Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to a woodworking table saw. Background Technology

[0002] Table saws are commonly used cutting equipment in woodworking, widely applied in construction, decoration, and furniture manufacturing. Existing traditional table saws typically have a fixed structure, large size, and heavy weight. While they possess a certain degree of stability and cutting ability, they present inconveniences in practical use. Especially during high-rise building construction, table saws need to be transported to specific floors. The bulky nature of traditional table saws makes them difficult to disassemble or fold, leading to transport difficulties, increasing the labor intensity of construction workers, and impacting construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies, such as traditional table saws being mostly steel structures, large in size and heavy in weight, making them inconvenient to transport during high-rise building construction, and to provide a woodworking table saw.

[0004] In a first aspect, the present invention provides a woodworking table saw, including a tabletop, wherein a mounting groove is vertically formed in the middle of the tabletop, a pair of mounting seats are provided in the mounting groove, a mounting plate is detachably connected above the mounting seats, and a table saw body is detachably connected below the mounting plates;

[0005] The mounting plate is provided with an opening slot, which allows the saw blade of the table saw body to pass through;

[0006] It also includes table legs, the top of which is hinged to the bottom of the tabletop, and the middle of which is connected to the bottom of the tabletop by a diagonal brace, the diagonal brace being a two-bar structure.

[0007] This utility model provides a woodworking table saw. In this application, table legs are connected to the bottom of the tabletop, and a diagonal brace is provided between the middle of the table legs and the bottom of the tabletop. That is, the top of the table leg is connected to the bottom of the tabletop, and the middle of the table leg is connected to the bottom of the tabletop via the diagonal brace, forming a triangular structure, which improves the stability of the entire woodworking table saw. The connection between the tabletop and the table legs is hinged, allowing the table legs to rotate towards or away from the tabletop through the hinge point. The diagonal brace is a two-bar structure, and since two-bars themselves have the characteristic of being able to rotate... The table legs are hinged to the tabletop and legs via a two-bar linkage, allowing the legs to rotate 90°. When the legs are extended, the two-bar linkage extends synchronously until they are in a straight line, at which point the legs are perpendicular to the tabletop (the tabletop, legs, and diagonal braces form a triangular structure). When the legs are retracted, the hinge between the tabletop and legs presses them down, causing the diagonal braces to fold under force, thus allowing the legs to rotate and fold. This allows the entire device to be folded into a flat state when not in use, facilitating transport and storage.

[0008] Preferably, the bottom of the tabletop is provided with a first hinge seat, one end of the diagonal brace is connected to the bottom of the tabletop through the first hinge seat, and the other end is hinged to the side wall of the table leg.

[0009] Preferably, the diagonal brace includes a first connecting rod, one end of which is hinged to the table leg and the other end of which is hinged to a second connecting rod, the end of which away from the first connecting rod is hinged to the first hinge seat.

[0010] The first and second links form a two-link structure, which allows the table legs to fold when retracted, saving storage space and facilitating transportation and handling. At the same time, when the table legs are unfolded, the two-link structure provides support for the tabletop and table legs, providing stability for the woodworking table saw.

[0011] Preferably, the mounting plate is further provided with a third threaded hole; the table saw body includes a handheld cutter, the handheld cutter includes a motor, the motor is symmetrically provided with mounting ear plates, the mounting ear plates are vertically provided with a fourth threaded hole adapted to the third threaded hole, and the table saw body is connected to the mounting plate through the third threaded hole and the fourth threaded hole.

[0012] The threaded hole connection structure allows for easy and quick installation of handheld cutting machines under the mounting plate, and also enables rapid disassembly when necessary, enhancing the modularity and flexibility of the woodworking table saw.

[0013] Preferably, each of the table legs is provided with an anti-slip pad on its bottom.

[0014] Improve the overall structural stability of the woodworking table saw and prevent it from shifting due to vibration during operation.

[0015] Preferably, a plurality of second hinge seats are provided under the tabletop, the number and position of the second hinge seats correspond to the number and position of the table legs, and the end of each table leg facing the tabletop is provided with a hinge hole, the hinge hole and the second hinge seat are connected by a pivot.

[0016] The hinged structure allows the table legs to rotate and fold relative to the tabletop, so that the table legs can be folded up when not in use, greatly reducing the overall size and making it easier to store and move equipment. It is especially suitable for construction scenarios where space is limited or frequent movement is required.

[0017] Preferably, the tabletop is made of wood.

[0018] Using a wooden structure for the tabletop is lighter than using a traditional steel structure, making it easier for construction workers to move.

[0019] Preferably, the table legs are made of alloy.

[0020] The table legs were made of alloy, which improved the overall structural strength of the woodworking table saw.

[0021] Preferably, the tabletop is covered with plywood, and the shape of the plywood is consistent with the shape of the tabletop.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a woodworking table saw. In this application, table legs are connected to the bottom of the tabletop, and a diagonal brace is provided between the middle of the table legs and the bottom of the tabletop. That is, the top of the table legs is connected to the bottom of the tabletop, and the middle of the table legs is connected to the bottom of the tabletop via the diagonal brace, forming a triangular structure, which improves the stability of the entire woodworking table saw. The connection between the tabletop and the table legs is a hinge, allowing the table legs to rotate towards or away from the tabletop through the hinge point. The diagonal brace itself is a two-bar structure, and because two-bar structures are inherently capable of rotation... The mechanism utilizes a two-bar linkage that engages with the hinges of the tabletop and legs, allowing the legs to rotate 90°. When the legs are extended, the two-bar linkage extends synchronously until they are in a straight line, at which point the legs are perpendicular to the tabletop (the tabletop, legs, and diagonal braces form a triangular structure). When the legs are retracted, the hinges between the tabletop and legs press down on them, causing the diagonal braces to fold under stress, thus enabling the legs to rotate and fold. This allows the entire device to be folded into a flat state when not in use, facilitating transport and storage. Attached Figure Description

[0043] Example 1

[0044] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 and Figure 11 The table saw shown includes a tabletop 1 for mounting the table saw body 2. The tabletop 1 has a vertically formed mounting groove 11 in its center. A pair of mounting seats 12 are provided in the mounting groove 11. A mounting plate 13 is detachably connected to the mounting seats 12. The table saw body 2 is detachably connected to the mounting plate 13. The table saw body 2 includes a handheld cutter 21 with a saw blade. The mounting plate 13 has a vertically formed opening groove 131 for the saw blade to pass through the tabletop 1.

