[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] Embodiment 1:

[0031] like Figure 1 to Figure 5 As shown, a pendulum-type rocking bed for experiments comprises a main box body 1, support rods 2 are respectively provided on both sides of the upper part of the main box body 1, a pair of the support rods 2 are connected with a swingable support bed board 3, and a loading tray 4 is detachably connected to the upper part of the support bed board 3; a first slider 5 is provided on the lower side of the support bed board 3, and a connecting rod 6 is rotatably connected to the lower part of the first slider 5, and the connecting rod 6 extends into the main box body 1 and is connected with a slide rod 7, and a second slider 9 is provided in the slide groove 8 of the slide rod; a driving motor is also connected to the main box body 1 through a support seat 10, and an output shaft 11 of the driving motor is connected with a swing arm 12, and the swing arm 12 is arranged perpendicular to the axis of the output shaft 11, and the other end of the swing arm 12 is rotatably connected to the second slider 9.

[0032] The pendulum shaker used in this experiment improves the installation method and driving method of the supporting bed plate 3, which can make the supporting bed plate 3 swing back and forth regularly and periodically, thereby driving the loading tray 4 thereon to swing regularly, and can well oscillate and mix drugs, reagents, etc.; and the pendulum shaker has a relatively simple structure and a low manufacturing cost, which can reduce the overall cost, and the accessories are easy to replace and maintain, which is suitable for daily use in the laboratory.

[0033] The driving motor and the slide rod 7 are both installed in the main box 1. When the driving motor is started, the swing arm 12 can be driven to perform circular motion, that is, the second slider 9 can be driven to perform circular motion. Due to the existence of the slide groove of the slide rod, the circular motion trajectory of the second slider 9 can drive the slide rod 7 to move in a directional manner, that is, drive the slide rod 7 to perform reciprocating lifting motion, thereby driving the connecting rod 6 to perform directional reciprocating lifting motion. With the cooperation of the first slider 5, the left and right swing of the supporting bed board 3 can be achieved. This connection driving method can well convert the rotational motion of the driving motor into the reciprocating lifting motion of the connecting rod 6, and then into the reciprocating swing of the supporting bed board 3. In this process, it is only necessary to control the speed and continuous rotation time of the driving motor, so as to conveniently control the swing frequency and duration of the supporting bed board, without the need for the motor to frequently perform forward and reverse motions in order to achieve reciprocating motion.

[0034] The loading tray 4 is detachable, and can be replaced with loading trays of different styles according to the types of processed objects, which is also convenient for cleaning the loading tray after the test.

[0035] Furthermore, the connecting rod 6 is arranged vertically, and the slide slot rod 7 is arranged horizontally, that is, the two are arranged vertically at 90 degrees; the connecting rod 6 is connected to the middle part of the slide slot rod 7, and the connecting rod 6 and the slide slot rod 7 are an integrated structure, and such a setting has high structural stability.

[0036] Under this connection structure, the slide groove in the slide groove rod 7 is symmetrical with the central axis (output shaft) of the swing arm 12. No matter the swing arm 12 drives the second slider 9 to rotate on the left or the right, the moving speeds of the slide groove rod 7 and the connecting rod 6 are balanced, so that the left and right swinging speeds and amplitudes of the supporting bed board 3 and the loading tray 4 are also the same.

[0037] Furthermore, the inner wall of the main box body 1 is also connected to a vertically arranged guide block 13 through a connecting piece, and a vertical guide groove is provided on the guide block 13, and the connecting rod 6 slides through the vertical guide groove.

[0038] The guide block 13 plays a guiding and limiting role, which can constrain the connecting rod 6 to maintain vertical movement, and can improve the stability of the movement of the connecting rod 6. The guide block 13 remains stationary, and the vertical guide groove and the connecting rod are slidably matched, which does not affect the reciprocating lifting and lowering movement of the connecting rod.

[0039] Furthermore, ear plate structures 15 are provided on both sides of the support bed board 3, and the ear plate structures 15 are connected to the support rod 2 through a rotating shaft. With this connection mode, the support bed board 3 can be rotated and flipped. The rotating shaft can be a short shaft connected to the side, or a long shaft connected to the ear plate structures on both sides.

