DETAILED DESCRIPTION

[0027] ​The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1 - Figure 7 As shown: A pet leash with explosion-proof locking mechanism includes a housing 1, a top cover 2 mounted on the top of the housing 1, a drive motor 3 mounted on the side of the top cover 2, a worm gear 11 connected to the output end of the drive motor 3, a worm wheel 12 meshing with the side end of the worm gear 11, an explosion-proof locking assembly 8 connected to the bottom center end of the worm wheel 12, a locking structure assembly 7 mounted on the side of the housing 1, an auxiliary explosion-proof locking assembly 10 mounted on the bottom of the housing 1, and a leash adjustment assembly 9 mounted inside the housing 1; the explosion-proof locking assembly 8 includes a reinforcing connector 81, a slotted disc fastened to the bottom of the reinforcing connector 81, and the slotted disc... The surface of the plate is provided with equal-spaced sliding dovetail grooves 82. There is an installation space at the connection end of the reinforcing connector 81 and the slotted plate. A spiral groove flat plate 83 is installed inside the installation space. The spiral groove flat plate 83 is located in the rotating groove opened on the inner wall surface of the reinforcing connector 81 to form a rotating connection. A dovetail slider 85 is slidably connected inside the sliding dovetail groove 82. The top of the dovetail slider 85 is slidably connected in the spiral groove of the spiral groove flat plate 83. A reinforcing rope end 86 is fastened to the bottom of the dovetail slider 85. A limit block 87 is fastened to the bottom of the reinforcing rope end 86. A connecting shaft 84 is installed at the axial end of the slotted plate.

[0029] according to Figure 2 , Figure 5 and Figure 7As shown, the auxiliary anti-explosion impact assembly 10 includes a bottom groove disc 101, which is tightly installed on the inner bottom end surface of the shell 1, and a cross sliding groove table 102 is arranged in the center of the bottom groove disc 101. The inner part of the cross sliding groove table 102 is slidably connected with a sliding buffer blocking rod 106. The top part of the sliding buffer blocking rod 106 is slidably located in the sliding dovetail groove 82 and the side of the dovetail sliding block 85. When a sudden impact force is applied, the sliding buffer blocking rod 106 will slide in the sliding groove of the cross sliding groove table 102, and the impact force will be absorbed by the sliding of the sliding buffer blocking rod 106. The top part of the sliding buffer blocking rod 106 is slidably located in the sliding dovetail groove 82, so that the sliding distance of the dovetail sliding block 85 can be limited. When the dovetail sliding block 85 suddenly reaches its trigger position, the sliding buffer blocking rod 106 in the cross sliding groove table 102 is slid, and the impact force is dispersed in multiple directions. The dispersion of the impact force in a single direction is reduced. The design of the sliding dovetail groove 82 and the dovetail sliding block 85 allows the sliding buffer blocking rod 106 to slide not only along the cross sliding groove table 102 but also on the side of the dovetail sliding block 85, further increasing the degree of freedom of sliding, thereby better absorbing and dispersing the impact force and reducing the impact feeling of the pet leash when suddenly pulled, protecting the safety of the pet and the user.

Four groups of rigid arc rods 105 are rotatably connected to the circumferential side of the rotating table 104. The side end of the rigid arc rod 105 is tightly connected with the side surface of the sliding buffer blocking rod 106. Then the rigid arc rod 105 transmits the force of the sliding buffer blocking rod 106 to the rotating table 104. The rotating table 104 further disperses the impact force by rotating. When the rotating table 104 is impacted, it will rotate and disperse the impact force to the four rigid arc rods 105 in four directions through its rotating motion. The arc design of the rigid arc rod 105 allows the force to be transmitted along the arc trajectory, further dispersing the impact force.
