Description

The platform scale opened and rinse can be promoted

Technical field

The present invention relates to platform scale.

Background technology

Platform scale is the electronic scale between platform balance and truck scale, and the difference according to weighing object value is divided into: plain edition, middle precision type and high-precision flat platform balance.Be divided into again plain edition and explosion-proof shape platform scale according to environment for use simultaneously.Along with the development of enterprise, platform scale is widely used in the links produced.Existing flushable platform scale only scale body upper flat plate is opened, and framework easily has dead angle, exists and rinses halfway problem.

Summary of the invention

The object of the present invention is to provide and a kind ofly can promote the platform scale opened and rinse, the framework of its scale body and dorsal part thereof all can be rinsed.

The platform scale opened and rinse can be promoted for what realize described object, comprise the framework of scale body and scale body dorsal part, it is characterized in that, also comprise hoisting gear and locking mechanism, this hoisting gear comprises air spring and holder, locking mechanism comprises lock handle and dead-man's handle, be respectively arranged with this hoisting gear to arrange and this locking mechanism in the both sides of one end of framework, this end of framework and holder hinged, one end hinged frame of air spring, the hinged holder of the other end, handle is hinged on holder, handle has catching groove, the first lock pin on the catching groove of handle and framework coordinates lockable framework to be in open mode, dead-man's handle has microscler chute, the upside of chute has multiple ratchet, the second lock pin on framework is inserted with in chute, this second lock pin snaps in described ratchet, the framework reversing be opened can be prevented.

Scale body and framework are opened by air spring power-assisted, air spring according to ergonomic, preferred arrangement lifting body accurate Calculation, whole process thrust is less than body burden all the time, guarantees single can easily opening; Scale body and framework are strutted completely by air spring, can this electronic platform scale of cleaning down, have the client of high request more and more attractive to flushing and health, meet its high efficiency, functional, simultaneously for operator, and simple to operate, light, safety.

Fig. 2 is the decomposing schematic representation promoting the platform scale opened and rinse.

Fig. 3 is the close-up schematic view at Z place in Fig. 1.

Embodiment

As shown in Figure 1 to Figure 3, in an embodiment of the present invention, for a ultralow table top electronic platform scale, this platform scale comprises and draws slope 1, scale body 2, hoisting gear 4, LOAD CELLS 7, terminal box 3 and Displaying Meter 5.Scale body 2 is welded to form by table top 2-1 and gusset 2-2, and stainless steel table top 2-1 is integrated bending and molding, and all gusset 2-2 adopt open welding.Four LOAD CELLS 7 are arranged on the sensor installing plate in four bights of scale body 2 respectively, are connected with holder 4-1 by sensor foot 7-1.

Special in Fig. 3, hoisting gear 4 comprises holder 4-1, air spring 4-5.Hoisting gear 4 has setting respectively in the both sides of the first end (right-hand member of Fig. 1, the left end of Fig. 2) of framework 4-4.Holder 4-1 is connected on basis, it has the installing plate 4-2 being convenient to connect, the hinged holder 4-1 in one end of air spring 4-5, other end hinged frame 4-4, the end of framework 4-4 is hinged with holder 4-1, when air spring 4-5 extends completely, the framework 4-4 of scale body 2 and dorsal part thereof is opened to extreme higher position by lifting.

Corresponding hoisting gear 4, be also respectively arranged with locking mechanism in the both sides of the first end of framework 4-4, locking mechanism comprises lock handle 4-7 and dead-man's handle 4-6.Lock handle 4-7 is hinged on holder 4-1, it there is the catching groove 471 of arc, rotation direction when lock handle 4-7 is to open in contrast to framework 4-4 and rotating, to make catching groove 471, the first lock pin 441 on framework 4-4 is included in, once the first lock pin 441 enters into catching groove 471, if the power that framework 4-4 has the trend that is opened to produce, the first lock pin 441 and lock handle 4-7 will fastenings mutually, thus prevent framework 4-4 and on scale body 2 be opened.In other embodiments of the present utility model, by means of securing member or keeper, lock handle 4-7 can be fixed or the spacing position at locking framework 4-4, or lock handle 4-7 is remained on can lock the position of the first lock pin 441 by spring, to increase security further.

As shown in Figure 3, dead-man's handle 4-6 is hinged on holder 4-1, there is microscler chute 461, there are three ratchets 462 upside of chute 461, and the second lock pin 442 on framework 4-4 is arranged in chute 461, is stuck in ratchet 462, make framework 4-4 can only turn clockwise (rotation direction namely opened), and can not rotate backward, even if like this when air spring lost efficacy, the flushing of platform scale was also safe.When needs put down scale body 2, rotate counterclockwise dead-man's handle 4-6, to make the second lock pin 442 can slide in chute 461, scale body 2 and framework 44 thereof so just can be made to rotate counterclockwise and be put down.

When scale body 2 puts down, adjustment scale body 2 to certain gap with framework 4-4, makes four sensor foot 7-1 to a certain degree to freely swing, reaches the object of weighing.Hoisting gear 4 starts, and comprises the whole weighing platform of scale body and starts thereupon, directly rinses to ground, more thoroughly.Terminal box 3 is arranged on the side of scale body 2 bending table top, and terminal box itself possesses the function of erosion control, open placement, there will not be cleaning dead angle.The web member installing plate etc. of holder 4-1 on it is fixed on ground by expansion bolt.When air spring 4-5 is compressed, guarantee that the leg of scale body 2 falls within web member holder, the position of adjustment left and right lock handle 4-7, and locked left and right handle of whipping, load weighs via drawing slope 1 or being directly positioned over table top; Ensure that left and right pressing plate 4-8 tightens, decontrol left and right handle 4-7, air spring 4-5 and extend, whole table top is opened, and dead-man's handle 4-6 has third gear safety locking mechanism, duplicate protection personal safety simultaneously; There is gib screw 4-9 spacing between scale body 2 and framework 4-4, LOAD CELLS 7 connects the input end of terminal box by cable, the cable aperture that the signal shielding cable 6 being connected to terminal box output terminal passes on scale body, on framework is connected with Displaying Meter 5, is spread out of by weight signal.
