Description

Technical Field

[0001] This application relates to the technical field of vehicle towing tools, and particularly to a portable vehicle rescue tool for the wild. Background Art

[0002] Military vehicles perform many tasks in the wild. It often happens that the vehicle gets stuck in mud, desert and other places and cannot drive out. After rain or snow, the wild roads are muddy, especially some dirt roads, forming one trap after another, and the vehicle is very likely to get stuck when passing by. Generally speaking, the driver will reduce the tire pressure and drive at a low speed to avoid the risk of getting stuck. When one side of the tire slips, the driver will also pull the handbrake and increase the throttle to drive out. However, even if the above various means are adopted, there are still situations where the vehicle cannot drive out. At this time, it is necessary to rely on the vehicle winch to carry out self-rescue.

[0003] However, when the vehicle gets stuck in mud, desert and other places, if there is no vehicle or big tree and other fixed objects beside as the fulcrum of the vehicle winch at this time, it is very difficult for the winch to achieve the final rescue purpose. Therefore, in the case of no fulcrum, a tool is needed as the fulcrum, cooperating with the winch, so that the stuck vehicle can get out of trouble. At the same time, the fulcrum should be firm enough and convenient to carry and operate. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a portable vehicle rescue tool for the wild, so as to solve the problem that military vehicles get stuck in mud in the wild and cannot drive out, and there is no fulcrum to cooperate with the winch to achieve self-rescue.

[0030] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0031] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of this application should have the ordinary meanings understood by those of ordinary skill in the field to which this application belongs.

"Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0032] Reference Figure 1 、 Figure 2 、 and

[0033] Specifically, the support plow head 1 plays an overall supporting role. The support plow head 1 can be a whole or a structure formed by combining individual independent components.

[0034] The first rotating end 51 of the pull rod 5 is rotationally connected to the support plow head 1. The rotational connection method can be a rotational connection method realized through a rotating shaft, a pin shaft or other connecting parts, or other conventional rotational connection methods, as long as the rotational connection between the pull rod 5 and the support plow head 1 can be achieved.

[0035] The vertical height of the connecting rod 3 is greater than the vertical height of the wheel winch 10 when in use (i.e., when the wheel winch 10 is installed on the vehicle wheel). In this way, during actual operation, the wheel winch 10 can apply a force to the connecting rod 3 that is towards the support plow head 1 and simultaneously towards the wheel winch 10, thereby making the use of this device more convenient and handy.

[0036] The control rod 4 includes a hand-pressing end 42 and a rotating end 41. The rotating end 41 is rotatably connected to the second rotating end 52 of the pull rod 5. At the same time, the control rod 4 is rotatably connected to the connecting rod 3. The position where the control rod 4 is connected to the connecting rod 3 (hereinafter referred to as "the first position 33") is located between the hand-pressing end 42 and the rotating end 41. An external hand-pressing sleeve can be sleeved on the hand-pressing end 42 to facilitate the operator to hold the hand-pressing end 42 to apply force.

[0037] The connecting end 22 of the swing rod 2 is rotatably connected to the free end 31 of the connecting rod 3. The acting end 21 of the swing rod 2 is configured to be connected to the wheel winch 10. During actual use, the acting end 21 of the swing rod 2 is connected to the wheel winch 10 through a rope 9. When in use, it is ensured that the axial direction of the swing rod 2 is the same as the direction of the rope 9. The connecting end 22 of the swing rod 2 is rotatably connected to the free end 31 of the connecting rod 3, enabling the swing rod 2 to automatically rotate around this support point with the relative changes in the positions of the wheel winch 10 and the support point of the swing rod 2, thereby adjusting the direction of the swing rod 2 so that the axial direction of the swing rod 2 is the same as the direction of the rope 9.

[0038] During specific implementation, when a vehicle gets stuck in a mud pit, desert, etc., if there is no vehicle or big tree and other fixed objects nearby as the fulcrum of the wheel winch 10 at this time, it is very difficult for the winch to achieve the final rescue purpose. At this time, in the absence of a fulcrum, the rescue tool described in this application can be used as a fulcrum and cooperate with the winch to enable the stuck vehicle to get out of trouble.

[0039] When in use, refer to Figure 3 , place the rescue tool described in this application on the ground (preferably on relatively dry and hard land away from the mud pit and desert), then fix the wheel winch 10 on the wheel of the vehicle to be rescued, and connect the acting end 21 of the swing rod 2 to the wheel winch 10 through a rope 9. At this time, the bottom surface of the support plow head 1 is in contact with the ground, the hand-pressing end 42 of the control rod 4 is at the highest point, the rope 9 is straightened, and the axial direction of the swing rod 2 is the same as the direction of the rope 9.

[0040] In this embodiment, for the convenience of description, the position of the wheel winch 10 is hereinafter defined as "front", the position of the hand-pressing end 42 of the control rod 4 is defined as "rear", the position of the ground is defined as "down", and the position of the sky opposite to the ground is defined as "up".

