DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6As shown, the utility model provides a foldable transport frame, including a base 1, an inner wall of the base 1 is provided with a support mechanism 2, the support mechanism 2 includes a frame body A201, the inner wall of the base 1 is rotatably connected with two sets of rotating shafts 203, a left outer wall of one set of rotating shafts 203 is fixedly connected with a rotating wheel A204, and a left outer wall of the other set of rotating shafts 203 is fixedly connected with a rotating wheel B206, a traction rope A205 is wound around the outer wall of the rotating wheel A204, and a traction rope A205 is wound around the outer wall of the rotating wheel B206 Traction rope B207, the left inner wall of the base 1 is rotatably connected to a rotating block 208, the outer wall of the rotating block 208 is provided with two sets of slots 209, the left outer wall of the rotating block 208 is fixedly connected to a handle 210, the outer wall of the rotating shaft 203 is fixedly connected to the frame B202, the left outer wall of the base 1 is fixedly connected to a fixed block 211, the inner wall of the fixed block 211 is elastically connected to a wedge block 213 through a spring A212, and the inner wall of the frame B202 is provided with a fixing component.

[0025] The above scheme is adopted: the device can be pushed to transport the glass thereon by means of four sets of universal wheels arranged under the base 1, and the device can be folded to save space by means of the support mechanism 2, and can be unfolded for use conveniently and quickly; when the support mechanism 2 is unfolded, the frame A201, the frame B202 and the base 1 are in a triangular shape, and the glass can be leaned against the frame A201 and the frame B202 and fixed by ropes, and the frame A201 and the frame B202 can be further reinforced by the fixing assembly; when the handle 210 is turned clockwise, the glass can be brought The rotating block 208 rotates synchronously clockwise, generating pulling force on the traction rope A205 and the traction rope B207. Since the traction rope A205 and the traction rope B207 are both fixed on the rotating block 208 at one end and fixed on the rotating wheel A204 and the rotating wheel B206 at the other end, when the rotating block 208 rotates clockwise, the rotating wheel A204 can be pulled to rotate clockwise, while the rotating wheel B206 rotates counterclockwise, which can drive the corresponding two sets of rotating shafts 203 to rotate synchronously, so that the frame A201 and the frame B202 can be flipped upward synchronously, and the glass can be unfolded for transportation.

[0026] like Figure 3 to Figure 4 As shown, the wedge block 213 maintains the arc surface downward without being affected by external forces, and is ejected due to the elastic force of the spring A212, and is engaged with a group of slots 209. When the rotating block 208 rotates, an extrusion force is generated on the arc surface of the wedge block 213, so that the wedge block 213 moves inward along the inner wall of the fixed block 211, and will not affect the rotation of the rotating block 208; when the rotating block 208 rotates until the frame A201 and the frame B202 are both unfolded, and the top positions of the two correspond, as shown in FIG. Figure 2As shown, the wedge block 213 is ejected due to the elastic force of the spring A212 and is engaged with another set of slots 209. The straight surface of the wedge block 213 contacts the inner wall of the slot 209, so that the rotating block 208 cannot rotate counterclockwise, and the position of the frame A201 and the frame B202 can be fixed; the outer wall of the wedge block 213 is provided with a protrusion, which passes through the outer wall of the fixed block 211. The wedge block 213 can be disengaged from the slot 209 by moving the protrusion, so that the rotating block 208 can be rotated counterclockwise and the frame A201 and the frame B202 can be folded.

[0027] like Figures 2 to 4 As shown, the frame A201 is fixedly connected to the outer wall of a group of rotating shafts 203, the rotating wheel A204 and the rotating wheel B206 are both rotatably connected to the left inner wall of the base 1, the outer walls of the frame A201 and the frame B202 are fixedly connected with the rubber strip 3, the traction rope A205 and the traction rope B207 are both wound around the outer wall of the rotating block 208, and the rotating block 208 passes through the left outer wall of the base 1, one end of the spring A212 is fixedly connected to the outer wall of the wedge block 213, and the other end of the spring A212 is fixedly connected to the inner wall of the fixed block 211, the outer wall of the wedge block 213 is slidably connected to the inner wall of the fixed block 211, and the wedge block 213 is engaged with the slot 209.

[0028] By adopting the above scheme: the frame A201 and the frame B202 can be opened by rotating the rotating block 208 clockwise, and the frame A201 and the frame B202 can be folded by rotating the rotating block 208 counterclockwise, so that when not in use, the space occupied by the device can be saved and it is convenient to carry and transport. The rubber strip 3 can prevent the glass from direct contact with the frame A201 and the frame B202, and protect the glass from scratches.

