Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to an adjustable fixture. Background Technology

[0002] In the wooden furniture industry, carpenters often encounter situations where they need to join two adjacent wooden components at a predetermined angle during the processing of wooden furniture products. Examples include joining wooden bed frames or the wooden frame inside a sofa base. To assist carpenters in better joining the two wooden components, clamps are usually used to hold them in place. Specifically, during processing, there are cases where the joining angle (i.e., the included angle) between two adjacent wooden components is 90°, such as when joining rectangular frames. Of course, depending on the specific product and user needs, there are also cases where the joining angle between two adjacent wooden components is greater than 90° or less than 90°.

[0003] However, traditional clamps can only adapt to specific splicing angles and cannot adapt well to changes in specific products and user needs. Utility Model Content

[0042] Reference Figures 1 to 7 An adjustable clamp according to an embodiment of the present application includes a base plate 100, a first clamping assembly, a second clamping assembly, and an adjustment structure.

[0043] Specifically, the first clamping component is used to clamp the wooden component a, and the first clamping component is fixedly mounted on the base plate 100. The second clamping component is used to clamp another wooden component a, and the second clamping component is movably mounted on the base plate 100 so that the position of the second clamping component is adjustable. The adjustment structure is used to adjust the position of the second clamping component so that the second clamping component can cooperate with the first clamping component to adapt to different splicing angles. The splicing angle is the included angle between the two wooden components a after splicing.

[0044] When splicing two wooden components a, one wooden component a is clamped and fixed by a first clamping component, and the other wooden component a is clamped and fixed by a second clamping component, and then the woodworker performs the splicing. The second clamping component is movably mounted on the base plate 100, allowing its position to be adjusted. The woodworker can adjust the position of the second clamping component through the adjustment structure, so that the second clamping component can cooperate with the first clamping component to adapt to different splicing angles, thereby better adapting to changes in specific products and user needs.

[0045] Reference Figures 1 to 3 In some embodiments, the first clamping assembly includes a first base 210, a first slider 220, and a first driving structure. The first base 210 is fixedly disposed on the base plate 100, and a first fixing block 230 is fixedly disposed on the first base 210. The first slider 220 is slidably disposed on the first base 210 and is used to cooperate with the first fixing block 230 to clamp the wooden component a. The first driving structure is at least used to drive the first slider 220 closer to the first fixing block 230. In use, the wooden component a to be clamped and fixed is placed between the first slider 220 and the first fixing block 230, and then the first driving structure drives the first slider 220 closer to the first fixing block 230 to achieve clamping and fixing of the wooden component a.

[0046] Specifically, the first fixing block 230 can be integrally formed on the first base 210, or it can be fixed to the first base 210 by screws, which is not limited here.

[0047] Reference Figure 3 In some embodiments, the bottom of the first slider 220 is provided with a first sliding part 221, and the first base 210 is provided with a first sliding groove 211. The first sliding part 221 is slidably disposed in the first sliding groove 211, thereby guiding the sliding process of the first slider 220.

[0048] Specifically, the first sliding part 221 is T-shaped, and the cross-section of the first sliding groove 211 is T-shaped, which can restrict the first sliding part 221 from disengaging from the first sliding groove 211, which is beneficial to improving the stability and reliability of the first slider 220 during operation.

[0049] It should be noted that in some other embodiments, the first sliding part 221 may also be disposed on the first base 210, and correspondingly, the first sliding groove 211 is disposed on the bottom of the first slider 220.

[0050] Reference Figures 1 to 4In some embodiments, the first driving structure includes a first screw 240, and a second fixing block 250 is fixedly disposed on the first base 210 corresponding to the first screw 240. The second fixing block 250 is located on the side of the first slider 220 facing away from the first fixing block 230. The second fixing block 250 is provided with a first mounting through hole 251 facing the first slider 220. The first screw 240 passes through the first mounting through hole 251. The end of the first screw 240 close to the first slider 220 acts on the first slider 220. The end of the first screw 240 away from the first slider 220 is provided with a first handle 260. At least one end of the first mounting through hole 251 is fixedly provided with a first nut 270 threadedly connected to the first screw 240. In use, force can be applied to the first handle 260 to drive the first screw 240 to rotate, thereby bringing the first screw 240 closer to or away from the first fixed block 230. When the first screw 240 is close to the first fixed block 230, it can act on the first slider 220 and drive the first slider 220 closer to the first fixed block 230.

[0051] It should be noted that in some other embodiments, the first mounting through hole 251 is a threaded hole, and the first screw 240 is threadedly connected to the first mounting through hole 251. In this case, it is not necessary to set the first nut 270 mentioned above.

