The utility model has the main improvement point that a display disc is arranged at the right front part of a balance pan has double-face display, a single metering spring is used for connecting a threaded rod and a connecting ring, a transmission rod is provided with a frame shape and is hinged on a support frame through a shaft, a movable hook is additionally arranged between a connecting rod and a power point ring, a preloaded spring is arranged under a bearing plate, a bayonet pin and a spring sheet are arranged on the bearing plate and at the contact point of bearing plate and the support frame, the bayonet pin is tightly next to the support frame when the utility model is unfolded, and the balance head part is folded into 90DEG by pressing the bayonet pin. The utility model has the advantages of novel design, compact structure, easy adjustment, exact measure and convenient carrying.

Description

Foldable double-sides spring scale scale

The utility model relates to a kind of spring scale scale.

The domestic and international at present spring scale scale of producing, mostly be a top or a side of the scale pan of splendid attire thing being located at scale, see weigh not too convenient, and have only a flat-panel display device, be inconvenient to more when client does shopping see alleged weight, add that volume ratio is bigger, can not fold again, therefore, carry inconvenience, be not suitable for very much mobile street pedlar and use.

The purpose of this utility model provides a kind of Foldable double-sides spring scale scale.Its energy double-sided display can fold, and volume is little, in light weight, accurate measurement.

Below in conjunction with accompanying drawing the utility model Foldable double-sides spring scale is claimed to carry out detailed narration:

Accompanying drawing 1 is a contour structures synoptic diagram of the present utility model.

Accompanying drawing 2 is structure principle charts of the present utility model.

Accompanying drawing 3 is structural representations of the present utility model.

Accompanying drawing 4 is topology views of the utility model scale head part.

Accompanying drawing 5 be among Fig. 4 A--A to view.

With reference to the accompanying drawings shown in 1,2,3, the utility model Foldable double-sides spring degree Pan scale partly is made of scale head part, load-bearing, scale head part comprise display panel (1), Pointer (2), zeroing nut (3), screw rod (4), metering spring (5), tooth bar (6), Gear (7), bimetal leaf (8), connecting ring (9), drive link (10), connecting rod (11) Form. Load-bearing partly comprise force ring (12), lever (13), two levers (14), in Thimble (15), fulcrum ring (16), bearing plate (17), cutter (18), cutter hold (19), the end Seat (20), the scale pan (21), support (22), support plate (25) consist of. It improves main points: The first is located at the dead ahead of the scale pan (21) and two-sided with the display panel (1) of scale head part Show that pointer (2) is two, be difficult for cheating when weighing like this, client does shopping relieved. It two adopts single metering spring (5) to be connected at screw rod (4) and connecting ring (9), like this It is very easy that metering spring is adjusted weighing, and be provided with not temperature influence of temperature compensator, Make simple in structurely, debugging assembling easily. It three is that drive link (10) design is frame shape Shape also is hinged on the support (22) with axle (23), like this, so that drive link (10) can only Swing up and down and to move forward and backward, guaranteed the precision of weighing, shown in Fig. 4,5. Its four between connecting rod (11) and force ring (12) activity of setting up collude (24), make scale When head part folded, metering spring (5) did not overlap elongation. It is five below support plate (25) Preloaded spring (26) is set, and preloaded spring (26) one ends connect bearing plate (17), so that Bearing plate (17) has certain load when zero load, thus make cutter hold (19) and blade it Between in uncharge situation, can keep good contact. Its six support plate (25) upper with The contact site of support (22) arranges bayonet lock (28) and shell fragment (29), and commissure axle (27) is established On support and depart from scale head central axis, bayonet lock (28) is not near support when folding (22) as shown in Figure 3, press bayonet lock (28) and can be folded into 90 degree to scale head part, again will The scale pan (21) left-hand thread is box-like, easy to carry at scale head one-tenth one. During use, with the scale head Partly upright, bayonet lock (28) borrows the strength of shell fragment (29) automatically to block.

The utlity model has modern design, compact conformation, easy, the metering standard of adjustment Really, advantage easy to carry.
