Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 4, the dog leash assembly comprises a leash 1 and a locking piece 2, and further comprises a support piece 3 and a thread cover 4 with a hollow structure, wherein one end of the leash 1 is bent to form an S-shaped section 11, the thread cover 4 is sleeved on the S-shaped section 11, two bent portions 12 of the S-shaped section 11 are exposed from two ends of the thread cover 4 respectively, a part of the locking piece 2 is limited in one of the bent portions 12, and a part of the support piece 3 is limited in the other bent portion 12.

From the above description, the beneficial effects of the present invention are: the joint of the dog leash pulling assembly and the locking piece 2 does not need to use a sewing thread, so that the damage of the sewing thread to the rope belt 1 after the dog leash pulling assembly is used for a long time can be avoided, and the service life of the dog leash pulling assembly can be prolonged; in the dog leash assembly, the leash 1, the support piece 3, the thread sleeve 4 and the locking piece 2 form a self-locking structure, and the end head/the locking piece 2 of the S-shaped section 11 can be pulled to realize firm connection of the four, so that the situation that the locking piece 2 is accidentally separated from the leash 1 is effectively avoided, and the structural stability of the dog leash assembly is greatly improved; in addition, as sewing threads do not need to be sewn, the dog leash assembly is higher in manufacturing efficiency, and the manufacturing cost of the dog leash assembly is favorably reduced.

Furthermore, one end of the wire sleeve 4 close to the supporting member 3 is provided with a notch 41 for accommodating at least a part of the supporting member 3, and the notch 41 is communicated with the hollow structure.

As can be seen from the above description, the gap 41 can serve to accommodate and limit the supporting member 3.

Furthermore, at least one side of the opening of the gap 41 is provided with a guide surface 42.

As can be seen from the above description, the guiding surface 42 is arranged to allow at least a portion of the support member 3 to slide smoothly into the gap 41. The guide surface 42 may be a curved surface or a slope.

Further, the support member 3 includes a rod portion 31, and two ends of the rod portion 31 are respectively supported at two ends of the gap 41.

As can be seen from the above description, the two ends of the supporting member 3 are respectively supported on the thread sleeves 4, so that the S-shaped section 11 of the rope belt 1 can be prevented from being accidentally dissipated, and the structural stability of the dog leash assembly is further ensured.

Further, the support 3 is shaped like a frame, and the rod 31 is a part of the frame; one end of the S-shaped section 11 penetrates the frame.

It can be known from the above description that above-mentioned setting can avoid support piece 3 accident to break away from fag end 1 effectively, does benefit to the structural stability who further improves dog leash subassembly. Moreover, one end of the S-shaped section 11 penetrates through the frame body, so that the dislocation degree of the S-shaped section 11 and other areas of the rope belt 1 can be greatly improved, and the rope belt 1 and the locking piece 2 are more easily locked and connected at the position of the thread sleeve 4.

Further, the bottom of the notch 41 is provided with an accommodating area 43, and the diameter of the accommodating area 43 is larger than the width of the notch 41.

From the above description, the accommodating area 43 can clamp the supporting member 3, so as to reduce the probability that the supporting member 3 is separated from the rope belt 1, and further improve the structural stability of the dog leash assembly.

Further, the thickness of the wire cover 4 near the end of the supporting member 3 is larger than the thickness of the wire cover 4 near the end of the locking member 2.

As can be seen from the above description, the thickness of the wall of the notch 41 can be ensured, and the manufacturing material consumption of the wire sleeve 4 can be reduced. The notch 41 with proper thickness can simultaneously take strength and toughness into consideration, so that the support 3 and the area of the rope belt 1 wound on the support 3 can be better clamped.

Further, a retaining block 44 is arranged on the inner wall of the wire sleeve 4.

As can be seen from the above description, the arrangement of the retaining block 44 can prevent the end of the leash 1 from accidentally separating from the sleeve 4 so that the S-shaped section 11 dissipates, which is beneficial to further improving the structural stability of the dog leash assembly.

Further, the retaining block 44 is formed in a wedge shape, and the height of the wedge is gradually increased from the end near the supporting member 3 to the end near the locking member 2.

As can be seen from the above description, the retaining block 44 has a simple structure and is easy to process and can be formed during the injection molding of the wire cover 4.

Furthermore, the end of the hollow structure far away from the support 3 is provided with a caliber change area 45, and the caliber of the end of the caliber change area 45 far away from the locking piece 2 is smaller than that of the end thereof far away from the support 3.

As can be seen from the above description, the closer the two ends of the bending part 12 wound on the locking part 2 are to the locking part 2, the larger the distance between the two ends is, when the distance between the locking part 2 and the wire sleeve 4 is shortened to the limit, the two ends of the bending part 12 can directly or indirectly press against the inner wall of the aperture change area 45 to form a static friction force, thereby more effectively preventing the rope belt 1 from separating from the wire sleeve 4 to dissipate the S-shaped section 11, and further improving the structural stability of the dog leash assembly.

Example one

Referring to fig. 1 to 4, a first embodiment of the present invention is: dog leash comprises a handheld main body (not shown in the figure) and a dog leash component which are connected, as shown in the figure 1, the dog leash component comprises a leash 1, a locking piece 2, a supporting piece 3 and a thread sleeve 4 with a hollow structure, one end of the leash 1 is bent to form an S-shaped section 11, the other end of the leash 1 is connected to the handheld main body, the thread sleeve 4 is sleeved on the S-shaped section 11, two bent parts 12 of the S-shaped section 11 are respectively exposed from two ends of the thread sleeve 4, one part of the locking piece 2 is limited in one of the bent parts 12, and one part of the supporting piece 3 is limited in the other of the bent parts 12. In this embodiment, the rope 1 is a flat belt, and the locking member 2 is a dog buckle.

Referring to fig. 1 to 4, a gap 41 for accommodating at least a portion of the supporting member 3 is disposed at one end of the wire sleeve 4 close to the supporting member 3, and the gap 41 is communicated with the hollow structure.
