DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides a chassis, such as Figures 1 to 7 As shown, it includes a chassis shell 1, two connection ports 2 are arranged on the top of one side of the chassis shell 1, two headphone holes 3 are arranged on one side of the connection ports 2, and adjustment structures are arranged on the outer sides of the two connection ports 2 and the headphone holes 3; The adjustment structure includes a mounting seat 4, a first electric push rod 5, a protective block 6, a limiting structure, an electric telescopic plate 7 and a telescopic block 8. The first electric push rod 5 is fixedly installed on one side of the top of the mounting seat 4. Two protective blocks 6 are fixedly installed on the top of the first electric push rod 5. The two protective blocks 6 are respectively located on the top of the two connecting ports 2. One end of the mounting seat 4 is located outside the two connecting ports 2, and the other end is located outside the headphone jack 3. The limiting structure is arranged inside the two protective blocks 6. The electric telescopic plate 7 is arranged inside the side of the mounting seat 4 away from the protective block 6. The telescopic block 8 is slidably connected to the top of the electric telescopic plate 7.

[0019] By starting the first electric push rod 5, the protective block 6 is moved to the top of the chassis shell 1, and then the mobile phone data cable is inserted into the inside of the protective block 6, so that its bottom end corresponds to the connecting port 2, and the two sides of the data cable are limited by the limiting structure so that it is limited inside the protective block 6, and then the first electric push rod 5 drives the protective block 6 to move downward into the groove, and at the same time, the bottom end of the mobile phone data cable is plugged into the connecting port 2, so as to facilitate quick plugging, and the connecting end can also be protected to prevent long-term plugging and unplugging from damaging the data cable plug-in end, and prevent loosening and poor contact caused by collision, which affects use. When it is necessary to connect the earphone, the earphone cable is inserted into the earphone jack 3, and the electric telescopic plate 7 drives the telescopic block 8 to extend, so that one end of the electric telescopic plate 7 and the telescopic block 8 are moved to the top of the chassis shell 1, and the outside of the earphone cable connection end is protected. In addition, the data cables and the data cables and the earphone cables are separated by the protective block 6 and the electric telescopic plate 7 to prevent the mobile phone data cable and the bottom end of the earphone cable from being entangled, thereby improving the use effect.

[0020] like Figures 2 to 4 As shown, a groove is provided at the top of the chassis shell 1 and located outside the two connection ports 2 and the two headphone jacks 3, a power button is provided on one side of the groove and located at the top of the chassis shell 1, a control button is provided on one side of the power button, a first baffle 9 is provided on one side of the protective block 6 and located on the top of the mounting seat 4, the mounting seat 4 is fixedly installed on the inner wall of the bottom of the groove, both sides of the two protective blocks 6 are slidably connected to the inner wall of the groove, both ends of the two protective blocks 6 are provided with mounting grooves, the limiting structure is located inside the mounting groove, and it is symmetrically arranged with the center of the protective block 6.

[0021] The groove is convenient for installing the mounting seat 4 and the protective block 6. The chassis is started and used by controlling the power button. The first electric push rod 5 and the electric telescopic plate 7 are controlled to move by the control button, which is convenient for protecting the outer side of the connection end of the data cable and the headphone cable. When the data cable needs to be unplugged, the first electric push rod 5 is started to drive the protective block 6 to move upward, so that the protective block 6 drives the data cable to move upward to the top of the groove, so that the data cable connection end is separated from the connection port 2, thereby facilitating the plugging and unplugging of the data cable and preventing the connection end from being damaged and affecting the use due to the plugging and unplugging of the mobile phone data cable. The first baffle 9 can be used to block the top of the headphone jack 3 when the headphone jack 3 is not in use to prevent dust from entering the headphone jack 3 and affecting the use. The limiting structure is installed through two mounting grooves. When the data cable is placed in the protective block 6, the symmetrically arranged limiting structure improves the stability of the limitation on both sides of the data cable, thereby facilitating the protective block 6 to drive the data cable to move to the inside of the groove and plug it into the connection port 2, thereby improving the use effect.

[0022] like Figures 5 to 7 As shown, a ring groove is provided on the side of the mounting seat 4 away from the protective block 6, the electric telescopic plate 7 is fixedly installed with the ring groove, there are two telescopic blocks 8, and one side of the telescopic ends thereof is connected, and the two headphone jacks 3 are located in the middle of the electric telescopic plate 7 and the telescopic block 8.

[0023] The annular groove facilitates the installation of the electric telescopic plate 7. When two earphone wires are inserted into the earphone jack 3, the control button is pressed to drive the electric telescopic plate 7 to drive the telescopic block 8 to move upward, so that the electric telescopic plate 7 and the telescopic block 8 move to the top of the chassis shell 1, shielding and protecting the outer side of the earphone wire, separating the earphone wire from the mobile phone data cable without entanglement. When only one earphone wire is plugged in, the telescopic block 8 on one side is moved so that the telescopic block 8 pushes the telescopic block 8 on the other side to retract, and the two telescopic blocks 8 are moved to the side where the earphone wire is plugged in. The earphone wire is protected by the retracted two telescopic blocks 8, thereby improving the applicability of use and facilitating use.