[0029] like Figures 5 and 6 As shown, the fixed component includes two groups of card blocks 402, the two groups of card blocks 402 are elastically connected by a reset spring 401, the top outer wall of the card block 402 is fixedly connected with a shift block 405, the inner wall of the frame B202 is elastically connected with a moving block 407 through a spring B406, the top outer wall of the moving block 407 is fixedly connected with a baffle 403, the outer wall of the frame A201 is provided with a groove 404, the two ends of the reset spring 401 are respectively fixedly connected to the outer walls of the two groups of card blocks 402, the card block 402 is slidably connected to the inner wall of the frame B202, the shift block 405 penetrates the outer wall of the frame B202, one end of the spring B406 is fixedly connected to the outer wall of the moving block 407, the other end of the spring B406 is fixedly connected to the inner wall of the frame B202, and the outer wall of the moving block 407 is slidably connected to the inner wall of the frame B202.

[0030] The above scheme is adopted: the top of the shift block 405 and the baffle 403 are both lower than the top of the frame B202. When the glass is placed on the frame B202, the shift block 405 and the baffle 403 do not contact the glass surface; after the frame A201 and the frame B202 are unfolded, the block 402 is engaged with the groove 404, which can improve the stability of the frame A201 and the frame B202; the baffle 403 is in the shape of a "concave" character. When folding, the baffle 403 can be moved to make the moving block 407 move synchronously and squeeze the spring B406. Then, the shift block 405 is moved to move the two groups of blocks 402 to the middle at the same time, and they are out of contact with the groove 404, and the spring is reset. The spring 401 contracts under the force, and the baffle 403 is released at this time. Due to the elastic force of the spring B406 itself, the moving block 407 and the baffle 403 can be moved and reset at the same time, so that the two groups of shift blocks 405 are stuck in the middle part of the baffle 403 at the same time, and the fixed state of the block 402 is maintained, and the frame A201 and the frame B202 can be flipped down and folded up; after unfolding, the baffle 403 can be pushed to disengage the contact with the two groups of shift blocks 405, and the elastic force of the reset spring 401 makes the two groups of blocks 402 pop out and engage with the corresponding grooves 404, so that reinforcement can be carried out. There is no need to fix it through assembly operation or turning bolts, which is more convenient, quick, time-saving and labor-saving.

[0031] The working principle and use process of this utility model:

[0032] When the device needs to be deployed for use, the handle 210 can be held and rotated clockwise to rotate the rotating block 208, generating tension on the traction rope A205 and the traction rope B207. The traction rope A205 drives the rotating wheel A204 to rotate clockwise, and the traction rope B207 drives the rotating wheel B206 to rotate counterclockwise, so that the corresponding rotating shaft 203 can be rotated synchronously, driving the frame A201 and the frame B202 to flip upward at the same time, and the device can be deployed; during the rotation of the rotating block 208, the wedge block 213 is squeezed to move inward along the inner wall of the fixed block 211, and the spring A212 is forced to shrink. When the rotating block 208 rotates to the top position of the frame A201 and the frame B202 and intersects, a group of slots 209 correspond to the position of the wedge block 213. At this time, the wedge block 213 is ejected due to the elastic force of the spring A212, and the straight surface of the wedge block 213 contacts the inner wall of the slot 209, so that the rotating block 208 will not rotate counterclockwise, thereby fixing the frame A201 and the frame B202.

[0033] After the fixation is completed, the operator can move the baffle 403 so that the baffle 403 and the moving block 407 generate a squeezing force on the spring B406, and the baffle 403 is out of contact with the two sets of shifting blocks 405. The two sets of clamping blocks 402 are ejected to both sides due to the elastic force of the reset spring 401 and are engaged with the groove 404, so that the frame A201 and the frame B202 can be reinforced. At this time, the operator can lean the glass sideways on the frame A201 and the frame B202, and fix the glass with ropes. The rubber strip 3 can prevent the glass from being scratched by direct contact with the frame A201 and the frame B202, and then push the device to be transported through the four sets of universal wheels under the base 1.

[0034] When the device needs to be folded after conveying, the baffle 403 can be moved to force the spring B406 to contract, and the two sets of shifting blocks 405 can be moved inward, so that the block 402 is out of contact with the groove 404, and then the baffle 403 is released. The spring B406 moves the baffle 403 to reset due to its own elastic force. The two sets of shifting blocks 405 are stuck in the middle of the baffle 403. The two sides of the baffle 403 can limit the shifting blocks 405, so that the position of the block 402 can be kept fixed. At this time, the outer wall of the wedge block 213 can be moved The protrusion of the wedge block 213 disengages from the card slot 209, and the rotating block 208 can be rotated counterclockwise, so that the traction rope A205 pulls the rotating wheel A204 to rotate counterclockwise, and the traction rope B207 pulls the rotating wheel B206 to rotate clockwise, so that the frame A201 and the frame B202 can be turned downward and put into the interior of the base 1 to complete the folding. There is no need to assemble and fix the device through an assembled design, nor is there any need to reinforce it by turning the bolts multiple times. It is more convenient, quick and simple to operate.
