Description

Technical Field

[0001] The utility model belongs to the technical field of watch tool processing, in particular to a watch case clamp. Background Art

[0002] Traditional watch case clamping only has two forms: internal support and external clamping. Both are implemented on the case body, and all the expansion and clamping forces are applied to the case body. However, the case is mainly used to decorate the watch body, and its own structure is weaker than the watch body. When the clamping force is applied to the case body, the pressure generated by the tool clamping can easily cause the case to deform. Therefore, the existing case clamps still have room for improvement. Utility Model Content

[0003] The utility model aims to improve the problem that the existing clamp directly clamps the watch case body, which causes the watch case to be deformed, and provides a watch case clamp.

[0004] The technical solutions to achieve the above objectives include the following:

[0005] A watch case clamp comprises a first support member and a second support member, wherein the first support member is mounted on the second support member and forms a clamping position with the second support member, wherein the clamping position is used to accommodate the watch case; the watch case is sleeved outside the first support member, and in a first direction, the first support member is used to abut against the first end of the watch case, and the second support member is used to abut against the second end of the watch case.

[0006] In one embodiment, the first support member has at least one limit block, and in the second direction, the limit block is used to abut against at least a portion of the watch case; the first direction intersects with the second direction.

[0007] In one embodiment, the watch case has a watch ear, a slot is formed in the watch ear, the limit block cooperates with the slot, and the limit block has a contact surface, and the contact surface is used to contact with the inner wall of the slot.

[0008] In one embodiment, there are four limit blocks, two of which are located on one side of the first support member, and the other two are located on the other side of the first support member; the number of the limit blocks corresponds to the number of the lugs.

[0009] In one embodiment, the first support member has a first internal thread and a first external thread, the watch case has a second internal thread, and the first external thread is threadedly matched with the second internal thread; the second support member has a second external thread, and the first internal thread is threadedly matched with the second external thread.

[0010] In one embodiment, the watch case clamp further has a damping rubber ring, the second support member has a mounting groove, the damping rubber ring is sleeved on the outside of the second support member and installed in the mounting groove, and the damping rubber ring is located at the lower end of the second external thread.

[0011] In one embodiment, the damping rubber ring is extended along the circumference of the second support member, the cross section of the damping rubber ring is circular, and the outer surface of the damping rubber ring is used to contact the wall surfaces of the first support member and the second support member.

[0012] In one embodiment, the bottom of the first support member has a first support surface, the top of the second support member has a second support surface, the first support surface is in contact with the second support surface; and the width of the first support surface is smaller than the width of the second support surface.

[0013] In one embodiment, the outer wall of the first support member has an L-shaped groove, and the inner wall of the watch case fits with the outer wall of the L-shaped groove.

[0014] In one embodiment, the bottom of the second support member has at least two clamping grooves, and the two clamping grooves are distributed along the circumference of the second support member.

[0015] The technical solution provided by the utility model has the following advantages and effects:

[0016] A first support member is installed on a second support member, and a clamping position for accommodating a watch case is formed between the first support member and the second support member. The watch case is sleeved on the outside of the first support member. The first support member is used to support the watch case. In a first direction, the first support member and the second support member respectively abut against two ends of the watch case, thereby limiting the position of the watch case on the clamping position. The watch case is supported by the first support member, and the watch case is sleeved on the outside of the first support member, thereby increasing the contact area between the watch case and the first support member, avoiding the use of internal support and external clamping to fix the watch case, reducing the supporting force and clamping force of the watch case, reducing the local force on the outer surface of the watch case, and improving the problem of the existing clamp directly clamping the watch case body to cause the watch case to deform.

[0030] like Figures 1 to 4As shown, a watch case 3 clamp 100 includes a first support member 1 and a second support member 2, wherein the first support member 1 is installed on the second support member 2 and forms a clamping position 50 with the second support member 2, and the clamping position 50 is used to accommodate the watch case 3; the watch case 3 is sleeved on the outside of the first support member 1, and in a first direction, the first support member 1 is used to abut against the first end of the watch case 3, and the second support member 2 is used to abut against the second end of the watch case 3. A first support member 1 is installed on a second support member 2, and a clamping position 50 for accommodating a watch case 3 is formed between the first support member 2 and the second support member 2. The watch case 3 is sleeved on the outside of the first support member 1. The first support member 1 is used to support the watch case 3. In a first direction, the first support member 1 and the second support member 2 respectively abut against two ends of the watch case 3, thereby limiting the position of the watch case 3 on the clamping position 50. The watch case 3 is supported by the first support member 1, and the watch case 3 is sleeved on the outside of the first support member 1, so as to increase the contact area between the watch case 3 and the first support member 1, avoid fixing the watch case 3 by means of internal support and external clamping, reduce the supporting force and clamping force of the watch case 3, reduce the local force on the outer surface of the watch case 3, and improve the problem of deformation of the watch case 3 caused by the existing clamp 100 directly clamping the watch case 3 body.

