Description

Technical Field

[0001] This utility model relates to the field of chemical teaching instrument cleaning technology, and in particular to a chemical teaching instrument cleaning device. Background Technology

[0002] Cleaning chemical teaching instruments is a very important part of chemical experiments, as it directly affects the accuracy of experimental results and the lifespan of the instruments.

[0003] Therefore, a chemical teaching instrument cleaning device in the prior art, with publication number CN221734348U, includes a placement component for fixing chemical containers. The placement component comprises two semicircular blocks, with the two semicircular blocks located on one side of the inner wall of the cleaning body. A base block is installed on one side of each semicircular block, and a fastening bolt is threaded through the interior of each semicircular block. A movable block is installed on the outer side of the fastening bolt, located on one side of each semicircular block. A frame is installed on one side of each of the two movable blocks, with an opening on each side of the frame. A screw block is installed inside each opening, and a box is installed between the two screw blocks. The box has four small partitions installed on its inner side, and five sets of rubber blocks are installed on the inner walls of both sides of the box, with two rubber blocks per set. A cross is installed between the bottom of the box and the small partitions. When the staff needs to use the chemical teaching instrument cleaning device, the staff loosens the fastening bolts, places the frame in a horizontal position, and then tightens the fastening bolts. The staff places the chemical container upside down inside the box, so that the chemical container is placed on top of the cross, moves the box to the appropriate position, and tightens the nuts to fix the box. The staff then turns on the ultrasonic control body through the controller and starts the cleaning machine to perform the cleaning work.

[0004] However, because the semicircular block is located on one side of the inner wall of the cleaning machine, its installation height within the machine is fixed. This results in a fixed distance between the box and the upper surface of the machine in a horizontal state, as well as a fixed distance between the two rubber blocks. Therefore, when cleaning instruments of different sizes, i.e., when the placed instrument does not contact the two rubber pads and the height of the instrument is less than the height of the box and the top of the machine, the instrument is prone to shaking due to the water flow during the cleaning process. This can easily cause the instrument to detach from the box and fall, resulting in damage to the instrument. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a chemical teaching instrument cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical teaching instrument cleaning device, comprising a cleaning box, wherein a plurality of placement boxes are arranged inside the cleaning box, and a plurality of elastic clamping mechanisms arranged side by side are arranged on the placement boxes. Each elastic clamping mechanism includes two symmetrically arranged sockets that are respectively inserted into the outer walls of the two sides of the placement boxes. A swing plate is hinged to the socket by a torsion spring. The top of the swing plate is set higher than the top of the placement box and is fixedly installed with an anti-slip paddle for conforming to the surface of the instrument. Swing rods are arranged on both sides of the top of the placement box. The swing rods are used to push the plurality of swing plates arranged on the same side, and guide frames and auxiliary frames are sleeved at both ends of the swing rods. The guide frames and auxiliary frames are concentric and have the same curvature. The guide frames are fixed to the surface of the placement boxes, and the center of the auxiliary frames is hinged to the placement boxes by a torsion spring.

[0007] Preferably, a swing arm is hinged to the outer wall of the placement box near any auxiliary frame via a torsion spring, a lever is hinged to the top of the swing arm, and a connecting rod is fixedly installed on the side of the lever near the swing arm.

[0008] Preferably, the outer side of the auxiliary frame extends outward and has a U-shaped groove, and one end of the connecting rod extends outward and is inserted into the inner wall of the U-shaped groove at an adjacent position.

[0009] Preferably, both ends of the placement box are provided with vertical rails that are vertically arranged and fixedly installed on the inner side wall of the cleaning box. The surface of the vertical rails is provided with a plurality of insertion holes from top to bottom. A spring rod is fixedly installed at the bottom of the placement box, and a plug is fixedly installed at the telescopic end of the spring rod to be inserted into the insertion hole.

[0010] Preferably, the surface of the spring rod extends upward and is connected to a connecting rope. One end of the connecting rope extends horizontally and passes through the surface of the spring rod cylinder. The end of the connecting rope passing through the spring rod is connected to the bottom end of the adjacent swing arm.

[0011] Preferably, the top of the swing arm is stepped, and the stepped surface of the top of the swing arm is hinged to the lever by a torsion spring.

[0012] Preferably, the anti-slip paddle has an arc-shaped side edge with a smooth transition at the edge.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, several swing plates are set on both sides of the placement box. The torsion spring between the swing plate and the socket provides the torsion force to make the swing plate swing towards the placement box. When placing the instrument, the instrument pushes the anti-slip plate to drive the swing plate to rotate against the torsion force of the torsion spring. After the instrument to be cleaned is placed upside down into the placement box, the torsion force of the torsion spring forces the swing plate to move closer to the instrument. The anti-slip plate on the swing plate is used to clamp the instrument against the surface of the instrument, which can prevent the instrument from shaking due to water during the cleaning process.

