Description
Technical Field
[0001] The utility model relates to the technical field of storage boxes, and more specifically to a box cover slow-closing device and a box. Background Art
[0002] Boxes are very practical tools that are used to store a variety of items. Whether it is clothes and books in daily life, or documents that need to be sorted and filed in the office, boxes can provide a safe and tidy storage space. For those large boxes, since the lid is relatively heavy, there is a potential safety hazard during use: if the lid is accidentally closed, it may injure the user's hand. This situation usually occurs when the user accidentally loses control of the lid when carrying or sorting items, resulting in unexpected injuries.
[0003] In existing technical applications, in order to slow down the closing speed of the box lid, a damping strut device is usually used. This damping strut can generate a certain blocking force during the closing process of the box lid through its internal hydraulic or pneumatic mechanism, thereby achieving the effect of slowing down the closing speed of the box lid. However, this design has some obvious disadvantages. First, the damping strut will take up valuable space inside the box, which is a big problem for boxes with limited space. Secondly, the manufacturing and installation costs of the damping strut are relatively high, which not only increases the overall production cost, but also may affect the market competitiveness of the product. Therefore, although the damping strut has a certain effect in slowing down the closing speed of the box lid, its disadvantages of occupying space and high cost have made people look for more efficient and economical alternatives. Utility Model Content
[0004] In view of the technical problem in the prior art that the box cover is easily hit by the hand when it is accidentally closed, this solution provides a box cover slow closing device and a box. In this solution, a buffer component is arranged at the connection between the box cover and the box body to prevent the box from being accidentally closed, which not only solves the prior art but also has the advantages of simple structure and low cost.
[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:
[0006] A box cover slow closing device, comprising
[0007] A first buckle is fixed to the side of the box cover;
[0008] A second buckle is fixed to the side of the box body and is arranged opposite to the position of the first buckle, and has a buffer component, and a first buffer zone and a second buffer zone are formed between the buffer component and the box body;
[0009] A collar, one end of the collar is rotatably connected to the first buckle, and the other end is sleeved in the buffer member; when the collar enters the first buffer zone from the second buffer zone, a blocking force that blocks the closing of the lid is generated.
[0010] The first buckle is installed on the side of the lid, and the second buckle is fixed to the box body. The two are connected by a hinge. When the lid is fully opened, one end of the collar will stay in the second buffer zone. As the lid closes, the first buckle drives one end of the collar to rotate, causing the other end of the collar to move from the second buffer zone into the first buffer zone. The blocking force generated during the movement of the collar is transmitted to the lid, thereby preventing it from closing further. Only by applying sufficient pressure to overcome the blocking force of the collar can the lid be fully closed. This design effectively prevents the lid from closing quickly by accident, improving the safety of use. At the same time, due to its simple structure, it is convenient for production and assembly, reducing costs and enhancing the market competitiveness of the product. In addition, this device hardly occupies space when not in use, maintaining the compact design of the box and meeting the user's demand for maximizing space utilization.
[0011] In a lid slow-closing device provided in this application, further, the buffer member includes a first protrusion provided on the second buckle, and an inner space is formed between the first protrusion and the corresponding box body. The inner space formed by the first protrusion can provide a displacement space for one end of the collar and can also limit the moving distance of the collar.
[0012] In a lid slow-closing device provided in this application, further, the buffer member includes a second protrusion fixedly connected to the box body, the second protrusion is located in the inner space, and divides the inner space into the first buffer zone and the second buffer zone. The second protrusion can divide the inner space into the first buffer zone and the second buffer zone. When the lid is closed, the collar must pass over the second protrusion from the second buffer zone and enter the first buffer zone before the lid can complete the closing action. There is a gap between the second protrusion and the inner wall of the first protrusion, and this gap is smaller than the diameter of the collar. When the collar passes through the gap, it squeezes the inner wall of the first protrusion, causing the first protrusion to deform, and the first protrusion generates a blocking force due to the deformation. This blocking force is greater than the force exerted on the first buckle by the accidental closing of the lid, so it can prevent the lid from closing accidentally. If the lid needs to be fully closed, the operator needs to apply a greater force to the lid to overcome the blocking force, expand the gap and make the collar pass through smoothly, and finally make the lid close smoothly.
[0013] In a lid slow - closing device provided by the present application, further, the buffer member includes a protrusion provided on the first bump. The protrusion extends towards the box body and divides the inner space into a first buffer section and a second buffer section. The function of the protrusion is the same as that of the second bump, that is, it divides the inner space into a first buffer section and a second buffer section and forms a gap between the protrusion and the box body. This gap is also smaller than the diameter of the collar. When the collar passes through the gap, it squeezes the inner wall of the first bump through the protrusion, causing the first bump to deform. Due to the deformation, the first bump generates a blocking force. This blocking force is greater than the force exerted on the first buckle when the lid accidentally closes, so it can prevent the lid from closing accidentally. If the lid needs to be completely closed, the operator needs to apply a greater force to the lid to make the collar overcome the blocking force, expand the gap and enable the collar to pass through smoothly, and finally make the lid close smoothly.
