Description

Technical Field

[0001] The present invention relates to the field of accessories for woodworking cutting workbenches, and particularly to a quick-release mounting base. Background Art

[0002] A miter saw stand is a device specifically designed to support and fix a miter saw (also known as a miter table saw or push table saw). It enables the miter saw to be used flexibly without a fixed workbench, and is particularly suitable for woodworkers, construction workers or DIY enthusiasts to move and use at different locations or for different projects.

[0003] In the patent with the patent number CN214490930U and the patent name of snap-type lead screw base, a lead screw base for clamping on the tabletop of a bracket is disclosed. This lead screw base solves the bearing problem of a heavy-duty miter saw, makes the lead screw base more stable during cutting work, and reduces the phenomenon of vibration of the miter saw stand. However, for a light-duty miter saw and when cutting relatively soft materials, this lead screw base is too bulky and lacks flexibility, resulting in inconvenient use. Summary of the Invention

[0004] Aiming at the defects existing in the prior art, the technical problem to be solved by the present utility model is that the lead screw base is too heavy and lacks portability. To solve the above problems, the present utility model provides a quick-release mounting base, which uses an elastic handle to clamp the miter saw stand. When the miter saw needs to be moved, directly pinch the handle and move it together with the miter saw, solving the problem of poor portability of the mounting base.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A quick-release mounting base includes a mounting frame, a clamping handle, a clamping block and an elastic member. The mounting frame is a rectangular pipe body with an open bottom surface. The mounting frame is provided with a mounting groove at the top and a component opening in the middle. The clamping block is installed at one end of the component opening, the clamping handle is rotatably installed at the other end of the component opening, the elastic member is installed between the clamping handle and the mounting frame, and a clamping space is formed between the clamping block and the clamping handle.

[0007] With such a structure, the handle can rotate elastically on the mounting frame. After the clamping block buckles the miter saw stand, release the handle, and under the action of the elastic member, it presses against the miter saw stand downward to complete the fixation. When the miter saw needs to be moved, pinch the handle to disengage the clamping state, and it can move back and forth on the miter saw stand. Such a quick-release mounting base uses an elastic handle to clamp the miter saw stand. When the miter saw needs to be moved, directly pinch the handle and move it together with the miter saw, solving the problem of poor portability of the mounting base.

[0008] Preferably, a supporting portion is provided on the top of the clamping handle, and the supporting portion contacts the top of the mounting frame. A limit is set for rebound. If there is no limit of the supporting portion, the clamping handle will continue to rotate under the action of the elastic member until the elastic member falls off or the clamping handle falls off, which will increase the difficulty of use and reduce work efficiency.

[0009] Furthermore, the clamping handle includes limiting protrusions, which are arranged on both sides of the clamping handle. The limiting protrusions prevent the clamping handle from rotating excessively upward, which causes the elastic member to be over-compressed, plastically deformed, and then fail.

[0010] Preferably, the elastic member is a cylindrical spring, which is a variable diameter spring with a large diameter in the middle and small diameters at both ends. Since the compression line is in an arc shape during the process of pinching the clamping handle, conventional cylindrical springs are more likely to undergo plastic deformation after multiple compressions, resulting in a weakening of the forward force of the clamping handle, resulting in a loose clamp. The variable diameter spring has a large deformation capacity due to its special structure, which allows it to produce a large compression displacement when subjected to a load, making the clamping handle more durable when pinched and compressed.

[0011] Preferably, the elastic member is a torsion spring, which resists the torque of rotation, so that the clamping handle has the characteristics of good hand feeling and long service life during the process of pinching and rebounding.

[0012] Preferably, a rotatable fixed half ring is provided on the clamping block, and the end of the fixed half ring can be detachably fixed on the mounting frame.

