Description

Technical Field

[0001] This utility model belongs to the field of test chamber technology, specifically relating to a high and low temperature test chamber that can be automatically opened, closed and quickly locked. Background Technology

[0002] Environmental simulation test chambers are used to test the operating status of products under different environments. For example, temperature test chambers are used to test the stability of products under different temperature changes. Because the structure and size of test chambers vary depending on the product being tested, some specialized non-standard equipment, such as high and low temperature test chambers, are quite large, with heavy and tall doors. Therefore, manually opening and closing the doors during testing is inconvenient and can easily lead to burns or frostbite. Furthermore, current automated door opening and closing test chambers, such as those using hinged rotating doors, require a drive mechanism at the front opening of the chamber to open and close the door, making it inconvenient to load and unload products. If a lifting door is used, the seal between the chamber and the door is poor, failing to meet the requirements of the test chamber. Therefore, there is an urgent need for a high and low temperature test chamber that automatically opens and closes and can quickly lock the door to ensure a tight seal. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a high and low temperature test chamber that can be automatically opened, closed, and quickly locked, solving the problems of difficulty in manually opening and closing the door, which can easily lead to burns and frostbite, and also solving the problems of inconvenience in loading and unloading products with the automated door and poor sealing of the working chamber in the existing technology.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A high and low temperature test chamber that can be automatically opened, closed and quickly locked includes a working chamber and a refrigeration and heating device connected to the working chamber. A gantry frame is provided at the front end of the working chamber, and a door is also provided at the front end of the working chamber. The two sides of the door are connected to sliders set on the gantry frame through multiple locking cylinders, and the upper end of the door is connected to the gantry frame through a lifting mechanism.

[0006] With the above structural design, the door is connected to the gantry frame through a lifting mechanism, which enables the door to move up and down along the gantry frame to achieve automatic opening and closing. The door and the slider on the gantry frame are connected by a locking cylinder. When the door slides to the front end of the working chamber, the locking cylinder can pull the door to fit against the front end of the working chamber to complete the closing. This not only ensures the smooth up and down movement of the door, but also achieves the sealing and stability of the connection between the door and the working chamber.

[0007] Preferably, the refrigeration and heating device is connected to the working chamber through multiple connection channels to refrigerate or heat the working chamber.

[0008] The above structural design enables the rear cooling and heating devices to quickly cool or heat the working chamber, thus improving cooling or heating efficiency.

[0009] Preferably, the gantry frame is provided with slide rails on both sides, and a slider is slidably mounted on the slide rail. The locking cylinder is fixedly mounted on the slider, and the output rod at the other end of the locking cylinder is fixedly connected to the gate body.

[0010] With the above structural design, the locking cylinder allows the door to be pushed a certain distance from the working chamber when the door is opened, ensuring the stability of the door's vertical movement. When closing, the locking cylinder is used to pull the door closer to the working chamber. This ingenious structural design can quickly lock the door and improve the sealing of the working chamber.

[0011] Preferably, an L-shaped mounting plate is fixedly installed on the slider, the locking cylinder is horizontally mounted on the mounting plate, a corresponding mounting block is provided on the door body, and an L-shaped connecting plate is provided on the locking cylinder. One side of the connecting plate is fixedly connected to the mounting block, and the other side is fixedly connected to the output rod.

[0012] Preferably, the door body is provided with a sealing ring that is resistant to high and low temperatures, and the door body is also provided with a transparent observation window.

[0013] With the above structural design, the sealing ring can improve the sealing performance of the working chamber, while the transparent observation window allows for real-time observation of the components inside the working chamber.

[0014] Preferably, the upper end of the door is provided with multiple fixing hooks, and the fixing hooks on both sides of the door are connected to the gantry frame through an anti-fall mechanism to prevent the door from falling accidentally.

[0015] Preferably, the fall protection mechanism includes a winding device, a wire rope, and a first pulley installed on the upper end of the gantry frame. The winding device is fixedly installed on the upper end of the working chamber. One end of the wire rope is fixedly installed on a fixed hook, the wire rope is slidably mounted on the first pulley, and the other end is retractably mounted inside the winding device.

