Description

Technical Field

[0001] This utility model relates to the field of high temperature test chamber technology, specifically to an automatic opening and closing high temperature test chamber. Background Technology

[0002] High-temperature test chambers are widely used in scientific research and production units in aviation, aerospace, petroleum, chemical, military, shipbuilding, electronics, and communications industries. They are mainly used for tests such as drying, baking, heat treatment, disinfection, and heat preservation of items.

[0003] A search of Chinese patent publication CN 218339822U, "A High-Temperature Test Chamber with Automatic Alarm Function," reveals a housing comprising a shell with multiple heating chambers on its front side. A heating rod is fixedly connected to the right side of the inner wall of each heating chamber, with its right end penetrating the inner wall and fixedly connected to a power interface. The power interface is fixedly connected to the right side of the outer wall of the shell on its left side. An air pipe is fixedly connected to the left side of the inner wall of the heating chamber, with its left end penetrating the inner wall and fixedly connected to the output of a hot air blower. This invention features multiple heating chambers, each with an independently controllable room temperature, allowing for simultaneous testing of the aging degree of samples at different room temperatures, thus improving testing efficiency. Furthermore, the hot air blower's ability to uniformly heat the air within the heating chambers, along with the selection of a motor-driven tray, ensures uniform heating of the samples from multiple sides, enhancing the accuracy of the test.

[0004] In the existing technology, the side of the shelf is fixedly installed to the shell without leaving corresponding deformation space. When the shelf is heated, it will expand. At this time, the shelf is prone to bending, warping or stress conflict with the frame of the box, which can easily cause the shelf to break and shorten the service life of the shelf. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatically opening and closing high-temperature test chamber to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an automatically opening and closing high-temperature test chamber, comprising:

[0007] The high-temperature test chamber body and shelves, wherein the high-temperature test chamber body has movable connecting shelves;

[0008] The anti-deformation and damage component includes a C-shaped groove and a first spring. The C-shaped groove is opened on the inner wall of the middle part of the high temperature test chamber body. One end of the first spring is fixedly connected to both sides of the shelf. The shelf and the first spring are movably connected in the C-shaped groove.

[0009] Furthermore, the gap between both ends of the shelf and the inner wall of the C-shaped groove at the main body of the high-temperature test chamber is three centimeters, and the gap between the rear end of the shelf and the inner wall of the C-shaped groove at the main body of the high-temperature test chamber is four centimeters.

[0010] Furthermore, the height of the C-shaped groove is twice the thickness of the shelf.

[0011] Furthermore, the anti-deformation and damage component also includes a second spring and a slot. The slots are provided at both ends of the rear part of the shelf. One end of the second spring is fixedly connected to the slot, and the second spring is movably connected in the C-shaped groove.

[0012] Furthermore, the anti-deformation and damage component also includes a hexagonal ventilation groove, which is formed through the shelf.

[0013] Furthermore, it also includes a limiting and ejection component, which includes a limiting block, and the limiting blocks are movably connected to both sides of the front of the C-shaped groove in the middle of the high temperature test chamber body.

[0014] Furthermore, the limiting and ejection assembly also includes an L-shaped groove and a hydraulic expansion joint. L-shaped grooves are opened on both sides of the front end of the high-temperature test chamber body. The L-shaped grooves are connected to the C-shaped grooves. The hydraulic expansion joint is fixedly installed in the L-shaped grooves. The bottom of the hydraulic expansion joint is fixedly connected to the limiting block.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, a C-shaped groove is provided in the middle of the main body of the high-temperature test chamber, which leaves a gap between the outer side of the shelf and the main body of the high-temperature test chamber. This gap allows the shelf to accommodate the expansion deformation that occurs when heated, preventing the shelf from bending, warping, or experiencing stress conflicts with the chamber frame. This ensures the shelf's service life. Furthermore, the installed first and second springs can adapt to the expansion deformation of the shelf and simultaneously clamp and limit the shelf, preventing the items on it from shaking due to shelf displacement.

