[0021] Example: As attached Figure 1 To Attachment Fig.17 As shown: a vehicle body inspection and isolation device, including a transmission mechanism 1, a folding frame 2, the transmission mechanism 1 includes a threaded rod 101, a sleeve 103 fixedly installed at the bottom of the threaded rod 101, and a thread sleeve assembly 102 threadedly sleeved on the outside of the threaded rod 101, the outside of the thread sleeve assembly 102 is installed with a folding frame 2 through an axle bolt, and the folding frame 2 is a closed rectangular frame composed of two groups of first folding frames 201 and two groups of second folding frames 202. The two groups of first folding frames 201 form the length of the rectangular frame, the two groups of second folding frames 202 form the width of the rectangular frame, and the first folding frames 201 form the width of the rectangular frame. 01 is composed of a plurality of first connecting rods cross-connected, and the second folding frame 202 is composed of a plurality of second connecting rods cross-connected. The three corners of the rectangular frame are connected to the first folding frame 201 and the second folding frame 202 by connecting corner pieces 203. One corner of the rectangular frame is connected to the first folding frame 201 and the second folding frame 202 by installing a shaft sleeve 206. One side of the two groups of first folding frames 201 is installed with a V-shaped slide frame 204 through a threaded fastener. The length of the first connecting rod is greater than that of the second connecting rod. The interior of the V-shaped slide frame 204 is installed with a protective shed 7 through a slide groove. It also includes a driving mechanism 3 installed at the bottom of the transmission mechanism 1 and used to drive the transmission mechanism 1, the positioning mechanism 4, and the lifting mechanism 5 to drive synchronously; The positioning mechanism 4 is installed on one side of the bottom of the driving mechanism 3, a lifting mechanism 5 is fixedly installed on the bottom of one side of the positioning mechanism 4, and a mounting mechanism 6 is fixedly installed on the bottom end of the lifting mechanism 5; Through the layout of the two first folding frames 201 and the two second folding frames 202, the two first folding frames 201 and the two second folding frames 202 can be synchronously unfolded through the threaded rod 101, so that the unfolded two first folding frames 201 and the two second folding frames 202 form a protective isolation range, such as Figure 3 As shown; First, the driving mechanism 3 synchronously drives the threaded rod 101 to rotate, the positioning mechanism 4 to unfold and position, and the lifting mechanism 5 to operate and lift. The thread sleeve assembly 102 is threadedly connected to the threaded rod 101. The threaded rod 101 serves as an active part and transmits power to the thread sleeve assembly 102 through rotational motion, so that the thread sleeve assembly 102 produces linear displacement. The linearly displaced thread sleeve assembly 102 drives 201 and one end of the second folding frame 202 to move linearly, so that the first folding frame 201 and the second folding frame 202 are folded and moved. The folded first folding frame 201 and the second folding frame 202 drive the other 201 and the second folding frame 202 to expand and move synchronously, so that the protection isolation range of the folding frame 2 can be adjusted according to the range of vehicle body protection, so that the folding frame 2 is suitable for vehicle body maintenance of different specifications. The expanded folding frame 2 is protected on the periphery of the vehicle body to ensure the effective isolation of the maintenance area from other areas, and prevent non-maintenance personnel from entering the maintenance area to cause interference or danger; Secondly, the deployed positioning mechanism 4 extends to the ground and is firmly connected to the ground. Since the entire device is installed on the vehicle body through the mounting mechanism 6, the positioning mechanism 4 can limit the position of the vehicle body to prevent the vehicle being repaired from being accidentally moved, and can also prevent other vehicles from colliding with the vehicle being repaired, so that maintenance personnel can work in a safer and more controllable environment; Finally, the lifting mechanism 5 drives the folding frame 2 to be lifted and lowered, so that the installation mechanism 6 can be adjusted according to the height of the installation position on the vehicle body, so that the device can be installed at different heights on the vehicle body, and the folding frame 2 is ensured to be at a reasonable height, thereby ensuring the protective isolation effect of the folding frame 2; like Figure 7 As shown, the driving mechanism 3 is composed of a mounting seat 301 and a bevel gear assembly 302, and the bevel gear assembly 302 has three meshing bevel gears, and the three bevel gears are distributed in the upper, lower and left directions, wherein the bevel gears distributed in the upper and lower directions are distributed on the same central axis, and the opposite bevel gears are on the central axis, and a transmission rod 303 extending from the inside of the mounting seat 301 is fixedly installed on the top of the bevel gear distributed in the upper direction, and a bevel gear rod 304 extending from the inside of the mounting seat 301 is fixedly installed on the bottom of the bevel gear distributed in the lower direction, and a rotating handle 305 is fixedly installed on one side of the bevel gear distributed in the left direction; Among them, the three bevel gears have the same specifications. The left distributed bevel gear is driven to rotate by holding the rotating handle 305. The rotating left distributed bevel gear drives the upper and lower distributed bevel gears to rotate in the opposite direction. The rotating upper distributed bevel gear drives the threaded rod 101 to rotate through the transmission rod 303 and the sleeve 103. The rotating lower distribution bevel gear drives the linkage bevel gear 407 to rotate through the bevel gear rod 304, and the rotating linkage bevel gear 407 drives the bottom meshing transmission bevel gear 507 to rotate.

