[0012] (III) Beneficial Effects This invention provides an ISOFIX cover that is easy to install. It has the following advantages: 1. Through the action of the external support mechanism, the cover plate can be installed on the housing without the aid of external tools. Pushing the two top pins towards the center of the auxiliary strip compresses the corresponding springs, causing them to deform and align the outer ends of the two top pins with the corresponding sides of the auxiliary strip. Moving the cover plate perpendicular to the groove pushes the two top pins into the groove. Under the action of the two springs, the corresponding top pins are pushed outward, causing them to insert into the corresponding slots in the housing. This allows for quick installation of the cover plate without the need for external tools.

[0013] 2. The locking mechanism can fix the cover plate in a state perpendicular to the bottom of the inner surface of the housing, sealing the opening of the housing and preventing children's fingers from getting stuck in the housing. The locking plate is adjusted to a horizontal state by the locking shaft. After the cover plate is flipped to a state perpendicular to the bottom of the inner surface of the housing, the torque applied to the locking shaft is released. Under the action of the torsion spring, the locking shaft is flipped and twisted, causing the locking plate to lock into the arc-shaped locking groove in the housing, restricting the flipping of the cover plate. This has the function of fixing the cover plate and preventing it from flipping over and causing injury to children's fingers. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides an easy-to-install ISOFIX cover, comprising: Casing 1; The external support mechanism 2 is located inside the housing 1. The external support mechanism 2 includes a cover plate 201 located on one side of the inner cavity of the housing 1. An auxiliary strip 202 is installed on one side of the cover plate 201. Top pins 204 adapted to the housing 1 are symmetrically arranged inside the auxiliary strip 202.

[0023] like Figure 2 As shown, in this embodiment, a groove 205 adapted to the cover plate 201 is provided on one side of the housing 1. The cover plate 201 and the auxiliary strip 202 are rotatably connected inside the groove 205. Under the action of the groove 205, when the cover plate 201 is flipped upward around the top pin 204, a certain space is provided, so that the cover plate 201 can be flipped at an angle of more than ninety degrees, which facilitates the installation of the child seat.

[0024] like Figure 3 As shown, in this embodiment, a spring 203 is provided on one side of the top pin 204, and circular grooves 206 adapted to the top pin 204 are symmetrically opened on both sides of the auxiliary strip 202. A retaining groove adapted to the top pin 204 is symmetrically opened on the inner surface of the housing 1. After the top pin 204 is pushed into the circular groove 206, the cover plate 201 is vertically pushed into the inner cavity of the housing 1. The spring 203 pushes the top pin 204 into the corresponding retaining groove of the housing 1, allowing the cover plate 201 to be installed on the housing 1 without the aid of external tools.

[0025] like Figure 3 As shown, in this embodiment, the top pin 204 is slidably connected inside the circular groove 206, the spring 203 is located inside the circular groove 206, and one end of the top pin 204 is movably inserted into the slot. Under the action of the spring 203, the top pin 204 is pushed into the slot in the direction corresponding to the slot. When the cover plate 201 is flipped, it is flipped by using the top pin 204 as a pivot.

[0026] Next, place the cover plate 201 parallel to the housing 1, and manually push both top pins 204 toward the center of the auxiliary strip 202 until the outer ends of the two top pins 204 are pushed to coincide with the corresponding sides of the auxiliary strip 202. The top pins 204 will compress the corresponding springs 203, causing them to deform and bringing the vertical cover plate 201 closer to the inner cavity of the housing 1 until both sides of the auxiliary strip 202 are attached to the inner surface of the housing 1. Push the cover plate 201 again. At this time, under the action of the springs 203, an outward pushing force is applied to the top pins 204 until the top pins 204 hit the housing 1 with a snapping sound. Once both top pins 204 are snapped into the corresponding slots of the housing 1, the installation of the cover plate 201 is completed.

[0027] Example 2 Reference Figure 4 and Figure 5This is the second embodiment of the present invention, which is based on the previous embodiment. The locking mechanism 3 is located inside the cover plate 201. The locking mechanism 3 includes an inner groove post 301 installed inside the cover plate 201. A locking shaft 303 is movably installed inside the inner groove post 301. A limit ring 305 is provided on the outer surface of the locking shaft 303. A torsion spring 304 is provided on one side of the limit ring 305. An installation post 306 is installed on one side of the locking shaft 303. A locking plate 307 adapted to the housing 1 is provided on the outer surface of the installation post 306.

