Description

Technical Field

[0001] The present invention relates to the field of bathtub packaging, in particular to a bathtub stacking bracket structure and a stacking method thereof. Background Art

[0002] At present, after bathtubs are manufactured, they are usually packaged individually in wooden boxes. This individual packaging method is limited by the internal height of the container and can only be stacked up to 3 layers. Such a cargo capacity will result in high transportation costs. In order to solve this technical problem, a packaging and transportation method that can stack bathtubs together has now emerged. For example, a patent application number 202122120209.X published in Chinese patent documents is titled "A stackable packaging structure for artificial stone bathtubs". The solution mainly includes a frame and a number of iron hooks stacked and hung in the frame, wherein the frame is composed of a first cross bar, a second cross bar, a third cross bar, a fourth cross bar, a support bar, a first vertical bar, a second vertical bar, a third vertical bar, a fourth vertical bar, and a load-bearing bar, and the two ends of the iron hook are respectively hung on the first cross bar and the second cross bar. When stacking, the first layer of bathtubs is placed on the load-bearing rods, and the second to sixth or seventh layers are suspended from the frame by iron hooks. This allows for 6 to 7 layers of stacking within the container's height limit, saving cargo space, increasing cargo capacity, and significantly reducing transportation costs. However, this solution still has the following shortcomings in actual application: First, the iron hooks in this solution only serve to lift the bathtub, and there is no structure to fix the bathtub. When transporting the bathtub to a bumpy road, the bathtub is prone to shaking and colliding with the frame or other stacked bathtubs, causing damage to the bathtub and poor reliability.

[0003] Secondly, since the frame only has an opening at the top, this solution requires the use of a gantry crane for stacking and taking out. Large equipment such as gantry cranes are generally only available at manufacturers. When transported to dealers, they cannot be taken out individually using other lifting equipment such as forklifts. They can only be taken out manually from the top of the frame using a ladder. Since the bathtub is heavy, it is easy to break the bathtub during the taking process, and the worker who takes the bathtub is also likely to fall, posing a great safety risk and the cost of bathtub damage.

[0004] Third, when taking out the bathtubs, one has to take them out one by one from the top layer, which is very inconvenient and inefficient. Moreover, since the bathtubs lack a frame and iron hooks after being taken out, they cannot be stacked and can only be placed one by one on the ground, which takes up a lot of space.

[0005] Fourthly, the number of bathtubs that can be stacked is still limited by the height of the rack. For example, when placing them in a factory warehouse, the height space of the factory warehouse cannot be used to stack more bathtubs, making this solution insufficient to meet the storage needs of larger quantities of bathtubs.

[0006] Therefore, based on the above-mentioned deficiencies, the applicant believes that it is very necessary to redesign the structure of the bathtub stacking packaging structure in order to better meet people's practical application needs. Summary of the Invention

[0007] The object of the present invention is to solve the above-mentioned problems and shortcomings and to provide a bathtub stacking bracket structure, wherein the bathtub stacking bracket structure fixes each bathtub on a first bathtub pallet rack and a second bathtub pallet rack through a plurality of fixing blocks, so that the bathtubs can be prevented from shaking and swinging during transportation and being damaged by bumps and collisions, and the bathtubs will not get loose and fall off when they are lifted. The bathtubs can be lifted and lifted using a gantry crane or other lifting equipment such as a forklift, thereby improving adaptability to different lifting equipment and eliminating the need for manual handling, which greatly reduces labor costs. When taking a bathtub, it can be taken from any layer, and the taking efficiency is very high. When stacking, the stacking quantity can be adjusted at will to solve the storage needs of large quantities of bathtubs, and by providing a bathtub insertion opening, the overall height of multiple bathtubs stacked together can be greatly reduced, so that more bathtubs can be stacked in a container, saving transportation costs.

[0008] The technical solution of the present invention is achieved as follows: A bathtub stacking bracket structure is characterized in that it includes a first bathtub support frame and at least one second bathtub support frame, the first bathtub support frame and the second bathtub support frame are respectively provided with a plurality of fixing blocks arranged around the bathtub and clamping the bathtub, the four corners of the top of the first bathtub support frame and the second bathtub support frame are respectively provided with positioning notches, the four corners of the bottom of the first bathtub support frame and the second bathtub support frame are respectively provided with supporting legs, a first overhead cavity is further formed between the bottom surface of the first bathtub support frame and its four supporting legs, a second overhead cavity is further formed between the bottom surface of the second bathtub support frame and its four supporting legs, and a bathtub insertion opening is further provided in the middle portion of the second bathtub support frame in a vertical manner; the second bathtub support frame is stacked on the first bathtub support frame, and the bottoms of the four supporting legs of the second bathtub support frame are respectively embedded in the four positioning notches of the first bathtub support frame.