[0041] During specific implementation, the operator presses down the hand-pressing end 42 of the control rod 4. When pressing down the hand-pressing end 42 of the control rod 4, it drives the control rod 4 to rotate around the first position 33, causing the rotating end 41 of the control rod 4 to move upward. At the same time, the trapped vehicle is started, and the driving wheels of the trapped vehicle drive the wheel winch 10 to rotate, causing the drum of the vehicle winch to rotate and wind the rope 9 (at this time, since this tool is not fixed yet and cannot provide a fulcrum for the wheel winch 10, even if the wheel winch 10 rotates, the wheel cannot be driven out). Then, the wheel winch 10 exerts a forward and downward pulling force on the connecting end 22 of the connecting rod 3 through the rope 9 and the swing rod 2. At this time, the connecting rod 3 swings around the first position 33, and the connecting rod 3 exerts a forward traction force on the control rod 4. Therefore, during the process of the control rod 4 rotating under external pressure, it moves forward simultaneously under the traction of the connecting rod 3. Combining the dual actions of the control rod 4 and the connecting rod 3, actually, the hand-pressing end 42 of the control rod 4 moves downward and forward, and the rotating end 41 of the control rod 4 moves upward and forward. The rotating end 41 of the control end drives the swing rod 2 to move forward and upward, and the swing rod 2 drives the part of the support plowshare 1 connected to the swing rod 2 to move forward and upward. Then, the support plowshare 1 swings around the position connected to the connecting rod 3, causing the part of the support plowshare 1 not connected to the swing rod 2 to move forward and downward until the part of the support plowshare 1 not connected to the swing rod 2 extends into the ground and drills into the soil until the part of the support plowshare 1 not connected to the swing rod 2 is blocked by the soil and cannot continue to extend. At this time, the soil has provided sufficient resistance to the support plowshare 1, and the support plowshare 1 is already stable enough. At this time, the device is fixed relative to the ground and can provide a fulcrum for the wheel winch 10. The vehicle driving wheels continue to drive the vehicle winch to rotate, causing the drum of the vehicle winch to rotate and wind the rope 9. On the premise that the rescue tool described in this application does not move, as the rope 9 is continuously wound, the length of the rope 9 gradually shortens, thereby pulling the vehicle out of the trap and realizing the self-rescue of the vehicle.

[0042] As can be seen from the above, the portable field vehicle rescue tool provided in this application serves as a fulcrum for the vehicle winch to cooperate with the winch function to help the trapped vehicle out of trouble; moreover, the support force of this tool is strong enough, and all components are rotatably connected, occupying a small space, being convenient for folding and carrying. Especially when military vehicles are trapped in a quagmire in the wild and there is no other fulcrum, it has very high practicality.

[0043] In some embodiments, at least one top block 13 is provided on one side of the support plowshare 1, and the top block 13 is a cone or the top surface of the top block 13 is an inclined surface.

[0044] Specifically, at least one top block 13 is provided on a side of the support plowshare 1 away from the hand - pressing part. The top block 13 is smaller in volume compared to the side surface of the entire support plowshare 1 and is more likely to penetrate or drill into the deep soil under force. Further, the top block 13 is a cone - shaped body or the top surface of the top block 13 is an inclined surface. Such a setting makes it easier and faster for the top block 13 to penetrate or drill into the deep soil, shortens the time for this tool to penetrate into the soil, reduces the pressure exerted by the operator's hand, and makes the operation more convenient and fast.

[0045] The top block 13 can be provided with one or multiple. When there is one top block 13, the top block 13 is preferably arranged at the central position of the side wall of the support plowshare 1 away from the hand - pressing part. When there are multiple top blocks 13, the multiple top blocks 13 are arranged at intervals on this side wall, so that this device can penetrate into the soil from multiple positions simultaneously, further shortening the time for this tool to penetrate into the soil and increasing the stability of this device.

[0046] In some embodiments, referring to Figure 4 , the support plowshare 1 includes: a main support plate 11, including a support bottom plate 111 and a support platform 112, where the support platform 112 is located on top of the support bottom plate 111; a secondary support plate 12, rotatably connected to the side wall of the support platform 112, and a side groove for receiving the flank 1111 of the support bottom plate 111 is formed on the side wall of the secondary support plate 12.

[0047] Specifically, the flank 1111 of the support bottom plate 111 is the part of the support bottom plate 111 that is not covered by the support platform 112 and is located on the side of the support bottom plate 111. A side groove for receiving the flank 1111 of the support bottom plate 111 is formed on the side wall of the secondary support plate 12. After the flank 1111 of the support bottom plate 111 is inserted into the side groove, the bottom surface of the support bottom plate 111 is flush with the bottom surface of the secondary support plate 12, increasing the total bottom area of the support plowshare 1, that is, increasing the force - bearing area, and at the same time improving the stability of the support plowshare 1, enabling the fulcrum for fixing the wheel winch 10 to be established faster and more firmly.

