Description

Technical Field

[0001] The utility model relates to the technical field of instrument drying, in particular to an oven device for experimental instruments. Background Technique

[0002] An oven, also called a drying oven, is a device used for drying items. It is generally made of section steel and thin plates by welding, which is firm and durable. There is a heat-insulating layer with good heat insulation between the working chamber of the drying oven and the box body shell, and a blower device is equipped, which can make the heated air in the working chamber forced convection, improving the temperature uniformity performance in the box.

[0003] According to the drying method, it can be divided into nitrogen-filled drying ovens, electrothermal blast drying ovens, hot air circulation drying ovens, etc. It has a wide range of application fields. For example, polymer material drying, resin curing, pharmaceutical manufacturing, baking paint, printing baking, disinfection, and heating in scientific research institutions. In some experimental processes, drying ovens are also used to dry experimental instruments such as beakers and test tubes.

[0004] After the traditional dryer finishes drying, the tray needs to be pulled out to take out the experimental instruments. However, the temperature of the just-dried experimental instruments and the tray is generally relatively high. If the staff directly touches them by hand, there may be a risk of scalding. Therefore, an oven device for experimental instruments is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, after the traditional dryer finishes drying, the tray needs to be pulled out to take out the experimental instruments. However, the temperature of the just-dried experimental instruments and the tray is generally relatively high. If the staff directly touches them by hand, there may be a risk of scalding. The utility model proposes an oven device for experimental instruments.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: An oven device for experimental instruments of the present utility model includes a drying box, on the surface of which a protective door is hinged. A group of guide rails are fixedly connected to the inner wall of the drying box. There are two guide rails, and a pair of the guide rails are symmetrically distributed around the central axis of the drying box. A tray is slidably connected between the guide rails. The surface of the tray is provided with mesh holes. A support plate is fixedly connected to the surface of the tray, and a number of mounting holes are provided on the surface of the support plate. A connecting block is fixedly connected to the bottom surface of the tray. A through groove is provided on the surface of the guide rail, and the connecting block passes through the through groove and is slidably connected. A elastic piece is fixedly connected to the inner wall of the drying box, and the other end of the elastic piece is fixedly connected to the surface of the connecting block. When it is necessary to dry the experimental instruments, the protective door is opened. At this time, the connecting block in the guide rail moves towards the opening of the drying box under the drive of the elastic piece, pushing out the tray. At the same time, the tray drives the support plate to move. Then, the instruments to be dried are reversely inverted into the mounting holes, and the tray is pushed inwards. Then, the drying box is started, so that the heating wire in the drying box cooperates with the blower to dry the experimental instruments. The elastic piece cooperates with the tray to automatically push out the tray, avoiding the staff from taking and placing equipment, and avoiding the high temperature of the just-dried tray from scalding the staff. The mesh holes on the surface of the tray can improve the air circulation effect, thereby improving the drying effect.

[0007] Preferably, a top block is slidably connected to the surface of the connecting block through a spring. A notch is provided on the surface of the through groove at a position corresponding to the top block. A rubber sheet is bonded to the surface of the top block. After the tray pops outwards, the top block on the surface of the connecting block will automatically snap into the notch under the drive of the spring to limit the tray, avoiding the tray from shaking when the staff places experimental equipment, which affects the operation of the staff. At the same time, the rubber sheet on the surface of the top block can play a role in decelerating when the connecting block slides.

[0008] Preferably, a slide rail is fixedly connected to the inner wall of the drying box, and a support rod is slidably connected in the slide rail. The other end of the support rod is fixedly connected to the surface of the elastic piece. Through the support rod, when the elastic piece slides back and forth, it can play a supporting role, avoiding the elastic piece from deforming to both sides and reducing the elastic potential energy generated by the elastic piece.

[0009] Preferably, a bottom block is fixedly connected to the surface of the elastic piece. A top shaft is slidably connected to the surface of the bottom block through a spring. An impact block is fixedly connected to the surface of the top shaft. When the elastic piece is compressed, it will generate displacement and drive the bottom block to move at the same time. The bottom block drives the top shaft to move. When the tray moves to the position of the top shaft, the tray will squeeze the arc angle on the surface of the top shaft, causing the top shaft to retract into the bottom block. When the top shaft moves to the position of the mesh hole, the spring drives the top shaft to reset and drives the impact block to impact the tray at the same time, so that the moisture on the surface of the tray falls off, thereby improving the drying efficiency.

