Description

Technical Field

[0001] The present application relates to the technical field of door locks, and in particular to a door handle that can be easily installed. Background Art

[0002] When the door is opened or closed, the conventional opening method is to rotate the handle of the door handle assembly, and the handle acts on the rack on the lock tongue to engage the lock tongue, so that the lock tongue is retracted and the door can be opened.

[0003] Existing door handle assemblies, especially door handles in the home field, generally have preset grooves on the door panels to install the lock part and the lock tongue part of the door handle assembly. After installation, an embedded part is fixed on the outside of the preset groove, and finally an external fixing part is used to tighten it. When the door is frequently opened and closed, external forces will frequently be generated between the external fixing part and the embedded part, causing the two to tend to separate from each other, which will cause the two to loosen and affect the normal and stable use of the door handle. Summary of the Invention

[0026] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0027] Example:

[0028] Reference Figures 1 to 5 This embodiment provides a door handle that can be easily installed, including a lock tongue installed perpendicular to the door panel, an embedded part fixed to the door panel, and a handle for opening and closing. Figure 5The principle of rotating the handle to activate the lock assembly, causing the lock tongue to retract and thus unlock the door, is common knowledge in the art and will not be elaborated on here. An external fixture is mounted on the outer side of the inner insert through threaded engagement. The external fixture is provided with a fastening assembly. The fastening assembly is adapted to be adjusted after the external fixture is threadedly assembled and to form a snap fit with the inner insert to prevent the external fixture from axially disengaging from the inner insert. The snap fit formed between the fastening assembly and the inner insert allows the external fixture to be locked to the inner insert through threaded engagement and also provides a snap fit of the fastening assembly, thereby ensuring a more stable assembly and a longer-lasting fixation. Assembly requires only the adjustment limit of the fastening assembly, making installation simple.

[0029] like Figure 1 The handle shown is a common household circular handle, but the L-shaped handle commonly used on security doors can also be an equivalent replacement. Accordingly, in this embodiment, both the external fixing member and the internal insert are cylindrical, but in practice, they form a square shape on the security door. When fastened with screws, similar snap-fit ​​components can also share some of the external force, thereby extending the service life.

[0030] The fastening assembly includes a fastening member rotatably mounted on the side wall of the external fixing member. The internal insert has a fastening groove at a position corresponding to the fastening member. In the initial state, the fastening member is rotated away from the fastening groove. After the external fixing member is threadedly assembled onto the internal insert, the fastening member is rotated to engage with the fastening groove. In this embodiment, the rotation of the fastening member reinforces the internal insert after the external fixing member is fixed. When the external fixing member is subjected to external force after assembly, the fastening member and the fastening groove cooperate to offset the external force that may cause the external fixing member to separate from the internal insert, thereby reducing the external force on the assembly thread between the external fixing member and the internal insert, thereby ensuring a more stable and long-term fixation between the external fixing member and the internal insert.

[0031] like Figure 3 The fastening member is formed with a retaining portion, and the fastening slot is formed with a retaining slot. The fastening member is adapted to rotate into the retaining slot, with a portion of the retaining portion simultaneously entering the retaining slot to form a retaining position. The retaining portion serves to provide a position limit after the external fixing member and the internal insert are installed. When the handle is pulled to open the door, the external fixing member and the internal insert often generate an external force separating them. In this case, the retaining portion's restraining action can reduce the interaction between the assembly threads of the external fixing member and the internal insert, preventing damage to the threads that could affect subsequent stable use.

[0032] like Figure 4As shown, the buckle slot is a rectangular slot with inward-facing limiting steps on opposite sides of the slot top. Protrusions extend from the corresponding sides of the top of the fastening member. The wall thickness of the protrusions is less than that of the entire fastening member. The protrusions deform before the fastening member enters the buckle slot and return to their original shape afterward, allowing the protrusions and limiting steps to form a locked position during assembly. The locking cooperation between the limiting steps and the protrusions ensures good stability after the fastening member is rotated and set, preventing it from disengaging. To remove the fastening member, a force that deforms the protrusions frees them from the limiting steps.

[0033] The fastening member is provided with rotating shafts on opposite sides, each mounted on opposite sides of the buckle slot. A folding connection is provided between the fastening member and the innermost side of the buckle slot. The folding connection is adapted to adaptively deform when the fastening member rotates. The folding connection is preferably made of a material with good elastic deformation capacity and can be flexible. It primarily provides a stable connection between the fastening member and the external fixing member, preventing the fastening member from being connected to the external fixing member solely via the rotating shaft, which would generate a large force on the rotating shaft during use and thus shorten its service life.

[0034] The latching portion is formed by stamping and deforming the center of the fastening member. Alternatively, the latching portion can be configured as a column and welded to the fastening member. Both methods can produce a suitable latching portion to form a latching fit with the latching slot of the buckle slot.

[0035] An inner insert, a turning handle and an outer fixing part are respectively provided on both sides of the door panel; a fixing bolt is provided between the inner inserts on both sides, and the inner inserts and the outer fixing parts on both sides are provided with corresponding fixing holes, and the fixing holes are coaxially arranged with the center hole of the fixing bolt; the fixing holes on both sides are tightened by screws respectively to make the outer fixing parts and the inner inserts on both sides move toward the inner panel and be fixed.

[0036] The same position of the inner insert and the outer fixing piece facing the door panel is formed with an arc-shaped fixing portion by bending, and the arc-shaped fixing portion is acted upon when the screws are tightened in the fixing holes. Figure 1 The cooperation of the arc-shaped fixing portion, the fixing bolt and the screw can provide simple and stable installation conditions for the installation of the embedded component.

[0037] To further ensure the stability of the insert after installation, the insert is cut and bent towards the door panel to form a clamping part, which fits tightly with the preset groove of the door panel. The preset groove is a pre-opened installation groove on the door panel for installing door handles and lock tongues, which is a common technical feature in this field. Figure 5 The clamping parts shown in the figure, the two clamping parts arranged above and below can also form an inwardly tightened configuration, thereby further increasing the stability of the embedded part and the preset groove of the door panel after installation.

[0038] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
