Technical Field

[0001] The present invention relates to a partition system, and more particularly to a van partition system. Background Art

[0002] In existing vans, partitions are generally used to partition the cargo in the van, or the cargo is tied up with ropes to classify the cargo. However, the partitions and other dividing devices must be removed each time the cargo is loaded and unloaded. Otherwise, the cargo cannot be loaded and unloaded. The above operations are complicated and are not conducive to improving the cargo loading and unloading efficiency of the van.

[0003] For example: Chinese patent announcement number CN2855872Y, announcement date January 10, 2007, utility model name is a van structure, the application discloses a van partition device, including partitions and compartment panels, the partitions divide the compartment into front, middle, and rear compartments, the solution can increase the internal space of the compartment and increase the loading volume, but the partition structure of the solution needs to be loaded and unloaded together with the goods to ensure the separation of the goods, and the size of the partition space cannot be changed at will. Summary of the invention

[0004] The present invention overcomes the problems of complicated cargo loading and unloading and partitions after the existing van is partitioned, and provides a van partitioning system. This solution can easily store and unfold the partitioning device to achieve van partitioning without causing chaos in the van.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a partition system for a van, including a van body, and also including a plurality of strut mechanisms fixed side by side inside the van body, a rotatable belt reel tube fixed on the strut mechanism, and a belt reel rotatably connected to the belt reel tube. The strut mechanism is used as a framework of the partition system, and is used to tension the cloth to form a partition space. The belt reel tube is rotatably connected to the belt reel, so that the belt reel can be rotated and rolled up, and can also be stretched and unfolded, so as to quickly form a partition space in the van body.

[0006] Preferably, at least one first web corresponding to the support rod mechanism is provided on each of the upper and lower sides of the box body, and at least two second webs are provided on at least one side of the left and right sides. The first web is provided on the top plate and the floor of the box body, and is used to fix the upper and lower ends of the support rod mechanism to form a partition frame. At least one side of the two sides of the box body needs to be provided with a second web, and the second web is mainly used for the stretching and locking of the tape. When the tape is stretched, the stretched end of the tape needs to be fixed on the second web to form a partition space.

[0007] Preferably, the support rod mechanism comprises an inner tube and an outer tube which is sleeved outside the inner tube and can rotate relatively, the two ends of the inner tube are respectively fixedly connected to the top and bottom of the box body through the first web, and the outer tube is fixedly connected to the two ends of the reel tube through the connecting rod. The support rod mechanism is composed of inner and outer tubes, the inner tube is used to be fixed on the first web to fix the entire support rod mechanism, and the outer tube is rotatably connected to the outside of the inner tube. When the reel is stretched in various directions, the outer tube will rotate along the stretching direction of the reel, thereby reducing the torsion force on the outer tube, and can prevent the reel from generating a force perpendicular to the connecting rod on the reel tube and breaking the connecting rod. The reel tube is fixed to the outer tube through the connecting rod, and there is a space for storing the reel between the reel tube and the outer tube, so as to ensure that the reel can be completely stored on the reel tube, and the rotation of the outer tube around the inner tube and the rotation of the reel around the reel tube are independent.

[0008] Preferably, the stretched end of the tape is provided with a connecting buckle corresponding to the position and number of the second web along its width direction, and the two ends of the connecting buckle are provided with a slot connected to the second web. The stretched end of the tape is provided with a connecting buckle, and the position of the connecting buckle corresponds to the position of the second web, and the number of the connecting buckle also needs to correspond. In order to fix the two ends of the tape in the width direction, the number of the connecting buckle and the second web is at least two, and the two ends of the connecting buckle are provided with a slot, which can be clamped and fixed with the second web, so as to fix the stretched tape to form a partition space.

[0009] Preferably, a lock handle is rotatably connected to the interior of the connecting buckle via a rotating shaft, one end of the lock handle is elastically connected to the inner end surface of the connecting buckle via an elastic member, and the other end is L-shaped and stepped. In order to facilitate the connection between the connecting buckle and the second web, the lock handle is rotatably connected to the interior of the connecting buckle, and when the lock handle rotates to put the elastic member in a compressed state, the connecting buckle can be inserted into the second web, and after the lock handle is released, the L-shaped step on the lock handle can lengthen the distance of the connecting buckle slot, so that the slot cannot be separated from the second web, thereby achieving a better fixing and anti-slipping effect.

