Description

Technical Field

[0001] The utility model relates to the technical field of door lock handles, in particular to a door lock handle structure which can be switched freely. Background Art

[0002] Door handles are indispensable door accessories. They are both decorative and functional. Door handles are divided into materials such as ceramic, solid wood, metal, glass, crystal, plastic, alloy, etc. Door handles are divided into single-hole spherical, single-hole bar, Japanese style, modern Chinese style, European style, etc. according to their shapes. People can choose the material according to their own needs.

[0003] The current push-pull lock has two types of handle structures: fixed or movable. For the fixed handle, it is necessary to open the keyhole of the lock core on the front of the handle, which affects the appearance. The movable structure will become loose over time, affecting the user experience of the product. In order to solve the above problems, we propose a door lock handle structure that can be freely switched. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems thereof is: a freely switchable door lock handle structure, comprising a door lock panel; a door lock handle, the bottom of the door lock handle is slidably connected to the outer side of the door lock panel; a fixed cover plate, the bottom of the fixed cover plate is fixedly connected to the bottom of the inner cavity of the door lock panel; a spring, the bottom end of the spring is fixedly connected to the top of the fixed cover plate; a locking mechanism, the top of the locking mechanism is slidably connected to the bottom of the door lock handle, the locking mechanism is used to fix the door lock handle, when in use, the locking mechanism and the door lock handle cooperate with each other, so that the door lock handle is fixed and cannot be rotated under normal circumstances, and under special circumstances, the locking mechanism releases the door lock handle so that the door lock handle can rotate freely, which well solves the appearance impact and user experience impact caused by the handle structure.

[0005] Preferably, the inner side of the door lock panel is rotatably connected to a rotating mechanism, the outer side of the rotating mechanism is fixedly connected to the inner side of the door lock handle, the outer side of the door lock panel is slidably connected to a lock core cover, and the lock core cover is located directly in front of the lock core. By providing the lock core cover to cover the lock core, the lock core is prevented from affecting the appearance of the handle, thereby reducing the influence of the lock core on the appearance.

[0006] Preferably, the spring is located between the locking mechanism and the fixed cover plate, the top of the spring is fixedly connected to the bottom of the locking mechanism, the outer side of the locking mechanism is slidably connected to the inner side of the door lock panel, the outer side of the locking mechanism passes through the door lock panel and extends to the outside of the door lock panel, and the state of the door lock handle is affected by the state of the locking mechanism, so that the door lock handle is usually in a fixed state and will not be frequently rotated to cause the handle to loosen.

[0007] The beneficial effects of the utility model are as follows:

[0008] 1. The utility model provides a locking mechanism so that the door lock handle is fixed and cannot be rotated under normal circumstances. Only when necessary, the locking mechanism is pushed to release the door lock handle so that the door lock handle can be rotated, thereby avoiding the handle from becoming loose due to frequent rotation, which affects the user experience of the product.

[0009] 2. The utility model sets the lock core on the door lock panel by arranging a lock core cover. Only when it is needed, the door lock handle is turned to expose the lock core, avoiding opening the lock core key hole on the front of the handle to affect the appearance.

[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0014] Embodiment 1:

[0015] See also Figure 1-Figure 2The utility model provides a technical solution: a freely switchable door lock handle structure, including a door lock panel 7; a door lock handle 1, the bottom of the door lock handle 1 is slidably connected to the outer side of the door lock panel 7; a fixed cover plate 5, the bottom of the fixed cover plate 5 is fixedly connected to the bottom of the inner cavity of the door lock panel 7; a spring 4, the bottom end of the spring 4 is fixedly connected to the top of the fixed cover plate 5; a locking mechanism 3, the top of the locking mechanism 3 is slidably connected to the bottom of the door lock handle 1, and the locking mechanism 3 is used to fix the door lock handle 1. On the basis of the existing design scheme, this mechanism adds an opening at the bottom of the door lock panel 7, and at the same time adds a locking mechanism 3, a spring 4, and a fixed cover plate 5. Under normal circumstances, the locking mechanism 3 acts on the door lock handle 1, resulting in the door lock handle 1 being unable to rotate. When the door lock handle 1 needs to be rotated, the locking mechanism 3 is pushed downward. At this time, the door lock handle 1 can normally rotate 45° left and right.