[0014] In a lid slow - closing device provided by the present application, further, the collar is of a rectangular structure and includes a first rod and a second rod. The first rod is rotatably connected to the first buckle, the second rod is sleeved in the buffer member, and the two ends of the first rod and the second rod are fixedly connected by a third rod. The collar is of a rectangular structure. The first rod can meet its rotational requirement on the first buckle, and the second rod can meet the movement requirement in the buffer member. The third rod can transmit the lid - closing action of the lid to the second rod through the first rod, and the blocking force received by the second rod is transmitted to the first rod through the third rod, and then the lid is blocked from closing accidentally through the first buckle.
[0015] In a lid slow - closing device provided by the present application, further, a third bump is provided on the first buckle, and the first rod is rotatably connected within the third bump. The function of the third bump is to enhance the stability of the first rod and prevent excessive swing when transmitting the blocking force.
[0016] In a lid slow - closing device provided by the present application, further, a first notch is provided on the lid, and the first buckle is fixed within the first notch; a second notch is provided on the box body, and the second buckle is fixed within the second notch. The first notch and the second notch can completely accommodate the first buckle and the second buckle, reducing the risk of damage to the first buckle and the second buckle due to collision.
[0017] A box includes a box body and a lid, and the lid slow - closing device as described above is connected between the box body and the lid.
[0018] In a lid slow - closing device provided by the present application, further, there are placed in the box body no less than two identical or different built - in boxes. The built - in boxes can further allocate the space of the box body, enabling the box body to load items of specific shapes. Two identical or two different built - in boxes can prevent the items loaded in the box body from colliding and causing damage to the loaded items.
[0019] In a box provided by the present application, further, a positioning groove is opened at the bottom of the box body, and a positioning block matching the positioning groove is provided on one side of the contact surface between the built - in box and the bottom of the box body. The positioning block is engaged in the positioning groove. The cooperation of the positioning groove and the positioning block can quickly position the built - in box, effectively reducing the time consumption during the loading and unloading processes and improving the packing efficiency. In addition, the setting of the positioning groove and the positioning block can also prevent the built - in box from sliding and tipping over during transportation, ensuring the safe and stable storage of items.
[0020] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0021] In the lid slow - closing device of the present utility model, the first buckle is installed on the side of the lid, and the second buckle is fixed to the box body. The two are connected by a hinge. When the lid is fully opened, one end of the collar stays in the second buffer zone. As the lid closes, the first buckle drives one end of the collar to rotate, causing the other end of the collar to move from the second buffer zone into the first buffer zone. The resistance generated during the movement of the collar is transmitted to the lid, thereby preventing it from closing further. Only by applying sufficient pressure to make the collar overcome the resistance can the lid be completely closed. This design effectively prevents the lid from closing quickly by accident, improving the use safety. At the same time, due to the simple structure, it is convenient for production and assembly, reducing the cost and enhancing the market competitiveness of the product. In addition, the device hardly occupies space when not in use, maintaining the compact design of the box and meeting the user's demand for maximizing space utilization.

[0039] As shown Figure 1-3 in the figure, a slow-closing device for a box cover 100 includes a first buckle 300 fixed to the side of the box cover 100; a second buckle 400 fixed to the side of the box body 200 and arranged opposite to the position of the first buckle 300, which has a buffer member 500. A first buffer interval 511 and a second buffer interval 512 are formed between the buffer member 500 and the box body 200; a collar 600, one end of the collar 600 is rotatably connected to the first buckle 300, and the other end is sleeved in the buffer member 500; when the collar 600 enters the first buffer interval 511 from the second buffer interval 512, a blocking force that blocks the closing of the box cover 100 is generated. The first buckle 300 is installed on the side of the box cover 100, while the second buckle 400 is fixed to the box body 200. The two are connected by a hinge. When the box cover 100 is fully opened, one end of the collar 600 will stay in the second buffer area. As the box cover 100 closes, the first buckle 300 drives one end of the collar 600 to rotate, causing the other end of the collar 600 to move from the second buffer area into the first buffer area. The blocking force generated during the movement of the collar 600 is transmitted to the box cover 100, thereby preventing it from closing further. Only by applying sufficient pressure to make the collar 600 overcome the blocking force can the box cover 100 be fully closed. This design effectively prevents the box cover 100 from closing quickly by accident, improving the use safety. At the same time, due to the simple structure, it is convenient for production and assembly, reducing the cost and enhancing the market competitiveness of the product. In addition, this device hardly occupies space when not in use, maintaining the compact design of the box and meeting the user's demand for maximizing space utilization.
