Description

Technical Field

[0001] This utility model relates to the field of gantry washing and disinfection rack technology, and in particular to a device for fixing a base on a hard road surface. Background Technology

[0002] A gantry decontamination rack is a specialized piece of equipment used for decontamination operations. It is typically installed at vehicle entrances and exits to thoroughly clean and disinfect vehicles entering and exiting. Its main functions include removing contaminants from vehicle surfaces, disinfection, and preventing the spread of viruses and bacteria. The Type 03 spray truck is primarily used for spraying pesticides and chemicals, while the Type 04 spray truck has functions such as firefighting, rescue, decontamination, and water supply. Both Type 03 and Type 04 spray trucks typically require a gantry decontamination rack for vehicle decontamination after operations.

[0003] Traditionally, the rapid installation of gantry-type decontamination racks involves driving nails into the soil and then securing the rack with ropes to ensure stability. However, this method is only suitable for dirt surfaces. On hard surfaces such as cement or asphalt, nails cannot be driven in effectively, hindering stable installation. Therefore, ensuring stable installation of gantry-type decontamination racks on hard surfaces is a crucial issue that needs to be addressed in the design of fixed base devices for hard surfaces. Summary of the Invention

[0004] This invention addresses the problem that gantry washing and disinfection racks cannot be stably installed on hard surfaces by providing a fixed base device for hard road surfaces.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a fixed base device for hard road surfaces, including a gantry decontamination rack, wherein a support base is fixedly connected to the bottom side wall of the gantry decontamination rack, and further includes:

[0007] A fixed base structure is provided on both sides of the gantry washing and disinfection rack;

[0008] A support structure is provided on both sides of the gantry washing and disinfection rack, and the support structure supports the gantry washing and disinfection rack.

[0009] A snap-fit ​​fixing structure is provided on the fixed base structure and the support structure.

[0010] Preferably, connecting blocks two are fixedly connected to the side walls on both sides of the support base, and a snap-fit ​​groove three is provided on the top side wall of the connecting blocks two. Two fixing rings are fixedly connected to the side walls of the vertical rods on both sides of the gantry washing and disinfection rack, and connecting blocks one are fixedly connected to the side walls of the two fixing rings. A snap-fit ​​groove one is provided on the top side wall of the connecting blocks one. A wind direction and anemometer is fixedly connected to the top of the vertical rods on both sides of the gantry washing and disinfection rack.

[0011] Preferably, the fixed base structure includes a first fixed base plate, a second fixed base plate, a second fixed housing, a rotating connecting block, a threaded sleeve, a first threaded rod, a rotating gear, and a transmission gear. The second fixed housing is fixedly connected to the side wall of the first fixed base plate. The transmission gear and the rotating connecting block are rotatably connected to the side wall of the first fixed base plate. The threaded sleeve is fixedly connected to the end of the rotating connecting block. The first threaded rod is threadedly connected to the inside of the threaded sleeve. The first threaded rod is fixedly connected to the side wall of the second fixed base plate. The rotating gear is fixedly connected to the side wall of the threaded sleeve. The rotating gear is located on both sides of the transmission gear, and the rotating gear and the transmission gear mesh with each other.

[0012] In this technical solution, rotating the threaded sleeve causes the rotating gear to rotate, which in turn drives the rotating gear on the other side to rotate via a transmission gear. The rotating gear on the other side then drives the threaded sleeve on the other side to rotate, causing the two threaded sleeves to rotate synchronously. The threaded sleeves rotate and move on the threaded rod, which in turn moves the fixed base plate. This allows for better adjustment of the support range of the fixed base structure as needed, making the gantry washing and disinfection rack more stable.

[0013] Preferably, the fixed base structure includes a fixing nail, a fixing plate, a sliding groove, and a plug-in groove. The fixing nail is fixedly connected to the top side wall of the first fixed base plate, and the fixing plate is fixedly connected to the top side wall of the second fixed base plate. The fixing plate extends out of the end of the second fixed base plate. The first sliding groove is provided on the side wall of the fixing plate, and the first plug-in groove is provided on the side wall of the second fixed base plate near the fixing plate.

