Abstract
Description
Technical Field
[0001] This utility model relates to the field of oven tray technology, specifically a stackable sample tray. Background Technology
[0002] Industrial electric ovens use an electric heating system to heat workpieces, typically from room temperature to several hundred degrees Celsius. They are commonly used for heat treatment, surface treatment, drying and dehumidification, or aging reliability testing of metal workpieces. Workpieces are usually placed on a tray, or sample tray. The sample tray supports the workpieces during processing inside the industrial electric oven and is often used for heat conduction. Prior art CN202220227542.2 describes a steamer, a steam oven, and a tray for an oven.
[0003] Currently, sample trays are placed on wire racks inside an electric oven for heating. To avoid workpiece collisions and uneven heat radiation, workpieces cannot be directly stacked. This results in most wire racks only being able to hold one set of sample trays per layer, failing to effectively utilize the oven's internal space. Secondly, placing metal workpieces on bottom-sealed sample trays easily leads to temperature differences between the bottom and surface, resulting in inconsistent heat treatment outcomes for the metal workpieces.
[0004] To address these issues, we provide a stackable sample tray. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a stackable sample tray to solve the technical problem that the heat radiation utilization rate is low because metal workpieces in the existing electric oven can only be placed in a single row in a single layer, while the other spaces of the mesh rack cannot be effectively utilized.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A stackable sample tray, comprising:
[0008] The sample disc body includes an upper ring and a lower recess. The upper ring is integrally set at the edge of the lower recess. A recessed area is set in the lower recess, and a grid plate is installed in the recessed area. The workpiece is placed on the grid plate.
[0009] Fixed support plates are installed at the bottom of the upper ring of the sample disc and multiple sets are arranged circumferentially.
[0010] A rotating body has a rotating shaft mounted on a fixed support plate, and the rotating shaft is connected to the rotating body; the rotating body is adapted to rotate relative to the fixed support plate; the bottom of the rotating body is in the shape of an inverted cone; a bearing cylinder is installed on the upper side of the upper ring, and the bearing cylinder is adapted to the bottom of the rotating body;
[0011] A guide plate, which is arc-shaped and mounted on the rotating body, is suitable for limiting the rotation angle of the rotating body.
[0012] The height of the workpiece placed on this layer of grid plate should not be greater than the height from the bottom of the sample plate of the previous layer to the grid plate. This way, the workpiece can be placed on the sample plates that are set up layer by layer, avoiding the situation where the workpiece cannot be placed or the rotating body of the previous layer cannot be inserted into the bearing cylinder of this layer.
[0013] In a further technical solution, four sets of fixed support plates are provided, and each set of fixed support plates has two plates, which are located at the four corners of the sample plate.
[0014] A rotating shaft is installed between two fixed support plates in the same group. The rotating shaft is fixedly connected to the rotating body and passes through the rotating body.
[0015] In a further technical solution, the rotating body includes an upper cylindrical part and a conical part, the conical part being integrally formed with the upper cylindrical part; and the conical part tapers towards the end away from the upper cylindrical part;
[0016] A strip-shaped groove is provided on the conical part, and the strip-shaped groove is arranged circumferentially.
[0017] In a further technical solution, the height difference between the grid plate and the bottom of the recessed area is between 1 / 2 and 2 / 3 of the height of the recessed area.
[0018] In a further technical solution, the guide plate is an arc-shaped plate; a position shaft is installed on the rotating shaft, and the two ends of the position shaft are fixed in the corresponding fixed support plate;
[0019] An arc-shaped hole is provided on the position axis, and the guide plate is adapted to pass through the arc-shaped hole; and two sets of groove openings are provided on the guide plate, the two sets of groove openings being points A and B respectively; a limiting member is installed in the fixed support plate, the limiting member being adapted to abut against the groove opening to restrict the movement of the guide plate.
[0020] In a further technical solution, the limiting component includes a limiting housing, which is detachably connected to a corresponding fixed support plate. A position cavity is provided inside the limiting housing, and a position spring is installed inside the position cavity. One end of the position spring is fixedly connected to the inner wall of the limiting housing, and a fixing plate is installed at the other end. The fixing plate is I-shaped and extends to the outside of the limiting housing and is fitted with a limiting abutment. The limiting abutment is adapted to the groove opening.
