Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying oven technology, specifically to a drying oven pull-out mechanism. Background Technology
[0002] There are many types of drying ovens, such as vacuum drying ovens and forced-air drying ovens. These drying ovens are used to evaporate the moisture in items, making them dry. A shelf is needed to store the materials in the drying oven, and a pull-out mechanism is required to pull the shelf and remove the items. However, existing pull-out mechanisms come in two specifications: one cannot pull the shelf out of the drying oven completely, but can only slide it a specified distance, which has certain limitations; the other cannot limit the sliding distance of the shelf. If the shelf slides too far, or if the operator operates it improperly, the shelf may lose balance and fall out of the drying oven, making the device inconvenient to operate. Utility Model Content
[0003] In view of this, the present invention provides a drying oven pull-out mechanism that can limit the sliding distance of the shelf to prevent it from slipping off, and can also choose to cancel the limit on the shelf, thereby removing the shelf as a whole from the drying oven, making it more convenient to operate and more applicable.
[0004] To solve the above-mentioned technical problems, this utility model provides a drying oven pull-out mechanism, including a drying oven and a shelf disposed inside the drying oven. Slide rails are provided on the two inner side walls of the drying oven, and slide bars are provided on the two side walls of the shelf. The slide bars are slidably disposed within the slide rails, and a positioning groove is formed on the rear side of the upper surface of the slide bars. A limiting mechanism is provided on the front side of the slide rails. The limiting mechanism includes a drive component and a positioning post. The drive component drives the positioning post to move up and down. By driving the positioning post to move up and down, the sliding distance of the shelf can be limited, preventing the shelf from slipping. Simultaneously, the limiting of the shelf can be canceled, allowing the shelf to be removed entirely from the drying oven. This makes operation more convenient and more versatile.
[0005] The drive assembly includes a limiting frame located on the front side of the upper surface of the slide rail. A movable plate is slidably mounted inside the limiting frame, and a positioning post is located at the bottom of the movable plate. A through groove adapted to the positioning post is opened on the lower surface of the limiting frame, and the through groove extends into the slide rail. The end of the positioning post passes through the through groove at the bottom of the limiting frame. A toggle component is provided on one side of the limiting frame surface. The toggle component is used to drive the movable plate to slide upward. If it is necessary to remove the shelf, the toggle component drives the movable plate and the positioning post to slide upward, causing the positioning post to disengage from the positioning groove. By removing the limiting of the slide bar, the slide bar can slide out of the slide rail, thereby removing the shelf, making the operation more convenient.
[0006] The actuating component includes a guide groove formed on one side of the surface of the limiting frame. A handle is slidably disposed in the guide groove. One end of the handle is connected to one side of the surface of the movable plate. Pulling the handle upward causes it to slide upward along the guide groove. The handle drives the movable plate to move upward synchronously, thereby causing the positioning post to disengage from the positioning groove.
[0007] The guide groove has an inverted L-shaped structure. The movable plate surface has a corresponding groove on one side of the guide groove. The end of the handle is slidably set in the groove on the side wall of the movable plate. When the handle is disengaged from the lateral position of the guide groove, the movable plate and the positioning column fall back to their original positions. This allows one person to easily and quickly remove the shelf.
[0008] A spring is installed at the upper end of the movable plate. The upper end of the spring is fixed to the upper side of the inner wall of the limiting frame, and the lower end of the spring is fixed to the upper surface of the movable plate. The spring's rebound force and the weight of the positioning post can push the positioning post downward, thereby making the positioning post tightly engaged in the positioning groove to improve stability.
[0009] The surface of the positioning post, especially the side facing the slide rail opening, is set as an inclined surface. When the worker continues to push the shelf, the positioning post will continue to move upward to disengage from the positioning groove. Then, by continuing to push the shelf, the slide bar can be completely slid into the slide rail to complete the installation of the shelf.
[0010] The handle surface is equipped with anti-slip raised strips, which enhance the handle's anti-slip properties and prevent it from slipping.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0012] 1. When using this utility model, the positioning column is moved up and down by the driving component, which can limit the sliding distance of the shelf and prevent the shelf from slipping. At the same time, the limit on the shelf can be canceled, so that the shelf can be taken out of the drying oven as a whole. It is more convenient to operate and has a wider range of applications.
