[0002] In woodworking, track saws are often used with track plates to achieve straight-line cutting of wood. Track plates are usually fixed to the surface of the wood by non-slip mats or clamps and serve to guide the hand saw along the set path, thereby improving cutting accuracy and operation stability. However, existing track plates are inconvenient to adjust when used on wood of different thicknesses or sizes, affecting adaptability and construction efficiency.

DETAILED DESCRIPTION

[0038] The present application will be described below with reference to the accompanying drawings, which show several embodiments of the present application. It should be understood, however, that the present application can be presented in various different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully inform those skilled in the art of the scope of protection of the present application. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0039] First embodiment:

[0040] A track saw track plate adjusting device is provided, which comprises a track plate 50 and a rotating device 10. A gap is provided between the track plate 50 and a worktable top 80 for processing a plate 90, so that the plate 90 can pass through the gap. The track saw can move along the extension direction of the track plate 50 and cut the plate 90. The track plate 50 is rotatably connected to the table top 80 by the rotating device 10. Please refer to Figures 2 to 4 The rotating device 10 moves in the normal direction of the table top 80 to adjust the gap between the track plate 50 and the table top 80, so as to adapt to plates 90 of different thicknesses.

[0041] Please refer to Figure 1The rotating device 10 comprises an upper plate 11 and a lower plate 12, the upper plate 11 is rotatably connected with the lower plate 12, and the maximum opening angle is preferably 90 degrees. The opening angle refers to the angle formed when the upper plate 11 is opened from the parallel state with the lower plate 12. The upper plate 11 is fixedly connected with one side of the track plate 50. In order to adapt to the use requirements of left-cutting and right-cutting track saws, both ends of the track plate 50 can be connected with the upper plate 11, and the free end of the track plate 50 is the starting end of the cutting process.

[0042] The lower plate 12 is connected with the workbench top 80 by a track group. Although the use of damping sliding rails can improve the operation experience, but the damageability is high. Therefore, as shown in Figure 3 , a track group composed of a sliding rail 22 and a sliding bar 121 is provided: the side of the lower plate 12 facing the top 80 is provided with a plurality of sliding bars 121, and the side of the top 80 is provided with sliding rails 22 corresponding to the sliding bars 121; the lower plate 12 is provided with a tightening wrench 122 penetrating the lower plate 12 and the sliding bar 121 and abutting on the sliding rail 22. After adjusting to the appropriate spacing between the track plate 50 and the top 80, tighten the tightening wrench 122 to fix the spacing.

[0043] Specifically, referring to Figure 5 , a pair of hinge seats are arranged at the corresponding positions of the upper plate 11 and the lower plate 12, respectively. The bearing center axes of the two groups of hinge seats are coaxially arranged, and the bearings of the two groups of hinge seats are connected by a shaft rod, so as to realize the rotatable connection between the upper plate 11 and the lower plate 12.

[0044] Referring to Figure 7 , due to the heavy hand saw body, the track plate 50 is easy to be excessively turned over under the action of gravity during the turning process, and there is a great safety hazard. Therefore, a limit stop 40 is arranged within the opening angle range of the upper plate 11 and the lower plate 12, for adjusting the minimum opening angle.

[0045] The limit stop 40 comprises an inclined surface 41 and a top rod 42, preferably, the limit stop 40 is arranged on the lower plate 12, the inclined surface 41 faces the upper plate 11, and the top rod 42 is arranged on the side facing the upper plate 11 and can adjust the extension length thereof and abut on the turned-over upper plate 11.

[0046] Specifically, the top rod 42 is a screw rod with a colloid material head, and the screw rod is threadedly connected with the inclined surface 41.

[0047] In order to ensure that the extension direction of the track group is kept coincident with the normal direction of the table 80, and to avoid the inclination caused by the self-installation of the consumer, the rotating device 10 is connected with the table 80 through the positioning plate 20. The two plate surfaces of the positioning plate 20 are arranged at 90 degrees and abut against the outer edge of the table 80, wherein the plate surface at the upper part of the positioning plate 20 is kept horizontally arranged with the table 80, and the plate surface at the lower part is kept vertically arranged. The slide rail 22 of the track group is installed on the vertical plate surface at the lower part of the positioning plate 20; in order to make the connection between the positioning plate 20 and the lateral surface of the table 80 more firm, the plate surface at the lower part of the positioning plate 20 is provided with the adjusting positioning hole 23, and the screw passes through the adjusting positioning hole 23 to fixedly connect the positioning plate 20 with the table 80.