[0052] Reference Figure 2 and Figure 3 In some embodiments, the end of the first screw 240 near the first slider 220 is rotatably connected to the first slider 220. Specifically, the first slider 220 is provided with a first insertion groove (not shown in the figure) corresponding to the first screw 240. The end of the first screw 240 near the first slider 220 is inserted into the first insertion groove. The end of the first screw 240 near the first slider 220 is provided with a first limiting part 241 for preventing detachment. A first baffle 300 is fixedly provided at the opening of the first insertion groove corresponding to the first limiting part 241. In this case, the first screw 240 can not only drive the first slider 220 closer to the first fixing block 230, but also drive the first slider 220 away from the first fixing block 230.

[0053] Specifically, the first baffle 300 can be welded to the first slider 220 or fixed to the first slider 220 by screws, which is not limited here.

[0054] It should be noted that in some other embodiments, the end of the first screw 240 near the first slider 220 may only abut against the first slider 220. In this case, the first screw 240 can only drive the first slider 220 to approach the first fixing block 230. When it is necessary to release the clamping and fixing of the wooden part a, force is applied to the first handle 260 to drive the first screw 240 to rotate, thereby moving the first screw 240 away from the first fixing block 230. This provides space for the first slider 220 to move away from the first fixing block 230, thereby releasing the clamping and fixing of the wooden part a.

[0055] It should be noted that in some other embodiments, the first drive structure may also be an elbow clamp.

[0056] In some embodiments, the first base 210 is detachably mounted on the base plate 100, allowing the first clamping assembly to be removed from the base plate 100 to achieve the purpose of breaking down the whole into parts for easy transportation and carrying, thereby facilitating on-site carpentry services.

[0057] Specifically, the first base 210 is fixed to the base plate 100 by screws. Of course, the first base 210 can also be fixed to the base plate 100 by a snap-fit ​​structure, which is not limited here.

[0058] Reference Figure 1 , Figure 2 and Figure 5 In some embodiments, the second clamping assembly includes a second base 410, a second slider 420, and a second driving structure. The second base 410 is movably disposed on the base plate 100, and a third fixing block 430 is fixedly disposed on the second base 410. The second slider 420 is slidably disposed on the second base 410 and is used to cooperate with the third fixing block 430 to clamp the wooden component a. The second driving structure is at least used to drive the second slider 420 closer to the third fixing block 430, and the adjusting structure is used to adjust the position of the second base 410. In use, the wooden component a to be clamped and fixed is placed between the second slider 420 and the third fixing block 430, and then the second driving structure drives the second slider 420 closer to the third fixing block 430 to achieve clamping and fixing of the wooden component a.

[0059] Specifically, the third fixing block 430 can be integrally formed on the second base 410, or it can be fixed to the second base 410 by screws, which is not limited here.

[0060] Reference Figure 5 In some embodiments, the bottom of the second slider 420 is provided with a second sliding part 421, and the second base 410 is provided with a second sliding groove 411. The second sliding part 421 is slidably disposed in the second sliding groove 411, thereby guiding the sliding process of the second slider 420.

[0061] Specifically, the second sliding part 421 is T-shaped, and the cross-section of the second sliding groove 411 is T-shaped, which can restrict the second sliding part 421 from disengaging from the second sliding groove 411, thereby improving the stability and reliability of the second slider 420 during operation.

[0062] It should be noted that in some other embodiments, the second sliding part 421 may also be disposed on the second base 410, and correspondingly, the second sliding groove 411 is disposed on the bottom of the second slider 420.

The fourth fixing block 450 is located on the side of the second slider 420 facing away from the third fixing block 430. The fourth fixing block 450 is provided with a second mounting through hole 451 facing the second slider 420. The second screw 440 passes through the second mounting through hole 451. The end of the second screw 440 near the second slider 420 acts on the second slider 420. The end of the second screw 440 away from the second slider 420 is provided with a second handle 460. At least one end of the second mounting through hole 451 is fixedly provided with a second nut 470 threadedly connected to the second screw 440. In use, force can be applied to the second handle 460 to drive the second screw 440 to rotate, thereby bringing the second screw 440 closer to or away from the third fixed block 430. When the second screw 440 is close to the third fixed block 430, it can act on the second slider 420 and drive the second slider 420 closer to the third fixed block 430.

[0064] It should be noted that in some other embodiments, the second mounting through hole 451 is a threaded hole, and the second screw 440 is threadedly connected to the second mounting through hole 451. In this case, it is not necessary to set the second nut 470 mentioned above.