[0014] In this technical solution, the second fixed base plate is connected to the second connecting plug, and the second connecting plug is snapped into the first plug groove, so that the second fixed base plate can be fixed on both sides of the support base. This allows the fixed base structure to be quickly connected to both sides of the support base, increasing the support range at the bottom of the gantry washing and disinfection rack, and making the installation of the gantry washing and disinfection rack more stable.

[0015] Preferably, the first insertion slot and the second connecting block cooperate with each other, the width and thickness of the first fixed base plate and the second fixed base plate are consistent with the support base, and a pull rope is sleeved on the side wall of the fixing nail, the end of the pull rope is fixedly connected to the top side wall of the vertical rods on both sides of the gantry washing and disinfection rack.

[0016] In this technical solution, the pull rope can better hold the gantry washing and disinfection frame with the help of the fixed base plate, making the gantry washing and disinfection frame support more stable.

[0017] Preferably, the support structure includes a support base block, a first support rod, a connecting block, a connecting plate, a support block, a nut, a second threaded rod, and a second support rod. Two nuts are threaded onto the second threaded rod, and two support blocks are rotatably connected to the two nuts. The first support rod and the second support rod are respectively fixedly connected to the side walls of the two support blocks. The bottom end of the second support rod is fixedly connected to the support base block. Two connecting plates are rotatably connected to the top two sides of the first support rod, and a connecting block is fixedly connected between the two connecting plates.

[0018] In this technical solution, the first support rod can rotate around the connecting plate to adjust its angle. Rotating the nut on the second threaded rod can move the second support rod, thereby adjusting the length of the entire support structure and allowing the support structure to be adjusted in terms of support angle as needed.

[0019] Preferably, the side wall of the connecting block is provided with a sliding groove and a plug-in groove, and the plug-in groove and the connecting plug-in block cooperate with each other.

[0020] In this technical solution, the connecting block is connected to the connecting plug one, and the connecting plug one is snapped into the plug groove two. When the connecting plug one abuts against the inner side wall of the plug groove two, the snap groove one of the connecting plug one is directly opposite the snap block, and the snap block is snapped into the snap groove one, so that the connecting block and the fixed ring are better fixedly connected, thereby making the support structure quickly connected to both sides of the gantry washing and disinfection rack, and providing auxiliary support for the gantry washing and disinfection rack.

[0021] Preferably, the snap-fit ​​fixing structure includes a snap-fit ​​block, a first spring, a connecting rod, a handle block, and a third sliding groove. The snap-fit ​​block is slidably connected in the first and second sliding grooves respectively. The first spring and the connecting rod are fixedly connected to the top side wall of the snap-fit ​​block. The other end of the first spring is fixedly connected to the inner side wall of the first and second sliding grooves respectively. The other end of the connecting rod extends out of the side wall of the fixing plate and the connecting block respectively and is fixedly connected to the handle block. The third sliding groove is opened in the side wall of the handle block. The snap-fit ​​block, the first snap-fit ​​groove, and the third snap-fit ​​groove cooperate with each other.

[0022] In this technical solution, pulling the handle block upward causes the connecting rod to move upward, which in turn causes the locking block to move upward. Spring 1 is compressed, and the locking block can retract into sliding groove 2. The locking block engages into locking groove 1, which effectively prevents connecting plug 1 from disengaging from locking groove 2. The locking block engages into locking groove 3, which prevents connecting plug 2 from disengaging from locking groove 1.

[0023] Preferably, the snap-fit ​​fixing structure includes a limiting frame, a sliding rod, a pressing plate, and a second spring. The limiting frame is slidably connected in the sliding groove, and the second springs are fixedly connected at equal intervals between the limiting frames. A sliding rod is fixedly connected to the side wall of the limiting frame, and the sliding rod is slidably connected to the side wall of the handle block. The other end of the sliding rod extends out of the side wall of the handle block and is fixedly connected to the pressing plate.

[0024] In this technical solution, when the pressing plate on the connecting block is pinched, the pressing plate drives the limiting frame to move through the sliding rod. The spring is compressed, causing the limiting frame to leave the locking groove and retract into the sliding groove, thus no longer restricting the movement of the handle block.

