[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Combined with the provided damper, spring, push rod and slider structures, it is convenient to effectively buffer and reduce shock for the box during subsequent use, thereby preventing the box from shaking and causing noise during subsequent work, improving the practicality of the entire device itself. When the box shakes longitudinally, it will squeeze the first damper fixedly connected to its bottom. At the same time, the connecting seat pushes the moving seat through the push rod, and the moving seat drives the slider to squeeze the first spring. At the same time, under the action of the linkage rod, the extrusion block will squeeze the second damper and the second spring. The reverse force generated by the combination of multiple dampers and spring deformation can achieve the purpose of buffering and shock absorption, thereby improving the stability of the box itself and achieving the purpose of noise reduction.

[0017] 2.

The overall structure is more flexible. When the mounting base is fixedly installed in the mounting groove opened on the side wall of the box, the clamping block will be engaged with the inner side of the clamping groove. At the same time, the reverse force generated by the deformation of the third spring will push the locking rod laterally, and then input one end of the locking rod into the inner side of the lock hole, thereby realizing a quick connection between the mounting base and the box, and facilitating subsequent replacement, which is convenient and fast.

[0018] 3. Combined with the provided rotating seat, cross slot, cross block and fastening bolts and other structures, the installation sleeve can be replaced, which is convenient for subsequent replacement according to actual installation requirements. Compared with the existing installation through a single cross bar, it is more convenient and flexible, and has a wider range of applications. When the cross block is engaged with the inner side of the cross slot, the fastening bolt passes through the through hole opened on the side wall of the rotating seat and extends to the inner side of the bolt slot, thereby realizing a quick connection between the installation sleeve and the rotating seat, and a rotating connection is formed between the rotating seat and the mounting base plate, and the angle of the installation sleeve can be adjusted according to actual installation requirements.

[0030] When in use, the mounting plate 18 is fixed to the side wall of the box body 1, and then the fuel tank cover 25 is installed on the top of the box body 1 to achieve the sealing of the box body 1. When the entire box body 1 shakes during use, the multiple dampers and springs provided can serve as a buffer, thereby achieving the effect of noise reduction.

[0031] As a further implementation of this embodiment, Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, a mounting base 2 is distributed under the box body 1, and a first damper 3 is fixedly installed on one side of the top of the mounting base 2. A plurality of slots are equidistantly provided on the upper surfaces of both ends of the mounting base 2 for the purpose of simple water drainage. A connecting seat 4 is fixedly installed on one side of the bottom of the box body 1, and a push rod 5 is connected to the inner side of the bottom of the connecting seat 4. The two ends of the push rod 5 are respectively connected to the connecting seat 4 and the moving seat 6 to form a rotation connection, and the push rod 5 is symmetrically distributed along the vertical center line of the mounting base 2. The other end of the push rod 5 is connected to the moving seat 6, and the moving seat 6 is connected to the connecting seat 4. A slider 7 is fixedly installed at the bottom of the moving seat 6. A sliding connection is formed between the slider 7 and the cross bar 8. The cross bar 8 passes through the slider 7 and is vertically connected to the inner wall of the mounting base 2. The inner side of the slider 7 is penetrated by the cross bar 8, and the outer surface of the cross bar 8 is sleeved with a first spring 9. The side wall of the slider 7 is connected to a linkage rod 10, and an extrusion block 11 is provided in the middle section of the linkage rod 10. A second damper 12 is distributed on one side of the extrusion block 11, and a second spring 13 is sleeved on the outer surface of the second damper 12. The side wall of the box body 1 is provided with a snap-fit ​​structure;

[0032] When the box body 1 shakes longitudinally during use, the box body 1 will squeeze the first dampers 3 symmetrically arranged on both sides of its bottom and cause them to deform. At the same time, the box body 1 will make the connecting seat 4 fixed at the bottom push the push rod 5 connected to the inner side of its bottom, and then the moving seat 6 will also move laterally under the action of the push rod 5. When the moving seat 6 moves laterally, it will drive the slider 7 fixed at the bottom, and when the slider 7 moves, it will slide along the cross bar 8. At the same time, the slider 7 will squeeze the first spring 9 fixed on one side and realize the first spring 9 deformation, and at the same time, the lateral movement of the slider 7 drives the linkage rod 10 to move synchronously, and then the linkage rod 10 drives the extrusion block 11 to squeeze the second damper 12, thereby realizing the deformation of the second damper 12. When the second damper 12 is deformed, the second spring 13 will also be deformed to generate a reverse force, and then the reverse force generated by the deformation of the first damper 3, the second damper 12 and the two springs can achieve the purpose of buffering and shock absorption, thereby effectively preventing the box body 1 from shaking during practical use, thereby achieving the purpose of noise reduction;

