All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.
[0028] like Figure 1 As shown, this utility model provides a concealed handle, including a mounting base, which includes a first mounting surface 1 and a second mounting surface 2 disposed opposite to each other. The first mounting surface 1 extends partially toward the second mounting surface 2 and forms a recess 11. The concealed handle also includes a handle assembly 4 for sliding locking, and the recess 11 and the second mounting surface 2 are connected as one unit by the handle assembly 4.
[0029] Furthermore, this application does not specifically limit the material and shape of the mounting base, the material of which includes, but is not limited to, stainless steel, alloy, rigid plastic and copper; the shape of which includes, but is not limited to, rectangle, square, ellipse and circle. Moreover, the outer edges of the first mounting surface 1 and the second mounting surface 2 of this application are smooth and have no sharp parts, making the mounting base safer overall and eliminating safety hazards such as scratches.
[0030] Furthermore, this application mounts the mounting base onto a corresponding base via the second mounting surface 2. This base includes, but is not limited to, furniture or office supplies such as cabinets, doors, and drawers. Moreover, for ease of installation, the second mounting surface 2 has mounting holes through which bolts or other connectors are used to securely embed the mounting base into the base.
[0031] Furthermore, the first mounting surface 1 and the recessed portion 11 are integrally formed in this application, and the dimensions of the recessed portion 11 are designed according to the actual needs of the handle assembly 4, aesthetics, and ease of operation.
[0032] Furthermore, the handle assembly 4 of this application is embedded in the mounting base through the recess 11, so that the handle as a whole has no exposed protrusions, making it more aesthetically pleasing and safer. Moreover, this application achieves the connection locking and unlocking between the concealed handle and the base through the sliding of the handle assembly 4, which has the advantages of simple operation and convenient use.
[0033] Furthermore, such as Figure 3 As shown, the handle assembly 4 includes a slide groove 41, which is installed on the side of the second mounting surface 2 opposite to the first mounting surface 1 and forms a slidable space between it and the second mounting surface 2. A gap is provided on the second mounting surface 2, and the slide groove 41 partially extends through the gap into the recess 11 to form a support platform 411. Furthermore, the installation position of the slide groove 41 on the second mounting surface 2 is designed according to actual needs, such as being installed in the middle of the second mounting surface 2 laterally or longitudinally. Installation methods include, but are not limited to, welding and bolting connections. Specifically, the slidable space of the slide groove 41 is designed according to actual needs, and to ensure smooth sliding, the interior of the slide groove 41 is smooth.
[0034] Furthermore, the handle assembly 4 also includes a slider 42, which can extend into the slide groove 41 and slide along the support platform 411. The slider 42 is sized to match the slide groove 41 to ensure that the slider 42 can slide smoothly in the slide groove 41 without shifting or loosening.
[0035] Furthermore, the sliding member 42 includes a first sliding plate 421 and a second sliding plate 422. The sliding member 42 extends into the slide groove 41 through the first sliding plate 421 and drives the first sliding plate 421 to slide through the second sliding plate 422. The second sliding plate 422 can slide along the support platform 411, and both the second sliding plate 422 and the support platform 411 are provided with locking holes 423 for placing locking members to connect the second sliding plate 422 and the support platform 411 together. In this application, the slide groove 41 and the sliding member 42 can be formed by cold-rolled steel stamping, which has higher strength than die-cast parts such as zinc alloy, is less prone to damage, and has a longer service life. Furthermore, the first sliding plate 421 and the second sliding plate 422 can be integrally formed, or they can be connected together by welding or other fixing methods. Furthermore, the second sliding plate 422 can extend into the recess 11 through the gap in the second mounting surface 2, and the second sliding plate 422 can be slidably placed on the plane of the support platform 411. It can contact the support platform 411 or have a gap between it and the support platform 411, as long as it can slide back and forth along the support platform 411. Specifically, as Figure 2 As shown, the locking element in this application can be a commonly used brass lock or plastic lock.
[0036] Furthermore, the recess 11 of the first mounting surface 1 of this application can be an open structure, which is surrounded on all four sides and has no bottom surface, so that the support platform 411 and the second sliding plate 422 can directly extend into the recess 11; or, the recess 11 is surrounded on all four sides and has a bottom surface, and a gap is provided on the bottom surface for the support platform 411 and the second sliding plate 422 to extend into.
[0037] Furthermore, there are at least two keyholes 423 to provide more placement positions for the locking element.
[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the width of the support platform 411 is less than or equal to the depth of the recess 11, and the length of the second sliding plate 422 extending into the recess 11 is less than or equal to the width of the support platform 411. Through the above-mentioned dimensional design, this application meets the requirement that both the handle assembly 4 and the lock can be built into the mounting base, and the overall non-protruding structure is more aesthetically pleasing.
[0039] Furthermore, a baffle 424 is provided on the second sliding plate 422. In this application, the baffle 424 serves to limit and facilitate sliding. When it is necessary to slide the second sliding plate 422, the user's finger can be restricted in the second sliding plate 422 by the baffle 424, making it easier to apply force by using the baffle 424 to push the second sliding plate 422 to slide.
[0040] like Figure 2As shown, this utility model also provides a lock, including the aforementioned concealed handle and a locking plate 3 for cooperating with the handle assembly 3. Further, the locking plate 3 can be installed in the mounting groove of the base, and the handle assembly and the locking plate are connected by sliding the handle assembly, thereby completing the locking process; alternatively, the locking plate 3 is installed on the handle assembly, and a locking tongue fixing buckle is installed on the base to cooperate with the locking plate, and the locking plate and the locking tongue fixing buckle are connected by sliding the handle assembly, thereby completing the locking process.
[0041] Furthermore, such as Figure 4 As shown, if the user does not need a padlock, the sliding groove and handle assembly of the concealed handle can be removed, or the second mounting surface can be directly replaced, so that it becomes a single handle only through the recess of the first mounting surface 1.
[0042] Furthermore, such as Figure 1 and Figure 4 As shown, when the concealed handle of this application is installed on the base of cabinet doors or drawer doors made of various materials such as wood, metal, and plastic, its usage method is as follows:
[0043] The user places their finger on the second sliding plate 422 and applies force to slide the second sliding plate 422 to the locked position. At this time, the handle assembly 4 is connected to the locking plate 3 on the base. The padlock locks the position of the second sliding plate 422 through the second sliding plate 422 and the lock hole 423 on the support platform 411, thus locking the handle.
[0044] When unlocking is required, remove the padlock and slide the second sliding plate 422 to the unlock position. At this time, the handle assembly 4 separates from the lock plate 3 on the base, and the user can open the cabinet door or drawer door.
[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
