[0038] Reference Figures 1-5This is the first embodiment of the present invention, which proposes a sample loading and unloading device for a laboratory heat treatment furnace, comprising: a movable body 1 having a support shaft 101; a first rod 2 rotatably disposed relative to the support shaft 101, and a second rod 3 movably disposed relative to the support shaft 101, with the first rod 2 and the second rod 3 respectively passing through both ends of the support shaft 101; both the first rod 2 and the second rod 3 having a hopper 4; the hopper 4 of the first rod 2 being located on one side of the hopper 4 of the second rod 3; and both being used to jointly support the sample; the first rod 2 being configured to determine the sample loading and unloading angle after rotation, and the second rod 3 being configured to cooperate with the position of the hopper 4 of the first rod 2 after movement.

[0039] In this embodiment, the working process of the sample placement and removal device is as follows:

[0040] When placing the sample, place the sample on the hopper section 4 of the first rod 2 and the second rod 3. First, adjust the position of the second rod 3 on the support shaft 101 according to the sample size, and move the second rod 3 so that the hopper sections 4 of the first rod 2 and the second rod 3 form a suitable distance and shape, and the two together support the sample. Then, stabilize the position and angle of the two sets of rods, and push the moving body 1 to move it close to the operating area of ​​the heat treatment furnace, ensuring that the hopper sections 4 of the first rod 2 and the second rod 3 are aligned with the sample to be treated or the furnace opening direction, until the sample reaches the predetermined heat treatment position in the furnace, and then withdraw the moving body 1.

[0041] When removing the sample, after the heat treatment is completed, first adjust the first rod 2 and the second rod 3 to the appropriate removal angle, then push the moving body 1 to make the first rod 2 and the second rod 3 reach the sample position, and then remove the sample from the furnace and transport it to the subsequent testing or storage area.

[0042] The second rod 3 can be movable in two ways: First, a manual screw-adjustable type, where a screw is installed at the end of the support shaft 101, and the screw is threadedly connected to the second rod 3. By rotating the screw, the second rod 3 moves on the support shaft 101 using the threaded transmission principle. A handle can be installed on the head of the screw. This method is simple and easy to operate and can accommodate samples of different widths. Second, a hydraulically driven type, where a small hydraulic cylinder is installed on the moving body 1, and the cylinder piston rod is connected to the second rod 3. By controlling the pressure and flow of the hydraulic system, the cylinder piston rod extends and retracts, driving the second rod 3 to move. This method provides greater driving force and is suitable for heavier samples or situations requiring rapid adjustment of the second rod 3's position. However, it is less adaptable to angle adjustments, requiring the bolt to be loosened before each adjustment.

[0043] Specifically, the mobile body 1 is a traditional vehicle frame structure with a metal frame. It is equipped with casters 10 or slide rails at the bottom for flexible movement on the laboratory floor. Both ends of the support shaft 101 are welded horizontally to the frame of the mobile body 1 at appropriate positions via triangular columns. The first rod 2 and the second rod 3 can be mounted on the support shaft 101 via bushings or bearings to enable smooth rotation or movement around the support shaft 101. The hopper 4 that supports the sample can be designed as an inwardly recessed arc or rectangular groove structure, made of high-temperature resistant metal materials, such as stainless steel or heat-resistant alloy steel. The surface can be specially treated to reduce friction and adhesion between the sample and the hopper 4.

[0044] Furthermore, the second rod 3 has a strip hole 301, and one end of the support shaft 101 passes through the strip hole 301.

[0045] Furthermore, it also includes: bearing 5 is sleeved on support shaft 101 and located in strip hole 301; ball 6 is disposed on outer wall of bearing 5, inner wall of strip hole 301 has groove 302, ball 6 is slidably disposed relative to groove 302 and ball 6 is located in groove 302.

