Fig. 1 is a perspective view showing a recess restoration device 100 according to an embodiment of the present invention. Fig. 2 is a sectional view showing the recess repairing apparatus 100 shown in fig. 1 along the line II-II. As shown in fig. 1 and 2, the recess restoration device 100 includes a pulling mechanism, a slider 60, and a connector 80. The drawing mechanism in the present embodiment includes a main body 10, two leg plates 20, a fixed handle 30, a movable handle 40, and a pull rod 50.

The two foot plates 20 are movably connected with the main body 10 respectively. The fixed handle 30 is fixedly connected with the main body part 10, and the movable handle 40 is movably connected with the main body part 10. The pull rod 50 penetrates the main body 10, the fixed handle 30, and the movable handle 40.

Specifically, each foot board 20 includes a flat plate portion 21, two support portions 22, and a slide portion 23. The flat plate portion 21 is substantially plate-shaped, and the two support portions 22 are provided so as to protrude from the flat plate portion 21 and so as to be spaced apart from each other. The sliding part 23 is movably inserted into the movable groove 102 of the main body 10 and is mounted on the two support parts 22. One end of the sliding portion 23 is fixedly connected to one support portion 22, and the other end is fixedly connected to the other support portion 22.

The main body 10 is substantially in the form of an axially symmetric plate and includes two protrusions 12. The end of each protrusion 12 is located between two support portions 22 of one of the foot plates 20, and a sliding portion 23 is movably inserted through the end of the protrusion 12. The two protrusions 12 are symmetrically arranged with the axis of symmetry of the main body 10 as an axis. The end of each protrusion 12 is provided with the movable groove 102.

More specifically, one end of the fixed handle 30 is fixed to a side of the main body 10 away from the two foot boards 20. One end of the movable handle 40 is inserted into the main body 10 and is hinged to the middle of the main body 10. The fixed handle 30 and the movable handle 40 have a length suitable for being grasped by a hand of a person, and when the palm of the person abuts against one end of the fixed handle 30 and grasps one end of the movable handle 40, the movable handle 40 rotates toward the fixed handle 30 with the position hinged to the main body portion 10 as a rotation center.

As shown in fig. 2, the tie rod 50 includes a screw portion 51, a nut portion 52, and a sleeve 53. The nut portion 52 is threadedly coupled to an end of the screw portion 51 remote from the foot plate 20 (i.e., an end close to the fixed handle 30). The sleeve 53 is sleeved on the screw part 51. The screw portion 51 penetrates the main body 10, the fixed handle 30, and the movable handle 40. One end of the nut 52 abuts against the end of the main body 10 to which the fixed handle 30 is attached. The sleeve 53 is inserted into the main body 10 and the fixed handle 30. The end of the sleeve 53 remote from the nut portion 52 abuts against the movable handle 40. When the movable handle 40 rotates towards the fixed handle 30 with the position hinged to the body 10 as the rotation center, the sleeve 53 is driven to move in the direction protruding out of the body 10, the sleeve 53 drives the screw part 52 to move in the direction protruding out of the body 10, so that the screw part 53 drives the screw part 51 to move in the direction protruding out of the body 10.

Further, the recess restoration device 100 further includes a slider 60 and an elastic member 70. The slider 60 is connected to an end of the screw portion 51 remote from the nut portion 52.

The head 62 is located outside the body 10 and between the two protrusions 12. The elastic element 70 is sleeved on the rod-shaped portion 61, and one end of the elastic element abuts against the main body portion 10, and the other end abuts against the head-shaped portion 62.

As described above, when the movable handle 40 rotates towards the fixed handle 30 about the position hinged to the main body 10, the sleeve 53 is driven to move in the direction protruding from the main body 10, the screw portion 51 moves in the direction protruding from the main body 10, so that the screw portion 51 drives the slider 60 to move in the direction of inserting into the main body 10, and the elastic member 70 contracts (i.e. kinetic energy is converted into potential energy). On the other hand, when the movable handle 40 is not stressed, the elastic potential energy of the elastic element 70 provides the kinetic energy for the pull rod 50 and the pull head 60 to restore the initial positions, so that the pull rod 50 and the pull head 60 move to the initial positions in the opposite directions.

