CN201654485U - Air-permeable wristwatch bottom cover - Google Patents

Abstract

The utility model relates to the technical field of clocks, in particular to an air-permeable wristwatch bottom cover, which comprises a bottom cover, a plurality of raised strips, annular grooves and two radial grooves, wherein the raised strips are arranged on the bottom cover and integrated therewith, and adopt a plurality of ring-shaped metal strips concentric with the bottom cover; the outermost raised strip is divided into eighths by eight gaps uniformly distributed at the circumference of the raised strip; the rest raised strips are all divided into quarters by four gaps uniformly distributed at the circumferences of the raised strips; the gaps at the circumferences of the raised strips are aligned in the diameter direction of the bottom cover and form the two orthogonal radial grooves; and each annular groove adopts a ring-shaped gap between the edges of two adjacent raised strips, and the widths of the annular grooves, the radial grooves and the raised strips are identical. The utility model avoids the dampness of the bottom of a wristwatch due to sweat aggregation, thereby improving the comfort of the wrist when a user wears the wristwatch.

Description

The permeability type bottom cover of watch

Technical field

The utility model relates to the clock and watch technical field, particularly relates to a kind of permeability type bottom cover of watch.

Background technology

Existing wrist-watch, its chassis is generally smooth plane, it is isolated that such structure causes being close to the skin and the air of wrist portion on chassis, therefore, the sweat that pore is discharged can't evaporate, particularly during the broiling summer, can make the people feel that skin is very uncomfortable, simultaneously, so just increase the moisture at wrist joint place, also influenced health.

The utility model content

The utility model provides a kind of ventilated function that has for solving the deficiencies in the prior art, can increase simultaneously wrist portion skin comfort the permeability type bottom cover of watch.

The scheme that solves the utility model technical matters is: the permeability type bottom cover of watch is made of bottom, raised line, ring groove and radial slot.Wherein, the bottom surface of bottom is the plane, have on the bottom many projectioies, with bottom be holistic raised line.Raised line is the endless metal bar of multi-turn and bottom concentric, the thickness of each circle raised line is 2-4mm, width is the 1/10-1/14 of bottom diameter, the raised line of outmost turns by eight along the equally distributed gap of raised line circumference with its eight equal parts, remaining raised line all by four along the equally distributed gap of the raised line circumference quartern.Gap on described each raised line circumference is in the alignment of the diametric(al) of bottom and constitute two mutually orthogonal radial slots.Ring groove is the annular space between the edge of adjacent two raised lines, and the width of ring groove, radial slot and raised line all equates.

Adopt such scheme, can reach following effect:

When the utility model contacts with wrist skin, the sweat gas that skin is discharged can be pooled in the radial slot of two quadratures and in time discharges from the end of radial slot by ring groove, cause the wrist-watch bottom moist with regard to having avoided owing to the gathering of sweat gas like this, thereby improved the comfort level of wrist when wearing table, also helped the health of wrist.

Description of drawings

Fig. 1 is a planar structure synoptic diagram of the present utility model;

Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.

Among the figure: 1. bottom 2. raised lines 3. ring grooves 4. radial slots

Embodiment

The utility model will be further described below in conjunction with drawings and Examples.

The permeability type bottom cover of watch is made of bottom 1, raised line 2, ring groove 3 and radial slot 4.Wherein, the bottom surface of bottom 1 is the plane, have on the bottom 1 many projectioies, be holistic raised line 2 with bottom 1.Raised line 2 is endless metal bars of multi-turn and bottom 1 concentric, the thickness of each circle raised line 2 is 2-4mm, width is the 1/10-1/14 of bottom 1 diameter, the raised line 2 of outmost turns by 8 along the equally distributed gap of raised line 2 circumference with its eight equal parts, remaining raised line 2 all by four along the equally distributed gap of the raised line 2 circumference quartern.Gap on described each raised line 2 circumference is in the alignment of the diametric(al) of bottom 1 and constitute two mutually orthogonal radial slots 4.Ring groove 3 is the annular space between the edge of adjacent two raised lines 2, and the width of ring groove 3, radial slot 4 and raised line 2 all equates.

Claims (1)

1. a permeability type bottom cover of watch is by bottom, raised line, ring groove and radial slot constitute, it is characterized in that: the bottom surface of bottom is the plane, many projectioies are arranged on the bottom, with bottom be holistic raised line, raised line is the endless metal bar of multi-turn and bottom concentric, the thickness of each circle raised line is 2-4mm, width is 1/10 of a bottom diameter---1/14, the raised line of outmost turns by eight along the equally distributed gap of raised line circumference with its eight equal parts, remaining raised line all by four along the equally distributed gap of the raised line circumference quartern, gap on described each raised line circumference is in the alignment of the diametric(al) of bottom and constitute two mutually orthogonal radial slots, ring groove is the annular space between the edge of adjacent two raised lines, ring groove, the width of radial slot and raised line all equates.
