[0002] A refrigerated truck is a closed van transport truck used to maintain the temperature of frozen or fresh goods. A refrigerated truck is a special refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment.

[0003] The refrigerated truck consists of a special chassis, an insulated refrigerated compartment, a refrigeration unit, and a temperature recorder inside the compartment. The insulated refrigerated compartment is equipped with two rear doors, which can be opened and closed to place and remove goods from the compartment.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the rear door panel is connected to the refrigerated compartment in an opening and closing manner, and the sealing effect of the opening and closing connection between the rear door panel and the refrigerated compartment is poor, which has the defect of affecting the refrigeration effect. Summary of the Invention

[0005] In order to improve the refrigeration effect of a refrigerated compartment, the present application provides a sealing device for a rear door panel of a refrigerated compartment.

[0006] The sealing device for the rear door panel of a refrigerated compartment provided in this application adopts the following technical solution:

[0007] A sealing device for a rear door panel of a refrigerated compartment comprises a compartment, a baffle being provided on one side of the compartment, a mounting groove being provided on the side wall of the compartment facing the baffle, the mounting groove being provided around the inner cavity of the compartment, the mounting groove being arranged as a square groove, a mounting block being fixedly provided on the side wall of the baffle facing the compartment and being plugged into and adapted for the mounting groove, a fixing plate being fixedly provided on both sides of the compartment, a hanging plate being fixedly provided on one end of the fixing plate away from the compartment, a limiting rod being slidably connected to the hanging plate in a vertical direction, a first inclined surface being provided on the side of the limiting rod facing away from the compartment, a reset plate being fixedly provided on the end of the limiting rod away from the baffle, and a spring being fixedly provided between the reset plate and the baffle.

[0008] By adopting the above technical solution, the staff moves the baffle and inserts the mounting block into the mounting groove, thereby completely covering the inner cavity of the compartment with the baffle. At the same time, the baffle and the compartment are pressed tightly together through the limiting rod, so that it is not easy for a gap to exist between the baffle and the compartment, thereby enhancing the sealing effect and achieving the purpose of improving the refrigeration effect of the refrigerated compartment.

[0009] The two wheels are connected in a direction of rotation, and the two wheels are connected in a direction of rotation of the first gear and the second gear are connected in a direction of rotation of the gear to the rotation of the gear.

[0010] By adopting the above technical solution, the rotating motor starts to rotate the threaded rod through the active bevel gear and the driven bevel gear, and the cavity makes it difficult for the movable plate to rotate with the threaded rod, so that the threaded rod causes the movable plate to move in the horizontal direction. When the movable plate moves, the first push rod and the second push rod squeeze the baffle, so that the baffle causes the first slide bar to slide along the first slide groove. When the first slide bar slides to the end of the first slide groove, the baffle continues to be squeezed, so that the baffle rotates around the central axis of the first slide bar, thereby flipping the baffle to open the inner cavity of the compartment, without the need for manual operation by the staff, and achieving the effect of conveniently opening the inner cavity of the compartment.

[0011] Optionally, the two side walls of the first guide plates facing away from each other are both equipped with cylinders, and the side wall of the first guide plate facing the cylinder is penetrated by a avoidance hole for the cylinder piston rod to pass through, and the end face of the first slide rod facing the first guide plate is provided with a socket adapted for sliding with the cylinder piston rod.

[0012] By adopting the above technical solution, when the first sliding rod slides to the end of the first sliding groove, the cylinder is started and the piston rod of the cylinder is inserted into the socket. When the baffle rotates around the first sliding rod, the cylinder limits the first sliding rod, thereby achieving the effect of improving the rotation stability of the baffle.

[0013] Optionally, second guide plates are fixedly provided on both sides of the bottom of the compartment in the horizontal direction, and second sliding grooves are provided on the opposite side walls of the two second guide plates. The second sliding grooves pass through the end faces of both ends of the second guide plates, and a second sliding rod is slidingly connected in the second sliding grooves. The end of the second sliding rod away from the second guide plate is fixedly connected to the bottom of the baffle.

[0014] By adopting the above technical solution, when the baffle moves in the horizontal direction, the baffle causes the second sliding rod to slide along the second sliding groove, thereby achieving the effect of improving the horizontal movement stability of the baffle.

