Abstract

The utility model discloses a tubular-rod high speed link device, including a body and connecting rod of the body. The link device is characterized in that the device body links to a S shape lock piece. One end of the lock piece is a hook-type lock tip which is embedded in the hole on the rod wall. The another end is the hook-type lock hook in which the lock piece cover is inserted; the link axel is a screw rod which goes sequentially through the crosswise adjusting slot on the lock piece cover, the through hole of the device body and the axel hole of the lock piece. Then they are screwed with the nut so that the lock piece cover, the device body and the lock piece are locked and connected. The device also sets a press-spring, one end of it holds out against the below of the lock piece cover and the another one against the above of the link axel outer with the lock tip of the lock piece to press the lock tip into the hole on the rod wall. The utility model has advantages of simple structure, light weight, easy assembly and disassembly and has a function of double fall-off-proof.

Description

The Quick Connect Kit of tubular rod

Technical field:

The utility model relates to a kind of Quick Connect Kit of tubulose tubular rod, particularly relates to the Quick Connect Kit of the garden instrument of band bar.

Background technique:

In the prior art, various instrument with rod unit, especially garden instruments, as hedge clipper, branches of tall trees shovel etc., what need bar and bar is connected to detachable form conveniently to carry or to change fast working head.For guaranteeing to use reliably, the connection of most of similar tool adopts screw to add lock pin, this Placement is given the dismounting before copying mechanically or is changed working head fast and brings some inconvenience, in the course of the work, these protrude positions often and scratchings such as branch, rattan, very easily cause screw and lock pin to get loose, will certainly cause working head come off worker of hurting or people on every side.

Summary of the invention:

The utility model provides a kind of Quick Connect Kit of tubular rod, and its purpose is to overcome the prior art shortcoming, and a kind of connection set that connects the dismounting rapid and convenient and have dual Drop-proof function is provided.

For reaching in above-mentioned purpose, the utility model adopts following technological scheme:

The Quick Connect Kit of tubular rod comprises body and the bar that is connected with body, it is characterized in that: have the serpentine locking plate and be articulated on the body, locking plate one end is hook-shaped lock point, the lock point embeds in the hole set on the bar wall, and the locking plate the other end is hook-shaped latch hook, has the locking plate lid and inserts in the hook-shaped latch hook; The hinging shaft of locking plate is a screw rod, and screw rod screws togather with nut and locking plate lid, body, locking plate three are locked and be connected after passing the axis hole, the through hole on the body of lateral adjustments groove that locking plate covers, the through hole on the body, locking plate successively.

Said structure is after locking plate lid inserts latch hook and is locked on the body by bolt and nut, and locking plate just can't rotate around hinging shaft, and the lock of the other end is deviate from sharp just can't be from bar the set hole, and bar and body are linked together.Only need unclamp screw rod, the locking plate lid can skid off latch hook along the lateral adjustments groove, pushes latch hook, and locking plate can rotate around hinging shaft, and lock is deviate from the sharp hole set from bar, and bar can easily be taken out.

Have stage clip, stage clip one end contact below locking plate lid, the other end contact outside the hinging shaft of locking plate, have the lock point part above and will lock set hole on the sharp ramming stem wall.

Above-mentioned stage clip effect is, even it is loosening to work as the screw rod accident, the locking plate lid skids off the latch hook of locking plate, and stage clip also can be pushed down the lock point of locking plate, if do not give the latch hook boost pressure, locking plate also can't rotate around hinging shaft, and bar can not deviate from from mechanism yet.Thereby play safety effect.

The lock point is the barb that tilts to the hinging shaft direction.

In the dress bar, the stage clip compacting locking plate drag that assembling produces to bar can easily be overcome by the component that the outer inclined-plane of the barb of the lock point of locking plate produces.Thereby make assembling easier.

Nut is built in the inward recess set on the body fully.

Nut be provided with inward recess in after, can reduce being exposed to the outside and may being avoided getting loose by the position of swiping.

Described screw jacket was provided with cover.

The above-mentioned cover of crossing shields to screw rod, makes hinging shaft be more conducive to locking plate and rotates.

Usefulness of the present utility model is: the body by device, the organic combination of crossing cover, locking plate, locking plate lid, stage clip etc. have been guaranteed device to the convenience of the dismounting of bar and fast, thus compact structure, in light weight, connect convenient disassembly and have dual Drop-proof function etc.

Description of drawings:

Fig. 1 is the structural representation of locking state of the present utility model

Fig. 2 is the A-A sectional drawing of Fig. 1

Fig. 3 is that the utility model unclamps the disassembly status schematic representation.

Embodiment:

Below in conjunction with drawings and Examples the utility model is described in further detail:

As Fig. 1, the utility model most preferred embodiment shown in Figure 2, the utility model comprises body 8 and the bar 4 that is connected with body 8, having serpentine locking plate 1 is articulated on the body 8, the hinging shaft of locking plate 1 is that a screw rod 5 and screw rod 5 outer sheathed mistakes overlap 6, the lateral adjustments groove that screw rod 5 (and cross and overlap 6) passes on the locking plate lid 2 successively is (not shown in the figures, it is horizontal rectangular groove, width covers 2 less than screw rod 5 head diameters for screw rod 5 locking locking plates, after unclamping screw rod 5, can cover 2 position) for regulating slide lock tabs, through hole 81 on the body 8, the axis hole 10 of locking plate 1, through hole 82 back on the body 8 be contained in fully that nut 7 in the shrinkage pool set on the body 8 83 screws togather closely and with locking plate lid 2, body 8, locking plate 1 three locks connection.

Locking plate 1 one ends are hook-shaped latch hook 11, and locking plate lid 2 inserts in the hook-shaped latch hook 11; Locking plate 1 the other end is barb-like lock point 12, and lock point 12 embeds in the hole 40 set on bar 4 walls; Have stage clip 3, stage clip 3 one end contacts below locking plate lid 2, the other end contact outside the hinging shaft of locking plate 1, have lock point 12 part above and will lock set hole 40 on sharp 12 ramming stems, 4 walls.

As Fig. 3, during removal rod 4, only need unclamp screwing togather of screw rod 5 and nut 7, slide lock tabs lid 2, depress latch hook 11 1 ends of locking plate 1 with thumb, then locking plate 1 is promptly crossed around hinging shaft and is overlapped 6 and rotate, and the lock of locking plate 1 point 12 can be deviate from from bar 4 like this, just can take down bar 4 easily, realization bar 4 separates with body 8.