[0010] Preferably, two sliding rails are provided, and a pair of the sliding rails are symmetrically distributed about the central axis of the drying box. The two sliding rails can improve the stability of the tray during sliding and prevent the situation of jamming due to unbalanced sliding on both sides.

[0011] Preferably, a cavity is formed in the support plate. A sliding rod is slidably connected to the cavity through a spring. The other end of the sliding rod penetrates through the cavity and is fixedly connected to a clamping plate at the end. When the experimental instrument is clamped into the installation groove, the clamping plate will be squeezed, causing the clamping plate to drive the sliding rod to retract into the cavity, and at the same time, the spring will be stretched. The experimental instrument can be positioned through the clamping plate to prevent shaking, thereby avoiding the inertial breakage of the equipment when it pops out.

[0012] Preferably, the clamping plate is arc-shaped, and a plurality of convex blocks are fixedly connected to the surface of the clamping plate, and the convex blocks are made of rubber. The convex blocks can reduce the contact area between the clamping plate and the outer wall of the experimental equipment, thereby improving the drying effect.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model can automatically push out the tray through the elastic sheet and the tray, avoiding the staff from taking and placing the equipment, and avoiding the high temperature of the just-dried tray from scalding the staff. The mesh holes on the surface of the tray can improve the air circulation effect, thereby improving the drying effect.

[0015] 2. When the elastic sheet is compressed, the displacement generated will drive the bottom block to move, and the bottom block drives the top shaft to move. When the tray moves to the position of the top shaft, the tray will squeeze the arc angle on the surface of the top shaft, causing the top shaft to retract into the bottom block. When the top shaft moves to the position of the mesh hole, the spring drives the top shaft to reset, and at the same time drives the impact block to impact the tray, causing the moisture on the surface of the tray to fall off, thereby improving the drying efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] Example 1

[0026] Please refer to Figures 1-5As shown in the figure, an oven device for experimental instruments includes a drying box 1. A protective door is hinged to the surface of the drying box 1. A group of guide rails 2 are fixedly connected to the inner wall of the drying box 1. There are two guide rails 2, and a pair of the guide rails 2 are symmetrically distributed around the central axis of the drying box 1. A tray 6 is slidably connected between the guide rails 2. The surface of the tray 6 is provided with mesh holes. A support plate 5 is fixedly connected to the surface of the tray 6. A number of mounting holes 4 are provided on the surface of the support plate 5. A connecting block 8 is fixedly connected to the bottom surface of the tray 6. A through groove 3 is provided on the surface of the guide rail 2. The connecting block 8 passes through the through groove 3 and is in sliding connection. An elastic piece 11 is fixedly connected to the inner wall of the drying box 1. The other end of the elastic piece 11 is fixedly connected to the surface of the connecting block 8. When working, when it is necessary to dry the experimental instruments, the protective door is opened. At this time, the connecting block 8 in the guide rail 2 moves towards the opening of the drying box 1 under the drive of the elastic piece 11, pushing out the tray 6. At the same time, the tray 6 drives the support plate 5 to move. Then the experimental instruments to be dried are reversely inverted into the mounting holes 4, and the tray 6 is pushed inwards. Then the drying box 1 is started, so that the heating wire in the drying box 1 cooperates with the blower to dry the experimental instruments. The elastic piece 11 cooperates with the tray 6 to automatically push out the tray 6, avoiding the staff from taking and placing the equipment, and avoiding the tray 6 with too high temperature after drying from scalding the staff. The mesh holes on the surface of the tray 6 can improve the air circulation effect, and thus improve the drying effect.

[0027] A top block 16 is slidably connected to the surface of the connecting block 8 through a spring. A notch 18 is provided on the surface of the through groove 3 at the position corresponding to the top block 16. A rubber sheet 17 is bonded to the surface of the top block 16. When working, after the tray 6 pops outwards, the top block 16 on the surface of the connecting block 8 will automatically snap into the notch 18 under the drive of the spring to limit the tray 6, avoiding the tray 6 from shaking when the staff places the experimental equipment, which affects the operation of the staff. At the same time, the rubber sheet 17 on the surface of the top block 16 can play a role in decelerating when the connecting block 8 slides.

[0028] A slide rail 9 is fixedly connected to the inner wall of the drying box 1. A support rod 10 is slidably connected in the slide rail 9. The other end of the support rod 10 is fixedly connected to the surface of the elastic piece 11. When working, through the support rod 10, when the elastic piece 11 slides back and forth, it can play a supporting role, avoiding the elastic piece 11 from deforming to both sides and reducing the elastic potential energy generated by the elastic piece 11.

