Description

Technical fields:

[0001] This utility model relates to the field of observation technology, specifically to a heating platform observation mechanism. Background technology:

[0002] When digesting soil, the crushed soil is first added to a beaker, and then the test solution is added to the beaker. Multiple beakers containing soil and test solution are placed on a heating platform, which heats the materials in the beakers. The liquid in the beakers is prone to splashing out. An exhaust system is installed directly above the heating platform to extract the gas generated during heating. The staff regularly observes the changes in the materials in the beakers from directly above.

[0003] Currently, when observing the liquid inside the beaker, staff can only periodically observe the changes in the material inside the beaker from directly above. However, due to the beaker being located deep within the heating platform, observation is inconvenient, requiring staff to bend over and stick their heads inside. The heated liquid inside the beaker is prone to splashing and scalding staff, making observation difficult. Utility model content:

[0004] Therefore, the purpose of this utility model is to provide a heating platform observation mechanism to overcome the problems of existing technology, which currently requires staff to periodically observe changes in the material in the beaker from directly above, and because the beaker is located deep within the heating platform, it is inconvenient to observe, requiring staff to bend over and stick their heads in for observation. Furthermore, the heated liquid in the beaker is prone to splashing and scalding staff, making observation difficult.

[0005] This utility model is implemented by the following technical solution:

[0006] A heating platform observation mechanism includes a support frame fixed to the side wall of the heating platform. The side wall of the support frame has a through groove, and an L-shaped tube is slidably fitted inside the through groove. A convex mirror is fixedly connected at the connection between the horizontal and vertical inner walls of the L-shaped tube. A groove is formed on the top surface of the horizontal tube of the L-shaped tube. A positioning component is fixedly connected to the top surface of the support frame. Multiple protrusions are horizontally fixedly connected to the output end of the positioning component. The output end of the positioning component can drive the protrusions to be inserted into the groove to position the L-shaped tube.

[0007] Preferably, the horizontal and vertical sections of the L-shaped tube are both square.

[0008] Preferably, the shortest distance between two adjacent convex strips is greater than the width of the L-shaped tube.

[0009] Preferably, the positioning component includes a slide groove, the bottom end of which communicates with a through groove, a slide rod that is slidably fitted inside the slide groove, the bottom surface of the slide rod being fixedly connected to a protrusion, and a plurality of first compression springs being fixedly connected between the top surface of the slide rod and the support frame, the first compression springs being disposed in the slide groove.

[0010] Preferably, the top surface of the L-shaped tube has multiple connecting rods symmetrically arranged. One end of the horizontal bar of each connecting rod is fixedly connected to a sliding rod, which is slidably disposed in a groove. The vertical bar of each connecting rod passes through the L-shaped tube and into a dovetail groove, and is fixedly connected to the top surface of a dovetail block. The dovetail groove is located on the side wall of the L-shaped tube. The dovetail block is slidably disposed in the dovetail groove. A second compression spring is fixedly connected between the bottom surface of the dovetail block and the L-shaped tube. The second compression spring is disposed in the dovetail groove, and its elastic force is much smaller than that of the first compression spring. The vertical bar of the connecting rod is slidably connected to the L-shaped tube. Rake teeth are fixedly connected to the side walls of the multiple dovetail grooves. The teeth at the top of each rake tooth are fixedly connected to a protrusion. The distance between adjacent teeth at the top of each rake tooth is equal to the width of the support frame. The support frame is disposed between two adjacent teeth at the top of each rake tooth.

[0011] Preferably, the protrusion is hemispherical in shape.