[0024] like Figure 3 to Figure 4As shown, the limiting structure includes a limiting plate 10, a first rack 11, a gear 12, a rotating rod 13, a second rack 14, a connecting spring and a clamping plate 15.

[0025] When the data cable is inserted into the protective block 6, the two sides of the bottom end of the data cable squeeze the limiting plate 10, so that the limiting plate 10 moves toward the inside of the installation groove and pushes the first rack 11 to move, so that the gear 12 drives the rotating rod 13 to rotate, and the second rack 14 drives the clamping plate 15 to move, and the connecting spring is stretched, so that the clamping plate 15 moves to one side of the limiting plate 10 and presses against the limiting plate 10. The limiting plate 10 extends in the vertical direction and is a flexible plate, which can produce slight deformation under the action of the squeezing force, so that the limiting plate 10 limits the two sides of the data cable, which is convenient for the protective block 6 to drive the data cable to move and connect with the connecting port 2, thereby improving the stability and accuracy of the connection.

[0026] like Figure 3 to Figure 4 As shown, movable openings are opened on the inner walls on both sides of the two protective blocks 6, and the limiting plate 10 is located at the movable opening. Both sides of the first rack 11 and the second rack 14 are slidably connected to the inner wall of the mounting groove. The first rack 11 and the second rack 14 are arranged parallel to each other and perpendicular to the limiting plate 10. Both sides of the rotating rod 13 are rotatably connected to the inner wall of the mounting groove. The clamping plate 15 is located on one side of the limiting plate 10, and one end of the connecting spring is fixedly installed on the inner wall of the mounting groove.

[0027] The movable opening facilitates the movement of the limiting plate 10 into the installation groove to push the first rack 11 to move, so that the gear 12 drives the rotating rod 13 to rotate along the inner wall of the installation groove, thereby improving the stability of the rotation of the gear 12, and the second rack 14 drives the clamping plate 15 to move to the side of the limiting plate 10, clamping the limiting plate 10, thereby improving the stability of the limiting plate 10.

[0028] like Figure 5 , Figure 8 , Fig. 9As shown, a protective plate 16 is provided on the top of each of the two protective blocks 6, and the protective plate 16 is symmetrically arranged around the center of the protective block 6. A second electric push rod 17 is vertically hinged at the bottom of one end of the protective plate 16, and two first movable grooves are provided on the side of the protective plate 16 away from the second electric push rod 17. A third electric push rod 26 is fixedly installed in each of the two first movable grooves, a second baffle 18 is fixedly installed on one side of the third electric push rod 26 in the upper first movable groove, and a clamping block 19 is fixedly installed on one side of the third electric push rod 26 in the lower first movable groove, connecting grooves are provided on both sides of the clamping block 19, a telescopic rod 20 is fixedly installed inside the connecting groove, a first magnetic block 21 is fixedly installed on one side of the telescopic rod 20, and the first magnetic blocks 21 are magnetically connected.

[0029] Start the third electric push rod 26 above to push the second baffle 18 to the first movable groove above the protective plate 16, rotate the protective plate 16 to expose the middle part of the protective block 6, and then insert the connector of the data line into the middle part of the protective block 6 and limit it through the limiting plate 10, and drive the protective block 6 to move into the groove through the first electric push rod 5, so that the data line is plugged into the connecting port 2, and then rotate the protective plate 16 to its original position, and drive the protective plate 16 to move upward by starting the second electric push rod 17, so that the protective plate 16 moves above the data line, and push the card block 19 in the first movable groove through the third electric push rod 26 below so that one side of it is fitted with the outside of the data line. At the same time, through the mutual adsorption of two first magnetic blocks 21 arranged opposite to each other, the telescopic rod 20 is extended to limit the two sides of the data line, so that the data line and the data line plug-in end remain vertical, further improving the stability of the data line connection, and preventing the data line and the data line plug-in end from bending and breaking, which affects the use.

[0030] like Figures 8 to 10 As shown, a movable opening is provided on the top of the two protective blocks 6, one end of the protective plate 16 is located at the top of the movable opening, a fixed plate is fixedly installed on the bottom of the second electric push rod 17, and the fixed plate is fixedly installed on the inner wall of the installation groove, the second baffle 18 is located on the top of the protective block 6 and one side of it is in contact with it, an arc groove is provided on one side of the clamping block 19, the telescopic rod 20 and the first magnetic block 21 are both located on both sides of the arc groove, the clamping block 19 is located inside the first movable groove below, a sliding groove is provided on one side of the protective plate 16, and a slider is slidably connected inside the sliding groove, one side of the slider is fixedly installed with the clamping block 19, and a movable block 22 is fixedly installed on the other side, and the movable block 22 is located on one side of the sliding groove.