[0013] 2. When using this utility model, by removing the limit on the slider, the slider can slide out from the slide rail, thereby removing the shelf, making the operation more convenient.
[0014] 3. When using this utility model, the handle is disengaged from the lateral position of the guide groove, thereby causing the movable plate and positioning column to fall and reset, allowing one person to complete the removal of the shelf, which is convenient and quick.
[0015] 4. When using this utility model, if the worker continues to push the shelf, the positioning post will continue to move upward to disengage from the positioning groove. Then, if the shelf is pushed further, the slide bar can be completely slid into the slide rail to complete the installation of the shelf. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0025] According to one embodiment of the present invention, such as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown: This embodiment provides a drying oven pull-out mechanism, including a drying oven 100 and a shelf 200 disposed inside the drying oven 100. The number of shelf 200 can be four or more. A slide rail 300 is provided on both inner side walls of the drying oven 100, corresponding to the positions on both sides of each shelf 200. A slide bar 201 is provided on both side walls of the shelf 200. The slide bar 201 is slidably disposed in the slide rail 300, and a positioning groove is provided on the rear side of the upper surface of the slide bar 201. A limit mechanism is provided on the front side of the slide rail 300. The limit mechanism includes a drive component and a positioning column. The drive component is used to drive the positioning column to move up and down.
[0026] When the operator needs to pull the shelf 200 out of the drying chamber 100 a certain distance without removing the shelf 200 entirely, the drying chamber 100 is opened, and then the desired shelf 200 is pulled. The sliding strips 201 on both sides of the shelf 200 slide within the sliding grooves 503. During the sliding process, when the positioning groove on the upper part of the sliding strip 201 corresponds to the position directly below the positioning post, and at this time most of the shelf 200 has been pulled out of the drying chamber 100, the operator can use the drive component to move the positioning post downwards, allowing the positioning post to insert into the positioning... The slide bar 201 is positioned within the groove, thus limiting and fixing it so that it cannot slide further out of the drying oven 100. This limits the sliding distance of the shelf 200, preventing it from slipping off. If the operator needs to remove the shelf 200 as a whole, the positioning post is moved upward by the drive component, causing it to disengage from the positioning groove, thereby removing the limitation on the slide bar 201. Finally, the slide bar 201 is slid out of the slide rail 300, allowing the shelf 200 to be completely removed from the drying oven 100. This makes the operation more convenient and has greater applicability.
[0027] according to Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the drive assembly includes a limiting frame 400 disposed on the front side of the upper surface of the slide rail 300. A movable plate 500 is slidably disposed inside the limiting frame 400. A positioning post is disposed at the bottom of the movable plate 500. A through groove adapted to the positioning post is opened on the lower surface of the limiting frame 400, and the through groove extends to the inner side of the slide rail 300. The end of the positioning post penetrates the through groove at the bottom of the limiting frame 400. When the slider 201 is located inside the slide rail 300 and the positioning post is not corresponding to the positioning groove, the positioning post cannot descend because the slider 201 is blocked inside the slide rail 300. Therefore, the positioning post is located inside the limiting frame 400. A toggle component is provided on one side of the surface of the limiting frame 400. The toggle component is used to drive the movable plate 500 to slide upward.
[0028] The operator pulls the shelf 200, causing the slider 201 to slide within the slide rail 300. When the positioning groove on the upper part of the slider 201 corresponds to the position of the positioning post, the positioning post has room to move downward. At this time, the weight of the positioning post and the movable plate 500 will cause the positioning post and the movable plate 500 to descend, allowing the positioning post to insert into the positioning groove, thereby limiting and fixing the slider 201, preventing the slider 201 from sliding further outward. If it is necessary to remove the shelf 200, the movable plate 500 and the positioning post are moved upward by the actuating component, causing the positioning post to disengage from the positioning groove. By removing the limitation on the slider 201, the slider 201 can slide out from the slide rail 300, thus removing the shelf 200, making the operation more convenient.
[0029] according to Figure 3 and Figure 4 As shown, the actuating component includes a guide groove 401 formed on one side of the surface of the limiting frame 400, and a handle 504 is slidably disposed in the guide groove 401. One end of the handle 504 is connected to one side of the surface of the movable plate 500.