[0025] Preferably, the snap-fit ​​fixing structure includes a limiting plate and a second snap-fit ​​groove. The limiting plate is fixedly connected to the top side wall of the fixing plate and the connecting block respectively. The second snap-fit ​​groove is provided on the side walls of the opposite sides of the limiting plate. The second snap-fit ​​groove and the end of the limiting frame cooperate with each other.

[0026] In this technical solution, the second spring unfolds and pushes the limiting frame to engage with the second locking groove, and the limiting frame can restrict the upward movement of the handle block.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. By pinching the pressing plate on the connecting block, the limiting frame no longer restricts the movement of the handle block. Pulling the handle block upwards causes the locking block to retract into sliding groove 2 and sliding groove 1. Then, the connecting plug 1 is locked into the plug groove 2, and the connecting plug 2 is locked into the plug groove 1. Releasing the handle block causes the spring 1 to unfold, pushing the locking block into the locking groove 1 and locking groove 3. This restricts the connecting plug 1 and connecting plug 2, making it easier for the support structure and the fixed base structure to be quickly connected to the gantry washing and disinfection rack. While providing auxiliary support on both sides of the gantry washing and disinfection rack, it also increases the support range at the bottom of the gantry washing and disinfection rack, making the gantry washing and disinfection rack more stable when installed on hard surfaces.

[0030] 2. By releasing the handle block, spring one unfolds, pushing the locking block into locking slot one, and spring two unfolds, pushing the limiting frame into locking slot two. The limiting frame restricts the upward movement of the handle block, thereby preventing the locking block from disengaging from locking slot one or locking slot three. This allows the locking block to effectively restrict the connecting plug one from disengaging from plug slot two, and restricts the connecting plug two from disengaging from plug slot one. This makes it easier for the support structure and the fixed base structure to be firmly fixed on the gantry washing and disinfection rack, and less likely to loosen.

[0031] 3. This application allows for the erection of the gantry decontamination rack without compromising its intended use, and it can also be well installed on hard surfaces, thus significantly expanding the application scope of the gantry decontamination rack. Attached Figure Description

[0046] The fixed base structure 4 includes a first fixed base plate 401, a second fixed base plate 402, a second fixed housing 403, a rotating connecting block 404, a threaded sleeve 405, a first threaded rod 406, a rotating gear 407, and a transmission gear 408. The second fixed housing 403 is fixedly connected to the side wall of the first fixed base plate 401. The transmission gear 408 and the rotating connecting block 404 are rotatably connected to the side wall of the first fixed base plate 401. The threaded sleeve 405 is fixedly connected to the end of the rotating connecting block 404. The first threaded rod 406 is internally threaded into the threaded sleeve 405. The first threaded rod 406 is fixedly connected to the side wall of the second fixed base plate 402. The rotating gear 407 is fixedly connected to the side wall of the threaded sleeve 405. The rotating gear 407 is located on both sides of the transmission gear 408, and the rotating gear 407 and the transmission gear 408 mesh with each other.

[0047] Rotating the threaded sleeve 405 causes the rotating gear 407 to rotate. The rotating gear 407, through the transmission gear 408, drives the rotating gear 407 on the other side to rotate. The rotating gear 407 on the other side drives the threaded sleeve 405 on the other side to rotate, so that the two threaded sleeves 405 rotate synchronously. The threaded sleeve 405 rotates and moves on the threaded rod 406, causing the fixed base plate 401 to move. This allows for better adjustment of the support range of the fixed base structure 4 as needed, making the gantry washing and disinfection rack 1 more stable.

[0048] The fixed base structure 4 includes a fixing nail 411, a fixing plate 412, a sliding groove 413, and a plug-in groove 414.

[0049] The second fixed base plate 402 is connected to the second connecting plug 10. The second connecting plug 10 is snapped into the first plug slot 414, so that the second fixed base plate 402 can be fixed on both sides of the support base 2. This allows the fixed base structure 4 to be quickly connected to both sides of the support base 2, increasing the support range at the bottom of the gantry washing and disinfection rack 1 and making the installation of the gantry washing and disinfection rack 1 more stable.

