The embodiment of the application discloses convenient to detach formula wrist-watch watchcase.

Referring to fig. 1 to 3, the watch case of the easy-to-detach type includes a case 1 and a bottom cover 2. The back of the shell 1 is provided with a first opening 11 for the movement to enter and exit the shell 1, and two parallel sliding grooves 12 are correspondingly arranged on two sides of the shell 1 close to the first opening 11 one by one; two parallel edges of the bottom cover 2 are matched with the two sliding grooves 12. In this embodiment, the sliding groove 12 is generally dovetail-shaped, so as to facilitate processing and to have a good appearance. In order to facilitate the drawing of the bottom cover 2 in the slide groove 12, one end of the slide groove 12 penetrates the housing 1 to form an access opening 111 for the bottom cover 2 to be inserted. Thus, the two edges of the bottom cover 2 can pass through the two entrances and exits 111 in a one-to-one correspondence, and can slide in the two slide grooves 12 in a one-to-one correspondence. The first opening 11 is opened when the bottom cover 2 exits the slide groove 12, and the first opening 11 is closed when the bottom cover 2 enters the slide groove 12. This easy detach formula watch case still includes anti-skidding subassembly 3. Correspondingly, the housing 1 is provided with an accommodating groove 14 near the entrance 111, and the bottom cover 2 is provided with a limiting groove 21 matched with the accommodating groove 14. The anti-slip assembly 3 comprises an elastic member 31 and a blocking member 32 connected to the elastic member 31, the elastic member 31 is disposed in the receiving groove 14, at least a portion of the blocking member 32 is disposed in the receiving groove 14, and an end of the blocking member 32 away from the elastic member 31 can be inserted into the limiting groove 21.

Referring to fig. 2, two parallel edges of the bottom cover 2 pass through the opening 111, the surface of the bottom cover 2 presses the blocking member 32, the blocking member 32 presses the elastic member 31, the blocking member 32 completely enters the receiving groove 14, and the bottom cover 2 can slide in the sliding groove 12; accordingly, the bottom cover 2 closes or opens the first opening 11; after the bottom cover 2 closes the first opening 11, the position of the limiting groove 21 corresponds to the position of the receiving groove 14, and the elastic force of the elastic member 31 causes one end of the blocking member 32 away from the elastic member 31 to be embedded into the limiting groove 21 of the bottom cover 2, so that the bottom cover 2 and the bottom cover 2 do not move relative to each other, i.e. the bottom cover 2 tightly closes the first opening 11. When disassembly is required, a thin sheet tool is inserted into the gap between the bottom cover 2 and the housing 1 to return the stopper 32 into the receiving groove 14, and the bottom cover 2 is pulled by hand to easily remove the bottom cover 2, thereby opening the first opening 11. The bottom cover 2 is disassembled without screwing screws or prying the bottom cover 2 with great force, so that the watch is very favorable for replacing batteries and maintaining.

Referring to fig. 4 to 6, in order to prevent the anti-slip member 3 from being completely ejected when the bottom cover 2 is detached from the housing 1, the cross-sectional area of the notch of the receiving groove 14 is gradually reduced in a direction toward the first opening 11, that is, the notch is closed. The closing is performed after the elastic member 31 and the blocking member 32 are both placed in the accommodating groove, and specifically, the notch of the accommodating groove 14 can be conveniently extruded or punched by means of a punch workpiece, and the notch is trimmed to make the surrounding housing 1 of the accommodating groove 14 be a plane.

Referring to fig. 5, since the notch of receiving groove 14 is large inside and small outside, blocking member 32 will not slip out of receiving groove 14 after bottom cover 2 is pulled out from slide groove 12, and thus, blocking member 32 is prevented from being lost when the watch case is detached. Because friction is generated between the blocking member 32 and the bottom cover 2 when the bottom cover 2 is assembled and disassembled, in order to reduce the abrasion between the blocking member 32 and the bottom cover 2, one end of the blocking member 32, which is far away from the elastic member 31, is a spherical surface, and correspondingly, the groove surface of the limiting groove 21 is also a spherical surface.

Referring to fig. 5, when the blocking member 32 is ejected out of the receiving groove 14 by the elastic member 31, in order to reduce the skew of the blocking member 32, the receiving groove 14 and the blocking member 32 are both cylindrical, one end of the blocking member 32 connected to the elastic member 31 is a flat surface, and the elastic member 31 is a wave spring. The wave spring and blocking piece 32 are in plane compression and contact, the contact area is large, the force bearing area of blocking piece 32 is large, the force bearing is uniform, and blocking piece 32 can linearly enter and exit accommodating groove 14.

Referring to fig. 2, the watch case further comprises a sealing ring 4 in order to enable sealing between the bottom cover 2 and the case 1 when the bottom cover 2 is closed on the bottom of the case 1. Correspondingly, the bottom cover 2 and the housing 1 are each provided with a sealing groove 13 adapted to the sealing ring 4. During assembly, the sealing ring 4 is placed in the sealing groove 13 of the shell 1, the bottom of the shell 1 is covered by drawing the bottom cover 2, and at the moment, the sealing ring 4 is clamped between the bottom cover 2 and the shell 1, so that water and steam can be reduced to enter the shell 1 and damage the movement.

Referring to fig. 7 to 8, in order to facilitate the user to pull and draw the bottom cover 2, the bottom cover 2 is provided with a recess 22, and the recess 22 is exposed after the bottom cover 2 closes the first opening 11. When the user pulls the bottom cover 2 by hand, the user can hold the concave hole 22 by fingers and pull the bottom cover 2, and the concave hole 22 provides a good force application part for pulling the bottom cover 2 out. Specifically, the concave hole 22 is close to the inlet/outlet 111. Therefore, the fingers clamp the end of the bottom cover 2 and then pull the bottom cover 2, which accords with the human body principle.

Referring to fig. 8, when the bottom cover 2 closes the first opening 11, abrasion occurs in order to reduce collision of the end of the bottom cover 2 with the inside of the case 1. An escape space 23 is provided at an end of the bottom cover 2 away from the entrance 111 after the bottom cover 2 closes the first opening 11.
