Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a multifunctional experimental table with an adjustable tilt angle. Background Technology

[0002] In scientific research, teaching experiments, and industrial testing, the experimental platform serves as the basic platform for supporting experimental devices or samples. Its functionality and adaptability directly affect the accuracy and efficiency of the experiment. With the diversification of experimental needs, many experiments need to be conducted at different tilt angles, such as fluid flow characteristics research, material slip performance testing, optical component angle calibration, and solar panel efficiency testing. Therefore, experimental platforms with tilt angle adjustment functions have gradually become important equipment in laboratories.

[0003] Currently, common adjustable tilt test benches use linkage mechanisms, hinged arms, or rotating supports to rotate the table surface around a fixed axis to achieve angle adjustment. However, this method lacks a reliable locking mechanism after angle adjustment, and the angle is prone to shift due to external forces or vibrations during long-term use, which seriously affects the stability and safety of experimental data.

[0004] Therefore, there is a need for a multifunctional experimental platform with an adjustable tilt angle and a locking mechanism. Utility Model Content

[0005] In order to overcome the shortcomings of existing adjustable tilt experimental tables that use linkage mechanisms, hinged arms or rotating supports to drive the table surface to rotate around a fixed axis for angle adjustment, which lack a reliable locking mechanism and are prone to angle deviation due to external forces or vibrations, this utility model provides a multifunctional experimental table surface with adjustable tilt angle and a locking mechanism.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a multifunctional experimental tabletop with adjustable tilt angle, comprising a chassis, a mounting frame on the top of the chassis, a servo motor mounted on the right side of the mounting frame, and a rotating frame rotatably connected to the left side of the mounting frame. The rotating frame is connected to the output shaft of the servo motor, and the experimental tabletop is fixedly mounted on the rotating frame. Symmetrically distributed arc-shaped guide discs are provided on both sides of the chassis, each with multiple positioning holes. Long locking rods are slidably threaded through both sides of the experimental tabletop, with one end extending horizontally to the right and the other end connected to a locking frame. The locking frame is located on the left side of the experimental tabletop and can slide along the contour of the arc-shaped guide discs. Symmetrically arranged short locking rods are provided on the locking frame. A push cylinder is mounted on the left side of the mounting frame, and the movable rod of the push cylinder is rotatably connected to the locking frame.

[0007] In a preferred embodiment of this utility model, the rotating frame is connected to the output shaft of the servo motor by a key.

[0008] In a preferred embodiment of this utility model, the top of the experimental platform is provided with several anti-slip grooves.

[0009] In a preferred embodiment of the present invention, the plurality of positioning holes are evenly distributed along the arc of the arc-shaped guide plate, and each positioning hole corresponds to a different tilt angle position.

[0010] In a preferred embodiment of this utility model, a honeycomb core stainless steel base is provided at the bottom of the chassis, and a guide cylinder is provided at the corner of the honeycomb core stainless steel base. A shock-absorbing rod is slidably provided on each guide cylinder. The upper end of the shock-absorbing rod is fixedly connected to the bottom of the chassis, and a shock-absorbing spring is connected between its lower end and the guide cylinder, thereby forming a damping shock absorption structure.

[0011] In a preferred embodiment of this utility model, a support frame is provided in the middle of the mounting frame, and the support frame is provided with a through hole, through which the rotating frame rotates to form a central support.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a locking mechanism driven by a push cylinder, and cooperating with multiple positioning holes on the arc-shaped guide plate, after the angle is adjusted to the position, the long locking rod and the short locking rod are simultaneously inserted into the positioning holes to achieve multi-point rigid locking of the table. This locking method has strong anti-disturbance ability and effectively prevents the table angle from shifting due to external vibration, collision or load shift, significantly improving the stability and safety of the experimental process.