[0028] like Figure 4 As shown, in this embodiment, a mounting hole adapted to the inner groove post 301 is provided on one side of the cover plate 201. The inner groove post 301 is fixed inside the mounting hole. An arc-shaped locking groove adapted to the locking plate 307 is provided on the top of the inner surface of the housing 1. The locking plate 307 is movably engaged inside the arc-shaped locking groove. When the locking shaft 303 is twisted, it drives the mounting post 306 to rotate, causing the locking plate 307 to engage in the arc-shaped locking groove. Under the action of the torsion spring 304, the reverse rotation of the locking plate 307 is restricted, thus fixing the cover plate 201 in the housing 1.

[0029] like Figure 5 As shown, in this embodiment, an outer ring 302 is installed on one side of the inner groove post 301, and the other end of the torsion spring 304 is connected to the outer ring 302. One side of the outer ring 302 is flush with the outer surface of the cover plate 201, and the torsion spring 304 is located outside the locking shaft 303. Under the action of the torsion spring 304, and with the assistance of the limiting ring 305, a torque is applied to the locking shaft 303 to ensure that the locking shaft 303 will not rotate when no external force is applied.

[0030] Furthermore, a flat strip is inserted into the locking shaft 303, and a clockwise torque is applied to the locking shaft 303. The locking shaft 303 drives the limiting ring 305 and the mounting post 306 to rotate. With the cooperation of the outer ring 302, the limiting ring 305 twists the torsion spring 304. The mounting post 306 drives the locking plate 307 to rotate. After the locking plate 307 is rotated to a horizontal state, the cover plate 201 is flipped downward around the top pin 204 until it is perpendicular to the bottom of the inner surface of the housing 1. At this time, the torque applied to the locking shaft 303 is removed. Under the action of the torsion spring 304, the limiting ring 305 is twisted in the opposite direction, causing the locking shaft 303 to flip and twist. The locking shaft 303 drives the mounting post 306 to twist in the opposite direction, and the mounting post 306 drives the locking plate 307 to twist in the opposite direction. The locking plate 307 is twisted and rotated and locked into the arc-shaped locking groove of the housing 1, thus completing the fixation of the cover plate 201.

[0031] Working principle: Place the cover plate 201 parallel to the housing 1. Manually push both top pins 204 towards the center of the auxiliary strip 202 until the outer ends of the two top pins 204 are aligned with the corresponding auxiliary strip 202. The top pins 204 compress the corresponding springs 203, causing them to deform and bringing the vertical cover plate 201 closer to the inner cavity of the housing 1 until both sides of the auxiliary strip 202 are against the inner surface of the housing 1. Push the cover plate 201 again. At this time, under the action of the springs 203, an outward pushing force is applied to the top pins 204 until a sound is heard as the top pins 204 strike the housing 1 and lock. Once both top pins 204 are engaged in the corresponding slots in the housing 1, the installation of the cover plate 201 is completed. Then, insert a flat strip into the locking shaft 303 and press the locking shaft 303 into place. 03. Apply clockwise torque, and the locking shaft 303 drives the limiting ring 305 and the mounting post 306 to rotate. With the cooperation of the outer ring 302, the limiting ring 305 twists the torsion spring 304. The mounting post 306 drives the locking plate 307 to rotate. After the locking plate 307 is rotated to a horizontal state, the cover plate 201 is flipped downward around the top pin 204 until it is perpendicular to the bottom of the inner surface of the housing 1. At this time, the torque applied to the locking shaft 303 is removed. Under the action of the torsion spring 304, the limiting ring 305 is twisted in the opposite direction, causing the locking shaft 303 to flip and twist. The locking shaft 303 drives the mounting post 306 to twist in the opposite direction. The mounting post 306 drives the locking plate 307 to twist in the opposite direction, twisting and rotating the locking plate 307 into the arc-shaped locking groove of the housing 1, thus completing the fixation of the cover plate 201.
