Technical Field

[0001] The utility model relates to the technical field of aircraft plate installation, in particular to an aircraft interior plate installation device. Background Technique

[0002] An aircraft refers to an aircraft that has wings and one or more engines and is driven forward by its own power and can fly in the atmosphere with its own density greater than that of air. When people need to travel long distances, they sometimes choose to travel by plane;

[0003] There are various decorative plates inside the aircraft, and the commonly used one by people is generally the table board on the seat. At present, when installing the table board of the aircraft, it is generally installed by multiple screws. After long-term use, the screws are likely to become loose. And when the table board needs to be repaired and replaced after long-term use, the installation method using multiple screws takes a lot of time for both disassembly and assembly, affecting the repair and replacement efficiency. For this reason, we propose an aircraft interior plate installation device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aircraft interior plate installation device.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an aircraft interior plate installation device, including a table board, and further including an installation strip and two installation rods. The installation strip is arranged on the right side of the table board. The installation rods are horizontally and fixedly arranged on the left side of the installation strip and are symmetrically distributed front and back. Two installation slots for the installation rods to slide and insert are opened at the right end of the table board. At one end of the opposite sides of the installation slots away from the installation strip, strip-shaped slots are opened. Both of the two strip-shaped slots are square. Clamping plates are slidably arranged in both of the two strip-shaped slots. A group of clamping teeth are fixedly arranged on the opposite sides of both of the two clamping plates. A group of tooth slots for the clamping teeth to slide and engage are opened at one end of the opposite sides of both of the two installation rods away from the installation strip. A longitudinally arranged bidirectional threaded rod is rotatably arranged inside the table board through a first bearing. The front and rear ends of the bidirectional threaded rod are respectively threadedly connected to the two clamping plates, and the front and rear ends of the bidirectional threaded rod are respectively rotatably connected to the bottoms of the two strip-shaped slots through second bearings. A groove is opened on the front side of the table board. The front end of the bidirectional threaded rod extends into the groove and is fixedly connected to a driving block. A limiting plate is also slidably arranged inside the groove. A guiding and limiting mechanism is arranged between the limiting plate and the driving block. An elastic mechanism for applying an elastic force to the limiting plate to the right is arranged inside the groove.

[0006] As a further solution of the present utility model: The one-way limiting mechanism includes a set of first ratchet teeth and a set of second ratchet teeth. A plurality of the first ratchet teeth in the set are fixedly arranged on the circumferential side wall of the driving block and are evenly distributed in a ring shape. The right side of the limiting plate is arranged in an arc shape. A plurality of the second ratchet teeth in the set are fixedly arranged on the right arc surface of the limiting plate and can be engaged with the first ratchet teeth.

[0007] As a further solution of the present utility model: The elastic mechanism includes a slider, a round rod and a spring. A sliding groove is opened at the bottom of the groove. The slider is slidably arranged in the sliding groove, and the slider is fixedly connected with the limiting plate. The round rod is horizontally fixedly arranged in the sliding groove. The slider is slidably sleeved with the round rod through a round hole. The spring is fixedly arranged on the left side of the slider and is movably sleeved with the round rod.

[0008] As a further solution of the present utility model: The surface of the limiting plate is provided with anti-slip lines.

[0009] As a further solution of the present utility model: Longitudinally arranged guide grooves are opened at the bottoms of the two strip-shaped grooves. Guide rods are slidably arranged in the two guide grooves respectively. The two guide rods are fixedly connected with opposite sides of the two clamping plates respectively.

[0010] As a further solution of the present utility model: The end faces of the two mounting rods and the two mounting grooves are both circularly arranged.

[0011] Adopting the above technical solution, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When installing the table board of the present utility model, directly insert the two mounting rods into the two mounting grooves, and then drive the bidirectional threaded rod to rotate forward by rotating the driving block. Since the limiting plate is slidably arranged in the groove through the elastic mechanism, it will not affect the forward rotation of the driving block. The bidirectional threaded rod rotates to drive the two clamping plates to move relatively. The two clamping plates drive the two groups of ratchet teeth to move until the two groups of ratchet teeth are respectively clamped into the two groups of tooth grooves, so that the two mounting rods and the table board are fixed to each other, thus completing the installation of the table board. At this time, under the thrust of the spring and the slider, the limiting plate will drive the second ratchet teeth to engage with the first ratchet teeth, making the driving block and the bidirectional threaded rod unable to rotate reversely, thus avoiding loosening. And when disassembling, pull the limiting plate to the left to separate the first ratchet teeth and the second ratchet teeth, and then rotate the driving block reversely to drive the bidirectional threaded rod to rotate reversely, so that the two groups of ratchet teeth are removed from the two groups of tooth grooves, so that the table board can be disassembled;

[0013] 2. By providing two guiding rods and two guiding grooves, the present utility model can make the relative movement of the two clamping plates more stable, and make the engagement of the two sets of teeth into the tooth grooves more stable. By setting the end faces of the two mounting rods and two mounting grooves to be circular, the two mounting rods can be inserted into the two mounting grooves more conveniently, avoiding jamming during insertion.

