Detailed Implementation Methods

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 This is a structural diagram of the lifting device 100 provided by this utility model. The lifting device 100 provided by this utility model has a simple connection structure between the spring, handle, and mounting base, which is easy to process, has strong connection stability, and can extend its service life.

[0026] Please see Figure 2 and Figure 3 The lifting device 100 includes a handle 10, a mounting base 20, and a spring 30.

[0027] Please see Figures 4 to 6 The handle 10 has a mounting post 11 on one side, and the mounting surface 201 of the mounting base 20 has a mounting groove 202, in which the mounting post 11 is received. The spring 30 includes a coil 31 and a power arm 32 and an assist arm 33 extending from both ends of the coil 31. The coil 31 is mounted on the mounting post 11, and the power arm 32 is engaged with the mounting post 11, while the assist arm 33 is engaged with the mounting groove 202. The handle 10 and the mounting base 20 are movably connected by the spring 30.

[0028] Specifically, the spring 30 includes a coil 31 and a power arm 32 and an assist arm 33 extending from both ends of the coil 31. The power arm 32 is engaged with the mounting post 11, and the assist arm 33 is engaged with the mounting groove 202. This realizes the movable connection between the handle 10 and the mounting base 20 through the spring 30. That is, the coil 31 is installed on the mounting post 11 of the handle 10, and the power arm 32 and the assist arm 33 are respectively connected to the mounting post 11 of the handle 10 and the mounting groove 202 of the mounting base 20. Furthermore, the mounting post 11 is received within the mounting groove 202. This design enables the connection between the handle 10 and the mounting base 20 via the power arm 32 and the auxiliary arm 33 of the spring 30. During use, the handle 10 rotates relative to the mounting base 20, and the power arm 32 and the auxiliary arm 33 are subjected to force, compressing the coil 31. When the handle 10 rotates to be perpendicular to the plane where the mounting base 20 is located, it can achieve the lifting function for use. After use, the coil 31 is released, and the power arm 32 and the auxiliary arm 33 can push the handle 10 and the mounting base 20 to reset. After reset, the handle 10 and the mounting base 20 are in the same plane and do not occupy space.

[0029] Therefore, the lifting device 100 provided by this utility model has a mounting post 11 on one side of the handle 10, and a mounting groove 202 is opened on the mounting surface 201 of the mounting base 20. The mounting post 11 is housed in the mounting groove 202. The spring 30 includes a coil 31 and a power arm 32 and an assist arm 33 extending from both ends of the coil 31. The coil 31 is mounted on the mounting post 11, and the power arm 32 is held on the mounting post 11. The assist arm 33 is held in the mounting groove 202. The handle 10 and the mounting base 20 are movably connected through the spring 30, realizing the connection between the handle 10 and the mounting base 20 through the power arm 32 and the assist arm 33 of the spring 30. The connection structure between the spring 30 and the handle 10 and the mounting base 20 is simple, easy to process, has strong connection stability, and can extend the service life.

[0030] The handle 10 is roughly triangular in shape. The handle 10 includes a grip post 12 and two connecting posts 13 formed by bending and extending inward from both ends of the grip post 12 (i.e., in the direction of mutual approach). The ends of the two connecting posts 13 form an opening at the apex of the triangle. The two connecting posts 13 are symmetrically arranged. One end of each of the two connecting posts 13 extends away from the grip post 12 to form two mounting blocks 14. There are two mounting posts 11. The two mounting posts 11 are respectively set on the two mounting blocks 14. Both mounting posts 11 are parallel to the grip post 12.

[0031] Specifically, the mounting posts 11 are all arranged parallel to the grip posts 12, which facilitates lifting and pulling. The connection between the connecting post 13 and the grip post 12 is arc-shaped. The grip post 12 has an annular recess 121. A handle 122 is fitted on the grip post 12. The handle 122 is located in the recess 121. The handle 122 is fitted on the grip post 12, which can increase the grip friction and facilitate lifting and pulling.

[0032] In some embodiments, one end of the mounting post 11 extends outward in its axial direction to form a snap-fit ​​portion 111. The snap-fit ​​portion 111 has a snap-fit ​​groove 112 that penetrates the outer peripheral surface of the snap-fit ​​portion. Specifically, the snap-fit ​​portion 11 is used to sleeve the coil 31, and the snap-fit ​​groove 112 is used to hold the power arm 32. The connection method is simple and the connection stability is strong.

[0033] The mounting post 11 is cylindrical, and the snap-fit ​​part 111 is also cylindrical. The diameter of the snap-fit ​​part 111 is smaller than the diameter of the mounting post 12. With this design, when the coil 31 is sleeved on the snap-fit ​​part 111, one end of the coil 31 can abut against the end face of the mounting post 11, which plays a limiting role and prevents the spring 30 from shifting position.

[0034] The mounting base 20 is generally rectangular and includes an outer surface 203 opposite to the mounting surface 201. The mounting surface 201 is the surface that contacts and is fixed to the lifting member. The mounting base 20 has a through hole 204 penetrating the outer surface 203 and the mounting surface 201. The through hole 204 is used to insert a fastener to fix it to the lifting member. The fastener can be a bolt. The bolt passing through the through hole 204 can fix the mounting base 20 to the outer wall of the lifting member. The mounting surface 201 also has a positioning groove 205 located between two adjacent through holes 204. The positioning groove 205 is used to engage with a protrusion on the outer wall of the lifting member for positioning, preventing the mounting base 20 from shifting position when fixed to the lifting member.

