[0002] High and low temperature test chambers are widely used in industries such as electronics, chemicals, automotive, and aerospace to simulate the performance of products under different temperature environments. However, during high-temperature resistance testing, there is a risk of explosion for the test objects inside the chamber. In the event of an explosion, not only will the test chamber and the internal test samples be damaged, but it could also cause serious injury to surrounding personnel and equipment.

[0003] Currently, the existing explosion-proof designs of high and low temperature test chambers have many shortcomings, such as poor buffering, slow fire extinguishing speed, and inconvenience in loading and unloading test objects. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An explosion-proof device for a high and low temperature test chamber includes an inner explosion-proof cover and an outer explosion-proof cover, both of which are mounted on a base platform via a shock-absorbing mechanism. A folding platform is hinged to the front of the base platform, and rollers are provided at the bottom of the shock-absorbing mechanism. Both the base platform and the folding platform are provided with wheel grooves for the rollers to move. The inner explosion-proof cover is annular and has through holes on its side walls. A fire extinguishing nozzle is provided at the top of the outer explosion-proof cover. The bottoms of both the inner and outer explosion-proof covers are connected to the shock-absorbing mechanism via threads.

[0007] A transparent viewing window is provided on the folding platform, and the angle between the window and the base platform varies from 90° to 180°.

[0008] Furthermore, the shock absorption mechanism includes two platforms that are spaced apart vertically and arranged in parallel. The two platforms are connected by a vertically placed shock absorber. The upper platform has two concentric threaded grooves, which are used to screw into the bottom of the inner explosion-proof cover and the outer explosion-proof cover, respectively. Rollers are connected to the bottom of the lower platform.

[0009] Furthermore, a storage area is provided at the center of the threaded annular groove.

[0010] Furthermore, the outer explosion-proof cover includes several grid wires connected in a ring, each grid wire including vertical wires and horizontal wires that are vertically turned and connected, the horizontal wires being located above the vertical wires and the center of the intersection of all the horizontal wires being connected to the fire extinguishing nozzle.

[0011] Furthermore, both the inner explosion-proof cover and the wire mesh are connected to threaded rings at their bottoms.

[0012] Furthermore, the transparent window includes a first window located in the middle of the folding table and a second window located at the front end of the folding table, the second window being fan-shaped.

[0013] Furthermore, the first viewing window, the second viewing window, and the inner explosion-proof cover are all made of transparent organic glass.

[0014] Furthermore, the fire extinguishing nozzle includes an upper inlet pipe and several lower outlet pipes connected to it, with the outlets of the outlet pipes facing downwards and radiating outwards.

[0015] Furthermore, the number of shock absorbers is ≥3, and the bottom or side of the base is provided with connecting parts for fixing to the high and low temperature test chamber.

[0016] The beneficial effects of adopting the technical solution of this utility model are:

[0017] 1. The present invention provides an explosion-proof device for a high and low temperature test chamber, which is equipped with a shock-absorbing mechanism to buffer the impact of an explosion and minimize vibration damage to the interior of the high and low temperature test chamber.

[0018] 2. The explosion-proof device for high and low temperature test chambers of this utility model forms a triple protective barrier of inner explosion-proof cover - outer explosion-proof cover - transparent window, which greatly improves the explosion-proof performance and avoids injury to the human body from the explosion and splashing of the tested object.

[0019] 3. The explosion-proof device for a high and low temperature test chamber of this utility model is equipped with a fire extinguishing nozzle that can respond quickly in the early stage of a fire, spray the fire extinguishing agent to the fire area in a timely manner, quickly control the fire, and prevent the fire from spreading and causing a chain explosion reaction.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. The present invention is described in detail using structural schematic diagrams, etc., which are merely examples and should not be construed as limiting the scope of protection of the present invention.

[0030] Please refer to the following: Figures 1-4 An explosion-proof device for a high and low temperature test chamber includes an inner explosion-proof cover 1 and an outer explosion-proof cover 2, both of which are mounted on a base 4 via a shock-absorbing mechanism 3. The bottom or side of the base 4 is provided with a connecting piece 4a for fixing to the internal test space of the high and low temperature test chamber. A folding platform 5 is hinged to the front of the base 4, and the angle between the folding platform 5 and the base 4 varies from 90° to 180°. A roller 6 is provided at the bottom of the shock-absorbing mechanism 3, and both the base 4 and the folding platform 5 are provided with wheel grooves for the roller 6 to move.

