TECHNICAL FIELD

[0001] The present application relates to a cargo blocking rod for blocking or fixing the cargo on a truck, van, airplane, ship or other vehicle to prevent the cargo from moving. BACKGROUND

[0002] In the logistics industry or the process of transporting civilian goods, people often use ropes and binding belts to bind and fix the cargo. For some situations where it is inconvenient or unnecessary to bind the cargo with ropes or binding belts, such as containers, vans, pickup trucks and even passenger cars, people have invented cargo blocking rods to block and fix the cargo, or to further limit the movement of the cargo by increasing the blocking in cooperation with the binding, thereby increasing the safety of transportation.

[0003] Generally, the cargo blocking rod is a telescopic rod with two ends abutting against the inner side walls of the vehicle compartment, or the ceiling and deck inside the vehicle compartment. The cargo blocking rod has an external fixed tube and an internal telescopic tube. An external cast steel rack is connected to the internal telescopic tube, and a cast steel handle with teeth is mounted on the external fixed tube. The teeth on the handle can engage with the rack, and pulling the handle can push the inner tube out to contact and tighten against the side walls of the vehicle compartment to achieve the purpose of blocking the cargo. In terms of structure, one end of the rack is fixed to the inner tube, and the other end is not fixed, extending and protruding outside the outer tube. This structure has poor rack positioning and makes the size of the blocking rod larger and the weight heavier, which is inconvenient to operate. At the same time, the handle with teeth and the rack are made of steel, which has a high production cost and is not conducive to environmental protection. In addition, the lock catch and button of the conventional cargo blocking rod are arranged on the side surface, so the force is unilaterally applied, which not only affects the strength but also easily causes accidental contact, affecting the reliability of the locking.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 4 As shown, the cargo stop bar of the present invention is mainly composed of an inner tube 2, an outer tube 1, a rack 5, a seat 14, a handle assembly, and a locking assembly, wherein:

[0033] The inner and outer tubes 2 and 1 are fitted together in shape. They can be round, square, or irregularly shaped tubes, etc. Preferably, the outer tube 1 in this embodiment is round, and the inner tube 2 is a D-shaped tube (with a D-shaped cross-section), allowing the rack 5 to be mounted on the plane of the D-shaped tube. The first end 202 of the inner tube 2 is connected to a support foot 3 via bolts 19 and nuts 20. The support foot 3 is covered with a foot pad 4. The foot pad 4 is usually made of soft material, which protects the surface of the carriage that contacts the stop bar from scratching, and also increases the friction between the stop bar and the carriage surface, reducing the risk of detachment. The second end 203 of the inner tube 2 is inserted into the first end 103 of the outer tube 1 and is confined within the outer tube by a mutual limiting structure, preventing it from being pulled out of the outer tube 1. The first end 103 of the outer tube 1 is connected to a base 14 for mounting the handle assembly and the locking assembly. The first end 103 of the outer tube 1 has an opening and a limiting hole 102. The opening is a clearance hole 101, through which the gear 6 on the handle 9 meshes with the rack 5 fixed on the inner tube 2. The limiting hole 102 is used to set a limiting piece 13 to fix the base 14. The second end 104 of the outer tube 1 is connected to a support foot 3 with a soft foot pad 4.

[0034] The seat 14 has a saddle-shaped structure with three open sides. It has a base 143 that is adapted to the shape of the outer tube 1 and two sidewalls 141 extending upward from both sides of the base 143. The base 143 is C-shaped and fits onto the first end 103 of the outer tube 1. The two sidewalls 141 are vertically parallel and form a space for accommodating the handle 9, gear 6, and latch 11. The handle 9 and latch 11 can be pivotally connected to the two sidewalls 141 through the second pivot and the first pivot, respectively, so that they can pivot around the pivot. The second pivot and the first pivot can be bolts, pins, or rivets, but bolts as shown in the embodiment figure are preferred, namely the handle bolt 15 and the latch bolt 16 shown in the figure. Both the handle bolt 15 and the latch bolt 16 are equipped with nuts 20. In addition, the seat 14 is provided with fixing holes 142 for fixing to the outer tube 1, which allow the two ends of the limiting piece 13 to be inserted. During assembly, the limiting piece 13 is inserted into the limiting hole 102 and fixed with the fixing hole 142 on the seat 14. The limiting piece 13 not only limits and fixes the seat 14 to the outer tube 1, but also can withstand the axial pressure generated when the inner and outer tubes of the stop rod are working.

[0035] The handle assembly includes a handle 9 and a gear 6. The front of the handle has two spaced-apart side plates 91, with the gear 6 centrally positioned between the two side plates 91. A pad 7 is provided between the gear 6 and the side plates 91. The gear 6 and the pad 7 can also be made as a single piece of gear, but it is preferred to be joined together for easier stamping. This allows it to be constructed by joining multiple stamped gear pieces 60 and pads 7. Figure 1 As shown, gear 6 is composed of two gear plates 60 joined together, with a pad 7 mounted on each side. Gear plate 60 is not a complete circle; instead, several protruding teeth 601 are stamped on its head circumference. These protruding teeth 601 are not standard involute teeth. Holes for handle bolts 15 and fixing pins 8 are provided at the head and tail of gear plates 60 and pads 7. The fixing pin hole at the tail is one or more, allowing connection to handle 9 as a whole via one or more fixing pins 8. Handle 9 is connected to base 14 via handle bolts 15, and a locking pin 10 is mounted in the middle of handle 9, connecting to two side plates 91.

