Abstract

The objective of the invention is to provide a platform scale capable of being lifted, opened and flushed. A scale body of the platform scale and a frame of a reverse side of the platform scale can be flushed. In order to realize the platform scale capable of being lifted, opened and flushed, the platform scale capable of being lifted, opened and flushed comprises the scale body and the frame of the reverse side of the scale body. The platform scale capable of being lifted, opened and flushed is characterized by further comprising a lifting mechanism and a locking mechanism. The lifting mechanism comprises an air spring and a fixing seat. The locking mechanism comprises a locking handle and a safety handle. Two sides of one end of the frame are respectively provided with the lifting mechanism and the locking mechanism. The end of the frame is hinged with the fixing seat. One end of the air spring is hinged with the frame, and the other end is hinged with the fixing seat. The handles are hinged on the fixing seat and provided with buckling grooves. The buckling grooves of the handles are matched with first lock pins on the frame so that the frame is at the opening state through locking. The safety handle is provided with a long slide groove, and the upper side of the slide groove is provided with multiple ratchets. Second lock pins on the frame are inserted into the slide groove, and the second lock pins are clamped into the ratchets so that the opened frame can be prevented from being reversed.

Description

Can promote the platform scale of opening and rinsing

Technical field

The present invention relates to platform scale.

Background technology

Platform scale is the electronic scale between platform balance and truck scale, is divided into: plain edition, middle precision type and high-precision flat platform balance according to the difference that weighs object value.According to environment for use, be divided into again plain edition and explosion-proof shape platform scale simultaneously.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 dead angle, has the halfway problem of rinsing.

Summary of the invention

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

For what realize described object, can promote the platform scale of opening and rinsing, 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 in one end of framework are respectively arranged with this hoisting gear setting and this locking mechanism, this end of framework and holder are 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 in open mode, on dead-man's handle, there is microscler chute, the upside of chute has a plurality of ratchets, in chute, be inserted with the second lock pin on framework, this second lock pin snaps in described ratchet, can prevent the framework reversing being opened.

Scale body and framework are opened by air spring power-assisted, and air spring is according to ergonomic, preferred arrangement lifting body accurate Calculation, and 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, to rinsing and health has the client of high request more and more attractive, meet its high efficiency, functional, and simultaneously for operator, simple to operate, light, safety.

Fig. 2 is the decomposing schematic representation that promotes the platform scale of opening and rinsing.

Fig. 3 is the local enlarged diagram at Z place in Fig. 1.

Embodiment

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

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 basis, it has the installing plate 4-2 of being convenient to connect use, 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 raised and is opened to extreme higher position.

Corresponding hoisting gear 4, is also 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 holder 4-1, the catching groove 471 that has arc on it, the rotation direction of lock handle 4-7 when opening in contrast to framework 4-4 and rotating, so that catching groove 471 is included the first lock pin 441 on framework 4-4 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 fastening mutually, thereby prevent framework 4-4 and on scale body 2 be opened.In other embodiments of the invention, can lock handle 4-7 be fixed or the spacing position at locking framework 4-4 by means of securing member or keeper, or by spring, make lock handle 4-7 remain on the position that can lock the first lock pin 441, further to increase security.

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

When scale body 2 puts down, adjust scale body 2 gap extremely certain with framework 4-4, four sensor leg 7-1 can to a certain degree be freely swung, reach the object of weighing.Hoisting gear 4 starts, and comprises that the whole weighing platform of scale body starts thereupon, directly rinses to ground, more thorough.Terminal box 3 is arranged on a side of scale body 2 bending table tops, and terminal box itself possesses the function of erosion control, and open placement there will not be and cleans dead angle.Holder 4-1 web member installing plate on it etc. 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, adjust the position of left and right lock handle 4-7, and the locked left and right handle of whipping, load weighs via drawing slope 1 or being directly positioned over table top; Guarantee that left and right pressing plate 4-8 tightens, decontrol left and right handle 4-7, air spring 4-5 extends, and whole table top is opened, and dead-man's handle 4-6 has third gear safe lock mechanism, duplicate protection personal safety simultaneously; Between scale body 2 and framework 4-4, there is gib screw 4-9 spacing, 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 scale body, on framework and be connected with Displaying Meter 5, weight signal is spread out of.
