It can adjust the positions of multiple receiving seats according to explosion-proof glasses of different sizes, which makes the device applicable to explosion-proof glasses of various specifications. Whether it is a small special explosion-proof glass or a large building explosion-proof glass, the effective support can be achieved by adjusting the positions of the receiving seats, greatly improving the versatility of the equipment, reducing the cost and time required for replacing or re-designing the support device due to different glass sizes, truly simulating the state of the explosion-proof glass during actual installation, and obtaining more reliable and valuable results.

[0018] 3. Replace the detachable pressing head according to the detection needs to simulate the pressure application situations in different cases, such as a conical detachable pressing head and a frustum-shaped detachable pressing head, to simulate the pressure application of different objects.

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a lightweight multi-chamber hollow explosion-proof glass explosion-proof test device, including an instrument main body 1, an electric push rod 2 is arranged at a corresponding position on the top of the instrument main body 1, and a horizontally preset adjustment frame 3 is arranged at the bottom end of the piston rod of the electric push rod 2; A position adjustable seat 4 is slidably installed in a groove opened on the horizontally preset adjustment frame 3, and the position adjustable seat 4 slides axially in the horizontally preset adjustment frame 3; A position adjustable seat 4 is slidably installed in a groove opened on the horizontally preset adjustment frame 3, and the position adjustable seat 4 slides axially in the horizontally preset adjustment frame 3. This design brings significant flexibility and convenience to the explosion-proof glass detection work. The groove in the horizontally preset adjustment frame 3 is formed by a high-precision processing technology, and the inner wall is finely polished, with extremely low surface roughness, which can effectively reduce the frictional resistance when the position adjustable seat 4 slides, ensuring a smooth and stable sliding process. Wear-resistant guide rails are provided on both sides of the groove in the horizontally preset adjustment frame 3, which are precisely matched with the guide grooves on both sides of the position adjustable seat 4, not only playing a good guiding role, but also enhancing the stability of the position adjustable seat 4 during the sliding process, preventing it from shifting or shaking, thereby ensuring the accuracy of the detection work.

[0034] A clamping plate type fixing seat 5 is fixedly installed at the center position of the bottom of the position adjustable seat 4, and different specifications of detachable pressing heads 6 are movably installed in the clamping plate type fixing seat 5; A clamping plate type fixing seat 5 is firmly and fixedly installed at the center position of the bottom of the position adjustable seat 4. This fixing seat adopts a high-precision processing technology to ensure a tight and stable connection between it and the position adjustable seat 4, and can withstand various forces generated during the detection process. Inside the clamping plate type fixing seat 5, a precise movable installation structure is designed, enabling different specifications of detachable pressing heads 6 to be easily and firmly installed therein. This movable installation method not only ensures the stability of the detachable pressing head 6 during operation, but also facilitates the operation when different specifications of pressing heads need to be replaced, greatly improving the efficiency of the detection work.

[0035] The clamping plate type fixing seat 5 is composed of a two-piece structure, and two groups of fixing buckles 7 are installed on the clamping plate type fixing seat 5, and connecting bolts 8 are provided on each group of fixing buckles 7 for fixation.

[0036] The two-piece structure is more convenient for assembly and disassembly, which can effectively reduce the time cost of installation and maintenance. On the clamping plate type fixing seat 5, two groups of fixing buckles 7 are symmetrically installed. The design of each group of fixing buckles 7 fully considers the mechanical principle and can evenly distribute the pressure to ensure that the detachable pressure head 6 will not loosen or shift after being fixed. Each group of fixing buckles 7 is provided with a connecting bolt 8 for fixing. These connecting bolts 8 are made of high-strength alloy materials and have excellent anti-fatigue and anti-corrosion properties. During the installation process, the operator can use professional tools to precisely control the tightening degree of the connecting bolts 8, so as to ensure that the fixing effect of the clamping plate type fixing seat 5 on the detachable pressure head 6 reaches the best state.

[0037] At both ends of the horizontally preset adjusting frame 3, there are limit end caps 9 provided for limiting the movement of the position adjustable seat 4.

[0038] When the position adjustable seat 4 approaches both ends of the adjusting frame during the sliding process, the limiting surface of the limit end cap 9 will contact the corresponding part of the position adjustable seat 4 to prevent it from continuing to move outwards, thus avoiding the position adjustable seat 4 from sliding out of the horizontally preset adjusting frame 3 and ensuring the safety and stability of the operation of the entire device.

[0039] One side of the horizontally preset adjusting frame 3 is designed with an opening, and a positioning scale bar 10 is provided at this position for comparing the moving position of the horizontally preset adjusting frame 3; When it is necessary to adjust the position of the horizontally preset adjusting frame 3, the operator can precisely control the moving distance of the adjusting frame by observing the position of the position adjustable seat 4 relative to the scale on the positioning scale bar 10. When detecting explosion-proof glass of different sizes, according to the detection requirements, it is necessary to move the position adjustable seat 4 to a specific position. At this time, the positioning scale bar 10 becomes an important reference tool. The operator can find the corresponding scale mark on the positioning scale bar 10 according to the size of the explosion-proof glass and the position of the detection point, and then accurately move the position adjustable seat 4 to this position by operating the device, so as to achieve precise control of the detection position.