[0036] The lock catch assembly is used for locking or unlocking the handle 9, and comprises a lock catch 11 which is connected in the middle of the two side wall portions 141 of the seat body 14 through a lock catch bolt 16, and is provided with torsion springs 12 on the two sides to keep the lock catch 11 in a vertical state, and the top of the lock catch 11 can be rotated counterclockwise around the lock catch bolt 16 by pressing. The elastic member 12 is a double torsion spring, and the two ends are arranged on the two sides of the lock catch 11 and limit the axial movement of the lock catch 11 along the lock catch bolt 16, so that the lock catch 11 is kept in the middle of the two side wall portions 141 of the seat body 14 and has a tendency to be locked. The lock catch 11 is provided with a lock hook 111 and a guide sliding slope 112, and the lock hook 111 locks the lock pin 10 in working to limit the rotation of the handle 9. The lock pin 10 is mounted on the handle 9 and cooperates with the lock hook 111 to lock or unlock, and when the lock hook 111 is locked on the lock pin 10, the handle 9 is in a locked state and cannot be rotated; when the lock hook 111 is unlocked from the lock pin 10, the handle 9 is in an unlocked state and can be rotated. The lock catch 11 is centrally arranged, the force direction thereof is in the same plane as the shaft center line of the blocking rod, so that the force is uniform and the strength is improved, and the two sides are protected by the handle 9 and the seat body 14, so that the release caused by accidental impact can be prevented and the safety in use is improved.

[0037] As Figure 8 The rack 5 is a long strip-shaped stamping part, and does not have a traditional involute tooth shape, but has a plurality of equidistantly distributed stamping holes 501 in the length direction, and the stamping holes 501 can be meshed with the convex teeth 601. Both ends of the rack 5 are provided with mounting holes 502 for mounting fasteners, so that the two ends of the rack 5 are fixedly connected to the mounting plane 201 of the inner tube 2 through the first fastener and the second fastener respectively, and the first fastener and the second fastener can be bolts, pins or rivets. The mounting holes 502 can be circular or square, and in the embodiment, the mounting holes are preferably square holes, and the first fastener and the second fastener are preferably long bolts 17 and short bolts 18.

[0038] The inner tube 2 of the present application is preferably a D-shaped tube with a mounting plane 201, so that the cross section of the rack 5 is also preferably a plane, and the bottom plane is attached to the mounting plane 201. Of course, the rack 5 and the inner tube 2 of the present application are not limited to the embodiment described, and the inner tube 2 can also be a circular tube without a mounting plane 201, and the rack 5 is also adaptively changed to have a circular arc cross section.

[0039] The inner tube 2 provided with the rack 5 is mounted in the outer tube 1, and the head of the short bolt 18 is higher than the surface of the rack 5, and when the inner tube 2 is pulled out (to the left, that is, the first end of the inner tube moves away from the first end of the outer tube), the head of the short bolt 18 will hit the limiting piece 13, so that it cannot be pulled out any more, that is, the short bolt 18 and the limiting piece 13 constitute a limiting structure between the inner tube 2 and the outer tube 1, so that the second end 203 of the inner tube 2 is axially movably limited in the first end 103 of the outer tube 1.

[0040] Again in combination Figures 9 to 11The dynamic process of the application is described as follows:

[0041] As Figure 9 , the lock 11 is pressed down, the lock 11 rotates anticlockwise around the lock bolt 16, the hook 101 is separated from the lock pin 10, and the handle 9 can rotate anticlockwise around the handle bolt 15, driving the gear 6 to rotate synchronously. The convex teeth 601 on the gear 6 rotate into the holes 501 of the rack, engaging with the holes 501, so as to pull the rack 5 and the inner tube 2 to move axially to the right.

[0042] As Figure 10 , when the handle 9 is fully opened, the convex teeth 601 on the gear 6 are separated from the holes 501 on the rack 5, and the inner tube 2 and the outer tube 1 can move axially left and right relative to each other to adjust the total length of the cargo barrier to a suitable length.

[0043] As Figure 11 , after adjusting the length, the handle 9 is rotated clockwise, the convex teeth 601 engage with the holes 501 again, driving the rack 5 and the inner tube 2 to move axially to the left, and the support foot 3 with the foot pad 4 is pressed tightly on the wall 21 of the vehicle compartment. During the pressing of the handle 9, the lock pin 10 contacts the guide and slide inclined surface 112 on the upper part of the hook 111, and the lock 11 is pushed to rotate anticlockwise. When the lock pin 10 enters the hook 111, the lock 11 is reset under the action of the torsion spring 12, and the handle 9 is locked, i.e. Figure 5 , the state, and the cargo barrier is fully tightened and locked, entering the working state. In the working state, the convex teeth 601 on the gear 6 are located in the avoidance hole 101 of the outer tube 1 and are in engagement with the hole 501.

[0044] After use, the actions of Figure 9 and Figure 10 are repeated to release the axial support force on the barrier and remove the cargo barrier.