[0016] The above structural design, with its anti-fall mechanism, ensures that even if a heavy door falls unexpectedly and causes injury or death, thus improving the safety of the test chamber.

[0017] Preferably, the lifting mechanism includes a lifting rope connected to a fixed hook on the door body, a second pulley in the middle of the gantry frame, an installation component at the upper end of the working chamber and the refrigeration and heating device, a third pulley on the installation component, and the lifting rope is slidably mounted on the second and third pulleys and its end is fixedly connected to a drive cylinder below the installation component.

[0018] The above structural design enables the door to rise and fall by using a lifting rope connected to a drive cylinder and in conjunction with a second and third pulley. This lifting mechanism is simple in structure, low in cost, and highly stable.

[0019] Preferably, a three-station force testing machine is provided below the working chamber, and the three stations of the three-station force testing machine are set in the working chamber for applying force to the parts under high temperature or low temperature conditions.

[0020] Preferably, a safety light curtain is provided at the front door of the workshop to provide safety assurance when manually handling parts. During the rising and falling of the door, when the safety light curtain detects a person or object passing through the infrared detection line, the door can be stopped immediately to prevent accidents.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The door of this utility model is connected to the gantry frame through a lifting mechanism, thereby realizing the automatic opening and closing of the door by moving up and down along the gantry frame. The door and the slider on the gantry frame are connected by a locking cylinder. When the door slides to the front end of the working chamber, the locking cylinder can pull the door to fit against the front end of the working chamber to complete the closing. This not only ensures the smooth up and down movement of the door, but also achieves the sealing and stability of the connection between the door and the working chamber. It also has the advantages of small footprint, high degree of automation and labor saving.

[0023] 2. This utility model, through the design of the anti-fall mechanism, can ensure that in the event of an accidental fall of a heavy door causing personal injury or death, thus improving the safety of the test chamber.

[0024] 3. The lifting mechanism of this utility model connects the door body and the drive cylinder through a lifting rope. Therefore, the up and down movement of the door body can be achieved by setting the formation of the drive cylinder, thereby achieving precise opening and closing of the door body.

[0032] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Please see Figures 1 to 4A high and low temperature test chamber with automatic opening, closing, and rapid locking includes a working chamber 1 and a cooling and heating device 2 connected to the working chamber 1. The cooling and heating device 2 is connected to the working chamber 1 through multiple connecting channels 7 to cool or heat the working chamber. A gantry frame 3 is provided at the front end of the working chamber 1, and a door 4 is also provided at the front end of the working chamber 1. The two sides of the door 4 are connected to sliders 6 set on the gantry frame 3 through multiple locking cylinders 5. The upper end of the door 4 is connected to the gantry frame 3 through a lifting mechanism. A safety light curtain 12 is provided at the front door 4 inside the working chamber 1. During the rising and falling of the door 4, when the safety light curtain 12 detects a person or object passing through the infrared detection line, the door 12 can be stopped immediately to prevent accidents. In this utility model, because the door 4 is large in size and weight, it is difficult to open and close it manually. Therefore, the door 4 is driven by the lifting mechanism and moves up and down along the gantry frame 3 to achieve automatic opening and closing. Moreover, the up and down movement method not only does not occupy space, but also facilitates the loading and unloading of parts. Furthermore, by using a locking cylinder 5 to connect the door body 4 and the slider 6 of the gantry frame 3, the door body 4 can be pushed open a certain distance when it is opened, thus facilitating its upward movement. When the door body 4 moves down to the working chamber 1 and needs to be closed, the locking cylinder 5 only needs to pull the door body 4 close to and fit it against the working chamber 1 to complete the closure, thereby achieving the sealing effect of the test chamber.

