Description

Percussive type hand hammer

The utility model relates to a kind of nailing device, is particularly suitable for utilizing the fixing and binding object of " ∏ " type machine nail.

Portable nailing device in the past has stapler commonly used and steam-operating ailing machine respectively.Though the former is simple in structure,, generally only be applicable to the bookbinding of thin, softer object such as paper, plastics because power is too little; Though latter's power is big, there is complex structure, costs an arm and a leg, especially can not break away from the shortcoming that source of the gas uses, had a strong impact on its mobility.

It is big that the purpose of this utility model provides a kind of power, do not need the nailed apparatus of other energy, and in brief: the utility model is a kind of under the manpower effect, the boosting function of bar is shouldered in utilization, make spring energy-storage, and, realize the device of nailing by the ballistic motion that burst mechanism produces drift.

The utility model is achieved in that it impacts part by body part, reinforcement part, burst and form for the nail part.After the handle of reinforcement part was stressed, through leverage, power was exaggerated, and passes to push rod jack-up block stamp by fork again, makes the main spring that is located on the block stamp be compressed energy storage; Drift rises above behind the machine staple height, for spike devices the machine nail is fed working chamber; Thruster face on the push rod contacts with stop, and limited device is pushed sidesway open in continuing the process that rises, and causes push rod and block stamp to disengage, and block stamp drives drift shock machine nail under the effect of main spring, makes the machine nail squeeze into other object.

Casing partly mainly is connection and supports each part that by casing, anvil block and cushion pad are formed.Casing includes block stamp chute, handgrip and nail road, is made into combined type usually.Except that handle other mainly moves other part and generally all is installed in casing inside, on the bigger nailed apparatus of power handgrip is not set generally.

Reinforcement is passed to push rod after partly utilizing lever and toggle link principle that people's active force is increased.Generally be made up of handle and fork, wherein handle is normally withheld the general name of bar and connecting rod assembly.Bar is withheld in the general employing of the nailed apparatus that power is bigger and fork is fixedly connected, the mode that push rod is hinged with fork again.Lower-powered nailed apparatus is generally passed to the fork postbrachium by pin with power, promotes the push rod ejection block stamp that links on its forearm by fork again.Complicated nailed apparatus, its boosting system can be assembled according to instructions for use, can increase and decrease or change replacement part on demand during assembling, and four kinds of forms commonly used are:

1. withhold bar and fixedly connected with fork, push rod and fork forearm are hinged to the lever force-increasing mechanism.

2. withhold bar and fixedly connected with fork, push rod and fork postbrachium are hinged to the toggle rod type force-increasing mechanism.This mechanism can be in couples symmetry use the balance when keeping this device work.

3. withhold bar and casing is hinged, connecting rod and fork postbrachium are hinged to the pressure lever type force-increasing mechanism.

4. withhold bar and be connected with the fork postbrachium, connecting rod and casing are hinged to button bar formula force-increasing mechanism.

Easy special-purpose nailed apparatus is owing to only adopt the fixing force-increasing mechanism of a cover, so when the preceding two kinds of force-increasing mechanisms of employing, generally will withhold bar and rocking bar is made one.

It is the mechanism that causes the block stamp ballistic motion that part is impacted in burst, also is most important mechanism in this device.Mainly contain compositions such as push rod, stop, block stamp, main spring, reduction torsion spring, holddown spring and drift.Fork is hinged by shop bolt, reduction torsion spring and casing, push rod and fork are hinged by movable pin and holddown spring, individual stop is arranged above the push rod activity, and the general using bearing pin is made stop, and its place ahead is a block stamp, the compacted spring compression of push rod is on block stamp, fulcrum for the push rod ejection is arranged on the block stamp, and this fulcrum can be the step of projection or the hole, cave of depression, and main spring is installed on the block stamp, drift can be installed in bottom the block stamp or all around, can be integrated with block stamp.

For the nail part is the mechanism of the timely feeding of machine nail working chamber.Form by multiple-grooved sprig road with for the nailing machine structure, multiple-grooved sprig road is to adopt frid that the nail groove of casing bottom is separated into multiple groove, utilize the moon nail road and the sun nail road of the interior lateral surface composition different size of frid, the effect that has branch to follow closely simultaneously is to adapt to the requirement of different size machine nail.Complicated nailed apparatus aspiration-type commonly used is united for nail for nail device and propelling movement type nails introducer, the former adopts magnet steel to inhale the principle of iron, by attracting that the machine nail is introduced working chamber, has the effect of steady nail and location, can use common single pin type machine nail, but only be applicable to the machine nail that magnetic material is made; The latter adopts spring and nail pushing device that the machine nail is pushed working chamber, and performance is more stable, and is applicable to the machine nail of various materials and specification.Working chamber is the drift space that the back occurs of rising, be to hold the position of being followed closely by shock machine, its width and nail groove with, length is followed closely wide 0.01～0.7mm than machine.

Easy special-purpose nailed apparatus can only establish one fixing for nailing machine structure and single road of following closely of only using for a kind of machine nail.

The utility model was compared with former various portable nailed apparatus, owing to adopted force-increasing mechanism and burst beater mechanism, so steering force is less, but impact strength is very big; Owing to adopted multiple-grooved sprig road, can adapt to " ∏ " type machine nail of multiple width specifications and single pin machine nail of stripe shape and use simultaneously.Because the very light in weight of nailed apparatus does not need other power again, can in all case use in addition, thus have easy to operate and maneuverability advantage, can be widely used in industries such as power supply, furniture, building, traffic, shoemaking.After having increased the mechanism that makes " ∏ " type machine nail change pin, can also be used for industries such as office, daily, packing and publication, be a kind of popular tools that can popularize use.

Description of drawings and embodiment:

Accompanying drawing is mechanism's working state schematic representation comparatively complicated among the utility model embodiment, because this embodiment can make up force-increasing mechanism and supply the nailing machine structure by instructions for use, so the course of action of its force-increasing mechanism is different, but action such as the burst impact of its major part is constant.