[0048] In a possible implementation, as shown in Figure 2 , the end stroke of the track plate 50 is provided with the rubber block 60 or the stop block 70. The rubber block 60 is preferably a circular rubber ring with elasticity, which is used to prevent the track saw from sliding out of the track plate 50 when being pushed to the end. The stop block 70 is arranged on the side of the rubber block 60 away from the stroke end of the track plate 50, and has a height higher than that of the rubber block 60. After the track plate 50 is turned over, the stop block 70 plays a role in clamping the track saw and preventing the track saw from turning out of the track plate 50.

[0049] In a possible implementation, in combination with Figure 4 and Figure 7 , the upper end of the lower plate 12 is provided with the abutting part 123, and the front end of the upper plate 11 is provided with the top holding part 112. When the upper plate 11 is turned over to be at 90 degrees with the lower plate 12, the end surface of the top holding part 112 abuts against the side surface of the abutting part 123, so that the opening angle between the upper plate 11 and the lower plate 12 can be effectively prevented from being greater than 90 degrees, and the track plate 50 can be kept horizontal with the table 80.

[0050] In a possible implementation, the side of the track plate 50 away from the working surface of the track saw is connected with one end of the inclined pull plate 31, and the other end of the inclined pull plate 31 is fixedly connected with the upper plate 11 of the rotating device 10, so that the track plate 50 can be kept perpendicular to the outer edge of the table 80, that is, the extension direction of the track plate 50 can be kept perpendicular to the extension direction of the track group.

[0051] Usage:

[0052] Please refer to Figure 6, first connect the rotating device 10 with the track plate 50, make the sliding bar 121 on the rotating device 10 insert into the sliding rail 22 on the positioning plate 20. Then turn over the track plate 50 to make it stand vertically, lay the plate 90 to be processed on the table 80, make the plate 90 abut against the ruler 21 which is arranged perpendicularly to the track plate 50, and the ruler 21 is also provided with scale lines which can quickly determine the length of the cut plate 90, then turn over the track plate 50 back to the original position to make it fall above the plate 90. Move the rotating device 10 up and down to make the track plate 50 horizontally adhere to the surface of the plate 90, and adjust the locking wrench 122 to lock the track group. After that, the track saw starts cutting from the side far away from the rotating device 10.

[0053] After the cutting is completed, if the plate 90 with different thickness needs to be replaced, the track plate 50 can be turned over to the vertical state again. At this time, the block 70 cooperates with the rubber block 60 to effectively constrain the track saw to prevent it from sliding out of the track plate 50; at the same time, the top rod 42 of the limiter 40 can be adjusted to the appropriate position to limit the minimum opening angle of the rotating device 10, so as to avoid the track saw driving the track plate 50 to turn over excessively due to gravity. The operation steps after the track plate 50 is returned to the original position are the same as the above, and the next round of cutting operation can be continued.

[0054] A guide strip is arranged between the two rulers 21 on the positioning plate 20 and below the track plate 50, and the outer edge of the guide strip is flush with the outer edges of the two rulers 21, so that when the plate 90 is pushed, the plate 90 is prevented from being inserted between the two rulers 21 with the side skewed.

[0055] Second embodiment:

[0056] Different from the first embodiment, please refer to Figures 8 to 10 One side of the track plate 50 is fixedly connected with the angle plate 32, and the other side of the angle plate 32 is slidably connected with the upper plate 11 of the rotating device 10 through the second hand wheel 35. The track plate 50 is rotatably connected with the upper plate 11 through the fixed shaft 33, and when the track plate 50 drives the angle plate 32 to rotate around the fixed shaft 33, the second hand wheel 35 moves in the arc-shaped second sliding groove 321 arranged on the angle plate 32.

[0057] The second hand wheel 35 is used to adjust the clamping force between the angle plate 32 and the upper plate 11, so as to realize the locked or unlocked state between them.

[0058] In a possible implementation manner, the track plate 50 is connected with the upper plate 11 through the first hand wheel 34. When the first hand wheel 34 and the second hand wheel 35 are simultaneously screwed, the stability of the track plate 50 can be effectively enhanced, and the possibility of left and right swinging of the track plate 50 is reduced. When the track plate 50 rotates around the fixed shaft 33, the first hand wheel 34 will slide in the arc-shaped first sliding groove 111 arranged on the upper plate 11.

[0059] In a possible implementation, the angle plate 32 is further provided with a scale line for indicating the rotation angle of the track plate 50, and the rotation angle of the track plate 50 is determined by the pointer on the second hand wheel 35 pointing to the scale line on the angle plate 32.

[0060] Although exemplary embodiments of the present application have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments without departing from the spirit and scope of the present application in its broadest form. Therefore, all changes and modifications are intended to be included within the scope of the present application as defined in the appended claims.
