform threaded connections at different angles. Furthermore, the large footprint and inconvenient transportation and installation of traditional training equipment also limit its promotion and widespread adoption.

[0005] In view of this, the inventors specifically designed a rotatable threaded connection training device, which led to this invention. Utility Model Content

[0006] The purpose of this application is to provide a rotatable threaded connection training device, which at least solves the problems of existing threaded connection training equipment being costly, occupying a large area, and unable to flexibly adapt to multi-angle and multi-directional threaded connection working conditions.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a rotatable threaded connection training device, characterized in that it includes: a base frame for supporting the overall structure of the device; a rotating shaft rotatably mounted on the base frame; a rotating handle fixedly connected to the rotating shaft for driving the rotating shaft to rotate; a mounting plate fixedly connected to the output end of the rotating shaft; and a connecting plate disposed on the mounting plate, the connecting plate having multiple connecting holes for connecting to external plates via bolts; wherein, when the rotating handle drives the rotating shaft to rotate, it causes the connecting plate to rotate at an angle.

[0008] In a further embodiment, the rotary handle is fixed to the rotary shaft via a key connection.

[0009] In a further embodiment, the rotating shaft and the base frame are rotatably connected via a bearing seat.

[0010] In a further embodiment: the bearing seat includes an upper cover plate and a lower cover plate, the lower cover plate being fixed to the base frame by bolt one; the upper cover plate and the lower cover plate being fixed by bolt two.

[0011] In a further embodiment: the rotating shaft is connected to the upper cover plate and the lower cover plate by an interference fit.

[0012] In a further embodiment, the mounting plate and the rotating shaft are connected by an interference fit.

[0013] In a further embodiment, the mounting plate is provided with multiple connecting plates around its perimeter. These connecting plates are formed by bending and are fixedly connected to the mounting plate by bolts.

[0014] In a further embodiment, the connecting holes are distributed in an equidistant array.

[0015] In a further embodiment, the base frame is a metal frame.

[0016] Compared with the prior art, the present invention has the following advantages: By setting a rotatable rotating shaft on the base frame and driving the mounting plate and its surrounding connecting plates to rotate via a rotating handle, the angle of the connecting plates can be adjusted, simulating threaded connection conditions in different orientations. Compared with existing training equipment that is bulky, costly, and has a fixed training angle, this utility model has a compact structure, occupies a small area, and the evenly distributed connecting holes on the connecting plates can be flexibly combined with external plates, which reduces equipment investment costs and improves the diversity and practicality of threaded connection skill training.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1 and Figure 2 As shown, the rotatable threaded connection training device provided by this utility model includes a base frame 1, a rotating shaft 2, a rotating handle 3, a mounting plate 4, and multiple connecting plates 5. The base frame 1 serves as the load-bearing foundation and adopts a metal frame structure, possessing high stability and load-bearing capacity. Mounting holes are provided on the frame for easy fixed connection with the training workbench, ensuring that the device will not shift during training. The rotating shaft 2 is rotatably mounted on the base frame 1 via a shaft seat 7, which consists of an upper cover plate 71 and a lower cover plate 72. The lower cover plate 72 is fixed to the base frame 1 by bolt 81, and the upper cover plate 71 and the lower cover plate 72 are locked together by bolt 82 to form an integral clamping structure. An interference fit is used between the rotating shaft 2 and the upper and lower cover plates 72 to ensure rotational stability and positioning accuracy.

[0022] like Figure 3 and Figure 5As shown, the rotating handle 3 is fixedly installed at one end of the rotating shaft 2, preferably by a key 6, to achieve a reliable transmission relationship. The rotating handle 3 can be designed as an L-shaped or T-shaped structure so that the operator can apply torque during training to easily drive the rotating shaft 2 to rotate. The other end of the rotating shaft 2 is fixedly connected to the mounting plate 4, preferably by an interference fit, so that the mounting plate 4 can rotate synchronously with the rotating shaft 2. The mounting plate 4 is located at the core of the device, and multiple bending connecting plates 5 are evenly distributed around it. Each connecting plate 5 is fixed to the mounting plate 4 by bolts 83, forming a stable overall structure.

[0023] like Figure 4 As shown, each connecting plate 5 has multiple connecting holes 51 arranged in an equidistant array, ensuring both balanced mechanical properties and convenient flexible installation of external plates. The external plates are metal plates with through holes corresponding to the connecting holes 51, allowing for assembly and disassembly operations required for training via bolt connections. During training, operators can rotate the connecting plate 5 by rotating the handle 3, allowing the connecting holes 51 to be positioned at different angles, thus simulating multi-directional and multi-position threaded connections in actual maintenance.

[0024] In further optimized designs, spring washers can be used with bolted connections to enhance connection reliability and prevent loosening caused by frequent training operations. Simultaneously, the surface of the connecting plate 5 can be machined with an anti-slip texture, allowing operators to perform assembly operations more securely during training. To improve service life, a bushing can be fitted onto the rotating shaft 2, creating a low-friction fit between the bushing and the base frame 1 to reduce wear.

[0025] Through the above structural design, this utility model device not only provides a stable training environment for threaded connections within a limited space, but also enables multi-angle adjustment by rotating the handle 3 to drive the mounting plate 4 and connecting plate 5, fully simulating the diverse requirements of actual maintenance scenarios. Compared with traditional large-scale training equipment, this device has the advantages of compact structure, small footprint, and low manufacturing cost, and the training method is more flexible, which can significantly improve students' or trainees' mastery of threaded connection skills.

[0026] In summary, this utility model, through a reasonable structural layout, organically combines the functions of base frame 1 support, rotational transmission, installation and fixing, and multi-directional connection, thus realizing a low-cost and highly practical threaded connection training device.

[0027] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
