Description

Technical Field

[0001] The invention relates to the technical field of winch devices, in particular to a Russian-style multifunctional winch with high efficiency and labor-saving. Background Art

[0002] A manual winch is a mechanical device that uses human power to drive the winch drum to achieve traction, lifting or dragging of heavy objects. It is of irreplaceable importance in many scenarios. In outdoor adventures, off-road activities or natural disaster scenarios, when vehicles or equipment are trapped, the manual winch can be operated manually to achieve self-rescue or mutual rescue. Especially when used in factories, when it is necessary to move small and medium-sized equipment, adjust the position of components or lift heavy objects, the manual winch can be used in narrow spaces that cranes or electric equipment cannot enter due to its small size and flexible operation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figures 1-10 As shown, the embodiment of the present invention provides a high-efficiency and labor-saving Russian multifunctional winch, comprising: a base plate 1 with an opening on one side and a U-shaped structure, a movable plate 2, a winch component 3, an elastic lock 6 and an elastic lock 2 8, and an arm 5. Specifically, the openings of the base plate 1 and the movable plate 2 are arranged opposite to each other, the movable plate 2 is sleeved on the base plate 1, and the movable plate 2 is rotatably connected to the base plate 1; the winch component 3 rotates on the base plate 1, and a traction rope 4 is wound on the winch component; the elastic lock 1 6 and the elastic lock 2 8 are respectively arranged on the movable plate 2 and the base plate 1, and the elastic lock 1 6 and the elastic lock 2 8 are both used to lock the winch component 3 in one direction; the arm 5 is connected to the side wall of the movable plate 2 away from the base plate 1, and The arm 5 has a telescopic structure; when in use, by setting a base plate 1 and a movable plate 2 that are rotatably connected to each other, according to the external structure of the base plate 1 and the movable plate 2, under the drive of the arm 5, the base plate 1 and the movable plate 2 can be uniformly stressed at the rotational connection, changing the existing single-sided stress to double-sided stress, so that the tension is located in the middle position of the device, achieving the purpose of uniform stress, increasing the service life of the device, and avoiding the occurrence of installation hazards. Under the action of the elastic lock buckle 1 6 and the elastic lock buckle 2 8, the winch component 3 is locked, and at the same time, the elastic lock buckle 1 6 and the elastic lock buckle 2 8 can be used to quickly contact the locked state of the winch component 3, so that it can achieve the purpose of quickly releasing the traction rope 4.

[0021] Circular rotating bases 7 are fixedly connected to the outer walls on both sides of the base plate 1, and the inner walls on both sides of the movable plate 2 are rotatably connected to the rotating bases 7, and the interior of the base plate 1 is connected to the interior of the movable plate 2 to form a winding channel 9; the winch member 3 is located in the winding channel 9, and the winding channel 9 has a certain height so that it will not touch the winch member 3 when in use. When in use, the base plate 1 can be fixed to the fixed structure first, and then the movable plate 2 can be rotated to make the movable plate 2 move back and forth in a circle on the base plate 1.

[0022] Among them, Figure 2 as well as Figure 8As shown, the winch component 3 includes a rotating shaft 31 and a ratchet disc 32; wherein, the rotating shaft 31 is rotatably connected to the base, the axis of the rotating shaft 31 is collinear with the axis of the rotating base 7, the ratchet disc 32 is longitudinally connected to the rotating shaft 31, and its central axis is collinear with the central axis of the rotating shaft 31; the rotating shaft 31 is also connected to a protective disc 33, and a winding groove 34 is formed between the protective disc 33 and the ratchet disc 32, and the winding groove 34 is suitable for winding and accommodating the traction rope 4. When in use, the rotating shaft 31 is rotated to drive the ratchet disc 32 and the protective disc 33 to rotate, so that the traction rope 4 can be wound.

