[0036] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0037] The energy absorbing connecting seat of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figures 1 to 4 As shown, the utility model provides an energy-absorbing connecting seat, which includes a mounting assembly and a buffer module. The mounting assembly includes a mounting frame 10 and a connecting frame 20 for respectively corresponding to the target protective object and the explosion-proof protective structure; the buffer module includes an energy-absorbing spring 30 and two connecting rod assemblies 40 symmetrically arranged between the mounting frame 10 and the connecting frame 20, one end of the two connecting rod assemblies 40 is coaxially hinged to the mounting frame 10, and the other end is coaxially hinged to the connecting frame 20, and the two ends of the energy-absorbing spring 30 are respectively connected to the two connecting rod assemblies 40 in a one-to-one manner, and the connecting rod assembly 40 is used to fold when the explosion-proof protective structure is impacted, and drive the energy-absorbing spring 30 to stretch.

[0039] Specifically, the energy absorbing connecting seat is used to be arranged between the target protective object and the anti-explosion protective structure to connect the target protective object and the anti-explosion protective structure. The energy absorbing connecting seat includes a mounting frame 10, a connecting frame 20, an energy absorbing spring 30 and two connecting rod assemblies 40. The mounting frame 10 and the connecting frame 20 are spaced apart. The two connecting rod assemblies 40 are both arranged between the mounting frame 10 and the connecting frame 20 and are symmetrically arranged. The two ends of each connecting rod assembly 40 are respectively hinged to the mounting frame 10 and the connecting frame 20. The two ends of the energy absorbing spring 30 are respectively connected to the two connecting rod assemblies 40. The mounting frame 10 is connected to the target protective object. The connecting frame 20 is connected to the explosion-proof protective structure. When the explosion-proof protective structure is subjected to the impact of the explosion, it will move toward the target protective object and transmit the shock wave and vibration to the connecting rod assembly 40, so that the connecting rod assembly 40 switches from the unfolded state to the folded state to play a role in buffering and vibration reduction, preventing the impact force from being directly transmitted to the target protective object, and the two connecting rod assemblies 40 can cooperate with the stretching energy-absorbing spring 30 when folding, so that the energy-absorbing spring 30 absorbs the impact energy, preventing the shock wave and vibration from being transmitted to the target protective object and damaging the target protective object, thereby improving the explosion-proof stability and reliability.

[0040] In an embodiment of the present utility model, each connecting rod assembly 40 includes a first connecting rod 41 and a second connecting rod 42 hinged to the first connecting rod 41, and the end of the first connecting rod 41 of the two connecting rod assemblies 40 away from the second connecting rod 42 is coaxially hinged to the first hinge point 14 of the mounting frame 10, and the end of the second connecting rod 42 of the two connecting rod assemblies 40 away from the first connecting rod 41 is coaxially hinged to the second hinge point 24 of the connecting frame 20, and the third hinge point 44 of the first connecting rod 41 and the second connecting rod 42 is used to be set outward away from the first hinge point 14 and the second hinge point 24 under the elastic support of the energy absorption spring 30.

[0041] like Figures 1 to 4As shown, in the two connecting rod assemblies 40, one ends of the two first connecting rods 41 are hinged to each other and are both hinged to the first hinge point 14 on the mounting frame 10, the other ends of the two first connecting rods 41 are respectively hinged to one end of the two second connecting rods 42 and have a third hinge point 44 respectively, and the other ends of the two second connecting rods 42 are hinged to each other and are both hinged to the second hinge point 24 on the connecting frame 20, and the elastic supporting force of the energy absorption spring 30 acts on the two third hinge points 44 respectively, so that the third hinge points 44 of the first connecting rod 41 and the second connecting rod 42 are arranged outward relative to the first hinge point 14 and the second hinge point 24. When subjected to an explosion impact, the explosion-proof protective structure will move toward the target protective object and transmit the shock wave and vibration to the connecting rod assembly 40, so that the second connecting rod 42 folds toward the first connecting rod 41 to reduce the impact of the explosion-proof protective structure on the target protective object, and the first connecting rod 41 and the second connecting rod 42 can cooperate with the stretching energy-absorbing spring 30 when folding, so that the elastic restoring force of the energy-absorbing spring 30 acts on the explosion-proof protective structure through the first connecting rod 41 and the second connecting rod 42. The explosion-proof protective structure moves back and forth under the elastic restoring force and the explosion impact force, so that both the energy-absorbing spring 30 and the explosion-proof protective structure can absorb the impact energy, suppress the transmission of the explosion shock wave, and improve the vibration isolation protection effect; and the third hinge point 44 is arranged outward relative to the first hinge point 14 and the second hinge point 24, so that when the first connecting rod 41 and the second connecting rod 42 are folded, the third hinge points 44 of the two connecting rod assemblies 40 can move away from each other to prevent folding interference between the two connecting rod assemblies 40, and the structural design is reasonable.