Further, the head portion 62 of the slider 60 is engaged with the coupling head 80 shown in fig. 8. As shown in fig. 8 (a), the connection head 80 includes a mounting portion 81, an adsorption portion 82, and an intermediate portion 83. One end of the intermediate portion 83 is connected to the mounting portion 81, and the other end is connected to the suction portion 82. In the present embodiment, the mounting portion 81 has a cylindrical shape with a single round protrusion outside, but is not limited thereto as long as it can engage with the head portion 62. The adsorption portion 82 is provided with a plurality of adsorption grooves for adsorption onto an automobile body to be repaired. In the present embodiment, the adsorption part 82 has an oval shape and four rows of adsorption grooves are provided, but the present invention is not limited thereto, and the adsorption part 82 may have an oval shape and two rows of adsorption grooves are provided as shown in fig. 8 (b). Further, as shown in fig. 8 (b), the suction portion 82 may have a circular shape and may be provided with three layers of suction grooves radially arranged. Further, as shown in fig. 8 (d), the suction portion 82 may have a circular shape and may be provided with two layers of suction grooves arranged radially. Further, as shown in fig. 8 (e), the suction portion 82 may have a circular shape and may be provided with two layers of suction grooves arranged radially, but the size may be smaller than the suction portion 82 shown in fig. 8 (d). Therefore, the shape of the suction portion 82 and the arrangement of the suction grooves thereon can be adjusted according to actual needs.

When the depression repairing apparatus 100 is used, the two foot plates 20 of the depression repairing apparatus 100 are placed on the two sides of the depression, and the connector 80 is fixed at the position of the depression; the palm of the hand abuts against one end of the fixed handle 30 and grasps one end of the movable handle 40, so that the movable handle 40 rotates towards the fixed handle 30 with the position hinged to the main body 10 as the rotation center, the sleeve 53 drives the screw part 52 to move in the direction protruding out of the main body 10, the screw part 53 drives the screw part 51 to move in the direction protruding out of the main body 10, the screw part 51 drives the slider 60 to move in the direction of inserting into the main body 10, the elastic element 70 contracts, and the connector 80 moves in the direction of facing the main body 10, so that the recess is pulled in the reciprocating direction until the recess is restored. Therefore, the repair of the automobile recess by the recess repair device 100 has no damage to the automobile sheet metal and the repair efficiency is fast.

As shown in fig. 3 and 4, the rod portion 61 is opened with a through hole 601. The head 62 is generally cylindrical and includes a top wall 621, a bottom wall 622, and a side wall 623. The top wall 621 is disposed opposite to the bottom wall 622, and one end of the side wall 623 is connected to the top wall 621 and the other end is connected to the bottom wall 622. The side wall 623 and the bottom wall 622 of the head 62 are provided with engaging grooves 602. The area of the engaging groove 602 is defined by the top wall 621, the bottom wall 622 and the side wall 623. The engaging groove 602 communicates with the through hole 601. The side wall 623 is provided with a side opening 603, and the side opening 603 communicates with the engagement groove 602. The bottom wall 622 has a bottom opening 604 formed therethrough, and the bottom opening 604 communicates with the engagement groove 602 and also communicates with the side opening 603. Therefore, the attachment portion 81 of the connection head 80 is caught in the engagement groove 602 via the side opening 603 and the bottom opening 604, and the suction portion 82 of the connection head 80 is positioned directly below the slider 60. When the slider 60 and the connecting head 80 are assembled, the mounting portion of the connecting head 80 is fitted into the engaging groove 602, and the suction portion 82 of the connecting head 80 is located below the engaging groove 602, so that the connecting head 80 is coaxially connected to the slider 60. In the present embodiment, the side opening 603 is substantially rectangular, and the bottom opening 604 is U-shaped.

