DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1 A typical implementation of the present invention is as follows Figure 1As shown, a bus floor leather welding rod flattening device includes a main body rod 1, one end of the main body rod 1 is provided with a cutting assembly 3, the cutting assembly 3 is detachably connected to the main body rod 1, and the welding rod is flattened by using the cutting assembly 3, and the other end of the main body rod 1 is fixed with a hand support assembly, and the hand support assembly is provided with an adjustment assembly, which can adjust its own length to meet different usage requirements.

[0022] One end of the main rod 1 that fixes the cutting assembly 3 is the flattening end 101. The flattening end 101 is a flat structure with flat top and bottom. The flattening end 101 extends obliquely upward and forms a set angle with the main rod 1. The cutting assembly 3 is fixed on the bottom surface of the flattening end 101. By setting the flattening end 101, the cutting assembly 3 can be pressed down to keep it close to the welding rod, making it convenient to cut the welding rod.

[0023] like Figure 4 As shown, the cutting assembly 3 includes a connecting plate 301, one end of the connecting plate 301 is a cutting end, and the other end is a fixed end. A groove 303 is opened in the middle of the fixed end, and positioning holes 302 are arranged on both sides of the groove 303. A bolt hole is opened in the middle of the bottom surface of the flattening end 101, and the bolt hole is arranged corresponding to the groove 303. Positioning blocks are arranged on both sides of the bolt hole, and the positioning blocks are arranged corresponding to the positioning holes 302. When installing, the two positioning holes 302 are respectively sleeved on the outside of the two positioning blocks. At this time, the groove 3 03 is arranged opposite to the bolt hole, a fixing bolt 4 is arranged in the bolt hole, an extrusion plate 401 is arranged at the bottom end of the fixing bolt 4, the diameter of the extrusion plate 401 is larger than the width of the groove 303, the connecting plate 301 is located between the flattening end 101 and the extrusion plate 401, and the fixing bolt 4 is tightened to squeeze the connecting plate 301 through the extrusion plate 401, so that the connecting plate 301 is fixed on the main rod 1, and the cooperation between the positioning hole 302 and the positioning block ensures the stability of the installation of the connecting plate 301.

[0024] The bottom surface of the squeezing disc 401 is a plane. When cutting, the bottom surface of the squeezing disc 401 contacts the surface of the floor leather, supporting the flattening device and reducing the friction between the floor leather and the flattening device when pushing the flattening device.

[0025] The width of the cutting end is greater than the width of the connecting end, thereby providing a larger force-bearing area during cutting. An arc-shaped cutting edge 304 is provided in the middle of the cutting end. The width of the arc-shaped cutting edge 304 is adapted to the width of the welding rod. A cutting blade is provided on the inner side of the arc-shaped cutting edge 304, and the welding rod is flattened by the cutting blade. By providing the arc-shaped cutting edge 304 and the cutting blade on the inner side of the arc-shaped cutting edge 304, only the protruding welding rod is cut during cutting, and the floor leather on both sides of the welding rod will not be damaged, thereby improving the cutting efficiency of the welding rod.

[0026] When in use, first align the arc-shaped blade 304 with the welding rod so that the welding rod to be cut is located in the arc-shaped blade 304, and the bottom surface of the extrusion plate 401 is in contact with the surface of the floor leather. Since the flattening end 101 and the main rod 1 are at a set angle, it is convenient to push the main rod 1. When pushing the main rod 1, the flattening end 101 can also be pressed to ensure the flatness of the cutting surface of the welding rod.

[0027] The present invention arranges the cutting assembly 3 at the bottom of the flattening end 101. After the positioning hole 302 and the positioning block are spliced, the fixing bolt 4 can be installed on the inner side of the flattening end 101 using the extrusion plate 401, thereby realizing the rapid installation of the cutting assembly 3. At the same time, different cutting assemblies 3 can be replaced according to different welding rods, and the cutting assembly 3 can be replaced at any time when it is damaged, thereby improving the convenience of cutting the welding rod.

[0028] like Figure 2 and Figure 3 As shown, the hand support assembly includes a support column 102, which is perpendicular to the main rod 1, and one end of the main rod 1 away from the flattening end 101 is fixedly connected to the middle of the support column 102. The support column 102 and the main rod 1 are in a T-shaped structure, and adjustment components are arranged at both ends of the support column 102. The adjustment component includes a limit sleeve 103, and the limit sleeve 103 is a cylindrical structure. The limit sleeve 103 is opened at one end away from the support column 102, and a movable column 203 is arranged in the limit sleeve 103. The diameter of the movable column 203 is smaller than the inner diameter of the limit sleeve 103, and the movable column 203 is movably connected to the limit sleeve 103. The movable column 203 can move along the axial direction of the limit sleeve 103 and can rotate around the axis of the limit sleeve 103, so that the length of the entire hand support assembly can be adjusted by moving the movable column 203, so that it can adapt to different usage requirements.

