Door lock with push-pull handle

Abstract

The invention discloses a door lock equipped with a pull-push handle. According to the invention, the handle door lock herein can open a door when a latch bolt of the door lock is pulled in not by rotating a handle of the door lock left and right but by rotating the handle back and forth. According to the invention, a cover part which has a rubber is used in a manner such that the rubber deforms when the handle is rotated back and forth so as to maintain the adhering state between the rubber and a main body, which can also prevent foreign matters from entering the joining part of the handle of the door lock, wherein the rubber is joined in a manner that the rubber encloses and adheres tightly to the main body of the handle. The handle is made of an elastic and flexible material. The handle is joined to an installation part of the housing of the door lock in a back and forth rotation manner.

Description

technical field [0001] The invention relates to a door lock with push-pull handle. The invention does not need to rotate the handle of the door lock left and right, but pulls or pushes the handle of the door lock back and forth to make the handle turn, so as to introduce the latchbolt of the door lock, so that the door lock can be opened. For the door, the present invention adopts a cover member with a rubber part, and deforms the rubber part when the handle is turned back and forth, so as to keep the rubber part in a tight state with the main body, thereby preventing foreign matter from flowing into the handle joint of the door lock. The inside of the part, wherein the rubber part is combined in a way that surrounds and clings to the main part of the handle. It is formed of a flexible material with elasticity. way combined. Background technique [0002] Usually, such as figure 1 , Figure 7 to Figure 9 As shown, the digital door lock (Door Lock) is composed of the follow...

Problems solved by technology

[0005] This kind of door lock with a rotating handle has the problem of being inconvenient to open the door when the hands are full of goods or in other situations where it is difficult to perform rotating operations

[0006] In particular, existing digital door locks have the following problem: the door can only be opened by pulling or pushing when the rotary handle is rotated more than a predetermined angle, so the frail elderly, disabled or children It is inconvenient to open the door for users who have difficulty maintaining the rotary operation of the handle

[0009] However, if Figure 10 As shown, since the authorized patent is a structure in which the handle joint part of the door lock (that is, the part that is hinged with the handle 110, 210) is exposed to the outside, therefore, when foreign matter flows into the handle joint part and is clamped, resulting in The push and pull action of the handle is not smooth, or in severe cases, the handle does not return to its original shape after the door is opened, making locking impossible

[0010] That is, in order to use the push-pull type handle safely and conveniently, it is necessary to block the phenomenon that the foreign matter flows into the handle junction from the root, but, for the push-pull type door lock, after pushing or pulling the handle 110,210 to make the handle When 110 and 210 are rotated, because the position (height) of the main body of the handle changes, it is impossible to combine parts such as the cover that can completely seal the joint of the handle. Even if an independent cover structure that can correspond to it is provided, it can only The working structure of the cover is complicated, and even if such a structure is present, if a foreign object is caught between the working structures of the cover, as a result, there is a risk that the above-mentioned problems will repeatedly occur.
