Referring to fig. 1 and 2, a trailer hook 100 according to an embodiment of the present application includes a towing member 10 and a mounting member 20. The pulling member 10 includes a connecting portion 11 and a pulling portion 12 connected to the connecting portion 11, and the pulling portion 12 is disposed obliquely with respect to the connecting portion 11. The mounting part 20 comprises a first mounting part 21 and a second mounting part 22 connected with the first mounting part 21, the first mounting part 21 is fixedly connected with the connecting part 11, the second mounting part 22 is fixedly connected with the traction part 12, and one end, far away from the connecting part 11, of the traction part 12 protrudes out of the second mounting part 22.

In this manner, the trailer hook 100 according to the embodiment of the present application has a simple structure, and a portion of the towing part 12 protrudes from the second mounting part 22 to form the towing hole 30, and a towing rope can be used to pass through the towing hole 30 to tow the vehicle. The fixed connection of the mounting member 20 to the coupling and draft portions 11, 12 of the draft gear 10 increases the overall stiffness and load carrying capacity of the draft gear 100 such that the draft gear 100 is not susceptible to deformation when used to draft a vehicle.

Specifically, the tow hook 100 may be applied to a vehicle, the tow hook 100 may be fixed to the vehicle by the first mounting portion 21 and the connecting portion 11, a tow rope or a tow hook may be fixed to the tow hook 100 through the towing portion 12, and the vehicle may be towed by another vehicle or by another vehicle by pulling the tow rope or the tow hook.

More specifically, the towing member 10 and the mounting member 20 are connected together and fixed to a side member of the vehicle. First installation department 21 and the second installation department 22 of installed part 20 respectively with connecting portion 11 and the fixed part fixed connection of pulling piece 10 to strengthen the connecting portion 11 and the fixed part of pulling piece 10, make connecting portion 11 and fixed part non-deformable, so, installed part 20 can play reinforced effect, make tow hook 100 non-deformable when towing vehicle, thereby promote the bearing capacity of tow hook 100.

The first mounting portion 21 and the connecting portion 11 may be fixedly connected by welding, and the second mounting portion 22 and the traction portion 12 may be fixedly connected by welding.

Further, an end of the towing part 12 away from the connecting part 11 protrudes from the second mounting part 22 to form a towing hole 30, and when the towing hook 100 is used to tow a vehicle, a towing rope or a towing hook can be used to pass through the towing hole 30, and the towing rope or the towing hook can be pulled to move the vehicle. The traction part 12 is obliquely arranged relative to the connecting part 11, so that the traction rope or the traction hook is more labor-saving when the vehicle is dragged, and the efficiency of dragging the vehicle is improved.

During the towing of a vehicle using the tow hook 100 and a tow rope or a tow hook, the tow hook 100 is subjected to a large towing force, and thus the tow hook 100 may be made of a high-strength metal material to prevent the tow hook 100 from being broken. The traction part 12 can be a semicircular structure, a U-shaped structure, a V-shaped structure and the like, so that the traction rope or the traction hook is not easy to slide on the traction part 12.

Referring to fig. 1, in some embodiments, the connecting portion 11 includes two connecting rods 111 disposed opposite to each other, and each connecting rod 111 is fixedly connected to the first mounting portion 21. In this manner, the tow hook 100 can be secured to the vehicle by the first mounting portion 21 and the two connecting rods 111.

Specifically, the first mounting portion 21 may be a groove structure, the two connecting rods 111 are parallel and fixed in the groove of the first mounting portion 21 at intervals, and the connecting rods 111 and the first mounting portion 21 may be fixedly connected by welding, so as to prevent the connecting rods 111 from falling from the first mounting portion 21. After the connecting rod 111 is fixed to the first mounting portion 21, the first mounting portion 21 is fixedly connected to the side member of the vehicle. Preferably, the first mounting portion 21 and the longitudinal beam are fixed by bolts, so that the trailer hook 100 can be conveniently mounted and dismounted, and the first mounting portion 21 is not easy to break in the process of towing the vehicle. Of course, in other embodiments, the first mounting portion 21 and the side member may be fixed by welding.

The both ends of traction portion 12 are connected with two connecting rods 111 respectively, and traction portion 12 roughly can be "U" type form, and traction portion 12 protrusion is in second installation department 22 in order to form towing hole 30, and usable haulage rope or tow hook pass towing hole 30, thereby drive the removal of vehicle through pulling haulage rope or tow hook. The second mounting portion 22 may be a groove structure, the pulling portion 12 is fixed in the groove of the second mounting portion 22, and the pulling portion 12 and the second mounting portion 22 may be fixedly connected by welding.

In some embodiments, the coupling portion 11 and the draft portion 12 may be formed as a unitary structure such that the draft gear 10 of the trailer hook 100 is not susceptible to breakage during towing of a vehicle using the trailer hook 100 and a tow rope or a draft hook. In one example, the pulling member 10 is bent from forged steel so that the pulling portion 12 of the pulling member 10 can be substantially "U" shaped, and the pulling portion 12 is disposed obliquely with respect to the connecting portion 11.