[0029] A bottom block 14 is fixedly connected to the surface of the elastic piece 11. A top shaft 12 is slidably connected to the surface of the bottom block 14 through a spring. An impact block 13 is fixedly connected to the surface of the top shaft 12. During operation, when the elastic piece 11 is compressed, displacement will occur, driving the bottom block 14 to move at the same time. The bottom block 14 drives the top shaft 12 to move. When the tray 6 moves to the position of the top shaft 12, the tray 6 will squeeze the arc angle on the surface of the top shaft 12, causing the top shaft 12 to retract into the bottom block 14. When the top shaft 12 moves to the position of the mesh hole, the spring drives the top shaft 12 to reset, and at the same time drives the impact block 13 to impact the tray 6, causing the moisture on the surface of the tray 6 to fall off, thereby improving the drying efficiency.

[0030] Two slide rails 9 are provided. A pair of the slide rails 9 are symmetrically distributed about the central axis of the drying box 1. During operation, the two slide rails 9 can improve the stability of the tray 6 during sliding, and avoid the situation of jamming caused by unbalanced sliding on both sides.

[0031] Embodiment 2

[0032] Please refer to Figure 6 As shown, compared with Embodiment 1, as another implementation manner of the present invention, a cavity 22 is formed in the support plate 5. A sliding rod 21 is slidably connected to the cavity 22 through a spring. The other end of the sliding rod 21 penetrates through the cavity 22 and a clamping plate 20 is fixedly connected to the end. During operation, when the experimental instrument is clamped into the installation groove, the clamping plate 20 will be squeezed, causing the clamping plate 20 to drive the sliding rod 21 to retract into the cavity 22, and at the same time, the spring will be stretched. The experimental instrument can be positioned through the clamping plate 20 to prevent shaking, thereby avoiding the inertia generated during ejection from breaking the equipment.

[0033] The clamping plate 20 is arc-shaped. A plurality of convex blocks 19 are fixedly connected to the surface of the clamping plate 20, and the convex blocks 19 are made of rubber material. During operation, the contact area between the clamping plate 20 and the outer wall of the experimental equipment can be reduced through the convex blocks 19, thereby improving the drying effect.

[0034] Working principle: When the experimental instrument needs to be dried, the protective door is opened. At this time, the connecting block 8 in the guide rail 2 moves towards the opening of the drying box 1 driven by the elastic piece 11, pushing out the tray 6. At the same time, the tray 6 drives the support plate 5 to move. Then, the experimental instrument to be dried is reversely inverted into the installation hole 4, the tray 6 is pushed inwards, and then the drying box 1 is started, so that the heating wire in the drying box 1 cooperates with the blower to dry the experimental instrument. The elastic piece 11 cooperates with the tray 6 to automatically push out the tray 6, avoiding the staff from taking and placing the equipment, avoiding the high temperature of the just-dried tray 6 from scalding the staff. The mesh holes on the surface of the tray 6 can improve the air circulation effect, thereby improving the drying effect;

[0035] After the tray 6 pops outwards, the top block 16 on the surface of the connecting block 8 will automatically snap into the notch 18 under the drive of the spring to limit the tray 6, preventing the tray 6 from shaking when the staff places experimental equipment, which affects the operation of the staff. At the same time, the rubber sheet 17 on the surface of the top block 16 can slow down the speed when the connecting block 8 slides. Through the support rod 10, when the elastic sheet 11 slides back and forth, it can play a supporting role to prevent the elastic sheet 11 from deforming to both sides and reducing the elastic potential energy generated by the elastic sheet 11;

[0036] When the elastic sheet 11 is compressed, it will generate displacement and drive the bottom block 14 to move at the same time. The bottom block 14 drives the top shaft 12 to move. After the tray 6 moves to the position of the top shaft 12, the tray 6 will squeeze the arc angle on the surface of the top shaft 12, causing the top shaft 12 to retract into the bottom block 14. When the top shaft 12 moves to the mesh hole position, the spring drives the top shaft 12 to reset and drives the impact block 13 to impact the tray 6 at the same time, causing the moisture on the surface of the tray 6 to fall off, thereby improving the drying efficiency. When the experimental instrument is clamped into the installation groove, it will squeeze the clamping plate 20, causing the clamping plate 20 to drive the sliding rod 21 to retract into the cavity 22, and at the same time stretch the spring. The experimental instrument can be positioned through the clamping plate 20 to prevent shaking, thereby avoiding the inertial breakage of the equipment during ejection.