[0022] like Figure 8-10 As shown, the positioning mechanism 4 includes a mounting ring 401 fixedly mounted on the bottom of the mounting seat 301, a sleeve frame is fixedly mounted on one side of the top of the mounting ring 401, and the top of the sleeve frame is fixed to the bottom of the mounting seat 301; A gear ring 402 is rotatably mounted on the bottom of the mounting ring 401, a mounting frame 403 is equidistantly mounted on the outside of the mounting ring 401, a gear member 404 is rotatably mounted on the inside of the mounting frame 403, and the gear member 404 is meshed with the gear ring 402, a folding shaft frame 405 is mounted on one side of the gear member 404 through a shaft rod, and a positioning box 406 is mounted on one end of the folding shaft frame 405 through a shaft bolt, and a linkage bevel gear 407 that penetrates to one side of the mounting frame 403 is fixedly mounted on one end of one of the gear members 404 through a shaft rod, and the linkage bevel gear 407 is meshed with the bevel gear rod 304; Among them, the interior of the positioning box 406 is a hollow storage space, which is convenient for storing tools used for repairing the vehicle body, and convenient for maintenance personnel to take tools, which increases the convenience of using the device; The gear parts 404 are equidistantly distributed at the bottom of the gear ring 402 and are meshed and connected. One of the gear parts 404 is fixedly connected to the linked bevel gear 407 through a shaft rod. The rotating linked bevel gear 407 drives the gear part 404 to rotate through the shaft rod. The rotating gear part 404 drives the meshed gear ring 402 to rotate. The rotating gear ring 402 drives the other three meshed gear parts 404 to rotate, so that the four gear parts 404 rotate synchronously in the same direction. The gear parts 404 rotating in the same direction drive the folding shaft frame 405 to unfold through the shaft rod. The unfolded folding shaft frame 405 drives the positioning box 406 to move downward to the ground. The positioning box 406 moved down to the ground is firmly connected to the ground, and the positioning mechanism 4 is fixedly installed on the vehicle body, thereby realizing the positioning of the vehicle body, ensuring the stability of the vehicle body during the inspection and maintenance process.

[0023] like Fig.11 As shown, the lifting mechanism 5 includes a mounting rod 506 fixedly mounted on the bottom of the mounting frame 403, an inner screw rod 501 is rotatably mounted inside the mounting rod 506, an inner toothed collar 502 is threadedly sleeved on the outer side of the inner screw rod 501, and a first extension rod 504 is movably sleeved on the outer side of the inner toothed collar 502; An external threaded sleeve rod 503 is rotatably mounted at the bottom of the internal gear sleeve ring 502, a second extension rod 505 is threadedly sleeved on the outer side of the external threaded sleeve rod 503, and the first extension rod 504 is movably sleeved on the outer side of the second extension rod 505; A transmission bevel gear 507 penetrating the mounting frame 403 is installed at the top of the inner screw rod 501 through a shaft, and the transmission bevel gear 507 is meshed with the linkage bevel gear 407; The inner wall of the external threaded sleeve 503 is fixed with a clamping strip, and both sides of the inner screw 501 are provided with clamping grooves corresponding to the clamping strip. Therefore, the external threaded sleeve 503 is sleeved on the outer side of the inner screw 501 through the clamping strip and the clamping groove, and when the inner screw 501 rotates, the external threaded sleeve 503 is driven to rotate synchronously. The rotating transmission bevel gear 507 drives the inner screw rod 501 to rotate, and the rotating inner screw rod 501 drives the outer threaded sleeve rod 503 and the first extension rod 504 to move downward synchronously through the inner gear ring 502 to achieve primary extension, and the outer threaded sleeve rod 503 rotates synchronously with the inner screw rod 501 through the cooperation of the clamping strip and the clamping slot, and the rotating outer threaded sleeve rod 503 drives the threaded second extension rod 505 to move downward, thereby achieving secondary extension, and the folding frame 2 is driven to be raised and lowered through the secondary extension.