[0009] A method for stacking bathtubs using the above-mentioned bathtub stacking bracket structure includes at least two bathtubs and a binding strap, and is characterized by further comprising the following steps: a first step of placing one bathtub with its opening facing downward on a first bathtub support frame, and fixing the bathtub to a center position of the first bathtub support frame by a plurality of fixing blocks arranged around the bathtub, and similarly fixing the other bathtub to a center position of the second bathtub support frame by the plurality of fixing blocks; a second step of placing the first bathtub support frame as the bottom layer, and then placing the second bathtub support frame above the first bathtub support frame, and centrally fitting the bathtub insertion opening of the second bathtub support frame onto the bathtub of the first bathtub support frame so that the bathtub of the first bathtub support frame can pass through the bathtub insertion opening and be placed into the bathtub of the second bathtub support frame, thereby achieving the purpose of stacking the bathtubs and reducing the overall stacking height, and further inserting the bottoms of the four legs of the second bathtub support frame into the four positioning notches of the first bathtub support frame; and a third step of bundling the first bathtub support frame, the second bathtub support frame and the bathtub on the top layer together by the binding strap.

[0010] Beneficial effects of the present invention: The present invention arranges a plurality of fixing blocks around the bathtub and clamps the bathtub, and fixes each bathtub on the first bathtub support frame and the second bathtub support frame respectively. When stacking or taking the bathtubs, the bathtubs can be lifted together with the first bathtub support frame and the second bathtub support frame. This not only prevents the bathtubs from shaking and swinging during transportation and prevents the bathtubs from being damaged by bumps, but also prevents the bathtubs from loosening and falling during the lifting process, thereby greatly improving the reliability of the bathtub stacking, packaging and transportation.

[0011] Moreover, by providing the first overhead cavity and the second overhead cavity, a lifting rope or a forklift's fork can pass through, so that the first bathtub tray frame and the second bathtub tray frame can be lifted and carried by using a gantry crane or other lifting equipment such as a forklift. From manufacturers to dealers, different lifting equipment can be used for lifting, which greatly improves the adaptability of the present invention to different lifting equipment, and does not require manpower for carrying, thereby greatly reducing labor costs.

[0012] At the same time, through the cooperation of the supporting legs and the positioning notches, the stacking assembly stability and separation convenience of the second bathtub support rack and the first bathtub support rack are very good. When taking the bathtub, you can take it from any layer according to the number of bathtubs you need to take, which greatly improves the convenience of taking it and the efficiency of taking it is very high. Moreover, the bathtubs taken can continue to be stacked together in a stacked manner, which greatly reduces the occupied area of the site.

[0013] At the same time, the number of bathtubs stacked can be adjusted at will, and the adjustment is very flexible and convenient. In this way, more bathtubs can be stacked in the factory warehouse to meet the storage needs of large quantities of bathtubs.

[0014] In addition, by providing a bathtub insertion opening, when stacking, the bathtub on the lower layer can be passed through the bathtub insertion opening and placed in the bathtub on the upper layer, so that a non-contact stacking structure is formed between the two adjacent stacked bathtubs. This can greatly reduce the overall height of multiple bathtubs stacked together, so that more bathtubs can be stacked in a container, saving transportation costs.

[0015] Through the above structural design, the bathtub is supported by the first bathtub pallet rack or the second bathtub pallet rack from the manufacturer to the dealer and then from the dealer to the consumer. The bathtub is packaged and fixed once, and the transportation packaging and protection of the bathtub in the entire sales and transportation chain can be achieved. There is no need for repeated packaging, which can greatly save manpower and packaging material costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 and Figure 2As shown, the bathtub stacking bracket structure described in the present invention includes a first bathtub support frame 1 and at least one second bathtub support frame 2. The first bathtub support frame 1 and the second bathtub support frame 2 are respectively provided with a plurality of fixing blocks 3 arranged around the bathtub and clamping the bathtub. The four corners of the top of the first bathtub support frame 1 and the second bathtub support frame 2 are respectively provided with positioning notches 11. The four corners of the bottom of the first bathtub support frame 1 and the second bathtub support frame 2 are respectively provided with supporting legs 12. A first overhead cavity 10 is formed between the bottom surface of the first bathtub support frame 1 and its four supporting legs 12. A second overhead cavity 20 is formed between the bottom surface of the second bathtub support frame 2 and its four supporting legs 12. A bathtub insertion opening 21 is vertically penetrated in the middle of the second bathtub support frame 2. The second bathtub support frame 2 is stacked on the first bathtub support frame 1, and the bottoms of the four supporting legs 12 of the second bathtub support frame 2 are respectively embedded in the four positioning notches 11 of the first bathtub support frame 1. Figure 1 As shown, when placing the bathtub 100 , the bathtub 100 is placed on the center of the first bathtub support frame 1 or the second bathtub support frame 2 with the bathtub 100 open and facing downward.

