DETAILED DESCRIPTION

[0024] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0025] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0026] like Figure 1 and Figure 2As shown, it is a shock absorbing device for automation instruments of an embodiment of the utility model, the top of the support leg 1 is fixedly connected to the lower surface of the bottom plate 2, and the upper surface of the bottom plate 2 is fixedly connected to the bottom of the protection box 3. The inner wall of the protection box 3 is slidably connected to the side of the placement plate 10 (for example, by providing a sliding groove and a slide rail on the corresponding inner wall of the protection box 3, which is a common sliding matching structure in the art), so that the placement plate 10 can slide up and down relative to the protection box 3, so that the shock absorbing mechanism 9 under the placement plate 10 can reduce the shock of the placement plate 10 and the products thereon. There are two linkage frames 5, which are respectively located on opposite sides of the protection box 3. The lower part of the linkage frame 5 is located in the protection box 3 and connected to the power mechanism 4. The upper part of the linkage frame 5 extends from the top of the protection box 3 and is slidably connected to the placement plate 10. The upper part of the linkage frame 5 is connected to the first spring 6 and the clamping plate 7 in sequence toward the linkage frame 5 on the other side, so that the linkage frames 5 on both sides can be clamped or loosened relative to the product on the placement plate 10 under the drive of the power mechanism 4. At the same time, both sides of the placement plate 10 have notches for movably accommodating the linkage frame 5 to avoid the movement of the linkage frame 5. The upper surface of the bottom plate 2 is fixedly connected to the bottom of the buffer structure 8, the top of the buffer structure 8 is fixedly connected to the bottom of the shock absorbing mechanism 9, the top of the shock absorbing mechanism 9 is fixedly connected to the lower surface of the placement plate 10, the shock absorbing mechanism 9 is used to shock the placement plate 10, and the buffer structure 8 is used to buffer the shock absorbing mechanism 9, which can help further alleviate aftershocks. The bottom of the power mechanism 4 is fixedly connected to the upper surface of the bottom plate 2, and the power mechanism 4 is also connected to the linkage frames 5 on both sides, and can drive the linkage frames 5 on both sides to move toward or away from each other to form clamping or loosening. Through the above arrangement, the structure of the overall device is more compact, the coordination between the various components is smoother, and it is not easy to fail. At the same time, the automatic instrument can be effectively earthquake-resistant.

[0027] like Figure 3As shown, in this embodiment, the power mechanism 4 includes a motor 401, the output end of the motor 401 is connected to the first gear 402 and can drive the first gear 402 to rotate. The first gear 402 is meshed with a second gear 403 on one side, and the second gear 403 is fixedly connected to the middle of the central axis 404. A third gear 405 is connected to each end of the central axis 404, and a strip plate 406 cooperates with the third gear 405. Corresponding to a third gear 405 at each end of the central axis 404, there are also two groups of strip plates 406, which are respectively arranged on both sides of the inside of the protection box 3. Each group of strip plates 406 includes two strip plates 406 arranged up and down. There is a space between the two strip plates 406 on the same side of the protection box 3 for accommodating the corresponding third gear 405, and the two strip plates 406 on the same side have teeth on the surfaces facing each other for meshing with the third gear 405. Four guide rods 407 are provided corresponding to the four strip plates 406, one end of the guide rod 407 is connected to the corresponding strip plate 406, and the other end is connected to the linkage frame 5. At the same time, four support blocks 408 are provided on the bottom plate 2 corresponding to the guide rods 407, and the guide rods 407 are movably inserted into the support blocks 408. Through the above arrangement, the motor 401 drives the first gear 402 to rotate, which can drive the two third gears 405 to rotate. Since each third gear 405 has a meshing strip plate 406 above and below, the third gear 405 drives the two strip plates 406 above and below to move toward or away from each other, and then drives the linkage frames 5 on both sides to move toward or away from each other through the guide rods 407. Figure 6 As shown, the bottom plate 2 is also provided with a limit frame 11 for limiting the strip plate 406 to move only in the horizontal direction, thereby ensuring that the linkage frame 5 also moves only in the horizontal direction. Therefore, the shock absorbing device of this embodiment is an automatic power device, which can save more labor and can freely control the specifications of the installed instruments, making the device more practical and less likely to have a single function. It can be used in more work scenes. At the same time, when the automatic instrument is clamped and fixed, the process is smoother, and it is ensured that the movement trajectory of the components will not deviate from the established route during the movement process, making the overall device more stable, thereby extending the working time.