[0017] Based on the aforementioned beneficial effects, the setting of the limiting block at the front of the C-shaped groove further enhances the limiting effect on the shelf; when the hydraulic telescopic device is closed, it drives the limiting block to move upward and disengage from the front of the C-shaped groove. At this time, the squeezing force on the second spring at the rear of the shelf disappears, and the second spring returns to its original state, pushing the shelf forward, thereby accelerating the rate at which items are removed from the shelf after detection.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-6As shown, this utility model is an automatically opening and closing high-temperature test chamber, comprising:

[0032] The high temperature test chamber body 101 and shelf 102, with shelf 102 movably connected in the high temperature test chamber body 101;

[0033] The anti-deformation and damage component includes a C-shaped groove 201 and a first spring 202. A C-shaped groove 201 is opened in the inner wall of the middle part of the high temperature test chamber body 101. One end of the first spring 202 is fixedly connected to both sides of the shelf 102. The shelf 102 and the first spring 202 are movably connected in the C-shaped groove 201.

[0034] The top of the shelf 102 is used to place the item to be inspected. The C-shaped groove 201 provides a guarantee for the movable connection between the shelf 102 and the first spring 202. The first spring 202 provides a guarantee for the clamping limit of the shelf 102.

[0035] The gap between the two ends of the shelf 102 and the inner wall of the C-shaped groove 201 at the main body 101 of the high temperature test chamber is three centimeters, and the gap between the rear end of the shelf 102 and the inner wall of the C-shaped groove 201 at the main body 101 of the high temperature test chamber is four centimeters; the height of the C-shaped groove 201 is twice the thickness of the shelf 102.

[0036] The dimensions of the aforementioned components provide ample space for the deformable parts of the shelf 102 that expand due to heat.

[0037] The anti-deformation and damage component also includes a second spring 203 and a slot 204. The slots 204 are opened at both ends of the rear part of the shelf 102. One end of the second spring 203 is fixedly connected to the slot 204, and the second spring 203 is movably connected in the C-shaped groove 201.

[0038] The slot 204 ensures a secure connection for the second spring 203, and the second spring 203 further enhances the clamping and limiting effect on the shelf 102.

[0039] The anti-deformation and damage component also includes a hexagonal ventilation groove 205, which is provided through the shelf 102;

[0040] The hexagonal ventilation slots 205 ensure uniform airflow inside the high-temperature test chamber body 101 and further accommodate the expansion deformation of the shelf 102.

[0041] Working principle: Place the item to be tested on top of shelf 102, then close the door of the high temperature test chamber body 101. At this time, turn on the control switch of the high temperature test chamber body 101. The high temperature test chamber body 101 generates high temperature, and shelf 102 expands and deforms due to heat. The deformed part moves accordingly at C-shaped groove 201, and pushes the first spring 202 and the second spring 203 to contract.

[0042] Please see Figure 1-6 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The limiting and ejection assembly includes a limiting block 301, which is movably connected to the two sides of the front of the C-shaped groove 201 in the middle of the high temperature test chamber body 101; the limiting and ejection assembly also includes an L-shaped groove 302 and a hydraulic expansion joint 303, with L-shaped grooves 302 opened on both sides of the front of the high temperature test chamber body 101, the L-shaped grooves 302 connecting to the C-shaped groove 201, the hydraulic expansion joint 303 being fixedly installed in the L-shaped grooves 302, and the bottom of the hydraulic expansion joint 303 being fixedly connected to the limiting block 301;

[0044] The L-shaped groove 302 provides space for the secure installation of the hydraulic expansion joint 303, and the hydraulic expansion joint 303 provides kinetic energy for the up-and-down movement of the limit block 301.

[0045] Working principle: First, the hydraulic expansion joint 303 is in the closed state, and the limiting block 301 is located above the front end of the C-shaped groove 201. Then, the shelf 102 and its connected first spring 202 and second spring 203 are inserted into the C-shaped groove 201 to achieve the initial installation of the shelf 102. At this time, the first spring 202 and the second spring 203 are in a moderate deformation and compression state. Then, the hydraulic expansion joint 303 is opened, which drives the limiting block 301 to move down. When the limiting block 301 moves to the front of the shelf 102, the shelf 102 is released to achieve the final installation of the shelf 102. After the item is tested, the hydraulic expansion joint 303 is closed, which drives the limiting block 301 to move up. At this time, under the restoring deformation of the second spring 203, the shelf 102 is pushed forward along the C-shaped groove 201. At this time, the item is moved out of the high temperature test chamber body 101 and then taken out.