[0024] In order to further improve the installation structure of the fixed block 3, as shown Figure 2 As shown, the present invention further includes several locking screws 4, with each fixing block 3 being secured to the corresponding first and second bathtub support frames 1 and 2 via these locking screws 4. Locking the fixing blocks 3 via these locking screws 4 facilitates both clamping and removing the bathtub 100. In practice, the fixing blocks 3 can also be secured to the first and second bathtub support frames 1 and 2 via other fixed connection structures, such as rivets, snap-fit mechanisms, or mortise and tenon joints.

[0025] In order to further improve the structure of the first bathtub support frame 1 and the second bathtub support frame 2, so as to make the structure simple and convenient for production and manufacturing, Figure 3 and Figure 4 As shown, the first and second bathtub support frames 1 and 2 each include a frame 13 and a support plate 14 mounted on the top surface of the frame 13. Four positioning notches 11 are located at the four corners of the support plate 14, and four legs 12 are located at the four corners of the frame 13. The bathtub insertion opening 21 is located on the support plate 14 of the second bathtub support frame 2. The support plate 14 provides reliable support for the bathtub. The frame 13 enhances the overall structural strength of the support plate 14, preventing it from bending or deforming, ensuring optimal support for the bathtub.

[0026] In order to make the frame body 13 have the advantages of simple structure, easy implementation and convenient production, such as Figure 3 and Figure 4 As shown, the frame body 13 is a rectangular frame structure formed by connecting two transverse rods 131 and two longitudinal rods 132.

[0027] In order to further improve the overall structural strength of the frame body 13 and make it less prone to deformation and bending, Figure 3 and Figure 4 As shown, a reinforcing rod 133 is further connected between the transverse rod 131 and the longitudinal rod 132 .

[0028] In practical applications, there are two options for the support plate 14 of the first bathtub support frame 1: First, the support plate 14 of the first bathtub support frame 1 can also be provided with a bathtub insertion opening 21, so that the structure of the first bathtub support frame 1 and the second bathtub support frame 2 are consistent. This can make the production of the first bathtub support frame 1 easier and reduce the number of molds required for the bathtub stacking bracket structure. Second, the first bathtub support frame 1 does not have the bathtub insertion opening 21. This not only ensures that the support plate 14 of the first bathtub support frame 1 has very good support and load-bearing performance, but also provides better shielding and protection for the bathtub 100 located at the bottom layer, preventing debris on the ground from scratching the bathtub 100 of the first bathtub support frame 1.

[0029] When the second solution of the support plate 14 of the first bathtub tray frame 1 is adopted, in order to further improve the overall structural strength of the frame body 13, improve the supporting load-bearing performance of the frame body 13 and the support plate 14, and prevent the frame body from deforming and bending, as shown in FIG. Figure 3 As shown, a load-bearing rod 134 is further connected between the two transverse rods 131 of the first bathtub support frame 1 or between the two longitudinal rods 132 of the first bathtub support frame 1. Preferably, the number of the load-bearing rods 134 is two, and the two load-bearing rods 134 are arranged in parallel and spaced apart.

[0030] In order to avoid the surface of the bathtub 100 from being worn when in contact with the first bathtub support frame 1 and the second bathtub support frame 2, and to ensure that the surface of the bathtub 100 is intact during transportation, Figure 5 As shown, a cardboard 141 is further provided on the top surface of the supporting plate 14. This can reduce the hard contact between the bathtub 100 and the first bathtub support plate frame 1 and the second bathtub support plate frame 2, greatly reducing the wear and tear of the bathtub 100.

[0031] Since the bathtub 100 is placed on the first bathtub support frame 1 and the second bathtub support frame 2 with the bathtub 100 open and facing downward, the bathtub 100 will not touch the ground. In order to further reduce the overall height of the bathtubs after being stacked, Figure 2As shown, the height of the legs 12 of the first bathtub support frame 1 is lower than the height of the legs 12 of the second bathtub support frame 2. This can further reduce the overall stacking height and increase the number of bathtubs that can be stacked without affecting the passage of the lifting equipment for lifting.