It is noted that a bent portion 13 is formed between the connecting portion 11 and the pulling portion 12 so that the pulling portion 12 can be disposed obliquely with respect to the connecting portion 11.

Referring to fig. 1 and 2, in some embodiments, the first mounting portion 21 includes a first bottom wall 211 and a first sidewall 212 connected to an edge of the first bottom wall 211, the second mounting portion 22 includes a second bottom wall 221 and a second sidewall 222 connected to an edge of the second bottom wall 221, the second bottom wall 221 is connected to the first bottom wall 211, the first sidewall 212 is connected to the second sidewall 222, both the first bottom wall 211 and the first sidewall 212 are fixedly connected to the connecting portion 11, and both the second bottom wall 221 and the second sidewall 222 are fixedly connected to the traction portion 12.

In this way, the first bottom wall 211, the first side wall 212, the second bottom wall 221 and the second side wall 222 can reinforce the towing part 10 of the trailer hook 100, improve the bearing capacity of the trailer hook 100, and avoid the deformation of the trailer hook 100 in the process of towing a vehicle by using the trailer hook 100.

In some embodiments, the number of the first side walls 212 and the second side walls 222 is two, two first side walls 212 are spaced apart from each other on two sides of the first bottom wall 211, and two second side walls 222 are spaced apart from each other on two sides of the second bottom wall 221. In this way, the first side wall 212 disposed on both sides of the first bottom wall 211 and the second side wall 222 disposed on both sides of the second bottom wall 221 can protect the towing member 10, and prevent the towing member 10 from slipping off the mounting member 20.

Specifically, the number of the first side walls 212 may be two, the first side walls 212 may be substantially rectangular, the two first side walls 212 are disposed at two sides of the first bottom wall 211 at intervals, the first bottom wall 211 and the two first side walls 212 may enclose a groove shape, the two connecting rods 111 of the connecting portion 11 are respectively fixedly connected with the two first side walls 212, and meanwhile, the two connecting rods 111 are both fixedly connected with the first bottom wall 211.

Similarly, the second side wall 222 may be substantially rectangular, the number of the second side walls 222 may also be two, and two second side walls 222 are disposed at two sides of the second bottom wall 221 at intervals. The pulling part 12 is fixedly connected to the two second side walls 222 and the second bottom wall 221.

It will be appreciated that the mounting member 20 may be a one-piece structure such that the first side wall 212 is continuous with the second side wall 222 such that the first side wall 212 is broken when the tow hook 100 is subjected to excessive towing forces, such as when the angle between the first side wall 212 and the second side wall 222 increases.

Referring to fig. 1 and 2, in some embodiments, the first sidewall 212 and the second sidewall 222 have a connection portion 23, and a first groove 231 is formed at an end of the connection portion 23 away from the first bottom wall 211.

Thus, when the trailer hook 100 is bent and deformed, the first groove 231 is cracked and simultaneously makes a sound to remind a user to replace the trailer hook 100 after the current towing operation is completed.

Specifically, when the towing force applied to the tow hook 100 is too large during towing of a vehicle by the tow hook 100 and a towing rope or a towing hook, the tow hook 100 may be deformed, and more specifically, an included angle between a plane in which the first mounting portion 21 is located and a plane in which the second mounting portion 22 is located is gradually increased, that is, an included angle between the two first side walls 212 and the two second side walls 222 is gradually increased. When the included angle increases to a predetermined value, the first groove 231 between the first sidewall 212 and the second sidewall 222 may crack the first groove 231 and may generate a muffled sound easily perceived by a user.

Thus, the user can know that the current trailer hook 100 has been deformed through the cracking condition of the first groove 231 and the sound generated by the first groove, and the user can replace the new trailer hook 100 in time, so that the influence on the next use is avoided.

Referring to fig. 1 and 2, in some embodiments, a rib 241 is disposed at a joint 24 of the first bottom wall 211 and the second bottom wall 221. Thus, the reinforcing ribs 241 may increase the overall stiffness and load bearing capacity of the trailer hook 100 assembly such that the trailer hook 100 is less susceptible to deformation. The reinforcing ribs 241 may be formed by punching the joint 24 of the first and second bottom walls 211 and 221.

Referring to fig. 1 and 2, in some embodiments, the first bottom wall 211 and the first side wall 212 are both welded and fixed to the connecting portion 11, the second bottom wall 221 and the second side wall 222 are both welded and fixed to the traction portion 12, and the welding seam avoids a joint 24 between the first bottom wall 211 and the second bottom wall 221 and a joint 23 between the first side wall 212 and the second side wall 222.