[0010] Preferably, the first web is provided with a plurality of adjustment holes evenly distributed along the parallel direction of the strut mechanism, and the second web is provided with a plurality of interfaces adapted to the connecting buckle evenly distributed. The first web is provided with a plurality of adjustment holes, each of which can be fixed to the inner tube of the strut mechanism, and the size of the partition space can be arbitrarily changed by fixing the strut mechanism in different adjustment holes; the second web is provided with a plurality of interfaces, the size of which is fixed and can be connected to the card slot of the connecting buckle.

[0011] Preferably, the two ends of the tape tube are provided with tape limit blocks with a spacing matching the tape width. The tape limit blocks at both ends of the tape tube are mainly used to limit the position of the tape to prevent the tape from shifting during storage, and the distance between the two tape limit blocks needs to be adapted to the tape width to achieve a better storage effect.

[0012] Preferably, one end of the tape reel tube is provided with a tape reel tube controller adjacent to the tape reel limit block, and a coil spring is provided inside the tape reel tube controller. The tape reel tube controller can be set at any end of the tape reel tube, but for the convenience of operation and use, the tape reel tube controller is generally set on the side close to the bottom plate for the convenience of use by the staff. A coil spring is provided inside the tape reel tube to realize automatic storage of the tape on the tape reel tube. When the tape is stretched, the coil spring can also generate a restoring torque to tighten the tape, which plays a role in limiting and fixing the goods. When the tape needs to be stored, the connecting buckle is removed, and the tape reel tube automatically stores the tape under the action of the coil spring.

[0013] Preferably, the tape limit block is provided with a plurality of limit grooves in the circumference, and the tape tube controller is provided with a protrusion in the circumference, and the protrusion is internally connected and rotatably connected with a limit fixing block that matches the limit groove. The tape limit block is fixed to the tape tube, and when the tape tube rotates, the tape limit block will also rotate together. Therefore, in order to fix the tape tube and stop it from rotating, a limit groove is provided on the tape limit block, and the limit fixing block cooperates with the limit groove to clamp the limit groove, thereby clamping the tape tube and stopping it from rotating, thereby achieving the fixation of the tape after storage or unfolding. The limit fixing block is provided on the circumference of the tape tube controller, and the tape tube controller is directly fixed on the connecting rod, so that the tape tube controller and the protrusion are both in a fixed state, and the fixed limit block on the protrusion is also in a fixed state. The limiting fixing block passes through the protrusion and can rotate inside the protrusion. The part passing through the protrusion is a semi-cylinder, which can cooperate with the limiting groove on the tape limiting block to fix the limiting groove and further fix the tape tube.

[0014] Preferably, the connection part between the limit fixing block and the protrusion is provided with a slide groove and a fixed groove, and the protrusion is provided with through holes at the positions corresponding to the slide groove and the fixed groove, and the through holes are provided with guides and fixings connected with the slide groove and the fixed groove, respectively. The slide groove and the guide are used in combination to enable the limit fixing block to rotate inside the protrusion without being separated from the protrusion. The guide is fixed inside the through hole corresponding to the slide groove, and the guide also includes a steel ball that cooperates with the slide groove to play an axial fixing and circumferential guiding role for the fixed limit block. The fixing groove and the fixing are used in combination, and the fixing is fixed inside the through hole corresponding to the fixing groove, and also includes a spring and a steel ball. The fixing groove is circumferentially arranged on the limit fixing block, and there are several fixing grooves. When the steel ball contacts the fixing groove, the pressure of the spring is reduced, and it can resist the limit fixing block to prevent it from rotating; when the steel ball contacts the cylindrical surface of the limit fixing block, the pressure of the spring is increased, and the limit fixing block can be rotated arbitrarily.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) it can quickly partition the interior of a van to prevent confusion of cargo; (2) it can adjust the size of the partition space in the van; (3) it can quickly store the partition device, and the storage of the roll is very convenient; (4) it is simple to operate and easy to use, and can improve the efficiency of loading and unloading cargo.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0026] Example 1: Figures 1 to 7A van partitioning system shown in the figure includes a body 1, two first webs 5 along the direction of the van body are arranged between the upper top plate and the lower top plate in the middle position of the body 1, and two parallel rows of support rod mechanisms 2 are installed in the body 1 along the first webs 5, and the support rod mechanisms 2 include an inner tube 7 and an outer tube 8. The inner tube 7 is directly connected to the first web 5 and fixed on the upper top plate and the lower bottom plate of the body 1. The two ends of the outer tube 8 are connected to a reel tube 3 through a connecting rod 9. A reel 4 is wound on the reel tube 3. A reel tube controller 19 is provided at one end of the reel tube 3. The reel tube 3 can be rotated by a coil spring 20 inside the reel tube controller 19, so that the reel 4 can be stretched and stored on the reel tube 3. Three second webs 6 are provided on each of the two side surfaces of the body 1, which are respectively arranged at the top, bottom and middle of the side surface of the body 1, and three connecting buckles 10 are provided at the stretching end of the roll 4 along its width direction. The connecting buckles 10 are respectively arranged at the two ends and the middle of the roll 4 in the width direction, corresponding to the positions of the second webs 6.