[0021] In a further technical solution, when the rotating body is in a vertical position, the groove opening B abuts against the limiting member, and the bottom height of the rotating body is lower than the bottom height of the recessed part; when the rotating body is in a horizontal position, the groove opening A abuts against the limiting member, and the bottom height of the rotating body is higher than the bottom height of the recessed part.
[0022] In a further technical solution, the vertical cross-section of the guide plate is I-shaped; both sides of the guide plate are provided with grooves, and two grooves are symmetrically arranged in each group; both sides of the guide plate are equipped with limit housings.
[0023] Compared with existing technologies, it has the following advantages:
[0024] This invention separates the workpiece from the baking tray using a grid plate, and the bottom cavity allows hot air to directly contact the workpiece from below. Combined with the heat radiation from the top / side of the oven, it forms all-round heating from top to bottom and left to right, which is beneficial for the comprehensive heating of the workpiece.
[0025] This invention features a rotatable body at the bottom of the sample tray, which acts as a rotatable support leg and can be interlocked during stacking. Its inverted conical shape facilitates processing and interlocking. An arc-shaped guide plate is provided on the rotatable body to guide rotation and limit the rotation angle.
[0026] The guide plate has grooves A and B. The limiting member abuts against the guide plate to achieve positioning on both sides. The limiting member abuts against the fixed plate through a position spring, forcing the limiting abutment to abut against the groove to determine the rotation position of the guide plate within the position axis.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Example 1
[0042] like Figure 1-8 The image shows one embodiment of this utility model: a stackable sample tray, comprising:
[0043] The sample tray 1 includes an upper ring 2 and a lower recess 3. The upper ring 2 is integrally set at the edge of the lower recess 3. A recessed area is provided in the lower recess 3, and a grid plate 4 is installed in the recessed area. The workpiece is placed on the grid plate 4. The sample tray is rectangular or square and its main function is to support the workpiece, especially the metal workpiece, in the industrial oven or on the external shelf. Here, the shelf refers to the function of stacking and supporting the workpiece.
[0044] Fixed support plate 5 is installed at the bottom of the upper ring 2 of the sample disc body 1 and multiple sets are arranged in a circumferential distribution.
[0045] A rotating body 6 has a rotating shaft 7 mounted on a fixed support plate 5, and the rotating shaft 7 is connected to the rotating body 6. The rotating body 6 is adapted to rotate relative to the fixed support plate 5. The bottom of the rotating body 6 is in the shape of an inverted cone. The rotating body acts as a rotatable support leg, allowing for interlocking when stacked. The inverted cone shape facilitates processing and interlocking. A bearing cylinder 11 is mounted on the upper side of the upper ring 2, and the bearing cylinder 11 is adapted to the bottom of the rotating body 6.
[0046] The guide plate 8 is arc-shaped and mounted on the rotating body 6, and is suitable for limiting the rotation angle of the rotating body 6.
[0047] Further as Figure 2 As shown, four sets of fixed support plates 5 are provided, and each set of fixed support plates 5 has two plates, which are located at the four corners of the sample plate body 1; a rotating shaft 7 is installed between the two fixed support plates 5 in the same set, the rotating shaft 7 is fixedly connected to the rotating body 6, and the rotating shaft 7 passes through the rotating body 6.
[0048] like Figure 3 and 8 As shown, the rotating body 6 includes an upper cylindrical portion 61 and a conical portion 62, which is integrally formed with the upper cylindrical portion 61. The conical portion 62 tapers towards the end away from the upper cylindrical portion 61. A strip-shaped groove 63 is provided on the conical portion 62, and the strip-shaped groove 63 is arranged circumferentially. The strip-shaped groove serves to prevent the rotating body from being completely closed and unable to be pulled out when it is inserted into the bearing cylinder 11, thus achieving the effect of easy insertion and removal.