[0040] As shown Figure 2-3As shown, the buffer member 500 includes a first protrusion 530 provided on the second buckle 400. An inner space 510 is formed between the first protrusion 530 and the corresponding box body 200. The inner space 510 formed by the first protrusion 530 can provide a displacement space for one end of the collar 600 and can also limit the moving distance of the collar 600. The buffer member 500 includes a second protrusion 540 fixedly connected to the box body 200. The second protrusion 540 is located in the inner space 510 and divides the inner space 510 into a first buffer section 511 and a second buffer section 512. The second protrusion 540 can divide the inner space 510 into the first buffer section 511 and the second buffer section 512. When the lid 100 is closed, the collar 600 must pass from the second buffer section 512 over the second protrusion 540 and enter the first buffer section 511 before the lid 100 can complete the closing action. There is a gap 560 between the inner wall of the second protrusion 540 and the first protrusion 530, and this gap 560 is smaller than the diameter of the collar 600. When the collar 600 passes through the gap 560, it squeezes the inner wall of the first protrusion 530, causing the first protrusion 530 to deform, and the first protrusion 530 generates a blocking force due to the deformation. This blocking force is greater than the force exerted on the first buckle 300 by the accidental closing of the lid 100, so it can prevent the lid 100 from closing accidentally. If the lid 100 needs to be completely closed, the operator needs to apply a greater force to the lid 100 to make the collar 600 overcome the blocking force, expand the gap 560 and allow the collar 600 to pass smoothly, and finally make the lid 100 close smoothly.
[0041] As Figure 4 shown, the collar 600 has a rectangular structure and includes a first rod body 610 and a second rod body 620. The first rod body 610 is rotatably connected to the first buckle 300, the second rod body 620 is sleeved in the buffer member 500, and both ends of the first rod body 610 and the second rod body 620 are fixedly connected by a third rod body 630. The collar 600 has a rectangular structure. The first rod body 610 can meet its rotational requirements on the first buckle 300, and the second rod body 620 can meet the moving requirements within the buffer member 500. The third rod body 630 can transmit the closing action of the lid 100 from the first rod to the second rod body 620, and the blocking force received by the second rod body 620 is transmitted to the first rod body 610 through the third rod body 630, and then the first buckle 300 blocks the accidental closing of the lid 100.
[0042] As Figure 2 shown, the first buckle 300 is provided with a third protrusion 310, and the first rod body 610 is rotatably connected within the third protrusion 310. The function of the third protrusion 310 is to enhance the stability of the first rod body 610 and prevent excessive swinging when transmitting the blocking force.
[0043] As Figure 5As shown in the figure, a first notch 110 is provided on the box cover 100, and a first buckle 300 is fixed in the first notch 110; a second notch 210 is provided on the box body 200, and a second buckle 400 is fixed in the second notch 210. The first notch 110 and the second notch 210 can completely accommodate the first buckle 300 and the second buckle 400, reducing the risk of damage to the first buckle 300 and the second buckle 400 due to collision. Embodiment 2
[0044] As Figure 6 shown in the figure, in this embodiment, the buffer member 500 includes a protruding portion 550 provided on the first convex block 530. The protruding portion 550 extends towards the box body 200 and divides the inner space 510 into a first buffer section 511 and a second buffer section 512. The function of the protruding portion 550 is the same as that of the second convex block 540, that is, it divides the inner space 510 into a first buffer section 511 and a second buffer section 512 and forms a gap 560 between the protruding portion 550 and the box body 200. The gap 560 is also smaller than the diameter of the collar 600. When the collar 600 passes through the gap 560, the inner wall of the first convex block 530 is squeezed by the protruding portion 550, causing the first convex block 530 to deform, and the first convex block 530 generates a blocking force due to the deformation. This blocking force is greater than the force exerted on the first buckle 300 when the box cover 100 is accidentally closed, so it can prevent the box cover 100 from being accidentally closed. If the box cover 100 needs to be completely closed, the operator needs to apply a greater force to the box cover 100 to make the collar 600 overcome the blocking force, expand the gap 560 and allow the collar 600 to pass through smoothly, and finally make the box cover 100 close smoothly. Embodiment 3
[0045] As Figure 7 shown in the figure, this embodiment provides a box, including a box body 200 and a box cover 100, and a slow-closing device for the box cover 100 is connected between the box body 200 and the box cover 100. At least two identical or different built-in boxes 700 are placed in the box body 200. The built-in boxes 700 can further allocate the space of the box body 200, enabling the box body 200 to load items of a specific shape. Two identical or two different built-in boxes 700 can prevent the items loaded in the box body 200 from colliding and causing damage to the loaded items.
[0046] A positioning groove 710 is opened at the bottom of the box body 200. A positioning block 720 matching the positioning groove 710 is provided on one side of the contact surface between the built-in box 700 and the bottom of the box body 200. The positioning block 720 is engaged in the positioning groove 710. The cooperation of the positioning groove 710 and the positioning block 720 can quickly position the built-in box 700, effectively reducing the time consumption during the loading and unloading processes and improving the packing efficiency. In addition, the setting of the positioning groove 710 and the positioning block 720 can also prevent the built-in box 700 from sliding and tipping over during transportation, ensuring the safe and stable storage of items.
[0047] The above has schematically described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by this and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
