Description

Technical Field

[0001] The present invention relates to the technical field of transfer boxes, and particularly to a high-strength transfer box based on composite reinforcing materials. Background Art

[0002] The transfer box is also called a transfer frame. For the convenience of turnover, in most cases, it is made of plastic and is used in logistics, warehousing or production links. It is also called a logistics box. The standard plastic turnover box is made of polypropylene or high-density polyethylene. It is light to use, corrosion-resistant, has relatively high strength and is not easy to deform. Reinforcing ribs are also provided on its four outer wall surfaces and bottom surface to further improve its strength and anti-deformation ability. In order to facilitate the forklift to quickly transfer it, two support seats are also provided at the bottom of the box. A forklift hole is formed between the two support seats to facilitate the insertion of the lifting rod of the forklift to quickly transfer it.

[0003] When transferring the transfer box through the forklift lifting rod, the bumps generated when the forklift travels will affect the products in the box. For example, plastic or glassware will collide with each other due to the bumps during transfer. There is a large activity space between the products and the box wall when the products are placed in the transfer box. The mutual collision during the transfer of the lifting transfer box will affect the product quality. Even when the transfer box is used on the ground, it lacks a transfer structure and is difficult to transfer manually. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a high-strength transfer box based on composite reinforcing materials, including a box body. A cushion is provided on the inner cavity wall of the box body. A notch is opened on the box body. A first hinge seat corresponding outside the notch is installed on the box wall of the box body. A holding plate is provided in the notch. One end of the holding plate is hinged on the first hinge seat. The other end of the holding plate rotates in the notch and is connected to the cushion. A second hinge seat is provided on the box body. A pressing arm is hinged on the second hinge seat. Two support seats are fixed at the bottom of the box body. A forklift space is formed between the two support seats. A through groove is opened on the pressing arm. A positioning rod assembly is fixed on the box body. The positioning rod assembly extends into the through groove to limit one end of the pressing arm from moving upward to abut against the holding plate, and at the same time to limit the other end of the pressing arm from moving downward to reach the bottom side of the forklift space.

[0005] As a further preferred option, the positioning rod assembly includes a sleeve welded on the first hinge seat. The sleeve extends outward through the through groove to the outside of the pressing arm and is provided with internal threads. The positioning rod assembly further includes a bolt connected to the sleeve through the internal threads. The bolt head part is restricted outside the through groove of the pressing arm.

[0006] As a further preference, the first hinge seat is located outside the notch and bends upward. One end of the holding plate that rotates within the notch bends towards the cushion and is connected to the upper position of the side wall of the cushion. The bottom end of the cushion extends downward along the inner side of the cavity wall of the box body and is hinged to the bottom of the cavity of the box body.

[0007] As a further preference, there are two groups of notches, front and back. The front group is symmetrically arranged on the front side wall of the box body, and the back group is symmetrically arranged on the back side wall of the box body. There are four holding plates, and each holding plate rotates within one notch. There are two cushions that are symmetrically arranged front and back. The two front holding plates are jointly connected to the front cushion, and the two back holding plates are jointly connected to the back cushion. One first hinge seat is provided on the box body corresponding to the outside of each notch, and each holding plate is correspondingly hinged to one first hinge seat. One second hinge seat is provided on the box body corresponding to the outside of each first hinge seat, and one pressing arm is correspondingly connected to each second hinge seat. One pressing wheel that abuts against one holding plate is correspondingly arranged at the top end of each pressing arm.

[0008] As a further preference, the pressing wheel is a grooved wheel, and its wheel groove rolls on the holding plate.

