Description

Technical Field

[0001] This utility model relates to the field of seat installation, and in particular to a quick-lock structure for a track seat and a track seat. Background Technology

[0002] Ship seats are essential equipment on board. Depending on the different spatial layouts of the cabin, the needs of various scenarios, and individual differences among personnel, the positions and spacing of the seats on board need to be adjusted. Currently available adjustment methods mostly involve fixing the seats in fixed positions with bolts. This results in drawbacks such as time-consuming and labor-intensive adjustments, limited adjustment range, and potential damage to the cabin floor. Some adjustable seat structures rely solely on friction for locking. In the turbulent conditions at sea, the seats are subjected to significant translational impacts, which can easily cause the friction lock to fail, leading to accidents. Furthermore, the locking structure is often too large, making it easily accessible to non-staff members and posing other unnecessary risks. Utility Model Content

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0028] See Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, a track seat includes two parallel grooved linear slide rails, a seat body, a quick-lock structure, and a sliding base plate. The seat body is fixedly installed at the center of the upper surface of the sliding base plate. Quick-lock structures are fixedly installed on the sliding base plates on both sides of the seat body. The positioning slider and anti-disengagement locking slider of the quick-lock structure are movably locked in the guide groove of the grooved linear slide rail. Slide guide blocks are also provided near the two ends of the quick-lock structure on the lower surface of the sliding base plate. The slide guide blocks are slidably connected to the guide groove.

[0029] See Figure 7-8 As shown, in the locked state, the quick-lock structure has the following characteristics: the positioning slider is tightly fitted with the inner wall of the guide groove to stop the seat, and the anti-disengagement locking slider is engaged in the guide groove to lock and connect with the grooved linear slide rail.

[0030] See Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the quick-lock structure includes: an integral fixing base, an anti-detachment base plate, a positioning flip cover, and an anti-detachment flip cover. The anti-detachment base plate is fixedly installed in the integral fixing base by screws. The positioning flip cover is rotatably connected to the positioning anti-detachment base plate via a positioning pin. One or both sides of the positioning flip cover are provided with positioning flip shafts, which are connected to offset positioning tension springs. The positioning anti-detachment base plate is provided with a number of positioning fixing pins matching the number of positioning flip shafts. The other end of the offset positioning tension spring is connected to the positioning fixing pin. The anti-detachment flip cover is rotatably connected to one end of the positioning anti-detachment base plate via an anti-detachment pin. The positioning flip cover is provided with a first protrusion, and the anti-detachment flip cover is provided with a second protrusion. The anti-detachment base plate has a first connecting groove and a second groove. Both sides of the first groove and the second groove have movable openings. Two positioning sliders are movably mounted in the first groove. The two positioning sliders can move vertically along the guide rail in the first groove. When the two positioning sliders are at their farthest distance, the two ends of the two positioning sliders will extend out from the movable opening, and the two positioning sliders will not fall out of the first groove. A supporting elastic element is provided between the two positioning sliders. The second groove movably mounts two anti-detachment locking sliders with similar structure and movement to the positioning sliders. A supporting elastic element is also provided between the anti-detachment locking sliders.

[0031] The lower ends of the two positioning sliders are provided with inclined guide surfaces on their back sides, and the lower ends of the two anti-disengagement locking sliders are also provided with inclined guide surfaces on their back sides.

[0032] When the quick-lock structure is connected to the slide rail, the positioning slider can slide and retract relatively close to each other when pressure is applied through the inclined guide surface. In its natural state, it is supported by the elastic element of the slider and slides open. When it is opened, the positioning flip cover contacts the positioning slider under the action of deflection force. When the gap between the two positioning sliders reaches the limit, the plug on the positioning flip cover will fill the gap, realizing the positioning and locking function.

[0033] The positioning anti-detachment base plate has a sliding groove, in which an elastic lock is slidably installed. A return spring is provided between the elastic lock and the side wall of the sliding groove, and the elastic lock is movably engaged with the anti-detachment flip cover.

[0034] The end of the elastic lock away from the spring is provided with a locking part, which is provided with a locking protrusion. The anti-detachment flip cover is also provided with a locking protrusion on the connecting surface with the locking part, or the anti-detachment flip cover is provided with a locking groove on the connecting surface with the locking part. The locking part is movably locked with the locking protrusion or locking groove of the anti-detachment flip cover through the locking protrusion.

[0035] When the spring lock needs to be unlocked, press the part of the spring lock that extends out of the slide to compress the return spring and thus unlock it. The anti-slip flip cover can be lifted when it is unlocked.

[0036] When the positioning flip cover is engaged, the first protrusion inserts between the two positioning sliders to limit their movement.

[0037] The offset positioning tension spring provides a closing holding tension when the positioning flip cover is in the closed state, and provides a back-flipping tension to open the positioning flip cover when the positioning flip cover is in the open state.

[0038] When the anti-detachment flip cover is closed, the second protrusion is positioned between the two anti-detachment locking sliders to limit and lock the anti-detachment locking sliders.

[0039] When closed, the anti-detachment flip cover covers the anti-detachment base plate and the positioning flip cover inside the anti-detachment flip cover and the overall fixing base.

[0040] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
