Description

Case

technical field

The utility model relates to a watch, in particular to a watch case.

Background technique

Existing hard plastic watches and bracelet watches are favored by young friends because of their simple structure, low price, attractive appearance and fashion. This kind of watch is directly through the tight combination of the upper watch case and the bottom cover to realize the fixing and sealing of the movement, and at the same time achieve the waterproof function. And the combination between the upper watch case and the bottom cover of the existing watch is realized by screws or mutual tightening, wherein the watch case fixed in the tightening mode tends to have different bursting cracks due to different points of forced force, which is serious. Affect the appearance and waterproof function. Simultaneously, because the material used in this watch is engineering plastics (such as acrylic and PC materials), it has unbearable expansion and pressure, so it cannot pass through various special processes, so it is difficult to make a perfect product.

Utility model content

The purpose of the utility model is to provide a watch case, the upper watch case and the bottom cover of the watch case are fixed by fixing clips, which can solve the problems caused by the pressing method.

The watch case in the utility model includes an upper watch case and a bottom cover, wherein the upper watch case and the bottom cover are respectively provided with corresponding grooves, and the gap between the upper watch case and the bottom cover It is sealed by a sealing ring and fixed by at least two fixing clips. The fixing clips are integrally formed of resilient materials and respectively include an arched connection part and two lugs respectively arranged at two ends of the connection part. The lugs are respectively inserted into the grooves of the upper watch case and the bottom cover, for fastening the upper watch case and the bottom cover.

The fixing clip can be made of stainless steel, platinum-iridium alloy or titanium alloy.

There are two fixing clips, and their fixed positions are respectively the positions corresponding to the clocks 6 and 12 on the outer shell and the bottom cover.

The contact portion between the lug and the outer casing and the bottom cover may be a plane.

The material of the sealing ring can be waterproof silica gel or rubber.

The watch case in the utility model fixes the upper watch case and the bottom cover through the fixing clip. Since the fixing clip has resilience, the upper watch case and the bottom cover can be fixed without any tools during use. , and only need to use a small tool to push out the bow-shaped fixing clip when taking it off, which has the advantages of being easy to use and not affecting the appearance of the watch case.

Detailed ways

Specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the watch casing of the present utility model includes an upper watch casing 1 and a bottom cover 2, a waterproof sealing ring 3 is arranged between the upper watch casing 1 and the bottom cover 2, and at the same time at time 6, A bow-shaped fixing clip 4 is respectively provided below the position corresponding to the number at 12 o'clock. However, the number of fixing clips can also be three or more, which are distributed along the periphery of the case body.

As shown in Fig. 2 and Fig. 3, the fixing clip 4 is integrally formed by No. 304 stainless steel material, and No. 303 stainless steel, platinum-iridium alloy, titanium alloy and steel material with resilience can also be selected. The fixing clip 4 includes an arched connecting portion 40 and two lugs 41 at both ends of the connecting portion 40, the lugs 41 are formed by bending the two ends of the connecting portion 40, and are connected with the upper case 1 and the bottom cover 2. The contact part is a plane 42 , that is, the contact between the lug 41 and the upper watch case 1 and the bottom cover 2 is planar contact, which is used to disperse the fixed point pressure when the fixing clip 4 fastens the upper watch case 1 and the bottom cover 2 .

The waterproof sealing ring 3 is made of soft materials such as silica gel or rubber, and is embedded in the groove between the upper watch case 1 and the bottom cover 2 on the inner side of the fixing clip 4 .

As shown in Figure 1, the upper watch case 1 and the bottom cover 2 are provided with grooves 10, 20 corresponding to the lugs 41 of the fixing clip 4, and between the grooves 10, 20 are connected with the upper watch case 1 and the bottom cover 2 The integrally formed protrusions 11 and 21 are respectively inserted into the two lugs 41 of the fixing clip 40 when the upper case 1 and the bottom cover 2 are fastened together. The overlapping thickness of the protrusions 11, 21 is the same as the distance between the two lugs 41, and the overlapping thickness of the protrusions 11, 21 is a positive tolerance, while the distance between the two lugs 41 is a negative tolerance.

Although the present invention has been described with reference to preferred embodiments, the present invention is not limited thereto, and various improvements and modifications can be made to the present invention by those skilled in the art without departing from the spirit and scope of the present invention.
