[0002] Currently, after relays are manufactured, their vibration frequency needs to be tested after being powered on to ensure the stability of the products leaving the factory. During vibration testing, it's necessary to simulate the relay's installation angle under different scenarios. The current simulation method typically involves manually rotating the relay to a preset angle and then mounting it on a fixed bracket before conducting the vibration test. However, this method is time-consuming and labor-intensive, with high labor and time costs, low rotation efficiency, and low rotation accuracy.

[0003] Therefore, there is an urgent need for a vibration testing equipment product that is time-saving, labor-saving, highly efficient, and highly accurate. Utility Model Content

[0010] As one possible implementation, the rotating mechanism also includes a limiting block, a mounting bracket is provided with limiting screws, the limiting block is connected to the rotating shaft, and the limiting screws are used to abut against the limiting block to limit the extreme position of the rotating shaft.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0026] Please refer to the reference. Figures 1 to 4 This utility model provides a rotating mechanism 100 for driving an object to rotate. It can realize the automated rotation of the object to be rotated 200, saving time and effort, reducing labor and time costs, improving rotation efficiency, and improving rotation accuracy.

[0027] The rotating mechanism 100 includes a mounting frame 110, a telescopic drive member 120, a connecting rod 130, and a rotating shaft 140. The telescopic drive member 120 is rotatably mounted on the mounting frame 110 and rotatably connected to the connecting rod 130. The telescopic drive member 120 can extend or retract to drive the connecting rod 130 to rotate. During this process, the telescopic drive member 120 itself also rotates relative to the mounting frame 110 to ensure transmission stability. The rotating shaft 140 is rotatably engaged with the mounting frame 110 and can rotate relative to the mounting frame 110. The mounting frame 110 can limit the rotation of the rotating shaft 140. One end of the rotating shaft 140 is connected to the connecting rod 130, and the other end is used to connect to the object to be rotated 200. Under the action of the telescopic drive member 120, the connecting rod 130 can rotate relative to the mounting frame 110, thereby driving the object to be rotated 200 to rotate.

[0028] The rotating mechanism 100 provided in this application enables the automated rotation of the object 200 to be rotated by rotating the telescopic drive member 120 mounted on the mounting frame 110 and the rotating shaft 140 connected to the connecting rod 130. This saves time and effort, reduces labor and time costs, and improves rotation efficiency and accuracy. Furthermore, in the application of the rotating mechanism 100, the linear thrust of the telescopic drive member 120 is converted into the torque of the connecting rod 130, thereby driving the rotating shaft 140 to rotate. This effectively reduces the size and weight of the rotating mechanism 100, improves structural compactness, facilitates installation and use, has strong versatility, and reduces production costs, thus improving economic efficiency.

[0029] The telescopic drive component 120 includes a rotating block 121, a cylinder 122, and an extension rod 123. The mounting bracket 110 is equipped with a positioning pin 111. One end of the cylinder 122 is connected to the rotating block 121, and the rotating block 121 rotatably engages with the positioning pin 111, allowing the rotating block 121 to rotate relative to the positioning pin 111. The positioning pin 111 limits the movement of the rotating block 121. The other end of the cylinder 122 is equipped with a telescopic rod 124, which is rotatably connected to the connecting rod 130 via the extension rod 123. The telescopic rod 124 can extend or retract from the cylinder 122 to drive the connecting rod 130.

[0030] The connecting rod 130 includes a connecting seat 131, a first side plate 132, and a second side plate 133. The first side plate 132 and the second side plate 133 are arranged opposite to each other and are both connected to the connecting seat 131. The connecting seat 131 is connected to the rotating shaft 140. The extension rod 123 is partially disposed between the first side plate 132 and the second side plate 133 and is hinged to the first side plate 132 and the second side plate 133 through a hinge shaft 134 to realize the rotational connection between the connecting rod 130 and the extension rod 123. This allows the extension rod 123 to rotate relative to the first side plate 132 and the second side plate 133 under the drive of the telescopic rod 124. The first side plate 132 and the second side plate 133 work together to limit the extension rod 123 and prevent the extension rod 123 from detaching from the connecting rod 130.