[0040] On one side of the position adjustable seat 4 corresponding to the positioning scale bar 10, there is a fixed clamping plate 11. A locking bolt 12 is threadedly connected to the fixed clamping plate 11, and the locking bolt 12 supports at the corresponding position on the outer wall of the positioning scale bar 10.

[0041] The fixed buckle plate 11 is processed with precise threaded holes for threaded connection with the locking bolt 12. The locking bolt 12 is also made of high-quality alloy material, with high thread precision and tight fit. When it is necessary to fix the position of the position adjustable seat 4 on the horizontal preset adjusting frame 3, the operator can rotate the locking bolt 12 to make it gradually move towards the direction of the positioning scale bar 10. As the locking bolt 12 is continuously screwed in, its end will gradually support at the corresponding position on the outer wall of the positioning scale bar 10.

[0042] During this process, a frictional force will be generated between the locking bolt 12 and the outer wall of the positioning scale bar 10, and this frictional force can effectively prevent the axial sliding of the position adjustable seat 4 within the horizontal preset adjusting frame 3. Due to the self-locking characteristic of the threaded connection between the locking bolt 12 and the fixed buckle plate 11, once the locking bolt 12 is tightened to the appropriate degree, the position adjustable seat 4 will be firmly fixed in the current position, ensuring that there will be no displacement during the subsequent detection process, thus guaranteeing the accuracy and reliability of the detection results.

[0043] The detachable pressing head 6 is composed of a threaded part and an extrusion part, and the threaded part of the detachable pressing head 6 is threadedly connected to the clamping plate type fixing seat 5.

[0044] The cross-section of the position adjustable seat 4 is in the shape of an I-beam, and the upper half of the position adjustable seat 4 is located within the horizontal preset adjusting frame 3, while the lower half of the position adjustable seat 4 is located outside the horizontal preset adjusting frame 3.

[0045] On the front of the instrument main body 1, a U-shaped guide frame 13 is provided, and a protective baffle 14 is vertically movably installed on the U-shaped guide frame 13. A handle 15 is provided on the front of the protective baffle 14; On the front of the instrument main body 1, an embedded block 16 is provided, and the shape of the embedded block 16 is the same as the shape of the slot on the back of the protective baffle 14.

[0046] The protective baffle 14 plays an important protective role in the device, and can effectively block the flying objects or fragments that may be generated during the detection process, protecting the safety of the operator and the surrounding equipment. When it is necessary to move the protective baffle 14, the operator only needs to dock the slot on the back of the protective baffle 14 with the embedded block 16 on the front of the instrument main body 1. Since the shapes of the two are the same, the embedded block 16 can be smoothly embedded into the slot on the back of the protective baffle 14.

[0047] On the top of the instrument main body 1, an auxiliary mounting plate 17 is provided, and a connecting seat 18 is provided between the auxiliary mounting plates 17 for fixed connection. The electric push rod 2 is rotatably connected to the middle position of the connecting seat 18; One end of the auxiliary mounting plate 17 close to the connecting seat 18 is located below the connecting seat 18.

[0048] At the bottom of the inner wall of the instrument main body 1, there is an installation base 19, and on both sides of the instrument main body 1, there are side waste discharge ports 20.

[0049] On both sides of the instrument main body 1, there are symmetrically arranged side waste discharge ports 20. The design of these side waste discharge ports 20 fully considers the waste treatment problems that may occur during the explosion-proof glass detection process. The sizes of the side waste discharge ports 20 are reasonably planned, which can not only ensure the smooth discharge of waste but also not be too large to affect the structural strength of the instrument main body 1. The opening part adopts a smooth transition design, avoiding the situation of waste getting stuck or scratched during the discharge process.

[0050] Above the installation base 19, there is a first slide rail 21. One end of the first slide rail 21 is provided with a first stepping motor 22. A left - right - hand threaded lead screw 23 is rotatably connected to the output shaft of the first stepping motor 22, and the left - right - hand threaded lead screw 23 is rotatably connected to the first slide rail 21; A second slide rail 24 is movably installed in the first slide rail 21. At the bottom of the second slide rail 24, there is a slider threadedly connected to the left - right - hand threaded lead screw 23. One end of the second slide rail 24 is provided with a second stepping motor 25. A left - right - hand threaded lead screw 23 is threadedly connected to the output shaft of the second stepping motor 25. This left - right - hand threaded lead screw 23 is rotatably connected to the second slide rail 24, and this left - right - hand threaded lead screw 23 is threadedly connected to a slidable seat 26 located in the second slide rail 24. At the top of the slidable seat 26, there is a receiving seat 27, and an explosion - proof glass 28 is placed between the receiving seats 27.