[0046] In this embodiment, the second rod 3 moves through its slotted hole 301 and the bearing 5 sleeved on the support shaft 101, as well as the ball bearing 6 on the outer wall of the bearing 5. Specifically, one end of the support shaft 101 passes through the slotted hole 301 of the second rod 3. The bearing 5 is located inside the slotted hole 301, and the ball bearing 6 is arranged on the outer wall of the bearing 5. The inner wall of the slotted hole 301 is provided with a corresponding groove 302. When the position of the second rod 3 needs to be adjusted, the operator applies external force to the second rod 3, causing the ball bearing 6 to roll in the groove 302 on the inner wall of the slotted hole 301. This completely distinguishes the movement of the first rod 2 and the second rod 3. The first rod 2 only rotates, while the second rod 3 both rotates and slides. After the movement, the position of the hopper part 4 of the second rod 3 relative to the hopper part 4 of the first rod 2 can be flexibly changed according to the actual sample width, length, angle and other dimensional requirements after the angle position of the first rod 2 is determined. This forms an effective support and ultimately stabilizes the position and angle of the two sets of rods, ensuring the smooth progress of the entire subsequent heat treatment process.

[0047] By adopting the above-mentioned movement mode, the movement of the second rod 3 relative to the support shaft 101 becomes more flexible and smooth. At the same time, the way the ball 6 slides in the groove 302 transforms the original direct friction into rolling friction, which greatly reduces the friction between the second rod 3 and the support shaft 101 and the inner wall of its own strip hole 301 during the movement. It can also effectively reduce the wear between the components and extend the service life of the device. At the same time, it is easy to use the groove 302 to stabilize the position of the second rod 3, and it is not easy for the sample to be unstable due to positional displacement, thus ensuring the stability of the sample during the placement and removal process.

[0048] Furthermore, there are two slides 302 and two balls 6, which are symmetrically arranged, and the slides 302 and the balls 6 correspond one-to-one.

[0049] In this embodiment, two symmetrical balls 6 are provided and cooperate with corresponding grooves 302. Specifically, they can be configured on the top and bottom of the bearing 5, which can make the second rod 3 more evenly stressed when it moves on the support shaft 101. When the second rod 3 supports the sample and is adjusted in position or is subjected to external force during placement or removal, the two balls 6 evenly share the force, avoiding component deformation or positional displacement caused by excessive force at a single point.

[0050] Furthermore, the support shaft 101 has a plurality of first locking holes 102, which are arranged circumferentially around the support shaft 101 and are all located within the bearing 5. It also includes a first locking rod 7 slidably disposed on the bearing 5 and passing through the bearing 5. After sliding, the first locking rod 7 extends into or out of one of the first locking holes 102. The first locking rod 7 is configured to lock the relative rotation between the bearing 5 and the support shaft 101 after extending into one of the first locking holes 102.

[0051] In this embodiment, stabilizing the two sets of rods is mainly to ensure more stable sample placement and removal, rather than relying solely on uncertain external forces. Therefore, by using locking rods, the rotational relationship between the support shaft 101 and the second rod 3 can be locked. Under the premise that the angle between the first rod 2 and the second rod 3 is stabilized, the sliding is not affected. Furthermore, pushing and pulling the first rod 2 and the second rod 3 does not affect sample placement and removal. The second rod 3 can also slide relative to the support shaft 101 to accommodate samples of different lengths and dimensions, so that the experiment can continue.

[0052] Specifically, when it is necessary to lock the relative rotational relationship between the second rod 3 and the support shaft 101, the operator first moves the second rod 3 to the predetermined position so that the bearing 5 is in a suitable position. Then, the operator pushes the first locking rod 7 to slide along the sliding channel on the bearing 5 toward the support shaft 101. Since several first locking holes 102 are arranged circumferentially around the support shaft 101 and are all located inside the bearing 5, the first locking rod 7 will gradually approach the support shaft 101 during the sliding process and eventually extend into one of the first locking holes 102. At this time, the first locking rod 7 and the first locking hole 102 are tightly engaged, restricting the rotation of the bearing 5 relative to the support shaft 101, thereby locking the relative rotation of the second rod 3 and the support shaft 101.