[0015] Optionally, the two second guide plates are fixed with an arc-shaped plate at one end away from the compartment body, and the opposite side walls of the two arc-shaped plates are provided with an arc-shaped groove adapted for sliding with the second slide rod. The arc-shaped groove passes through the end faces of both ends of the arc-shaped plate, and the arc-shaped groove is connected to the second slide groove.

[0016] By adopting the above technical solution, when the baffle rotates, the baffle causes the second slide bar to slide along the arc groove, and the arc plate guides the second slide bar, thereby achieving the effect of the arc plate assisting the baffle in rotating.

[0017] Optionally, the first push rod and the second push rod are respectively located at the top and bottom of the movable plate, and a groove is provided on the side wall of the first push rod facing away from the movable plate. The groove passes through the top wall and the bottom wall of the first push rod, and a fixed roller is fixed in the groove in the horizontal direction. The circumferential side wall of the fixed roller is provided with a roller, and the roller is rotatably connected to the fixed roller.

[0018] By adopting the above technical solution, when the baffle rotates, the sliding friction between the first push rod and the baffle is replaced by rolling friction, which reduces the friction between the first push rod and the baffle, thereby reducing the resistance encountered by the baffle when rotating.

[0019] Optionally, a winding drum is provided on both sides of the threaded rod, and a pull rope is wrapped around the circumferential side wall of the winding drum. One end of the pull rope is fixedly connected to the winding drum, and the other end of the pull rope passes through the baffle and extends to the outside. A limit block is fixedly provided at one end of the pull rope passing through the baffle, and a roller is fixed in the winding drum. One end of the roller is rotatably connected to the compartment body, and a transmission assembly is provided between the roller and the rotating motor to drive the roller to rotate.

[0020] By adopting the above technical solution, when the baffle falls back to the vertical state, the transmission assembly continues to reel in the pull rope through the roller. During the reeling process of the pull rope, the pull rope pulls the baffle through the limit block, thereby pressing the baffle against the car body, thereby closing the inner cavity of the car body. No manual operation is required by the staff, thereby achieving the effect of conveniently closing the inner cavity of the car body.

[0021] Optionally, the box body is provided with an avoidance groove on the inner wall near the rotating motor at the cavity, and the transmission assembly is arranged in the avoidance groove. The transmission assembly includes a driving wheel, a driven wheel and a transmission belt. The driving wheel is fixed on the output shaft of the rotating motor, the driven wheel is fixed on the rotating roller, and the transmission belt passes around the driving wheel and the driven wheel.

[0022] By adopting the above technical solution, the rotating motor rotates the driving wheel, the driving wheel rotates the driven wheel through the transmission belt, and the driven wheel rotates the roller, thereby achieving the effect of the transmission component driving the roller to rotate.

[0023] Optionally, the end surfaces at both ends of the movable plate are spherically hinged with balls, and the balls are rollingly adapted to the inner top wall and inner bottom wall of the compartment at the cavity.

[0024] By adopting the above technical solution, when the moving plate moves, the sliding friction between the moving plate and the car body is replaced by rolling friction, which reduces the friction between the moving plate and the car body, thereby reducing the resistance encountered by the moving plate when moving.

[0025] Optionally, the baffle is rotatably connected to a turntable on the side facing away from the body, and both sides of the turntable are provided with limit holes that are compatible with the limit rod, and the side walls on both sides of the limit rod are provided with a second inclined surface, and a handwheel is provided on the side of the turntable facing away from the baffle, and a connecting shaft is fixed between the handwheel and the turntable.

[0026] By adopting the above technical solution, the rotating turntable squeezes the limit rod through the second inclined surface, thereby moving the limit rod away from the baffle, so that the limit rod does not block the movement of the baffle. With the above structure, the turntable squeezes the two limit rods at the same time, achieving the effect of reducing the workload of the staff.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The baffle is pressed against the compartment body by the limiting rod, and the baffle completely covers the inner cavity of the compartment body, thereby enhancing the sealing effect and achieving the purpose of improving the refrigeration effect of the refrigerated compartment;

[0029] 2. The rotary motor starts to rotate the threaded rod through the driving bevel gear and the driven bevel gear. The threaded rod causes the first push rod and the second push rod to squeeze the baffle through the moving plate. When the first slide rod slides to the end of the first slide groove, the squeezed baffle rotates around the central axis of the first slide rod, achieving the effect of conveniently opening the compartment cavity;

[0030] 3. When the first slide bar slides to the end of the first slide groove, the piston rod of the cylinder is inserted into the insertion hole, and the first slide bar is limited by the cylinder, thereby achieving the effect of improving the rotation stability of the baffle.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-7 This application is described in further detail.

