Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a storage cage, particularly a storage cage chassis assembly. Background Technology

[0002] Storage cages are important logistics containers in warehousing and transportation, effectively improving space utilization and operational efficiency. One example, disclosed in the Chinese Patent Database (CN205345964U), includes a chassis and front, left, right, and rear side panels mounted on the chassis. The chassis comprises a front chassis, a left chassis, a right chassis, and a rear chassis. A front towing mechanism is located in the center of the left chassis, and a rear towing mechanism is located in the center of the right chassis. Casters are located at the four corners of the chassis, and foot cups are located at the four corners of the chassis, with a support frame on the outer side of each foot cup. Forklift bays are located on both sides of the center of the chassis.

[0003] To facilitate the connection and synchronous transport of two storage cages, a certain type of existing storage cage has a connecting plate with rope holes on one side of the chassis. The two storage cages are connected by the rope holes and ropes. However, since the connecting plate is fixed, it occupies a certain space when the storage cage is used alone, increasing the space occupied by the storage cage. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a storage cage chassis assembly that can reduce space occupancy.

[0005] The objective of this utility model can be achieved through the following technical solution: a storage cage chassis assembly, including a base plate and casters installed around the bottom wall of the base plate. A hollow crossbeam is also horizontally fixed on the bottom wall of the base plate. The crossbeam extends front and back, and there are two crossbeams arranged side by side. The characteristic is that a limit rod is vertically fixed on the outer side of one of the long sides of the two crossbeams. A groove is formed between the limit rod and the corresponding crossbeam. A connecting plate is slidably arranged in the groove. The outer end of the connecting plate is provided with a connecting hole that extends through the left and right sides. The sliding connecting plate can allow the outer end of the connecting plate to extend out of the coverage area of ​​the base plate. A stop block is vertically formed on the inner side wall of the connecting plate. The limit rod is arranged between the corresponding connecting hole and the stop block. The stop block can be pressed against the corresponding limit rod by sliding the connecting plate.

[0006] When it is necessary to connect two storage cages together, the specific operation is as follows: First, pull out the connecting plate so that its outer end extends out of the coverage area of ​​the bottom plate. Then, adjust the position of the two storage cages so that the position of the connecting plate is corresponding. Next, make the connecting plates on the two storage cages stick together and align the connecting holes. Finally, use ropes or bolts passing through the connecting holes to fix the two connecting plates together, thereby locking the two storage cages together and facilitating the synchronous movement of the two storage cages.

[0007] At the same time, a connecting plate is designed to move back and forth relative to the base plate. By sliding the connecting plate, it can be extended into or out of the coverage area of ​​the base plate, thereby reducing the space occupied by the storage cage when used alone.

[0008] In the aforementioned storage cage chassis assembly, the two long sides of the crossbeam are equipped with the aforementioned limiting rods. The number of connecting plates and limiting rods are the same and their positions correspond one-to-one, in order to enhance the locking strength and stability of the two storage cages.

[0009] In the aforementioned storage cage chassis assembly, the cross-section of the long side of the crossbeam is U-shaped and matches the connecting plate. The long side of the crossbeam includes two baffles arranged side by side, and the upper and lower sides of the inner end of the connecting plate press against the corresponding two baffles to provide better support for the connecting plate and improve the stability of the connection or sliding.

[0010] In the aforementioned storage cage chassis assembly, the limiting rod includes an inner circular rod and an outer circular sleeve, with the outer circular sleeve rotatably fitted onto the inner circular rod. The two ends of the inner circular rod are respectively fixed to two corresponding baffle portions, and the outer circumferential surface of the outer circular sleeve presses against the side surface of the corresponding connecting plate, so as to form rolling friction between the connecting plate and the limiting rod, thereby reducing wear and improving the smoothness of the sliding of the connecting plate.

[0011] In the aforementioned storage cage chassis assembly, the outer sleeve and the inner rod are engaged through circumferential surface contact. The length of the outer sleeve is slightly less than the distance between the corresponding two baffles. That is, the forming of the limiting rod only depends on the outer sleeve and the inner rod, which has the advantage of being easy to assemble and install.

[0012] In the aforementioned storage cage chassis assembly, each baffle section has a vertically penetrating mounting hole, and the two ends of the inner round rod are respectively inserted into the corresponding two mounting holes, and the inner round rod is fixed to the corresponding baffle section by welding.

[0013] Compared with existing technologies, this storage cage chassis assembly has the following advantages: 1. The connecting plate is designed to move back and forth relative to the base plate. By sliding the connecting plate, it can be extended into or out of the coverage area of ​​the base plate, thereby reducing the space occupied by the storage cage when used alone.

[0014] 2. The limiting rod includes an inner round rod and an outer round sleeve, and the outer round sleeve is rotatably fitted onto the inner round rod so that rolling friction is formed between the connecting plate and the limiting rod to reduce wear and improve the smoothness of the sliding of the connecting plate.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1: As Figure 1 As shown, the storage cage chassis assembly includes a horizontally arranged base plate 1 and casters 2 installed around the bottom wall of the base plate 1. The casters 2 are existing products and can be purchased directly from the market.

