Description

Technical Field

[0001] This utility model relates to the field of construction trolleys, specifically a construction trolley. Background Technology

[0002] Construction is a complex process that encompasses multiple stages from project planning to the final delivery of the building. It is of great significance, as it not only creates living spaces for people, ensures their safety and promotes social stability and harmony, but also serves as an important part of the economy, driving social and economic development, stimulating upstream and downstream industries, attracting investment, and meeting social functional needs.

[0003] Handcarts are very common in the construction industry. One common type of handcart on the market usually consists of a cart bed, a handle, and wheels. When in use, building materials such as sand and gravel are loaded into the cart bed for transportation. It is simple to operate and inexpensive.

[0004] However, this common handcart has some problems in actual use. When unloading, the entire handcart is usually tilted over. After tilting, some sand and gravel often remain in the cart, which needs to be removed manually with a shovel. This process is extremely inconvenient and seriously affects work efficiency. Therefore, further improvements are needed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a construction trolley to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction trolley, comprising a trolley body and a trolley door, the top of the trolley door being rotatably mounted to the end of the trolley body, a pin being fixedly mounted at the bottom of the trolley door, a first limiting block being mounted on the bottom of the trolley body by a torsion spring, and a second limiting block being connected to the outer wall of the end of the first limiting block by a torsion spring, and a fixing block being fixedly mounted on the outer wall of the second limiting block to the end of the first limiting block, a pressing rod being slidably mounted on the bottom of the trolley body, a baffle being slidably mounted on the bottom of the trolley body, and a spring being fixedly mounted at the end of the baffle, and a through groove and a sliding groove being opened at the bottom of the trolley body.

[0007] By adopting the above technical solution, the unloading process becomes more convenient and efficient. Simply operating the squeezing rod allows the trolley door to open automatically for unloading, effectively increasing the unloading speed and thus improving the overall efficiency of the construction material handling process. Moreover, during the unloading process, the ejection of the baffle effectively prevents sand and gravel from entering the key structures inside the device, avoiding problems such as wear or jamming of parts caused by sand and gravel accumulation. This reduces the maintenance cost of the device, extends its service life, and ensures the stability and reliability of the device during long-term use, which is conducive to the smooth progress of construction. Compared with traditional handcarts, it is no longer necessary to manually use shovels to clean the sand and gravel remaining in the trolley, reducing manpower input and labor intensity.

[0008] Furthermore, the top of the trolley door is rotatably mounted to the end of the trolley body, and the outer wall of the trolley door is in contact with the inner wall of the trolley body.

[0009] By adopting the above technical solution, the goods are unloaded from the bottom of the trolley. Compared with the traditional trolley, this unloading method eliminates the need for manual shovel cleaning of residual sand and gravel in the trolley, reducing manpower input and labor intensity.

[0010] Furthermore, two sets of latches are symmetrically arranged at the bottom of the trolley door, and through slots are provided corresponding to the latches.

[0011] By adopting the above technical solution, the latch controls the opening and closing of the trolley door, ensuring the stability of the device.

[0012] Furthermore, two sets of the first limiting blocks are symmetrically arranged on both sides of the pin, and the first limiting block is designed in an L shape, with the outer wall of the end of the first limiting block away from the second limiting block being arc-shaped.

[0013] By adopting the above technical solution, the first limiting block can be rotated by pushing the squeezing rod, thereby releasing the restriction on the latch and making it easy to open the trolley door.

[0014] Furthermore, the outer wall of the second limiting block is in contact with the outer wall of the pin, and the length of the second limiting block is greater than the distance between the inner wall of the first limiting block and the outer wall of the pin.

[0015] By adopting the above technical solution, the second limit block is firmly locked to the latch, enabling the quick closing of the pushcart door.

[0016] Furthermore, the fixing block is correspondingly provided with the second limiting block, and the outer wall of the fixing block is in contact with the outer wall of the second limiting block, and the length of the fixing block is less than the length of the second limiting block.