[0013] On the one hand, the function of timely adjusting the position of the cutting tool during operation is maintained, and on the other hand, the problem of the cutting tool falling during movement is solved, further optimizing the potential problems of this quick-release mounting bracket. The clamping handle, clamping block and fixed half ring are all made of high-strength resin materials. The high-strength resin can prevent the clamping stand from being scratched while ensuring that it does not break. When the end of the fixed half ring is fixed on the metal mounting bracket, the fixed half ring can be kept from falling off. Such a quick-release mounting seat uses the clamping block and the fixed half ring to embrace the bracket on the work surface, which solves the problem of the cutting tool falling due to the need to move its position during operation, and improves the safety of the mounting bracket.

[0014] Preferably, the end of the fixed half ring is provided with a top block that can be pressed inward, and the mounting frame is provided with a positioning hole, and the top block is detachably inserted in the positioning hole. The top block is inserted in the positioning hole of the mounting frame, which can effectively prevent the fixed half ring from detaching from the mounting frame and reduce the difficulty of disassembly.

[0015] Further, an elastic pressing plate is provided at the end of the fixed semi-ring. The side and rear of the elastic pressing plate are disconnected from the fixed semi-ring, so that the elastic pressing plate can be pressed inward and rebound. The top block is arranged at the end of the elastic pressing plate. The design of the elastic pressing plate reduces the manufacturing cost of the rebounding mechanism and prolongs the service life of the mechanism at the same time.

[0016] Preferably, it further includes a fixing bolt, and the fixing bolt is installed in the installation groove. The fixing bolt is a full-thread bolt. The fixing bolt is used to connect and fix the cutting tool, and the full-thread fixing bolt further adapts to different cutting tools.

[0017] Further, a square protrusion is provided at the bottom of the fixing bolt. When the fixing bolt is lifted, the square protrusion is inserted into the installation groove to make the fixing bolt non-rotatable. Such a design does not require a wrench to be used for fixing below, improving the installation efficiency.

[0018] Preferably, it further includes a connecting seat, and the connecting seat is fixed at both ends of the bottom of the mounting frame. The connecting seat connects and fixes the bottom opening of the mounting frame, improving the strength of the mounting frame.

[0019] In summary, for such a quick-release mounting seat, the elastic handle is used to clamp the miter saw bracket. When the miter saw needs to be moved, the handle is directly pinched and moved together with the miter saw, solving the problem of poor portability of the mounting seat.

Detailed implementation mode

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] A quick-release mounting seat includes a mounting bracket 1, a clamping handle 2, a clamping block 3 and an elastic member 4. The mounting bracket 1 is a rectangular pipe body with an open bottom surface. The mounting bracket 1 is provided with a mounting groove 11 at the top and a component opening 12 in the middle. The clamping block 3 is installed at one end of the component opening 12, the clamping handle 2 is rotatably installed at the other end of the component opening 12, the elastic member 4 is installed between the clamping handle 2 and the mounting bracket 1, and a clamping space 0 is formed between the clamping block 3 and the clamping handle 2.

[0031] As Figure 1 As shown, as the first embodiment of this implementation mode, adopting such a structure, the handle 2 can rotate elastically on the mounting bracket 1. After the clamping block 3 buckles the miter saw bracket, release the handle 2, and under the action of the elastic member 4, it abuts against the miter saw bracket downward to complete the fixation. When the miter saw needs to be moved, pinch the handle 2 to disengage the clamping state, and it can move back and forth on the miter saw bracket. Such a quick-release mounting seat uses the elastic handle 2 to clamp the miter saw bracket. When the miter saw needs to be moved, directly pinch the handle 2 and move it together with the miter saw, solving the problem of poor portability of the mounting seat.

[0032] Preferably, the top of the clamping handle 2 is provided with an abutting part 21, and the abutting part 21 contacts the top of the mounting bracket 1. A limit is set for the rebound. Without the limit of the abutting part 21, the clamping handle 2 will keep rotating under the action of the elastic member 4 until the elastic member 4 falls off or the clamping handle 2 falls off. In this case, it will increase the difficulty of use and reduce the work efficiency.

