[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Example 1:

[0024] Combination Figure 1-4 As shown, this embodiment provides an aircraft seat connection device, including: a main body mechanism 100.

[0025] The main body 100 includes a base 110, a drive component 120 installed in the inner cavity of the base 110, a movable seat 130 slidably disposed on the top of the base 110, a threaded sleeve 140 fixed to the bottom of the movable seat 130 and extending into the base 110, a seat leg 150 fitted on the top of the movable seat 130, a fixing plate 160 disposed on both sides of the seat leg 150 and passing through the seat leg 150, and a bolt 170 passing through the fixing plate 160 and engaging with the movable seat 130.

[0026] The base 110 has a trapezoidal cross-section and is fixed to the aircraft floor plate with screws. Similar to the installation of other components, a groove 111 is opened at the top of the base 110. The drive component 120 includes a threaded rod 121 rotatably installed in the groove 111 and a motor 122 fixed to one side of the base 110 with its shaft fixedly connected to the threaded rod 121. At the same time, a threaded sleeve 140 is fitted into the groove 111, and the threaded rod 121 passes through the threaded sleeve 140 and meshes with the threaded sleeve 140. The top of the threaded sleeve 140 extends out of the groove 111 and is fixedly connected to the movable seat 130. When the motor 122 is started, it drives the threaded rod 121 to rotate. The rotation of the threaded rod 121 drives the threaded sleeve 140 to move. The movement of the threaded sleeve 140 drives the movable seat 130 to move, thereby moving the entire aircraft seat and adjusting the fore-and-aft position of the aircraft seat.

[0027] The movable seat 130 is used to fix the seat leg 150. The two sides of the movable seat 130 are set with slopes. The top of the movable seat 130 has multiple rectangular slots 131. The bottom of the seat leg 150 is fitted into the rectangular slots 131 to ensure the stability of the seat leg 150 base.

[0028] The fixing plate 160 is used to fix the seat leg 150 to the movable seat 130. It includes an inclined clamping plate 161 set on one side of the movable seat 130 and a plurality of inserts 162 fixed on the inner side of the inclined clamping plate 161. One end of the inclined clamping plate 161 is close to the top of the seat leg 150, and the other end is close to the inclined surface of the movable seat 130. A threaded hole 133 is opened on the inclined surface of the movable seat 130, and a second round hole 1611 is opened on one side of the inclined clamping plate 161. The bolt 170 passes through the second round hole 1611 and engages in the threaded hole 133. With this setting, the worker can turn the bolt 170 at an angle during installation, which provides more operating space and makes it more convenient to tighten the bolt 170, further increasing the convenience of aircraft seat installation.

[0029] In addition, multiple slots 132 are arranged in an array on the inner bottom wall of the rectangular groove 131, and multiple first round holes 151 are arranged in an array at the bottom end of the seat leg 150. The insert 162 passes through the first round hole 151 and fits into the slot 132, further increasing the stability of the fixation between the seat leg 150 and the movable seat 130.

[0030] The working principle and usage process of this utility model are as follows: In use, the bottom end of the seat leg 150 is embedded into the rectangular groove 131 on the movable seat 130, and the inclined plate 161 is fitted onto one side of the seat leg 150, so that the insert 162 on the inclined plate 161 passes through the first round hole 151 on the seat leg 150 and is fitted into the slot 132. After completion, the bolt 170 is passed through the second round hole 1611 on the inclined plate 161 and engaged in the threaded hole 133 on the movable seat 130, thus completing the fixation of the seat leg 150. When it is necessary to adjust the front and rear position of the seat, the motor 122 is started to drive the threaded rod 121 to rotate. The rotation of the threaded rod 121 drives the threaded sleeve 140 to move. The movement of the threaded sleeve 140 drives the movable seat 130 to move. The movement of the movable seat 130 drives the entire aircraft seat to adjust its front and rear position through the seat leg 150.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
