Description

Can promote the platform scale of opening and washing

Technical field

The utility model relates to platform scale.

Background technology

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

The utility model content

The purpose of this utility model is to provide a kind of can promote the platform scale of opening and washing, and the framework of its scale body and dorsal part thereof all can be rinsed.

Can promote the platform scale of opening and washing for what realize described purpose, the framework that comprises 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, both sides at an end of framework are respectively arranged with this hoisting gear setting and this locking mechanism, this end of framework and holder are hinged, an end hinged frame of air spring, the hinged holder of the other end, handle is hinged on the holder, handle has catching groove, and the first lock pin on the catching groove of handle and the framework cooperates the lockable framework to be in open mode, has microscler chute on the dead-man's handle, the upside of chute has a plurality of ratchets, be inserted with the second lock pin on the framework in the chute, this second lock pin snaps in described ratchet, can prevent the framework reversing that is opened.

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

Embodiment

As shown in Figure 1 to Figure 3, in embodiment of the present utility model, take a ultralow table top electronic platform scale as example, 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 installed in respectively on the installation of sensors plate in four bights of scale body 2, are connected with holder 4-1 by sensor leg 7-1.

With reference to Fig. 3, hoisting gear 4 comprises holder 4-1, air spring 4-5 especially.Hoisting gear 4 has respectively setting 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 the basis, it has the installing plate 4-2 of being convenient to connect usefulness, the hinged holder 4-1 of the 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 extended fully, the framework 4-4 of scale body 2 and dorsal part thereof was raised and is opened to the extreme higher position.

Corresponding hoisting gear 4 also is respectively arranged with locking mechanism in the both sides of the first end of framework 4-4, and locking mechanism comprises lock handle 4-7 and dead-man's handle 4-6.Lock handle 4-7 is hinged on the holder 4-1, the catching groove 471 that arc is arranged on it, lock handle 4-7 when opening in contrast to framework 4-4 rotation direction and rotate, so that catching groove 471 is included the first lock pin 441 on the framework 4-4 in, in case 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 mutually fastening of lock handle 4-7, thereby prevent framework 4-4 and on scale body 2 be opened.In other embodiment of the present utility model, can lock handle 4-7 be fixed or spacing position at locking framework 4-4 by means of securing member or keeper, perhaps by spring so that lock handle 4-7 remains on the position that can lock the first lock pin 441, with further increase security.

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

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