Abstract

The utility model provides a dust collector with a foldable handle, which comprises a dust collector body and a foldable handle, wherein a locking mechanism is arranged between the body and the foldable handle; a pivoting part is arranged at one end of the foldable handle, which is connected with a rotating shaft; a clamp slot is formed at the pivoting part; the locking mechanism comprises a locking block and a pull arm, which are rotatably connected to the body; the locking block and the pull arm are coaxially and fixedly connected together and axially staggered to each other; and an elastic component is arranged between the locking block and the pull arm. When the locking mechanism is locked, the pull arm is located in a first working position, the locking block is clamped inside the clamp slot, and the foldable handle is fixed relative to the body; and when the locking mechanism is in unlocked, the pull arm is located in a second working position, the locking block is separated from the clamp slot, and the foldable handle rotates relative to the body. The dust collector with the foldable handle is unlocked by pressing the pull arm. Since the design of the pull arm is not limited by the space of the handle, the arm of force of the pull arm is increased by increasing the length of the pull arm, resulting in the reduction of the unlocking force.

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 2, a kind of dust catcher of foldable handle, comprise that a body of dust collector 1 and an end are rotatably connected to folding handle 2 on the described body of dust collector 1 by rotating shaft 37, also are provided with the locking mechanism 3 that makes described folding handle 2 and body 1 relative locking between described body 1 and the folding handle 2.The end that described folding handle 2 is connected with described rotating shaft 37 is articulated section 21, offers draw-in groove 22 on the described articulated section 21; Described locking mechanism 3 comprises the lock dog 33 that is rotatably connected on the described body 1 and dials arm 34, described lock dog 33 with dial that arm 34 is coaxial fixedlys connected and stagger mutually vertically, be provided with elastomeric element 36 between described lock dog 33 and the body 1, this elastomeric element 36 is a torsion spring in the present embodiment, and lock dog 33 pushes against on the external peripheral surface of articulated section 21 by the elastic force of torsion spring.

Described body 1 also comprises the case 11 that is arranged on the described locking mechanism outside, described locking mechanism 3 also comprises the knob 31 that is rotatably connected on the described case 11, with the described knob 31 coaxial cams of fixedlying connected 32, described cam 32 is rotatably connected in the described rotating shaft 37, described group of arm 34 flexibly is against on the outer surface of described cam 32, described knob 31 upper edges circumferentially are distributed with first block 311 and second block 312, have the limited block 12 that is arranged at described knob 31 sidepieces in the described case 11, described limited block 12 is between described first block 311 and second block 312.

Described locking mechanism 3 has lock-out state and released state.Wherein from accompanying drawing 3 as can be seen, when locking mechanism 3 is in the lock state, knob 31 residing positions, knob 31 rotates counterclockwise release, from accompanying drawing 4 and accompanying drawing 5 as can be seen, this moment, limited block 12 blocked first block 311 in the place ahead that knob 31 clockwise rotates, knob 31 can't be clockwise rotated again, this moment, the center of rotation of cam 32 was shorter apart from the distance of dialling arm 34, described group of arm 34 is in first operating position, this moment, described lock dog 33 was stuck in the described draw-in groove 22, described folding handle 2 and body 1 relative fixed, and folding handle 2 is under the deployed condition.

Locking mechanism 3 is under lock-out state, rotating counterclockwise knob 31 makes it arrive the position shown in the accompanying drawing 6, following knob 31 in releasing process cam 32 rotates counterclockwise together, block second block 312 until limited block 12, position as shown in Figure 8, this moment, the center of rotation of cam 32 was longer apart from the distance of dialling arm 34, therefore can push down group arm 34 and rotate arrival second operating position, owing to dial arm 34 and lock dog 33 coaxial fixedlying connected, therefore lock dog 33 rotates thereupon, and break away from draw-in groove 22, and locking mechanism 3 releases, this moment, described folding handle 2 turned with respect to described body 1.

Owing to dial the length of the length of arm 34 greater than lock dog 33, therefore can play the increase arm of force, reduce the effect of active force, make locking mechanism not need the very big power just can release.

By the restoring force of elastomeric element 36, unclamp knob 31 after, dial arm 34 and lock dog 33 and under the effect of elastic force, will automatically reset, dial arm 34 and get back to first operating position, lock dog 33 is got back in the draw-in groove 22, simultaneously, dial arm 34 actuating cams 32, make knob 31 get back to the home position.Torsion spring in the utility model had both been replied for lock dog 33 restoring force was provided, and provided restoring force for knob 31 resets again simultaneously.

The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