[0022] Specifically A hollow crossbeam 3 is horizontally fixed to the bottom wall of the base plate 1. The crossbeam 3 extends front to back, and there are two crossbeams 3 arranged side by side. Preferably, the crossbeams 3 and the base plate 1 are welded together. In actual use, the crossbeams 3 work with a forklift to lift and move the storage cage. Specifically, the two forks of the forklift are inserted into the inner holes of the two crossbeams 3, and then the forklift forks move upward to suspend the storage cage.

[0023] like Figure 2 and Figure 3 As shown, the crossbeam 3 includes two long sides arranged side by side. A limiting rod 4 is vertically fixed to the outer side of one of the long sides of each crossbeam 3. A groove 5 is formed between the limiting rod 4 and the corresponding crossbeam 3. A connecting plate 6 is slidably arranged in the groove 5. The connecting plate 6 is elongated, and its length extends forward and backward. A connecting hole 6a is provided at the outer end of the connecting plate 6, extending horizontally. The axis of the connecting hole 6a is horizontal, and sliding the connecting plate 6 allows its outer end to extend beyond the coverage area of ​​the base plate 1. A stop block 6b is vertically formed on the inner side wall of the connecting plate 6. The limiting rod 4 is positioned between the corresponding connecting hole 6a and the stop block 6b. Sliding the connecting plate 6 allows the stop block 6b to press against the corresponding limiting rod 4.

[0024] like Figure 4As shown, when it is necessary to connect two storage cages together, the specific operation is as follows: First, pull out the connecting plate 6 so that its outer end extends out of the coverage area of ​​the bottom plate 1. Then, adjust the position of the two storage cages so that the position of the connecting plate 6 corresponds. Then, make the connecting plates 6 on the two storage cages stick together and align the connecting holes 6a. Finally, use the rope or bolt passing through the connecting holes 6a to fix the two connecting plates 6 together, thereby locking the two storage cages together, so as to facilitate the synchronous movement of the two storage cages.

[0025] At the same time, a connecting plate 6 is provided that can move back and forth relative to the base plate 1. By sliding the connecting plate 6, it can be extended into or out of the coverage area of ​​the base plate 1, thereby reducing the space occupied by the storage cage when used alone.

[0026] The preferred crossbeam 3 has limiting rods 4 on the outer sides of both long sides. The number of connecting plates 6 and limiting rods 4 are the same and their positions correspond one-to-one to enhance the locking strength and stability of the two storage cages. Each connecting plate 6 has at least two connecting holes 6a, and the multiple connecting holes 6a on the same connecting plate 6 are arranged side by side.

[0027] To further explain, the cross-section of the long side of the crossbeam 3 is U-shaped and matches the connecting plate 6. The long side of the crossbeam 3 includes two baffle portions 3a arranged side by side, and the upper and lower sides of the inner end of the connecting plate 6 press against the corresponding two baffle portions 3a, so that the connecting plate 6 can be better supported and the stability of connection or sliding can be improved.

[0028] like Figure 3 As shown, the installation method of the limiting rod 4 is as follows: The limiting rod 4 includes an inner circular rod 4a and an outer circular sleeve 4b, and the outer circular sleeve 4b is rotatably sleeved on the inner circular rod 4a; the two ends of the inner circular rod 4a are respectively fixed to the corresponding two baffle portions 3a, and the outer circumferential surface of the outer circular sleeve 4b abuts against the side of the corresponding connecting plate 6, so that rolling friction is formed between the connecting plate 6 and the limiting rod 4 to reduce wear and improve the smoothness of sliding of the connecting plate 6.

[0029] The inner cylindrical rod 4a and the outer cylindrical sleeve 4b are fitted together as follows: the outer cylindrical sleeve 4b and the inner cylindrical rod 4a are fitted together through circumferential surface contact. The length of the outer cylindrical sleeve 4b is slightly less than the distance between the corresponding two baffle portions 3a. That is, the forming of the limiting rod 4 only depends on the outer cylindrical sleeve 4b and the inner cylindrical rod 4a, which has the advantage of convenient assembly and installation. Preferably, the crossbeam 3 is an integral structure.

[0030] The inner round rod 4a is installed as follows: each baffle part 3a has a vertical through hole, the two ends of the inner round rod 4a are inserted into the corresponding two mounting holes respectively, and the inner round rod 4a is fixed to the corresponding baffle part 3a by welding.

[0031] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference lies in the way the inner rod 4a and the outer sleeve 4b are fitted together, as follows: Both ends of the inner rod 4a are provided with ball bearings, and the inner and outer rings of the ball bearings are fixedly connected to the inner rod 4a and the outer sleeve 4b, respectively.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
