Description

Technical Field

[0001] The utility model relates to the field of woodworking saw tables, in particular to a push rod assembly structure applied to the cross-cutting direction of a saw table. Background Art

[0002] When a woodworker uses a saw table for work, in order to facilitate the fixed-length and fixed-direction sawing of materials, a woodworking backstop device is usually installed on the saw table. When installing the backstop device, there are usually two postures, that is, the backstop is perpendicular and parallel to the saw blade. When the backstop is perpendicular to the saw blade, it is commonly called cross-cutting. When the backstop is parallel to the saw blade, it is commonly called vertical cutting. If a push rod needs to be flipped up and down, there will be a shaking gap, or after disassembly, it needs to be recalibrated. If it is used alternately for cross-cutting and vertical cutting, then the push rod needs to be leveled, otherwise it will affect the non-parallelism between the front and back of the vertical cutting scale and the saw blade, and the cross-cutting cannot be 90 degrees perpendicular. Thus, it affects the cutting parallel diagonal dimension. Summary of the Utility Model

[0003] To solve the above problems, the present technical solution provides a push rod assembly structure applied to the cross-cutting direction of a saw table.

[0004] To achieve the above object, the present technical solution is as follows:

[0005] A push rod assembly structure applied to the cross-cutting direction of a saw table includes a positioning structure on one side below the push rod, and further includes a second slide rail arranged in the cross-cutting direction. The second slide rail is provided with a slider, the slider is provided with an adjusting plate, and an adjusting part connected to the positioning structure is arranged in the adjusting plate.

[0006] In some embodiments, the positioning structure includes a positioning plate connected to the profile of the push rod. The positioning plate is provided with a groove, and the adjusting part is provided with a linkage shaft that can extend into the groove.

[0007] In some embodiments, the adjusting part is driven by a driving part.

[0008] In some embodiments, the driving part is a screw threadedly connected to the adjusting plate and connected to the adjusting part.

[0009] In some embodiments, it further includes a locking structure located on the other side below the push rod for locking on the second slide rail.

[0010] In some embodiments, the locking structure includes a pushing component. The slider cooperating with the second slide rail on the other side is provided with a positioning groove, and when the pushing component works, it approaches or moves away from the positioning groove to achieve locking or unlocking.

[0011] In some embodiments, the pushing component includes a bracket, a moving part that can slide horizontally on the bracket, and a pushing part connected to the moving part for extending into the positioning groove.

[0012] The beneficial effects of this application are as follows:

[0013] When the push rod needs to be assembled in the cross-cutting direction after being disassembled in this application, the positioning structure of the push rod is matched with the adjusting part. Since the adjusting part allows the worker to push forward and backward, the push during the advancement will drive the positioning structure and then drive one end of the push rod to swing by a certain amplitude. Finally, the push rod will use the other end as a reference point to make one end straight and achieve the purpose of equalizing both ends, preventing the influence on the scale reading, and finally making the cut plate reach 90 degrees vertically, eliminating the need for frequent adjustment in the later stage and achieving long-term positioning.

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following further details the present invention with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please refer to Figures 1-5 As shown, a saw table structure includes a push rod 1 that can move on the saw table. A positioning structure 2 is provided on one side of the push rod 1, and a locking structure 3 is provided on the other side. The positioning structure 2 is used to cooperate with one side of the first slide rail 4 or the second slide rail 5. When the positioning structure 2 cooperates with any one of the slide rails, the locking structure 3 works to install the push rod 1 on the corresponding slide rail.

[0024] In this application, positioning grooves are provided on both sides of the slide rails in the cross-cutting direction and the vertical-cutting direction. Then, the positioning plate of the push rod can be applied to any one of the positioning grooves, and the positioning groove on the other side can be locked by the locking structure. Therefore, only one push rod is required for the saw table of this application. By disassembling the locking structure of the push rod and then locking it on the corresponding slide rail, the positioning backrest for cross-cutting and vertical-cutting can be realized. After locking, it can follow the movement of the slide rail, reducing the cost. At the same time, the area of the saw table is enlarged, which is beneficial to the use of the saw table area.

[0025] When vertical cutting is required, insert the positioning part of the push rod into the positioning groove of the slider that cooperates with the first slide rail, and then lock the locking structure with the slider of the first slide rail on the other side. Thus, when vertical cutting, the push rod follows the movement of the first slide rail. Similarly, when cross-cutting is required, insert the positioning plate into the positioning groove of the slider of the second slide rail, and also use the locking structure to follow it, so as to achieve following movement.