[0051] By precisely controlling the first stepping motor 22 and the second stepping motor 25, the position of the receiving seat 27 can be flexibly adjusted according to the different sizes of the explosion - proof glass 28, ensuring that the receiving seat 27 can accurately support the four sides of the explosion - proof glass 28 and truly simulate the actual installation state of the explosion - proof glass 28. In the actual explosion - proof glass detection work, explosion - proof glasses of different specifications need to be accurately supported and fixed to ensure the accuracy and reliability of the detection results. The adjustable receiving seat 27 of this device can adapt to explosion - proof glasses of various sizes, greatly improving the versatility and applicability of the detection equipment. For example, for a small explosion - proof glass, by adjusting the first stepping motor 22 and the second stepping motor 25, the receiving seats 27 are made closer to firmly support the glass; for a large explosion - proof glass, the receiving seats 27 can be adjusted to a suitable position to achieve full - scale support for the glass. This flexible adjustment function enables the detection work to be carried out efficiently and accurately, providing a strong guarantee for the quality detection of explosion - proof glass.

[0052] There are four receiving seats 27, and the four receiving seats 27 are distributed in a circular array.

[0053] On the outer bearing seat 27, there is a U-shaped buckle 29. A structure composed of a telescopic rod 31 and a telescopic clamping block 30 is movably installed on the U-shaped buckle 29. A spring 32 is movably sleeved outside the telescopic rod 31, and the spring 32 applies a reverse elastic force to the telescopic clamping block 30.

[0054] Working principle: First step: Pull the handle 15 upward. The handle 15 drives the protective baffle 14 to move vertically upward within the U-shaped guide frame 13. When the protective baffle 14 moves upward, the protective baffle 14 will first press on the inner embedded block 16, causing the inner embedded block 16 to deform. Then, the groove on the back of the protective baffle 14 cooperates with the inner embedded block 16 to achieve the fixation of the protective baffle 14 after movement. According to the size of the explosion-proof glass 28, adjust the positions of multiple bearing seats 27. Drive the corresponding left and right thread screw rods 23 to rotate through the first stepping motor 22 to adjust the positions of the two second sliding rails 24 and change the relative distance between the two second sliding rails 24. Then, drive the corresponding second stepping motor 25 to make the second stepping motor 25 drive the corresponding left and right thread screw rods 23 to rotate. Through the rotation of the left and right thread screw rods 23, drive the corresponding slidable seat 26 to move, thereby driving the corresponding bearing seat 27 to move. Through the cooperation of the movement of the slidable seat 26 and the second sliding rail 24, change the distance between the four bearing seats 27 to ensure that the four bearing seats 27 can support around the explosion-proof glass 28 to simulate the installation of the explosion-proof glass 28. When the explosion-proof glass 28 is installed, the lower surface of the explosion-proof glass 28 will first contact the telescopic clamping block 30 and press on the telescopic clamping block 30. After being pressed, the telescopic clamping block 30 will retract into the U-shaped buckle 29, thereby realizing the installation of the explosion-proof glass 28. After the installation of the explosion-proof glass 28 is completed, the telescopic clamping block 30 is no longer under pressure. When the telescopic clamping block 30 is under pressure, it drives the spring 32 to deform. When the telescopic clamping block 30 is not under pressure, the spring 32 applies an elastic force to the telescopic clamping block 30 to drive the telescopic clamping block 30 to reset, realizing the fixation of the explosion-proof glass 28 after installation.

[0055] Second step: Replace the detachable pressure head 6 according to the needs of detection to simulate the pressure application in different situations, such as a conical detachable pressure head 6 and a frustum-shaped detachable pressure head 6, to simulate the pressure application on different objects. After replacement, rotate the threaded part of the detachable pressure head 6 within the clamping plate fixing seat 5 to achieve the installation and fixation of the detachable pressure head 6, and through the presence of the connecting bolt 8, tighten the clamping plate fixing seat 5 to ensure the installation and fixation of the detachable pressure head 6.

[0056] Step 3: Adjust the position of the structure composed of the position adjustable seat 4 and the detachable pressing head 6 as needed to apply pressure to different parts of the explosion-proof glass 28. Change the position of the position adjustable seat 4 by sliding the position adjustable seat 4 in the horizontally preset adjusting frame 3. After the position adjustable seat 4 is adjusted to a suitable position, rotate the locking bolt 12 on the fixed buckle plate 11 to fix the position adjustable seat 4. After the position adjustable seat 4 is fixed, drive the horizontally preset adjusting frame 3 to descend by the piston rod of the electric push rod 2, so that the detachable pressing head 6 contacts the explosion-proof glass 28, apply pressure to the explosion-proof glass 28, and detect the explosion resistance of the explosion-proof glass 28. Further change the position of the position adjustable seat 4 by rotating the electric push rod 2 on the connecting seat 18 to realize the pressure application detection of different positions of the explosion-proof glass 28.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
