Detailed description of the invention
Embodiment one
The hand-held impact spanner of the present embodiment as shown in Figure 1, Figure 2 and Figure 3, comprises the housing (meaning not shown in the figures) settling drive motors, and the handle 1 of two involutory handle shell 1-A, 1-B formations is extended in the bottom of housing.There are bottom handle 1 two involutory connection shell 3-A, 3-B of plug-in mounting power brick 2.Two involutory handle shell 1-A, 1-B are built with Connection Block 4.Involutory two connect shell 3-A, 4-B built with circuit board 5.
Connection Block 4, as shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, combines by adopting upper pedestal, the lower base of encapsulate technique.Upper pedestal is the metal rigidity component 4-A that both sides, bottom have manhole respectively, and lower base is the rubber-elastic members 4-B of embedding two manhole.Be middle part cylinder 4-7 between the manhole of both sides, rigid member 4-A bottom, middle part cylinder 4-7 has vertical perforations 4-5, for connecting the wire of circuit board 5.Elastic component 4-B forms orifice flanging 4-6 at rigid member 4-A manhole two ends, can be formed like this rigid member 4-A clad structure, not only mutually can locate, also more be conducive to vibration isolation.Be connected as a single entity by the horizontal bar 4-8 on cylinder 4-7 surface, coated middle part between the manhole orifice flanging 4-6 of both sides, rigid member 4-A bottom.The upper and lower both sides of horizontal bar 4-8 of elastic component 4-B both sides extend horizontally away upper and lower elastic fin 4-9 respectively, thus make the elastic-member portions of embedding two manhole 4-4 and elastic fin 4-9 become combination jointly to play each entirety to (comprising vertical and horizontal) vibration isolation effect.The corresponding elastic fin 4-9 place of rigid member 4-A extends by middle part cylinder 4-7 the fin embedding elastic fin 4-9 and serves as a contrast muscle 4-10, by the liner effect of rigid member, the elastic deformation of elastic component can be constrained in suitable scope like this.Involutory two connect shell 3-A, 4-B has the vibration isolation sheet 3-1 inserted between corresponding upper and lower elastic fin 4-9 respectively.
Rigid member 4-A and elastic component 4-B has a pair level perforation 4-3,4-4 respectively.The horizontal bearing pin 1-3 a pair with internal thread hole being each passed through rigid member 4-A a pair level perforation 4-3 is extended in the interior bottom of one of two involutory handle shells 1-B, after involutory with two involutory another 1-A of handle shell, be connected by the two trip bolt 1-2 penetrated from outside.Involutory two connect one of shell 3-B internally extends the horizontal bearing pin 3-4 a pair with internal thread hole being each passed through elastic component 4-B a pair level perforation 4-4, be connected with involutory two another 3-4 of shell involutory after, be connected by the two trip bolt 3-2 penetrated from outside.
The electric hand drill of the present embodiment is connected with being connected mutually to be interted by the Connection Block and the pin shaft structure of self with elastic component between shell due to handle shell; therefore not only there is desirable vibration isolating effect; practical protective effect can be played to the power brick of bottom; and bonding strength and reliability significantly strengthen; even if be subject to impacting external force; also can not throw off, and ensure that the use safety of electric drill.
In addition to the implementation, the present invention can also have other embodiments.Such as, obviously also handle shell can be connected with elastic component and connect the equivalent structure that shell is connected with rigid member; And for example, the syndeton of elastic fin and vibration isolation sheet also can adopt the both sides of elastic component to extend horizontally away elastic fin respectively, and two involutory handle shells have the structure of the sheet of vibration isolation up and down blocking corresponding elastic fin respectively; For another example, rigid member and elastic component only have a manhole respectively is also feasible; Or after serving as a contrast one deck elastomeric material in the level of rigid member perforation 4-3, penetrate horizontal bearing pin 1-3 again, thus increase elastic buffer link, strengthen vibration isolating effect further; Etc..All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
