[0022] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0023] As attached Figure 1 To be continued Figure 5 As shown: This embodiment provides a broiler cart, including a frame 2. Push handles 1 are installed at both ends of the surface of the frame 2. Extended side rails 3 are connected to both sides of the surface of the frame 2. An even number of moving wheels 4 are installed at the bottom of the frame 2. Auxiliary feeding guide devices 5 are installed at both ends of the frame 2. An even number of reinforcing beams 21 are provided inside the frame 2. An inner frame 22 is installed between the reinforcing beams 21. Several rollers 23 are installed in the inner frame 22. Side connecting seats 24 are installed on the outer surfaces of both ends of the reinforcing beams 21. An even number of connecting platforms 25 are installed on the side surfaces of the reinforcing beams 21. A baffle 51 is provided inside the auxiliary feeding guide device 5. A hanging connector 52 is connected above the baffle 51. A frame connecting plate 53 is connected below the baffle 51. Hinged swing rods 55 are fixed on both sides of the baffle 51. A swing bushing 54 is fixed at the end of the hinged swing rod 55. The fastening connector 52 has a nested plate 521 inside, and an adjusting shaft 523 is connected to the nested plate 521. Several hanging ears 522 are installed on the adjusting shaft 523. The surface of the nested plate 521 has a hollow groove 524. Side slide rails 525 are installed on the inner walls of both sides of the hollow groove 524. A pull handle 526 is provided between the side slide rails 525. A pull rope groove 527 is provided inside the nested plate 521. A locking piece 528 is provided at the end of the pull rope groove 527. A rear support spring 529 is connected behind the locking piece 528.

[0024] Furthermore, the push handle 1 is inserted into the sleeves on both sides of the extended side block 3 and welded to fix it, while the bottom of the extended side block 3 is welded to the reinforcing beam 21, so that the frame 2 moves when the push handle 1 is pushed.

[0025] Furthermore, the inner frame 22 is hollow inside. By arranging the rollers 23 in a straight line, and with the assistance of the rollers 23 and the extended side guards 3 on both sides, it is easy to load and unload goods onto and off the frame 2, making the loading process easier and more efficient.

[0026] Furthermore, the baffle 51 is mainly fixed to the push handle 1 by the upper fastening connector 52, and together with the extended side guards 3 set on both sides, it forms a fence frame to prevent the goods from shifting or falling during transportation.

[0027] Furthermore, the frame connecting plate 53 is mainly used to cooperate with the inner frame 22. Under the hinged swing of the hinged swing rods 55 on both sides of the baffle 51, the frame connecting plate 53 is mounted on one side of the inner frame 22 to form a guide ramp for loading and unloading goods.

[0028] Furthermore, the nested plate 521 is mainly used in the nested cavity 511 nested in the baffle 51. The length of the nested plate 521 is adjusted to allow the extended portion to be used for the hanging ear 522 to adapt to the height of the push handle 1 for fastening.

[0029] Furthermore, the pull handle 526, mainly through the connected pull rope, can compress the rear support spring 529 by means of the locking part 528 connected to the end of the pull rope when it is pulled up, so that the locking part 528 disengages from the locking part of the groove wall 512 and re-locks into the groove wall 512 of the appropriate height.

[0030] The specific working principle is as follows: This invention welds and fixes the reinforcing beam 21 on the frame 2 to the connecting platform 25 to the extended side guard 3. Then, the push handle 1 is installed in the sleeve on the extended side guard 3. With the assistance of the moving wheels 4 at the bottom of the frame 2, the frame 2 is pushed. When loading goods, the auxiliary guide device 5 engaged on the push handle 1 is adjusted to adjust the height of the hanging connector 52 above the baffle 51. This allows the nesting plate 521 to disengage from the grooves 512 on both sides of the nesting cavity 511 under the cooperation of the pull handle 526, the pull rope groove 527, and the engaging part 528. After the height change, the hanging ear 522 engages with the push handle 1, thereby forming a limit on the goods from all sides to prevent the goods from shifting or falling during transportation. At the same time, when unloading, the rollers 23 on the inner frame 22 can also slide the goods, allowing for better loading and unloading.

[0031] Please see the appendix Figure 2 Appendix Figure 3 and appendix Figure 6 As shown: The frame 2 has an even number of reinforcing beams 21, an inner frame 22 is installed between the reinforcing beams 21, several rollers 23 are installed in the inner frame 22, side connecting seats 24 are installed on the outer surfaces of both ends of the reinforcing beams 21, and an even number of connecting platforms 25 are installed on the side surfaces of the reinforcing beams 21; the auxiliary guide device 5 has a baffle 51, a hanging connector 52 is connected above the baffle 51, a frame connecting plate 53 is connected below the baffle 51, and hinged swing rods 55 are fixed on both sides of the baffle 51, with swing bushings 54 fixed at the ends of the hinged swing rods 55. A fixed plate 531 is provided inside the frame connecting plate 53. An even number of sliding grooves 532 are provided on the fixed plate 531. A tension hanging plate 535 is nested inside the fixed plate 531. A limit sliding component 533 is installed in the sliding groove 532. A slanted groove 534 is provided on the top of the fixed plate 531. A hanging strip 536 is fixed on the inner surface of the top of the tension hanging plate 535.