[0030] When it is necessary to remove the limit on the slider 201, pull the handle 504 upward, so that the handle 504 slides upward along the guide groove 401. The handle 504 drives the movable plate 500 to move upward in sync, thereby driving the positioning post to disengage from the positioning groove.
[0031] according to Figure 3 and Figure 4 As shown, the guide groove 401 has an inverted L-shaped structure, and the movable plate 500 has a corresponding slide groove 503 on one side of the guide groove 401. The end of the handle 504 is slidably disposed in the slide groove 503 on the side wall of the movable plate 500.
[0032] After the worker pulls the handles 504 on both sides and slides them upwards, they slide them into the horizontal groove of the guide groove 401. At this time, the end of the handle 504 slides horizontally along the sliding groove 503 on the side wall of the movable plate 500, so that the handle 504 is engaged in the horizontal position at the top of the guide groove 401, thereby preventing the movable plate 500 from moving downwards and preventing the positioning post from falling automatically. Then, the shelf 200 is taken out, and finally the handle 504 is slid in the opposite direction, so that the handle 504 is disengaged from the horizontal position of the guide groove 401, thereby allowing the movable plate 500 and the positioning post to fall back to their original positions. This allows one worker to complete the removal of the shelf 200, which is convenient and quick.
[0033] according to Figure 4 and Figure 7 As shown, a spring 502 is provided at the upper end of the movable plate 500. The upper end of the spring 502 is fixed to the upper side of the inner wall of the limiting frame 400, and the lower end of the spring 502 is fixed to the upper surface of the movable plate 500.
[0034] When the positioning post is inside the limiting frame 400, the spring 502 is in a compressed state. When the shelf 200 is pulled, when the positioning post is in the position of the positioning groove, the rebound force of the spring 502 and the weight of the positioning post can push the positioning post down, so that the positioning post is tightly locked in the positioning groove to improve stability.
[0035] according to Figure 4 As shown, the surface of the positioning post, and the side facing the opening of the slide rail 300, is set as a slope;
[0036] When the staff needs to install the shelf 200, since the slider 201 is not yet in the slide rail 300, the positioning post will be located inside the slide rail 300. The staff drags the shelf 200, causing the sliders 201 on both sides of the shelf 200 to slide into the opening of the slide rail 300, so that the rear side wall of the slider 201 contacts the inclined surface of the positioning post, thereby driving the positioning post to move upward and enter the limiting frame 400. During the process of the staff pushing the shelf 200 into the drying oven 100, the positioning post will first insert into the positioning groove. Driven by the inclined surface of the positioning post, the staff continues to push the shelf 200, which will cause the positioning post to continue to move upward to disengage from the positioning groove. Then, the staff continues to push the shelf 200, so that the slider 201 can slide completely into the slide rail 300 to complete the installation of the shelf 200.
[0037] according to Figure 3 and Figure 4 As shown, the surface of the handle 504 is provided with anti-slip raised strips;
[0038] The anti-slip ridges make the 504 handle more slip-resistant and prevent it from slipping.
[0039] How to use this utility model:
[0040] When it is necessary to remove the shelf 200 from the drying oven 100 by pulling it a certain distance without removing the shelf 200 as a whole, open the drying oven 100, and then pull the desired shelf 200. The sliders 201 on both sides of the shelf 200 slide within the slide grooves 503. During the sliding process, when the positioning groove on the upper part of the slider 201 corresponds to the position directly below the positioning post, the rebound force of the spring 502 pushes the movable plate 500 and the positioning post downward, causing the positioning post to insert into the positioning groove, thereby limiting the slider 201 to prevent it from sliding out of the slide rail 300, and thus limiting the sliding distance of the shelf 200 to prevent it from falling off. When the operator needs to remove the shelf 200 as a whole, they pull the handle 504 upwards. The handle 504 causes the movable plate 500 and the positioning post to disengage from the positioning groove. Then, they pull the handle 504 horizontally so that it engages with the guide groove 401 in a horizontal position, thus preventing the movable post from sliding down. Then, they can pull the shelf 200 to move the slide bar 201 out of the slide rail 300 to remove the shelf 200. This device can limit the sliding distance of the shelf 200 to prevent it from slipping. At the same time, it can also choose to cancel the limit on the shelf 200, so that the shelf 200 can be removed from the drying oven 100 as a whole. The operation is more convenient and the applicability is stronger.
[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