[0033] Furthermore, the clamping handle 2 includes a limiting protrusion 22, and the limiting protrusion 22 is arranged on both sides of the clamping handle 2. The limiting protrusion 22 prevents the clamping handle 2 from rotating upward excessively, resulting in excessive compression of the elastic member 4 and plastic deformation and failure.

[0034] Specifically, the elastic member 4 is a cylindrical spring 41, and the cylindrical spring 41 is a variable diameter spring with a large diameter in the middle and small diameters at both ends. Since the compression line is in an arc shape during the process of pinching the clamping handle 2, the conventional cylindrical spring 41 is more likely to undergo plastic deformation after multiple compressions, resulting in a weakening of the force pushing forward at the clamping handle 2, resulting in a loose clamping situation. The variable diameter spring has a large deformation capacity due to its special structure, which allows it to produce a large compression displacement when subjected to a load, making the clamping handle 2 more durable when pinched and compressed.

[0035] Specifically, the elastic member 4 is a torsion spring 42. The torsion spring 42 resists the rotational torque, so that the clamping handle 2 has the characteristics of good hand feeling and long service life during the process of pinching and rebounding.

[0036] like Figure 4 As shown, as a second example of the present embodiment, preferably, a rotatable fixed half ring 5 is provided on the clamping block 3, and the end of the fixed half ring 5 can be detachably fixed on the mounting frame 1.

[0037] On the one hand, the function of timely adjusting the position of the cutting tool during operation is maintained, and on the other hand, the problem of the cutting tool falling during movement is solved, further optimizing the potential problems of this quick-release mounting frame 1. The clamping handle 2, the clamping block 3 and the fixed half ring 5 are all made of high-strength resin materials. The high-strength resin can prevent the clamping frame from being scratched while ensuring that it does not break. When the end of the fixed half ring 5 is fixed on the metal mounting frame 1, the fixed half ring 5 can be kept from falling off. Such a quick-release mounting seat uses the clamping block 3 and the fixed half ring 5 to fit on the bracket of the work surface, which solves the problem of the cutting tool falling due to the need to move its position during operation, and improves the safety of the mounting frame 1.

[0038] Furthermore, the end of the fixed half ring 5 is provided with a top block 51 that can be pressed inward, and the mounting frame 1 is provided with a positioning hole 13, and the top block 51 can be removably inserted in the positioning hole 13. The top block 51 is inserted in the positioning hole 13 of the mounting frame 1, which can effectively prevent the fixed half ring 5 from being separated from the mounting frame 1 and reduce the difficulty of disassembly.

[0039] Specifically, a spring plate 52 is provided at the end of the fixed half ring 5, and the side and rear of the spring plate 52 are disconnected from the fixed half ring 5, so that the spring plate 52 can be pressed inward and rebound, and the top block 51 is provided at the end of the spring plate 52. The design of the spring plate 52 reduces the manufacturing cost of the rebound mechanism and also prolongs the service life of the mechanism.

[0040] Preferably, it further comprises a fixing bolt 6, which is installed in the installation groove 11 and is a fully threaded bolt. The fixing bolt 6 is used to connect and fix the cutting tool, and the fully threaded fixing bolt 6 is further adapted to different cutting tools.

[0041] Furthermore, a square protrusion 61 is provided at the bottom of the fixing bolt 6. When the fixing bolt 6 is lifted, the square protrusion 61 is inserted into the installation groove 11 to make the fixing bolt 6 non-rotatable. Such a design does not require the use of a wrench to fix it below, improving the installation efficiency.

[0042] Preferably, it further includes a connecting seat 7, and the connecting seats 7 are fixed at both ends of the bottom of the mounting bracket 1. The connecting seat 7 connects and fixes the bottom opening of the mounting bracket 1, improving the strength of the mounting bracket 1.

[0043] In summary, such a quick-release mounting seat uses the clamping block and the fixing half to surround and close the bracket on the workbench surface, solving the problem that the cutting tool needs to move and fall during operation, and improving the use safety of the mounting bracket.

[0044] In short, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
