Description

Technical Field

[0001] The utility model relates to the technical field of safe transport devices, in particular to a safe transport and anti-smashing device for civil engineering construction. Background Art

[0002] Currently in civil construction, the most commonly used manpower transportation tool is the cart. The required materials are loaded into the cart and the cart can be pushed to transport the materials to the construction site for use, saving time and effort. Due to its flexible and convenient use, it is widely used in civil engineering construction.

[0003] In construction sites, the road surface in the construction site is often not flat, and there will be some slopes at different angles. When some existing carts are going uphill, the carts are often in a tilted state, which causes the items transported in the carts to fall out easily. When falling out, these items will move downward along the slope, and may hit the person pushing the cart during the movement, thereby endangering the person's safety. In order to solve this technical problem, the utility model proposes a safe handling and anti-smashing device for civil engineering construction. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a safe handling and anti-smashing device for civil engineering construction includes a cart body 1, the outer surface of the cart body 1 is connected to a limiting shell 2, the outer surface of the cart body 1 is connected to a blocking block 3, the cart body 1 will fix the position of the limiting shell 2 so that the limiting shell 2 cannot move, and the cart body 1 will also fix the position of the blocking block 3 so that the blocking block 3 cannot move.

[0024] The outer surface of the blocking block 3 is connected with teeth 4, and the inner surface of the limiting shell 2 is rotatably connected with a baffle 5. The blocking block 3 will fix the position of the teeth 4 so that the teeth 4 cannot move, and the limiting shell 2 will limit the position of the baffle 5 so that the baffle 5 can only rotate but cannot move forward or backward.

[0025] The inner rotation of the limiting shell 2 is connected to the steering rod 6, and the outer surface of the steering rod 6 is connected to the limiting block 7. The limiting shell 2 will limit the position of the steering rod 6 so that the steering rod 6 can only rotate but cannot move horizontally or vertically. The steering rod 6 will fix the position of the limiting block 7, and when the limiting block 7 moves, it will move with the steering rod 6.

[0026] The outer surface of the limit block 7 is connected to a pin 8, one end of the steering rod 6 is in contact with a handle 9, and the outer surface of the handle 9 is connected to a limit plate 10. The limit block 7 will fix the position of the pin 8. When the handle 9 is in contact with the steering rod 6, the handle 9 cannot rotate. The handle 9 will fix the position of the limit plate 10, and when the handle 9 moves, it will move with the limit plate 10.

[0027] A limiting groove 11 is provided inside the handle 9, an adjusting hole 12 is provided inside the handle 9, and a limiting mechanism 13 is provided inside the handle 9. The inner wall of the limiting groove 11 is relatively smooth, and other objects are subject to less friction when moving in the limiting groove 11. The inner wall of the adjusting hole 12 is also relatively smooth, and other objects are subject to less friction when moving on the inner wall of the adjusting hole 12.

[0028] The limiting mechanism 13 includes an insert rod 1301, the outer surface of the insert rod 1301 is slidably connected to the inside of the handle 9, and the outer surface of the insert rod 1301 is slidably connected to the inside of the limit block 7. The handle 9 will limit the direction in which the insert rod 1301 can move, so that the moving position of the insert rod 1301 will not deviate. The positions of the handle 9 and the limit block 7 are limited by inserting the insert rod 1301 into the inside of the limit block 7 so that they are in the same straight line.

[0029] The outer surface of the insertion rod 1301 is connected to a retaining ring 1302, and the outer surface of the retaining ring 1302 is slidably connected to the inner wall of the adjustment hole 12. The insertion rod 1301 will fix the position of the retaining ring 1302, and when the retaining ring 1302 moves, it will move with the insertion rod 1301. The adjustment hole 12 will limit the moving position of the retaining ring 1302, thereby avoiding deviation in the moving position of the retaining ring 1302.

[0030] The outer surface of the retaining ring 1302 is connected to a spring 1303, and one end of the spring 1303 away from the retaining ring 1302 is connected to the inner wall of the adjustment hole 12. The spring 1303 is sleeved on the outer surface of the insertion rod 1301. The retaining ring 1302 will fix the position of the spring 1303. The retaining ring 1302 is pushed by the spring 1303, so that the insertion rod 1301 cannot be easily moved out of the handle 9. The adjustment hole 12 will limit the position of the spring 1303, and the insertion rod 1301 will limit the position of the spring 1303.

[0031] One end of the insertion rod 1301 is connected to a transmission block 1304, and the outer surface of the transmission block 1304 contacts one end of the handle 9. The transmission block 1304 will fix the position of the insertion rod 1301. The insertion rod 1301 can be pulled out of the limit block 7 by moving the transmission block 1304. Under the action of the spring 1303, the transmission block 1304 will contact the handle 9.

[0032] The outer surface of the limit block 7 is slidably connected to the inner wall of the limit groove 11, the outer surface of the latch 8 is slidably connected to the inner wall of the slide groove, and the bottom surface of the handle 9 is connected to the support column 14. The limit groove 11 allows the handle 9 to rotate horizontally. The latch 8 provides a central axis for the rotation of the handle 9. The bottom end of the support column 14 is only slightly lower than the bottom end of the cart body 1, so that the bottom of the cart will not hit the ground.

[0033] The outer surface of the baffle plate 5 is rotatably connected to the outer surface of the cart body 1, one end of the steering rod 6 is connected to the outer surface of the baffle plate 5, and the outer surface of the limit plate 10 is meshed with the outer surface of the tooth 4. The baffle plate 5 is used to limit the position of the steering rod 6 so that the steering rod 6 will not be pulled out of the limit shell 2. The meshing of the limit plate 10 with the tooth 4 prevents the limit plate 10 from moving, thereby preventing the handle 9 from rotating vertically. The user can pull the transmission block 1304 and the handle 9 outward to rotate the handle 9 horizontally, thereby separating the limit plate 10 from the tooth 4.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
