They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0031] Please refer to Figure 1 This embodiment provides a T-shaped handle structure 100, which is simple to operate, easy to use, and can be used in a relatively small space.

[0032] It should be noted that, in the embodiment of the present invention, the T-shaped handle structure 100 can be applied to an aircraft, and can be used in a spacecraft environment where the use space is relatively small, and has the characteristic of easy operation.

[0033] Please refer to Figure 2 In an embodiment of the present invention, the T-shaped handle structure 100 includes a lock disk 110, a handle member 120, an elastic member 130 and a locking assembly 140. The elastic member 130 is supported between the handle member 120 and the lock disk 110. The locking assembly 140 is arranged on the lock disk 110 for locking or unlocking the handle member 120. The elastic member 130 is used to extend the handle member 120 relative to the lock disk 110 when the handle member 120 is unlocked.

[0034] It can be understood that the locking assembly 140 is used to lock or unlock the handle 120, and the handle 120 and the lock plate 110 can move relative to each other. When the locking assembly 140 unlocks the handle 120, the handle 120 can move relative to the lock plate 110. At this time, the elastic member 130 stretches, and the elastic force acts on the handle 120 to make it extend relative to the lock plate 110. The extended part of the handle 120 can handle the operation under the current working condition.

[0035] Please refer to Figure 1 , Figure 5 and Figure 6 When the T-shaped handle of the embodiment of the present invention is used, the handle member 120 is unlocked by the locking assembly 140 disposed on the lock disk 110. At this time, the handle member 120 can move relative to the lock disk 110 and extend relative to the lock disk 110 under the action of the elastic member 130. The extended handle can realize the operation under the current working condition.

[0036] It should be understood that in the above-mentioned use process, the position of the operator is not limited, and the operator can be located on either side of the lock disk 110. In other words, the operator can operate on both sides of the lock disk 110, and the operation is convenient, which is suitable for narrow areas and spaces where it is inconvenient for people to move.

[0037] In an optional embodiment, the above-mentioned locking assembly 140 may include a pressing member 141, a pressing spring 142 and a locking member 143. The pressing spring 142 is supported between the pressing member 141 and the locking disk 110. The locking member 143 is rotatably arranged on the locking disk 110 for locking or unlocking the handle member 120. The pressing member 141 is transmission-connected to the locking member 143 for driving the locking member 143 to rotate relative to the locking disk 110.

[0038] It should be noted that when unlocking, the pressing member 141 is subjected to force to compress the pressing spring 142, and the pressing member 141 is in transmission connection with the locking member 143, so that the locking member 143 can rotate relative to the lock plate 110 when subjected to an external force, thereby unlocking the handle member 120. After the external force is released, the pressing member 141 is displaced to the initial position under the elastic force of the pressing spring 142. In other words, the pressing spring 142 is used to reset the pressing member 141, the pressing member 141 is used to drive the locking member 143 to move, and the locking member 143 is used to lock the handle member 120.

[0039] Please refer to Figure 3 Further, the above-mentioned locking member 143 may include a first extension portion 1431, a second extension portion 1432 and a locking portion 1433 connected in sequence, the first extension portion 1431 is rotatably connected to the pressing member 141, the second extension portion 1432 is rotatably connected to the locking disk 110, and the locking portion 1433 is used to clamp the handle member 120 to lock the handle member 120, and the locking portion 1433 is also used to release the clamping with the handle member 120 to unlock the handle member 120.

[0040] Optionally, the first extension portion 1431 , the second extension portion 1432 and the locking portion 1433 are sequentially connected to form a transverse Z-shape, so as to facilitate locking or unlocking the handle 120 by pressing.

[0041] Furthermore, the locking portion 1433 may be provided with a guide surface 1434 and a holding surface 1435 connected to each other, wherein the guide surface 1434 is inclined relative to the holding surface 1435, and the guide surface 1434 has a relatively lower end and a relatively higher end, and the holding surface 1435 is located at the higher end.

[0042] It is understandable that the guide surface 1434 is used to guide the handle 120 when the handle 120 is retracted back to the lock plate 110, so that the handle 120 can be retracted smoothly. After retracting to the right position, the handle 120 is clamped by the clamping surface 1435 to achieve locking of the handle 120. The handle 120 may be provided with a clamping protrusion or a clamping portion that is clamped on the clamping surface 1435.

[0043] Please continue to refer to Figure 2 Furthermore, the above-mentioned pressing member 141 may include a pressing portion 1411 and a connecting portion 1412 that are connected to each other. The lock disk 110 is provided with a button groove 112. The pressing portion 1411 can slide along the side wall of the button groove 112. The pressing spring 142 is sleeved on the connecting portion 1412 and is supported between the pressing portion 1411 and the bottom wall of the button groove 112. The connecting portion 1412 extends out of the button groove 112 and is rotatably connected to the first extension portion 1431.

[0044] It should be noted that when the pressing member 141 is subjected to external force, the pressing member 141 slides relative to the button slot 112 and compresses the pressing spring 142 therebetween. The other end of the pressing member 141 transmits the motion to the first extension portion 1431 and drives the first extension portion 1431, the second extension portion 1432 and the locking portion 1433 to rotate. The locking portion 1433 rotates to release the clamping state with the handle 120, thereby unlocking the handle 120.