[0023] A plurality of slots 35 are provided on the side wall of the ratchet disc 32, and the slots 35 are equidistantly arranged around the central axis of the ratchet disc 32; in order to facilitate stabilizing the traction rope 4 on the ratchet disc 32, as shown in FIG. Figure 8 As shown, a plurality of fixing holes 36 are axially opened on the ratchet disk 32, and the plurality of fixing holes 36 are equidistantly arranged around the central axis of the ratchet disk 32. The fixing holes 36 are internally threadedly connected with fixing bolts 37, and the fixing bolts 37 are provided with through holes 38 suitable for the passage of the traction rope 4. A suitable winding method is selected to connect the end of the traction rope 4 to the ratchet disk 32, and finally the end of the traction rope 4 passes through the through hole 38 on the fixing bolt 37. Finally, a nut is used to tighten the fixing bolt 37 and fix it on the fixing hole 36 of the ratchet disk 32, thereby completing the fixation of the traction rope 4.

[0024] Further, such as Figure 5 as well as Figure 7 As shown, the elastic lock buckle 6 includes a bayonet 61, a connecting column 62, a fixing tube 63, and a spring 64; wherein, the end of the bayonet 61 is movably engaged with the slot 35, and the connecting column 62 is longitudinally connected to the bayonet 61; a penetrating device slot is provided on the movable plate 2, and the fixing tube 63 is connected to the device slot, and the end of the connecting column 62 away from the bayonet 61 passes through the fixing tube 63 and is slidably connected to the fixing tube 63, and the spring 64 is sleeved on the outside of the connecting column 62, and the two ends of the spring 64 are respectively connected to the fixing tube 63 and the bayonet 61. When in use, the movable plate 2 is rotated to drive the bayonet 61 to move accordingly. When the bayonet 61 moves in a circular motion, its end will be pushed by the slot 35, thereby causing the bayonet 61 and the connecting column 62 to slide longitudinally on the fixing tube 63, and under the action of the spring 64, the bayonet 61 can return to its initial position after each sliding; In order to facilitate the release of the engagement state of the bayonet 61 with the bayonet slot 35, the elastic lock buckle 6 further includes a guide tube 65 connected to the end of the fixing tube 63 away from the bayonet 61, a drawing tube 66 slidably connected to the inside of the guide tube 65, a threaded rod 28 connected to the drawing tube 66, and a threaded block 67 rotatably connected to the guide tube 65; wherein, one end of the connecting column 62 passes through the drawing tube 66 and extends to the inside thereof, and is provided with an annular protrusion 68, the annular protrusion 68 is slidably connected to the inside of the drawing tube 66, and the threaded rod 28 is away from the inside of the drawing tube 66. One end of the pulling tube 66 passes through the threaded block 67 and is threadedly connected to the threaded block 67. A hand ring 69 is connected to the outer wall of the threaded block 67. By rotating the threaded block 67, the pulling tube 66 can be driven to move in the guide tube 65. After the pulling tube 66 moves a certain distance, its interior will conflict with the annular protrusion 68 on the connecting column 62, thereby driving the connecting column 62 to move synchronously, and finally driving the pin 1 61 to move away from the slot 35. At this time, the engagement of the pin 1 61 with the slot 35 is released.