The bottom surface of the engagement groove 602 has a stepped structure with a vertical structure, and the connector 80, not shown, is engaged in the engagement groove 602 and is prevented from coming out of the engagement groove 602 by the stepped structure. A flat surface 6021, two curved inclined surfaces 6023, and two stopper surfaces 6025 are formed on the groove bottom surface of the engagement groove 602 in this order. The flat face 6021 is generally a semi-circular ring structure and is disposed around the bottom opening 604. Two inclined faces 6023 are formed extending obliquely upward from both ends of the flat face 6021, respectively, and two barrier faces 6025 are formed extending outward from one ends of the two inclined faces 6023 remote from the flat face 6021. There is a height difference between the barrier face 6025 and the flat face 6021, with the barrier face 6025 being above the flat face 6021. Therefore, when the mounting portion 81 of the connecting head 80 comes into contact with the flat surface 6021 and the two inclined surfaces 6023 when the connecting head 80 is mounted in the engagement groove 602, and the mounting portion 81 of the connecting head 80 moves toward the two inclined surfaces 6023 and the two stopper surfaces 6025 due to the presence of the two inclined surfaces 6023 and the two stopper surfaces 6025, the movement of the mounting portion 81 of the connecting head 80 is stopped by the two inclined surfaces 6023 and the two stopper surfaces 6025, and the mounting portion 81 of the connecting head 80 is prevented from coming out of the engagement groove 602, thereby preventing the connecting head 80 from coming out of the engagement groove 602 during the repair work.

In addition, since the mounting portion 81 of the connector 80 is formed with the ridge, a friction force is increased between the mounting portion 81 of the connector 80 and the two inclined surfaces 6023, and the connector 80 is further effectively prevented from coming off from the engagement groove 602 during the repair work. The inclined surface 6023 may be a curved surface (i.e., the inclined surface 6023 is curved), and the structure of the inclined surface 6023 may be designed according to actual needs.

Referring to fig. 2 again, one end of the screw 51 away from the screw 52 is located in the engaging groove 602 and abuts against the top wall 621. Therefore, the screw portion 51 can move the slider 60 in the direction of inserting into the body 10. Specifically, when the pull rod 50 is attached, the screw portion 51 is inserted into the engagement groove 602 from the side opening 603 and the bottom opening 604, inserted into the through hole 601, inserted into the movable handle 40, inserted into the sleeve 53, and screwed into the nut portion 52.

Further, the side of the bottom wall 622 closer to the side opening 603 is higher than the side farther from the side opening 603. That is, the side of the bottom wall 622 close to the side opening 603 is located at a shorter distance from the top wall 621 than the side of the bottom wall 622 remote from the side opening 603.

In one embodiment, as shown in fig. 3 and 4, the height of the bottom wall 622 changes to a gradually sloping shape from the side close to the side opening 603 to the side away from the side opening 603. In another embodiment, as shown in fig. 5 and 6, the height of the bottom wall 622 changes to an abrupt step from the side close to the side opening 603 toward the side away from the side opening 603. Specifically, the bottom surface of the engagement groove 602 has a stepped structure with a curvature, and a flat surface 6021 and two stoppers 6025 that protrude upward perpendicularly from both ends of the flat surface 6021 are formed in this order. The flat face 6021 is generally semi-circular in configuration and is disposed about the bottom opening 604. There is a level difference between the barrier portion 6025 and the flat face 6021, and the top face of the barrier portion 6025 is located above the flat face 6021. Therefore, when the mounting portion 81 of the connection head 80 is brought into contact with the flat surface 6021 when the connection head 80 is mounted in the engagement groove 602, and the mounting portion 81 of the connection head 80 is prevented from moving by the two stoppers 6025 when the mounting portion 81 of the connection head 80 moves toward the two stoppers 6025 due to the presence of the two stoppers 6025, the mounting portion 81 of the connection head 80 is prevented from coming out of the engagement groove 602, and the connection head 80 is prevented from coming out of the engagement groove 602 during the repair work. In addition, because the installation part 81 of the connector 80 is provided with the texture, friction force is increased between the installation part 81 of the connector 80 and the two blocking parts 6025, and the connector 80 is further effectively prevented from being separated from the clamping groove 602 during the repairing operation.

The connecting head 80 passes through the side opening 603 and then engages with the engaging groove 602 and the bottom opening 604, and the height of the bottom wall 622 is set to more reliably engage with one end of the connecting head 80 than if the bottom wall were completely flat, so that the connecting head 80 is not easily detached from the slider 60 during use.

It is understood that the step structures in the two embodiments described above can be machined by using a numerical control machine, but are not limited thereto, and can also be obtained by other machining methods.
