Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the utility model provides a safety restriction protective equipment for urban dogs, which comprises a vest 1, two groups of explosion-proof impact components and a chest fixing band 3.
The vest 1 can be placed on the back of a dog.
Two ends of the chest fixing belt 3 are respectively fixed at the front ends of two side surfaces of the vest 1, and the chest fixing belt 3 can be sleeved under the neck of a dog.
The two groups of anti-explosion components are symmetrically arranged on two side surfaces of the vest 1 respectively.
The bursting disc assembly comprises a front leg retraction strap 21 and a retraction device 22.
The constriction device 22 is arranged on the outside of the side of the vest 1. The two ends of the front leg contraction belt 21 are respectively a fixed end 211 and a contraction end 212. The fixed end 211 is connected to the vest 1 and the contraction end 212 is connected to the contraction device 22. Two front leg contraction belts 21 are respectively sleeved at the root parts of the front legs of the dog.
The contraction device 22 includes a housing 221 and a drum 222.
The shell 221 is hollow and is fixed to the outer surface of the vest 1. The housing 221 has a belt penetration 2211. The drum 222 is rotatably disposed in the housing 221 via a rotating shaft, a bearing, or the like.
The contraction end 212 of the front leg contraction belt 21 extends into the housing 221 from the belt insertion opening 2211 and is fixed to the drum 222. The drum 222 rotates, the front leg contraction belt 21 is wound on the drum 222, the length of the front leg contraction belt 21 exposed to the outside of the housing 221 is shortened, and the shortened front leg contraction belt 21 tightly grips the root of the front leg of the dog, thereby preventing the dog from bursting.
Specifically, one end of the drum 222 is fixedly provided with a drum gear 2221. The retractor 22 also includes a motor 223 and a drive gear 224. The motor 223 is fixed in the housing 221, and an output shaft of the motor 223 is parallel to the drum 222. The transmission gear 224 is fixedly connected to an output shaft of the motor 223 and engaged with the drum gear 2221 of the drum 222.
When the motor 223 is started, the motor 223 drives the transmission gear 224 to rotate, and the drum 222 rotates along with the drum gear 2221 engaged with the motor, so that the front leg retraction belt 21 is accommodated in the housing 221.
The motor 223 is controlled by the switch to start, and the process can be realized in a wired or wireless mode in the prior art, which does not belong to the protection scope of the utility model. The motor can adopt a motor with the model number of 3IK15 RGN.
One end of the drum 222 is fixedly provided with a ratchet 2222.
The fixing groove base 225 is fixed in the case 221. The fixing groove base 225 has a groove opening toward a sidewall of the case 221.
The side wall of the housing 221 has a button 228 disposed in a button 228 disposed hole, the inner end being located within the housing 221 and the outer end being located outside the housing 221.
Pawl 226 is fixedly received on pawl mounting shaft 227. The pawl 226 is matched with the ratchet 2222, the pawl 226 is inserted into the tooth slot of the ratchet 2222, and during the rotation of the drum 222, the pawl 226 slides on the ratchet 2222, which does not affect the rotation of the drum 222, but prevents the drum 222 from rotating reversely, i.e. limits the reverse rotation of the ratchet 2222, thereby avoiding breaking loose the front leg contraction belt 21 due to the excessive canine force.
When pawl 226 is inserted into the teeth slot of ratchet 2222, pawl mounting shaft 227 extends partially into the slot less than the depth of the slot. Pressing button 228 in the direction of housing 221 moves pawl mounting shaft 227 further into the slot, which moves pawl 226 with it until pawl 226 disengages ratchet 2222. At this point, ratchet 2222 may be reversed and the user may pull out front leg retraction strap 21, which is let out to return to its original length outside housing 221, i.e., to release the dog restraint.
The return spring 229 is fitted over a section of the pawl mounting shaft 227 between the pawl 226 and the fixed groove base 225, and has both ends abutting against the pawl 226 and the fixed groove base 225, respectively, specifically, one end abutting against a surface of the pawl 226 facing the fixed groove base 225 and the other end abutting against a peripheral surface of the slot opening of the fixed groove base 225. Pressing the button 228 compresses the return spring 229. Releasing button 228, return spring 229 is reset, urging pawl 226, pawl mounting shaft 227 and button 228 toward the exterior of housing 221 until pawl 226 is reinserted into the tooth slot of ratchet 2222.
Wherein, pawl installation axle 227 and the cross-section phase-match of the slot of fixed slot base 225 avoid pawl installation axle 227 to rock in the slot, and influence pawl 226 to the restriction of rotary drum 222.
The inner end of the button 228 has a stop 2281 circumferentially disposed along its sidewall. When the pawl 226 engages the ratchet 2222, the limiting piece 2281 abuts against the inner sidewall of the housing 221 to prevent the button 228 from moving out of the housing 221 completely.
Wherein, the fixed end 211 of the front leg contraction belt 21 is detachably connected with the side surface of the vest 1 through structures such as buckles, which is convenient for the protective clothing to be put on and taken off.
The upper end of the vest 1 is provided with a hauling rope mounting handle 11.
During the use, dress the protective equipment on the body of dog class, it is specific, can overlap front chest fixed band 3 below dog neck, and two foreleg shrink belts 21 overlap respectively in the root of dog foreleg. When the dogs start bursting, the motor 223 is started, the motor 223 drives the rotary drum 222 to rotate through the transmission gear 224 and the rotary drum gear 2221 at the end part of the rotary drum 222, the front leg contraction belt 21 is retracted into the shell 221, the contracted front leg contraction belt 21 tightly hoops the root part of the front legs of the dogs, and therefore the dogs are prevented from bursting. When the front leg contraction belt 21 needs to be unlocked, the button 228 is pressed, the pawl 226 moves inwards to be disengaged from the ratchet 2222 at the end of the drum 222, and at the moment, the drum 222 can be reversely rotated to pull out the front leg contraction belt 21 wound thereon, so that the restriction on the dogs can be released.