[0012] The advantages of this invention are as follows: A support frame is fixedly connected to the side wall of the heating platform, and an L-shaped tube is slidably installed in the through groove inside the support frame. A convex mirror is fixedly connected inside the L-shaped tube. By sliding the L-shaped tube, the convex mirror can be moved. The operator can observe the changes in the liquid inside the beaker from directly above through the convex mirror via the horizontal tube of the L-shaped tube. This effectively reduces the risk of scalding the operator from splashing liquid and facilitates the operator's observation of the liquid inside the beaker. Attached image description:

Detailed implementation method:

[0022] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1-7As shown, this utility model provides the following technical solution: a heating platform observation mechanism, including a support frame 1 fixed to the side wall of the heating platform, a through groove 2 opened on the side wall of the support frame 1, an L-shaped tube 7 slidably disposed in the through groove 2, a convex mirror 8 fixedly connected at the connection between the horizontal tube and the inner wall of the vertical tube of the L-shaped tube 7, a groove 9 opened on the top surface of the horizontal tube of the L-shaped tube 7, a positioning component fixedly connected to the top surface of the support frame 1, a plurality of protrusions 6 horizontally fixedly connected to the output end of the positioning component, the output end of the positioning component can drive the protrusions 6 to be inserted into the groove 9 to position the L-shaped tube 7.

[0027] Please combine Figure 1 As shown, during the process of soil digestion, the crushed soil is first added to a beaker, followed by the detection liquid. Multiple beakers containing soil and detection liquid are placed on a heating platform, which heats the materials. The liquid in the beaker is prone to splashing out, so an exhaust system is located directly above the heating platform to extract the gases generated during heating. The operator periodically observes the changes in the materials in the beakers from directly above. To observe these changes, the operator slides the L-shaped tube 7 left and right. The movement of the L-shaped tube 7 pushes the convex strip 6, which in turn activates the positioning component. The L-shaped tube 7 then moves the convex mirror 8 to the desired position. Below the corresponding row of beakers, the L-shaped tube 7 moves the groove 9. When the groove 9 is directly below the corresponding convex strip 6, the positioning component moves the convex strip 6 into the groove 9 to position the L-shaped tube 7. At this time, the L-shaped tube 7 stops the row of beakers below the convex strip 6. Then, the L-shaped tube 7 is moved forward and backward or backward to be directly below the beaker to be observed. The L-shaped tube 7 moves the groove 9 to slide on the convex strip 6. Then, the staff observes the changes in the solution in the corresponding beaker through the horizontal tube of the L-shaped tube 7 and the convex mirror 8. This effectively reduces the risk of scalding the staff from splashing liquid and facilitates the staff's observation of the liquid in the beaker. The convex strip 6 has an arc-shaped cross-section, which facilitates the longitudinal movement of the convex strip 6 by the L-shaped tube 7.

[0028] The horizontal and vertical sections of the L-shaped tube 7 are both square, which limits the L-shaped tube 7 in the through groove 2 and prevents the L-shaped tube 7 from rotating in the through groove 2.

[0029] The shortest distance between two adjacent protrusions 6 is greater than the width of the L-shaped tube 7, which facilitates the sliding of the L-shaped tube 7 and prevents the two adjacent protrusions 6 from jamming the L-shaped tube 7.

[0030] Please combine Figure 1 As shown in the embodiment of the positioning component, the positioning component includes a slide groove 3, the bottom end of the slide groove 3 is connected to the through groove 2, a slide rod 4 is slidably disposed in the slide groove 3, the bottom surface of the slide rod 4 is fixedly connected to the protrusion 6, and a plurality of first compression springs 5 ​​are fixedly connected between the top surface of the slide rod 4 and the support frame 1, and the first compression springs 5 ​​are disposed in the slide groove 3.

[0031] Please combine Figure 1 As shown, during use, when the L-shaped tube 7 moves laterally, the L-shaped tube 7 pushes the protrusion 6 to move longitudinally. The protrusion 6 drives the slide bar 4 to move and compress the first compression spring 5 to deform. When the protrusion 6 corresponds to the groove 9, the deformed first compression spring 5 pushes the slide bar 4 to move. The slide bar 4 drives the protrusion 6 to move and insert into the groove 9 to position the L-shaped tube 7.