[0033] As a further implementation of this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, the locking structure includes a mounting groove 14, a card slot 15, a lock hole 16 and a protrusion 17. The mounting groove 14 is opened on the side wall of the box body 1, and one side of the mounting groove 14 is connected with the card slot 15. The card slots 15 are symmetrically distributed on both sides of the box body 1, and the inner diameter of the card slot 15 is adapted to the outer diameter of the card block 20. A lock hole 16 is opened on one end surface of the box body 1, and a protrusion 17 is provided on the inner side of the mounting groove 14. A mounting plate 18 is distributed on one side of the box body 1, and a fin 19 is provided on the side of the mounting plate 18 away from the box body 1. The internal structure of the mounting plate 18 is made of heat-conducting material, which can achieve the purpose of heat conduction. A clamping block 20 is fixedly mounted on one end surface of the mounting plate 18, and a third spring 21 is fixedly connected to the inner side of the clamping block 20. The other end of the third spring 21 is fixedly connected to a locking rod 22, and an auxiliary slide 23 is sleeved on the outer side of one end of the locking rod 22. The locking rod 22 is slidably connected to the clamping block 20 through the third spring 21, and the locking rods 22 are symmetrically distributed along the vertical center line of the mounting plate 18. A groove 24 is provided on the side of the mounting plate 18 close to the box body 1. A fuel tank cover 25 is distributed above the box body 1, and a sealing seat 26 is provided at the bottom of the fuel tank cover 25. A first positioning bolt 27 passes through the corner of the fuel tank cover 25.

[0034] When it is necessary to achieve quick installation between the mounting plate 18 and the box body 1, the mounting plate 18 is engaged with the inner side of the mounting groove 14. When the mounting plate 18 is fully engaged with the inner side of the mounting groove 14, the protrusions 17 are respectively input into the inner sides of the multiple grooves 24, thereby providing a guiding effect for the engagement of the mounting plate 18 with the mounting groove 14. At the same time, the protrusions 17 symmetrically distributed along the vertical center line of the mounting plate 18 are engaged with the inner side of the card groove 15. When the protrusions 17 are fully engaged, the lateral force applied to the locking rod 22 disappears. At this time, the reverse force generated by the deformation of the third spring 21 pushes the locking rod 22 in the reverse direction, thereby inputting one end of the locking rod 22 into the inner side of the lock hole 16. The auxiliary slide 23 is also driven by the locking rod 22 to move laterally, thereby achieving a quick installation between the mounting plate 18 and the box body 1, and is also easy to disassemble laterally, which is convenient and quick. At the same time, when the locking rod 22 moves laterally, the auxiliary slide 23 is also driven to move laterally, and the auxiliary slide 23 is used to improve the stability of the locking rod 22 during the lateral movement. When the mounting plates 18 on both sides are installed, the fins 19 provided can play a heat dissipation effect. When the fuel tank cover 25 is engaged with the top of the box body 1, the sealing seat 26 is engaged with the top opening of the box body 1, thereby improving the sealing effect between the two. Subsequently, the first positioning bolt 27 is used to achieve a stable connection between the fuel tank cover 25 and the box body 1.

[0035] As a further implementation of this embodiment, Figure 1 、 Figure 5 and Figure 7 As shown, a rotating seat 28 is fixedly installed at the bottom corner of the mounting base 2, and a cross slot 29 is provided at the bottom of the rotating seat 28. The rotating seat 28 and the box body 1 are rotatably connected, and through holes 30 are equidistantly distributed along the center point of the rotating seat 28. Through holes 30 are provided on the outer surface of the rotating seat 28, and fastening bolts 31 pass through the inner sides of the through holes 30. A cross block 32 is distributed below the rotating seat 28, and a bolt slot 33 is provided on the inner side of the cross block 32. A mounting sleeve 34 is provided at the bottom of the cross block 32, and a second positioning bolt 35 passes through the bottom of the mounting sleeve 34.

