Description

Technical Field

[0001] This invention relates to a track pusher, and more particularly to a sliding tool holder damping anti-disengagement track pusher with adjustable tool wheel angle. Background Technology

[0002] A tile track cutter is a manual tool used for cutting tiles. It is widely used in tile installation due to its ease of operation and high cutting precision. By manually pushing the sliding block, the cutter wheel moves at a constant speed across the tile surface, leaving scratches using the wheel's hardness. Pressure is then applied by a pressure block, causing the tile to break along these scratches, thus achieving the cutting process. Existing track cutters typically use locking screws to lock the track cutter against the graduated bar. However, these screws are prone to loosening, causing the sliding cutter holder to easily disengage from the graduated bar, resulting in damage or loss due to impact. Summary of the Invention

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

Figure 1-5 As shown, it includes a guide rail and a movable seat that can move relative to the guide rail. The movable seat is provided with a scale bar 1. The scale bar 1 is provided with a sliding tool holder 2 that can move relative to the scale bar 1. One side of the sliding tool holder 2 is provided with an adjustable angle tool wheel assembly. The sliding tool holder 2 is provided with a damping locking structure. One end of the scale bar 1 is provided with an anti-detachment end cap 3. The damping locking structure includes a damping block cover 4 provided at the upper end of the sliding tool holder 2. The lower side of the damping block cover 4 is connected to the sliding tool holder damping block 6 that abuts against the scale bar 1 through a damping block spring 5.

[0022] The sliding tool holder 2 is provided with a guide groove 7 corresponding to the sliding tool holder damping block 6.

[0023] The anti-detachment end cap 3 includes an anti-detachment end cap bottom cap 3.1 fixed to the end of the scale bar 1 by bolts. An anti-detachment end cap top cap 3.2 is provided on one side of the anti-detachment end cap bottom cap 3.1. A first cavity 3.3 is formed horizontally between the anti-detachment end cap bottom cap 3.1 and the anti-detachment end cap top cap 3.2. A second cavity 3.4 is provided vertically on the upper and lower sides of the first cavity 3.3. An anti-detachment buckle assembly for limiting the sliding knife holder 2 is provided in the second cavity 3.4. An unlocking button assembly for controlling the unlocking of the anti-detachment buckle assembly is provided in the first cavity 3.3.

[0024] The release button assembly includes a release button spring 3.5 connected to the bottom cover 3.1 of the anti-detachment end cap. A release button 3.6 is provided on one side of the release button spring 3.5. The release button 3.6 has slots 3.61 at both the upper and lower ends. One horizontal end of the release button 3.6 has a mounting groove 3.62 for mounting the release button spring 3.5. The other horizontal end of the release button spring 3.5 has a pressing part 3.63 that penetrates the top cover 3.2 of the anti-detachment end cap. A limiting part 3.64 is provided on one side of the pressing part 3.63.

[0025] The anti-detachment buckle assembly includes an anti-detachment buckle spring 3.7 connected to the anti-detachment end cap 3.2. An anti-detachment buckle 3.8 is provided on one side of the anti-detachment buckle spring 3.7. The upper end of the anti-detachment buckle 3.8 is provided with a locking block 3.81 that penetrates the anti-detachment end cap 3.2. The lower end of the anti-detachment buckle 3.8 is provided with a locking block 3.82 corresponding to the locking groove 3.61. Mounting parts 3.83 are provided on both horizontal sides of the anti-detachment buckle 3.8. The mounting parts 3.83 are provided with guide posts 3.84 that guide and limit the anti-detachment buckle spring 3.7.

[0026] The card block 3.82 has an inclined guide surface at one end.

[0027] The cutter wheel assembly includes an adjustable cutter holder 8 located on one side of the sliding cutter holder 2. The contact surface between the adjustable cutter holder 8 and the sliding cutter holder 2 is provided with a longitudinally arranged fulcrum 15. A vertically arranged cutter wheel mounting rod 9 is provided in the middle of the adjustable cutter holder 8. A cutter wheel 10 is provided at the lower end of the cutter wheel mounting rod 9. A locking screw 11 for locking the cutter wheel mounting rod 9 is provided on one side of the cutter wheel mounting rod 9. Angle adjustment screws 12 are provided at the upper and lower ends on both sides of the adjustable cutter holder 8.

[0028] The sliding tool holder 2 and the adjusting tool holder 8 have a fulcrum groove 13 in the middle of their contact surface, which corresponds to the fulcrum 15. The fulcrum groove 13 has angle adjusting screw holes 14 on both sides, which correspond to the angle adjusting screws 12.

[0029] The working principle of this application is as follows: A damping locking structure is used to achieve self-locking between the sliding tool holder 2 and the scale bar 1. Without external force, the sliding tool holder 2 cannot move relative to the scale bar 1. The sliding tool holder damping block 6 in the damping locking structure abuts against the upper surface of the scale bar 1 under the action of the damping block spring 5. Simultaneously, the damping block spring 5 exerts an upward force on the damping block cover 4, causing the sliding tool holder 2 to press firmly against the lower surface of the scale bar 1, thus achieving self-locking. If it is necessary to move the sliding tool holder, the sliding tool holder 2 is pressed, causing it to separate from the lower surface of the scale bar 1, leaving only the sliding tool holder damping block 6 in contact with the scale bar. At this point, the sliding tool holder can be moved easily. Furthermore, this application provides anti-detachment end caps at both ends of the scale bar 1 to achieve double protection. When it is necessary to open the anti-detachment end cap 3 so that the sliding tool holder 2 can disengage relative to the scale bar, pressing the release button 3.6 causes the release button 3.6 to move along the first cavity 3.3 and compress the release button spring 3.5. During the movement of the release button 3.6, the locking block 3.82 on the lower side of the anti-detachment buckle 3.8 will engage in the slot 3.61, thereby causing the anti-detachment buckle 3.8 to move towards the first cavity 3.3. The locking block 3.81 on the anti-detachment buckle 3.8 cannot lock the sliding tool holder 2. If it is necessary to lock the sliding tool holder 2, the release button 3.6 is released, allowing it to reset under the action of the release button spring 3.5. During reset, the elastic force of the release button spring 3.5 is greater than the elastic force of the anti-detachment buckle spring 3.7. One end of the locking block 3.82 has an inclined guide surface. When the release button 3.6 moves outward, the locking groove 3.61 causes the locking block 3.82 to move away from the first cavity 3.3, allowing the locking block 3.82 to extend outward and block the sliding tool holder, preventing it from detaching from the scale bar 1. This application also includes an adjustable tool wheel assembly, facilitating adjustment of the angle between the tool wheel and the track to ensure parallel alignment and straight-line drawing. Specifically, rotating the angle adjustment screw causes the adjusting tool holder 8 to rotate around the fulcrum 15 and the fulcrum groove 13, adjusting the tool wheel angle to ensure the angle between the tool wheel and the track, guaranteeing straight-line drawing.
