[0023] like Figures 1 to 4 As shown, the utility model provides a construction material sales and transportation device, comprising:

[0024] Cart body 1;

[0025] The left and right sides of the cart body 1 are fixedly connected to a fixing box 2. The left side of the inner wall of the fixing box 2 is movably connected to a rotating rod 3 through a bearing seat. The right side of the rotating rod 3 passes through the right side of the fixing box 2 and is fixedly connected to a support leg 4. The bottom of the support leg 4 is in contact with the ground. The surface of the rotating rod 3 and the inside of the fixing box 2 are fixedly sleeved with a locking mechanism 5.

[0026] The locking mechanism 5 includes a rotating wheel 501, an H-shaped fixing rod 502, a connecting plate 503, a rectangular plate 504, a slide plate 505, a block 506, a trapezoidal plate 507, a fixing block 508, a support 509, a threaded turning handle 510 and a triangular block 511. The surface of the rotating rod 3 and the interior of the fixing box 2 are fixedly sleeved with the rotating wheel 501. The left and right sides of the rotating wheel 501 are sleeved on the surface of the rotating rod 3 and fixedly connected with the H-shaped fixing rod 502. The front end and the back end of the inner wall of the fixing box 2 are fixedly connected with the connecting plate 503. The front end and the back end of the inner wall of the fixing box 2 and the inner side of the connecting plate 503 are fixedly connected with the rectangular plate 504, a slide plate 505 is connected to the inner side of the connecting plate 503 and the surface of the rectangular plate 504 for horizontal sliding connection, and the left and right sides of the back end of the slide plate 505 are fixedly connected with a clamping block 506, and the inner side of the rectangular plate 504 and the surface of the rotating rod 3 are fixedly connected with a trapezoidal plate 507, and the center of the front end of the slide plate 505 is fixedly connected with a fixed block 508, and the front and back ends of the inner wall of the fixed box 2 are fixedly connected with a support 509, and the front and back ends of the top of the fixed box 2 are movably connected with a threaded turning handle 510, and the bottom of the threaded turning handle 510 passes through the bottom of the support 509 and is movably connected to a triangular block 511 through a bearing seat.

[0027] refer to Figure 3 A sliding groove 6 is provided on the surface of the connecting plate 503 and the rectangular plate 504 and at a position corresponding to the slide plate 505 , and the sliding groove 6 is used in conjunction with the slide plate 505 .

[0028] As a technical optimization solution of the present invention, the slide 505 can move back and forth inside the slide 6 through the setting of the slide 6, and at the same time play a limiting role, avoiding the phenomenon of displacement of the slide 505 during the movement.

[0029] refer to Figure 3 Springs 7 are provided at the top and bottom of the inner cavity of the trapezoidal plate 507, and the front end and back end of the spring 7 are fixedly connected to the back end of the slide plate 505 and the back end of the inner wall of the trapezoidal plate 507 respectively.

[0030] As a technical optimization solution of the present invention, the setting of the spring 7 can assist the slide plate 505 in working and play a role of reset buffer, thereby avoiding the slide plate 505 being unable to reset after moving, resulting in the machine being unable to continue working.

[0031] refer to Figure 3 A groove 8 is provided on the surface of the block 506 , and the groove 8 cooperates with the block 506 for use.

[0032] As a technical optimization solution of the present invention, the setting of the groove 8 can assist the block 506 in working and at the same time play a limiting role, avoiding the phenomenon that the width of the groove 8 is too narrow and causes the H-shaped fixing rod 502 to be stuck inside the groove 8.

[0033] refer to Figure 3 The left and right sides of the inner wall of the fixed box 2 are fixedly connected with reinforcement blocks 9 , and the inner side of the reinforcement block 9 is fixedly connected to the surface of the rectangular plate 504 .

[0034] As a technical optimization solution of the present invention, the provision of the reinforcing block 9 can assist the rectangular plate 504 in its work and at the same time play a reinforcing role, thereby avoiding the phenomenon of the rectangular plate 504 shaking due to excessive load.

[0035] refer to Figure 3 The inner cavity of the support 509 is provided with an oblique thread, and the support 509 is used in conjunction with the threaded handle 510.

[0036] As a technical optimization solution of the present invention, the support 509 is provided to assist the threaded turning handle 510 in working, thereby preventing the threaded turning handle 510 from slipping and loosening during the rotation process.

[0037] The working principle and use process of the present invention are as follows: before using the handheld cart body 1 to transport construction materials, the support legs 4 can be bent and rotated 90 degrees clockwise. The rotation of the support legs 4 drives the rotating rod 3 and the rotating wheel 501 to rotate synchronously. The rotation of the rotating wheel 501 drives the H-shaped fixed rod 502 to rotate accordingly. Then, the threaded handle 510 is manually rotated. The threaded handle 510 rotates clockwise to cooperate with the support 509 to screw downward into the interior of the fixed box 2, and drives the triangular block 511 to move accordingly. The triangular block 511 moves downward to contact one side of the fixed block 508 and force the fixed block 508 to move backward. The fixed block 508 moves backward to drive the slide plate 505 The sliding groove 6 moves stably on the surface of the connecting plate 503 and the rectangular plate 504, and the sliding plate 505 moves and compresses the spring 7 to work, driving the block 506 to move backward. The block 506 moves backward and cooperates with the groove 8 to insert into the surface of the H-shaped fixing rod 502. The H-shaped fixing rod 502 cannot rotate, so the rotating wheel 501 cannot rotate. The rotating wheel 501 cannot rotate, so the rotating rod 3 and the support leg 4 cannot rotate. The support leg 4 cannot rotate and is fixed in position, keeping it away from the ground, making it convenient for the user to push the cart body 1 to move without hindrance. Similarly, the support leg 4 is lowered to contact the ground to assist the cart body 1 in supporting and fixing it to avoid tilting and overturning.

[0038] In summary: the construction material sales and transportation device, through the cooperation of the trolley body 1, the fixing box 2, the rotating rod 3, the legs 4, the locking mechanism 5, the rotating wheel 501, the H-shaped fixing rod 502, the connecting plate 503, the rectangular plate 504, the slide plate 505, the clamping block 506, the trapezoidal plate 507, the fixing block 508, the support 509, the threaded turning handle 510 and the triangular block 511, solves the problem that most existing trolleys are manually operated and the trolley legs cannot be folded and stored and easily touch the ground to cause obstruction, thus affecting the convenience of transportation.
