Description

The belt pincers

Technical field

The present invention relates to a kind of belt pincers, relate in particular to a kind of belt pincers, it has member that is used to receive the recess that is wound on rod jaw pin belt on every side and the fastener that is used for first member is clamped to second member.

Background technology

Usually, forklift comprises and pitches the door frame that is connected with the lifting weight.Lift system generally includes chain.Chain can be fixed on the door frame through U-shaped clamp.Further, chain needs periodical maintenance, comprises cleaning and lubricated.

It is well-known in promoting application, utilizing belt, for example in the elevator.The end that the belt pincers are used for fixing belt is known to pulley or on the anchor.The belt pincers comprise the plate that extends through belt and extend through plate and the bolt of belt.

Representational patent is a U.S. Pat 4185791 (1980); It discloses a kind of equipment of avoiding belt from tractor, to be pulled out; It comprises belt pincers fixer and base component, and it has closely isolated surface, and it limits a gap; Belt passes this gap, and belt leaves base component forward at angle from this gap.Fixer receives the belt pincers with grasping surface, and grasping surface is outstanding slightly from the fixer surface, and partly limits this gap.Fixer pivots on base component, and belt pincers and fixer to keep on belt clamps not with belt engages the direction around pivot axis be spring-loaded.Make traction belts is passed gap making every effort to promote suddenly and fixer is pivoted backward or wave forward suddenly, thereby with the grasping surface and the belt joint of belt pincers.Forward direction tilts, and the horizontal wedge-shaped surface on belt pincers and belt pincers fixer clamps belt and clamps tightly against to belt, and it is moving to prevent that it is drawn forward.

It is former to be not known, promptly easily improve belt and the chain that directly is used for the forklift door frame is used or similar application in.

People are needed to be a kind of belt pincers, and it has the member that comprises the recess that is used to hold the belt of being reeled around rod jaw pin, and the fastener of clamping first member and second member.The present invention satisfies these demands.

Summary of the invention

Main aspect of the present invention is a kind of belt pincers, and it has the member that comprises the recess that is used to hold the belt of being reeled around rod jaw pin and is used for first member is clipped to the fastener on second member.

Others of the present invention will be pointed out through following description of the present invention and accompanying drawing or made obvious.

The present invention includes the belt pincers; It has first member, passes through second member that hinge combines with first member; Second member has the recess that is used to hold belt; Belt can be reeled around rod jaw pin, be used for first member is clipped to the fastener on second member, and first member has rod jaw pin is remained on the side sections in the recess.

Description of drawings

Combined and formed for example clear the preferred embodiments of the present invention of accompanying drawing of a specification sheets part, and be used to explain principle of the present invention with the specification sheets book.

Fig. 1 is the lateral plan of belt pincers.

Fig. 2 is the bottom perspective view of belt pincers.

Fig. 3 is the front elevation that on door frame, has the belt pincers of belt.

Fig. 4 is the lateral plan of the belt pincers on the belt.

The specific embodiment

Fig. 1 is the lateral plan of belt pincers, and belt pincers 100 comprise and first member 10 of 20 one-tenth hinged relationship of second member that hinge 30 is disposed in the end of member 20.

Recess 21 holds rod jaw pin C.Rod jaw pin C is used to be bonded on the ring of the end of flat belt, sees Fig. 3.The present invention has replaced the chain of common use in forklift is used, and makes the belt (see figure 3) can be used to replace chain and needn't be to the existing door frame mechanism (not shown) that changes.Further, be via threaded fasteners 50 conjugate foramens 24 because the unique carrying of belt connects, the improvement of belt can be accomplished under professional tool or the situation to other modification of door frame not having.

Recess 21 is shaped as to hold and is wound on rod jaw pin C belt on every side.Recess 21 has enough degree of depth so that the axis A of rod jaw pin C is arranged to inwardly 23 1 space D 1 in distance surface.This has optimized the load-carrying properties of belt pincers and has minimized the load tendency opened of belt pincers by the strong hand simultaneously.The requirement that this stretching that has reduced fastener 40 is conversely again carried.Rod jaw pin C is not fixedly attached to the belt pincers, but after belt was wound onto around the rod jaw pin C, rod jaw pin C was inserted in the recess 21.

Fig. 1 is the belt pincers at open position.When the member of closing 10 has covered member 20, step up power thereby belt is applied one, so the belt pincers considered to be in the full load of belt.

Fig. 2 is the bottom perspective view of belt pincers.Member 10 comprises side sections 11 and 12.Each side sections 11 and 12 extends out from middle body 14.The cross-sectional plane of member 10 has " C " shape.Member 20 is inserted between side sections 11 and 12 when closing at the belt pincers.Through operation hinge 30, each side sections 11,12 can closely be aimed at second member 20.

The hole 13 that is positioned at middle body 14 will receive the for example fastener of bolt 40, referring to Fig. 3.Bolt 40 makes that the belt pincers are clamped around belt B and rod jaw pin C.Further, exert pressure to belt through member 10 is pushed in surface 25, with the gripping power of enhancement apparatus.

Member 20 comprises the hole 22 that holds from the hole 13 fasteners 40 that extend out, referring to Fig. 3.Fastener passes belt and member 10 and member 20 is clipped together, and has guaranteed that therefore belt is inner at the belt pincers.

On the machine that belt clipper joint to for example forklift is such, threaded fasteners is used to engagement with threaded aperture 24.

Selectively, fastener need not extend through hole 13,22, but can comprise the shelf of one " C " shape, and this shelf is bonded on each member 10,20.The belt pincers of " C " shape are known in the art.Belt pincers among the present invention allow fastener 40 to be used to cut out the belt pincers, and avoid in belt, forming the necessity (like this can reduce the stretching load-carrying properties of belt) in the hole that holds fastener simultaneously.

Fastener 40 possibly comprise the combination of any known screw bolt and nut 41.Alternatively, hole 22 can be shaped on screw thread and be cancelled the needs to nut.

In another embodiment, first member 10 is soldered to second member 20 during in off position in the belt clamper.In order to take off belt, weld seam can be ground off.

Fig. 3 is the front elevation that on door frame, has the belt pincers of belt.The threaded fasteners (not shown) is fixed to attachment face (MS) with the belt pincers.Hinge 30 is not the stretched carrying that must help to bear belt, though hinge 30 has been taken on the fulcrum that member 20 is pushed to member 10.But the major part tension load of belt is transferred to rod jaw pin C from belt, passes to member 20 then and passes to fastener 50 again, referring to Fig. 5.Member 10 provides gripping power to make rod jaw pin C remain in the recess 21.

Fig. 4 is the lateral plans of belt pincers on belt.Show two belt pincers 100 and be connected belt B therebetween.Design of the present invention allows in a given application, to use whole rated load, nominal loads of belt.

Although a kind of form of the present invention is recorded and narrated in this, it will be conspicuous to those skilled in the art, and the modification on structure and part relation can be made, and does not deviate from essence of the present invention described here and scope.