[0029] A limiting disk 204 is provided at one end of the movable column 203, and the diameter of the limiting disk 204 is equal to the inner diameter of the limiting sleeve 103. A limiting protrusion 104 is provided at the open end of the limiting sleeve 103. The limiting protrusion 104 is a circular ring structure, and the inner diameter of the limiting protrusion 104 is the same as the diameter of the movable column 203. By providing the limiting disk 204 and the limiting protrusion 104, the movement of the movable column 203 is limited to prevent the movable column 203 from falling off from the limiting sleeve 103.

[0030] A connecting block 2 is provided at one end of the movable column 203 away from the limiting plate 204. The connecting block 2 is cylindrical, and the axis of the connecting block 2 coincides with the axis of the movable column 203. An arc plate 201 is provided on the outside of the movable column 203. The curvature of the arc plate 201 is the same as the curvature of the outer surface of the limiting sleeve 103. The arc plate 201 and the movable column 203 are spaced apart by a set distance. One end of the arc plate 201 is fixed at the outer edge of the bottom surface of the connecting block 2. A plurality of arc strips 202 are provided on one side of the arc plate 201. The curvature of the arc strip 202 is the same as that of the arc plate 201, and the curvatures of the arc strip 202 and the arc plate 201 are both 1 / 4 circle. The plurality of arc strips 202 are arranged side by side along the length direction of the arc plate 201, and a set distance is spaced apart between two adjacent arc strips 202.

[0031] An arc-shaped protrusion is provided on the outer surface of the limiting sleeve 103, and a plurality of arc-shaped grooves 105 are opened on one side of the arc-shaped protrusion. The plurality of arc-shaped grooves 105 are arranged side by side along the length direction of the arc-shaped protrusion. The curvature of the arc-shaped protrusion and the arc-shaped groove 105 are both 1 / 4 circle. The arc plate 201 and the arc-shaped bar 202 are both located outside the limiting sleeve 103. The plurality of arc-shaped grooves 105 are adapted to the plurality of arc-shaped bars 202, so that the arc-shaped bars 202 can be inserted into the arc-shaped grooves 105.

[0032] By setting the arc groove 105 and the arc bar 202, the position of the movable column 203 can be fixed. When the movable column 203 moves to a suitable position, the arc bar 202 is inserted into the arc groove 105. At this time, the movable column 203 can no longer move, thereby fixing the length of the entire hand support assembly and preventing the movable column 203 from sliding and affecting normal use.

[0033] When in use, first rotate the connecting block 2 to disengage the arc strip 202 from the arc groove 105, and then pull the movable column 203 outward to adjust the length of the entire hand support assembly. When the length meets the use requirements, rotate the connecting block 2 in the opposite direction to reinsert the arc strip 202 into the arc groove 105, and move the limiting movable column 203 so that the length of the hand support assembly can meet the use requirements.

[0034] The present invention sets a limit sleeve 103 and a movable column 203. The movable column 203 inside the limit sleeve 103 can slide outward laterally. After the outward extension, the arc strip 202 is kept corresponding to the arc groove 105. The movable column 203 can be restricted by rotating the movable column 203 in the opposite direction, thereby preventing the movable column 203 from moving inside the limit sleeve 103. After the arc strip 202 is flipped and inserted, the friction force can be used to avoid the problem of looseness. The length of the hand support component can be adjusted by using the adjustment component to meet different needs.

[0035] Embodiment 2 This embodiment provides a method for flattening a welding rod for a passenger car floor covering, using a passenger car floor covering welding rod flattening device as described in the first embodiment, comprising the following steps: When in use, first pull the movable column outward according to demand, and adjust the movable column outward along the limit groove. After adjustment, control the arc plate to rotate ninety degrees along the outside of the limit sleeve. During the rotation, the arc bar is inserted into the corresponding arc groove to limit the movable column, thereby fixing the length of the hand support assembly to meet different usage requirements and prevent the movable column from moving during cutting, affecting normal cutting. Then place the connecting plate at the bottom of the flattening end, use the positioning groove and the positioning block to limit the connecting plate, connect the fixing bolt to the flattening end, and use the extrusion plate to squeeze and fix the connecting plate. Finally, grasp the hand support assembly, align the arc blade with the welding rod, and use the cutting blade to flatten the protruding excess welding rod.

[0036] The present invention can accurately cut the welding rod without damaging the floor leather on both sides of the welding rod. At the same time, different cutting components can be replaced according to different welding rods, and the cutting component can be replaced at any time when it is damaged, thereby improving the convenience of cutting the welding rod.