[0016] Working principle:

[0017] When in use, this mechanism is fixedly installed on the door. Based on the existing design scheme, this mechanism adds an opening at the bottom of the door lock panel 7, and adds a locking mechanism 3, a spring 4 and a fixed cover plate 5. Under normal circumstances, the fixed cover plate 5 fixes the spring 4 so that the spring 4 is fixed in the groove of the locking mechanism 3, and the locking mechanism 3 extends out of the surface of the door lock panel 7. The spring 4 drives the locking mechanism 3 to extend into the groove at the bottom of the door lock handle 1. The locking mechanism 3 acts on the door lock handle 1, causing the handle to be unable to rotate. When opening the door, the door lock is controlled to open through the door lock panel 7, and then the door is opened by pulling or pushing the door lock handle 1.

[0018] Embodiment 2:

[0019] like Figure 1-Figure 2 As shown, the inner side of the door lock panel 7 is rotatably connected to a rotating mechanism 2, the outer side of the rotating mechanism 2 is fixedly connected to the inner side of the door lock handle 1, the outer side of the door lock panel 7 is slidably connected to a lock core cover 6, and the lock core cover 6 is located directly in front of the lock core. The locking mechanism 3 and the door lock handle 1 cooperate to make the door lock handle 1 fixed under normal circumstances. When it is necessary to use a key to open the door or emergency power supply, the door lock handle 1 can be rotated. At this time, the lock core cover 6 is opened, and the user can open the door with a key or emergency power supply. The lock core cover 6 is provided to cover the lock core, so as to avoid the lock core affecting the appearance of the handle, thereby reducing the influence of the lock core on the appearance.

[0020] The spring 4 is located between the locking mechanism 3 and the fixed cover plate 5. The top of the spring 4 is fixedly connected to the bottom of the locking mechanism 3. The outer side of the locking mechanism 3 is slidably connected to the inner side of the door lock panel 7. The outer side of the locking mechanism 3 passes through the door lock panel 7 and extends to the outer side of the door lock panel 7. The locking mechanism 3 is driven by the spring 4 to fix the door lock handle 1. The top of the spring 4 extends into the groove at the bottom of the locking mechanism 3 to prevent the locking mechanism 3 from deviating. The state of the locking mechanism 3 affects the state of the door lock handle 1, so that the door lock handle 1 is usually in a fixed state and will not be frequently rotated to cause the handle to loosen.

[0021] Working principle:

[0022] When in use, if there is a problem such as a failure of the door lock panel 7 or a power outage, and it is necessary to use a key to open the door or emergency power supply, the locking mechanism 3 is pushed downward, and the locking mechanism 3 drives the spring 4 to compress. When the top of the locking mechanism 3 moves to a position lower than the door lock panel 7, the locking mechanism 3 is no longer in contact with the door lock handle 1. At this time, the door lock handle 1 can be rotated left and right normally. The door lock handle 1 is rotated, and the door lock handle 1 drives the rotating mechanism 2 to rotate, and then the lock core cover 6 is opened. At this time, the door can be opened by the key;

[0023] After opening the door, if you need to restore the door lock handle 1 to the vertical state, you can directly turn the door lock handle 1 to the left or right to turn the door lock handle 1 to the vertical state. At this time, press the locking mechanism 3 upwards. Under the influence of its own elastic force, the spring 4 drives the locking mechanism 3 to be inserted into the groove of the door lock handle 1. The locking mechanism 3 fixes the door lock handle 1, and the door lock handle 1 returns to the vertical state. At this time, the door lock handle 1 is in a fixed state and will not rotate.

[0024] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