[0026] Specifically, the positioning structure 2 includes a positioning plate 21 connected to the profile of the push rod 1, and also includes a positioning groove 23 provided on the slider 22 that cooperates with the first slide rail 4. The positioning plate 21 is inserted into the positioning groove 23 to achieve positioning.

[0027] As a specific embodiment of the locking structure, please refer to Figure 2 , the locking structure 3 includes a pushing component 31. The slider 22 that cooperates with the first slide rail 4 on the other side also has a positioning groove 23. When the pushing component 31 works, it approaches or moves away from the positioning groove 23 to achieve locking or unlocking. This embodiment only needs to use a horizontally movable pushing component to push it into the groove, that is, any component with horizontal movement ability can be used.

[0028] As another embodiment of the locking structure, the pushing component 31 includes a bracket 32, and a moving part 33 that can slide horizontally on the bracket 32. It also includes a pushing part 34 connected to the moving part 33 and used to extend into the positioning groove 23. The moving part can move horizontally on the bracket. As long as power is applied to the moving part, the moving part can drive the pushing part to approach the groove to achieve locking. Similarly, the moving part can also drive the pushing part to leave the groove.

[0029] As the optimal embodiment of the locking structure, please refer to Figure 4, the bracket 32 is provided with a limiting groove 35, and the moving part 33 is provided with a limiting part 36 extending into the limiting groove 35. Under the action of the limiting structure, the moving part can only move horizontally.

[0030] As described above, specifically, a screw 37 passes through the moving part 33, and the screw 37 is connected to the pushing part 34, so that when the screw 37 is rotated, the pushing part 34 can be driven to approach the positioning groove 23. The worker rotates the screw and then drives the pushing part to press the positioning groove to achieve locking. During this process, the moving part can only move horizontally through the cooperation of the limiting groove and the limiting part.

[0031] As described above, specifically, the moving part 33 is hinged with a first hinge arm 38, the bracket 32 is hinged with a second hinge arm 39, and the first hinge arm 38 and the second hinge arm 39 are hinged to each other. During the movement of the moving part, the flipping of the two hinge arms is used to achieve support and reinforcement.

[0032] In the above embodiment, a balance frame 6 connected to the two side sliders 22 is further included to ensure that the two side sliders are in the same horizontal position, so that the two ends of the push rod are always flush, avoiding affecting the scale reading.

[0033] This application further includes a push rod assembly structure applied to the cross-cutting direction of the saw table, including a positioning structure 2 on one side below the push rod 1, and a second slide rail 5 arranged in the vertical cutting direction. The second slide rail 5 is provided with a slider 22, and the slider 22 is provided with an adjusting plate 7. The adjusting plate 7 is provided with an adjusting part 71 connected to the positioning structure 2.

[0034] When this application needs to assemble the push rod in the cross-cutting direction after disassembling the push rod, the positioning structure of the push rod is matched with the adjusting part. Since the adjusting part allows the worker to move forward and backward, when pushing forward, it will drive the positioning structure and then drive one end of the push rod to swing by a certain amplitude. Finally, the push rod will use the other end as a reference point to make one end straight and achieve the purpose of both ends being flush, preventing affecting the scale reading.

[0035] The movement of the adjusting part will be described below. Please refer to Figures 6-7 , the positioning structure 2 includes a positioning plate 21 connected to the profile of the push rod 1. The positioning plate 21 is provided with a groove 72, and the adjusting part 71 is provided with a linkage shaft 73 that can extend into the groove 72.

[0036] The positioning plate is provided with a groove, which is opened from the lower end opening towards the middle of the positioning plate. When assembling the push rod, the groove of the positioning plate can be aligned with the linkage shaft and put in. Then, when the slider moves, it will drive the positioning plate and the push rod to slide through the linkage shaft, with higher assembly efficiency and more convenient disassembly. Secondly, the push rod can also be swung and adjusted by moving the adjusting part. When not adjusted, the adjusting part and the positioning plate are relatively stationary.

[0037] One end of the push rod is matched with the slider on one side through the positioning plate, and the other end is matched with the slider on the other side through the locking structure, so as to realize the sliding of the push rod assembled on the slide rail.

[0038] In this embodiment, the adjusting part 71 is driven by the driving part 74, and the worker operates the driving part to drive the adjusting part to move.

[0039] In this embodiment, the driving part 74 is a screw threadedly connected to the adjusting plate 7 and connected to the adjusting part 71. The worker rotates the screw to push the adjusting part to move forward and backward for adjustment. If no force is applied to the screw, due to the existence of the thread, the adjusting part and the positioning plate are relatively stationary.

[0040] The above are only the preferred embodiments of the present application, and are not used to limit the scope of implementation of the present application. Other embodiments with the same or similar principles and basic structures as the present application are within the protection scope of the present application.