Therefore, the traction piece 10 can be stably connected with the mounting piece 20, meanwhile, the traction piece 10 and the joint 24 and the joint 23 close to the mounting piece 20 are not welded, and the bending structure of the traction piece 10 can generate a certain space by utilizing different stress deformation degrees of the traction piece 10 and the mounting piece 20, so that the deformation tendency of the trailer hook 100 can be blocked, borne traction force can be decomposed, and a longitudinal beam of a vehicle beam can be protected.

Specifically, the first side wall 212 and the second side wall 222 have a joint 23, the first bottom wall 211 and the second bottom wall 221 have a joint 24, the portions of the two connecting rods 111 of the traction member 10 are fixed to the first side wall 212 and the first bottom wall 211 by welding, the traction portion 12 of the traction member 10 is fixed to the second side wall 222 and the second bottom wall 221 by welding, the bending portion 13 formed between the connecting portion 11 and the traction portion 12 is not welded to the mounting member 20, and the bending portion 13 of the traction member 10 can abut against the joint 23 and the joint 24 of the mounting member 20.

In this way, the stress deformation degree of the joint 23 and the joint 24 of the bending part 13 and the mounting part 20 of the traction piece 10 is different, so that a certain space can be generated between the joint 24 and the joint 23 and the bending part 13, the deformation tendency of the trailer hook 100 can be blocked, the traction force of the trailer hook 100 can be decomposed and borne, and the longitudinal beam of the beam can be protected.

Referring to fig. 1, in some embodiments, an included angle between a plane of the connecting portion 11 and a plane of the pulling portion 12 is consistent with an included angle between a plane of the first bottom wall 211 and a plane of the second bottom wall 221. Like this, draw piece 10 and installed part 20 to be connected, and the angle of bending of installed part 20 is unanimous with the angle of bending of drawing piece 10 for installed part 20 can better protect and draw piece 10, thereby promotes the whole bearing capacity of tow hook 100, makes tow hook 100 difficult production when receiving great traction force warp.

In some embodiments, the angle between the plane of the connecting portion 11 and the plane of the pulling portion 12 is identical to the angle between the plane of the first bottom wall 211 and the plane of the second bottom wall 221, and ranges from 100 ° to 130 °. Therefore, an included angle exists between the plane where the traction part 12 is located and the plane where the longitudinal beam of the vehicle is located, and the traction rope or the traction hook can penetrate through the traction part 12.

Specifically, when the tow hook 100 is fixed to a longitudinal beam of a vehicle, the towing part 12 is disposed obliquely to the connecting part 11, so that a towing rope or a towing hook can be more labor-saving when towing the towing part 12 to tow the vehicle. The included angle can be 100 degrees, 105 degrees, 110 degrees, 120 degrees, 125 degrees, 130 degrees and the like, and when the included angle is smaller than 100 degrees, the traction rope or the traction hook is more strenuous when the vehicle is dragged; when the angle is larger than 130 °, the angle between the plane of the towing part 12 and the plane of the longitudinal beam of the vehicle is too small, and it is difficult for the towing rope or the towing hook to pass through the towing part 12.

Referring to fig. 1 and 2, in some embodiments, an end of the second bottom wall 221 away from the first bottom wall 211 is formed with a second groove 2211. In this manner, when a traction rope or a traction hook is passed through the traction hole 30, the traction rope or the traction hook partially overlaps the second groove 2211, so that abrasion of the traction rope or the traction hook can be reduced.

Referring to fig. 1 and 2, in some embodiments, two connecting rods 111 are connected to the first bottom wall 211, the first bottom wall 211 is provided with through holes 2111, and the through holes 2111 are spaced from the two connecting rods 111. In this way, the fixing member can be used to pass through the through hole 2111 to connect the trailer hook 100 with the vehicle, so that the trailer hook 100 and the vehicle can be conveniently mounted and dismounted, and meanwhile, the first bottom wall 211 is not easy to break in the process of towing the vehicle.

Specifically, the number of the through holes 2111 may be one or more, for example, the number of the through holes 2111 may be one, two, three, or the like, and the number of the fixing members is the same as the number of the through holes 2111. The plurality of fasteners engaged with the through holes 2111 may provide a more secure connection between the trailer hook 100 and the vehicle. In one example, the fastener may be a bolt, and the trailer hook 100 may be secured to a rail of a frame of a vehicle using the bolt through the through hole 2111.

In some embodiments, the number of the through holes 2111 is multiple, the through holes 2111 are spaced apart, and the distance between two adjacent through holes 2111 is in the range of 6-10 mm. In this manner, the risk of the fastener shearing within the through-hole 2111 may be reduced.

Specifically, the distance between two adjacent through holes 2111 may take a value of 6mm, 7mm, 8mm, 9mm, 10mm, or the like. When the distance between two adjacent through holes 2111 is smaller than 6mm, the installation of a plurality of fixing pieces is not convenient due to the small distance; when the distance between two adjacent through holes 2111 is greater than 10mm, in the process of towing the vehicle by using the tow hook 100 and the tow rope or the tow hook, when the towing force borne by the tow hook 100 is large, the fixing piece is easily sheared in the through hole 2111.
