DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0027] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0028] This embodiment mainly describes a paving machine that is easy to operate, as follows:

[0029] like Figures 1 to 7As shown, a paving machine which is easy to operate includes a shell 1, a vibration seat 2 and a suction cup 3. The shell 1 has a mounting cavity 4. The vibration seat 2 is arranged at the bottom of the shell 1 and located at the opening of the mounting cavity 4. The suction cup 3 is arranged below the vibration seat 2. A vibration assembly 6 fixed on the vibration seat 2 is arranged in the mounting cavity 4. The vibration assembly 6 is used to provide a vibration power source for the vibration seat 2. A pull rod assembly 7 rotatably connected to the vibration seat 2 is arranged in the mounting cavity 4. The suction cup 3 has a column 711 that passes through the vibration seat 2 and is connected to the pull rod assembly 7. The shell 1 has a hand-held portion 11. The shell 1 has a mounting port 13 that connects the mounting cavity 4 with the outside. The pull rod assembly 7 has an extension section that extends from the mounting cavity 4 through the mounting port 13 to the outside of the shell 1 and is located below the hand-held portion 11, and the portion of the extension section located at the mounting port 13 can move upward or downward in the mounting port 13. The extension section is hinged with a hook body 8, specifically, the middle part of the extension section is provided with a mounting hole 731, the hook body 8 is arranged in the mounting hole 731 and is hinged with the inner wall of the mounting hole 731. The hand-held part 11 is provided with a limiting part 9 for fixing the hook body 8. When the extension section is pressed to approach the hand-held part 11, the pull rod assembly 7 rotates upward around the rotation connection point between it and the vibration seat 2, thereby driving the suction cup 3 to suck up the ceramic tile or floor tile, and the hook body 8 is rotated so that the hook body 8 is hooked on the limiting part 9 to limit the pull rod assembly 7. When the suction cup 3 stops working, the hook body 8 is rotated so that the hook body 8 is separated from the limiting part 9, and the pull rod assembly 7 rotates downward around the rotation connection point between it and the vibration seat 2, and the suction cup 3 returns to the initial position downward. Pressing the extension section and limiting or unlocking the pull rod assembly 7 can be performed at the same time, which is simple and convenient to operate, and there is no need to specially cover the hook on the pull rod assembly 7. During use, the pull rod assembly 7 is not easy to slide out, and the safety is high.

[0030] like Figures 4 to 7As shown, the pull rod assembly 7 includes a connecting seat 71, a connecting arm 72 and an operating rod 73. The connecting arm 72 is hinged to the connecting seat 71. Specifically, the connecting seat 71 has two inverted U-shaped arms 714 arranged at intervals. The two inverted U-shaped arms 714 are provided with hinge holes. The connecting arm 72 is arranged between the two inverted U-shaped arms 714. The connecting arm 72 is hinged to the two U-shaped arms through a hinge shaft 721 and the hinge hole. One end of the operating rod 73 extends out of the housing 1 to the bottom of the handheld portion 11, and the other end is connected to the connecting arm 72. Fixed connection, the extension section is the part of the operating rod 73 located outside the housing 1, and the end of the connecting arm 72 away from the operating rod 73 is hinged with the vibration seat 2. Specifically, the vibration seat 2 has two support columns 26 arranged at intervals, and the end of the connecting arm 72 away from the operating rod 73 is rotatably provided with a rotation shaft 713, and the two ends of the rotation shaft 713 are respectively rotatably connected with the two support columns 26, and the height of the connection point between the connecting arm 72 and the two support arms is higher than the height of the rotation point between the connecting arm 72 and the operating rod 73. By rotating the end of the connecting arm 72 away from the operating rod 73 and the vibration seat 2, a lever principle is formed, and the total length of the operating rod 73 and the connecting arm 72 is the longest. The lever principle and the design of the inverted U-shaped arm 714 effectively enhance the suction force of the suction cup. When the operating rod 73 and the connecting arm 72 rotate around the connection point between the connecting arm 72 and the two support arms, only a little force is needed to drive the operating rod 73 and the connecting arm 72 to rotate, and the suction cup is sucked up, which is relatively labor-saving as a whole. The height of the connection point between the connecting arm 72 and the two support arms is designed to be higher than the height of the rotation point between the connecting arm 72 and the operating rod 73, which can provide sufficient rotation space for the connecting arm 72. While ensuring the normal rotation of the connecting arm 72, the overall structure is compact and the space utilization rate of the installation cavity 4 is improved.