[0049] Combination Figure 4 and Figure 6 As shown, the height difference between the grid plate 4 and the bottom of the recessed area is between 1 / 2 and 2 / 3 of the height of the recessed area. The grid plate can be made of high-temperature resistant stainless steel (such as 310S) or a nickel-based alloy, with an anti-stick coating sprayed on the surface. The grid plate is shaped as follows: Figure 2 The diagram shows the alternating arrangement of horizontal and vertical bars.
[0050] The design of placing metal workpieces on a baking tray in an electric oven with a grid plate and a bottom cavity significantly improves the efficiency and quality of metal processing by optimizing heat conduction, airflow circulation, and process adaptability. The grid plate separates the workpiece from the baking tray, and the bottom cavity allows hot air to directly contact the workpiece from below. Combined with heat radiation from the top and sides of the oven, this creates all-around heating, avoiding the problem of insufficient heating of the bottom of the workpiece due to contact with the baking tray in traditional flat-laying methods.
[0051] like Figure 8As shown, the guide plate 8 is an arc-shaped plate; a position shaft 9 is installed on the rotating shaft 7, and both ends of the position shaft 9 are fixed in the corresponding fixed support plate 5; an arc-shaped hole 91 is opened on the position shaft 9, and the guide plate 8 is adapted to pass through the arc-shaped hole 91; and two sets of grooves 81 are opened on the guide plate 8, the two sets of grooves 81 being points A and B respectively; a limiting member 10 is installed in the fixed support plate 5, and the limiting member 10 is adapted to abut against the grooves 81 to restrict the movement of the guide plate 8. The specific machining of points A and B is designed according to the actual design of the position shaft and the hole position on the rotating body. When the positions of points A and B are determined, the rotation of the guide plate is realized based on the connection hole position between the rotating body and the rotating shaft as the center. For fixing the guide plate at points A and B, it is possible to consider inserting a pin through the fixed support plate to connect the fixed support plate and the guide plate. A closing plate is provided at the end of the guide plate away from the rotating body. The size of the closing plate is larger than the diameter of the arc-shaped hole, thereby preventing the guide plate from detaching from the arc-shaped hole. Furthermore, when the rotating body is positioned outside the position axis and abuts against the closed plate, it stands vertically downwards.
[0052] Example 2
[0053] like Figure 9-11 As shown, another embodiment of this utility model is presented. Based on embodiment 1, in order to achieve the horizontal and vertical distribution of the corresponding rotating bodies when the groove openings A and B are connected to the limiting member, the limiting member 10 is designed to include a limiting housing 101. The limiting housing 101 is detachably connected to the corresponding fixed support plate 5, and a position cavity is provided inside the limiting housing 101. A position spring 102 is installed in the position cavity. One end of the position spring 102 is fixedly connected to the inner wall of the limiting housing 101, and a fixing plate 103 is installed at the other end. The fixing plate 103 is I-shaped and extends to the outside of the limiting housing 101 and is fitted with a limiting abutment 104. The limiting abutment 104 is adapted to the groove opening 81. The position spring can be made of 304 stainless steel, which is heat-resistant at high temperatures and can maintain the function of the position spring for a longer period of time.
[0054] When the rotating body 6 is in a vertical position, the groove opening 81B abuts against the limiting member 10, and the bottom height of the rotating body 6 is lower than the bottom height of the lower recess 3; when the rotating body 6 is in a horizontal position, the groove opening 81A abuts against the limiting member 10, and the bottom height of the rotating body 6 is higher than the bottom height of the lower recess 3.
[0055] Combination Figure 11 As shown, the vertical cross-section of the guide plate 8 is I-shaped; both sides of the guide plate 8 are provided with grooves 81, and two grooves 81 are symmetrically arranged in each group; limit housings 101 are installed on both sides of the guide plate 8. Figure 11In the middle, the vertical cross-section of the guide plate is I-shaped, and the bottom is a longitudinally inward-facing closed plate. The grooves on both sides of the I-shape abut against the limiting abutments on the fixed plate, thereby preventing the guide plate from rotating and controlling the rotation position of the rotating body through the guide plate.
[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