[0013] 2. By setting a damping and vibration reduction structure consisting of guide cylinders, shock absorbers and shock absorbers between the chassis and the honeycomb core stainless steel base, the transmission of ground vibration to the experimental platform can be effectively isolated, further improving the overall vibration resistance performance of the machine.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Example 1: Please refer to Figure 1 and Figure 2 A multi-functional experimental workbench with adjustable tilt angle includes a base 1. A mounting bracket 2 is mounted on the top of the base 1. A servo motor 3 is mounted on the right side of the mounting bracket 2, and a rotating frame 4 is rotatably connected to the left side of the mounting bracket 2. The rotating frame 4 is connected to the output shaft of the servo motor 3 via a key to achieve synchronous rotation. Furthermore, the key connection facilitates assembly and disassembly while ensuring reliable torque transmission. An experimental workbench 5 is fixedly mounted on the rotating frame 4. The top of the experimental workbench 5 has several anti-slip grooves to enhance the stability of placed items. The base 1 has symmetrically distributed arc-shaped guide plates 6 on both sides, each with nine positioning holes. These nine positioning holes are evenly distributed along the arc of the arc-shaped guide plates 6, and each positioning hole corresponds to a different... The tilt angle position facilitates quick identification and setting of the required angle by the operator. Long locking rods 7 are slidably installed on both the front and rear sides of the experimental table 5. One end of the long locking rod 7 extends horizontally to the right, and the other end is connected to a locking frame 8. The locking frame 8 is located on the left side of the experimental table 5 and can slide along the contour of the arc-shaped guide plate 6. Short locking rods 9 are provided on the locking frame 8 symmetrically. A push cylinder 10 is installed on the left side of the mounting frame 2. The movable rod of the push cylinder 10 is rotatably connected to the locking frame 8 and is used to drive the locking frame 8 to move along the arc-shaped path. A support frame 14 is provided in the middle of the mounting frame 2. The support frame 14 has a through hole, through which the rotating frame 4 rotates to form a central support, which significantly enhances its structural stability during rotation.

[0020] When it is necessary to adjust the tilt angle of the experimental platform 5, the servo motor 3 is started, and its output shaft drives the rotating frame 4 to rotate, thereby driving the experimental platform 5 to tilt. During the rotation, the long locking rod 7 fixed to the experimental platform 5 moves in an arc, and its left end drives the locking frame 8 to slide synchronously along the contour of the arc-shaped guide discs 6 on the left and right sides. When the experimental platform 5 is rotated to the target tilt angle, and the positions of the long locking rod 7 and the short locking rod 9 are aligned with the corresponding positioning holes on the arc-shaped guide discs 6, the push cylinder 10 is started, the movable rod extends to the right, and pushes the locking frame 8 to move to the right, so that the long locking rod 7 and the short locking rod 9 are inserted into the corresponding positioning holes at the same time, thereby achieving rigid locking of the experimental platform 5 and preventing it from shifting in angle due to external vibration, collision or load eccentricity. After locking, the experimental platform 5 is stably maintained at the set angle, and related experimental operations can be performed.

[0021] Example 2: Based on Example 1, please refer to... Figure 3 The bottom of the chassis 1 is provided with a honeycomb core stainless steel base 11, and guide cylinders 12 are provided at the four corners of the honeycomb core stainless steel base 11. Each guide cylinder 12 is slidably provided with a shock-absorbing rod 13. The upper end of the shock-absorbing rod 13 is fixedly connected to the bottom of the chassis 1, and the lower end is connected to the guide cylinder 12 with a shock-absorbing spring 1301, thereby forming a damping shock absorption structure.

[0022] When external vibrations or impacts are transmitted to the ground, the honeycomb core stainless steel base 11 provides initial vibration isolation. If the experimental platform 5 or the chassis 1 is subjected to vertical vibration or impact loads, the chassis 1 will tend to move up and down. At this time, the damping rod 13 slides in the guide cylinder 12, which drives the damping spring 1301 to compress. The spring absorbs and dissipates the vibration energy and provides a restoring force, so that the chassis 1 returns to its position quickly. The guide cylinder 12 and the damping rod 13 work together to achieve precise guidance, prevent lateral swaying, and ensure smooth movement.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
