Laboratory oven flaky sample holder

Abstract

The utility model relates to the technical field of sample clamping, and provides a lab oven flaky sample holder which comprises a square plate and a plurality of square blocks fixedly mounted at four corners of the top of the square plate respectively. According to the utility model, the controller is used for controlling the air cylinder to contract, so that the air cylinder drives the clamping plate to move upwards and the movable rod to slide upwards, thereby driving the sheet-shaped sample to move upwards, enabling the sheet-shaped sample to be in contact with the bottom of the supporting plate and applying a pushing force to the sheet-shaped sample, enabling the supporting plate to drive the rotating rod to rotate upwards and synchronously enabling the torsion spring to twist; when the sheet-shaped samples move to a certain height, the thrust applied to the supporting plate disappears, the supporting plate and the rotating rod can rotate downwards and reset under the reset acting force of the torsion spring, and the operation is repeated, so that a plurality of sheet-shaped samples can be temporarily placed on the supporting plate, and the sheet-shaped samples do not need to be frequently placed at specified positions; therefore, the clamping efficiency of the sheet-shaped sample is improved.

Description

Technical Field

[0001] This utility model relates to the field of sample clamping technology, and in particular to a sheet sample holder for a laboratory oven. Background Technology

[0002] Laboratory ovens (also known as drying ovens or baking ovens) are among the most commonly used pieces of equipment in laboratories, primarily used for drying, heating, sterilizing, and heat treating samples. They have wide applications in many fields, including chemistry, biology, medicine, and materials science.

[0003] In the existing technology, laboratory ovens are used to dry samples of different types and shapes. A clamp is required to hold the samples. However, the sheet sample clamp is used in a different state when the sheet sample is placed in the oven. This means that the clamp can only hold a single sheet sample at a time and then place the held sheet sample in a designated position. This process is repeated, which results in low efficiency in holding sheet samples. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where laboratory ovens are used to dry samples of different types and shapes, requiring the use of a clamp to hold the samples. In particular, the sheet sample clamp is used because the sheet samples are placed in different states in the oven, so the clamp can only hold one sheet sample at a time and then place the clamped sheet sample in a designated position. This process is repeated, resulting in low efficiency in holding sheet samples.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a laboratory oven sheet sample holder, comprising: a square plate, and further comprising:

[0006] Multiple blocks are fixedly installed at the four corners of the top of the square plate. The multiple blocks are divided into two groups. Guide rods are fixedly installed on the opposite side of the two groups of blocks. Two U-shaped sliders are symmetrically and movably sleeved on the outer surface of the two guide rods. A cylinder is fixedly embedded at the center of the bottom of the two U-shaped sliders. A clamping plate is fixedly installed at one end of the two cylinders.

[0007] Multiple vertical bars are symmetrically fixedly installed in pairs at the bottom of the square plate. The multiple vertical bars are divided into two groups. A rotating rod is movably embedded on the opposite side of the two groups of vertical bars near the bottom. A support plate is fixedly sleeved on the outer surface of each of the two rotating rods. A limiting block is fixedly sleeved on both ends of each of the two rotating rods. A torsion spring is movably sleeved on both ends of each of the multiple vertical bars near the bottom. A limiting strip is fixedly installed on the side of the multiple vertical bars near the bottom.

[0008] Preferably, one end of each of the torsion springs is fixedly installed on the other side of the multiple vertical bars near the bottom, and the other end of each of the torsion springs is fixedly installed on one side of the multiple limiting blocks. Under the restoring force of the torsion springs, the limiting blocks can always be in contact with the limiting bars, and the limiting bars limit the limiting blocks, thereby keeping the support plate in a horizontal state.

[0009] Preferably, a U-shaped plate is fixedly installed on the top of the square plate, and a rotating shaft is movably embedded in the center of the top of the U-shaped plate. A connecting strip is fixedly sleeved on one end of the rotating shaft. A motor is fixedly installed on the top of the U-shaped plate, and the output end of the motor is fixedly installed on the other end of the rotating shaft. The motor is started by controlling the controller, so that its output shaft can drive the rotating shaft and the connecting strip to rotate.