[0014] Other advantages, objectives and features of the present utility model will be elaborated to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0022] Please refer to the attached Figure 1 - attached Figure 4, a mounting device for aircraft interior panel of the present utility model includes a table board 1, and further includes a mounting strip 2 and two mounting rods 3. The mounting strip 2 is arranged on the right side of the table board 1. The mounting rods 3 are horizontally and fixedly arranged on the left side of the mounting strip 2 and are symmetrically distributed front and back. Two mounting slots for the mounting rods 3 to slide and insert are provided at the right end of the table board 1. Bar-shaped slots are provided at one end of the opposite sides of the mounting slots away from the mounting strip 2. Both of the two bar-shaped slots are square. A clamping plate 4 is slidably arranged in each of the two bar-shaped slots. A set of clamping teeth 5 are fixedly arranged on the opposite sides of the two clamping plates 4. A set of tooth slots for the clamping teeth 5 to slide and engage are provided at one end of the opposite sides of the two mounting rods 3 away from the mounting strip 2. A longitudinally arranged bidirectional threaded rod 6 is rotatably arranged inside the table board 1 through a first bearing. The front and rear ends of the bidirectional threaded rod 6 are respectively threadedly connected to the two clamping plates 4, and the front and rear ends of the bidirectional threaded rod 6 are respectively rotatably connected to the bottoms of the two bar-shaped slots through second bearings. A groove is provided on the front side of the table board 1. The front end of the bidirectional threaded rod 6 extends into the groove and is fixedly connected with a driving block 7. A cross-shaped slot is arranged at one end of the driving block 7 away from the bidirectional threaded rod 6, which is convenient for using a cross screwdriver to screw the driving block 7. A limiting plate 8 is also slidably arranged inside the groove. A guiding and limiting mechanism is arranged between the limiting plate 8 and the driving block 7. An elastic mechanism for applying an elastic force to the limiting plate 8 to the right is arranged inside the groove.

[0023] In an embodiment of the present utility model: The unidirectional limiting mechanism includes a set of first ratchet teeth 9 and a set of second ratchet teeth 10. A plurality of the first ratchet teeth 9 in a set are all fixedly arranged on the circumferential side wall of the driving block 7 and are evenly distributed in a ring. The right side of the limiting plate 8 is arc-shaped. A plurality of the second ratchet teeth 10 in a set are all fixedly arranged on the right arc-shaped surface of the limiting plate 8 and can engage with the first ratchet teeth 9.

[0024] In an embodiment of the present utility model: The elastic mechanism includes a slider 11, a round rod 12 and a spring 13. A chute is provided at the bottom of the groove. The slider 11 is slidably arranged in the chute, and the slider 11 is fixedly connected with the limiting plate 8. The round rod 12 is horizontally and fixedly arranged in the chute. The slider 11 is slidably sleeved with the slider 11 through a round hole. The spring 13 is fixedly arranged on the left side of the slider 11 and is movably sleeved with the round rod 12.

[0025] When the driving block 7 drives the first ratchet teeth 9 to rotate forward, it will push the limiting plate 8 and the second ratchet teeth 10 to slide leftward, and the driving block 7 can rotate normally. When the driving block 7 rotates reversely, the second ratchet teeth 10 will block the first ratchet teeth 9, making the driving block 7 unable to rotate reversely.

[0026] In an embodiment of the present utility model: Anti-slip lines are provided on the surface of the limiting plate 8, which is convenient for people to push the limiting plate 8 to slide leftward.

[0027] In one embodiment of the utility model: the bottom of the two strip grooves are provided with longitudinal guide grooves, and guide rods 14 are slidably arranged in the two guide grooves. The two guide rods 14 are respectively fixedly connected to the opposite sides of the two clamping plates 4, which can make the two clamping plates 4 more stable when moving relative to each other, and make the two groups of clamping teeth 5 more stable when they are clamped in the tooth grooves.

[0028] In one embodiment of the present invention, the end faces of the two mounting rods 3 and the two mounting grooves are both circular, so that the two mounting rods 3 can be inserted into the two mounting grooves more conveniently to avoid jamming during insertion.

[0029] Working principle:

[0030] When the table board 1 is installed, the two mounting rods 3 are directly inserted into the two mounting grooves, and then the two-way threaded rod 6 is driven to rotate forward by rotating the driving block 7. Since the limit plate 8 is slidably arranged in the groove by an elastic mechanism, the forward rotation of the driving block 7 will not be affected. The rotation of the two-way threaded rod 6 drives the two clamping plates 4 to move relative to each other, and the two clamping plates 4 drive the two sets of clamping teeth 5 to move until the two sets of clamping teeth 5 are respectively inserted into the two sets of tooth grooves, so that the two mounting rods 3 and the table board 1 are fixed to each other, thereby completing the installation of the table board 1. At this time, the limit plate 8, under the thrust of the spring 13 and the slider 11, will drive the second ratchet 10 to engage with the first ratchet 9, so that the driving block 7 and the two-way threaded rod 6 cannot rotate in the opposite direction, thereby avoiding loosening. When disassembling, the limit plate 8 is pulled to the left to separate the first ratchet 9 and the second ratchet 10, and then the driving block 7 is rotated in the opposite direction to drive the two-way threaded rod 6 to rotate in the opposite direction, so that the two sets of clamping teeth 5 are removed from the two sets of tooth grooves, so that the table board 1 can be disassembled. At this point, the entire work flow is completed.
