Description

Bundling device

The present invention relates to a binding aid, and more particularly to a binding device that can easily reelate a strap.

The Patent No. I325396 of the Republic of China is disclosed in the patent application No. I325396. The utility model relates to a pulling device for winding a strap. The puller mainly comprises a body, a pulling member and a rotating device. The body has a first end and a second end, the first end of which is provided with a fixing rope, and the second end thereof is provided with a pivot. A bundle of straps is attached to the pivot shaft, and a ratchet wheel rotatable simultaneously with the pivot shaft is further disposed at both ends thereof. The body is provided with an elastically slidable fastener, and the fastener is elastically resistable against the ratchet. A pivot hole is defined in the second end of the body, and a pivoting portion is formed on the periphery of the pivot hole. The trigger member has a first end and a second end, the first end of which can be pulled by a user, and the second end of which has a pivot hole. The pivot hole of the trigger member is pivotally disposed on the pivoting portion of the body and is pivotable relative to the body. An elastically slidable positioning member is disposed in the triggering member, and the positioning member is elastically resistable against the ratchet. The pivot shaft penetrates the pivot hole of the body and the pivot hole of the trigger member. Thereby, the pulling member is operated to move the positioning member and the fastener away from the ratchet, so that the pivot shaft can be easily rotated to reel the strap.

Since the second end of the body is when the pivot hole is opened, that is, And forming the pivoting portion protruding outward along the axial direction of the pivot hole, so that the thickness and length of the supporting structure formed by the pivoting portion are limited, so that the pivoting portion resists the pulling member relative to the body When the buckling belt is pivoted, the tension of the strap is limited along the radial direction and is easily deformed. However, the deformation of the pivoting portion directly causes the shape of the pivot hole to be deformed, thereby affecting the pivoting. Smoothness, if severe, will completely prevent the trigger member from pivoting relative to the body.

Accordingly, it is an object of the present invention to provide a binding device having a high pivoting structural strength.

Thus, the binding device of the present invention comprises a body, a trigger member, and a plurality of bearing members.

The body includes a fixed end and a pivot end disposed oppositely. The fixed end is provided with a fixing rope. The pivoting end has a first panel that is spaced apart and pivoted for a pivot. The first plates each have a pivot hole for the pivot. The pivot is connected with a strap, and the opposite ends of the pivot are respectively sleeved with a ratchet that can rotate with the pivot. The body is provided with a resiliently sliding fastener. The card fastener is resiliently resistable against the ratchets.

The trigger member includes a pivoting end and an operating end disposed oppositely. The pivoting end has two second plates that are spaced apart and pivoted to the pivots and respectively adjacent to the first plates. The second plates each have a pivot hole for the pivot. The operating end is for the user to pull. A locating member that is elastically slidable is disposed in the trigger member. The positioning member is elastically resistable from the ratchet.

The bearing members are sleeved on the pivot and are respectively disposed through the pivot holes of the adjacent first and second plates. Each bearing member includes a set of bearing portions disposed on the pivot shaft and an abutting flange extending axially outward from the outer peripheral surface of the bearing portion.

The pivoting end of the body and the pivoting end of the trigger member are pivotally disposed on the pivot shaft by the bearing members, whereby the trigger member is pivotable relative to the body.

The lever is operated to prevent the positioning member and the fastener from coming against the ratchet, and the pivot is freely rotatable to reel the strap.

Preferably, the ratchets are located outside the first plate members, and the second plate members are respectively sandwiched between the adjacent first plate members and the ratchets, and the abutting flanges of the bearing members are respectively placed Between the adjacent second plate and the ratchet.

Preferably, the ratchets are located outside the first plate members, and the second plate members are respectively sandwiched between the adjacent first plate members and the ratchets, and the abutting flanges of the bearing members are respectively placed Between adjacent first and second plates.

Preferably, the pivot shaft is composed of two parallel shaft members arranged at two parallel intervals and two latch members respectively disposed at opposite ends of the long shaft members; each of the ratchet wheels has two separate shaft members for respectively. a first through hole, and a first spacing portion formed between the first through holes; the bearing portion of each bearing member has two second through holes respectively for the long shaft members to pass through, and a second spacer formed between the second through holes.

Preferably, the first plates each have an ejector portion that can contact the fastener.

Preferably, the second plates further have a sliding portion for the positioning member to abut against the sliding portion, and a restricting portion of the positioning member at a side of the sliding portion.

The effect of the present invention is that since the bearing members are independently fabricated components, the bearing portions can be formed into a thicker and longer structure to resist the pivoting of the trigger member relative to the body. When the belt is brought, the tension along the radial direction is generated, thereby avoiding deformation of the bearing portions, directly deforming the shape of the second through hole, thereby affecting the smoothness of the pivoting.

The fastening portions 131 respectively protrude from opposite sides of the body 1 . The fastening portions 13 are respectively engageable between the ratchet teeth 51 of the ratchets 5, so that the fasteners 13 are elastically resisted. The effect of the ratchets 5.

The triggering member 2 includes a pivoting end 21 and an operating end 22 disposed oppositely. The pivoting end 21 has two second plates 211 spaced apart from each other and pivoted to the pivot 4 . The second plates 211 are respectively sandwiched between the adjacent first plates 121 and the ratchets 5 . The second plate members 211 respectively have a pivot hole 210 through which the pivot shaft 4 is disposed, and a pushing portion 212 of the fastening portion 131 of the fastener 13 of the body 1 . The operating end 22 is provided with a grip bar 221 for the user to hold. A locating member 23 that is elastically slidable is disposed in the triggering member 2. A positioning portion 231 is formed on each side of the positioning member 23 . The positioning portions 231 respectively protrude from both sides of the trigger member 2. The positioning portions 231 are respectively abutting against the sliding portions 122 of the first plate members 121, and are respectively inserted between the ratchet teeth 51 of the ratchets 5, so that the positioning members 23 are elastically resisted. The effect of the ratchets 5. The positioning member 23 is opposite to one end of the positioning portions 231 and is provided with a pull rod 232 for the user to pull.

The bearing members 3 are sleeved on the pivots 4 and are respectively disposed through the pivot holes 120 and 210 of the adjacent first and second plates 121 and 211. Each of the bearing members 3 includes a bearing portion 31 provided on the pivot shaft 4 and an abutting flange 32 extending axially outward from the outer peripheral surface of the bearing portion 31 perpendicularly to the pivot shaft 4. Each bearing portion 31 has a second through hole 310 through which the pivot shaft 4 is bored. In the preferred embodiment, the abutting flanges 32 of the bearing members 3 respectively abut against the outer sides of the second plate members 211 and are sandwiched between the adjacent second plate members 211 and the ratchets 5 However, the direction in which the bearing members 3 are disposed may be changed as the ratchets 5 are disposed, such that the ratchets 5 are disposed on the first plates 121. On the inner side, the abutting flanges 32 of the bearing members 3 respectively abut against the inner side surfaces of the first plate members 121 and are sandwiched between the adjacent first plate members 121 and the ratchets 5.
