Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, and in particular to a retractable partition sealing device. Background Technology

[0002] In cold chain transportation, a single compartment temperature can no longer meet the diverse needs of customers for transporting food and other goods. We need a device that can divide the compartment into temperature zones to meet different temperature requirements in cold chain transportation, partition the compartment, and the partition walls must have good thermal insulation performance and be easy to operate.

[0003] Currently, most dual-temperature refrigerated trucks use a fixed sealing structure. However, because this structure is pre-assembled, its proper positioning after installation cannot be guaranteed. This can easily lead to uneven gaps on both sides, excessive or uneven friction causing the partition to flip or become difficult to move, increasing operational complexity. Even when locked, a seal cannot be achieved, affecting insulation performance and safety reliability. Therefore, designing a device that can divide the truck compartment into different temperature zones, is easily movable, and achieves a good seal when locked is a crucial technical problem that needs to be solved in this case. Utility Model Content

[0004] To address the above problems, this utility model provides a retractable partition wall sealing device that is portable, lightweight, efficient, and improves sealing performance after locking.

[0005] The technical solution of this utility model is:

[0006] A retractable partition wall sealing device, comprising:

[0007] The partition wall is detachably and vertically installed inside the compartment; the partition wall is equipped with a detachable and fixed sealing strip around its perimeter.

[0008] The upright plate is fixedly installed on the top surface of the partition wall and is equipped with a rotatable pivot pin;

[0009] The swing arm has a Z-shaped structure, with its middle part fixedly mounted on the pivot pin; the upper and lower ends are respectively provided with tie rods that are hinged to it;

[0010] The telescopic mechanism is provided in pairs, symmetrically arranged on the side of the partition wall, and each is hinged to its corresponding tie rod;

[0011] The telescopic mechanism includes:

[0012] The upper corner rotating panel has its long arm hinged to the pull rod and its short arm hinged to the inner base fixed in the fixed sealing strip.

[0013] Lower corner rotating panel, its long arm end is connected with the lower rod arranged at the bottom of the partition wall, and its short arm end is hinged with the inner base two fixed in the fixed sealing strip;

[0014] Side rod, vertically arranged at the side of the partition wall, the top is hinged with the corner of the upper corner rotating panel, and the bottom is hinged with the corner of the lower corner rotating panel;

[0015] Inner base three, several are provided, and are respectively fixedly arranged in the fixed sealing strips at the side and bottom of the partition wall; the inner base three is hinged with the side rod or the lower rod through the inner small connecting rod;

[0016] Outer base three, several are provided, and are respectively fixedly arranged in the movable sealing strips at the side and bottom of the partition wall, with the same number as the inner base three and corresponding one by one; the outer base three is hinged with the inner small connecting rod through the outer small connecting rod one.

[0017] Specifically, a handle is provided on the rotating pin in a detachable and fixedly connected manner.

[0018] Specifically, an outer base four adapted to the inner base two is provided at the bottom of the side rod;

[0019] The outer base four is hinged with the lower corner rotating panel through the outer small connecting rod two.

[0020] Specifically, the cross sections of the outer base four and the outer base three are respectively in a C-shaped structure.

[0021] Specifically, a locking slider is fixedly connected to the outer base three at the end of the lower rod.

[0022] Specifically, the cross sections of the inner base one, the inner base two and the inner base three are respectively in a C-shaped structure.

[0025] Specifically, the cross section of the upper corner rotating panel is in a V-shaped structure.

[0026] Specifically, the cross section of the lower corner rotating panel is in a V-shaped structure.

[0027] This utility model includes a partition wall, a vertical panel, a rotating arm, and a telescopic mechanism. The telescopic mechanism consists of a pair, symmetrically arranged on the sides of the partition wall and hinged to their corresponding pull rods. The telescopic function of the movable sealing strip is achieved by the simultaneous outward or inward movement of the pair of pull rods. This allows for the division of the cargo compartment, enabling different temperature adjustments within the compartment via different refrigeration units. The partition wall uses the same foaming method as the refrigerated container, providing better insulation and achieving "two temperatures per compartment." It is even possible to have one section unrefrigerated for transporting ordinary goods, effectively saving transportation costs.

[0028] This design employs a multi-link mechanism with simple pin connections between the links. Sealing is achieved by simply rotating a handle on the outside of the partition wall, which moves small push rods with sealing strips on the left, right, and bottom sides outwards. The sealing device extends outwards by 20mm on each side. The extension can also be controlled by changing the length of the small link and the type of sealing strip, making it suitable for different carriage sizes. This significantly reduces or even eliminates issues such as excessive friction between the sealing strip and the carriage panel after installation, leading to difficulties in rotation and movement.

[0050] The following is for reference. Figure 1-10 Describe this utility model;

[0051] A retractable partition wall sealing device, comprising:

[0052] The partition wall 100 is detachably and vertically installed inside the compartment; the partition wall is provided with a detachable and fixed sealing strip 110 around its perimeter.

[0053] A vertical plate 200 is fixedly installed on the top surface of the partition wall 100 and is provided with a rotatable pivot pin 210; the pivot pin 210 is provided with a detachable and fixedly connected handle 800. In this case, the handle 500 is located on one side of the pivot pin 210 and the rotating arm 300 is located on the other side of the pivot pin 210.