[0027] When the tape 4 is stretched, the tape 4 can be pulled out of the tape tube 3 and stretched, and then the connecting buckles 10 on the tape 4 are correspondingly snapped onto the second web 6 to fix the tape 4, thereby forming a partitioned space in the van.

[0028] like Figure 3 and Figure 4 As shown, both ends of the tape tube 3 are provided with tape limit blocks 18, which are gear-like in shape, with limit grooves 21 arranged circumferentially, and the distance between the two tape limit blocks 18 is adapted to the width of the tape 4, so that the tape 4 can be stored for deviation correction, and the tape 4 can be prevented from being wound unevenly, and it is also more convenient to pull out the tape 4 when the tape 4 is stretched. A tape tube controller 19 is also provided at one of the tape limit blocks 18, and the tape tube controller 19 is arranged between the connecting rod 9 and the tape tube 3 and fixed to the connecting rod 9, and a coil spring 20 is installed inside the tape tube controller 19, and the coil spring 20 is connected to the tape tube 3 to increase a restoring force for the tape tube 3, so that the tape 4 is stored. A convex block 22 is also provided in the circumference of the tape tube controller 19, and a through hole is provided on the convex block 22 along the axial direction of the tape tube 3, and a limiting fixing block 23 is rotatably connected in the through hole, and the part of the limiting fixing block 23 exposed from the convex block 22 is a semi-cylinder 32, and can be engaged with the limiting groove 21 on the tape limiting block 18; when the semi-cylinder 32 is engaged with the limiting groove 21, the tape tube 3 can be fixed to prevent the tape tube 3 from rotating, and when the limiting fixing block 23 rotates half a circle, the semi-cylinder 32 also rotates half a circle, so that the semi-cylinder 32 is disengaged from the limiting groove 21, so that the tape tube 3 can continue to rotate; Figure 7As shown, the portion where the fixed limit block 23 is connected to the protrusion 22 is provided with a slide groove 24 and a fixing groove 25, and the protrusion 22 at the corresponding position of the slide groove 24 and the fixing groove 25 is respectively provided with a through hole 26, and a guide member 27 and a fixing member 28 are respectively fixed inside the through hole 26. In this scheme, the guide member 27 is composed of a steel ball and a screw, and the screw is threadedly fixed inside the through hole, and the steel ball can cooperate with the slide groove 24, so that the screw supports the steel ball and then cooperates in the slide groove 24, so that the limit fixing block 23 can be axially fixed in the protrusion 22 and can also rotate inside the protrusion 22; the fixing member 28 is composed of a steel ball, a screw and a spring, and a spring is sleeved between the screw and the steel ball, so that the screw and the steel ball cannot directly contact each other, and the steel ball can adapt to the fixing groove 25. When the steel ball is in the fixing groove 25, due to the elastic force of the spring, the steel ball supports the fixing groove 25. When the limit fixing block 23 rotates When the power is not too great, the limit fixing block 23 cannot be rotated, thereby achieving the purpose of locking the limit fixing block 23, thereby making the semi-cylinder 32 unable to rotate, indirectly controlling the rotation of the winding tube 3, and ultimately controlling the stretching and storage of the winding tape 4, and performing the operation of partitioning and restoring the compartment 1; in order to facilitate the application of torque to the limit fixing block 23, a handle 31 is provided at the bottom of the limit fixing block 23, and the limit fixing block 23 can be easily rotated by the handle 31. When the applied force is large enough, the circumferential surface of the limit fixing block 23 will lift the steel ball, and the steel ball compresses the spring to make the steel ball disengage from the fixing groove 25, thereby enabling the limit fixing block 23 to rotate. By tightening or loosening the screw and adjusting the distance between the screw and the steel ball, the minimum torque of the limit fixing block 23 can be changed, thereby preventing the winding tube 3 from being unreliably fixed due to the loss of the winding spring 20 or other structures in the case of long-term use.