[0031] Furthermore, a connecting ring 125 is provided at the end of the extension rod 123 away from the telescopic rod 124. The connecting ring 125 is located between the first side plate 132 and the second side plate 133 and is sleeved on the hinge shaft 134. A bearing (not shown) is provided between the connecting ring 125 and the hinge shaft 134. The bearing is used to reduce the frictional force of the connecting ring 125 rotating relative to the hinge shaft 134, so as to improve the stability of the transmission of the rotating mechanism 100.

[0032] In this embodiment, the connecting seat 131 includes a first clamping block 135 and a second clamping block 136 spaced apart. The rotating shaft 140 is clamped between the first clamping block 135 and the second clamping block 136. The first clamping block 135 and the second clamping block 136 work together to clamp and fix the rotating shaft 140. Specifically, one end of each of the first clamping block 135 and the second clamping block 136 is connected to the first side plate 132 and the second side plate 133, and the other end is connected by bolts (not shown). The bolts are used to limit the relative position of the first clamping block 135 and the second clamping block 136, thereby ensuring the stability of the first clamping block 135 and the second clamping block 136 in clamping the rotating shaft 140, preventing the rotating shaft 140 from rotating relative to the first clamping block 135 and the second clamping block 136, and the bolt connection facilitates disassembly and maintenance.

[0033] In one possible implementation, the rotating mechanism 100 further includes a limiting block 150, and the mounting bracket 110 is provided with a limiting screw 112. The limiting block 150 is connected to the rotating shaft 140, and the rotating shaft 140 can drive the limiting block 150 to rotate synchronously during rotation. The limiting screw 112 is used to abut against the limiting block 150 to limit the extreme position of the rotation of the rotating shaft 140, thereby limiting the extreme position of the rotation of the object to be rotated 200 and ensuring the rotation accuracy of the object to be rotated 200.

[0034] Furthermore, there are two limiting screws 112, both of which abut against the limiting block 150 to limit the extreme positions of the rotating shaft 140 in two opposite directions, thereby limiting the maximum rotation angle of the rotating shaft 140, and consequently limiting the maximum rotation angle of the object to be rotated 200. In this embodiment, the maximum rotation angle of the rotating shaft 140 is 90 degrees, but it is not limited to this. In other embodiments, the maximum rotation angle of the rotating shaft 140 can be 60 degrees or 120 degrees; the maximum rotation angle of the rotating shaft 140 is not specifically limited.

[0035] As one possible implementation, the rotating mechanism 100 also includes a buffer 160. The buffer 160 is mounted on the mounting bracket 110, and the position of the buffer 160 corresponds to the position of the limit screw 112. The buffer 160 is used to buffer the limit block 150 before the limit block 150 abuts against the limit screw 112, so as to realize the buffering and shock absorption function, prevent the vibration rebound caused by the rigid collision between the limit block 150 and the limit screw 112, and extend the service life.

[0036] The mounting bracket 110 includes a main body 113 and an extension 114 connected to each other. The extension 114 is arranged perpendicular to the main body 113, and a telescopic drive member 120 is rotatably mounted on the main body 113, i.e., a positioning pin 111 is provided on the main body 113, and the rotating block 121 of the telescopic drive member 120 is rotatably engaged with the positioning pin 111. The extension 114 has a limiting hole 115, through which a rotating shaft 140 passes and can rotate relative to the extension 114. The extension 114 can limit the rotation of the rotating shaft 140 to ensure the stability of the rotation of the rotating shaft 140.

[0037] Furthermore, there are two extensions 114, which are arranged in parallel and spaced apart. The rotating shaft 140 passes through the limiting holes 115 of both extensions 114. The two extensions 114 work together to further improve the limiting effect on the rotating shaft 140 and improve the stability of the rotation of the rotating shaft 140. In this embodiment, the limiting block 150 is disposed between the two extensions 114. The two extensions 114 work together to limit the limiting block 150 and prevent the limiting block 150 from disengaging from the rotating shaft 140.

[0038] This utility model embodiment also provides a vibration testing device (not shown in the figure), including the aforementioned rotating mechanism 100, wherein the object to be rotated 200 is a relay, and the rotating mechanism 100 can drive the relay to rotate to different angles to simulate the installation angle of the relay in different scenarios, facilitating vibration testing. Since the structure and beneficial effects of the rotating mechanism 100 have been described in detail in the foregoing embodiments, they will not be repeated here.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