[0045] Several second hinge seats 15 are provided under the tabletop 1. Each hinge seat is hinged to a table leg 3, so that the table leg 3 can be hinged to the tabletop 1 through the hinge seat and can be flipped. A diagonal brace 4 is hinged to the middle of the table leg 3. One end of the diagonal brace 4 is hinged to the table leg 3, and the other end is hinged to a first hinge seat 14. The first hinge seat 14 is located on the bottom surface of the tabletop 1.

[0046] Furthermore, the diagonal brace 4 is a two-bar structure. Specifically, the diagonal brace 4 includes a first connecting rod 41, one end of which is hinged to the table leg 3. One end of the first connecting rod 41 is hinged to the table leg 3, and the other end is hinged to a second connecting rod 42. The end of the second connecting rod 42 that is not hinged to the first connecting rod 41 is hinged to the first hinge seat 14. Since the diagonal brace 4 is composed of the first connecting rod 41 and the second connecting rod 42 (two-bar structure), the diagonal brace 4 can rotate at the hinge point of the first connecting rod 41 and the second connecting rod 42. Because one end of the first connecting rod 41 is hinged to the table leg, and the end of the second connecting rod 42 that is not hinged to the first connecting rod 41 is hinged to the first hinge seat 14, and the top of the table leg is hinged to the bottom of the tabletop 1, this allows the construction personnel to rotate the table leg (simultaneously adjusting the first connecting rod 42) by bending the table leg. Force is applied at the hinge of link 41 and link 42, allowing the entire table leg to flip towards the tabletop 1, thus achieving folding. When the table leg needs to be changed from a folded to an unfolded position, the table leg is bent, and the hinge between the table leg and the tabletop 1 makes the table leg perpendicular to the tabletop 1. At this time, the diagonal brace 4 moves synchronously, and the first link 41 and the second link 42 change from the folded position in a straight line, thereby enhancing the structural stability of the entire woodworking table saw. The first link 41 and the second link 42 form a two-link structure, which allows the table leg 3 to fold when it is retracted, saving storage space and facilitating transportation and handling. At the same time, when the table leg 3 is unfolded, the two-link structure can provide support for the tabletop 1 and the table leg 3, providing stability to the woodworking table saw.

[0047] In one or more embodiments, each mounting base 12 is vertically provided with a plurality of first threaded holes 121, and the mounting plate 13 located on the mounting base 12 is provided with second threaded holes 132 that are adapted to the first threaded holes 121. The first threaded holes 121 and the second threaded holes 132 are connected by bolts, thereby enabling the mounting plate 13 and the mounting base 12 to be detachably connected. Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown.

[0048] In one or more embodiments, the handheld cutting machine 21 further includes a motor 211 for starting, on which a plurality of mounting lugs 22 are symmetrically arranged, each mounting lug 22 having a fourth threaded hole 221; the mounting plate 13 has a vertically arranged third threaded hole 133 adapted to the fourth threaded hole 221, the third threaded hole 133 and the fourth threaded hole 221 being connected by bolts, thereby realizing a detachable connection between the table saw body 2 and the mounting plate 13. The threaded hole connection structure allows the handheld cutting machine 21 to be conveniently and quickly installed under the mounting plate 13, and can also be quickly disassembled when necessary, improving the modularity and flexibility of the woodworking table saw. Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown.

[0049] In one or more embodiments, each table leg 3 is provided with an anti-slip pad 32 at its bottom to improve the overall structural stability of the woodworking table saw and prevent displacement of the woodworking table saw due to vibration during operation. Figure 9 As shown.

[0050] In one or more embodiments, a plurality of second hinge seats 15 are provided under the tabletop 1. The number and position of the second hinge seats 15 correspond to the number and position of the table legs 3. A hinge hole 31 is provided at the end of each table leg 3 facing the tabletop 1. The hinge hole 31 is connected to the second hinge seat 15 via a pivot 5. Figure 10 and Figure 11 As shown

[0051] In one or more embodiments, the tabletop 1 is a wooden structure. Setting the tabletop 1 as a wooden structure is lighter than the traditional steel structure, making it easier for construction workers to move.

[0052] Furthermore, the table legs 3 are made of alloy, which improves the overall structural strength of the woodworking table saw.

[0053] Optionally, a crossbar 7 can be bolted between two adjacent table legs 3. The crossbar 7 limits the movement of the two adjacent table legs 3, improving the tensile strength of the entire woodworking table saw. When folding is required, the crossbar 7 can be disassembled. Figure 12 As shown.

[0054] In one or more embodiments, plywood 6 is laid on the tabletop 1, and the shape of plywood 6 is consistent with the shape of the tabletop 1. When plywood 6 wears out due to long-term use, plywood 6 can be replaced individually without replacing the entire tabletop 1, reducing maintenance costs and improving maintenance efficiency. Figure 1 As shown.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