[0017] By adopting the above technical solution, the fixed block restricts the rotation direction of the second limiting block, so that the pin can easily enter the second limiting block and be restricted.

[0018] Furthermore, the whole extrusion rod is designed in a "C" shape, and the outer wall of the end of the extrusion rod located inside the cart body is in contact with the outer wall of the first limiting block, and the end of the extrusion rod far from the first limiting block is located outside the cart body.

[0019] By adopting the above technical solution, it is only necessary to push the end of the extrusion rod to unlock the two groups of pins, thereby conveniently opening the cart door.

[0020] Furthermore, the baffle is arranged above the first limiting block and the second limiting block corresponding to the through groove, the sliding groove is arranged corresponding to the baffle, one end of the spring is in contact with the outer wall of the baffle, and the other end of the spring is in contact with the inside of the cart body.

[0021] By adopting the above technical solution, the ejection of the baffle can effectively prevent sand and gravel from entering the key structure inside the device, avoiding problems such as part wear or jamming caused by the accumulation of sand and gravel, reducing the maintenance cost of the device, extending the service life of the device, ensuring the stability and reliability of the device during long-term use, and being beneficial to the smooth progress of construction work.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] By providing a through groove, a sliding groove, a pin, a first limiting block, a second limiting block, a fixing block, an extrusion rod, a baffle and a spring, the present utility model makes the unloading process more convenient and efficient. Only by simply operating the extrusion rod can the cart door be automatically opened for unloading, effectively improving the unloading speed, thereby enhancing the work efficiency of the entire building construction material handling link. Moreover, during the unloading process, the ejection of the baffle can effectively prevent sand and gravel from entering the key structure inside the device, avoiding problems such as part wear or jamming caused by the accumulation of sand and gravel, reducing the maintenance cost of the device, extending the service life of the device, ensuring the stability and reliability of the device during long-term use, and being beneficial to the smooth progress of construction work. Compared with traditional small carts, there is no need for manual use of shovels to clean the residual sand and gravel in the cart hopper, reducing the labor input and labor intensity.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] A type of construction trolley, such as Figure 1 - Figure 7 As shown, the device includes a trolley body 1 and a trolley door 2. The top of the trolley door 2 is rotatably mounted to the end of the trolley body 1, and a pin 201 is fixedly mounted at the bottom of the trolley door 2. A first limiting block 3 is mounted on the bottom of the trolley body 1 by a torsion spring, and a second limiting block 301 is connected to the outer wall of the end of the first limiting block 3 by a torsion spring. The outer wall of the second limiting block 301 is provided with a fixing block 302 fixedly mounted to the end of the first limiting block 3. A pressing rod 4 is slidably mounted on the bottom of the trolley body 1, making the unloading process more convenient and efficient. Simply operating the pressing rod 4 can automatically open the trolley door 2 for unloading, effectively improving the unloading speed and thus improving the overall efficiency of the construction materials. To improve the efficiency of the handling process, a baffle 5 is slidably installed at the bottom of the trolley body 1, and a spring 501 is fixedly installed at the end of the baffle 5. The bottom of the trolley body 1 has a through groove 101 and a sliding groove 102. The pop-out of the baffle 5 can effectively prevent sand and gravel from entering the key structure inside the device, avoiding problems such as wear or jamming of parts caused by sand and gravel accumulation, reducing the maintenance cost of the device, extending the service life of the device, ensuring the stability and reliability of the device in long-term use, and facilitating the smooth progress of construction. Compared with traditional trolleys, it is no longer necessary to manually use shovels to clean the sand and gravel remaining in the trolley, reducing manpower input and labor intensity.

[0035] Please refer to Figure 1 - Figure 7 , the top end of the push door 2 is rotatably installed with the end of the cart body 1, and the outer wall of the push door 2 is in contact with the inner wall of the cart body 1, so that the goods are unloaded from the bottom of the cart body 1. Compared with the traditional small cart, this unloading method no longer requires manual use of a shovel to clean the residual sand and gravel in the cart bucket, reducing the labor input and labor intensity.