[0025] Then, if Figure 4 as well as Figure 9 As shown, the elastic lock buckle 2 8 includes a second bayonet pin 81, a device frame 82, a hinged base 83, a rotating shaft 84, a second spring 85 and a spring plate 86; wherein the device frame 82 is connected to the base plate 1, the hinged base 83 is connected to the device frame 82, and the rotating shaft 84 is rotatably connected to the hinged base 83, one end of the second bayonet pin 81 is movably engaged with the slot 35, and the other end of the second bayonet pin 81 is connected to the rotating shaft 84; the spring plate 86 is connected to the device frame 82, and the two ends of the second spring 85 are respectively connected to the second bayonet pin 81 and the spring plate 86; an anti-collision plate 87 is connected to the device frame 82 to prevent the movable plate 2 from touching the elastic lock buckle 2 8; when the elastic lock buckle 2 8 is in use, the movable plate 2 is rotated, and the end of its second bayonet pin 81 will be pushed by the slot 35, so that the second bayonet pin 81 is sequentially engaged with the next slot 35, and under the action of the second spring 85, the second bayonet pin 81 can return to its initial position after passing through each slot 35; In order to facilitate the release of the engagement of the second latch pin 81 with the latch slot 35, Figure 10As shown, the elastic lock buckle 2 8 also includes an eccentric plate 10, a worm wheel 11, a worm 12 and a hand wheel 13; wherein the eccentric plate 10 is connected to one end of the rotating shaft 84 and is on the same axis as the rotating shaft 84, the worm wheel 11 and the worm 12 are respectively rotatably connected to the device frame 82, the worm wheel 11 and the worm 12 are screwed together, and the central axis of the worm wheel 11 is collinear with the central axis of the eccentric plate 10, and a distance is left between the eccentric plate 10 and the worm wheel 11, and an eccentric protrusion 16 is provided on the side wall of the eccentric plate 10 close to the worm wheel 11, and the side wall of the worm wheel 11 close to the eccentric plate 10 is provided with a eccentric protrusion 16. A toggle post 15 is connected to the wall. By rotating the worm 12, the worm wheel 11 can be driven to rotate. After the worm wheel 11 rotates to a certain angle, the toggle post 15 will touch the eccentric protrusion 16, and drive the eccentric protrusion 16 and the eccentric plate 10 to rotate. Finally, the eccentric plate 10 drives the rotating shaft 84 to rotate. The rotation of the rotating shaft 84 can drive the second bayonet 81 to disengage from the slot 35, so that it no longer forms a locked state with the slot 35. Because the worm wheel 11 and the worm 12 are non-reversible rotation structures, they can be in a self-locking state after the second bayonet 81 is released from the engagement state of the slot 35.

[0026] like Figure 1 、 Figure 2 as well as Figure 6 As shown, the arm 5 has a telescopic structure, which can change the size of the force arm during use. At the same time, the length of the arm 5 can be changed according to the actual use scenario to improve practicality. Specifically, in order to achieve the telescopic effect, it is composed of a power rod 17 and a power rod 2 18 slidably connected to the power rod 1 17. The power rod 1 17 is a hollow structure and has an opening at one end. The power rod 17 is connected to the movable plate 2, and a plurality of clamping holes 19 are axially equidistantly provided on the power rod; a sliding groove 20 is radially provided on the power rod 2 18, and a pin 21 is slidably connected to the sliding groove 20, and an inclined surface 27 is provided at the end of the pin 21. One end of the pin 21 having the inclined surface 27 is movably clamped with the clamping hole 19, and a spring 3 22 is connected between the sliding groove 20 and the pin 21. The power rod 2 18 can change the size of the force arm by telescoping on the power rod 1 17.

[0027] Secondly, in order to quickly release the locking relationship between the pin block and the locking hole 19, an axial long groove 23 is opened on the power rod 17, and a ring plate 24 is connected to the outer wall of the power rod 2 18 through a connecting strip. The connecting strip is suitable for passing through the long groove 23, and a contraction spring 25 is connected to the ring plate 24. The end of the contraction spring 25 away from the ring plate 24 has an extrusion ring 26, and one end of the extrusion ring 26 has an inclined surface 27, and is in active contact with the inclined surface 27 of the pin 21. When the extrusion ring 26 slides down, it will squeeze the pin 21, so that the pin 21 retracts into the sliding groove 20. After the pin 21 retracts a certain distance, the inclined surface of its end contacts the side wall of the locking hole 19 on the power rod 1 17. At this time, pulling the power rod 2 18 can contact the side wall of the locking hole 19 to push the pin 21 to continue to retract into the sliding groove 20. At this time, the power rod 2 18 can be moved on the power rod 1 17.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
