Description

Technical Field

[0001] The utility model belongs to the field of door opening and closing, and particularly relates to a door with a hidden handle. Background Art

[0002] For current doors, a handle needs to be installed for opening and closing. For convenience, most of them are installed with a "C"-shaped handle.

[0003] However, this kind of handle needs to be installed separately during the processing and requires many components. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a door with a hidden handle to solve the problem of the current cumbersome handle installation.

[0005] To solve the above problems, the utility model adopts the following technical solutions:

[0006] A door with a hidden handle, including a rectangular door frame. A core board is arranged on the rear side of the door frame. The door frame includes four frame bars distributed in a rectangle. At least one of the inner sides of the frame bars is provided with a handle groove.

[0007] Furthermore, the four frame bars include two horizontal frame bars and two vertical frame bars. The two horizontal frame bars are located between the two vertical frame bars. Connection slopes and locking protrusions arranged on the connection slopes are provided at both ends of the two horizontal frame bars. Fitting slopes are provided on the sides of the two vertical frame bars close to the two horizontal frame bars. The fitting slopes are adapted to the connection slopes, and locking grooves corresponding to the locking protrusions are arranged on the fitting slopes.

[0008] Furthermore, the fitting slopes are arranged along the length direction of the vertical frame bars, and the fitting slopes between the two horizontal frame bars form the handle groove.

[0009] Furthermore, the locking grooves penetrate through the vertical frame bars. The left and right side edges of the core board are adapted to the fitting slopes and are inserted into the locking grooves. Screws for fixing the core board on the vertical frame bars are arranged at the four corners of the core board.

[0010] Furthermore, placing grooves are provided on the rear sides of the two horizontal frame bars, and the upper and lower sides of the core board are arranged in the placing grooves.

[0011] Furthermore, an anti-scratch surface is arranged between the front side edges of the fitting slopes and the front side edges of the vertical frame bars.

[0012] Furthermore, veneers adapted to the anti-scratch surfaces are arranged at both ends of the horizontal frame bars.

[0013] The remarkable beneficial effects obtained by the utility model:

[0014] 1. The present application processes two handle grooves on the two vertical frames on the door and designs the frame strips at other positions on the door, so that the handles do not need to be installed separately. A door with handles can be formed during the door frame processing and production process. The overall design is simple, beautiful and generous, which effectively solves the problem that the current door handles need to be installed separately and the installation is cumbersome.

[0015] 2. The shape design of the core board can effectively improve the bonding force between the core board, vertical frame bars and horizontal frame bars, and increase the overall firmness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] It should be noted that the inner side mentioned in the present application refers to the opposite side between the frame bars.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a door with a hidden handle comprises a rectangular door frame, a core board 9 is installed on the rear side of the door frame, and the door frame comprises four rectangularly distributed frame strips, and a handle groove 1 is opened on the inner side of at least one of the frame strips;

[0025] Specifically, the four frame bars include two horizontal frame bars 2 and two vertical frame bars 3. The two horizontal frame bars 2 are located between the two vertical frame bars 3. Both ends of the two horizontal frame bars 2 are processed with connecting bevels 5 and locking protrusions 4 located on the connecting bevels 5. The sides of the two vertical frame bars 3 close to the two horizontal frame bars 2 are processed with fitting bevels 6. The fitting bevels 6 are adapted to the connecting bevels 5. The fitting bevels 6 are provided with locking grooves 7 adapted to the locking protrusions 4. The two ends of the two horizontal frame bars 2 are respectively inserted into the locking grooves 7 on the two vertical frame bars 3 to form a rectangular door frame; easy to install

[0026] In this embodiment, the fitting slope 6 is arranged along the length direction of the vertical frame bar 3, and the fitting slope 6 between the two horizontal frame bars 2 forms a handle groove 1;

[0027] The locking groove 7 passes through the vertical frame bar 3 along the length direction of the vertical frame bar 3, the left and right sides of the core board 9 are adapted to the fitting inclined surface 6 and inserted into the locking groove 7, and screws 8 for fixing the core board 9 to the vertical frame bar 3 are installed at the four corners of the core board 9; the arrangement of the core board 9 and the screws 8 can relatively fix the two vertical frame bars 3 together, and at the same time can fix the two horizontal frame bars 2 between the two vertical frame bars 3.

[0028] In combination with the above, the present application processes two handle grooves 1 on the two vertical frames on the door and designs the frame strips at other positions on the door, so that the handles do not need to be installed separately. A door with handles can be formed during the door frame processing and production process. The overall design is simple, beautiful and generous, which effectively solves the problem that the current door handles need to be installed separately and the installation is cumbersome.

[0029] It should be noted that when the door is opened by rotating, a handle groove 1 is processed on the vertical frame bar 3 away from the rotating side; when the door is a sliding door, the handle grooves 1 can be processed on both vertical frame bars 3 on the door.

[0030] Example 2

[0031] like Figure 1-4 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, in order to avoid scratches on human hands caused by the opening of the handle groove 1, an anti-scratch surface 10 of the vertical core board 9 is left between the front side edge of the fitting slope 6 and the front side edge of the vertical frame bar 3. The side edge of the anti-scratch surface 10 has an arc transition. The setting of the anti-scratch surface 10 can avoid scratches on the one hand, and on the other hand, it can also increase the aesthetics of the opening of the handle groove 1.

[0032] The transverse frame strip 2 is processed with a veneer 11 that matches the anti-scratch surface 10 .

[0033] It should be noted that the protective surface may also be an arc surface.

[0034] Example 3

[0035] like Figure 4 As shown, the structure of this embodiment is substantially the same as that of the embodiment 1. The difference between this embodiment and the embodiment 1 is that in this embodiment, the rear sides of the two horizontal frame bars 2 are processed with placement grooves, and the upper and lower sides of the core plate 9 are provided with stepped grooves adapted to the placement grooves;

[0036] By setting the placement groove, when the core board 9 is fixed to the vertical frame bar 3, the core board 9 can abut and fix the horizontal frame bar 2, thereby further improving the bonding force between the horizontal frame bar 2 and the vertical frame bar 3.