[0031] If a fire inside the test chamber is not extinguished in time, it may trigger a chain reaction and cause more serious consequences. Installing fire extinguishing nozzles and extinguishing the fire in time can reduce the temperature, isolate oxygen, prevent the fire from causing an explosion, and ensure the safety of the test chamber and the surrounding environment.

[0032] Specifically, the inner explosion-proof cover 1 is annular with through holes on its sidewalls, and the top of the outer explosion-proof cover 2 is equipped with a fire extinguishing nozzle 2a. The bottoms of both the inner and outer explosion-proof covers 1 and 2 are connected to the shock-absorbing mechanism 3 via threads. The outer explosion-proof cover 2 includes several grid wires 2b connected in a ring. Each grid wire 2b includes vertical wires 2b-1 and horizontal wires 2b-2 that are vertically connected. The horizontal wires 2b-2 are located above the vertical wires 2b-1, and the center of the intersection of all the horizontal wires 2b-2 is connected to the fire extinguishing nozzle 2a. The double-layer explosion-proof cover structure effectively prevents explosive splashes from damaging the inner wall of the high and low temperature test chamber. (Reference) Figure 4 The fire extinguishing nozzle 2a includes an upper inlet pipe 2a-1 and several lower outlet pipes 2a-2. The outlet pipes 2a-2 are arranged with their outlets facing downwards and diverging outwards, so that the extinguishing liquid sprayed from the nozzle can be evenly distributed over a larger area, thereby covering a larger fire extinguishing area, improving fire extinguishing efficiency, extinguishing the fire source more effectively, reducing the possibility of fire spread, and preventing the occurrence of chain explosions.

[0033] On the other hand, specifically, the shock absorption mechanism 3 includes two platforms 3a arranged vertically and parallel to each other. The two platforms 3a are connected by ≥3 vertically placed shock absorbers 3b. When an explosion occurs, these shock absorbers 3b can absorb and dissipate some of the energy generated by the explosion through their own compression deformation, reducing the transmission of the explosion impact to the test chamber and surrounding structures. The bottom of the lower platform 3a is connected to rollers 6, and the upper platform 3a is provided with two concentric threaded grooves. The center of the threaded grooves is provided with a storage area. The bottom of the inner explosion-proof cover 1 and the fence wire 2b are both connected to threaded rings. The two threaded grooves are respectively used to screw into the bottom of the inner explosion-proof cover 1 and the outer explosion-proof cover 2. The threaded connection makes it convenient to replace the inner explosion-proof cover 1 and the outer explosion-proof cover 2 after damage or the expiration of their service life, and the connection is firm and not easily blown away by the explosion impact.

[0034] In this embodiment, a transparent viewing window 5a is provided on the folding table 5. The transparent viewing window 5a includes a first viewing window 5a-1 located in the middle of the folding table 5 and a second viewing window 5a-2 located at the front end of the folding table 5. The first viewing window 5a-1 is rectangular, and the second viewing window 5a-2 is fan-shaped. The first viewing window 5a-1, the second viewing window 5a-2, and the inner explosion-proof cover 1 are all made of transparent plexiglass. Through the transparent viewing window, the operator can clearly observe the test situation inside the test chamber without opening the test chamber, including the state of the test sample. This helps to promptly identify problems that occur during the test, such as whether the sample has undergone abnormal changes or whether the equipment is operating normally, so as to take appropriate measures in a timely manner. The setting of the transparent viewing window not only meets the operator's need to observe the test, but also avoids the safety hazards that may be caused by frequently opening the test chamber door (the test chamber door is also provided with a transparent viewing window), thus ensuring the safety of the test process.

[0035] This utility model discloses an explosion-proof device for a high and low temperature test chamber. During operation, the inner explosion-proof cover 1 and the outer explosion-proof cover 2 can be connected to or separated from the platform 3a by screwing on them. (Refer to reference...) Figure 5 The folding platform 5 folds upwards perpendicular to the base platform 4, forming a triple protective barrier of inner explosion-proof cover 1, outer explosion-proof cover 2, and transparent viewing window 5a, greatly improving explosion-proof performance and preventing injury from exploding and flying debris from the tested object; (Refer to reference...) Figure 6 When the folding table 5 is folded down to be level with the base 4, the roller 6 can be driven to move along the wheel groove, and the inner explosion-proof cover 1 and the outer explosion-proof cover 2 can be moved to the folding table 5 located outside the high and low temperature test chamber, which is convenient for picking up and putting down the test object.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