[0035] The specific structure of this utility model is as follows:

[0036] Please continue reading. Figures 1 to 4 The gantry frame 3 has slide rails 3a on both sides, and sliders 6 are slidably mounted on the slide rails 3a. Locking cylinders 5 are fixedly mounted on the sliders 6, and the output rod 5a at the other end of the locking cylinder 5 is fixedly connected to the door body 4. An L-shaped mounting plate 6a is fixedly mounted on the slider 6, and the locking cylinder 5 is horizontally mounted on the mounting plate 6a. A mounting block 4a is correspondingly provided on the door body 4, and an L-shaped connecting plate 5b is provided on the locking cylinder 5. One side of the connecting plate 5b is fixedly connected to the mounting block 4a, and the other side is fixedly connected to the output rod 5a. In this embodiment, four locking cylinders 5 are designed, respectively located on both sides of the door body 4. Furthermore, the front end of each locking cylinder 5 has a double output rod 5a design, which ensures stability with the connecting plate 5b.

[0037] Please see Figure 2 Furthermore, the door body 4 is provided with a high-temperature and low-temperature resistant sealing ring 8, and the door body 4 is also provided with a transparent observation window 4b, which is made of a high-temperature and low-temperature resistant material.

[0038] Please continue reading Figure 1 and Figure 4The upper end of the door body 4 is provided with multiple fixing hooks 4d, and the fixing hooks 4d on both sides of the door body 4 are connected to the gantry frame 3 through a fall prevention mechanism 9 to prevent the door body 4 from falling accidentally. The fall prevention mechanism 9 includes a winding device 9a, a steel wire rope 9b, and a first pulley 9c mounted on the upper end of the gantry frame 3. The winding device 9a is fixedly mounted on the upper end of the working chamber 1. One end of the steel wire rope 9b is fixedly mounted on the fixing hooks 4d, and the steel wire rope 9b is slidably mounted on the first pulley 9c. The other end is retractable into the winding device 9a. The design principle of the fall prevention mechanism 9 in this embodiment is the same as that of a car seat belt, therefore, it will not be described in more detail here.

[0039] The lifting mechanism includes a lifting rope 10a connected to a fixed hook 4d on the door body 4, a second pulley 10b in the middle of the gantry frame 3, and a mounting component 10c at the upper end of the working chamber 1 and the refrigeration and heating device 2. The mounting component 10c is designed as a T-shaped structure with both ends fixed and a through hole 10f in the middle. A third pulley 10d is mounted on the mounting component 10c. The lifting rope 10a is slidably mounted on the second pulley 10b and the third pulley 10d, and its end passes through the through hole 10f and is fixedly connected to the drive cylinder 10e below the mounting component 10c. In this embodiment, to ensure the stability of the door body 1's vertical movement, the second pulley 10b is positioned directly above the lower fixed hook 4d, thereby ensuring that the lifting rope 10a vertically pulls the door body 4 up and down, thus ensuring the stability of the door body 4's movement.

[0040] The high and low temperature test chamber can be used in conjunction with different equipment. For example, a three-station force machine 11 is provided below the working chamber 1, and the three stations of the three-station force machine 11 are set in the working chamber 1 for applying force to the parts under high or low temperature conditions.

[0041] The working principle of this utility model is as follows:

[0042] When high and low temperature tests are required on parts, firstly, when it is necessary to open door 1, locking cylinder 5 pushes door 1 outward a certain distance and disengages it from chamber 1. Then, drive cylinder 10e pulls the lifting rope 10a downward, which in turn moves door 1 upward along slide rail 3a to the stroke specified by drive cylinder 10e. At this point, door 1 is fully open. Then, parts can be placed inside chamber 1 manually or by robot to prepare for testing. Next, drive cylinder 10e moves upward, and door 4 moves downward along slide rail to the front end of chamber 1. Drive cylinder 10e then completes its stroke and stops. At this point, the output rod 5a of locking cylinder 5 on the side of door 4 pulls door 4 closer to the front end of chamber 1 until it is closed. Finally, the high and low temperature test can begin. After the test is completed, the process can be repeated. This invention can automatically move the door 4 up and down through the lifting mechanism, and lock the door 4 to the working chamber 1 through the locking cylinder 5 connected to the door 4, thereby improving the sealing of the working chamber 1. Therefore, this invention has the functions of automatic opening and closing and quick locking of the test chamber.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model. Other devices that are the same as or similar to these devices are all within the protection scope of this utility model.
