Description

Technical Field

[0001] This utility model relates to the field of electric winch technology, specifically to an electric winch hook. Background Technology

[0002] The electric winch hook is one of the key components of an electric winch. Electric winch hooks are usually made of high-strength steel. The shape and size of the hook are designed according to the specifications of the electric winch and the application scenario. When connecting the cable or sling, ensure that the hook is correctly aligned and securely locked. Avoid using the hook under overload or improper conditions to prevent damage or safety accidents. Electric winch hooks are widely used in many fields such as off-road, rescue, hoisting operations and daily handling.

[0003] For example, Chinese patent CN217708402U, entitled "An Electric Winch Device," includes a bracket with a winch shaft mounted on it. Several cable reels are rotatably mounted on the winch shaft. At one end of the bracket, a drive wheel is connected to the end of the winch shaft. The device also includes a motor, whose output shaft is connected to the drive wheel via a drive wheel. The cable reels are further equipped with a radial fixing device that can be connected to or separated from the winch shaft. This radial fixing device includes a limiting base fixedly mounted on the side of the cable reel, with a fixing pin slidably mounted on the limiting base. The winch shaft has a fixing pin hole, and the end of the fixing pin is detachably inserted into the fixing pin hole. The winch shaft also includes shaft-holding rings mounted on both sides of the cable reels to limit their axial position.

[0004] While the existing technology can enable the use of electric winch hooks, in practical applications, the hook and cable are not easy to assemble and disassemble. The hook and cable are fixed with bolts and nuts, which means that the bolts and nuts need to be removed from the hook when replacing it, thus increasing the complexity of hook assembly and disassembly. On the other hand, the connection between the hook and the cable is difficult to rotate. Usually, the connection between the hook and the cable is fixed, which causes the connection to be subjected to continuous shear and torsional forces, thus aggravating the wear of the connector or the cable. Therefore, it does not meet the current requirements. To address this, we propose an electric winch hook. Utility Model Content

[0005] The purpose of this utility model is to provide an electric winch hook to solve the problems mentioned in the background art, such as the inconvenience of assembling and disassembling the hook and the steel cable, and the difficulty in rotating the connection between the hook and the steel cable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric winch hook, comprising a hook body, an installation cavity provided at the middle position of the upper part of the hook body, the installation cavity having an open structure, an installation seat provided inside the installation cavity, and through holes provided inside the installation seat and both sides of the upper part of the hook body, the through holes having a through structure, and the through holes on the hook body corresponding to the through holes on the installation seat, an insertion rod provided on one side of the outer side of the hook body, one end of the insertion rod extending through the through hole to the outer side of the other side of the hook body, and the installation seat being rotatably connected to the insertion rod, a snap-fit ​​groove provided on the outer side of one end of the insertion rod, the snap-fit ​​groove having an annular structure, a snap-fit ​​spring provided inside the snap-fit ​​groove, the snap-fit ​​spring contacting the side wall of the hook body.

[0007] Preferably, a rotating seat is provided above the mounting base, and a rotating cavity is provided at the lower end of the rotating seat. The lower end of the rotating cavity is an open structure, and a steel cable is fixedly provided at the upper end of the rotating seat.

[0008] Preferably, a connecting seat is fixedly provided at the upper end of the mounting base, the upper end of the connecting seat extends into the interior of the rotating cavity, and the connecting seat is rotatably connected to the rotating base.

[0009] Preferably, a fixed base is fixedly provided on the lower side of one side of the hook body, and a rotating rod is fixedly provided inside the fixed base. The front and rear ends of the rotating rod extend to the outside of the fixed base, and locking plates are fixedly provided at the front and rear ends of the rotating rod. The locking plates are rotatably connected to the rotating rod.

[0010] Preferably, a torsion spring is provided on the outside of the rotating rod located between the locking plate and the fixed seat, and the two ends of the torsion spring are fixedly connected to the locking plate and the fixed seat respectively.

[0011] Preferably, a second rubber pad is fixedly provided on the side of the locking plate near the hook body, and the second rubber pad is bonded and fixed to the locking plate by a polymer adhesive.

[0012] Preferably, a first rubber pad is provided on the lower end face of the hook body, the first rubber pad is fixed to the hook body by a polymer adhesive, and one side of the locking plate is in contact with the first rubber pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model allows for quick assembly and disassembly of the mounting base via the insert rod and the snap ring. When replacing the hook body, the operator first uses a tool to expand the snap ring so that it disengages from the snap-fit ​​groove. Then, the snap ring is removed from the insert rod. At this time, the operator pulls the insert rod out of the through hole to release the fixing of the mounting base. Then, the hook body is separated from the mounting base. When installing the hook body, the operator first aligns the mounting base with the opening of the mounting cavity and inserts it into the mounting cavity until the mounting base is moved to the appropriate position so that the mounting base corresponds to the position of the through hole on the hook body. At this time, the insert rod is reinserted into the through hole, and the snap ring is reinstalled into the snap-fit ​​groove. The contact between the snap ring and the side wall of the hook body makes the insert rod snap-fit ​​and fixed on the hook body, thereby improving the convenience of assembling and disassembling the hook body and the steel cable.