[0035] In this embodiment, there are five through holes 204 and two positioning slots 205. Four through holes are respectively located at the four top corners of the rectangular mounting base, one through hole is located in the middle of the long side of the rectangular mounting base, and two positioning slots 205 are respectively located on both sides of the through hole. That is, the positioning slots, through holes, and positioning slots are arranged along the long side of the rectangle. The two positioning slots and the through hole are located on the side of the mounting base away from the handle, which facilitates installation and positioning.

[0036] There are two mounting slots 202, and their structures roughly correspond to those of the mounting post 11. Both mounting slots 202 are arranged along the long side of the rectangular mounting base. Further, one end of the mounting slot 202 near the edge of the mounting base 20 extends downward to form a connecting slot 206. The connecting slot 206 is located on one side of the mounting slot 205, specifically on the side of the mounting slot 202 away from the handle 10. The connecting slot 206 connects to the mounting slot 202 and is used to accommodate and hold the assist arm 33. The two connecting slots 206 are respectively located near the two short sides of the rectangular mounting base. The connecting slots 206 and the mounting slots 202 hold the assist arm 33. The connection between the spring 30 and the mounting base 20 is simple and provides strong connection stability.

[0037] Furthermore, the mounting base 20 has two symmetrical notches 207 on the side near the handle 10, and a protrusion 21 is formed between the two notches 207. Specifically, the two notches 207 are opposite to and connected to the two mounting grooves 202. The two mounting posts 11 are respectively housed in the two mounting grooves 202, and the two mounting blocks 14 of the handle 10 are respectively housed in the two notches 207. The protrusion 21 is located between the two mounting blocks 14, that is, the opening at the top corner of the handle 10 can form a support engagement with the protrusion 21 of the mounting base 20, so that the handle 10 is supported after rotating at a certain angle, providing greater support force so that it can have the function of lifting objects such as the engine compartment.

[0038] Furthermore, the two ends of the mounting base 20 extend towards the handle 10 to form two inclined surfaces 22. The two inclined surfaces 22 are located on the side of the two mounting grooves 202 near the handle 10, and the slope of the inclined surface 22 is consistent with the slope of the connecting post 13 of the handle 10, which can avoid structural interference when the handle rotates.

[0039] In this embodiment, the mounting groove 202 and the positioning groove 205 are both provided on the mounting surface 201 of the mounting base 20, which can ensure the surface flatness of the outer surface 203 of the mounting base 20. The connection structure is provided on the inner mounting surface 201, which can prevent the connection structure from being damaged by the outside world and further improve its service life.

[0040] There are two springs 30, each mounted on a separate mounting post 11. The coil 31 is circular with multiple turns. The power arm 32 is arranged radially along the coil 31, extending beyond the circular edge of the coil 31; that is, the projection of the power arm 32 falls inside the coil 31. The straight line of the power arm 32 is parallel to the circular plane of the coil 31, and the length of the power arm 32 is less than the diameter of the coil 31. The coil 31 is fitted onto the snap-fit ​​part 111, and the power arm 32 is engaged within the snap-fit ​​groove 112. Specifically, when the coil 31 is fitted onto the snap-fit ​​part 111, the power arm 32 can extend into the snap-fit ​​groove 112, thereby limiting the position of the power arm 32 and connecting the spring 30 to the handle 10.

[0041] The length of the assist arm 33 is greater than the diameter of the coil 31. The assist arm 33 is arranged along the tangent direction of the coil 31. One end of the assist arm 33 abuts against the inner wall of the connecting groove 206 and does not extend beyond the mounting surface 201. Specifically, it can be flush with the mounting surface 201 to ensure the flatness of the mounting surface 201 and facilitate installation. The assist arm 33 is held in the mounting groove 202 and the connecting groove 206, which can limit the position of the assist arm 33 and realize the connection between the spring 30 and the mounting base 20.

[0042] The spring 30 in this application is a circular coil 31 with a power arm 32 and an auxiliary arm 33. The shorter power arm 31 is locked onto two mounting posts 11 on one side of the handle 10, specifically inside a cylindrical mounting post 111 with a locking groove 112. The longer auxiliary arm 33 is placed in the mounting groove 202 and connecting groove 206 of the mounting base 20, realizing the movable connection between the handle 10 and the mounting base 20 through the spring 30. The connection structure between the spring 30 and the handle 10 and the mounting base 20 is simple, easy to process, has strong connection stability, is not easily damaged, and can extend the service life.

[0043] In summary, the lifting device 100 provided by this utility model has a mounting post 11 on one side of the handle 10, and a mounting groove 202 is opened on the mounting surface 201 of the mounting base 20. The mounting post 11 is housed in the mounting groove 202. The spring 30 includes a coil 31 and a power arm 32 and an assist arm 33 extending from both ends of the coil 31. The coil 31 is mounted on the mounting post 11, and the power arm 32 is held on the mounting post 11. The assist arm 33 is held in the mounting groove 202. The handle 10 and the mounting base 20 are movably connected through the spring 30, realizing the connection between the handle 10 and the mounting base 20 through the power arm 32 and the assist arm 33 of the spring 30. The connection structure between the spring 30 and the handle 10 and the mounting base 20 is simple, easy to process, has strong connection stability, and can extend the service life.
