Specific embodiment

To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the attached drawing in embodiment, to reality The technical solution applied in example is clearly and completely described,

A kind of luggage weighing foot, is fixed on luggage shell 10, and weighing foot is split type structure, and it includes outsides to weigh Component 30 and internal weigh assembly 20, external weigh assembly 30 and internal weigh assembly 20 are located at the outside of luggage shell 10 It is pressed abd fixed on luggage shell 10 with what internal and the two was engaged；

External weigh assembly 30 includes to claim foot lid 31 and weighing briquetting 32, and foot lid 31 is claimed to have a vertical perforative channel 311, weighing briquetting 32 is accepted in channel 311 and can move axially along channel 311, and the lower end of weighing briquetting 32 is exposed to title The bottom surface of foot lid 31 and the bottom surface for being not less than title foot lid 31；

Internal weigh assembly 20 includes upper cover 22 and lower cover 23, pressure sensor 24 and briquetting connecting rod 25, upper cover 22 And lower cover 23 fastens the cavity 21 for being formed between the latter two and accommodating pressure sensor 24, pressure sensor 24 is accepted in the cavity In 21；One briquetting connecting rod 25 passes through luggage shell 10, the lower end of briquetting connecting rod 25 and the upper-end contact of weighing briquetting 32, Upper end is pushed against in pressure sensor 24 by pressure side 241.

Briquetting connecting rod 25 is overlapped with weighing 32 axis of briquetting, and axis is overlapped the precision that weighing can be improved.

The upper end of briquetting connecting rod 25 has a limiting section 251, and lower cover 23 has one to lead to for what briquetting connecting rod 25 passed through The size in hole 231, limiting section 251 is greater than through-hole 231, so that limiting briquetting connecting rod 25 carries out axial limiting, prevents its abjection.

A supporting block 252 is fixed at the top of limiting section 251, supporting block 252 is contacted with pressure sensor by pressure side 241.

When luggage weighing, weighing briquetting 32 drives briquetting connecting rod 25 to move up the compression for making pressure sensor End 241 above pushes away to generate deformation, and preferably pressure sensor is one spherical by the contact surface of pressure side 241 and supporting block 252 Face good can guarantee to be contacted and protected with supporting block 252 always by pressure side 241 during by 241 deformation of pressure side It demonstrate,proves contact point on its axis, improves measurement accuracy.

There is the position-limit mechanism of the limitation of briquetting 32 inside it that will weigh in channel 311.

Position-limit mechanism by the limiting stand 312 in channel 311 and be fixed on weighing 32 circumferential surface of briquetting multiple elastic spacings Pawl 322 forms, and has retention bead 323 on elastic spacing pawl 322, and retention bead 323 is limited platform 312 and stops to limit title Weight block 32 is in setting range activity.

The upper end of weighing briquetting 32 has a groove 321 being embedded in for the lower end of briquetting connecting rod 25, briquetting connecting rod 25 Mobilizable to be embedded in the groove 321,321 bottom of groove has a support portion 323, and support portion 323 withstands on briquetting connecting rod 25 lower ends.

Claim the upper surface of foot lid 31 that there are multiple positioning protrusion 34 upwardly extended, luggage shell 10 and lower cover 23 are distinguished With location hole 12 corresponding with positioning protrusion 34 and dimple 232, upper cover 22 is pacified with screw corresponding with positioning protrusion 34 Hole 221 is filled, positioning protrusion 34 is inserted into dimple 232 after passing through location hole 12, the under shed of screw installing hole 221 and fixed Position nest 232 is connected to, and screw is tightened in positioning protrusion 34 after penetrating screw installing hole 221 and location hole 12 by outer weigh assembly 30 and interior weigh assembly 20 be fixedly connected on luggage shell 10.

In addition, pressure sensor is changed to doubling and is connect with patching with circuit board, more conducively its cabling and installation connects It connects.

Specific working principle are as follows:

When installation, by outer weigh assembly 30 and interior weigh assembly 20 outwardly and inwardly filling from luggage shell 10 respectively Match, positioning protrusion 34 is caught in location hole 12, dimple 232 is aligned with positioning protrusion 34 and is caught in, is inserted into spiral shell using screw Silk mounting hole 221 is simultaneously tightened in positioning protrusion 34, includes titles foot lid 31 and briquetting of weighing due to outer weigh assembly 30 32, so its volume can be made small, so that the foot cover volume outside luggage is substantially reduced, and interior weigh assembly 20 is put Pressure sensor can also be further protected in luggage, it is avoided to be damaged.

When weighing, the pressure that weighing briquetting will be subject to is applied to pressure sensor by briquetting connecting rod and supporting block Force side makes it generate deformation, and deformation is converted to the variable of electric signal, is transmitted at processor by signal wire by pressure sensor Reason, to show its weight amount over the display.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
