Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a keyboard with a handrail, including a keyboard body 1 and a handrail 2 connected to the keyboard body 1, wherein the handrail 2 is connected to the keyboard body 1 through at least one self-locking connecting component 3. Realize by self-locking coupling assembling 3 with handrail 2 self-locking to keyboard body 1, combine both together, when operating keyboard body 1, support the wrist by handrail 2, make the operation more convenient comfortable.

Meanwhile, the upper end surface of the armrest 2 is provided with a slope 21, so that the wrist can be comfortable when the keyboard body 1 is operated.

In this embodiment, the self-locking connection component 3 includes a lock rod 31 disposed on the end surface of the armrest 2, and a self-locking switch 32 disposed on the keyboard body 1 and matched with the lock rod 31. The lock lever 31 is locked by the self-locking switch 32, so that the armrest 2 can be locked to the keyboard body 1.

Specifically, as shown in fig. 3 and 4, the end of the lock lever 31 has a push-lock portion 311, and a lock protrusion 3111 is respectively protruded on both sides of the push-lock portion 311, and specifically, a guide inclined surface 3112 is provided on an end surface of the lock protrusion 3111 to guide the push-lock portion 311 to push into between two elastic hooks 3221.

As shown in fig. 5 and 6, in the present embodiment, a bayonet 11 for the self-locking switch 32 to be inserted into is disposed on an end surface of the keyboard body 1 close to the armrest 2, and a hook 12 is disposed in the keyboard body 1 and located at two sides of the bayonet 11.

Specifically, as shown in fig. 7, the self-locking switch 32 includes a base 321 clamped on the hook 12, and a lock core 322 disposed in the bayonet 11 and movably connected to the base 321. Specifically, a boss 3211 is convexly provided at an end of the base 321, a limit protrusion 3212 is convexly provided at two sides of the base 321, and a clip 3213 for the hook 12 to clip into is formed between the boss 3211 and the limit protrusion 3212. Thus, when base 321 is positioned on bayonet 11 of keyboard body 1 and lock lever 31 is inserted into bayonet 11 and a force is applied to lock core 322, base 321 does not move.

Specifically, the end of the lock cylinder 322 has two elastic hooks 3221 which are oppositely arranged and used for hooking the lock rod 31, when the lock rod 31 applies acting force to the lock cylinder 322, the lock cylinder 322 is pushed into the base 321, and since the two elastic hooks 3221 have elasticity, an opening formed between the two elastic hooks 3221 becomes smaller, so as to hook the locking protrusion 3111 on the lock rod 31, thereby locking the lock rod 31; when the two elastic hooks 3221 are ejected out of the base 321, the opening formed between the two elastic hooks 3221 becomes larger, and then the locking protrusion 3111 on the lock lever 31 is disengaged, so that the lock on the lock lever 31 is released.

The self-locking switch 32 in this embodiment can be a common door lock switch on the market, and its specific internal structure and working principle are the same as those of the common door lock switch on the market. Specifically, reference may be made to the following patent documents: application No.: 201621425482.6, 200720181656.3.

When the armrest 2 is mounted on the keyboard body 1, the lock rod 31 is pushed into the bayonet 11 of the keyboard body 1, the push locking portion 311 of the lock rod 31 pushes the lock cylinder 322, as shown in fig. 8, so that the lock cylinder 322 moves into the base 321 and is locked in the base 321, at this time, the openings of the two elastic hooks 3221 on the lock cylinder 322 are reduced, the two elastic hooks 3221 hook the locking protrusion 3111 on the lock rod 31, so that the lock rod 31 is locked on the lock cylinder 322, as shown in fig. 9, thereby locking the armrest 2 on the keyboard body 1, and realizing the combination of the two.

Known from the concrete structure and the theory of operation of the conventional door lock switch in this field, after the self-locking switch 32 locks the locking rod 31, promote the locking rod 31 once more, can unlock the locking rod 31 from the self-locking switch 32, from this, realize the dismantlement separation of handrail 2 and keyboard body 1, then the user can select to use handrail 2, also can select not to use handrail 2, the possibility of giving the user more choices satisfies different users' different demands, improves the practicality. Meanwhile, in order to reduce the overall size and bring convenience to carrying, the armrest 2 can be detached from the keyboard body 1 to be carried, and the carrying is convenient, so that more convenience is brought to users.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