[0015] (2) This utility model allows the hook body to rotate through the rotating cavity and rotating seat. When hoisting goods, the operator first rotates the hook body according to the position of the goods, so that the connecting seat on the hook body rotates inside the rotating cavity until the hook body is adjusted to a suitable angle before the goods are fixed. During the lifting process of the goods, the mounting seat will rotate outside the plug rod until the center of gravity of the goods is adjusted to be parallel to the steel cable. The connecting seat and mounting seat enable the steel cable to move more smoothly when under force, reduce unnecessary friction, and thus extend the service life of the steel cable and the hook body.

[0016] (3) The present invention provides a buffer at the connection between the goods and the hook body through the first rubber pad and the second rubber pad. When the hook body connects the goods, the upper end of the goods is first squeezed against the locking plate. At this time, the locking plate rotates counterclockwise, and the torsion spring is in a compressed state until the upper end of the goods is hung on the hook body and the upper end of the goods contacts the first rubber pad. At this time, the goods are separated from the locking plate, the torsion spring is reset, and the force generated by the reset of the torsion spring pushes the locking plate to rotate clockwise until one side of the locking plate contacts the hook body, and the first rubber pad at the contact part of the locking plate and the hook body is squeezed. The first rubber pad and the second rubber pad can effectively reduce the friction between the goods and the hook body, reduce the wear that may occur during the hoisting process, and thus reduce the risk of damage to the goods.

The locking plate 9 is rotatably connected to the rotating rod 13. A torsion spring 17 is provided on the outside of the rotating rod 13 between the locking plate 9 and the fixed seat 10. The two ends of the torsion spring 17 are fixedly connected to the locking plate 9 and the fixed seat 10, respectively.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The mounting cavity 2 is provided with a mounting base 6. The mounting base 6 and the upper sides of the hook body 1 are both provided with through holes 16. The through holes 16 are through structures, and the positions of the through holes 16 on the hook body 1 and the through holes 16 on the mounting base 6 are corresponding. A plug rod 3 is provided on one side of the hook body 1. One end of the plug rod 3 extends through the through hole 16 to the outside of the other side of the hook body 1. The mounting base 6 is rotatably connected to the plug rod 3. A snap-fit ​​groove 4 is provided on the outside of one end of the plug rod 3. The snap-fit ​​groove 4 is a ring structure. A snap spring 5 is provided inside the snap-fit ​​groove 4. The snap spring 5 contacts the side wall of the hook body 1, which facilitates the assembly and disassembly of the hook body 1 through the snap-fit ​​groove 4 and the snap spring 5.

[0025] Please see Figure 1 and Figure 2 A rotating seat 8 is provided above the mounting base 6. A rotating cavity 14 is provided at the lower end of the rotating seat 8. The lower end of the rotating cavity 14 is an open structure. A steel cable 7 is fixedly provided at the upper end of the rotating seat 8. A connecting seat 15 is fixedly provided at the upper end of the mounting base 6. The upper end of the connecting seat 15 extends into the interior of the rotating cavity 14, and the connecting seat 15 is rotatably connected to the rotating seat 8, so as to facilitate the rotation of the hook body 1 through the connecting seat 15.

[0026] Please see Figure 1 and Figure 2 A second rubber pad 12 is fixedly provided on the side of the locking plate 9 near the hook body 1. The second rubber pad 12 is bonded to the locking plate 9 with a polymer adhesive. A first rubber pad 11 is provided on the lower end face inside the hook body 1. The first rubber pad 11 is bonded to the hook body 1 with a polymer adhesive, and one side of the locking plate 9 is in contact with the first rubber pad 11, so as to provide cushioning for the connection between the goods and the hook body 1 through the first rubber pad 11 and the second rubber pad 12.

[0027] Working principle: When replacing the hook body 1, the operator first uses a tool to expand the retaining spring 5, causing it to disengage from the locking groove 4. Then, the retaining spring 5 is removed from the insert rod 3. At this time, the operator pulls the insert rod 3 out of the through hole 16, releasing the fixing of the mounting base 6. Then, the hook body 1 is separated from the mounting base 6. When installing the hook body 1, the mounting base 6 is first aligned with the opening of the mounting cavity 2 and inserted into the mounting cavity 2 until the mounting base 6 is moved to the appropriate position, so that the mounting base 6 corresponds to the position of the through hole 16 on the hook body 1. At this time, the insert rod 3 is reinserted into the through hole 16, and the retaining spring 5 is reinstalled into the locking groove 4. The contact between the retaining spring 5 and the side wall of the hook body 1 causes the insert rod 3 to be locked onto the hook body 1. When the hook body 1 connects to the goods, the upper end of the goods is first pressed against the locking plate 9. At this time, the locking plate 9 rotates counterclockwise, and the torsion spring 17 is compressed until the upper end of the cargo is hooked onto the hook body 1 and the upper end of the cargo contacts the first rubber pad 11. At this time, the cargo is separated from the locking plate 9, and the torsion spring 17 resets. The force generated by the reset of the torsion spring 17 pushes the locking plate 9 to rotate clockwise until one side of the locking plate 9 contacts the hook body 1, and the first rubber pad 11 at the contact point between the locking plate 9 and the hook body 1 is squeezed. When hoisting cargo, the operator first rotates the hook body 1 according to the position of the cargo, so that the connecting seat 15 on the hook body 1 rotates inside the rotating cavity 14 until the hook body 1 is adjusted to a suitable angle before the cargo is fixed. During the lifting process of the cargo, the mounting seat 6 will rotate outside the insertion rod 3 until the center of gravity of the cargo is adjusted to be parallel to the steel cable 7.