[0065] Reference Figure 5In some embodiments, the end of the second screw 440 near the second slider 420 is rotatably connected to the second slider 420. Specifically, the second slider 420 is provided with a second insertion groove (not shown in the figure) corresponding to the second screw 440. The end of the second screw 440 near the second slider 420 is inserted into the second insertion groove. The end of the second screw 440 near the second slider 420 is provided with a second limiting part 441 for preventing detachment. A second baffle 500 is fixedly provided at the opening of the second insertion groove corresponding to the second limiting part 441. At this time, the second screw 440 can not only drive the second slider 420 to approach the third fixing block 430, but also drive the second slider 420 away from the third fixing block 430.

[0066] Specifically, the second baffle 500 can be welded to the second slider 420 or fixed to the second slider 420 with screws, which is not limited here.

[0067] It should be noted that in some other embodiments, the end of the second screw 440 near the second slider 420 may only abut against the second slider 420. In this case, the second screw 440 can only drive the second slider 420 to approach the third fixing block 430. When it is necessary to release the clamping and fixing of the wooden part a, force is applied to the second handle 460 to drive the second screw 440 to rotate, thereby moving the second screw 440 away from the third fixing block 430. This provides space for the second slider 420 to move away from the third fixing block 430, thereby releasing the clamping and fixing of the wooden part a.

[0068] It should be noted that in some other embodiments, the second drive structure may also be an elbow clamp.

[0069] Reference Figure 1 , Figure 2 , Figure 5 and Figure 7In some embodiments, the adjustment structure includes an arc-shaped through hole 110 on the base plate 100, a first connecting part 412 on one side of the second base 410, a second connecting part 413 on the other side of the second base 410, a first screw 600 passing through the first connecting part 412 and the first screw 600 passing through the arc-shaped through hole 110, a third nut 700 for locking the first connecting part 412 being threaded onto the first screw 600, a second screw 800 passing through the second connecting part 413, and a fourth nut 900 fixedly provided on the base plate 100 at the center of the arc-shaped through hole 110, the second screw 800 being threaded onto the fourth nut 900. When the splicing angle needs to be changed, loosen the first screw 600 and the second screw 800, then drive the second screw 800 to slide along the arc-shaped through hole 110, thereby changing the position of the second base 410, and thus changing the position of the second clamping assembly. After the second base 410 moves to the desired position, tighten the first screw 600 and the second screw 800 again, thereby fixing the position of the second base 410, and thus fixing the position of the second clamping assembly. In addition, the second clamping assembly with the above-described adjustment structure can be detached from the base plate 100 to achieve the purpose of disassembling the whole into parts, so as to facilitate transportation and carrying, thereby facilitating woodworking on-site services.

[0070] It should be noted that in some other embodiments, a threaded connection hole is provided on the base plate 100 at the center of the arc-shaped through hole 110, and the second screw 800 is threaded into the threaded connection hole. In this case, there is no need to provide the aforementioned fourth nut 900, and the second clamping assembly can also be removed from the base plate 100.

[0071] In the above structure, the first screw 600, in conjunction with the third nut 700, can lock the first connecting part 412, and the second screw 800, in conjunction with the fourth nut 900 or the threaded connecting hole, can lock the second connecting part 413. This helps to improve the stability and reliability of the second clamping assembly during operation.

[0072] Specifically, the arc-shaped through hole 110 is a stepped hole so that the fourth nut 900 can be accommodated in the arc-shaped through hole 110, thereby improving the flatness of the bottom of the base plate 100.

[0073] It should be noted that in some other embodiments, the second screw 800 described above can be replaced by a plug-in part provided at the bottom of the second connecting part 413. Correspondingly, a plug-in hole is provided on the base plate 100 at the center of the arc-shaped through hole 110, and the plug-in part is rotatably inserted into the plug-in hole. In this case, it is not necessary to provide the fourth nut 900 or the threaded connection hole described above.

[0074] In some embodiments, the base plate 100 is provided with a scale corresponding to the arc-shaped through hole 110 for indicating the splicing angle, so that the carpenter can adjust the splicing angle.

[0075] Reference Figure 1 and Figure 2 In some embodiments, a notch 120 for positioning the base plate 100 is provided at its edge. During use, the notch 120 can be fitted into a structure on the processing site to position the base plate 100, thus preventing it from shifting during operation. Specifically, the notch 120 is rectangular, meaning the angle between adjacent inner walls of the notch 120 is a right angle, allowing the base plate 100 to be positioned using the edges of a wall or other structures.