[0031] like Figure 1 and Figure 2 As shown, the first support member 1 has at least one stopper 11, and in the second direction, the stopper 11 is used to abut against at least part of the watch case 3; the first direction intersects with the second direction. In this embodiment, by using the stopper 11 to abut against at least part of the watch case 3 in the second direction, the position of the watch case 3 on the first support member 1 is further limited; moreover, the first direction intersects with the second direction, so that the watch case 3 is limited in two different directions, and it itself is sleeved outside the first support member 1, thereby further improving the stability of the watch case 3 during processing. In this embodiment, the first direction is the height direction of the watch case 3, and the second direction is the circumferential direction of the watch case 3.

[0032] like Figure 1 , Figure 2 as well as Figure 5 As shown, the watch case 3 has a lug 31, a slot 311 is formed in the lug 31, the limit block 11 cooperates with the slot 311, and the limit block 11 has a contact surface 111, and the contact surface 111 is used to contact with the inner wall of the slot 311. In this embodiment, the limit block 11 is used to cooperate with the slot 311 of the watch case 3. When the watch case 3 is sleeved on the first support member 1, the limit block 11 cooperates with the slot 311, and the contact surface 111 of the limit block 11 contacts with the inner wall of the slot 311, further improving the stability of the watch case 3 on the first support member 1.

[0033] like Figure 1 and Figure 2As shown, there are four limit blocks 11, two of which are located on one side of the first support member 1, and the other two limit blocks 11 are located on the other side of the first support member 1; the number of the limit blocks 11 corresponds to the number of the lugs 31. In this embodiment, four limit blocks 11 are used, which correspond to the lugs 31 of the watch case 3 respectively, and the four limit blocks 11 are distributed on both sides of the first support member 1, so as to further improve the stability of the watch case 3 on the first support member 1.

[0034] like Figure 1 , Figure 2 as well as Figure 5 As shown, the first support member 1 has a first internal thread 12 and a first external thread 13, the watch case 3 has a second internal thread 32, and the first external thread 13 is threadedly matched with the second internal thread 32; the second support member 2 has a second external thread 21, and the first internal thread 12 is threadedly matched with the second external thread 21. In this embodiment, the first external thread 13 of the first support member 1 is threadedly connected with the second internal thread 32 of the watch case 3, which improves the convenience of installing the watch case 3 on the first support member 1. Moreover, the first internal thread 12 of the first support member 1 is threadedly connected with the second external thread 21 of the second support member 2, which also facilitates the assembly of the first support member 1 and the second support member 2, and improves the connection stability between the first support member 1 and the second support member 2.

[0035] like Figure 2 and Figure 3 As shown, the case 3 fixture 100 also has a damping rubber ring 4, and the second support member 2 has a mounting groove 24. The damping rubber ring 4 is sleeved on the outside of the second support member 2 and installed in the mounting groove 24, and the damping rubber ring 4 is located at the lower end of the second external thread 21. In this embodiment, the damping rubber ring 4 is sleeved on the outside of the second support member 2. When the first support member 1 is installed on the second support member 2, the damping rubber ring 4 is used to be located between the first support member 1 and the second support member 2. When the first support member 1 and the second support member 2 are tightened, the damping rubber ring 4 is deformed and has a damping effect, preventing the connection between the first support member 1 and the second support member 2 from loosening, and improving the connection stability between the first support member 1 and the second support member 2.

[0036] like Figure 2 As shown, the damping rubber ring 4 is extended along the circumference of the second support member 2, the cross-section of the damping rubber ring 4 is circular, and the outer surface of the damping rubber ring 4 is used to contact the wall surfaces of the first support member 1 and the second support member 2; when the first support member 1 and the second support member 2 are threadedly matched, as the first support member 1 continuously squeezes the damping rubber ring 4, the outer surface of the damping rubber ring 4 rolls with the wall surfaces of the first support member 1 and the second support member 2, and the damping rubber ring 4 is deformed, further preventing the connection between the first support member 1 and the second support member 2 from loosening.

[0037] like Figure 2 and Figure 3 As shown, the bottom of the first support member 1 has a first support surface 15, and the top of the second support member 2 has a second support surface 22, and the first support surface 15 is in contact with the second support surface 22; and the width of the first support surface 15 is smaller than the width of the second support surface 22, so that the first support surface 15 and the outer side of the second support surface 22 form a clamping position 50, wherein the bottom of the first support surface 15 is at least partially bent, and the first support surface 15 and the second support surface 22 are respectively used to abut against the two ends of the case 3, thereby further improving the stability of the case 3 at the clamping position 50.

[0038] like Figure 3 As shown, the outer wall of the first support member 1 has an L-shaped groove 14, and the inner wall of the watch case 3 fits with the outer wall of the L-shaped groove 14. The L-shaped groove 14 is used to fit with the inner wall of the watch case 3, increase the contact area between the watch case 3 and the first support member 1, and further improve the stability of the watch case 3 on the first support member 1. In this embodiment, the L-shaped groove 14 is set according to the shape of the inner wall of the watch case 3.

[0039] like Figure 2 and Figure 3 As shown, the bottom of the second support member 2 has at least two clamping grooves 23, and the two clamping grooves 23 are distributed along the circumference of the second support member 2. The clamping grooves 23 are used to fix with the chuck, improve the stability of the first support member 1 on the chuck, and make the chuck drive the second support member 2 to rotate, so as to facilitate the clamp 100 to process the watch case 3 when rotating.

[0040] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.