[0045] In an optional embodiment, the handle member 120 may include a handle body 121 and a handle shaft 122 connected to each other in a T-shape, the elastic member 130 is supported between the handle shaft 122 and the lock disk 110, the locking assembly 140 is used to lock or unlock the handle shaft 122, the handle shaft 122 can slide along the lock disk 110, and the handle body 121 can extend relative to the lock disk 110.

[0046] Furthermore, the handle shaft 122 may be provided with a receiving groove 1221 along its axial direction, and the elastic member 130 is provided along the receiving groove 1221 and abuts against the bottom wall of the receiving groove 1221 and the lock plate 110 .

[0047] Optionally, the shape of the receiving groove 1221 is substantially similar to that of the elastic member 130 so as to accommodate the elastic member 130 .

[0048] Optionally, the elastic member 130 is a spring.

[0049] In an optional embodiment, the lock disk 110 includes a base 113 and a sleeve 114 connected to each other, the locking assembly 140 is disposed on the base 113 , the handle shaft 122 is sleeved in the sleeve 114 and can slide along the sleeve 114 , and the elastic member 130 is supported between the handle shaft 122 and the sleeve 114 .

[0050] It should be understood that the sleeve 114 and the base 113 are connected to each other and are substantially T-shaped. The T-shape is substantially similar to the T-shape of the handle member 120 , so that the handle shaft 122 can slide in the sleeve 114 .

[0051] Optionally, the sleeve 114 may be provided with a closed bottom structure 1141, and the bottom end is used to abut against the elastic member 130. As shown in the figure, the elastic member 130 is sleeved on and abuts against the bottom structure 1141.

[0052] Optionally, a groove structure or a hole structure 1131 matching the shape of the handle body 121 is provided on the base 113. When not in use, the handle body 121 is stored in the groove structure or the hole structure 1131, so that the T-shaped handle is easy to store and place.

[0053] Please refer to Figure 4In an optional embodiment, a first limiting structure 1142 is provided on the sleeve 114, and a second limiting structure 1223 is provided on the handle shaft 122. The second limiting structure 1223 can slide relative to the first limiting structure 1142. The first limiting structure 1142 and the second limiting structure 1223 are used together to limit the sliding stroke of the handle shaft 122 relative to the sleeve 114.

[0054] It can be understood that the first limiting structure 1142 and the second limiting structure 1223 cooperate with each other to limit the sliding stroke of the handle shaft 122, that is, the handle shaft 122 can only slide within a certain stroke, that is, the length of the handle body 121 extending out of the lock disk 110 is jointly limited by the first limiting structure 1142 and the second limiting structure 1223.

[0055] Optionally, the first limiting structure 1142 and the second limiting structure 1223 are structures in which a groove and a protrusion cooperate with each other. For example, the first limiting structure 1142 is a protrusion, which can be a limiting bolt or the like; the second limiting structure 1223 is a slide groove, the width of which is slightly larger than the width of the protrusion, so as to facilitate smooth sliding.

[0056] In an optional embodiment, the T-shaped handle may further include a felt 150 , which is disposed in the sleeve 114 , and the handle shaft 122 may slide relative to the felt 150 .

[0057] Optionally, a concave groove is provided on the sleeve, and the felt 150 is installed in the concave groove. When the handle shaft 122 moves, the felt 150 can remove foreign matter such as sand and dust on the surface of the handle shaft 122 to prevent it from entering the sleeve and causing the handle to be stuck.

[0058] Please refer to Figure 6 In an optional embodiment, the T-shaped handle structure 100 may further include a limit rod 160 , and both ends of the limit rod 160 are rotatably connected to the lock plate 110 and the handle member 120 .

[0059] It should be noted that the limiting pull rod 160 is used to limit the handle shaft 122 , and the limiting method may be to limit the rotation angle of the handle shaft 122 , or to limit the rotation angle and the rotation direction of the handle shaft 122 at the same time.

[0060] Please refer to Figures 1 to 6, the beneficial effects of the embodiment of the present invention include, for example: the locking assembly 140 is used to lock or unlock the handle 120, the handle 120 and the lock disk 110 can move relative to each other, and when the locking assembly 140 unlocks the handle 120, the handle 120 can move relative to the lock disk 110. At this time, the elastic member 130 stretches, and the elastic force acts on the handle 120 to make it extend relative to the lock disk 110. When the T-shaped handle described in the embodiment of the present invention is in use: the handle 120 is unlocked by the locking assembly 140 set on the lock disk 110, and the handle 120 can move relative to the lock disk 110 and extend relative to the lock disk 110 under the action of the elastic member 130. The extended handle can realize the operation under the current working condition. In the above-mentioned use process, there is no limitation on the position of the operator, and the operator can be located on either side of the lock disk 110. That is to say, the operator can operate on both sides of the lock disk 110, and the operation is convenient, which is suitable for narrow areas and spaces where it is inconvenient for people to move.

[0061] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
