Description

Technical Field

[0001] This utility model relates to the field of tabletop button technology, and in particular to a tabletop button. Background Technology

[0002] In aircraft seats, high-speed rail seats, and public waiting area seats, folding tables are core functional components, and the reliability of their unfolding and positioning directly affects the user experience.

[0003] Existing foldable tables on the back of seats are usually limited by a rotating knob. However, the vehicle body vibrates during movement, and frequent vibrations can cause the knob to rotate by a certain angle, thus removing the knob from the table and allowing the table to open automatically, which affects the experience of rear passengers. To solve the above problem, this application proposes a table button. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tabletop button. By making the button height-adjustable, it can limit the tabletop and prevent the tabletop from automatically flipping due to the button's rotation, thus providing excellent limiting effect on the tabletop.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tabletop button includes a mounting block, a button body at the bottom of the mounting block, a lifting mechanism between the mounting block and the button body, the lifting mechanism including two cross rods fixedly connected to the top of the button body, two cross slots at the bottom of the mounting block, the two cross rods being inserted into corresponding cross slots, two limiting plates fixedly connected to the top of the button body, two limiting grooves at the bottom of the mounting block, the two limiting plates being inserted into corresponding limiting grooves, and a tabletop body at the rear of the button body.

[0007] Preferably, the bottom of the mounting block has a receiving groove that mates with the button body.

[0008] Preferably, a protective layer is provided at the bottom of the button body, and the protective layer is made of rubber.

[0009] Preferably, the side wall of the limiting plate is fixedly connected with a protruding strip, the mounting block has a groove, the limiting groove is connected to the groove, and the protruding strip is located in the groove and slidably connected to its inner wall.

[0010] Preferably, two guide plates are fixedly connected to the top of the button body, and two guide grooves are opened at the bottom of the mounting block, with the two guide plates respectively inserted into the corresponding guide grooves.

[0011] Preferably, each of the cross rods is fitted with a spring on its outer wall, and the two ends of each spring are fixedly connected to the mounting block and the button body, respectively.

[0012] Preferably, the distance between the rear end of the button body and the rear end of the mounting block is greater than the thickness of the tabletop body.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] When the user presses the button, the spring compresses and retracts the button into the mounting block, at which point the tabletop can be freely flipped to a horizontal position; after the button is released, the spring returns to its original position, and the button protrudes to form a mechanical limit on the edge of the tabletop.

[0015] In summary, by making the buttons height-adjustable, the tabletop can be limited, preventing the tabletop from automatically flipping due to button rotation, thus providing excellent limiting effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5A tabletop button includes a mounting block 1, which is fixedly mounted on the back of a seat. The bottom of the mounting block 1 has a button body 2, and the bottom of the mounting block 1 has a receiving groove that mates with the button body 2. When the button body 2 retracts into the receiving groove, the bottom of the button body 2 is flush with the bottom of the mounting block 1. The bottom of the button body 2 has a protective layer made of rubber. The rubber protective layer on the bottom of the button body 2 can increase the tactile feel when contacted.

[0024] Two guide plates 3 are fixedly connected to the top of the button body 2. Two guide grooves 7 are opened at the bottom of the mounting block 1. The two guide plates 3 are respectively inserted into the corresponding guide grooves 7. A lifting mechanism is provided between the mounting block 1 and the button body 2. The lifting mechanism includes two cross rods 4 set on the top of the button body 2 and fixedly connected to it. Two cross grooves 8 are opened at the bottom of the mounting block 1. The two cross rods 4 are respectively inserted into the corresponding cross grooves 8. A spring 9 is sleeved on the outer wall of each cross rod 4. The two ends of each spring 9 are fixedly connected to the mounting block 1 and the button body 2 respectively. The spring 9 can make the button body 2 protrude from the mounting block 1 and limit the table body 12. In this application, the spring 9 has a large elastic force to prevent the button body 2 from moving freely up and down due to vibration.

[0025] Two limiting plates 5 are fixedly connected to the top of the button body 2. Two limiting grooves 10 are opened at the bottom of the mounting block 1. The two limiting plates 5 are respectively inserted into the corresponding limiting grooves 10. A protruding strip 6 is fixedly connected to the side wall of the limiting plate 5. A groove 11 is opened in the mounting block 1. The limiting groove 10 is connected to the groove 11. The protruding strip 6 is located in the groove 11 and is slidably connected to its inner wall. The distance that the protruding strip 6 slides in the groove 11 is the distance that the button body 2 moves.

[0026] The button body 2 has a table body 12 on its rear side. The table body 12 is installed at the rear end of the seat and is rotatably connected to the seat. The distance between the rear end of the button body 2 and the rear end of the mounting block 1 is greater than the thickness of the table body 12. The two ends of the table body 12 can be abutted against each other by the cooperation between the button body 2 and the seat, thus limiting the position of the table body 12.

[0027] In this invention, the mounting block 1 is installed on the back of the front seat, and the table body 12 is installed on the back of the front seat and located below the mounting block 1. When the user needs to use the table body 12 for dining, the user presses the button body 2 to move it towards the mounting block 1. The movement of the button body 2 causes the guide plate 3 to slide in the guide groove 7, the cross rod 4 to slide in the cross groove 8, and the spring 9 to compress. The limiting plate 5 slides in the limiting groove 10, and the protrusion 6 slides in the groove 11, causing the button body 2 to retract into the receiving groove (at this time, the bottom of the button body 2 is flush with the bottom of the mounting block 1). The user can then flip the table body 12 so that it changes from being parallel to the seat to being perpendicular to the seat, thus completing the horizontal positioning of the table body 12. The tabletop body 12 is designed to support food for convenient dining. After use, the user presses the button body 2 again to move it towards the mounting block 1. During this process, the spring 9 is compressed until the button body 2 retracts into the receiving groove. At this time, the bottom of the button body 2 is flush with the bottom of the mounting block 1. The user flips the tabletop body 12 to make it parallel to the seat. Finally, the user releases the button body 2, and under the action of the spring 9, the button body 2 moves away from the mounting block 1, making the button body 2 protrude from the bottom of the mounting block 1. The rear end of the button body 2 and the seat limit the two ends of the tabletop body 12, thereby fixing the tabletop body 12 and preventing it from rotating at will. The range of the sliding of the protrusion 6 in the groove 11 is the range of movement of the button body 2.

[0028] This invention solves the problem in the prior art where vibrations occur during vehicle movement, causing the rotary knob to rotate at a certain angle and thus no longer limit the table, allowing the table to open automatically and affecting the experience of rear passengers.
