[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] The following is in conjunction with the appendix Figures 1-3 The hook assembly of this utility model embodiment will be described in detail.
[0030] The hook assembly of this utility model embodiment includes a base 1 and a locking member 2. The base 1 includes a seat body 11, a mounting part 12, and a hook part 13. The hook part 13 and the mounting part 12 are both disposed on the seat body 11, and the seat body 11, the mounting part 12, and the hook part 13 are integrally formed. The locking member 2 has a first end and a second end. The first end of the locking member 2 is pivotally connected to the mounting part 12, so that the second end of the locking member 2 can engage with and be disengaged from the end of the hook part 13 away from the seat body 11.
[0031] The hook assembly of this utility model is integrally formed with the hook part 13 and the base 11, which can prevent the hook part 13 from rotating relative to the base 11 while increasing the load-bearing capacity of the hook assembly. The locking member 2 is rotatable relative to the base 11, so that the locking member 2 can engage with the hook part 13 and move away, realizing the opening and closing of the hook part 13, preventing the object hung on the hook part 13 from falling off. Moreover, the structure is simple, not easy to be damaged, and has high reliability.
[0032] Specifically, such as Figures 1-3 As shown, the hook part 13 and the mounting part 12 are both located at the rear end of the base body 11. The first end of the locking member 2 is the front end of the locking member 2, and the second end of the locking member 2 is the rear end of the locking member 2. The front end of the locking member 2 is rotatably connected to the mounting part 12 so that the rear end of the locking member 2 can rotate relative to the base 1 in the up and down direction and can engage with and move away from the rear end of the hook part 13.
[0033] Compared to the existing technology that sets steel balls between the hook and the protrusion, this embodiment makes the base 11, the mounting part 12 and the hook part 13 integrally formed, which avoids the phenomenon that the object hung on the hook part 13 swings when the hook part 13 rotates. This simplifies the structure of the hook assembly, improves the structural strength of the hook assembly, and enhances the overall integrity and stability.
[0034] In some embodiments, the mounting portion 12 includes a first protrusion 121 and a second protrusion 122, the first protrusion 121 and the second protrusion 122 being spaced apart to form a mounting groove 123 between the first protrusion 121 and the second protrusion 122, and the first end of the locking member 2 engaging in the mounting groove 123 and pivotally connected to the first protrusion 121 and the second protrusion 122.
[0035] Specifically, such as Figures 1-3 As shown, the first protrusion 121 and the second protrusion 122 are arranged at intervals in the vertical direction. By fitting the first end of the locking member 2 into the mounting groove 123 and pivotally connecting it with the first protrusion 121 and the second protrusion 122, the connection stability between the locking member 2 and the base 1 is improved, while the structural compactness of the hook assembly is also improved.
[0036] In some embodiments, the locking member 2 contacts the side end face of the second protrusion 122 adjacent to the first protrusion 121 and is in clearance fit with the side end face of the first protrusion 121 adjacent to the second protrusion 122.
[0037] Specifically, such as Figures 1-3 As shown, the first protrusion 121 is located above the second protrusion 122. The upper end face of the second protrusion 122 contacts the locking member 2 to support the locking member 2. The lower end face of the first protrusion 121 is clearance-fitted with the locking member 2 to ensure that the locking member 2 rotates smoothly relative to the first protrusion 121 and the second protrusion 122.
[0038] In some embodiments, the end face of the first protrusion 121 away from the seat 11 is a first arcuate surface 1211, and the first end of the locking member 2 is provided with a recess 21. The first protrusion 121 fits into the recess 21. The wall surface of the recess 21 includes a bottom surface 211 and a side surface. The side surface of the recess 21 includes a second arcuate surface 212 opposite to the first arcuate surface 1211. The second arcuate surface 212 fits into the first arcuate surface 1211 so that the locking member 2 can rotate relative to the first protrusion 121.
[0039] Specifically, such as Figure 1 As shown, the rear end face of the first protrusion 121 is a first arc-shaped surface 1211. The upper front side of the locking member 2 is provided with a recess 21. The upper, left and right ends of the recess 21 are all open. The wall surface of the recess 21 includes a bottom surface 211 and a side surface. The bottom surface 211 of the recess 21 is in clearance fit with the lower end face of the first protrusion 121. The side surface of the recess 21 includes a second arc-shaped surface 212. Through the cooperation between the second arc-shaped surface 212 and the first arc-shaped surface 1211, the locking member 2 is ensured to rotate smoothly relative to the first protrusion 121, thereby realizing the opening and closing of the locking member 2.
[0040] In some embodiments, such as Figures 1-2 As shown, the hook assembly also includes a connector 3, which passes through the first protrusion 121, the locking member 2, and the second protrusion 122 and is connected to the second protrusion 122. The connector 3 enables the locking member 2 to be pivotally connected to the first protrusion 121 and the second protrusion 122.
[0041] In some embodiments, the connector 3 includes a first rod 31 and a second rod 32 connected together. The diameter of the first rod 31 is larger than the diameter of the second rod 32 to form a stepped surface 33 between the first rod 31 and the second rod 32. The second rod 32 is threadedly connected to the second protrusion 122, and the stepped surface 33 abuts against the second protrusion 122. By configuring the second rod 32 to be threadedly connected to the second protrusion 122 and the stepped surface 33 abutting against the second protrusion 122, the connector 3 is connected to the second protrusion 122 while ensuring that the connector 3 is properly connected to the second protrusion 122, thereby improving the reliability of the connection.
