DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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.

[0019] See also Figure 1-4 The utility model provides a technical solution, an experimental tray with easily adjustable internal space, comprising a tray body 1 and an extension mechanism 3, a lifting mechanism 2 is arranged on one side of the surface of the tray body 1, and an extension mechanism 3 is arranged on one side of the surface of the tray body 1;

[0020] The extension mechanism 3 includes a pull plate 301, a clamping hole 302, a limiting groove 303, a pressure strip 304, a spring 305, a limiting block 306, a second support plate 307, a second through hole 308 and a clamping block 309. The pull plate 301 is embedded on one side of the surface of the tray body 1, the clamping hole 302 is provided inside the tray body 1, the limiting groove 303 is provided on one side of the surface of the pull plate 301, the pressure strip 304 is provided inside the pull plate 301, and the inner The spring 305 is provided at the bottom, the limiting block 306 is embedded in the limiting groove 303, the limiting block 306 is fixedly connected to the second supporting plate 307, the second supporting plate 307 has a second through hole 308 on one side of the surface, and the clamping block 309 is fixedly connected to one side of the surface of the pressure strip 304. When the clamping block 309 is in the position of the second set of clamping holes 302, the spring 305 is not subjected to external force and begins to return to the original position, thereby the spring 305 drives the clamping block 309 to return to the original position, thereby making the clamping block 309 engage with the clamping hole 302. In this process, the pull plate 301 drives the limit block 306 to move, and the limit block 306 drives the second supporting plate 307 to move, thereby making the second supporting plate 307 drive the second through hole 308 to be exposed, thereby achieving the purpose of increasing the number of through holes and facilitating the placement of more experimental test tubes.

[0021] Furthermore, one end of the spring 305 is fixedly connected to the pull plate 301, and the other end of the spring 305 is fixedly connected to the pressure strip 304. The block 309 passes through the pull plate 301. Through the setting of the spring 305, when in use, the spring 305 will shrink and deform when squeezed. When the squeezing force disappears, the spring 305 will reset due to its own characteristics, so that the spring 305 can provide power for the reset movement of the pressure strip 304.

[0022] Furthermore, two groups of card holes 302 are provided, and the card holes 302 are engaged with the card blocks 309. The pressure strip 304 is made of elastic material. Through the setting of the pressure strip 304, when in use, the pressure strip 304 can provide support for the card block 309, and at the same time, the pressure strip 304 can drive the card block 309 to engage or disengage from the card hole 302 when it moves.

[0023] Furthermore, the lifting mechanism 2 includes a rotating key 201, a screw rod 202, a slider 203, a first support plate 204 and a first through hole 205. The rotating key 201 is installed on one side of the surface of the tray body 1, the screw rod 202 is connected to one side of the surface of the rotating key 201, the slider 203 is threadedly connected to one side of the surface of the screw rod 202, the slider 203 is connected to one side of the surface of the first support plate 204, and the first through hole 205 is opened on one side of the surface of the first support plate 204. By setting the rotating key 201, the screw rod 202, the slider 203, the first support plate 204 and the first through hole 205, when in use, when it is necessary to adapt to experimental test pieces of different lengths. When placing the tube, first rotate the rotation key 201, so that the rotation key 201 drives the screw rod 202 to rotate. Since the slider 203 is restricted by the first support plate 204 and cannot rotate, the screw rod 202 drives the slider 203 to move along the direction of the screw rod 202, and the slider 203 drives the first support plate 204 to move, and the first support plate 204 drives the first through hole 205 to move. At the same time, the first support plate 204 drives the second support plate 307 to move, and the second support plate 307 drives the second through hole 308 to move, thereby achieving the purpose of adjusting the height of the first through hole 205 and the second through hole 308, thereby meeting the stable placement requirements of experimental test tubes of different lengths.

[0024] Furthermore, the first through holes 205 are distributed at equal intervals, and the positions of the first through holes 205 and the second through holes 308 correspond to each other. Through the setting of the first through holes 205, when in use, the first through holes 205 can engage the experimental test tubes, so that the first through holes 205 and the tray body 1 cooperate with each other to achieve the purpose of placing the experimental test tubes.

[0025] Furthermore, the first support plate 204 is engaged with the second support plate 307, and the spacing of the first through holes 205 is equal to the spacing of the card holes 302. Through the setting of the first support plate 204, when in use, the first support plate 204 can provide support for the second support plate 307, and at the same time, the first support plate 204 can limit the position of the slider 203, thereby preventing the slider 203 from rotating.

[0026] Working principle: First, press the pressure strip 304, at this time, the pressure strip 304 squeezes the spring 305 to contract, and at the same time, the pressure strip 304 drives the block 309 to disengage from the hole 302, and then pull the pull plate 301, and then release the pressure strip 304, so that the pull plate 301 drives the pressure strip 304 to move, and the pressure strip 304 drives the block 309 to move, when the block 309 moves to the position of the second group of holes 302, the spring 305 is not subject to external force and starts to reset, so that the spring 305 drives the pressure strip 304 to reset, and the pressure strip 304 drives the block 309 to reset, so that the block 309 is engaged with the hole 302, in this process, the pull plate 301 drives the limit block 306 to move, and the limit block 306 drives the second support plate 307 to move, so that the second support plate 307 drives the second through hole 302 08 is exposed, thereby achieving the purpose of increasing the number of through holes and facilitating the placement of more experimental test tubes. When it is necessary to accommodate the placement of experimental test tubes of different lengths, first rotate the rotation key 201, so that the rotation key 201 drives the screw rod 202 to rotate. Since the slider 203 is restricted by the first support plate 204 and cannot rotate, the screw rod 202 drives the slider 203 to move along the direction of the screw rod 202, the slider 203 drives the first support plate 204 to move, the first support plate 204 drives the first through hole 205 to move, and at the same time the first support plate 204 drives the second support plate 307 to move, so that the second support plate 307 drives the second through hole 308 to move, thereby achieving the purpose of adjusting the height of the first through hole 205 and the second through hole 308, thereby meeting the stable placement requirements of experimental test tubes of different lengths.

[0027] 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.
