Description

Dog rope winding device of sauntering

Technical Field

The utility model relates to a dog rope of sauntering especially relates to a dog rope winding device saunters.

Background

At present, more and more people who raise pets need to be pulled by a dog walking rope when the pet is taken out, particularly pet dogs, for safety consideration. The simplest dog leash is of a fixed length, and a dog leash with various telescopic lengths appears on the market later, and the general principle is as follows: the rope is wound on a winding reel, a clockwork spring is arranged on the winding reel, and a locking device for locking the rope is arranged at the same time. When the locking device is opened, the rope can be pulled out at will, and when the locking device is not stressed, the self-tightening function of the clockwork spring can pull the rope back; when the locking device is closed, the length of the rope is fixed.

But current locking device all is the snap-on rope, and locking is relapse to cause the damage to the rope body easily, accelerates the ageing speed of the rope body.

Disclosure of Invention

The utility model provides a dog leash winding device which is not easy to damage the leash body; the problem of have among the prior art to lock easily to the rope body cause the damage repeatedly is solved.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a dog rope winding device saunters, includes shell, bobbin and clockwork spring, and the bobbin rotates with the shell to be connected, and the relative shell of one end of clockwork spring is fixed, and the other end is connected with the bobbin, and the winding has the haulage rope on the bobbin, offers the opening of accessible haulage rope on the shell, its characterized in that: bobbin side be equipped with circular shape backplate, the backplate is coaxial with the bobbin, is equipped with the bayonet socket that a plurality of is the circumference array and distributes on the edge of backplate, sliding fit has the locking piece in the shell, the head of locking piece can with the bayonet socket block, the locking piece receives the shell restraint, only has endwise slip's degree of freedom.

The locking block in the utility model is arranged in a sliding way, when the head of the locking block is clamped with the bayonet on the guard plate, the guard plate is locked, the bobbin can not rotate, and the traction rope on the bobbin can not be pulled; when the locking block is separated from the bayonet, the winding reel can rotate freely. The utility model discloses a rotation of control bobbin is in order to reach the purpose of control haulage rope, and consequently the haulage rope is difficult to impairedly, is favorable to improving the service life of haulage rope.

Preferably, a return spring is connected between the locking block and the shell, and the elastic force provided by the return spring is directed to the guard plate. The rear end of the locking block is connected with a pull ring, the pull ring is positioned outside the shell, the shell is further provided with a holding ring, and the pull ring is positioned in the holding ring. During the use, the hand is held and is held the ring, and the pull ring can be controlled simultaneously to the finger, and outside pulling pull ring just can let locking piece and bayonet socket break away from, and reset spring can let the locking piece kick-back automatically to with the bayonet socket block simultaneously.

Preferably, the housing is provided with an inclined block at the opening in a sliding fit manner, a pressure spring is connected between the housing and the inclined block, the elastic force provided by the pressure spring to the inclined block is in a direction towards the opening, and the opening is also provided with a butting surface parallel to the inclined surface on the inclined block. Part of the thrust applied to the inclined block by the pressure spring is converted into pressure towards the abutting surface, and the traction rope passes through a gap between the abutting surface and the inclined block. The friction that the haulage rope passed through can be increased to pressure between sloping block and the face of coming to and closing, and this friction can offset some pulling force that the clockwork spring rebounded for the haulage rope reduces the shrink rate when automatic withdrawing, avoids contracting too fast.

Preferably, a guide wheel is arranged in the shell and in a region between the opening and the winding drum, and the traction rope passes through the guide wheel and then penetrates out of a gap between the abutting surface and the inclined block.

Preferably, the shell is provided with a lighting device with a replaceable battery, so that night lighting is facilitated.

Preferably, the gripping ring is provided with a gripping block which is made of rubber and the shape of which is attached to fingers.

Preferably, the lighting device is screwed with the shell, and the lighting device is cylindrical.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. the purpose of controlling the traction rope is achieved by controlling the rotation of the winding drum through the sliding locking block, so that the traction rope is not easy to damage, and the service life of the traction rope is prolonged; 2. the thrust of the inclined block is applied through the pressure spring, so that pressure is generated between the inclined block and the abutting surface, the friction force of the traction rope is increased, and the traction rope is prevented from being contracted too fast.
