Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1, for the utility model discloses a but wrist-watch of quick dismantlement bottom, including watchcase 1 and bottom 2, be provided with a button dismantlement subassembly on the lateral wall that watchcase 1 is close to bottom 2, the axis extending direction of button dismantlement subassembly is predetermined acute angle with the joint portion on the bottom 2 and is 45, sets up such acute angle and dismantles bottom 2 more easily for 45 angles.

As shown in fig. 2 and 3, the key detaching assembly includes a key head 3, the key head 3 is disposed in a groove 11 formed in a side wall of the case 1, the key head 3 having a cylindrical structure is matched with the groove 11, and the key head 3 can move left and right in the groove 11; still set up the round hole 12 that runs through 1 lateral wall of watchcase in the recess 11, press the key 3 to be connected with the key-press rod 4 towards one side of round hole 12, and press the key 4 to stretch into watchcase 1 along round hole 12 in, the rod end of key 4 is inconsistent with the joint portion on the bottom 2, the side of joint portion in this embodiment for setting up in 2 edges of bottom, the side can be with the very inseparable conflict of key-press rod 4, according to above-mentioned structure, through removing the key 3 along recess 11, make the key 3 support the key 4, the key 4 supports the joint portion on the bottom 2, make the joint portion on the bottom 2 break away from the inner wall of watchcase 1, thereby dismantle bottom 2 fast.

As shown in fig. 2 and fig. 3, a cavity 31 having a cylindrical structure is provided in the key head 3, one end of the key rod 4 is inserted into the cavity 31, and one end of the key rod 4 inserted into the cavity 31 is provided with an elastic member, the elastic member is a spring 32, the spring 32 is sleeved at one end of the key rod 4, a stopper 41 for extruding the spring 32 is further provided on the outer wall of the key rod 4, one end of the spring 32 is connected to the stopper 41, the other end of the spring 32 is connected to the bottom of the cavity 31, a stopper 33 abutting against the stopper 41 is provided on one side of the cavity 31 facing the groove 11 of the watch case 1, through the abutting of the stopper 33 and the stopper 41, one end of the key rod 4 is blocked by the stopper 33, the cavity 31 of the key head 3 cannot be separated from, and one end of the key rod 4 can only.

When the button head 3 moves along recess 11 in the watchcase 1, slide on the outer wall of button pole 4 along stopper 33 on the button head 3, can play fine guide effect to button pole 4 this moment, make button head 3 slide along recess 11, support top extrusion spring 32 bottom the cavity 31 of button head 3, make spring 32 shrink, spring 32 supports the dog 41 on the button pole 4 again, make button pole 4 remove along the 12 directions of round hole in the recess 11, in order to support the joint portion on the bottom 2, make the joint portion on the bottom 2 break away from the inner wall of watchcase 1, thereby dismantle bottom 2 fast.

As shown in fig. 2 and 3, in this embodiment, the pressing block 42 in an arc-shaped structure is disposed at the end of the key lever 4 abutting against the fastening portion of the bottom cover 2, and the pressing block 42 in the arc shape is matched with the outer wall of the fastening portion of the bottom cover 2, so that the contact area between the pressing block 42 on the key lever 4 and the fastening portion of the bottom cover 2 is increased, the force for spreading the fastening portion of the bottom cover 2 is also increased, and the bottom cover 2 is more easily detached from the watch case 1. Meanwhile, one end of the round hole 12 in the watch case 1, which is close to the clamping part of the bottom cover 2, is provided with a limiting groove 13, the limiting groove 13 is mutually abutted against the extrusion block 42 on the key rod 4, and the key rod 4 can be prevented from being separated out along the round hole 12 through the matching of the limiting groove 13 and the extrusion block 42.

As shown in fig. 4, a sealing rubber ring 5 for sealing and waterproofing is provided on the side wall of the key lever 4, and the sealing rubber ring 5 can prevent external water from entering the inside of the case 1 along the circular hole 12 in the case 1, thereby preventing components such as the movement and the dial in the case 1 from being damaged.

The implementation principle of the embodiment is as follows: when bottom 2 needs to be dismantled, the button head 3 that promotes the watchcase 1 lateral wall removes along recess 11, cavity 31 bottom in the button head 3 supports and pushes extrusion spring 32, make spring 32 shrink, spring 32 supports and pushes up dog 41 on the button pole 4, make button pole 4 move along round hole 12 in the recess 11, the extrusion piece 42 on the button pole 4 supports and pushes up the joint portion on the bottom 2, make the joint portion on the bottom 2 break away from the inner wall of watchcase 1, thereby dismantle bottom 2, after button pole 4 supported bottom 2 and break away from watchcase 1, button head 3 moves along recess 11 direction and resets under the effect that spring 32 elasticity resets, button pole 4 also resets thereupon, extrusion piece 42 on the button pole 4 offsets with spacing groove 13 in the watchcase 1, in order to block button pole 4 and break away from watchcase 1, thereby accomplish the process of dismantling fast of bottom 2.

Example two:

as shown in fig. 5, compared with the first embodiment, the present embodiment is different in that: usually, the strength of women is not as strong as that of men, and only one key disassembling component is arranged on the watch case 1 of the watch, so that the female is not strong enough to push the key disassembling component to disassemble the bottom cover 2 from the watch case 1; therefore, in this embodiment, two key detaching assemblies are disposed on the side of the outer wall of case 1, and may be disposed on the side walls of case 1 in the ten o 'clock direction and the four o' clock direction or on the side walls of case 1 in the two o 'clock direction and the eight o' clock direction in an obliquely corresponding manner, or may be disposed on the side walls of case 1 in the two o 'clock direction and the four o' clock direction or on the side walls of case 1 in the four o 'clock direction and the eight o' clock direction in a corresponding manner.

In this embodiment, as shown in fig. 4, when the bottom cover 2 needs to be detached, the key head 3 on the sidewall of the watch case 1 in the ten o 'clock direction and the four o' clock direction is pushed to move along the groove 11, the bottom of the cavity 31 in the key head 3 abuts against the extrusion spring 32, so that the spring 32 is contracted, the spring 32 abuts against the stopper 41 on the key rod 4, so that the key rod 4 moves along the circular hole 12 in the groove 11, the extrusion block 42 on the key rod 4 abuts against the clamping portion on the bottom cover 2 at the same time, so that the clamping portion on the bottom cover 2 can be easily separated from the inner wall of the watch case 1, thereby detaching the bottom cover 2, after the bottom cover 2 is abutted against the bottom cover 4 and separated from the watch case 1 by the key rod 4, the key head 3 moves and resets along the groove 11 under the elastic resetting action of the spring 32, the key rod 4 also resets, the extrusion block 42 on the key rod 4 abuts against the limiting groove 13, to block the key lever 4 from coming out of the watch case 1, thereby completing the process of quickly disassembling the bottom cover 2 using the two key disassembling assembly.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