[0048] The secondary support plate 12 is rotatably connected to the side wall of the support platform 112, enabling the support plate to rotate about the side wall of the support platform 112. When this tool is needed for rescue, rotate the secondary support plate 12 away from the support platform 112 until the flank 1111 of the support bottom plate 111 is caught in the side groove and then stop rotating. At this time, the bottom surface of the support bottom plate 111 is flush with the bottom surface of the secondary support plate 12, increasing the total bottom area of the support plow head 1 and improving the stability of the placement of the support plow head 1. When this tool is not needed for rescue, rotate the secondary support plate 12 towards the support platform 112 until it can no longer rotate. At this time, the volume of the entire support plow head 1 is reduced, facilitating carrying and placement.

[0049] Among them, there are two secondary support plates 12, and the two secondary support plates 12 are respectively located on opposite sides of the support platform 112. Connecting holes 121 are formed on both of the two secondary support plates 12, and the two secondary support plates 12 can be connected through the connecting holes 121. When this tool is not needed for rescue, rotate the two secondary support plates 12 towards the support platform 112 until they can no longer rotate, and then use a component such as a rope to pass through the two connecting holes 121 to connect the two secondary support plates 12, reducing the volume of the entire support plow head 1 and facilitating carrying and placement. Connecting the two secondary support plates 12 can prevent the two secondary support plates 12 from opening during the movement of this tool, increasing the occupied space and thus affecting carrying and placement.

[0050] Furthermore, when there are two secondary support plates 12, three top blocks 13 are spaced apart. The three top blocks 13 correspond one-to-one to the main support plate 11 and the two secondary support plates 12. The multiple top blocks 13 are respectively arranged on the main support plate 11 and the two secondary support plates 12, enabling this device to penetrate into the soil simultaneously from three positions, shortening the time for this tool to penetrate into the soil and increasing the stability of this device.

[0051] In some embodiments, the rescue tool further includes a first pin shaft 7. A pin shaft hole 1121 is formed on the side wall of the support platform 112. A convex block 122 that cooperates with the pin shaft hole 1121 is provided on the side wall of the secondary support plate 12 close to the support platform 112. The convex block 122 is rotatably connected to the side wall of the pin shaft hole 1121 through the first pin shaft 7.

[0052] Specifically, the secondary support plate 12 realizes the rotational connection with the support platform 112 through the cooperation of the first pin shaft 7, the pin shaft hole 1121, and the convex block 122.

[0053] Among them, a plurality of the pin shafts holes 1121 are spaced apart on the side wall of the support platform 112, and a plurality of the bumps 122 are provided at intervals on the side wall of the secondary support plate 12 close to the support platform 112, and the pin shafts holes 1121 and the bumps 122 correspond to each other one by one.

[0054] Further, the plurality of the pin shafts holes 1121 are evenly distributed. Since there are a plurality of evenly distributed pin shafts holes 1121, the shear stress is prevented from concentrating at one place, thereby increasing the reliability of the tool.

[0055] In some embodiments, two second shaft seats 1122 are provided at intervals on the top of the support platform 112, a second pin shaft 6 is rotatably provided between the two second shaft seats 1122, and the first rotating end 51 of the pull rod 5 is rotatably connected to the second shaft seat 1122 through the second pin shaft 6.

[0056] Specifically, the pull rod 5 is located between the two second shaft seats 1122, and the two second shaft seats 1122 can limit the pull rod 5 from both sides, preventing the position of the pull rod 5 from shifting during the swinging process, resulting in device instability.

[0057] In some embodiments, a third shaft seat 1123 is further provided on the top of the support platform 112, a third pin shaft 8 is rotatably penetrated through the third shaft seat 1123, and the two ends of the third pin shaft 8 correspond to and are rotatably connected to the support ends 32 of the two connecting rods 3 respectively.

[0058] Specifically, the two connecting rods 3 are rotatably connected to the third shaft seat 1123 through the third pin shaft 8 at the same time, so that the rotation of the two connecting rods 3 is synchronous and stable, which is beneficial to the stability of the device.

[0059] In some embodiments, the pull rod 5 has a structure of "big at both ends and thin in the middle", that is, the cross-sectional areas of the first rotating end 51 and the second rotating end 52 of the pull rod 5 are larger than the cross-sectional area of the middle part of the pull rod 5. The structure of "big at both ends and thin in the middle" can prevent interference between the pull rod 5 and the third shaft seat 1123, and at the same time ensure that the pull rod 5 has a larger rotation angle, so that the pull rod 5 applies a greater force to the support plowshare 1, thereby shortening the rescue time.

[0060] In some embodiments, for the part where the control rod 4 is connected to the connecting rod 3, grooves are opened on both sides corresponding to the two connecting rods 3 at this part. These grooves prevent the control rod 4 from interfering with the connecting rod 3 during the swinging process, thereby preventing the entire tool from working.