[0032] In order to prevent the second bathtub support frame 2 and the first bathtub support frame 1 from being loosened and falling during transportation, the present invention further includes a strap 7 for binding the second bathtub support frame 2 and the first bathtub support frame 1 together. Figure 7 As shown, the binding strap 7 is bundled together with the bathtub 100 at the top, so as to further prevent it from coming loose and falling. In actual applications, the binding strap 7 can be a strip that can be used to bundle goods, such as a cloth belt or a steel belt.

[0033] In order to increase the stacking quantity of the present invention, as Figure 6 and Figure 7 As shown, there are two or more second bathtub support racks 2, which are stacked one on top of the other. The bottoms of the four legs 12 of one second bathtub support rack 2 are respectively embedded in the four positioning notches 11 of the other second bathtub support rack 2. Preferably, there are six second bathtub support racks 2, which, when combined with the first bathtub support rack 1 as the bottom layer, can form a seven-layer stack.

[0034] In practice, the transverse bars 131, longitudinal bars 132, reinforcing bars 133, load-bearing bars 134, and legs 12 are each made of 40×40 mm galvanized square tubes, resulting in a stable structure and high compressive strength. The positioning notches 11 are 45×45 mm rectangular notches. The support plate 14 is 15 mm thick. The legs 12 of the first bathtub support frame 1 are 110 mm tall, while the legs 12 of the second bathtub support frame 2 are 220 mm tall.

[0035] In practical applications, the fixing block 3 is a wooden block, which is not easy to scratch the bathtub and has low material cost. Example

[0036] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 As shown, a stacking method using the bathtub stacking bracket structure of the first embodiment includes at least two bathtubs 100 and a strap 7. To achieve the purpose of the stacking method of the present invention, the present invention further includes the following steps: The first step is to place one of the bathtubs 100 with its opening facing downward on the first bathtub support frame 1, and fix the bathtub 100 to the center of the first bathtub support frame 1 by using a plurality of fixing blocks 3 arranged around the bathtub 100. Similarly, place the other bathtub 100 with its opening facing downward on the second bathtub support frame 2, and fix the other bathtub 100 to the center of the second bathtub support frame 2 by using a plurality of fixing blocks 3 arranged around the bathtub 100. Step 2: Place the first bathtub support frame 1 as the bottom layer, then place the second bathtub support frame 2 on top of the first bathtub support frame 1, and center the bathtub insertion opening 21 of the second bathtub support frame 2 over the bathtub 100 of the first bathtub support frame 1, so that the bathtub 100 of the first bathtub support frame 1 can pass through the bathtub insertion opening 21 and be placed inside the bathtub 100 of the second bathtub support frame 2, thereby achieving the purpose of stacking the bathtubs and reducing the overall stacking height. Furthermore, the bottoms of the four legs 12 of the second bathtub support frame 2 are respectively embedded in the four positioning notches 11 of the first bathtub support frame 1; Step 3: Use the straps 7 to tie together the first bathtub support frame 1 , the second bathtub support frame 2 and the bathtub 100 on the uppermost layer.

[0037] In actual use, there are two or more second bathtub trays 2, and the two second bathtub trays 2 are stacked, with the bottoms of the four legs 12 of one second bathtub tray 2 respectively embedded in the four positioning notches 11 of another second bathtub tray 2. Preferably, there are six second bathtub trays 2. When there are six second bathtub trays 2, there are seven bathtubs 100. One bathtub 100 is placed on the first bathtub tray 1, and the remaining six bathtubs 100 are placed on corresponding second bathtub trays 2. The remaining six bathtubs 100 are each secured to the center of the corresponding second bathtub tray 2 using multiple fixing blocks 3 according to the method described in the first step above. After the bathtubs 100 are secured, the six second bathtub trays 2 are stacked on top of each other according to the second step described above. Finally, the first bathtub tray 1, the six second bathtub trays 2, and the bathtub 100 on the top layer are tied together using straps 7 to complete the stacking.

[0038] In order to further improve the installation structure of the fixed block 3, as shown Figure 2As shown, the present invention further includes several locking screws 4, with each fixing block 3 being secured to the corresponding first and second bathtub support frames 1 and 2 via these locking screws 4. Locking the fixing blocks 3 via these locking screws 4 facilitates both clamping and removing the bathtub 100. In practice, the fixing blocks 3 can also be secured to the first and second bathtub support frames 1 and 2 via other fixed connection structures, such as rivets, snap-fit mechanisms, or mortise and tenon joints.