[0040] An embodiment of the present application discloses a sealing device for a rear door panel of a refrigerated compartment.

[0041] refer to Figure 1 and Figure 2, a sealing device for a rear door panel of a refrigerated compartment includes a compartment 1, a baffle 2 is provided on one side of the compartment 1 in a vertical direction, and two first sliding bars 22 and two second sliding bars 23 are fixedly provided at the top and bottom of the baffle 2 in the horizontal direction respectively, and the two first sliding bars 22 and the two second sliding bars 23 are respectively arranged on both sides of the baffle 2, and a first guide plate 12 is fixed on both sides of the top of the compartment 1, and the first guide plate 12 is arranged in a direction perpendicular to the first sliding bar 22, and the side walls opposite to the two first guide plates 12 are provided with a first sliding groove 121 that is slidably adapted to the first sliding bar 22 along their own length direction, and the first sliding groove 121 only passes through the end surface of the first guide plate 12 close to the compartment 1, and a second guide plate 15 is fixed on both sides of the bottom of the compartment 1, and the second guide plate 15 is arranged in a direction perpendicular to the second sliding bar 23, and the side walls opposite to the two second guide plates 15 are provided with a second sliding groove 151 that is slidably adapted to the second sliding bar 23 along their own length direction, and the second sliding groove 151 passes through the end surfaces at both ends of the first guide plate 12.

[0042] When the inner cavity of the compartment 1 needs to be opened, the baffle 2 is squeezed and slides horizontally away from the compartment 1, driving the first slide bar 22 to slide along the first slide groove 121. At the same time, the baffle 2 drives the second slide bar 23 to slide along the second slide groove 151. When the first slide bar 22 slides to the end of the first slide groove 121 away from the compartment 1, the second slide bar 23 slides out of the second slide groove 151, and then the baffle 2 rotates around the central axis of the first slide bar 22. When the inner cavity of the compartment 1 needs to be closed, the baffle 2 rotates around the first slide bar 22 due to its own gravity and falls back to a vertical state. At this time, the second slide bar 23 slides into the second slide groove 151, and then the baffle 2 is pulled towards the compartment 1 until the baffle 2 and the compartment 1 are tightly abutted.

[0043] refer to Figure 1 and Figure 3 , hanging plates 31 are arranged horizontally above and below the baffle 2, and the end of the hanging plate 31 away from the car body 1 is slidably connected to the limiting rod 311 in the vertical direction, and a fixing plate 3 is fixedly arranged between the other end of the hanging plate 31 and the car body 1 in the vertical direction, and a reset plate 3112 is provided on the side of the hanging plate 31 away from the baffle 2, and the reset plate 3112 is fixedly connected to the end of the limiting rod 311, and a spring 3113 is fixed between the reset plate 3112 and the hanging plate 31, and the spring 3113 is sleeved on the circumferential side wall of the limiting rod 311.

[0044] refer to Figure 3 and Figure 4 A first inclined surface 3111 is formed on the side wall of the limiting rod 311 facing away from the compartment 1 , and a second inclined surface 3114 is formed on the side walls on both sides of the limiting rod 311 .

[0045] refer to Figure 1 and Figure 3The baffle 2 is rotatably connected to the side wall of the compartment 1 with a turntable 24. The turntable 24 is circular, and the edge of the turntable 24 is tangent to the edge of the baffle 2. The side walls on both sides of the turntable 24 are provided with limiting holes 241 that are plugged into and adapted to the limiting rod 311. The side wall of the turntable 24 away from the baffle 2 is fixed with a connecting shaft 242. The connecting shaft 242 is located at the center of the turntable 24, and a handwheel 2421 is fixed to the end of the connecting shaft 242 away from the turntable 24.