[0036] When the bolt 31 is tightened, the bolt 31 is passed through the inner side of the through hole 30 and extended into the bolt groove 33 on the side wall of the cross groove 29. Then, the bolt 31 is tightened to achieve a quick connection between the cross block 32 and the rotating seat 28. It is easy to disassemble and replace the mounting sleeve 34 according to the actual installation requirements. When the mounting sleeve 34 is locked with the reserved structure, the second positioning bolt 35 is passed through the bottom of the mounting sleeve 34 and matched with the nut to achieve the sealing treatment of the mounting sleeve 34. In this way, the mounting of the box body 1 is achieved. Since the rotating seat 28 and the mounting base 2 are rotatably connected, the direction of the mounting sleeve 34 can be adjusted according to the actual installation requirements, which is convenient for the subsequent better installation of the entire structure and has higher overall practicality.

[0037] Specific working principle:

[0038] When in use, first engage the mounting plate 18 with the inner side of the mounting groove 14. When the mounting plate 18 is fully engaged with the inner side of the mounting groove 14, the protrusions 17 will be respectively input into the inner sides of the multiple grooves 24, thereby providing a guiding effect for the engagement of the mounting plate 18 with the mounting groove 14. At the same time, the protrusions 17 symmetrically distributed along the vertical center line of the mounting plate 18 will be engaged with the inner side of the card groove 15. When the protrusions 17 are fully engaged, the lateral force applied to the locking rod 22 disappears. At this time, the reverse force generated by the deformation of the third spring 21 will push the locking rod 22 in the reverse direction, thereby inputting one end of the locking rod 22 into the inner side of the lock hole 16, thereby realizing rapid installation between the mounting plate 18 and the box body 1, and also facilitating subsequent disassembly, which is convenient and fast. The auxiliary slide plate 23 is also moved laterally when the locking rod 22 moves laterally, and the auxiliary slide plate 23 is used to improve the stability of the locking rod 22 during the lateral movement. When the mounting plates 18 on both sides are installed, the fins 19 provided can achieve the effect of heat dissipation. When the fuel tank cover 25 is engaged with the top of the box body 1, the sealing seat 26 is engaged with the top opening of the box body 1, thereby improving the sealing effect between the two. Subsequently, the first positioning bolt 27 is used to achieve a stable connection between the fuel tank cover 25 and the box body 1. When it is necessary to install the entire box body 1 and the reserved structure, the cross block 32 is first engaged with the inner side of the cross groove 29 opened at the bottom of the rotating seat 28. When 32 is fully engaged with the cross groove 29, the fastening bolt 31 is passed through the inner side of the through hole 30 and extended into the bolt groove 33 opened on the side wall of the cross groove 29. Then the fastening bolt 31 is screwed to achieve a quick connection between the cross block 32 and the rotating seat 28, and it is easy to disassemble later, so that the installation sleeve 34 can be replaced according to actual installation requirements. When the installation sleeve 34 is engaged with the reserved structure, the second positioning bolt 35 is passed through the bottom of the installation sleeve 34, and the matching nut is used to achieve the sealing treatment of the installation sleeve 34, thereby realizing the installation of the box body 1. Since the rotating seat 28 and the mounting base 2 form a rotating connection, the installation sleeve can be adjusted according to actual installation requirements. The orientation of 34 is convenient for the subsequent better installation of the entire structure, and the overall practicality is higher. When the box body 1 shakes longitudinally during use, the box body 1 will squeeze the first dampers 3 symmetrically arranged on both sides of its bottom and cause it to deform accordingly. At the same time, the box body 1 will make the connecting seat 4 fixed at the bottom push the push rod 5 connected to the inner side of its bottom for rotation. Then, under the action of the push rod 5, the moving seat 6 will also move laterally. When the moving seat 6 moves laterally, it will drive the slider 7 fixed at the bottom. When the slider 7 moves, it will slide along the cross bar 8. At the same time, the slider 7 will squeeze the first spring 9 fixed to one side and realize the deformation of the first spring 9. At the same time, the lateral movement of the slider 7 will drive the linkage rod 10 to move synchronously.The linkage rod 10 then drives the extrusion block 11 to squeeze the second damper 12, thereby deforming the second damper 12. When the second damper 12 deforms, the second spring 13 also deforms and generates a reverse force. The reverse force generated by the deformation of the first damper 3, the second damper 12, and the two springs can achieve the purpose of buffering and shock absorption, thereby effectively preventing the box body 1 from shaking during practical use, thereby achieving the purpose of noise reduction.