[0040] Furthermore, a first slide groove 14 is provided at the bottom of the supporting bed board 3, and the first slider 5 is slidably connected in the first slide groove 14. A pair of connecting ears 501 are provided on both sides below the first slider 5, and the connecting ears 501 are connected to the end of the connecting rod 6 through a hinge shaft.

[0041] During the lifting and lowering of the connecting rod 6, when the supporting bed board 3 swings, the supporting bed board 3 will tilt, and the supporting point positions of the connecting rod 6 and the supporting bed board 3 will be displaced. The hinged connection of the first slider 5 and the connecting ear can ensure the realization of movement. The first slide groove and the first slider can also be moved in the form of a slide rail.

[0042] In some embodiments, in combination Figure 5 As shown in FIG. 6 , a plurality of positioning pins 18 are provided below the cargo tray 4 , and a plurality of positioning holes 19 are provided on the supporting bed board 3 , and the positioning pins 18 are inserted into the positioning holes 19 .

[0043] The positioning pin 18 and the positioning hole 19 are used to connect the loading tray 4 and the supporting bed board 3, which is not only simple in structure but also convenient to use. Since the supporting bed board 3 and the loading tray 4 swing left and right, and the swing amplitude is not large, the positioning pin can completely limit the left and right positions, and the two will move synchronously without separation.

[0044] According to the setting of the length of the connecting rod, the inclination angle of the supporting bed board can be controlled within a range of -20° to 20°, usually swinging around 10°, and the length of the connecting rod at this time can be calculated based on the geometric relationship. After determining the swing amplitude of each rocking bed, the length of the connecting rod is a fixed value.

[0045] In other embodiments, the connecting rod may also be configured as a telescopic connecting rod, in which case the swing amplitude of the supporting bed board may be changed according to the length of the telescopic connecting rod, that is, this type of rocking bed has an adjustable swing amplitude.

[0046] In some embodiments, Figure 7 As shown, the cargo tray 4 is a metal tray having a flange 401 . The edges of the flange 401 are respectively provided with a plurality of U-shaped grooves 20 . The U-shaped grooves 20 are connected with detachable elastic binding belts 21 .

[0047] By using the elastic binding belt 21 and the U-shaped groove 20, the items placed on the loading tray 4 can be bound to prevent the items from sliding relative to the loading tray, so as not to affect the shaking and mixing of the reagents or drugs in the items.

[0048] In some embodiments, Figure 8 As shown, the loading tray 4 is a plastic tray, and a plurality of anti-skid protrusions 22 are arranged in an array on its inner surface. The anti-skid protrusions 22 can be plastic protrusions or silicone protrusions. The friction force of the protrusions is used to fix the carried items to reduce their relative sliding.

[0049] Furthermore, a controller is also provided in the main box 1, and the drive motor is electrically connected to the controller. A plurality of display screens 16 and adjustment knobs 17 are also provided on the front of the main box, and the adjustment knobs 17 and the display screens 16 are also electrically connected to the controller, respectively. The above arrangement facilitates the speed and time control of the drive motor.

[0050] The driving motor can be a stepping motor or a permanent magnet motor with an encoder, which has a fast response speed and controllable performance. The display screen can display the speed and time, and the adjustment knob can be a speed adjustment knob and a timing knob, so that the experimenter can adjust the speed and time.

[0051] Embodiment 2:

[0052] The difference between this embodiment and the first embodiment is that another structure of a connecting rod and a sliding groove rod is provided.

[0053] Specifically, Fig. 9 As shown, the connecting rod 6 is still arranged vertically, but the slide slot rod 7 is arranged obliquely, for example, the angle between the two is 80°; the connecting rod 6 is connected to the middle part of the slide slot rod 7, and the connecting rod 6 and the slide slot rod 7 are an integral structure.

[0054] Since the slide rod 7 is arranged at an angle and its slide is angled, the extension speed of the left and right sides of the second sliding block 9 is not symmetrical when rotating, so that the swing amplitude of the supporting bed board 3 on the left and right sides is inconsistent. Through this differentiated setting, the mixing of certain drugs or reagents can be accelerated.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