[0050] The first insertion slot 414 and the second connecting block 10 cooperate with each other. The width and thickness of the first fixed base plate 401 and the second fixed base plate 402 are consistent with the support base 2. A pull rope 3 is sleeved on the side wall of the fixing nail 411. The end of the pull rope 3 is fixedly connected to the top side wall of the vertical rods on both sides of the gantry washing and disinfection rack 1.

[0051] The pull rope 3 can better hold the gantry washing and disinfection rack 1 with the help of the fixed base plate 401, making the gantry washing and disinfection rack 1 more stable.

[0052] The support structure 5 includes a support base block 501, a first support rod 502, a connecting block 503, a connecting plate 504, a support block 505, a nut 506, a second threaded rod 507, and a second support rod 508. Two nuts 506 are threadedly connected to the second threaded rod 507. Two support blocks 505 are rotatably connected to the two nuts 506. The first support rod 502 and the second support rod 508 are respectively fixedly connected to the side walls of the two support blocks 505. The bottom end of the second support rod 508 is fixedly connected to the support base block 501. Two connecting plates 504 are rotatably connected to the top two sides of the first support rod 502. A connecting block 503 is fixedly connected between the two connecting plates 504.

[0053] Support rod 502 can rotate around connecting plate 504 to adjust its angle. Rotating nut 506 on threaded rod 507 can move support rod 508, thereby adjusting the length of the entire support structure 5 and allowing the support structure 5 to be adjusted to adjust its support angle as needed.

[0054] The side wall of the connecting block 503 is provided with a sliding groove 511 and a plug-in groove 512, and the plug-in groove 512 and the connecting plug 7 cooperate with each other.

[0055] Connecting block 503 to connecting plug 7, connecting plug 7 snaps into plug groove 512, connecting plug 7 abuts against the inner wall of plug groove 512, the snap groove 8 of connecting plug 7 is directly opposite snap block 901, snap block 901 snaps into snap groove 8, so that connecting block 503 is better fixedly connected to fixing ring 6, thereby better connecting support structure 5 to both sides of gantry washing and disinfection rack 1, providing auxiliary support for gantry washing and disinfection rack 1.

[0056] The snap-fit ​​fixing structure 9 includes a snap-fit ​​block 901, a spring 902, a connecting rod 903, a handle block 904, and a sliding groove 905. The snap-fit ​​block 901 is slidably connected in the sliding groove 413 and the sliding groove 511. The spring 902 and the connecting rod 903 are fixedly connected to the top side wall of the snap-fit ​​block 901. The other end of the spring 902 is fixedly connected to the inner side wall of the sliding groove 413 and the sliding groove 511. The other end of the connecting rod 903 extends out of the side wall of the fixing plate 412 and the connecting block 503 and is fixedly connected to the handle block 904. The sliding groove 905 is opened in the side wall of the handle block 904. The snap-fit ​​block 901, the snap-fit ​​groove 8, and the snap-fit ​​groove 3 11 cooperate with each other.

[0057] Pull the handle block 904 upwards. The handle block 904 drives the connecting rod 903 to move upwards. The connecting rod 903 drives the locking block 901 to move upwards. The spring 902 is compressed, and the locking block 901 can retract into the sliding groove 511.

[0058] The snap-fit ​​block 901 snaps into the snap-fit ​​slot 8, which can effectively prevent the connecting plug 7 from detaching from the connecting slot 2 512. The snap-fit ​​block 901 snaps into the snap-fit ​​slot 3 11, which can prevent the connecting plug 2 10 from detaching from the connecting slot 1 414.

[0059] The snap-fit ​​fixing structure 9 includes a limiting frame 911, a sliding rod 912, a pressing plate 913, and a second spring 914. The limiting frame 911 is slidably connected in the sliding groove 905. The second spring 914 is fixedly connected at equal intervals between the limiting frames 911. The sliding rod 912 is fixedly connected to the side wall of the limiting frame 911. The sliding rod 912 is slidably connected to the side wall of the handle block 904. The other end of the sliding rod 912 extends out of the side wall of the handle block 904 and is fixedly connected to the pressing plate 913.