[0031] The second electric push rod 17 passes through the moving opening to drive the protective plate 16 to move upward, so that the protective plate 16 can move upward, and the data line is limited by the card block 19. The second electric push rod 17 is conveniently installed in the installation groove through the fixing plate. When not in use, the top of the protective block 6 is blocked by the second baffle 18 to prevent dust from entering the interior of the connecting port 2 and affecting the connection and use of the data line. When the data line needs to be plugged in, the third electric push rod 26 moves the second baffle 18 to the first moving groove above, so that the protective plate 16 is rotated ninety degrees to move the protective plate 16 upward. The middle part of the guard plate 16 is exposed, and then the data line is inserted into the protection block 6 and plugged into the connection port 2. When the plugging is completed, the guard plate 16 is rotated to its original position, and the third electric push rod 26 pushes the movable block 22 to drive the slider to move along the slide groove, so that the slider drives the card block 19 to move along the inner wall of the first movable groove to the outside of the guard plate 16, and the arc-shaped groove inner wall of the card block 19 is fitted with the outside of the data line, and through the action of the telescopic rod 20 and the first magnetic block 21, the card block 19 limits the data line, thereby improving the stability of the data line connection and further preventing movement caused by collision, which affects the use.

[0032] like Figures 8 to 10 As shown, second movable grooves are provided on the tops of the two protective blocks 6 and on both sides of the bottom of the protective plate 16, and a movable plate 23 is slidably connected to the inner wall of the second movable groove. Second magnetic blocks 24 are fixedly installed at both ends of the top of the movable plate 23, and third magnetic blocks 25 are fixedly installed on both sides of the bottom of the movable plate 23. The second magnetic block 24 and the third magnetic block 25 are magnetically connected.

[0033] The movable plate 23 is installed through the second movable groove. When the data cable is plugged into the connecting port 2, the second electric push rod 17 is started to drive the protective plate 16 to move upward. Through the action of the second magnetic block 24 and the third magnetic block 25, the protective plate 16 drives the movable plate 23 to move upward, so that the movable plate 23 protects both sides of the data cable on the top of the chassis shell 1, further preventing the data cable from being squeezed and collided, thereby facilitating to increase the service life.

[0034] Working principle: When in use, press the power button to start the chassis, and start the first electric push rod 5 through the control button to drive the protective block 6 to move upward, so that the protective block 6 moves to the top of the chassis shell 1, and then the third electric push rod 26 in the upper second moving groove is used to move the second baffle 18 to the inside of the upper first moving groove, and the protective plate 16 is rotated ninety degrees to expose the middle part of the protective plate 16, and the bottom end of the data line is inserted into the inside of the protective block 6. At the same time, the two sides of the bottom end of the data line squeeze the limiting plate 10, so that the limiting plate 10 moves into the installation groove, and pushes the first rack 11 to move, so that the gear 12 drives the rotating rod 13 to rotate along the inner wall of the installation groove, and the second rack 14 drives the clamping plate 15 to move, and the connecting spring is stretched, so that the clamping plate 15 moves to one side of the limiting plate 10, and presses the limiting plate 10, so that the limiting plate 10 limits the two sides of the data line. When the limiting plate 10 limits the data line inside the protective block 6, the first electric push rod 5 drives the protective block 6 to move downward into the groove. At the same time, the protective block 6 drives the internally limited data line downward when it moves, and the bottom connector of the data line is connected with the connecting port 2. When the earphone needs to be plugged in, the first baffle 9 is rotated to expose the earphone jack 3. By pressing the control button, the electric telescopic plate 7 drives the telescopic block 8 to move upward, so that the electric telescopic plate 7 and the telescopic block 8 move to the top of the chassis shell 1 to shield and protect the outside of the earphone line, separate the earphone line from the mobile phone data line, and no entanglement occurs. When only one earphone line is plugged in, the telescopic block 8 on one side is moved so that the telescopic block 8 pushes the telescopic block 8 on the other side to contract. The telescopic block 8 moves to the side where the earphone line is plugged in, and the earphone line is protected by the two contracted telescopic blocks 8.

[0035] After the data cable is plugged into the connection port 2, the protective plate 16 is rotated to both sides of the data cable in a horizontal state, and the second electric push rod 17 is started to pass through the movable port to drive the protective plate 16 to move upward. Through the action of the second magnetic block 24 and the third magnetic block 25, the protective plate 16 drives the movable plate 23 to move upward, so that the movable plate 23 protects both sides of the data cable on the top of the chassis shell 1, and then the movable block 22 is moved to drive the slider to move along the slide groove, so that the slider drives the card block 19 to move along the inner wall of the first movable groove to the outside of the protective plate 16, and the arc-shaped groove inner wall of the card block 19 is fitted with the outside of the data cable, and through the action of the telescopic rod 20 and the first magnetic block 21, the card block 19 limits the data cable, thereby improving the stability of the data cable connection and further preventing movement caused by collision, thereby affecting use.

[0036] The present invention also provides a computer, comprising the chassis as described above.