[0053] Furthermore, it also includes: the first rod 2 is rotatably mounted on the support shaft 101 via the second bearing 8, and the outer wall of the second bearing 8 is fixedly connected to the first rod 2.

[0054] Furthermore, the support shaft 101 also has a plurality of second locking holes 103, which are arranged circumferentially around the support shaft 101 and are all located within the bearing 2. It also includes a second locking rod 9 slidably disposed on the bearing 2 and passing through the bearing 2. After sliding, the second locking rod 9 extends into or out of one of the second locking holes 103. The second locking rod 9 is configured to lock the relative rotation between the first rod 2 and the support shaft 101 after extending into one of the second locking holes 103.

[0055] In this embodiment, further consideration is given to using the same locking mechanism as the second rod 3 to stabilize the rotation angle of the first rod 2. This structure is simple, easy to operate, and ensures experimental consistency. Therefore, the operation process is as follows:

[0056] When it is necessary to lock the relative rotation between the first rod 2 and the support shaft 101, the operator first rotates the first rod 2 to the desired angle position. Then, the operator pushes the second locking rod 9 to slide along the preset sliding path on the bearing 8 toward the support shaft 101. Since multiple second locking holes 103 are arranged around the circumference of the support shaft 101 and are located inside the bearing 8, the second locking rod 9 will gradually approach the support shaft 101 during the sliding process and eventually insert into one of the second locking holes 103. At this time, the second locking rod 9 and the second locking hole 103 are tightly engaged, successfully restricting the rotation of the bearing 8 relative to the support shaft 101, thereby achieving the locking of the relative rotation between the first rod 2 and the support shaft 101.

[0057] Then, by adjusting the position of the second rod 3, the sample size is adapted. Finally, the first locking rod 7 is used to stabilize the angle position of the two sets of rods. After pushing the two sets of rods, the sample can be sent into the heat treatment furnace at a stable angle.

[0058] Furthermore, one end of the first rod 2 and one end of the second rod 3 each have a hopper section 4. The width of the hopper section 4 of the first rod 2 is less than the distance between the first rod 2 and the second rod 3, and the width of the hopper section 4 of the second rod 3 is equal to the distance between the first rod 2 and the second rod 3.

[0059] In this embodiment, the hopper section 4 at one end of the first rod 2 is designed to be relatively narrow, with a width smaller than the distance between the first rod 2 and the second rod 3. The width of the hopper section 4 at one end of the second rod 3 is equal to the distance between the first rod 2 and the second rod 3. This width difference creates a structural asymmetry, allowing for better adaptation to specimens of different shapes. For specimens with a narrow width but long length, such as long metal bars, the narrower hopper section 4 of the first rod 2 can effectively support them, preventing lateral rolling or slippage during transport. For specimens with a wider width, such as square or rectangular steel plates, the hopper section 4 of the second rod 3 provides sufficient support width, working in conjunction with the first rod 2 to ensure stable placement of the specimen and improving the device's compatibility with specimens of various shapes.

[0060] When taking out the sample, since the width of the first rod 2 hopper 4 is smaller, it is easier to avoid surrounding obstacles and take the lead in detaching from the sample when the angle or space is limited. Similarly, the gap between the two sets of hoppers 4 makes it easier to take out the sample through them.

[0061] Furthermore, the hopper section 4 has an opening 401, and the opening 401 of the first rod 2 faces the opening 401 of the second rod 3.

[0062] Furthermore, it also includes: omnidirectional wheels 10 are installed at the bottom of the moving body 1.

[0063] In this embodiment, the orientation of the opening 401 of the hopper 4 is designed so that when loading the sample, the operator can directly put the sample into the hopper 4 from the direction of the opening 401. After the sample is placed in the hopper 4, the opening 401 can limit the sample to a certain extent. The edge of the sample is in contact with or close to the edge of the opening 401, which restricts the lateral movement of the sample in the hopper 4 and reduces the positional displacement of the sample caused by shaking, vibration and other factors during the handling process.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