[0029] The outer tube 8 of the support rod mechanism 2 is sleeved on the outside of the inner tube 7, and the two can also rotate. When the tape 4 is stretched in various directions, the outer tube 8 will rotate along the stretching direction of the tape 4, thereby reducing the torsion applied to the outer tube 8, and preventing the tape 4 from generating a vertical force on the connecting rod 9 on the tape tube 3, thereby preventing the connecting rod 9 from being twisted off. In order to prevent the rotation between the inner tube 7 and the outer tube 8 from being too arbitrary, damping can be added between the inner tube 7 and the outer tube 8, so that the rotation between the two is relatively stable and has a certain degree of self-adaptation, and can be self-stabilized. There is space between the outer tube 8 and the tape tube 3 for storing the tape 4, to prevent the radius of the tape tube 3 and the tape 4 from increasing when the tape 4 is stored, causing the tape 4 and the outer tube 8 to get stuck.

[0030] like Figure 5As shown, the first web 5 and the second web 6 are both provided with fixing holes 29 for mounting the first web 5 and the second web 6 on the car body 1. Meanwhile, the first web 5 is provided with a plurality of adjustment holes 16 along its length direction. The size of the adjustment holes 16 is adapted to the size of the inner tube 7 of the strut mechanism 2. The inner tube 7 can be installed in any adjustment hole 16, thereby changing the position of the strut mechanism 2, and further changing the position of the winding belt 4, thereby realizing the change of the size of the partition space inside the car body 1. The second web 6 is provided with a plurality of interfaces 17 along its length direction. The interfaces 17 can be engaged with the connecting buckles 10 on the winding belt 4 to fix the stretched end of the winding belt 4 and fix the partitions of the car body 1.

[0031] like Figure 6 As shown, both ends of the connecting buckle are provided with a card slot 11, and the depth of one of the card slots 11 is greater than the depth of the other card slot 11 (the card slot with a larger depth is specified as the first card slot, and the card slot with a smaller depth is specified as the second card slot). The middle part of the connecting buckle 10 is connected to a lock handle 13 through a rotating shaft 12. The lock handle 13 is provided with a card block near one end of the second card slot, and is clamped with an elastic member 14. Corresponding to the position of the card block, a connecting groove is provided inside the connecting buckle 10, and the other end of the elastic member 14 is fixedly connected to the connecting groove; the lock handle 13 is provided with an L-shaped step 15 near one end of the first card slot, and the distance from the rotating shaft 12 to the L-shaped step 15 is greater than the distance from the rotating shaft 12 to the bottom of the first card slot, so the L-shaped step 15 of the lock handle 13 can block the first card slot, so that the depth of the first card slot becomes smaller, thereby changing the distance between the effective bottoms of the two card slots 11. When it is necessary to connect the connecting buckle 10 to the interface 17 on the second web 6, first rotate the locking handle 13 to compress the elastic member 14, rotate the L-shaped step 15 to the outside of the first slot, completely expose the first slot, and then clamp one end of the interface 17 in the first slot. At this time, since the first slot is first placed in the interface 17, and the distance from the bottom of the first slot to the end of the connecting buckle 10 close to the second slot is less than the length of the interface 17, the second slot can also be placed in the interface 17. After the second slot is placed in the interface 17, the bottom of the second slot is abutted against the other end of the interface 17, and then release the locking handle 13. Under the action of the elastic member 14, the L-shaped step 15 is reset, and the first slot is partially blocked again, so that the depth of the first slot becomes smaller, so that it cannot be separated from the interface 17 on the second web 6, thereby achieving the stretching and fixation of the winding belt 4. Figure 2 The enlarged view in FIG. 1 is a schematic diagram of the connection of the connecting buckle 10. The connecting buckle 10 is also provided with a belt hole 30, which is used for a strip or a rope to pass through the belt hole 30 and connect and fix with the winding belt 4.

