Description

Technical Field

[0001] This utility model belongs to the field of embossing technology, and in particular relates to an assembled handheld embossing device. Background Technology

[0002] During concrete road construction, to prevent slippage and accidents caused by wet surfaces, the concrete pavement is often textured to increase ground resistance and ensure the safety of pedestrians and vehicles. This is typically done manually by using a push-and-pull roller to create wheel tracks.

[0003] Traditional embossing tools use simple wire toothed rakes to create patterns on the road surface. This method results in uneven and non-straight patterns. Later, a roller-type embossing tool was designed, which mainly consists of an embossing roller and a handle for pushing and pulling the roller. It is manually pulled and rolled laterally across the not-fully-cured road surface to create the corresponding patterns. It is low-cost and easy to carry and store.

[0004] For example, Chinese utility model patent with patent publication number CN217579685U and publication date of October 14, 2022, discloses a novel floor embossing device. The structure includes a fixed tube sleeve seat and a concave shell. The fixed tube sleeve seat is installed and fixed at the middle position of the upper end of the concave shell. An outer concave rod is provided on the outer side of the fixed tube sleeve seat on the concave shell. A metal round rod is provided on the inner side of the outer end of the fixed tube sleeve seat. An upper handle is provided on the outer end of the metal round rod. A rotating roller is provided in the middle of the inner side of the concave shell. A limit bearing is provided at the connection between the concave shell and the rotating roller. Several embossing teeth are provided on the periphery of the rotating roller.

[0005] The general structural principle of the floor embossing device in this utility model patent is as follows: When in use, the operator holds the outer concave rods on both sides of the upper end of the concave housing, making it easy to hold and lift, and easy to place in the designated position. During embossing, the upper handle of the metal rod makes it easy to hold and push. The upper handle drives the concave housing to move. The concave housing and the rotating roller are fixed by the limiting bearing, so the concave housing can rotate on the outside of the rotating roller, making it easy to push for embossing. During the rotation of the rotating roller, the embossing teeth on the periphery of the rotating roller facilitate embossing. The embossing teeth are equipped with a toothed cleaner on the periphery, so the embossing teeth can clean the attached objects when rolling.

[0006] However, in actual use, this floor embossing device still has at least the following two shortcomings, which are the technical problems that this utility model aims to solve.

[0007] 1. Its metal rod structure is fixed at both ends with screws, thus lacking a practical grip length adjustment function.

[0008] 2. Its direct embossing structure, consisting of embossing teeth and rotating rollers, suffers from the problem that the effective embossing width is not adjustable, resulting in relatively poor practicality.

[0009] Therefore, in summary, there is an urgent need for a new type of handheld embossing device that is easy to assemble and disassemble and highly practical. Utility Model Content

[0030] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0031] As attached Figure 1-6 As shown, an assembled handheld embossing device includes a gripping screw unit 1 and a mounting plate unit 2, an internally threaded cylinder 3 disposed on the mounting plate unit 2 and used to screw the gripping screw unit 1, a pressure rod unit 4 inserted on the mounting plate unit 2, and a plurality of embossing ring units 5 sleeved on the pressure rod unit 4 and used to adjust the embossing width.

[0032] In this embodiment, one end of the gripping screw unit 1 is screwed to the internally threaded cylinder 3, and the other end is provided with a rubber sleeve for easy gripping by the user; the mounting plate unit 2 is provided with the internally threaded cylinder 3, and the other end is provided with the mounting rod unit 4. The mounting plate unit 2 can be a rod-mounted structure or a plate-mounted structure. The internally threaded cylinder 3 is welded or integrally fixed on the mounting plate unit 2, and the mounting rod unit 4 is inserted into the mounting plate unit 2, thereby making the gripping screw unit 1, the mounting plate unit 2, and the mounting rod unit 4 detachable, easy to assemble and disassemble, and convenient for transportation and use.

[0033] Furthermore, the gripping screw unit 1 is screwed to the internal threaded cylinder 3, thereby allowing the extension length of the gripping screw unit 1 to be selected to adapt to different length requirements of the gripping screw unit 1, thus reducing the limitations of its use in various scenarios.

[0034] Finally, the embossing ring units 5 are spaced apart on the pressure rod unit 4. The embossing ring units 5 can be fastened to the pressure rod unit 4 by snapping, or by welding, bonding, or other methods, so that the number of embossing ring units 5 can be increased or decreased, thereby adjusting the number and width of the embossing.

[0035] The gripping screw unit 1 includes a gripping rod 101, a threaded rod 102 disposed on the gripping rod 101, and a fastening nut 103 disposed on the threaded rod 102 and used to clamp the internally threaded cylinder 3.