[0032] Multiple connecting rods 12 are symmetrically arranged on the top surface of the L-shaped tube 7. One end of the horizontal bar of the multiple connecting rods 12 is fixedly connected to a sliding rod 10. The sliding rod 10 is slidably arranged in the groove 9. The vertical bar of the connecting rod 12 passes through the L-shaped tube 7 and enters the dovetail groove 13 and is fixedly connected to the top surface of the dovetail block 14. The dovetail groove 13 is opened on the side wall of the L-shaped tube 7. The dovetail block 14 is slidably arranged in the dovetail groove 13. A second compression spring 15 is fixedly connected between the bottom surface of the dovetail block 14 and the L-shaped tube 7. The second compression spring 15 is arranged in the dovetail groove 13 and the elastic force of the second compression spring 15 is much smaller than the elastic force of the first compression spring 5. The vertical bar of the connecting rod 12 is slidably connected to the L-shaped tube 7. Rake teeth 16 are fixedly connected to the side wall of the multiple dovetail grooves 13. The teeth at the top of the rake teeth 16 are fixedly connected to a protrusion 17. The distance between adjacent teeth at the top of the rake teeth 16 is equal to the width of the support frame 1. The support frame 1 is arranged between two adjacent teeth at the top of the rake teeth 16.

[0033] Please combine Figure 1As shown, during use, when the L-shaped tube 7 moves laterally, the support frame 1 limits the two adjacent teeth at the top of the rake tooth 16, preventing the rake tooth 16 from moving laterally forward, backward, or backward. The inability of the rake tooth 16 to move prevents the dovetail block 14 from moving forward, backward, or backward, thus limiting the forward, backward, or backward movement of the L-shaped tube 7. When the L-shaped tube 7 moves the groove 9 directly below the corresponding protrusion 6, the first compression spring 5, through the slide rod 4, drives the protrusion 6 into the groove 9, pushing the slide rod 10 to move. The slide rod 10 then moves the dovetail block 14, compressing the second compression spring 15 and causing it to deform. The dovetail block 14 then moves the rake tooth 16, gradually separating it from the side wall of the support frame 1. The support frame 1 then removes its limitation on the rake tooth 16, causing the rake tooth 16 to move downward a certain distance. The protrusion 17 no longer separates from the side wall of the support frame 1, thus achieving the limitation of the rake tooth 1 by the support frame 1. The limit switch 17 prevents unauthorized movement of the protrusion 17. Then, the L-shaped tube 7 moves forward and backward or backward. The L-shaped tube 7 moves the convex mirror 8, which in turn moves the dovetail groove 13 forward and backward or backward. The dovetail groove 13 moves the dovetail block 14 forward and backward or backward, which in turn moves the rake teeth 16. The rake teeth 16 then move the protrusion 17 forward and backward or backward. The support frame 1 pushes the protrusion 17 to move longitudinally, and the protrusion 17 moves the rake teeth 16. When the rake teeth 16 move, they drive the dovetail block 14 to move and compress the second compression spring 15, causing it to deform. When the vertical tube of the L-shaped tube 7 moves directly below the beaker to be observed, the deformed second compression spring 15 pushes the dovetail block 14 to move. The dovetail block 14 then drives the rake teeth 16 to move, and the rake teeth 16 drive the protrusion 17 to move and lock it against the side wall of the support frame 1 again. This achieves the front and rear limit of the L-shaped tube 7 by the support frame 1, preventing the L-shaped tube 7 from moving without human intervention and facilitating observation by staff.

[0034] When the L-shaped tube 7 moves the groove 9 and no longer corresponds to the convex strip 6, the convex strip 6 removes its limiting effect on the slide rod 10. The second compression spring 15 indirectly pushes the rake tooth 16 upwards to fit against the side wall of the support frame 1, thus limiting the rake tooth 16 and preventing it from moving forward, backward, or rearward. This indirectly limits the L-shaped tube 7, preventing it from moving forward, backward, or rearward. Figure 6 Figure 7 As shown.

[0035] The protrusion 17 is hemispherical in shape, which makes it easier for the support frame 1 to push the protrusion 17 to move downward.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