[0042] Furthermore, each connecting rod assembly 40 further includes a connecting column 43, which passes through the third hinge point 44 of the first connecting rod 41 and the second connecting rod 42, and the two ends of the energy absorbing spring 30 are respectively connected to the connecting columns 43 of the two connecting rod assemblies 40 in a one-to-one correspondence. Figures 1 to 4 As shown, the connecting column 43 passes through one end of the first connecting rod 41 away from the mounting frame 10 and one end of the second connecting rod 42 away from the connecting frame 20, so that the first connecting rod 41 and the second connecting rod 42 are hinged through the connecting column 43. In the two connecting rod assemblies 40, the energy absorption spring 30 is arranged between the two connecting rod assemblies 40, and one end of the energy absorption spring 30 is connected to the connecting column 43 of one of the connecting rod assemblies 40, and the other end of the energy absorption spring 30 is connected to the connecting column 43 of the other connecting rod assembly 40, so that the two connecting columns 43 can cooperate to stretch the energy absorption spring 30, and then the elastic restoring force of the energy absorption spring 30 acts on the first connecting rod 41, the second connecting rod 42 and the anti-explosion protection structure to perform local resonance. Both the energy absorption spring 30 and the anti-explosion protection structure can absorb impact energy, suppress the transmission of explosion shock waves, and improve the vibration isolation protection effect.

[0043] In the embodiment of the present utility model, the connecting column 43 includes a mounting portion 431, a first connecting portion 432, and a second connecting portion 433. The mounting portion 431 passes through the third hinge point 44 of the first connecting rod 41 and the second connecting rod 42. The first connecting portion 432 and the second connecting portion 433 are respectively provided at both ends of the mounting portion 431. The number of the energy absorbing springs 30 is set to two, and the two energy absorbing springs 30 are respectively connected to the first connecting portion 432 and the second connecting portion 433 in a one-to-one correspondence. Figures 1 to 4 As shown, the first connecting rod 41 and the second connecting rod 42 are hinged by the mounting portion 431, and the two energy absorbing springs 30 are respectively arranged on both sides of the connecting rod assembly 40, wherein the two ends of one energy absorbing spring 30 are respectively connected to the two first connecting portions 432, and the two ends of the other energy absorbing spring 30 are respectively connected to the two second connecting portions 433, so that the two first connecting portions 432 can cooperate to stretch one of the energy absorbing springs 30, and the two second connecting portions 433 can cooperate to stretch the other energy absorbing spring 30. Both energy absorbing springs 30 can absorb impact energy when the connecting rod assembly 40 is folded, further improving the ability to absorb shock waves and improving the stability of the structure.

[0044] Furthermore, the energy absorbing spring 30 includes an energy absorbing portion 31 and two connecting portions 32 respectively provided at both ends of the energy absorbing portion 31. The first connecting portion 432 and the second connecting portion 433 are both provided with connecting holes 434 for the connecting portions 32 to extend into. Figures 1 to 4 As shown, the two hanging parts 32 of one energy absorbing spring 30 are respectively hung in the hanging holes 434 of the two first connecting parts 432, and the two hanging parts 32 of the other energy absorbing spring 30 are respectively hung in the hanging holes 434 of the two second connecting parts 433, so that one energy absorbing spring 30 is connected between the two first connecting parts 432, and the other energy absorbing spring 30 is connected between the two second connecting parts 433. The connection is stable and reliable, and the assembly is convenient and quick.

[0045] In an embodiment of the present invention, the mounting frame 10 includes a mounting plate 11, a mounting ear 12 and a mounting shaft 13. The mounting plate 11 is used to connect to the target protective object, the mounting ear 12 is provided on the mounting plate 11, and the mounting shaft 13 is provided on the mounting ear 12 and passes through the first connecting rod 41 of the two connecting rod assemblies 40; the connecting frame 20 includes a connecting plate 21, a connecting ear 22 and a connecting shaft 23. The connecting plate 21 is used to connect to the explosion-proof protection structure, the connecting ear 22 is provided on the connecting plate 21, and the connecting shaft 23 is provided on the connecting ear 22 and passes through the second connecting rod 42 of the two connecting rod assemblies 40. The connecting ear 22 is used to abut against the mounting ear 12 when the connecting rod assembly 40 is folded.