[0009] As a further preference, a horizontal toggle rod is jointly connected between the bottom ends of the left and right pressing arms on the same side. When the toggle rod rotates upward, it drives the two pressing arms on the same side to press the two pressing wheels on the same side against the two holding plates on the same side. When the toggle rod rotates downward, it drives the two pressing arms on the same side to separate the two pressing wheels on the same side from the two holding plates on the same side. A connecting rod structure is provided between the front and back toggle rods, so that the front and back toggle rods can move synchronously. At the same time as their synchronous movement, the four pressing arms are used to control the four pressing wheels to simultaneously abut against the four holding plates or simultaneously disengage from the four holding plates. A first through hole is provided on the toggle rod, and a second through hole is provided on the bottom edge of the box body. When the toggle rod rotates to the bottom of the box body, the first through hole coincides with the bottom of the second through hole. The first through hole is a threaded hole, and the threaded hole matches the bolt.

[0010] As a further preference, the holding plate bends inward towards the cushion, and the inner surface of the cushion bulges inward.

[0011] As a further preference, a hollowed-out grid is provided upward from the bottom surface of the support seat.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] 1. When the forklift transfers the transfer box, as the lifting rod is lifted to the bottom surface of the box, the lifting rod will eventually deflect the two pressure arms toward the holding plate, and the two pressure wheels will be pressed against the two holding plates on the same side, so that the two front holding plates will be deflected inward along the notch, and the deflection action will be used to hold the pad on the front wall of the box on the front side of the product. When the front lifting rod performs the above action, it will also drive the rear lifting rod to move synchronously through the connecting rod structure, and the rear lifting rod will drive the rear left and right pressure arms to deflect toward the rear left and right holding plates. The two pressure wheels at the rear are pressed against the two holding plates at the rear, and the deflection of the two holding plates at the rear causes the pads on the rear wall of the box to hold the rear side of the product. That is, when the forklift transfers the box, in addition to inserting the lifting rod into the bottom of the box, the two front and rear pads will be triggered to hold the product tightly when it drags the bottom. Even if the forklift is bumped during travel, the bump will be transmitted to the lifting rod, and then to the box. The product in the box is flexibly held tightly, so the destructiveness of the product is greatly reduced, and safe production is achieved. It should be further explained that the products are not limited to multiple products arranged in the box. Since these products are arranged together, only two pads are needed to hold their outermost layers from the front and back sides to reduce shaking, and can cope with bumps during transfer, which can also play a protective role.

[0014] 2. Pull the lever downward, the pressure arm rotates downward due to the loss of restriction on the outside, the lever moves to the bottom of the box, and the first through hole overlaps the bottom of the second through hole, the disassembled bolt passes through the second through hole and connects to the first through hole, so that the lever is restricted to the bottom of the box, the lever restricts the pressure arm, and the pressure arm restricts the pressure wheel to the ground, which is convenient for manual transfer of the transfer box when operating in the workshop. The pressure wheel not only plays the role of driving the holding plate to hold the action, but also plays the role of assisting the rapid transfer of the transfer box after it falls to the ground, and is more flexible to use.

Specific embodiments

[0025] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments.

[0026] In one embodiment, as Figures 1 - 9 shown:

[0027] This embodiment provides a high-strength transfer box based on composite reinforcing materials, including a box body 1. A cushion 2 is provided on the inner cavity wall of the box body 1. A notch 3 is opened on the box body 1. A first hinge seat 4 corresponding outside the notch 3 is installed on the box wall of the box body 1. A clamping plate 5 is provided in the notch 3. One end of the clamping plate 5 is connected to the first hinge seat 4 in a rotating manner. The other end of the clamping plate 5 rotates in the notch 3 and is connected to the cushion 2. A second hinge seat 6 is provided on the box body 1. A pressing arm 7 is connected to the second hinge seat 6 in a rotating manner. Two support seats 9 are fixed at the bottom of the box body 1. A forklift space 8 is formed between the two support seats 9. A through slot 11 is opened on the pressing arm 7. A positioning rod assembly 12 is fixed on the box body 1. The positioning rod assembly 12 extends into the through slot 11 to limit one end of the pressing arm 7 from pressing upward against the clamping plate 5 and at the same time to limit the other end of the pressing arm 7 from reaching the bottom side of the forklift space 8.

