Description

Life buoy traction frame

Technical Field

The utility model relates to a life saving equipment field, concretely relates to life buoy traction frame.

Background

The life buoy is generally arranged in swimming pools, bathing grounds, ships and other places and used for rescuing people falling into water, and under the normal condition, the life buoy can also help a rope so that after the life buoy is thrown out, people falling into water can grasp the life buoy, and the people falling into water can be pulled to the bank or the ships by pulling the rope. But the rope of life buoy, it is easy to tie a knot, and expose easy ageing externally, to this problem, application number 2013201480115's utility model discloses a life buoy support takes "set up rope roller and collapsible crank" key technology, the front of its bottom plate and stand, stand and the bottom and the equal fixed connection of fixed axle of the front central point of rope box, stand and life buoy stores pylon, rope box with the back of stand, the rope shaft passes through the bearing with the rope roller and rotates swing joint, the bottom of rope roller and the equal fixed connection of collapsible crank with the bottom surface of blocking rope board, the lateral surface of rope roller, the fixed axle passes through the bearing with the rope pulley and rotates swing joint. Used for lifesaving. The rope pulley which enables the rope to smoothly enter and exit can facilitate the winding and unwinding and the fixing of the rope.

However, the above solutions have problems: because this kind of life buoy support often sets up in public place, can't avoid someone to be in curious operation crank, for example if the quick antiport crank of people forward rotation crank again, make the rope wind down from the serving roller fast, the rope is piled up in the rope box, be wound on the serving roller fast again, in this process, cause the rope to tie a knot very easily, cause the rope card to die even between the lateral surface that keeps off the rope board and the internal face of rope box, and the rope is built-in the rope box, can't know its internal fault through visual observation, if take place emergency and need use, if discover unable use, then cause the incident very easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a life buoy traction frame that security is better.

The utility model provides a technical scheme that above-mentioned problem adopted is:

a life buoy traction frame is characterized in that: including the support, be used for convoluteing the coiling piece, the crank and the one-way drive mechanism of stay cord, wherein, coiling piece rotates and installs on the support, and the coiling piece is connected to the crank through one-way drive mechanism, is fixed with the box body on the support, and the stay cord window that is used for pulling out the stay cord is offered to the box body, the coiling piece is located the box body.

The utility model discloses the life buoy traction frame adopts the connected mode that the coiling piece is connected to the crank through one-way drive mechanism for when the crank is rotated in the reverse direction, can't drive the coiling piece and rotate, and the stay cord is pulled out the back, when needing to pack up the stay cord, when the crank is rotated in the forward direction, can drive the coiling piece and rotate, therefore the security performance of life buoy traction frame is higher, can't make the rope to wind out through the crank, can avoid the problem that the rope that the people leads to is knoed for positive and negative rocking crank.

Further, as preferred, the winder includes the winding reel and fixes the baffle at the winding reel both ends, and the baffle is circularly, and the both sides wall of box body also is circularly, and the clearance between the baffle and the box body lateral wall that corresponds the side is less than 8mm, and the diameter of baffle is greater than 90% and is less than 100% box body lateral wall diameter, and increase baffle external diameter just reduces the clearance and can avoid the stay cord card to go into between the lateral surface that keeps off the rope board and the internal face of rope box.

Further, as preferred, seted up the access hole on the box body, rotate on the box body and install the access cover that is used for covering the access hole. The access cover is convenient to open for internal maintenance.

Further, as preferred, the access cover is fixed with a lock, thereby facilitating locking of the access cover.

Further, preferably, a swinging member is attached to an edge of the window, and the swinging member has a through hole for pulling out the pull cord. By adopting the structure, the swing amplitude of the pull rope is limited in the pull rope rolling-in process, so that the rope is prevented from being clamped between the outer side surface of the rope baffle plate and the inner wall surface of the rope box.

Preferably, the swinging member is in an inverted U shape, the upper end of the swinging member is rotatably mounted on the edge of the window, and the lower end of the swinging member is rotatably mounted with the roller.

Further, as preferred, the lower extreme of box body has seted up the mouth that leaks, is fixed with the grid plate that is used for covering the mouth that leaks on the box body. By adopting the structure, the water discharging box body of the pull rope is convenient.

Further, preferably, the one-way transmission mechanism is a ratchet mechanism.

Preferably, the handle is rotatably mounted to the crank.

Compared with the prior art, the utility model, have following advantage and effect: the safety performance of life buoy traction frame is higher, can't make the rope wind out through the crank, can avoid the problem that the rope that leads to is knoed for the positive and negative rocking crank of people.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Referring to fig. 1-4, the life buoy traction frame of the embodiment comprises a support 1, a winding member for winding a pull rope, a crank 3 and a one-way transmission mechanism, wherein the winding member is rotatably mounted on the support 1, the winding member is connected to the crank 3 through the one-way transmission mechanism, a box body 4 is fixed on the support 1, a pull rope window 41 for pulling out the pull rope is formed in the box body 4, and the winding member is located in the box body 4. The winder includes the winding reel 21 and fixes the baffle 22 at winding reel 21 both ends, baffle 22 is circularly, and the both sides wall of box body 4 also is circularly, and the clearance between baffle 22 and the 4 lateral walls of box body that correspond the side is less than 8mm, and the diameter of baffle 22 is greater than 90% and is less than 100% 4 lateral walls of box body diameter, and increase baffle 22 external diameter just reduces the clearance and can avoid the stay cord card to go into between the lateral surface of keeping off the rope board and the internal face of rope box.