[0060] When the pressing plate 913 on the connecting block 503 is pinched, the pressing plate 913 drives the limiting frame 911 to move through the sliding rod 912. The second spring 914 is compressed, causing the limiting frame 911 to leave the second snap-fit ​​groove 922 and retract into the third sliding groove 905, no longer restricting the movement of the handle block 904.

[0061] The snap-fit ​​fixing structure 9 includes a limiting plate 921 and a snap-fit ​​groove 922. The limiting plate 921 is fixedly connected to the top side wall of the fixing plate 412 and the connecting block 503 respectively. The snap-fit ​​groove 922 is provided on the side walls of the two opposite sides of the limiting plate 921. The snap-fit ​​groove 922 and the end of the limiting frame 911 cooperate with each other.

[0062] Spring 2 914 unfolds and pushes the limiting frame 911 into the locking slot 2 922, and the limiting frame 911 can restrict the upward movement of the handle block 904.

[0063] When using this utility model, during assembly, pinch the pressing plate 913 on the connecting block 503. The pressing plate 913 drives the limiting frame 911 to move through the sliding rod 912. The second spring 914 is compressed, causing the limiting frame 911 to leave the second locking groove 922 and retract into the third sliding groove 905, no longer restricting the movement of the handle block 904. Pull the handle block 904 upward, and the handle block 904 drives the connecting rod 903 to move upward. The connecting rod 903 drives the locking block 901 to move upward, and the first spring 902 is compressed, causing the locking block 901 to retract into the second sliding groove 511.

[0064] Next, connect the connecting block 503 to the connecting plug 7. The connecting plug 7 is engaged in the insertion slot 2 512. When the connecting plug 7 abuts against the inner wall of the insertion slot 2 512, the engagement slot 8 on the plug 7 is directly opposite the engagement block 901. Release the handle block 904, the spring 1 902 unfolds, and pushes the engagement block 901 to engage in the engagement slot 1 8. The spring 2 914 unfolds and pushes the limiting frame 911 to engage in the engagement slot 2 922. The limiting frame 911 restricts the upward movement of the handle block 904, thereby preventing the engagement block 901 from disengaging from the engagement slot 1 8. This allows the engagement block 901 to better restrict the connecting plug 7 from disengaging from the insertion slot 2 512, so that the connecting block 503 is better fixedly connected to the fixing ring 6. This allows the support structure 5 to be quickly connected to both sides of the gantry washing and disinfection rack 1, providing auxiliary support for the gantry washing and disinfection rack 1.

[0065] The support rod 502 can rotate around the connecting plate 504 to adjust the angle. Rotating the nut 506 on the threaded rod 507 can move the support rod 508, thereby adjusting the length of the entire support structure 5, so that the support structure 5 can be adjusted to adjust the support angle as needed.

[0066] Pinch the handle block 904 and pull upwards, causing the snap-fit ​​block 901 on the fixed plate 412 to retract into the sliding groove 413. Then connect the fixed base plate 402 to the connecting plug 10. The connecting plug 10 snaps into the insertion groove 414. Release the handle block 904, allowing the snap-fit ​​block 901 to snap into the snap-fit ​​groove 11, preventing the connecting plug 10 from detaching from the insertion groove 414. This ensures that the fixed base plate 402 can be better fixed on both sides of the support base 2, facilitating the quick connection of the fixed base structure 4 to both sides of the support base 2 and increasing the support range at the bottom of the gantry washing and disinfection rack 1. This makes the installation of the gantry washing and disinfection rack 1 more stable. Rotating the threaded sleeve 405 causes the rotating gear 407 to rotate. The rotating gear 407 drives the rotating gear 407 on the other side to rotate through the transmission gear 408. The rotating gear 407 on the other side drives the threaded sleeve 405 on the other side to rotate, so that the two threaded sleeves 405 rotate synchronously. The threaded sleeve 405 rotates and moves on the threaded rod 406, which drives the fixed base plate 401 to move. This allows for better adjustment of the support range of the fixed base structure 4 as needed, making the support of the gantry washing and disinfection rack 1 more stable.