[0036] In this embodiment, one end of the gripping rod 101 is provided with a threaded rod 102 that is connected to the internally threaded cylinder 3. The fastening nut 103 is provided on the threaded rod 102 exposed outside the internally threaded cylinder 3. The threaded rod 102 is connected by the fastening nut 103, which not only ensures the firmness of the gripping rod 101 and the internally threaded cylinder 3, but also allows the gripping rod 101 to freely extend and retract without falling off.

[0037] The mounting plate unit 2 includes a mounting plate 201 with the internally threaded cylinder 3, and two U-shaped side plates 202 disposed on the mounting plate 201 for mounting the pressure bar unit 4.

[0038] In this embodiment, the mounting plate 201 can be a rod or a plate to ensure that it can be stably connected to the internally threaded cylinder 3 and the two U-shaped side plates 202. The U-shaped side plates 202 are used to install the pressure rod unit 4. The pressure rod unit 4 is inserted into the groove of the U-shaped side plate 202. The connection between the pressure rod unit 4 and the U-shaped side plate 202 can be ensured by increasing friction or adhesion.

[0039] The pressure bar unit 4 includes a crossbar 401 disposed on the U-shaped side plate 202.

[0040] In this embodiment, the crossbar 401 is held by two U-shaped side plates 202, and the length of the crossbar 401 is longer than the distance between the two U-shaped side plates 202.

[0041] The embossing ring unit 5 includes an embossing ring 501 sleeved on the crossbar 401, and an assembly / disassembly opening 502 provided on the embossing ring 501.

[0042] In this embodiment, the embossing ring 501 can be made of steel reinforcement or other materials with a certain strength. The disassembly opening 502 is provided on the embossing ring 501. By prying open the disassembly opening 502, the embossing ring 501 can be fitted onto the crossbar 401. Further clamping the disassembly opening 502 fixes the embossing ring 501 to the crossbar 401, thereby performing the embossing operation. The embossing ring 501 is not only readily available but also easy to replace. For different road widths requiring embossing, simply add or remove the embossing ring 501, making it flexible and practical. The embossing ring 501 protrudes from the U-shaped side plate 202, thereby achieving the embossing effect.

[0043] The mounting plate unit 2 also includes a mating hole 203 disposed on the U-shaped side plate 202, and a limiting screw 204 disposed on the mating hole 203 and used to lock the pressure rod unit 4.

[0044] In this embodiment, the hole 203 is used to insert the limiting screw 204, which is used to limit and support the embossing unit 4, preventing the embossing unit 4 from falling off. Furthermore, the limiting screw 204 can lock the embossing unit 4 in the U-shaped side plate 202, preventing it from rotating. Alternatively, by adjusting the tightness of the connection between the limiting screw 204 and the embossing unit 4, the embossing unit 4 can roll within the U-shaped side plate 202, thereby driving the embossing ring unit 5 to roll and emboss.

[0045] The mounting plate unit 2 also includes a locking nut 205 disposed on the limiting screw 204.

[0046] In this embodiment, the locking nut 205 is used to further strengthen the screwing strength of the limiting screw 204, and at the same time facilitates the disassembly and replacement of the embossing unit 4.

[0047] The pressure bar unit 4 also includes a thickened ring 402 disposed on the crossbar 401, and an annular groove 403 disposed on the pressure bar unit 4 and used to fix the embossing ring 501.

[0048] In this embodiment, the thickening ring 402 is disposed on the crossbar 401 as a positioning block for the embossing ring 501, ensuring the connection stability of the embossing ring 501. The thickening ring 402 is farther from the road surface than the U-shaped side plate 202, thus not affecting the embossing effect. The annular groove 403 is used to install the embossing ring 501, making installation more convenient, faster, and more secure.

[0049] The mounting plate unit 2 further includes two sets of idle ring mounting slots 206 respectively disposed on two sides of the mounting plate 201 and used to insert and install the two ends of the opening of the removed embossing ring 501.

[0050] In this embodiment, the idle ring placement slot 206 serves to prevent the loss of embossing rings 501 when the number of embossing rings 501 on the pressure rod unit 4 decreases. The removed embossing rings 501 can be placed in the idle ring placement slot 206. Alternatively, embossing rings 501 can be placed in advance for backup, facilitating replacement and reducing downtime. Preferably, the mounting plate 201 is a round rod.

[0051] The pressure bar unit 4 also includes a mounting hole 404 disposed on the crossbar 401 and used for inserting the limiting screw 204.

[0052] In this embodiment, the mounting hole 404 is used to insert the limiting screw 204, so that the crossbar 401 is fixedly mounted on the U-shaped side plate 202 and the crossbar 401 cannot rotate. Different fixing requirements can be met by setting several sets of mounting holes 404, but not too many, as this may affect the structural strength of the crossbar 401.

[0053] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model.
