Description

Technical Field

[0001] The utility model relates to the field of woodworking saw benches, in particular to a push rod switching mechanism applied to a saw bench. Background Art

[0002] When a woodworker uses a saw bench for operation, in order to facilitate fixed-length and directional sawing of materials, a woodworking backstop device is usually installed on the saw bench. 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. In this way, the saw bench needs to be equipped with two push rods for using the backstop, resulting in higher costs, occupying more area, and interfering with woodworking operations at the same time. Summary of the Utility Model

[0003] To solve the above problems, the present technical solution provides a push rod switching mechanism applied to a saw bench.

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

[0005] A push rod switching mechanism applied to a saw bench includes a push rod movable on the saw bench. A positioning structure is provided on one side of the push rod, and a locking structure is provided on the other side. The positioning structure is used to cooperate with one side of a first slide rail or a second slide rail. When the positioning structure cooperates with any one of the slide rails, the locking structure works to install the push rod on the corresponding slide rail.

[0006] In some embodiments, the positioning structure includes a positioning plate connected to the profile of the push rod, and further includes a positioning groove provided on a slider that cooperates with the first slide rail. The positioning plate is inserted into the positioning groove to achieve positioning.

[0007] In some embodiments, the locking structure includes a pushing component. A slider that cooperates with the first slide rail on the other side also has a positioning groove. When the pushing component works, it approaches or moves away from the positioning groove to achieve locking or unlocking.

[0008] 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.

[0009] In some embodiments, the bracket is provided with a limiting groove, and the moving part is provided with a limiting part extending into the limiting groove.

[0010] In some embodiments, a screw passes through the moving part, and the screw is connected to the pushing part, so that when the screw is rotated, the pushing part can be driven to approach the positioning groove.

[0011] In some embodiments, a first articulated arm is articulated to the moving part, a second articulated arm is articulated to the bracket, and the first articulated arm and the second articulated arm are articulated to each other.

[0012] In some embodiments, a balance bracket connected to the sliders on both sides is further included.

[0013] The beneficial effects of the present application are as follows:

[0014] In the present application, positioning grooves are provided on both sides of the slide rails in the transverse cutting direction and the longitudinal 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 a locking structure. Therefore, only one push rod is required for the saw table of the present application. By disassembling the locking structure of the push rod and then locking it on the corresponding slide rail, the positioning backstop for transverse cutting and longitudinal cutting can be realized. After locking, it can follow 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.

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clear, the present invention will be further described in detail below 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.

[0022] Please refer to Figures 1 - 5As shown in the figure, the push rod switching mechanism applied to the saw table 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 slide rail, the locking structure 3 works to install the push rod 1 on the corresponding slide rail.

[0023] 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 positioning groove, and the positioning groove on the other side can be locked by the locking structure. Therefore, only one push rod is needed 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.

[0024] When cross-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 cross-cutting, the push rod follows the movement of the first slide rail. Similarly, when vertical-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.

[0025] 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.

[0026] For 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.

[0027] 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.

[0028] For 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.

[0029] 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.

[0030] As described above, specifically, the moving part 33 is hinged with a first hinge arm 38, and the bracket 32 is hinged with a second hinge arm 39. 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.

[0031] 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.

[0032] 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 principles and basic structures that are the same as or similar to those of the present application are all within the protection scope of the present application.
