Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 7 As shown, a car carpet fixing device includes a fixing mechanism 200, which is installed in a car base 100 via an installation mechanism 300. The fixing mechanism 200 includes a steel pin 201 fixedly installed on the car carpet 101 and a snap-fit ​​seat 203 detachably mounted on the car base 100 via the installation mechanism 300. The snap-fit ​​seat 203 is provided with an installation component that cooperates with the steel pin 201 to fix the steel pin 201.

[0024] In this embodiment, the mounting component includes a snap-fit ​​groove 204 formed within the snap-fit ​​base 203. A fixing cover 205 coaxially disposed within the snap-fit ​​groove 204 is fixedly arranged therewith. The fixing cover 205 tapers inward near its top to form an inclined surface 212. A metal cup 206 of the same shape as the fixing cover 205 is slidably fitted within the fixing cover 205. A locking member for locking the steel needle 201 is provided within the metal cup 206. The locking member includes a fixing plate 207 fixedly disposed within the metal cup 206 and coaxially disposed therewith. The snap-fit ​​groove 204... A spring 208 is fixedly installed on the bottom wall. The top end of the spring 208 abuts against the fixing plate 207. Multiple sets of steel balls 209 are slidably arranged in the cavity of the metal cup 206 above the fixing plate 207. The inner side wall of the metal cup 206 has a relief groove 211 that is the same number as the steel balls 209 and corresponds to them one by one. The snap-fit ​​seat 203, the fixing cover 205 and the metal cup 206 all have through holes in the middle. The size of the through holes is adapted to the diameter of the steel needle 201. The circumferential surface of the steel needle 201 has a limiting groove 202 that is used to cooperate with the multiple sets of steel balls 209.

[0025] When the steel needle 201 is inserted into the through hole of the locking seat 203, it first contacts the opening of the metal cup 206. As the steel needle 201 continues to be inserted, the metal cup 206 slides downward inside the fixing cover 205, compressing the spring 208. During the downward movement of the metal cup 206, the steel ball 209 moves towards the center along the inclined surface 212 of the fixing cover 205, preparing to lock the steel needle 201. When the steel needle 201 is fully inserted, the steel ball 209 falls into the limiting groove 202 of the steel needle 201, achieving locking. To pull out the steel needle 201, pull the steel needle 201 outward. At this time, the steel needle 201 drives the steel ball 209 to move upward. The steel ball 209 is subjected to an inward force from the inclined surface 212. The higher the steel ball 209 moves, the smaller the gap in the middle, and the tighter the steel needle 201 will be clamped, achieving locking. The steel ball 209 is guided to move by the inclined surface 212 of the fixed cover 205 to achieve gradual locking and avoid damage to components caused by instantaneous forceful locking.

[0026] In this embodiment, the fixing cover 205 is made of high-strength plastic, and the top of the metal cup 206 is fixed with a first magnetic block 210 facing upwards.

[0027] When the steel needle 201 is inserted, the metal cup 206 is squeezed and slides down, the spring 208 is compressed, and the steel ball 209 locks the steel needle 201 under the action of the inclined surface 212; after the insertion is completed, the first magnetic block 210 is in a ready-to-fit state.

[0028] In this embodiment, the mounting mechanism 300 includes a mounting groove 301 formed in the car base 100 and adapted to the shape of the card holder 203. A second magnet 302 is fixedly provided on the inner side wall of the mounting groove 301, and a magnet 303 that cooperates with the second magnet 302 is fixedly provided on the outer side wall of the card holder 203.

[0029] Align the snap-fit ​​base 203 with the magnet 303 with the mounting groove 301. When they are close together, the magnet 303 and the second magnetic block 302 attract each other due to their magnetism, which helps the snap-fit ​​base 203 to quickly and accurately embed into the mounting groove 301. After installation, the magnetic attraction makes the snap-fit ​​base 203 firmly fixed in the mounting groove 301. When disassembling, the snap-fit ​​base 203 can be removed from the mounting groove 301 by overcoming the magnetic attraction.

[0030] In this embodiment, the positive pole of the second magnetic block 302 faces upward and can be used in conjunction with the first magnetic block 210.

[0031] When the car carpet 101 needs to be removed, the snap-fit ​​seat 203 is taken out of the mounting slot 301, so that the side of the needle cap of the steel needle 201 faces the second magnetic block 302. The second magnetic block 302 and the first magnetic block 210 repel each other because they are the same pole, so that the metal cup 206 drives the steel ball 209 to move downward. The steel ball 209 slides out of the limiting slot 202, and the unlocking is completed.

[0032] Working process and principle: When using this device, lift the car carpet 101, align the steel needle 201 at the bottom of the carpet with the opening of the locking seat 203, and press down or push the car carpet 101. When the steel needle 201 is inserted into the through hole of the locking seat 203, it first contacts the opening of the metal cup 206. As the steel needle 201 continues to be inserted, the metal cup 206 slides downward within the fixing cover 205, compressing the spring 208. During the downward movement of the metal cup 206, the steel ball 209 moves towards the center along the inclined surface 212 of the fixing cover 205, preparing to lock the steel needle 201. When the steel needle 201 is fully inserted, the steel ball 209 falls precisely into the limiting groove 202 of the steel needle 201, achieving locking. To remove the steel needle 201, pull the steel needle 201 outward. At this time, the steel needle 201 drives the steel ball 209 to move upward. The steel ball 209 is subjected to the inward force of the inclined surface 212, and the steel ball... As 209 moves upward, the gap in the middle becomes smaller, and the steel needle 201 is clamped tighter to achieve locking. During installation, the snap-fit ​​base 203 with magnet 303 is aligned with the mounting groove 301. When they are close together, magnet 303 and the second magnetic block 302 attract each other due to magnetism, which helps snap-fit ​​base 203 to quickly and accurately embed into the mounting groove 301. After installation, the magnetic attraction makes snap-fit ​​base 203 firmly fixed in the mounting groove 301. During disassembly, the snap-fit ​​base 203 can be removed from the mounting groove 301 by overcoming the magnetic attraction. When it is necessary to remove the car carpet 101, snap-fit ​​base 203 is removed from the mounting groove 301, so that the side of the needle cap of steel needle 201 faces the second magnetic block 302. The second magnetic block 302 and the first magnetic block 210 repel each other because they are the same pole, which causes the metal cup 206 to move the steel ball 209 downward. The steel ball 209 slides out of the limiting groove 202, completing the unlocking.

[0033] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