[0010] Preferably, the top of the square plate is provided with two connecting strips II. Two round rods are symmetrically fixedly installed on the top of each of the two connecting strips II. One end of each of the two round rods is symmetrically and movably embedded in the bottom of the connecting strip I, and the other two round rods are respectively movably embedded in the top of the inner wall of the two U-shaped sliders. With the above arrangement, when the connecting strip I rotates, it will apply a pulling force to the connecting strip II, which can drive the U-shaped slider to slide in the middle along the outer surface of the guide rod.

[0011] Preferably, each of the two U-shaped sliders has two movable rods symmetrically and movably embedded at its bottom. The multiple movable rods are symmetrically and fixedly installed on the top of the two clamping plates in pairs. The movable rods provide support for the clamping plates and improve the stability of the clamping plates in holding sheet-like samples.

[0012] Preferably, a telescopic rod is fixedly installed at the center of the bottom of the square plate, a compression spring is fixedly installed at one end of the telescopic rod, and a connecting arm is fixedly installed on one side of the square plate. With the above arrangement, the telescopic rod can be extended or retracted, so that the compression spring can move up and down to a certain extent.

[0013] Preferably, a pressure plate is movably fitted onto the outer surface of the telescopic rod. One end of the pressure plate is fixedly installed at the bottom of the square plate, and the other end of the pressure plate is fixedly installed at the top of the compression spring. Under the reset force of the pressure plate, the compression spring can have a downward tendency to move.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model controls the motor to start via a controller, causing its output shaft to drive the rotating shaft and connecting bar one to rotate counterclockwise. With the cooperation of the round rod, a pulling force is applied to the connecting bar two, causing the connecting bar one to rotate around the connected round rod at an appropriate angle. Simultaneously, this causes the U-shaped slider to slide inwards along the outer surface of the guide rod, simultaneously moving the cylinder, clamping plate, and movable rod towards the center to clamp and fix the sheet-like sample. At this time, the controller controls the cylinder to retract, causing it to move the clamping plate upwards, and the movable rod to slide upwards, thereby moving the sheet-like sample upwards, so that the sheet-like sample is aligned with the support plate. The bottom of the plate contacts the support plate and applies a thrust, causing the support plate to rotate upwards along with the rotating rod. Simultaneously, the torsion spring twists. When the sheet sample moves to a certain height, the thrust on the support plate disappears. Under the restoring force of the torsion spring, the support plate and rotating rod can rotate downwards to reset. The angle of rotation of the limiting block can be limited by the limiting strip, thus keeping the support plate horizontal. This process is repeated, allowing multiple sheet samples to be temporarily placed on the support plate without frequently moving them to the designated position, thereby improving the efficiency of sheet sample clamping.

[0016] 2. In this invention, when the sheet-like sample moves upward, it comes into contact with the compression spring and applies an upward thrust to the spring, causing it to move upward. Simultaneously, the telescopic rod retracts, compressing the pressure plate. When the thrust on the spring disappears, the spring moves downward under the resetting force of the pressure plate, simultaneously extending the telescopic rod. This causes the spring to press against the sheet-like sample, thus securing it against the support plate and preventing it from falling. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

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.

[0025] Example 1, such as Figure 1-4 As shown, this utility model provides a laboratory oven sheet sample holder, including: a square plate 1, and also including: multiple blocks 102, which are fixedly installed at the four corners of the top of the square plate 1. The multiple blocks 102 are divided into two groups. Guide rods 103 are fixedly installed on the opposite side of the two groups of blocks 102. Two U-shaped sliders 104 are symmetrically and movably sleeved on the outer surface of the two guide rods 103. A cylinder 4 is fixedly embedded at the center of the bottom of the two U-shaped sliders 104. A clamping plate 401 is fixedly installed at one end of the two cylinders 4.

[0026] Multiple vertical bars 2 are symmetrically fixedly installed in pairs at the bottom of the square plate 1. The multiple vertical bars 2 are divided into two groups. A rotating rod 201 is movably embedded on the opposite side of the two groups of vertical bars 2 near the bottom. A support plate 202 is fixedly sleeved on the outer surface of the two rotating rods 201. A limiting block 203 is fixedly sleeved on both ends of the two rotating rods 201. A torsion spring 204 is movably sleeved on both ends of the two rotating rods 201. A limiting strip 205 is fixedly installed on the side of the multiple vertical bars 2 near the bottom.

