The first cover 60A is disposed between the first assembling portion 51A and the first sleeve 30A, and has a first screwing portion 61A screwed with the first screwing portion 33A.
The second cover 60B is disposed between the second assembling portion 51B and the second sleeve 30B, and has a second screwing portion 61B screwed with the second screwing portion 33B.
As shown in fig. 6, which is a schematic view of the present embodiment, in the present embodiment, when a user rotates the first connecting member 11 counterclockwise, but not limited thereto, the user can also rotate clockwise, the first driving portion 72A is driven by the first connecting member 11, the first driving portion 72A and the first connecting member 11 rotate in the same direction, and the first driving portion 72A is driven by the first driving portion 72A, so that the first movable portion 43A penetrating through the first limiting hole 322A can be driven by the first driving portion 72A and separate from the first limiting portion 323A, because a spring (not shown) of the horizontal lock device in the prior art is frequently used for a long time to cause a releasing displacement of an internal component, through the design of the present invention, two springs (the first spring 40A and the second spring 40B) are respectively disposed in the limiting grooves of the two sleeves (the first sleeve 30A and the second sleeve 30B), and the structural strength is enhanced, the integral durability of the lockset is improved, and the purpose of prolonging the service life of the lockset is further achieved. The user can also rotate the second connecting member 12 in a counterclockwise direction or a clockwise direction, which is not described in detail since the above-mentioned operation is performed.
The above is the description of the structure and combination status of each component of the combination structure of a lock set provided by the present invention.
The present invention has the following effects.
First, the service life is increased. The handle of the horizontal lockset device in the prior art can not present the state parallel to the floor due to the fatigue of the internal spring after being used for a period of time, so the invention improves the defects, and the method is to add two strong and powerful springs (the first spring 40A and the second spring 40B) in two sleeves (the first sleeve 30A and the second sleeve 30B) to achieve the purposes of strengthening the internal structure and further prolonging the service life and smoothing the function of the horizontal lockset device.
Secondly, locking in a pressing mode. Because the horizontal lockset device in the prior art is locked by a knob, a user cannot clearly judge whether to lock and position the lock in appearance, and the knob has a small diameter, takes time to operate and does not apply force well in operation. Therefore, the present invention improves the above-mentioned disadvantages, and the pressing member 20 can be pressed and disposed in the first connecting member 11, so that the user can clearly determine whether to lock or not in appearance, and the pressing manner is easier to operate than the manner of the prior art knob. In addition, the knob is often too close to the door frame when applying force, so that the back of the hand of a user is often rubbed against the door frame, and therefore, the problem that the back of the hand is contacted with or collided with the door frame can be avoided by pressing the knob when locking.
And thirdly, a horizontal handle. The handle of the horn lock device in the prior art is spherical, so that the horn lock device is quite troublesome and is not easy to apply force to the old or the injured people. The first horizontal handle 50A and the second horizontal handle 50B are horizontal to the ground, and can be opened by slightly pressing the first grip part 52A and the second grip part 52B, so that the labor-saving effect is achieved if the old or disabled with a post crutch at home chooses the most ideal choice.
In summary, the above-mentioned embodiments and drawings are only preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the present invention should be covered by the present invention.
