Description

Technical Field

[0001] The utility model relates to the technical field of drying box placing racks, and more specifically, to a placing rack for an infrared drying box. Background Art

[0002] Infrared drying ovens heat and dry objects through infrared heating. In the product quality inspection industry, they are usually used to heat and dry containers such as glass beakers and conical flasks, which are convenient to use. In actual use, infrared drying ovens usually use a piece of stainless steel mesh to support the items that need to be dried. In some drying ovens, in order to be able to hold more items, multiple stainless steel meshes are generally placed in the drying oven chamber to achieve the purpose of drying items in batches. However, these stainless steel meshes are usually fixed, and the distance between two adjacent stainless steel meshes cannot be adjusted, making it difficult to support different items.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0027] See also Figure 1-6 The utility model is a placement rack for an infrared drying box, comprising four support plates 1 and two rectangular frames 2. The four support plates 1 are arranged vertically, and the four corners of the two rectangular frames 2 are respectively connected to the upper and lower ends of the four support plates 1 to form a cubic frame body. Universal wheels 3 are provided on the four corners of the rectangular frame 2 located at the bottom. The universal wheels 3 are used to support the entire placement rack, which can be conveniently dragged in the drying box 12, and the disassembly and assembly is more labor-saving and convenient. The two sides of the rectangular frame 2 located at the top are threadedly connected with anti-top components 4, and the placement rack is fixed with the anti-top components 4 for easy disassembly and assembly; a support net 5 is movably placed on the top of the rectangular frame 2 located at the bottom, and the two sides of the support net 5 are in contact with the inner side of the support plate 1. The support net 5 is a stainless steel net. The net 5 serves as a reference stainless steel net and does not need to be adjusted. A plurality of groups of limit components 6 are provided on the inner sides of the four support plates 1 above the support net 5 and are equidistantly distributed along their height direction. The support net 5 is movably placed on the top of at least two groups of limit components 6 to form a multi-layer placement rack for placing more items. Each group of limit components 6 includes four limit platforms 61 of the same height. The four limit platforms 61 are horizontally slidably inserted in the four support plates 1 so that the limit platforms 61 can move in and out of the support plates 1. The upper and lower side surfaces of the limit platforms 61 are both inclined surfaces to ensure that the support net 5 can slide up and down and squeeze the limit platforms 61. In addition, the support plates 1 corresponding to each limit platform 61 are provided with elastic components that can push the limit platforms 61 out of the support plates 1 to support the support net 5.

[0028] The placement rack of the utility model has a support net 5 that is movably placed in a cubic frame, and the support net 5 can be moved or taken out at any time. In actual use, the support net 5 can be directly pulled up and down according to the height of the article, and the support net 5 squeezes the limit platform 61 to retract it into the support plate 1. When the support net 5 passes over the limit platform 61, the limit platform 61 is pushed out under the elastic force of the elastic component, and can support the support net 5 again, so that the distance between two adjacent stainless steel nets can be quickly and conveniently adjusted, thereby effectively improving work efficiency. After the placement rack is placed in the drying box 12, it will be supported by the universal wheel 3, and the anti-top component 4 is used to push the top of the inner cavity of the drying box 2 to achieve fixed installation of the placement rack. When cleaning and maintenance are needed, the anti-top component can be loosened to pull the placement rack out, which is convenient for disassembly and maintenance and very convenient to use.

[0029] Preferably, the reverse top assembly 4 includes a reverse top screw 41, a pad 42 and a knob 43, wherein the reverse top screw 41 is threadedly connected to the middle position of the rectangular frame 2, the pad 42 is installed at one end of the reverse top screw 41 above the rectangular frame 2 through a bearing, and the knob 43 is fixed to the other end of the reverse top screw 41 below the rectangular frame 2. When installing the placement rack, put the placement rack into the drying box 12, and then turn the knob 43 to drive the pad 42 to move upward, and fix it by using the pad 42 to reverse the top of the inner cavity of the drying box 12. When disassembling, loosen the reverse top screw 41, which is very convenient to operate. Furthermore, the outer wall of the knob 43 is provided with anti-slip grooves to facilitate the rotation of the knob 43.

[0030] Preferably, the elastic component includes a telescopic column 62 and a spring 63, wherein a slide groove 64 is provided in the support plate 1, the slide groove 64 is arranged horizontally, the telescopic column 62 is installed in the slide groove 64, and the two ends of the telescopic column 62 are respectively connected to the bottom of the slide groove 64 and the limit platform 61, the spring 63 is sleeved on the periphery of the telescopic column 62, and the two ends of the spring 63 are respectively connected to the bottom of the slide groove 64 and the limit platform 61, and the elastic force of the spring 63 is selected according to the maximum weight that the support net needs to bear, and the force greater than the maximum weight is sufficient. In a natural state, the spring 63 pushes out the limit platform 61, so that the inclined surfaces on the upper and lower sides intersect with the inner side surface of the support plate 1. When the support net 5 slides up and down, its outer edge directly squeezes the inclined surface of the limit platform 61, so that the limit platform 61 retracts into the slide groove 64, and the spring 63 is squeezed. After the support net 5 passes over the outer end surface of the limit platform 61, the spring 63 pushes out the limit platform 61, realizing automatic pop-up support for the support net 5.

[0031] Preferably, transverse reinforcing ribs 7 and oblique reinforcing ribs 8 are provided on both sides of the two rectangular frames 2. There are two oblique reinforcing ribs 8 in total, and the two oblique reinforcing ribs 8 are cross-arranged. By setting the transverse reinforcing ribs 7 and the oblique reinforcing ribs 8, not only the structural strength of the placement rack can be improved, but also the objects can be limited to prevent the objects from falling from both sides.

[0032] Preferably, a through hole 9 extending left and right is opened on one of the support plates 1 located on the front side, and the through hole 9 extends along the upper and lower ends of the support plate 1, and a baffle 10 is slidably inserted in the through hole 9, and a pull plate 11 is connected to the baffle 10 on the outside of the support plate 1 to facilitate pulling out the baffle 10.

[0033] The placement rack of the utility model is provided with a slidable baffle 10 on a support plate 1 on the front side. After the placement rack is installed in the drying box 12 and the support net 5 is placed in the placement rack, the baffle 10 can be pushed to the middle position of the placement rack. At this time, the baffle 10 will block the front side of the support net 5. Such a structure can prevent the support net 5 from being taken out when taking and placing items. When the support net 5 needs to be taken out, the baffle 10 can be pushed outward to release the limit, which is very convenient to use.

[0034] Preferably, the outer wall of the baffle 10 fits with the inner wall of the through hole 9 to increase the friction between the two and prevent the baffle 10 from sliding automatically. The width of the baffle 10 is greater than the width of the support plate 1 to ensure that the baffle 10 can limit the support net after being pushed out.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