[0046] like Figures 1 to 4As shown, one side of the mounting plate 11 is used to connect with the target protective object, and a first hinge point 14 is provided on the side of the mounting plate 11 facing away from the target protective object, and a mounting ear 12 is provided on the first hinge point 14, and a mounting groove is provided on the mounting ear 12, and the mounting groove is used for two first connecting rods 41 to extend into, and the mounting shaft 13 passes through the mounting ear 12 and the two first connecting rods 41, so that the two first connecting rods 41 are coaxially hinged to the mounting ear 12 through the mounting shaft 13; one side of the connecting plate 21 is used to connect with the anti-explosion protective structure, and a second hinge point 24 is provided on the side of the connecting plate 21 facing away from the anti-explosion protective structure, and the second hinge point 24 is provided on the first hinge point 14. A connecting ear 22 is provided on the second hinge point 24, and a connecting groove is opened on the connecting ear 22. The connecting groove is used for two second connecting rods 42 to extend into. The connecting shaft 23 passes through the connecting ear 22 and the two second connecting rods 42, so that the two second connecting rods 42 are coaxially hinged to the connecting ear 22 through the connecting shaft 23, thereby enhancing the linkage between the two connecting rod assemblies 40, improving the folding smoothness and energy absorption reliability, and the contact area between the mounting plate 11 and the target protection object, and between the connecting plate 21 and the explosion-proof protection structure is large, further improving the ability to absorb shock waves and enhancing the connection stability.

[0047] Furthermore, when the explosion-proof protection structure is subjected to the impact of an explosion, the second connecting rod 42 folds toward the first connecting rod 41 to reduce the impact force of the explosion-proof protection structure, and the two third hinge points 44 are away from each other to avoid folding interference. The energy-absorbing spring 30 is stretched, so that the elastic restoring force of the energy-absorbing spring 30 acts on the first connecting rod 41, the second connecting rod 42 and the explosion-proof protection structure to perform local resonance. Both the energy-absorbing spring 30 and the explosion-proof protection structure can absorb the impact energy, suppress the transmission of the explosion shock wave, and improve the vibration isolation protection effect. Moreover, when the explosion-proof protective structure is subjected to a large impact load, the stretching of the energy-absorbing spring 30 reaches a peak value. After the stretching of the energy-absorbing spring 30 exceeds the critical value, the second connecting rod 42 and the first connecting rod 41 complete folding, and the connecting ear 22 is pressed against the mounting ear 12 to achieve self-locking, that is, the elastic restoring force of the energy-absorbing spring 30 cannot drive the second connecting rod 42 to reset. At this time, the impact energy is transmitted to the energy-absorbing spring 30 and converted from kinetic energy into the internal energy of the energy-absorbing spring 30, so that the energy-absorbing spring 30 further absorbs the impact energy, and the second connecting rod 42 and the first connecting rod 41 are in a folded self-locking state, which limits the movement of the explosion-proof protective structure and further improves the explosion-proof stability and reliability.

[0048] In the embodiment of the present invention, the second connecting rod 42 is arc-shaped and protrudes toward the side away from the mounting bracket 10. Figures 1 to 4As shown, the second connecting rod 42 is arranged in an arc shape, and the second connecting rod 42 is protruded in the direction away from the mounting plate 11. The arc-shaped second connecting rod 42 is easier to fold than a straight rod, which improves the smoothness of the folding switching, and the second connecting rod 42 arranged outward can also play a role in guiding the folding, further improving the stability of the structure and the reliability of buffering and vibration reduction.

[0049] In the embodiment of the present invention, the thickness of the first connecting rod 41 is 10 mm to 25 mm, and the thickness of the second connecting rod 42 is 10 mm to 25 mm. Specifically, the thickness of the first connecting rod 41 and the second connecting rod 42 is greater than 10 mm to ensure the structural strength to play a role in buffering and reducing vibration. The thickness of the first connecting rod 41 and the second connecting rod 42 is preferably 20 mm, which has the advantages of good buffering and reducing vibration, easy assembly, and reasonable structural design.

[0050] In addition, the present invention also provides an explosion-proof device, which includes an explosion-proof protection structure and the energy-absorbing connecting seat described above. Specifically, the explosion-proof protection structure is connected to the connecting frame 20, and the mounting frame 10 is connected to the target protective object so that the explosion-proof protection structure is connected to the target protective object through the energy-absorbing connecting seat. The explosion-proof protection structure is used to resist the impact of the explosion. The connecting rod assembly 40 of the energy-absorbing connecting seat can be folded when the explosion-proof protection structure is subjected to the impact of the explosion to play a role in buffering and vibration reduction. The energy-absorbing spring 30 can absorb the impact energy of the explosion and prevent the shock wave and vibration from being transmitted to the target protective object to damage the target protective object, thereby improving the explosion-proof stability and reliability. The specific structure of the energy-absorbing connecting seat refers to the above-mentioned embodiment. Since the explosion-proof device adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