[0024] like Figure 5 , Figure 6 As shown, the thread sleeve assembly 102 includes a thread sleeve 1022 threadedly sleeved on the outside of the threaded rod 101, a connecting sleeve 1021 is sleeved on the outside of the thread sleeve 1022, a locking ring 1023 is rotatably mounted on the bottom of the connecting sleeve 1021, and the inner wall of the locking ring 1023 is threadedly connected to the outer wall of the thread sleeve 1022; Among them, the wire set 1022 is inserted into the inside of the connecting sleeve 1021, and the rotating locking ring 1023 is threadedly connected to the outer wall of the wire set 1022, so as to lock the position of the wire set 1022, and the connecting sleeve 1021 is connected to the first folding frame 201 and one end of the second folding frame 202 through the shaft. Therefore, when the threaded rod 101 rotates, the threads of the threaded rod 101 and the wire set 1022 are engaged with each other. Due to the bevel effect of the thread, the threaded rod 101 will generate a thrust along the axial direction of the thread on the wire set 1022 during the rotation process. This thrust makes the wire set 1022 move linearly in the opposite direction of the rotation of the threaded hole, thereby realizing the linear movement of the wire set 1022. The linearly moving wire set 1022 drives the first folding frame 201 and the second folding frame 202 to fold and move through the connecting sleeve 1021.

[0025] The mounting sleeve 206 is fixedly sleeved on the outer side of the sleeve frame on the top of the mounting ring 401; A reflective plate 205 is installed on one side of the two sets of second folding frames 202 through threaded fasteners; Among them, the mounting sleeve 206 is located below the silk sleeve assembly 102 and is located on the same axis as the central axis. The mounting sleeve 206 is used to fix one end of the first folding frame 201 and the second folding frame 202, so that when the silk sleeve assembly 102 moves, the fixed mounting sleeve 206 drives the first folding frame 201 and the second folding frame 202 to fold and move, and the reflective plate 205 has a reflective effect, thereby increasing the warning effect of the device.

[0026] like Figure 5 , Figure 6 , Figure 7 As shown, a sleeve 103 is fixedly installed at the bottom of the threaded rod 101, and the sleeve 103 is sleeved on the outside of the transmission rod 303; The sleeve 103 is connected to the transmission rod 303 by clamping, so it is convenient to disassemble the threaded rod 101 and to quickly disassemble and assemble the device.

[0027] like Figure 12-Figure 15 As shown, the protective shed 7 includes two brackets 701 and a shed cover 702, and the two brackets 701 are respectively fixed on both sides of the shed cover 702; The bracket 701 includes a support rod 7011, a folding slot 7012, a telescopic rod 7013, and a slide 7014. The two support rods 7011 are movably mounted at both ends of the telescopic rod 7013, and the support rods 7011 are provided with a folding slot 7012 inside. The slide 7014 is movably mounted inside the folding slot 7012, and one end of the support rod 7011 is mounted inside the V-shaped slide frame 204 through the slide 7014. Among them, when the protective shed 7 is unfolded, the two brackets 701 are connected at right angles to unfold and tighten the two sides of the shed cover 702, and when the protective shed 7 is folded, one group of brackets 701 is flipped to be horizontal with the other group of brackets 701, so that the shed cover 702 is folded, and then the two groups of brackets 701 are folded following the folding frame 2, the telescopic rod 7013 is longitudinally contracted, and the two groups of support rods 7011 use the folding groove 7012 and the slide 7014 to extend and retract laterally through the through hole inside the V-shaped slide frame 204.

[0028] like Figure 15-16 As shown, a screw is fixedly installed on the inner side of the V-shaped slide frame 204, and a fastening screw sleeve is sleeved on the outer side of the screw, and two through holes are opened on one side of the V-shaped slide frame 204; Before folding the protective scaffold 7, the screw is unlocked by rotating the fastening screw sleeve, thereby rotating the V-shaped slide frame 204 45 degrees in the opposite direction, so that a set of brackets 701 are rotated to a horizontal state, which facilitates the subsequent folding of the protective scaffold 7.

[0029] like Figure 8As shown, the mounting mechanism 6 includes an extension frame 602 fixedly mounted at the bottom of the lifting mechanism 5, a mounting sleeve 601 is movably sleeved on the outer side of the extension frame 602, a threaded bolt 603 is threadedly connected to one side of the mounting sleeve 601, one end of the threaded bolt 603 is used to limit the extension frame 602, and a clamping frame 604 is clamped and mounted on one side of the bottom of the mounting sleeve 601; Among them, the installation sleeve 601 is fixed on the vehicle body through the clamping frame 604, and the extension frame 602 is stretched to adjust the extension length.
