Description

Novel portable electronic scale

Technical field

The utility model belongs to electronic scale technical field, specially a kind of novel portable electronic scale.

Background technology

It is well known that the sensor almost all of traditional Portable electronic scale uses beam type resistance strain sensor, this Kind sensor is in dynamometry, it is desirable that the direction of stress is vertical with the horizontal direction of strain beam.When portable weigh, gravity direction begins It is that vertically downward, this requires sensor is necessarily mounted at a fixing bracket eventually（Electronic scale sunpender）On, and strain beam In horizontal plane.When electronic scale is used to weigh object, it is also necessary to strain beam is remained in the horizontal plane, so that standard of weighing Really, as shown in Figure 1.

However, due to structure problem, user is mostly to hold portable scale to operate when using electronic scale, it is difficult to ensure that Strain beam is in absolute horizon, but more or less makes scale body that different degrees of inclination occur with the custom of user's operation, this When, due to generating a component between gravity and strain beam, weight cannot be completely reacted on the force sensing element on strain beam, by This will generate larger error, and caused error is uncertain, and inclination angle is bigger, and error is bigger.In portable electricity Error is particularly evident in sub- scale particularly cross handle travelling scale, and this error is inevitable.

Utility model content

To solve existing Portable electronic scale run-off the straight in use, prevent the strain beam in electronic scale from water Plane, the problem of leading to error, the utility model provide a kind of novel portable electronic scale.The utility model is novel using one kind The stent of rotatable fixed sensor and the power conductive process generated, form a kind of completely new Portable electronic scale weighing group Part thoroughly solves the problems, such as the uncertain error caused by Portable electronic scale tilts so that electronics using the weigh assembly When scale uses in a certain range（Positive and negative 30 °）It tilts, does not influence weighing accuracy.

To achieve the above object, the technical solution adopted in the utility model is：

Novel portable electronic scale, including handle, housing, weigh assembly, handle is connect by hanging ring with housing, housing packet Bottom case is included, bottom case includes front casing and rear casing, hollow hard axle sleeve is respectively fixedly installed on front casing and rear casing inner surface, Weigh assembly is equipped in housing, the weigh assembly includes upper lacing film, lower lacing film, sensor and hook, upper lacing film and lower lacing film Respective one end coordinated by nut and screw and fix sensor, the other end connection hook of lower lacing film, upper lacing film it is another Both sides is held to be equipped with protruding shaft, protruding shaft both ends are inserted into respectively in the hard axle sleeve on front casing and rear casing inner surface, and protruding shaft is in hard It can be rotated in axle sleeve.

Preferably, the longitudinal section of the protruding shaft is round or diamond shape.

Preferably, it is hollow cylinder in the hard axle sleeve.

Preferably, front casing is equipped with display screen, and the lower section of display screen is equipped with button, tape measure is additionally provided in housing.

Compared with prior art, the beneficial effects of the utility model are：

The utility model utilizes one end both sides of upper lacing film in weigh assembly to be equipped with protruding shaft, and protruding shaft is round or diamond shape, will Protruding shaft is put into the hard axle sleeve on the front and rear casing of portable electronic balance housing, and protruding shaft is rotatable in hard axle sleeve, exists in this way Using during run-off the straight, strain beam is in horizontal position during portable electronic balance, weighing will not generate error, solve existing Error problem caused by run-off the straight when having portable electronic balance use, so as to ensure that weighing accuracy.

Specific embodiment

Purpose, technical scheme and advantage to make the utility model embodiment are clearer, new below in conjunction with this practicality Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

In the description of the present invention, it should be noted that term " interior ", " outer ", " on ", " under ", "left", "right", The orientation or position relationship of the instructions such as "front", "rear" are under Portable electronic scale normal operating condition, and display screen is towards user Position come what is defined, be for only for ease of description the utility model and simplify description rather than instruction or imply signified dress It puts or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that the utility model Limitation.

It is one embodiment that the utility model proposes portable electronic balance refering to Fig. 2 ~ Fig. 5, in the present embodiment, hand It carries formula electronic scale and includes handle 1, housing, weigh assembly three parts, handle 1 is connect by hanging ring 2 with housing, and housing includes bottom Shell 3, bottom case 3 include front casing and rear casing, and front casing is equipped with display screen 4, and the lower section of display screen 4 is equipped with button 5, in housing Tape measure 6 is additionally provided with, hollow hard axle sleeve 7 is respectively fixedly installed on front casing and rear casing inner surface, weighing group is equipped in housing Part.

Refering to Fig. 3, in the present embodiment, weigh assembly includes upper lacing film 8, sensor 10, lower lacing film 12 and hook 13, upper extension Sensor 10 is fixed by nut 9 and screw 11 in respective one end of piece 8 and lower lacing film 12, and the other end connection of lower lacing film 12 is hung Hook 13.Refering to Fig. 4, in the present embodiment, the other end both sides of upper lacing film 8 are equipped with protruding shaft 8-1, and the both ends of protruding shaft 8-1 are inserted into respectively In hollow hard axle sleeve 7 on the front casing and rear casing inner surface of housing, protruding shaft 8-1 can rotate in hard axle sleeve 7, hard It is hollow cylinder in axle sleeve 7.In the present embodiment, the longitudinal section of protruding shaft 8-1 is round or diamond shape.When round or diamond shape protruding shaft with When hard axle sleeve coordinates, contacted with tangent line or water chestnut line with hard axle sleeve inner headed face, gravity is made to pass through upper lacing film and concentrates on one Housing is conducted on " line ".Weight transmitting is given by the handle that housing is connected by housing.Left bank or the right side occurs in electronic scale During inclination, strain beam still maintains horizontal, so as to ensure that weighing accuracy.The weigh assembly can be used for portable scale or other On suspending electronic balance.