[0028] The positioning rod assembly 12 includes a sleeve 16 welded to the first hinge seat 4. The sleeve 16 extends outward through the through slot 11 to the outside of the pressing arm 7 and is provided with internal threads. The positioning rod assembly 12 further includes a bolt 17 connected to the sleeve 16 through the internal threads. The cap portion of the bolt 17 is restricted outside the through slot 11 of the pressing arm 7.

[0029] The first hinge seat 4 is located outside the notch 3 and bends upward. One end of the clamping plate 5 that rotates within the notch 3 bends towards the direction of the cushion 2 and is connected to the upper position of the side wall of the cushion 2. The bottom end of the cushion 2 extends downward along the inner side of the cavity wall of the box body 1 and is hinged to the bottom of the cavity of the box body 1.

[0030] The notches 3 are in two groups, front and back. The front group is symmetrically arranged on the front side wall of the box body 1, and the back group is symmetrically arranged on the back side wall of the box body 1. There are four clamping plates 5, and each clamping plate 5 rotates within one notch 3. There are two cushions 2 that are symmetrically arranged, front and back. The two front clamping plates 5 are jointly connected to a front cushion 2, and the two back clamping plates 5 are jointly connected to a back cushion 2. A first hinge seat 4 is provided on the box body 1 corresponding to the outside of each notch 3. Each clamping plate 5 is correspondingly hinged to a first hinge seat 4. A second hinge seat 6 is provided on the box body 1 corresponding to the outside of each first hinge seat 4. A pressing arm 7 is correspondingly connected to each second hinge seat 6. A pressing wheel 13 that abuts against one clamping plate 5 is correspondingly provided at the top end of each pressing arm 7.

[0031] A horizontal toggle lever 14 is jointly connected between the bottom ends of the left and right pressing arms 7 on the same side. When the toggle lever 14 rotates upward, it drives the two pressing arms 7 on the same side to press the two pressing wheels 13 on the same side against the two clamping plates 5 on the same side. When the toggle lever 14 rotates downward, it drives the two pressing arms 7 on the same side to separate the two pressing wheels 13 on the same side from the clamping plates 5 on the same side. A link structure 15 is provided between the front and back toggle levers 14, enabling the front and back toggle levers 14 to act synchronously. And while they act synchronously, the four pressing arms 7 control the four pressing wheels 13 to simultaneously contact the four clamping plates 5 or simultaneously disengage from the four clamping plates 5. A first through hole 18 is provided on the toggle lever 14, and a second through hole 19 is provided on the bottom edge of the box body 1. When the toggle lever 14 rotates to the bottom of the box body 1, the first through hole 18 coincides with the bottom of the second through hole 19. The first through hole 18 is a threaded hole, and the threaded hole matches the bolt 17.

[0032] Principle of use and technical effect: Place the product in the box body 1. The product is clamped between the left and right cushion pads 2 to play a protective role. The two support seats 9 rest on the ground, forming a forklift space 8 between them and the ground. This forklift space 8 is used to place the forklift lifting rod. The forklift inserts the lifting rod along the bottom of the front-side tilting rod 14 into the forklift space 8. At this time, the tilting rod 14 is located on the top surface of the lifting rod. The forklift drives the lifting rod to rise. The lifting rod provides a lifting force to the tilting rod 14, causing the left and right pressure arms 7 on the same side of the tilting rod 14 to deflect around the second hinge seat 6 towards the holding plate 5. As the lifting rod is lifted to the bottom surface of the box body 1, the tilting rod 14 will finally continue to deflect the two pressure arms 7 towards the holding plate 5 and press the two pressure wheels 13 against the two holding plates 5 on the same side, causing the two front holding plates 5 to deflect inwards along the notch 3 and using the deflection action to make the cushion pads 2 on the front-side cavity wall of the box body 1 hold on the front side of the product. When the front tilting rod 14 performs the above actions, it will also drive the rear tilting rod 14 to move synchronously through the link structure 15, and the rear tilting rod 14 will drive the left and right pressure arms 7 on the rear side to deflect towards the left and right holding plates 5 on the rear side, so that the two rear pressure wheels 13 press on the two rear holding plates 5. The deflection action of the two rear holding plates 5 makes the cushion pads 2 on the rear-side cavity wall of the box body 1 hold on the rear side of the product. That is, when the forklift transfers the box body 1, in addition to inserting the lifting rod into the bottom of the box, during its bottom-dragging action, it will also trigger the front and rear cushion pads 2 to tightly hold the product. Even if the forklift bumps during travel, the bumps will be transmitted to the lifting rod and then to the box body 1. The products in the box body 1 are flexibly held, so the damage to the products is greatly reduced, achieving safe production. It should be further noted that the products are not limited to multiple products arranged in the box body 1. Since these products are arranged together, only the two cushion pads 2 need to hold them on the outermost layer from the front and rear sides to reduce shaking and can cope with bumps during transfer, and can also play a protective role.