[0036] Please refer to Figure 1 - Figure 7 , two groups of latch pins 201 are symmetrically arranged at the bottom of the push door 2, and the through slots 101 are arranged corresponding to the latch pins 201, so that the latch pins 201 control the opening and closing of the push door 2 to ensure the stability of the device.

[0037] Please refer to Figure 3 - Figure 7 , two groups of first limit blocks 3 are symmetrically arranged on both sides of the latch pin 201, and the first limit block 3 is integrally designed in an L shape, and the outer wall of the end of the first limit block 3 away from the second limit block 301 is arranged in an arc shape, so that by pushing the extrusion rod 4, the rotation of the first limit block 3 is realized, thereby releasing the restriction on the latch pin 201 and conveniently opening the push door 2.

[0038] Please refer to Figure 4 and Figure 5 , the outer wall of the second limit block 301 is in contact with the outer wall of the latch pin 201, and the length of the second limit block 301 is greater than the distance between the inner wall of the first limit block 3 and the outer wall of the latch pin 201, so that the second limit block 301 firmly locks the latch pin 201 to realize the quick closing of the push door 2.

[0039] Please refer to Figure 3 - Figure 7 , the fixing block 302 is arranged corresponding to the second limit block 301, and the outer wall of the fixing block 302 is in contact with the outer wall of the second limit block 301, and the length of the fixing block 302 is less than the length of the second limit block 301, so that the fixing block 302 restricts the rotation direction of the second limit block 301, realizing that the latch pin 201 can easily enter the second limit block 301 and be restricted.

[0040] Please refer to Figure 2 - Figure 7 , the extrusion rod 4 is integrally designed in a "匚" shape, and the outer wall of the end of the extrusion rod 4 located inside the cart body 1 is in contact with the outer wall of the first limit block 3, and the end of the extrusion rod 4 away from the first limit block 3 is located outside the cart body, so that by only pushing the end of the extrusion rod 4, the unlocking of the two groups of latch pins 201 can be realized, thereby conveniently opening the push door 2.

[0041] Please refer to Figure 3 - Figure 6The baffle 5 is located above the first limiting block 3 and the second limiting block 301 and is correspondingly set to the through groove 101. The sliding groove 102 is correspondingly set to the baffle 5. One end of the spring 501 is in contact with the outer wall of the baffle 5, and the other end of the spring 501 is in contact with the inside of the trolley body 1. This allows the ejection of the baffle 5 to effectively prevent sand and gravel from entering the key structure inside the device, avoiding problems such as wear or jamming of parts caused by sand and gravel accumulation, reducing the maintenance cost of the device, extending the service life of the device, ensuring the stability and reliability of the device during long-term use, and facilitating the smooth progress of construction.

[0042] The working principle of this utility model is as follows: When the trolley body 1 needs to unload, the pressing rod 4 is manually pressed first, so that the pressing rod 4 slides and presses the first limiting block 3. After being pressed, the first limiting block 3 rotates, which drives the second limiting block 301 to rotate away from the pin 201 until the second limiting block 301 releases the restriction on the pin 201. At this time, the restriction of the pin 201 on the baffle 5 is also released. The baffle 5 slides out under the action of the spring 501, blocking the first limiting block 3, the second limiting block 301 and the fixing block 302 below, so as to prevent sand and gravel from entering during unloading and affecting the use of the device. At the same time, the trolley door 2 opens automatically from the bottom under the pressure of the building materials in the trolley, realizing complete unloading.

[0043] After unloading is completed, manually push the trolley door 2. The pin 201 will press the second limit block 301 and the baffle 5, causing the second limit block 301 to rotate until the pin 201 enters between the second limit block 301 and the first limit block 3. At this time, the second limit block 301 will reset under the action of the torsion spring, and re-limit the pin 201, thereby realizing the closing and locking of the trolley door 2.
