Description

Technical Field

[0001] The utility model relates to the technical field of hooks, and more specifically to a hook structure and a bracket with the hook structure. Background Art

[0002] The existing hook structure of the car seat backrest is relatively simple, and the hook is usually set as a fixed and non-adjustable structure, which is inconvenient to use. And because the hook structure cannot be adjusted, when the hook is facing the passenger, the more protruding part of the hook is not conducive to the anti-collision protection of the passenger during the car driving. In addition, the existing car seat backrest hook structure has a relatively simple function, for example, it only has the function of hooking. With the popularization of automobile applications and the improvement of passengers' requirements for riding convenience, for example, they want to support and fix electronic devices such as mobile phones for watching audio and video or navigation. If a hook that is only used to hook items is installed in the car, and a bracket that is only used to support and fix electronic devices such as mobile phones is installed, it is not only very inconvenient to use, but also makes the car look too messy, affecting the riding experience of passengers.

[0075] The hook assembly 2 is installed on the first bottom shell 102. When installing, the two hooks 20 need to be placed in the two receiving grooves 1026 in a state where the concave surfaces face each other, so that the eighth through hole 2020 on the hook 20 is aligned with the first through hole 10201, the ninth through hole 2021 is aligned with the second through hole 10202, and the three fourth protrusions 201 in the shape of gears on the two hooks 20 are meshed with each other. Then the first cover shell 101 needs to be covered on the first receiving cavity 1020 of the first bottom shell 102, and the second receiving cavity 1010 is opposite to the first receiving cavity 1020. When the cover is closed, the first limiting column 1013 is inserted into the first through hole 10201 and the eighth through hole 2020, and the second limiting column 1014 is inserted into the second through hole 10202 and the ninth through hole 2021; and the first convex column 1012 corresponds to the first connecting column 1024 one by one, so that the fourth through hole 10120 in the first convex column 1012 will be aligned with the internal thread hole in the first connecting column 1024, and then screws (not shown in the drawings) are used for fastening, so that the first cover shell 101 can be fixedly installed on the first bottom shell 102. When the first shell 10 is installed, the linkage connection of the two hooks 20 is realized. The two hooks 20 can be relatively opened or stored in the corresponding receiving grooves 1026.

[0076] The turntable 11 is rotatably connected to the first cover shell 101. During installation, the second convex column 1016 is passed through the fifth through hole 1110, and the second protrusion 110 is received in the second recess 1015. Then, a screw (not shown in the drawings) is connected to the third through hole 10160 with internal threads, and one end of the second convex column 1016 passing through the fifth through hole 1110 is limitedly connected to the fourth recess 111 by means of a screw (not shown in the drawings). The ball 115 partially protrudes from the sixth through hole 1140 and is placed in one of the third recesses 1017. After the turntable 11 and the first cover shell 101 are installed in place, the ball 115 and the plurality of third recesses 1017 realize mutual rotational positioning cooperation.

[0077] The clamping assembly 3 is installed on the second shell body 12. During installation, the two sets of connecting rods 30 provided with springs 31 together with parts of the springs 31 are placed correspondingly in the two fourth grooves 1251, and the ends of the two connecting rods 30 provided with external threads (i.e., the ends away from the fifth protrusion 301) are correspondingly extended through the two third openings 1210 to the outside of the second shell body 12, and then threadedly connected with the clamping seat 32 through the external threads.

[0078] The second shell 12 is fixedly connected to the turntable 11. During installation, the third accommodating cavity 125 on the second shell 12 is surrounded by the outer periphery of the turntable 11. The fourth protrusion 1250 in the third accommodating cavity 125 can be placed between the two first protrusions 112 on the turntable 11, and the two first protrusions 112 will correspondingly abut and cover the notches of the two fourth grooves 1251 and form an accommodating cavity between the fourth groove 1251, so that the connecting rod 30 and the spring 31 in the fourth groove 1251 can be stably limited therein, and the two second protrusions 1121 and the two third protrusions 1122 on the two first protrusions 112 can be correspondingly accommodated in the two third openings 1210, so as to limit the end of the spring 31 away from the fifth protrusion 301, so that the two ends of the spring 31 are stably limited in the fourth groove 1251, realizing the effect of elastic clamping. At the same time, the third bosses 1252 correspond one by one with the third connecting columns 113, and the seventh through holes 12520 in the third bosses 1252 are aligned with the internal threaded holes in the third connecting columns 113, and then screws (not shown in the drawings) are used to tighten them, so that the second shell 12 can be fixedly installed on the turntable 11.

[0079] The magnetic element 4 is a magnet. The magnetic element 4 is installed in the third groove 124 (i.e., the magnetic element receiving area). When installing, the magnetic elements 4 are placed one by one in the third groove 124 (i.e., the magnetic element receiving area), and then the cover plate 1240 is used to cover the third groove 124 (i.e., the magnetic element receiving area).

[0080] It should be noted that in other embodiments, the magnetic suction component receiving area can also be circular or annular, and correspondingly, the shape of the magnetic suction component 4 should also be circular or annular. The figure shown in the present embodiment is only one of the implementation methods. In actual application, it can be designed and selected according to actual use requirements.

The mounting through hole 3001 at one end of the connector 300 is used to pass through the first opening 10200 and connect to the second connecting column 1025 by screws (not shown in the figure). Fig.13 As shown in FIG. 1 , the mounting through hole 3001 at the other end of the connecting member 300 is used to connect with the mounting fixing portion 200. The connecting member 300 is a flexible metal member.

[0084] like Fig.11 , 13 and Fig.14 As shown in the figure, the installation fixing part 200 includes a first half locking part 2001 and a second half locking part 2002 rotatably connected to the first half locking part 2001. The first half locking part 2001 and the second half locking part 2002 are engaged with each other and can be fixedly mounted on the seat headrest rod.

[0085] like Fig.14 As shown in the figure, the bottom wall of the second half locking portion 2002 is provided with a socket 20021 for inserting the other side of the connecting piece 300, and a stud 20022 is also provided in the second half locking portion 2002 at the position of the socket 20021, so that the other side of the connecting piece 300 can be connected to the second half locking portion 2002 by screw connection (not shown in the figure).

[0086] In other embodiments, the bottom wall of the second half locking portion 2002 and the other side of the connecting member 300 may also be designed as an integrally formed connecting structure.

[0087] It should be understood that ordinary technical workers in the field can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