[0015] 2. In this utility model, when the lever swings towards the placement box, it drives the swing arm to swing. The bottom end of the swing arm pulls the connecting rope, and the connecting rope pulls the spring rod to retract elastically, which can realize the retraction of the insertion post and its removal from the insertion hole. Therefore, it is convenient for personnel to adjust the height of the placement box in the cleaning box according to the height of the instrument, ensuring that the instrument is completely submerged in the cleaning water in the cleaning box.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, the chemical teaching instrument cleaning device includes a cleaning box 1, inside which are several placement boxes 3. Several elastic clamping mechanisms are arranged side-by-side on each placement box 3. Each elastic clamping mechanism includes two symmetrically arranged sockets 8 that are respectively inserted into the outer walls of the placement boxes 3. A swing plate 4 is hinged to each socket 8 via a torsion spring. The top of the swing plate 4 is positioned above the top of the placement box 3 and is fixedly fitted with an anti-slip paddle 9 for adhering to the instrument surface. The anti-slip paddle 9 has rounded edges and smooth transitions. In use, the instrument to be cleaned is placed upside down into the placement box 3, and the torsion spring is used to... The torsion of the spring forces the swing plate 4 closer to the instrument, and the anti-slip tab 9 on the swing plate 4 clamps the instrument against its surface, preventing it from shaking due to water agitation during cleaning. Swing rods 16 are installed on both sides of the top of the placement box 3. These rods push several swing plates 4 on the same side, and guide frames 14 and auxiliary frames 13 are fitted at both ends of the rods. The guide frames 14 and auxiliary frames 13 are concentric and have the same curvature. The guide frames 14 are fixed to the surface of the placement box 3, and the center of the auxiliary frames 13 is hinged to the placement box 3 by a torsion spring. Figure 2 and Figure 3 The guide frames 14 at both ends of the swing rod 16 ensure that the swing rod 16 can only slide along the arc direction of the guide frame 14. When the two swing rods 16 slide in opposite directions along the inner wall of the corresponding guide frame 14, the swing rod 16 contacts and pushes several swing plates 4 on the same side to swing away from the top of the placement box 3. This allows the anti-slip paddle 9 to detach from the instrument surface, making it easier for personnel to remove the cleaned instrument from the placement box 3. In order to drive the swing rod 16 to swing, combined with Figure 3 The auxiliary frame 13 overcomes the torsion of the torsion spring and swings away from the placement box 3. The overlap between the end of the auxiliary frame 13 and the end of the swing rod 16 pushes the swing rod 16 to swing away from the placement box 3 within the guide frame 14.

[0024] To drive the elastic clamping mechanism to open: A swing arm 10 is hinged to any auxiliary frame 13 on the outer wall of the placement box 3 via a torsion spring. A lever 11 is hinged to the top of the swing arm 10. The top of the swing arm 10 is stepped, and the stepped portion of the top of the swing arm 10 is hinged to the lever 11 via a torsion spring. Figure 3 The torsion spring here ensures that the lever 11 and the swing arm 10 function normally. Figure 3As shown, the shape of the step ensures that when the lever 11 swings towards the placement box 3, the swing arm 10 swings towards the placement box 3 under the interference of the step surface; or when the lever 11 swings away from the placement box 3, the swing arm 10 will not swing. A connecting rod 12 is fixedly installed on the side of the lever 11 near the swing arm 10. The outer side of the auxiliary frame 13 extends outward and has a U-shaped groove 17. One end of the connecting rod 12 extends outward and is inserted into the inner wall of the adjacent U-shaped groove 17. When the lever 11 swings towards the placement box 3, it correspondingly drives the connecting rod 12 to swing towards the placement box 3. During the swing, the auxiliary frame 13 is pushed to swing towards the placement box 3 under the interference of the inner wall of the U-shaped groove 17, and combined with Figure 3 It can be seen that when the auxiliary frame 13 swings towards the placement box 3, the swing rod 16 will not swing; when the lever 11 swings away from the placement box 3, under the interference of the inner wall of the U-shaped groove 17, the connecting rod 12 can drive the auxiliary frame 13 to swing away from the placement box 3, and the auxiliary frame 13 can drive the swing rod 16 to swing along the inner wall of the guide frame 14 away from the placement box 3.

[0025] To facilitate adjustment of the installation height of the placement box 3: Vertical rails 2 are installed at both ends of the placement box 3, fixedly mounted on the inner wall of the cleaning box 1. Several insertion holes 5 are formed on the surface of the vertical rails 2 from top to bottom. A spring rod 7 is fixedly installed at the bottom of the placement box 3. A post 6, which inserts into the insertion hole 5, is fixedly installed at the telescopic end of the spring rod 7. A connecting rope 15 extends upwards from the surface of the telescopic spring rod 7. One end of the connecting rope 15 extends horizontally and passes through the surface of the spring rod 7 cylinder. The end of the connecting rope 15 passing through the spring rod 7 is connected to the bottom end of the adjacent swing arm 10. In actual use, combined with… Figure 3 and Figure 4 When the lever 11 swings towards the placement box 3, it drives the swing arm 10 to swing. The bottom end of the swing arm 10 pulls the connecting rope 15, and the connecting rope 15 pulls the spring rod 7 to retract elastically, so that the insertion post 6 can retract and move out of the insertion hole 5. Therefore, it is convenient for personnel to adjust the height of the placement box 3 in the cleaning box 1 according to the height of the instrument, and ensure that the instrument is completely submerged in the cleaning water in the cleaning box 1.

[0026] Working principle: When in use, press the two levers 11 at both ends of the placement box 3 to make the two levers 11 move closer to each other and swing towards the placement box 3. When the levers 11 swing towards the placement box 3, they drive the swing arm 10 to swing. The bottom end of the swing arm 10 pulls the connecting rope 15, and the connecting rope 15 pulls the spring rod 7 to retract elastically, so that the insertion post 6 can retract and move out of the insertion hole 5. Therefore, it is convenient for personnel to adjust the height of the placement box 3 in the cleaning box 1 according to the height of the instrument. After the adjustment is completed, the instrument is placed upside down in the placement box 3. The torsion of the torsion spring forces the swing plate 4 to move closer to the instrument, and the anti-slip plate 9 on the swing plate 4 is used to clamp the instrument by adhering to the surface of the instrument.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