[0028] like Figure 4As shown, in this embodiment, the shock absorbing mechanism 9 includes a balance plate 901, and the upper surface of the balance plate 901 is fixedly connected to the bottom of the blocking plate 902. There are two blocking plates 902, which are respectively located on both sides of the balance plate 901, and the two blocking plates 902 are fixedly connected by a track rod 903. A special-shaped slider 904 is slidably arranged on the track rod 903, and there are also two special-shaped sliders 904. Each special-shaped slider 904 is connected to its corresponding blocking plate 902 through a third spring 905. The bottom of the special-shaped slider 904 is slidably connected to the limiting groove on the upper surface of the balance plate 901 (used to control the special-shaped slider 904 to move along a predetermined route on the balance plate 901), thereby preventing the special-shaped slider 904 from deviating from the track, ensuring that the overall device will not fail, and ensuring the correct installation and shock absorption of the instrument. There can be several track rods 903 to ensure the stability of the whole device and the coordination between the components, so that the components will not be damaged due to long-term use, and the service life of the device will be increased; at the same time, the third spring 905 also has multiple groups corresponding to the multiple track rods 903 (it is easy to understand that there is a third spring 905 between the two groups of baffles 902 and the special-shaped slider 904 on the same track rod 903, so the number of third springs 905 is twice the number of track rods 903), so as to achieve more uniform and comprehensive shock absorption between the special-shaped slider 904 and the baffle 902, so as to alleviate the vibration caused by the operation of the instrument to the greatest extent, ensure the stability of the device and the pressure it receives during the shock absorption process, and ensure the overall operation of the device. The top of the special-shaped slider 904 has several bearing grooves, which are used to be rotatably connected to the support bearing 906, and the support bearing 906 is rotatably connected with an adjustment rod, and the other end of the adjustment rod is rotatably connected to the groove on the side of the support plate 907 (for example, also through a bearing). The bottom of the support plate 907 is fixedly connected to one end of the hydraulic rod 908, the other end of the hydraulic rod 908 is fixedly connected to the upper surface of the balance plate 901, the hydraulic rod 908 is sleeved with a fourth spring 909, and the two ends of the fourth spring 909 are respectively fixedly connected to the balance plate 901 and the support plate 907. By providing a preliminary pressure buffer for the instrument already placed in the device due to its own weight, the height of the instrument installation is ensured to be consistent, and the instrument can operate normally in subsequent work.

[0029] like Figure 5 As shown, in this embodiment, the buffer structure 8 includes a sleeve 801, the inner wall of the sleeve 801 is slidably provided with a slide 802, the top of the sleeve 801 is fixedly connected to the 901 balance plate of the shock absorbing mechanism, the bottom of the slide 802 is fixedly connected to one end of the second spring 803, and the other end of the second spring 803 is fixedly connected to the upper surface of the bottom plate 2. It plays a role in buffering the vibration generated by the work of the automation instrument, effectively relieves the aftershock, and is also an important pillar to ensure the stability of the overall device.

[0030] The shock absorbing device of this embodiment works as follows:

[0031] First, place the instrument to be installed on the placement plate 10, then start the motor 401 to drive the first gear 402 to rotate, so that the second gear 403 meshing with the first gear 402 rotates, drives the middle shaft 404 to rotate, and makes the third gear 405 rotate in the strip plate 406, so that the strip plate 406 moves horizontally under the limit of the limit frame 11, ensuring that the strip plate 406 is tightly combined with the third gear 405, preventing the strip plate 406 from deviating from the established route during the movement, and driving the clamping plate 7 on the linkage frame 5 to act on the first spring 6 The instrument is buffered and fixed at the bottom, which makes it convenient for the staff to install and replace the instrument more quickly. At the same time, instruments of different sizes can be installed to increase the practicality of the device. When the instrument vibrates due to work, the force borne by the support bearing 906 is transmitted to the special-shaped slider 904, so that the special-shaped slider 904 moves horizontally on the track rod 903, squeezing the third spring 905. Due to the elastic characteristics of the third spring 905 itself, the jitter can be effectively buffered, ensuring that the position of the instrument is not offset and can operate normally.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
