Description

Technical Field

[0001] The utility model relates to the technical field of paving tools, in particular to a track push knife. Background Art

[0002] During decoration work, workers need to lay tiles, glass and other decorations on the floor and walls. Due to the differences in the structure, shape and size of the buildings, workers often need to cut the decorations into specified sizes before use. The track push knife is a laying tool that can cut tiles, glass and other decorations.

[0003] For example, a push-knife tile cutting machine disclosed in CN217943844U includes a positioning guide slide bar, a push rod and a push-knife assembly, one end of the push rod is vertically fixed on the positioning guide slide bar, a plurality of guide wheels are provided on the bottom surface of the positioning guide slide bar, the rolling direction of the guide wheels is parallel to the positioning guide slide bar, a push-knife assembly is provided on the push rod, and the push-knife assembly is movably connected to the push rod. The push-knife tile cutting machine moves the push-knife assembly to cut the decorations by sliding the push rod on the positioning guide slide bar, and has a simple structure and low cost.

[0004] However, since the push rod is long and is generally made of aluminum, which has a certain elasticity, when the push blade assembly slides to the end of the decoration and is about to break contact with the decoration, the push blade assembly will have a tendency to sag suddenly. If the operator is not careful, the push blade at the bottom of the push blade assembly may collide with the ground on which the decoration is placed, thereby damaging the push blade. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a track push knife, which can use auxiliary wheels to reduce the collision between the knife wheel and the ground after cutting, so as to protect the knife wheel.

[0006] In order to solve the above technical problems, the technical solutions provided by the utility model are as follows:

[0007] A track push knife, comprising at least a base, a sliding assembly slidably connected to the base, a push rod fixedly arranged on the sliding assembly, the push rod being located on the side of the base, the length direction of the push rod being perpendicular to the sliding direction of the sliding assembly, a push knife assembly being arranged on the push rod, the push knife assembly being slidably connected to the push rod, a height-adjustable knife wheel being arranged at the bottom of the push knife assembly, characterized in that it also comprises:

Detailed implementation manners

[0027] The following further describes the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the mechanism or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0029] As Figure 1 shown, the track push knife of this embodiment at least includes a base 10, a sliding component 20 is slidably connected to the base 10, a push rod 30 is fixedly arranged on the sliding component 20, the push rod 30 is located at the side of the base 10, the length direction of the push rod 30 is perpendicular to the sliding direction of the sliding component 20, a push knife component 40 is arranged on the push rod 30, the push knife component 40 is slidably connected to the push rod 30, and a cutter wheel 41 with adjustable height is arranged at the bottom of the push knife component 40. An auxiliary wheel component 50 is also slidably connected to the push rod 30, a height-adjustable auxiliary wheel 51 is arranged at the bottom of the auxiliary wheel component 50, and the auxiliary wheel 51 has a certain elasticity.

[0030] In this embodiment, the push - knife assembly 40 is located between the base 10 and the auxiliary - wheel assembly 50. In this way, when the push rod 30 is pressed, the auxiliary - wheel assembly 50 and the base 10 can play a supporting role on both sides of the push - knife assembly 40, making the force on the cutter wheel 41 more uniform.

[0031] As Figure 2 shown, two guide rails 11 are arranged in parallel on both sides in the length direction of the base 10. A groove 101 is arranged on one side of the base 10 close to the push rod 30. A number of first fasteners 12 penetrating into the interior of the groove 101 are also arranged on the base 10.

[0032] As Figure 3 shown, rolling elements 21 which are in rolling connection with the guide rails 11 are arranged on the sliding assembly 20. Preferably, there are three rolling elements 21 for the sliding assembly 20 to be in rolling connection with each guide rail 11. Since the base 10 is relatively long and the length of the guide rail 11 is not enough to extend the entire base 10, multiple guide rails 11 need to be spliced. There may be a certain deviation in straightness when different guide rails 11 are spliced. Arranging three rolling elements 21 can ensure that when the sliding assembly 20 slides to the joint of different guide rails 11, at least two rolling elements 21 are located on the same guide rail 11, making the sliding smoother.

[0033] As Figure 4 shown, the push - knife assembly 40 includes a first fixing sleeve 42 sleeved on the push rod 30. A second fastener 43 is arranged between the first fixing sleeve 42 and the push rod 30. A cutter - wheel fixing member 44 is movably connected to the first fixing sleeve 42. A third fastener 45 is arranged between the cutter - wheel fixing member 44 and the first fixing sleeve 42. The cutter wheel 41 is arranged at the bottom of the cutter - wheel fixing member 44. In this way, the relative tightness between the first fixing sleeve 42 and the push rod 30 can be adjusted through the second fastener 43 to adjust the specific position of the push - knife assembly 40 on the push rod 30, and the relative position between the cutter - wheel fixing member 44 and the first fixing sleeve 42 can be adjusted through the third fastener 45 to adjust the up - and - down position of the cutter wheel 41.

[0034] As Figure 5 shown, the auxiliary - wheel assembly 50 includes a second fixing sleeve 52 sleeved on the push rod 30. A fourth fastener 53 is arranged between the second fixing sleeve 52 and the push rod 30. An auxiliary - wheel fixing member 54 is movably connected to the second fixing sleeve 52. A kidney - shaped hole 541 is arranged on the auxiliary - wheel fixing member 54. The auxiliary wheel 51 is arranged at the bottom of the auxiliary - wheel fixing member 54. In this way, the relative tightness between the second fixing sleeve 52 and the push rod 30 can be adjusted through the fourth fastener 53 to adjust the specific position of the auxiliary - wheel assembly 50 on the push rod 30, and the relative position between the auxiliary - wheel fixing member 54 and the second fixing sleeve 52 can be adjusted through the kidney - shaped hole 541 to adjust the up - and - down position of the auxiliary wheel 51.

[0035] AsFigure 6 As shown, when cutting the ornament 60, the left end thereof is placed in the groove 101 and locked with the first fixing member 12, so that the relative position of the ornament 60 and the track push knife can be better controlled, making the cutting more accurate.

[0036] During cutting, the cutting wheel 41 at the bottom of the push knife assembly 40 can be adjusted to be slightly higher than the auxiliary wheel 51 at the bottom of the auxiliary wheel assembly 50. When the push rod 30 is pressed to make the cutting wheel 41 and the auxiliary wheel 51 roll on the surface of the ornament 60, the auxiliary wheel 51 can undergo elastic deformation so that the cutting wheel 41 contacts the surface of the ornament 60, thereby realizing the cutting function normally.

[0037] When the cutter wheel 41 slides to the end on the decoration 60 and is about to lose contact with the decoration 60, due to inertia, the cutter wheel 41 and the auxiliary wheel 51 will tend to continue to move downward. At this time, the auxiliary wheel 51 will restore its original shape and first contact with the ground where the decoration 60 is placed, thereby playing a buffering role, reducing the collision between the cutter wheel 41 and the ground, and protecting the cutter wheel 41.

[0038] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
