Abstract
The purpose of this utility model is to provide a kind of electric hammer dust-proof radiating disk, can reduce harm of the dust to electric hammer, extend the service life of electric hammer.In order to realize the purpose, a kind of the utility model electric hammer dust-proof radiating disk, on the motor shaft held between brush assemblies and bearing in electric hammer, including circular disk body, bearing housing holes are provided among the circular disk body, a plurality of heat sink strip on circular disk body radial direction is evenly distributed with the circular disk body.By such setting, a kind of electric hammer of the utility model avoids dust from entering in the motor at electric hammer rear portion causing damage with dust-proof radiating disk by itself barrier effect.Certain thermolysis is played in the middle part of electric hammer simultaneously, extends the overall service life of electric hammer.
Description
Technical field
It the utility model is related to a kind of electric tool component, more particularly to a kind of electric hammer dust-proof radiating disk.
Background technology
Electric hammer is a kind of common tool, and one mentions electric hammer, the scene that dust powder is flown upward when everybody can be envisioned as work.
It can all consider dust-proof problem when therefore designing electric hammer in the prior art.Such as Patent No. 201420209115.7 in the prior art
Utility model《Dustproof electric hammer》In disclose a kind of dustproof electric hammer, its drip irrigation device is that drill bit overcoat is set up defences dust hood,
Electric hammer body is circumferentially distributed projection for cylinder and outer surface with respect to drill bit side provided with some, and dust cover is cylindrical and it
One end is provided with accommodating cavity, and the other end is provided with the through hole that power supply hammer passes, and accommodating cavity includes roof and is set around the interior of roof surrounding
Side wall, some blocks being interval with madial wall, distance of the block towards the side end face of roof one to roof is equal to the thickness of projection,
The gap length and shape formed between block is adapted with projection, and both ends are made of clear material, and connecting portion is by transparent
Elastomeric material is made, and when needing to use electric hammer, dust cover can be covered outside drill bit, can play good dust-proof work
With, avoid at work dust fly upward, when electric hammer need not be used, dust cover can be dismantled, not influence the entirety of electric hammer
It is attractive in appearance, and the installation and removal simple and fast of dust cover is convenient.
But the electric hammer dust cover in documents can only reduce harm of the dust flown upward to operating personnel, can not really solve
Certainly dust invades the problem of influence electric hammer service life in casing in the course of the work.
Utility model content
The purpose of this utility model is to provide a kind of electric hammer dust-proof radiating disk, can reduce harm of the dust to electric hammer,
Extend the service life of electric hammer.
In order to realize the purpose, a kind of the utility model electric hammer dust-proof radiating disk, brush group is held in electric hammer
On motor shaft between part and bearing, including circular disk body, bearing housing holes, the circular disk body are provided among the circular disk body
On be evenly distributed with a plurality of heat sink strip on the circular disk body radial direction.
Preferably, the circular disk body is provided with the first crowning towards the bearing housing holes edge for holding brush assemblies direction, and first
The section of crowning is trapezoidal.Because dust holds what brush assemblies direction side came from direction when electric hammer works, therefore herein
The section of first crowning is trapezoidal, i.e., front end is small, and rear end is big, can effectively reduce the possibility that dust is entered in bearing housing holes.
Preferably, the circular disk body is provided with the second crowning towards the bearing housing holes edge in bearing direction, and described second
The height of crowning is higher than the height of heat sink strip.The effect of second crowning is to ensure that heat sink strip in the course of the work and bearing
The distance between, avoid both from rubbing.
Preferably, the heat sink strip is T-shaped structure, and the top of T-shaped is close to the home position of circular disk body.It is such
Structure can be effectively increased the area of radiating, improve the effect of radiating.The top of T-shaped close to the home position of circular disk body be for
Make it that whole heat dissipation plate is more stable.
Preferably, the quantity of the heat sink strip is 6-8 bars.Very few heat sink strip radiating effect is bad, can then cause too much
Cost is too high.
By such setting, a kind of electric hammer of the utility model avoids dust with dust-proof radiating disk by itself barrier effect
Enter in the motor at electric hammer rear portion and cause damage.Certain thermolysis is played in the middle part of electric hammer simultaneously, it is whole to extend electric hammer
The service life of body.
Brief description of the drawings
Fig. 1 is a kind of positive structure schematic of electric hammer dust-proof radiating disk of the utility model.
Fig. 2 is a kind of side structure schematic diagram of electric hammer dust-proof radiating disk of the utility model.
Embodiment
As shown in Figure 1 and Figure 2：1. a kind of electric hammer dust-proof radiating disk, holding between brush assemblies and bearing in electric hammer
Motor shaft on, it is characterised in that：Including circular disk body 1, bearing housing holes 2, the circular discs are provided among the circular disk body 1
The a plurality of heat sink strip 3 on the radial direction of circular disk body 1 is evenly distributed with body 1.The circular disk body 1 is towards holding brush assemblies
The edge of bearing housing holes 2 in direction is provided with the first crowning 4, and the section of the first crowning 4 is trapezoidal.The direction of circular disk body 1
The edge of bearing housing holes 2 in bearing direction is provided with the second crowning 5, and the height of second crowning 5 is higher than the height of heat sink strip 3
Degree.The heat sink strip 3 is T-shaped structure, and the top of T-shaped is close to the home position of circular disk body 1.The number of the heat sink strip 3
Measure as 6-8 bars.
In summary, the utility model occupation mode or with prior art as, but improve overall scattered of electric hammer
Hot property and anti-dust performance, so as to improve the service life of electric hammer.