[0032] like Figure 1 In the above figure and Figure 2As shown, the steps of deploying the partition system of this embodiment are as follows: first, the staff classifies the goods of the same type and places the goods of the same type on the left or right side (assuming the left side) of the inner part of the compartment 1, then loosens the belt tube 3 on the first support rod mechanism 2 near the left side, and loosens the fixing of the cloth stopper 18 on the belt tube 3 by the semi-cylinder 32 by turning the handle 31 where the belt tube controller 19 is located, then pulls out the belt 4, wraps the belt 4 around the outer tube 8 of the second support rod mechanism 2 on the left side, and then connects the three connecting buckles 10 on the belt 4 to the three second webs 6 on the wall of the left compartment 1 respectively, forming the first partition. Then, the goods are placed on the left side adjacent to the first partition (or placed on the right side, where they are still placed on the left side), then loosens the belt tube 3 of the second support rod mechanism 2 on the left side, wraps the belt 4 around the outer tube 8 of the third support rod mechanism 2, and then connects the connecting buckle 10 on the belt 4 to the interface 17 on the second web 6, forming the second partition; and so on. When placing the goods on the right side, the same operation is performed, the belt reel tube 3 on the first support rod mechanism 2 on the right side is loosened, and the belt reel 4 is wrapped around the outer tube 8 of the second support rod mechanism 2 on the right side, and then the connecting buckle 10 on the belt reel 4 is connected to the interface 17 on the second web 6 on the wall of the right side body 1, and so on, finally completing the loading and partitioning of the goods.

[0033] like Figure 1 As shown in the figure below, the storage steps of the partition system of this embodiment are as follows: first, untie the connection between the connecting buckle 10 and the second web 6 on the reel 4 closest to the outside of the car body 1, and under the action of the coil spring 20 inside the reel tube controller 19, the reel tube 3 rotates back by itself, and the reel 4 is rotated and stored together with the reel tube 3. After the reel 4 is completely stored, the semi-cylinder 32 is re-matched with the limit groove 21 of the cloth rolling limit block 18 by rotating the handle 31, and at the same time, the steel ball of the fixing part 28 is just matched with the fixing groove 25, and the screws are properly tightened to prevent the reel tube 3 from rotating under the action of external force, causing the reel 4 to be scattered and messy. After the staff unloads the goods, continue to perform the operations of other partitions with the same operation until all the goods are unloaded.

[0034] Example 2: Figure 8 A van partitioning system is shown, which differs from Example 1 only in that, in this embodiment, there is only one first web 5 at the top and bottom of the body 1, and the first web 5 is installed on one of the left and right sides of the body 1, that is, only one row of support rod mechanisms 2 is used in this embodiment; at the same time, the second web 6 is installed on the side of the body 1 opposite to the support rod mechanism 2.

[0035] The specific implementation steps are different from those of Example 1 only in that there is no left-right distinction between partitions. After the staff has transported the goods to the innermost part of the car body 1, the tape tube 3 on the support rod mechanism 2 is loosened, and then the tape 4 is directly pulled from one side of the car body 1 where the support rod mechanism 2 is installed to the second web 6 on the other side for connection, forming the first partition, and so on, until all the goods are shipped. The storage operation of the tape 4 is also similar.

[0036] The difference between this embodiment and embodiment 1 is that the partitions in this embodiment are larger in the width direction of the compartment 1, which is suitable for partitioning cargo whose length is almost the same as the width of the compartment 1, while the partitions in embodiment 1 are smaller and more numerous, which is suitable for partitioning small cargo.