[0027] Furthermore, such as Figure 1-4 As shown, one end of each torsion spring 204 is fixedly installed on the other side of each vertical bar 2 near the bottom, and the other end of each torsion spring 204 is fixedly installed on one side of each limiting block 203.

[0028] Furthermore, such as Figure 1-4As shown, a U-shaped plate 105 is fixedly installed on the top of the square plate 1. A rotating shaft 107 is movably embedded in the center of the top of the U-shaped plate 105. A connecting strip 108 is fixedly sleeved on one end of the rotating shaft 107. A motor 106 is fixedly installed on the top of the U-shaped plate 105. The output end of the motor 106 is fixedly installed on the other end of the rotating shaft 107.

[0029] Furthermore, such as Figure 1-4 As shown, the top of the square plate 1 is provided with two connecting strips 110. Two round rods 109 are symmetrically fixedly installed on the top of each of the two connecting strips 110. One end of each of the two round rods 109 is symmetrically and movably embedded in the bottom of the connecting strip 108, and the other two round rods 109 are respectively movably embedded in the top of the inner wall of the two U-shaped sliders 104.

[0030] Furthermore, such as Figure 1-4 As shown, two movable rods 402 are symmetrically and movably embedded at the bottom of each of the two U-shaped sliders 104, and multiple movable rods 402 are symmetrically and fixedly installed on the top of the two clamping plates 401 in pairs.

[0031] Furthermore, such as Figure 1-4 As shown, a telescopic rod 3 is fixedly installed at the center of the bottom of the square plate 1, a compression spring 301 is fixedly installed at one end of the telescopic rod 3, and a connecting arm 101 is fixedly installed on one side of the square plate 1.

[0032] Furthermore, such as Figure 1-4 As shown, a pressure plate 302 is movably sleeved on the outer surface of the telescopic rod 3. One end of the pressure plate 302 is fixedly installed at the bottom of the square plate 1, and the other end of the pressure plate 302 is fixedly installed at the top of the compression spring 301.

[0033] Working Principle: During use, the controller starts the motor 106, causing its output shaft to drive the rotating shaft 107 and connecting bar 108 to rotate counterclockwise. With the cooperation of the round rod 109, a pulling force is applied to the connecting bar 110, causing the connecting bar 108 to rotate around the connected round rod 109 at an appropriate angle. Simultaneously, this drives the U-shaped slider 104 to slide along the outer surface of the guide rod 103 towards the center, simultaneously moving the cylinder 4, clamping plate 401, and movable rod 402 towards the center to clamp and fix the sheet sample. At this time, the controller controls the cylinder 4 to retract, causing it to move the clamping plate 401 upwards, and the movable rod 402 to slide upwards, thereby moving the sheet sample upwards until it contacts the bottom of the support plate 202, applying a pushing force to it. This causes the support plate 202 to drive the rotating rod 201 to rotate upwards, simultaneously causing the torsion spring 204 to twist. When the sheet sample moves to a certain height, the pushing force on the support plate 202 disappears, and the torsion spring 204 returns to its original position. Under force, the support plate 202 and the rotating rod 201 can rotate downwards to reset. The limiting strip 205 can limit the rotation angle of the limiting block 203, thus keeping the support plate 202 in a horizontal state. This process is repeated, allowing multiple sheet samples to be temporarily placed on the support plate 202 without frequently placing them in the designated position, thereby improving the efficiency of sheet sample clamping. When the sheet sample moves upwards, it will contact the compression spring 301 and apply an upward thrust to the compression spring 301, causing it to move upwards. Simultaneously, the telescopic rod 3 retracts, compressing the pressure plate 302. When the thrust on the compression spring 301 disappears, the compression spring 301 can move downwards under the reset force of the pressure plate 302, simultaneously extending the telescopic rod 3, causing the compression spring 301 to squeeze the sheet sample. This can hold the sheet sample placed on the support plate 202 tightly, preventing it from falling off.

[0034] 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.