[0046] When the inner cavity of the compartment 1 needs to be opened, the staff rotates the handwheel 2421, which drives the connecting shaft 242 to rotate. The rotation of the connecting shaft 242 drives the turntable 24 to rotate. The turntable 24 squeezes the limiting rod 311 through the second inclined surface 3114. The limiting rod 311 is squeezed out of the limiting groove. At this time, the spring 3113 is in a compressed state. After the baffle 2 passes the limiting rod 311, the spring 3113 releases its elastic force and drives the limiting rod 311 to return to its original position. When the inner cavity of the compartment 1 needs to be closed, the baffle 2 squeezes the limiting rod 311 through the first inclined surface 3111. The limiting rod 311 is squeezed and moves away from the baffle 2. At this time, the spring 3113 is in a compressed state. After the baffle 2 passes the limiting rod 311, the staff rotates the handwheel 2421 to drive the turntable 24 to rotate until the limiting hole 241 is aligned with the limiting rod 311. The spring 3113 releases its elastic force and inserts the limiting rod 311 into the limiting hole 241.

[0050] During the process of opening the inner cavity of the compartment 1, when the baffle 2 rotates around the central axis of the first slide rod 22, the baffle 2 drives the second slide rod 23 to slide from the second slide groove 151 into the arc-shaped groove 1521, and then the baffle 2 continues to rotate to drive the second slide rod 23 to slide out of the arc-shaped groove 1521; during the process of closing the inner cavity of the compartment 1, when the baffle 2 rotates and falls back around the central axis of the first slide rod 22, the baffle 2 drives the second slide rod 23 to slide into the arc-shaped groove 1521, and then the baffle 2 continues to rotate to drive the second slide groove 151 to slide from the arc-shaped groove 1521 into the second slide groove 151.

[0051] refer to Figure 2 A mounting groove 11 is provided on the side wall of the box body 1 facing the baffle 2. The mounting groove 11 is opened around the inner cavity of the box body 1. The mounting groove 11 is set as a square groove. A mounting block 21 is fixed on the side wall of the baffle 2 facing the box body 1 and is plugged into and adapted to the mounting groove 11.

[0054] refer to Figure 6 The movable plate 4 is internally threaded with a threaded rod 43. Both ends of the threaded rod 43 pass through the movable plate 4 and extend to the outside. The end of the threaded rod 43 away from the baffle 2 is rotatably connected to the inner wall of the compartment 1. The other end of the threaded rod 43 is fixed with a fixed block 432, which abuts against the baffle 2.

[0055] During the process of opening the inner cavity of the compartment 1, the threaded rod 43 rotates to drive the movable plate 4 to move outward; during the process of closing the inner cavity of the compartment 1, the threaded rod 43 rotates in the opposite direction to drive the movable plate 4 to move inward. During the movement of the movable plate 4, the movable plate 4 drives the ball 44 to roll.

[0063] The implementation principle of the sealing device of the rear door panel of a refrigerated compartment in an embodiment of the present application is as follows: when opening the inner cavity of the compartment 1, the staff rotates the turntable 24 to squeeze the limiting rod 311 out of the limiting hole 241, and then starts the rotating motor 14. The rotating motor 14 rotates forward through the active bevel gear 141 and the driven bevel gear 431 to drive the threaded rod 43 to drive the movable plate 4 to move toward the direction close to the baffle 2. At the same time, the rotating motor 14 causes the winding drum 5 to release the pull rope 51 through the transmission assembly 6, so that the movable plate 4 moves the baffle 2 away from the compartment 1 through the first push rod 41 and the second push rod 42. The movable plate 4 continues to approach the baffle 2, and the movable plate 4 causes the roller 4121 to continue to squeeze the baffle 2 through the first push rod 41. At this time, the baffle 2 rotates around the first slide rod 22. When the inner cavity of the compartment 1 is closed, the rotary motor 14 is started and rotated in reverse. The rotary motor 14 moves the movable plate 4 away from the baffle 2 through the active bevel gear 141 and the driven bevel gear 431. At the same time, the rotary motor 14 causes the winding drum 5 to reel in the pull rope 51 through the transmission assembly 6, so that the first push rod 41 moves away from the baffle 2 and the baffle 2 falls back around the first slide rod 22. When the baffle 2 falls back to a vertical state, the pull rope 51 presses the baffle 2 against the compartment 1 through the limit block 511. Then the staff rotates the turntable 24 to make the limit rod 311 plug and fit with the limit block 511. Through the above structure, the purpose of improving the refrigeration effect of the refrigerated compartment is achieved.

[0064] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