[0031] Specifically, the column 711 on the suction cup 3 passes through the vibration base 2 and is connected to the bottom of the vibration base 2. Specifically, the vibration base 2 has a through hole 22, and a threaded hole is provided along the length direction at one end of the column 71 close to the connecting base 71. The connecting base 71 is provided with a connecting hole corresponding to the position of the through hole 22. The column 711 penetrates into the through hole 22, and the screws pass through the connecting hole and the through hole 22 in turn and extend into the column 711 to fix the column 711 and the connecting base 71 through threaded cooperation. When the connecting arm 72 drives the suction cup 3 to be lifted or reset, the column 711 slides up and down in the through hole 22. To avoid interference between the suction cup 3 and the column 711 during the upward sliding process, a gap is provided between the inner wall of the through hole 22 and the outer wall of the column 711. When the operating lever 73 is pressed and rotated toward the hand-held portion 11, the operating lever 73 drives the connecting arm 72 to rotate upward around the rotation point between the connecting arm 72 and the vibration seat 2. The connecting arm 72 drives the connecting seat 71 to rotate upward during the rotation process. During the upward rotation process of the connecting seat 71, the column 711 slides up and down on the vibration seat 2. In order to effectively improve the uniformity and firmness of the suction force of the suction cup 3, the suction cup 3 3 is a rubber disc, with at least two columns 711. One end of the plurality of columns 711 away from the connecting seat 71 is fixedly connected to the limiting disc 10. The lower ends of the limiting disc 10 and the columns 711 are wrapped inside the suction cup 3. When the connecting seat 71 is lifted upward, the columns 711 are driven to lift the suction cup upward to generate suction on the ceramic tile or floor tile. The center of the limiting disc 10 and the suction cup 3 are on the same axis. When the suction cup 3 and the connecting seat 71 are installed, the columns 711 are installed on the suction cup 3 in a circular array with the center of the suction cup 3 and the limiting disc as the center.

[0032] like Figure 7 As shown, the two inverted U-shaped arms 714 and the vibration seat 2 form a U-shaped avoidance hole 712, and the vibration assembly 6 is located in the U-shaped avoidance hole 712. The vibration assembly 6 is arranged in the U-shaped avoidance hole 712, which can save installation space and make the overall structure of the paving machine compact and beautiful. In order to avoid interference during the rotation of the connecting arm 72 relative to the connecting seat 71, the connecting arm 72 matches the shape of the inverted U-shaped arm 714 and is an inverted U shape.

[0033] Specifically, the vibration seat 2 is circular, and the vibration component is located in the middle of the vibration seat. Specifically, the vibration component 6 includes a motor 61 and an eccentric wheel 62 arranged on the output shaft of the motor 61. A mounting groove 21 for mounting the motor 61 and adapted to the shape of the motor is provided in the middle of the vibration seat 2. A working groove 23 is provided at the outer end of the mounting groove 21, which contacts the eccentric wheel 62 to generate vibration when the eccentric wheel 62 is working. The motor 61 is installed in the mounting groove 21, and the eccentric wheel 62 is installed in the working groove. After the motor 61 is installed on the vibration seat 2, the motor 61 is located in the center of the vibration seat 2. This design has the following advantages: During the use of the paving machine, not only the uniformity of the vibration of the vibration seat 2 on the ceramic tiles or floor tiles is improved, but also the vibration sensation of the handheld part 11 can be reduced, thereby enhancing the user experience. A fixing sleeve 63 is sleeved on the outer wall of the motor 61. The fixing sleeve 63 is an arc shape that matches the outer wall of the motor 61. Fixing holes 64 are provided on both sides of the fixing sleeve 63. Threaded holes corresponding to the positions of the fixing holes 64 are provided on the vibration seat 2. The screws pass through the fixing holes 64 and are threadedly connected to the vibration seat 2. There is a gap between the bottom of the nut and the fixing hole 64. When the eccentric wheel 62 is working, the fixing sleeve 63 slides up and down on the screw to extend the service life of the vibration seat 2. In order to prevent the vibration seat 2 from being separated from the housing 1 during the operation of the vibration assembly 6, a connecting ring 24 is provided on the vibration seat 2. Figure 2 As shown, the housing 1 includes a left housing 14 and a right housing 15, and the left housing 14 and the right housing 15 are plugged into each other to form the housing 1. Figure 4 As shown, the inner walls of the left shell 14 and the right shell 15 are both provided with a plug 16, the insertion rod on the left shell 14 extends into the connecting ring 24 and is plugged into the plug 16 on the right shell 15, and a shock-absorbing ring 25 is provided on the inner wall of the connecting ring 24, and the plug 16 and the shock-absorbing ring 25 are interference fit. The design of the shock-absorbing ring 25 can effectively reduce the vibration frequency of the wrist during the use of the paving machine, making the user feel more comfortable.

[0034] like Figure 3 and Figure 4 As shown, the limiting portion 9 is a fixed column with both ends fixed to the inner wall of the hand-held portion 11, or a limiting groove arranged inside the hand-held portion 11. A through hole 12 for the hook body 8 to pass through is opened on the shell 1 at the hand-held portion 11. One end of the hook body 8 passes through the through hole 12 and is installed in the shell 1. When the extension section of the hand-held portion 11 is driven to approach the hand-held portion 11, the hook body 8 is rotated to hook on the fixed column to limit the pull rod assembly 7.