[0042] Specifically, such as Figures 1-2 As shown, the lower end of the first rod 31 is connected to the upper end of the second rod 32. The first rod 31 passes through the first protrusion 121 and the locking member 2. The second rod 32 passes through the second protrusion 122 and is threadedly connected to the second protrusion 122. The stepped surface 33 abuts against the upper end surface of the second protrusion 122.
[0043] In some embodiments, the connector 3 further includes a head 34, which is connected to the end of the first rod 31 away from the second rod 32. The first protrusion 121 has a groove 1212 on one side of its end face away from the second protrusion 122. At least a portion of the head 34 is located in the groove 1212 and is in clearance fit with the wall of the groove 1212.
[0044] Specifically, such as Figures 1-2 As shown, the head 34 is connected to the upper end of the first rod 31. The upper end face of the first protrusion 121 is provided with a groove 1212. By placing at least a part of the head 34 in the groove 1212, the exposed head 34 is reduced, and the overall coordination is improved. By gap fitting between the head 34 and the wall of the groove 1212, that is, there is a gap between the head 34 and the wall of the groove 1212, it is ensured that the locking member 2 rotates smoothly relative to the first protrusion 121.
[0045] In some embodiments, the hook assembly further includes a torsion spring 4, which is sleeved on the first rod 31. One end of the torsion spring 4 is connected to the locking member 2, and the other end of the torsion spring 4 is connected to the seat 11.
[0046] Specifically, such as Figures 1-2 As shown, the first rod 31 passes through the first protrusion 121 and the locking member 2. The torsion spring 4 is sleeved on the first rod 31 and located between the first protrusion 121 and the second protrusion 122. One end of the torsion spring 4 is connected to the locking member 2, and the other end of the torsion spring 4 is connected to the seat 11, thereby realizing the automatic closing of the locking member 2.
[0047] When the locking part 2 rotates to the right under the action of external force, the torsion spring 4 is compressed, and the rear end of the locking part 2 separates from the rear end of the hook, making it easier to hang objects on the hook part 13. After the external force disappears, the torsion spring 4 gradually extends and releases elastic potential energy to drive the rear end of the locking part 2 to rotate to the left, realizing the automatic closing of the locking part 2 and improving the convenience of the hook assembly.
[0048] In some embodiments, the locking member 2 has a first through hole 22, and the locking member 2 has a notch 23 on the side facing the seat 11 and the notch 23 communicates with the first through hole 22. The seat 11 has a second through hole 111, which is located between the first protrusion 121 and the second protrusion 122. The first rod 31 passes through the first through hole 22, and one end of the torsion spring 4 abuts against the inner wall surface of the first through hole 22. The other end of the torsion spring 4 passes through the notch 23 and abuts against the inner wall surface of the second through hole 111.
[0049] Specifically, such as Figures 1-2As shown, the locking member 2 has a first through hole 22 extending in the vertical direction, and the front side of the locking member 2 is provided with a notch 23 communicating with the first through hole 22. The seat body 11 is provided with a second through hole 111 extending in the front-back direction. One end of the torsion spring 4 abuts against the inner wall surface of the first through hole 22 to realize the connection between the torsion spring 4 and the locking member 2. The other end of the torsion spring 4 passes through the notch 23 and abuts against the inner wall surface of the second through hole 111 to realize the connection between the torsion spring 4 and the seat body 11.
[0050] In this embodiment, the notch 23 is provided to facilitate the contact between the other end of the torsion spring 4 and the inner wall of the second through hole 111, and to facilitate the installation of the torsion spring 4. In other words, when assembling the hook assembly, the torsion spring 4 is first installed in the first through hole 22 through the notch 23, and then the connector 3 is connected to the second protrusion 122 by passing through the first protrusion 121, the locking member 2, the torsion spring 4 in sequence.
[0051] In some embodiments, the hook portion 13 is provided with a first latching portion 131 at one end away from the seat 11, and the locking member 2 is provided with a second latching portion 24 at the second end. The second latching portion 24 can latch onto the first latching portion 131 and can be moved away from it.
[0052] Specifically, such as Figures 1-3 As shown, the rear end of the hook portion 13 is provided with a first engaging portion 131, and the rear end of the locking member 2 is provided with a second engaging portion 24. When the locking member 2 is open, the second engaging portion 24 moves away from the first engaging portion 131, making it easier to hang an object on the hook portion 13; when the locking member 2 is reset under the action of the torsion spring 4, that is, when the locking member 2 is closed, the second engaging portion 24 engages with the first engaging portion 131 to prevent the object from falling off the hook portion 13, and the first engaging portion 131 can also limit the movement of the second engaging portion 24 to prevent the locking member 2 from over-resetting.
[0053] In some embodiments, the base 11 is provided with a blind hole 112, and a boss 113 opposite to the blind hole 112 is provided on the side of the base 11 away from the hook portion 13. The boss 113 is provided with a positioning hole communicating with the blind hole 112. The blind hole 112 and the positioning hole facilitate the installation of the hook assembly on the mobility scooter.
[0054] like Figures 1-3 As shown, the boss 113 is located at the rear end of the seat 11. The boss 113 reduces the opening size of the mobility scooter, making it easier to connect the boss 113 to the internal structure of the mobility scooter and improving the connection stability between the hook assembly and the mobility scooter.