[0054] The swing arm 300 has a Z-shaped structure, with its middle part fixedly mounted on the pivot pin 210; the upper and lower ends are respectively provided with tie rods 310 that are hinged to it;

[0055] The telescopic mechanism 400 is provided in pairs, symmetrically arranged on the side of the partition wall 100, and respectively hinged to its corresponding tie rod 310;

[0056] The telescopic mechanism includes:

[0057] The upper corner rotating panel 410 has its long arm end hinged to the pull rod 310, and its short arm end hinged to the inner base 510 fixed in the fixed sealing strip 110.

[0058] The lower corner rotating panel 420 has its long arm end connected to the lower rod 620 set at the bottom of the partition wall 100, and its short arm end hinged to the inner base 520 fixed in the fixed sealing strip 110.

[0059] The upper corner rotating panel 410 and the lower corner rotating panel 420 in this case have V-shaped cross sections.

[0060] Side rod 610 is vertically installed on the side of the partition wall 100, with its top end hinged to the corner of the upper corner rotating panel 410 and its bottom end hinged to the corner of the lower corner rotating panel 420.

[0061] In this case, the bottom of the side rod 610 is provided with an outer base 4 550 that is compatible with the inner base 2 520; the outer base 4 550 is hinged to the lower corner rotating panel 420 through the outer small connecting rod 2 551.

[0062] A locking slider 700 is fixedly connected to the outer base three 540 at the end of the lower rod 620 (the end near the middle position of the partition wall 100). The locking slider 700 is telescopically moved up and down within the movable sealing strip 120. In this case, the locking slider 700 is made of rubber material. As the outer base three 540 is stretched downward, it compresses and locks with the floor inside the carriage, achieving a tight connection with the refrigerated carriage.

[0063] There are several inner bases three (530), which are respectively fixedly arranged within the fixed sealing strips (110) on the side and bottom of the partition wall (100); the inner bases three (530) are hinged to the side rod (610) or the lower rod (620) through the inner side small connecting rods (531); specifically, in this case, there are a pair of inner side small connecting rods (531), one end of which is hinged to the inner base three (530), and the other end is hinged to the side rod (610);

[0064] There are several outer bases three (540), which are respectively fixedly arranged within the movable sealing strips (120) on the side and bottom of the partition wall (100), and have the same number as the inner bases three (530) and correspond to each other one by one; the outer bases three (540) are hinged to the inner side small connecting rods (531) through the outer side small connecting rods one (541).

[0065] In this case, the movable sealing strip 120 is arranged outside the fixed sealing strip, and the sealing or disassembly function is achieved through the expansion and contraction of the movable sealing strip 120.

[0066] The cross-sections of the inner base one 510, the inner base two 520, the inner base three 530, the outer base four 550 and the outer base three 540 are respectively in a U-shaped structure.

[0067] In this case, the fixed sealing strip 110 uses an H-shaped sealing strip, and the movable sealing strip 120 uses a D-shaped blade sealing strip.

[0068] As Figure 10 shown, the movable sealing strip 120 in the top area of the partition wall 100 is fixedly arranged on the top outer base; the top fixed sealing strip is directly bonded with hard PVC and then fixed to the partition wall 100 with screws. When the sealing strip is molded, the hardness of the area with cross-section lines is greater than that of the top D-shaped blade sealing strip (the area without cross-section lines); a fixed connection method is adopted between the top fixed sealing strip and the movable sealing strip 120, and the whole device mainly realizes the functions of device disassembly and sealing through the adjustment of the side and bottom.

[0069] The usage method of this case is:

[0070] As Figure 6 shown, by rotating the handle 800 to the right, the rotating pin 210 on the vertical plate 200 is rotated, thereby driving the upper pair of pull rods 310 to displace respectively towards the middle of the partition wall 100, and the pull rods 310 pull the upper corner rotating panel 410, so as to Figure 6 Taking the left-side telescopic mechanism as an example, the upper corner rotating panel 410 pulls the side rod 610 to move upward and to the left. The inner bases one, two, and three are completely fixed in the fixed sealing strips at the edge of the partition wall and will not move. The inner small connecting rod 531 will only rotate around the hinge hole on the inner base three 530. Then the side rod 610 pulls the inner small connecting rod 531 upward and straightens it. The outer small connecting rod one 541 and the outer small connecting rod two 551 are straightened in the same way, while the outer base three 540 and the outer base four 550 only move horizontally outward. The side rod 610 will pull the lower corner rotating panel 420 to rotate, thereby pulling the lower rod 620 to move to the left, causing the lower inner small connecting rod 531 and the outer small connecting rod one 541 to straighten downward. The locking slider 700 is locked with the compression of the floor inside the carriage as the corresponding inner and outer small connecting rods are stretched, thus completing the straightening process. The movement of the right-side mechanism is the same as the left-side mechanism.

[0071] This invention employs a multi-link mechanism with simple pin connections between the links. Sealing is achieved by simply rotating the handle on the outside of the partition wall, which pushes the small push rods with sealing strips on the left, right, and bottom sides outwards. The sealing device extends outwards by 20mm on each side. The extension can also be controlled by changing the length of the small link and the type of sealing strip, making it suitable for different carriage sizes. This significantly reduces or even eliminates the problem of excessive friction between the sealing strip and the carriage panel after installation, making it difficult to rotate or move.

[0073] (1) The accompanying drawings of the embodiments disclosed in this case only involve the structures involved in the embodiments disclosed in this case. Other structures can refer to the general design.

[0074] (2) Where there is no conflict, the embodiments and features disclosed in this case can be combined with each other to obtain new embodiments;

[0075] The above are merely specific embodiments disclosed in this case, but the scope of protection of this disclosure is not limited thereto. The scope of protection disclosed in this case shall be determined by the scope of protection of the claims.
