[0019] 下面结合具体实施例对本发明作进一步详细说明; [0019] The following embodiments in conjunction with the specific embodiments of the present invention will be described in further detail;

实施例1,如图1图2所不,一种陶瓷背板防水手表,包括表壳I,表壳I内安装的表盘,通过螺丝装配在表壳I底部的底盖2,该底盖2包括开设有螺孔3的金属圈4,在金属圈4的正面内环圆周开环形凹槽5,以及通过热胀冷缩方式紧密嵌套在凹槽5内的陶瓷背板6。 Example 1, as shown in FIG. 2 is not a waterproof backsheet ceramic watch case comprising I, I mounted inside the case of the embodiment of the dial, the bottom cover by means of screws at the bottom of the case assembly I, 2, the cap 2 defines a ring comprising a metal screw 3 of 4, 4 in front of the eyelet opening and the inner circumference of the annular groove 5, and a ceramic backing plate closely nested within the recess 5 by thermal expansion and contraction of the 6 ways.

[0020] 实施例2,如图3图4所示,在金属圈4与环形凹槽5相对的反面整体成型有环形凸棱7,且该环形凸棱7的外径小于表壳I底部内径;这种结构的好处是:起到定位的作用,使得装配上变得更加方便。 [0020] Examples 2, 3 and 4, the metal ring 4 and the annular groove 5 formed integrally with a back opposite the annular rib 7, and the outer diameter of the annular rib 7 is smaller than the inner diameter of the bottom of the case I ; the advantage of this structure are: play the role of positioning, so that the assembly becomes easier.

[0021] 且该金属圈4的厚度由内至外逐渐减小;这种结构的好处是:一方面使得整体结构更为紧凑,另一方面减小螺丝的长度,紧固更可靠。 [0021] and a thickness of the metal ring 4 is gradually reduced from the inside to the outside; The advantage of this configuration is: on the one hand makes the whole structure more compact, on the other hand to reduce the length of the screw, the fastening is more reliable.

[0022] 凹槽5的直径小于陶瓷背板6的直径,且凹槽5的深度比陶瓷背板6的厚度小0.1Omm ;这种结构的好处是:便于安装,以及确保金属圈4正面内环与陶瓷背板6平整,方便配合安装达到密封的效果。 Diameter [0022] The groove 5 is less than the diameter of the ceramic backing plate 6, and the groove depth smaller than the thickness of the ceramic 5 backsheet 6 0.1Omm; The advantage of this structure are: ease of installation, and to ensure that the front metal ring 4 flat backing plate 6 and the ceramic ring, to seal the installation fitting to facilitate effect.

[0023] 实施例3,如图5所示,在环形凸棱7与表壳I之间设置防水圈8更加强了密封的可靠性。 [0023] Example 3, as shown in Figure 5, the waterproof ring is provided between the case and the annular rib 7 I 8 reliability of the seal is reinforced.

[0024] 实施例4,如图6所示,在陶瓷背板6和凹槽5之间图上粘合剂9同样也是确保密封可靠。 [0024] Example 4, as shown in FIG. 6, FIG adhesive on the backing plate 6 between the ceramic and the recess 59 is also to ensure reliable sealing.

[0025] 金属圈4和陶瓷背板6紧密嵌套的步骤如下: [0025] Ceramic metal ring 4 and the backing plate 6 tightly nested steps:

(1)制作凹槽5直径为a的金属圈4,在金属圈4与环形凹槽相对的另一面整体成型有环形凸棱7,以及尺寸在1.25al.5a收缩率为20%的陶瓷背板泥坯; (1) Preparation of a diameter of the recess 5 of the metal ring 4, the other surface of the metal ring opposite the annular groove 4 formed integrally with an annular rib 7, and a dimensional shrinkage rate of 20% in the ceramic back 1.25al.5a mud plate;

(2)用1200-1400°C的高温煅烧陶瓷背板泥坯20-40min,烧完尺寸为a_l.2a之间,打磨烧结好的陶瓷背板6至直径在a-1.0112a之间; (3)用高温对金属圈4进行加热5-15min ; (2) the temperature 1200-1400 ° C calcined ceramic backplate mud 20-40min, burn dimension between a_l.2a, good ceramic sintered polished to a diameter between the backing plate 6 a-1.0112a; ( 3) heating the metal ring 4 5-15min high temperature;

(4)将打磨好的陶瓷背板6放入凹槽5内,待金属圈4冷却至常温即可实现金属圈4和陶瓷背板6间过盈配合; (4) The buffed ceramic backing plate 6 into the recess 5, the metal ring 4 to be cooled to room temperature and 4 can be realized a ceramic eyelet interference fit back plate 6;

实施例5,我们取凹槽5直径为3.2cm的金属圈4,以及直径4.1cm的陶瓷背板泥坯,用1000C的高温煅烧陶瓷背板泥坯30min,实测烧结后的陶瓷背板6直径为3.28cm,打磨烧结好的陶瓷背板6至直径为3.21cm ;用700°C的高温对金属圈4进行加热1min,此时金属圈4的热膨胀系数为0.000016m / K,将原先直径3.2cm的金属圈4热膨胀为直径3.23cm,然后再把打磨烧结好的陶瓷背板6放置于加热的金属圈4中,待其冷却即可。 Example 5 embodiment, we take the recess 5 of 3.2cm diameter metal ring 4, and 4.1cm diameter ceramics backplane mud, 30min, measured after sintering the ceramic backing plate with a diameter of 6 Calcined ceramic backplate of mud 1000C of 3.28cm, a good polished sintered ceramic to the backing plate 6 having a diameter of 3.21cm; 1min metal ring is heated by a high temperature of 700 ° C 4, when the thermal expansion coefficient metal ring 4 is 0.000016m / K, the original diameter 3.2 4 cm eyelet thermal expansion of diameter 3.23cm, and then grinding the ceramic sintered good backsheet 6 is placed in a heated metal beads 4, to let it cool.

[0026] 结构原理:加热金属圈4,本发明中700°C对应不锈钢热膨胀系数为0.000016m /K,待加热之后,金属圈4膨胀开来,再把原本无法放入凹槽5区域的陶瓷背板6放入其中,待金属圈4冷却后,收缩将陶瓷背板6封紧,实现陶瓷背板6跟金属圈4的过盈配合,从而使得密封可靠。 [0026] Structural principle: heating the metal ring 4, the present invention is 700 ° C corresponding to a thermal expansion coefficient of stainless steel 0.000016m / K, then to be heated, the metal ring 4 is expanded to open, then the original can not be placed in the recess 5 of ceramic region 6 backplane into which, after being cooled, the metal ring 4, the shrinkage of the ceramic backing plate 6 tight, interference fit with the ceramic backing plate 6 of metal ring 4, so that reliable sealing.