[0033] In addition, a positioning rod assembly 12 for positioning after the pressure arm 7 rotates up and down is also provided. By the above method, when transferring the transfer box from a low position point (such as the ground) to a high position point (such as a transfer vehicle, a shelf) by a forklift, the tilting rod 14 is pulled up, causing the pressure arm 7 to deflect upwards, so that the through groove 11 on the pressure arm 7 is sleeved on the sleeve 16. The bolt 17 is connected to the outer end of the sleeve 16, and the bolt head part is restricted on the pressure arm 7 to position the pressure arm 7. The pressure arm 7 restricts the pressure wheel 13 on the holding plate 5. When the lifting rod of the forklift enters and performs the lifting action, it can trigger the tilting rod 14 to rotate upwards, and through the above series of driving relationships, the two cushion pads 2 hold on the product. The bolt 17 can also be removed from the sleeve 16. At this time, the tilting rod 14 is pulled downwards, and the pressure arm 7 rotates downwards due to the loss of restriction on the outside (as Figure 9As shown in the figure, at this time, the lever 14 rotates to the bottom of the box, aligns the first through hole 18 with the bottom of the second through hole 19, passes the removed bolt 17 through the second through hole 19 and connects it to the first through hole 18, restricting the lever 14 on the bottom of the box. The lever 14 presses the pressing arm 7, and the pressing arm 7 restricts the pressing wheel 13 on the ground. During operation in the workshop, it is convenient for manual workers to quickly transfer the transfer box. The pressing wheel 13 not only plays a role in driving the holding plate 5 to perform the holding action, but also serves the purpose of assisting in the quick transfer of the transfer box after it lands, making the use more flexible.

[0034] As shown in Figure 1, Figure 3 As shown in the figure, the holding plate 5 bends inward towards the direction of the cushion 2. The inner surface of the cushion 2 bulges inward. When the holding plate 5 drives the cushion 2 to deflect inward and uses the cushion 2 to hold the product tightly, the bulge will also provide a greater holding force to the product, further preventing the product from shaking and further preventing the products from colliding with each other, providing better protection. When a large number of products are arranged in the box, when the cushion 2 uses the inner surface of the bulge to hold the outermost layer of products, it will use the protruding part to form a better wrapping force on the products, and the holding force is more concentrated on the products in the middle area of the outer layer, forcing these products to push the products in the areas on both sides of them towards the left and right ends of the box wall, further improving the stability.

[0035] As Figure 6 As shown in the figure, a hollowed-out grid is provided upward from the bottom surface of the support base 9. Although the support base 9 is provided, the support base 9 is light in weight and has high strength through the grid design.

[0036] As Figure 4 , Figure 5 As shown in the figure, the pressing wheel 13 is a grooved wheel, and its wheel groove rolls on the holding plate 5, using the rolling property of the pressing wheel 13 to provide pressure to the holding plate 5, and when the grooved-wheel type pressing wheel 13 cooperates with the holding plate 5, the stability is improved.