[0032] Furthermore, the fixed plate 531 mainly serves to connect with the bottom of the baffle 51, hide the stretching plate 535 when not in use, and pull the stretching plate 535 outward when in use to compensate for the length.

[0033] Furthermore, the hanging strip 536 and the tension hanging plate 535 are an integrated structure, so that after the tension hanging plate 535 is pulled outward, the hanging strip 536 can be engaged with the inner frame 22, thereby forming a connection with the inner frame 22.

[0034] Furthermore, the oblique groove 534 opened at the upper end of the fixed plate 531 is mainly used to finely adjust the angle of the tension hanging plate 535 during the hanging process, and the nested rod inside the limiting slide 533 is used as a connecting rod with the tension hanging plate 535 to form a corresponding length compensation when the angle of the tension hanging plate 535 is adjusted.

[0035] The specific working principle is as follows: The present invention utilizes the hinged swing rods 55 and swing bushings 54 on both sides of the baffle 51 to form an angle adjustment. During the adjustment, the bottom of the fixed plate 531 pulls the stretch hanging plate 535 outward. During the outward pulling process, the limiting slide 533 moves in the slide groove 532. When it reaches the end of the fixed plate 531, the stretch hanging plate 535, with the assistance of the limiting slide 533 and the inclined groove 534, sets the hanging strip 536 on the inner wall of the inner frame 22, so that one side of the inner frame 22 forms an inclined guide slope. Then, when the roller 23 moves the goods in the inner frame 22, the goods can be directly guided to the storage or stacking position through the inclined guide slope.

[0036] Please see the appendix Figure 2 Appendix Figure 7 To be continued Figure 8 As shown: The frame 2 has an even number of reinforcing beams 21, an inner frame 22 is installed between the reinforcing beams 21, several rollers 23 are installed in the inner frame 22, side connecting seats 24 are installed on the outer surfaces of both ends of the reinforcing beams 21, and an even number of connecting platforms 25 are installed on the side surfaces of the reinforcing beams 21; the extended side rail 3 has a rod frame 31, a side rail 32 is hinged on the rod frame 31, a rear support assembly 33 is installed behind the side rail 32, and a tension spring frame 34 is installed on the side rail 32. The rear support assembly 33 is provided with a connecting rod support 331. The outer wall of the connecting rod support 331 is connected to a connecting beam support plate 332. The connecting rod support 331 is nested with an inner sleeve groove 333. The inner sleeve groove 333 is nested with a top rod 334. The top of the inner sleeve groove 333 is provided with a groove opening 335. A pin 336 passes through the groove openings 335. Both ends of the top rod 334 are provided with locking pin holes 3341.

[0037] Furthermore, an extended side guard 3 is provided with a set, which is installed opposite to the connecting platform 25. The connecting platform 25 can fix the pole frame 31, so that its side guard 32 stands vertically on the connecting platform 25.

[0038] Furthermore, the pole 31 and its side rails 32 can be hinged and swing. When the rear support assembly 33 is adjusted, the side rails 32 can be placed horizontally, allowing for the loading of more goods in a more spacious area.

[0039] Furthermore, the tension spring frame 34 is pulled inward by the tension spring installed inside the side guardrail 32, so that when loading goods, the tension spring frame 34 can be lifted and locked onto the surface of the goods, thereby increasing the stability during the pushing process of the goods.

[0040] Furthermore, one end of the connecting rod support 331 is nested on the rod frame 31, while the other end is wall-fixed to one side of the reinforcing beam 21, and the connecting beam support plate 332 is vertically fixed to the surface of the reinforcing beam 21.

[0041] Furthermore, the inner sleeve groove 333 is mainly used for the sliding adjustment of the top rod 334, and the locking pin holes 3341 on the top rod 334 are respectively opened at both ends of the top rod 334, and the pin 336 passing through the groove opening 335 passes through the locking pin holes 3341.

[0042] Furthermore, the top of the top rod 334 is fixed to the outer wall of the side barrier 32. When the side barrier 32 swings, the length of the top rod 334 is reduced by the inner sleeve groove 333, while its fixed position remains unchanged, so that it always maintains force support for the side barrier 32.

[0043] The specific working principle is as follows: This invention fixes the rod frame 31 to the connecting platform 25. Under the condition of operation within the pushing range, the side barrier 32 can be hinged and swung. During the swing, the rear support assembly 33 needs to be adjusted so that the nested top rod 334, which plays a limiting and fixing role on the inner sleeve slide groove 333 in the connecting rod support 331, can be adjusted. The pin 336 is pulled inward and outward from the locking pin hole 3341 and disengaged from the top rod 334. Then, the top rod 334 is partially retracted into the slide groove opening 335 and the pin 336 is reinserted into another locking pin hole 3341. The side barrier 32 is placed horizontally and the bottom is fixed again by the top rod 334. After expansion, its loading area is increased, allowing more goods to be loaded and pushed to the designated position.
