Description

Technical Field

[0001] The utility model relates to a trolley. Background Art

[0002] During the construction of roads and bridges, in places where motor vehicles are inconvenient to use, or when carrying light items over short distances, a wheelbarrow is an indispensable transport tool, which has the characteristics of low cost, simple maintenance, convenient operation, light weight, etc. However, the publication number is CN 214689553 U, and the name is a new type of construction wheelbarrow. Its design structure is relatively complex, which increases the production cost. In addition, if the power supply is out of power during use, the unloading is no different from the previous wheelbarrows that rely on manpower to tilt the bucket before unloading. It also needs to be charged, and the wheelbarrow cannot be used during charging, which is very inconvenient and affects its practicality. In addition, most of the roads on construction sites are rugged, and when transporting goods, bumps and the like will occur, which makes it difficult to control the wheelbarrow, and at the same time, damage will be caused to the transported goods. In addition, the wheelbarrow can only transport some items such as sand, cement or some small items, but cannot transport relatively long goods such as some steel bars and wooden boards. The types of goods transported by the wheelbarrow have certain limitations and a small scope of application. Summary of the invention

[0003] The utility model provides a trolley to solve the deficiencies of the prior art.

The T-shaped plug-in strips and the T-shaped plug-in grooves are matched and plugged together to fix the cart on the bottom plate. A long strip through hole is arranged at the front end of the bottom plate, and a baffle is arranged at the rear end. The T-shaped plug-in strip is arranged in the long strip through hole; the front ends of the side vertical plates on the left and right sides of the cart are respectively provided with long strip through holes, and the front ends of the two side vertical plates on the opposite sides are respectively provided with grooves, and the two sides of the plug-in plate are respectively inserted into the long strip through holes and slidably connected thereto; shock absorbing devices are respectively arranged on the left and right sides of the bottom of the bottom plate, and the two shock absorbing devices are fixed on a fixed shaft I, and wheels are rotatably connected at both ends of the fixed shaft I.

[0017] The handcart of the utility model comprises a bottom plate 1, a cart 2 and wheels 3. Shock absorbing devices are respectively arranged on the left and right sides of the bottom of the bottom plate 1. The two shock absorbing devices are fixed on a fixed shaft Ⅰ23. Wheels 3 are rotatably connected at both ends of the fixed shaft Ⅰ23.

[0018] The shock absorbing device comprises an upper fixing seat 16, a lower fixing seat 17 and a mounting block 18. The upper end of the upper fixing seat 16 is fixedly connected to the bottom of the base plate 1, and the outer loose edge of the lower fixing seat 17 is fixed to the mounting block 18 by bolts. A cavity 19 is provided in the lower fixing seat 17. The convex edge at the bottom end of the upper fixing seat 16 is placed in the cavity 19 and is engaged with the cavity 19 and slidably connected thereto. A compression spring 20 is provided at the bottom center of the cavity 19, and shock absorbing dampers 21 are provided at the four corners. The compression spring 20 and the shock absorbing damper 21 are provided at the four corners. The upper ends of the mounting blocks 18 are respectively fixedly connected to the bottoms of the upper fixing seats 16. The arrangement of the compression springs 20 can elastically support the upper fixing seats 16, so as to weaken the vibration force generated by the cart. The arrangement of the shock absorbing damper 21 can be used to suppress the repeated rebound of the compression springs 20, thereby improving the shock absorbing effect of the compression springs 20. A through hole 22 is provided on the side wall of the mounting block 18. The two ends of the fixed shaft I 23 respectively pass through the through holes 22 on both sides and are fixedly connected thereto. The wheels 3 are rotatably connected to the outer walls of the two ends of the fixed shaft I 23.

[0019] Support legs 4 are respectively provided on the left and right sides of the lower rear end of the base plate 1, and a handle 5 is provided on the rear end face. The other end of the handle 5 is covered with an anti-skid rubber sleeve 25, which can play an anti-skid role and increase the friction between the staff's hands and the handle 5; mud scrapers 24 are provided on the left and right sides of the bottom of the base plate 1, and the front end of the mud scraper 24 is clearance-matched with the outer contour of the wheel 3, and the mud scraper 21 can scrape off the mud stuck on the wheel 3.

[0020] The bottom plate 1 is provided with T-shaped plug strips 6 on the left and right sides respectively, and the bottom of the truck bed 2 is provided with long T-shaped plug grooves 7 on the left and right sides respectively. The T-shaped plug strips 6 and the T-shaped plug grooves 7 are plugged together to fix the truck bed 2 on the bottom plate 1. The front end of the bottom plate 1 is provided with a long through hole 8, and the rear end is provided with a baffle 9. A T-shaped plug strip 10 is provided in the long through hole 8. The T-shaped plug strip 10 and the baffle 9 can fix and limit the position of the truck bed 2 to prevent it from sliding off the bottom plate 1 during use.

[0021] The front ends of the side vertical plates on the left and right sides of the truck bed 2 are respectively provided with long strip through holes 11, and the front ends of the two side vertical plates on the opposite sides are respectively provided with grooves 12. The two sides of the plug plate 13 are respectively inserted into the long strip through holes 11 and slidably connected thereto; the lower parts of the left and right end surfaces of the plug plate 13 are respectively provided with fixed shafts II 14, and the fixed shafts II 14 on both sides respectively pass through the long strip through holes 11 on both sides, and are provided with limit blocks 15 at their ends.

[0022] When the handcart of the utility model is in use, the bucket 2 and the bottom plate 1 can be plugged together through the T-shaped plug strip 6 and the T-shaped plug groove 7, and the staff can use the handcart to transport materials such as sand and cement. When the staff pushes the handcart to the designated location, first, lift the plug plate 13 upwards, and put the fixed shafts II 14 on both sides of the bottom on the bottom edge of the groove 12. At this time, the front end of the bucket 2 is in an open state, and then, the handle 5 is gently lifted upwards to tilt the handcart forward at a certain angle. At this time, the materials in the bucket 2 will fall to the ground from the front end opening due to their own gravity, and the unloading is completed; when the staff separates the bucket 2 from the bottom plate 1, the handcart can be used to transport some relatively long materials such as steel bars, wooden boards, etc., thereby expanding the application range of the handcart.
