Description

Technical Field

[0001] The utility model belongs to the technical field of furniture, and in particular relates to a cabinet body with a small-rounded hidden mortise and tenon joint structure. Background Art

[0002] In the traditional cabinet design concept, the treatment of corners has always been a key consideration. In order to ensure safety during use and avoid injuries caused by sharp corners, the industry generally adopts rounded corners. Figure 1 As shown in the figure, the traditional method of making rounded corners of a cabinet is to splice a horizontal board and a vertical board with a rounded corner splicing strip through a simple snap-fit ​​structure. Although this splicing method achieves the rounded corner effect, the rounded corner splicing on the horizontal board and the vertical board is extremely easy to crack, and the splicing marks on the horizontal board and the vertical board are obvious, which is not conducive to maintaining the overall beauty of the cabinet.

[0003] On the other hand, the traditional cabinet support structure is mainly based on four legs. This design is relatively fragile when facing external force collision, which easily causes the risk of the cabinet to topple over. More importantly, the four-legged support structure exerts a large pressure on the ground when bearing weight. Over time, it is easy to cause wear and even damage to the ground material. Taking the Chinese patent with publication number CN203506012U as an example, the shoe cabinet design of this prior art adopts this four-legged support structure. Although it meets the basic support requirements, it still needs to be improved in terms of stability and ground protection.

[0004] Therefore, there is an urgent need for a cabinet with a small-rounded hidden mortise and tenon connection structure to achieve hidden processing of the small rounded corners and optimize the supporting structure of the cabinet. Summary of the invention

[0005] In view of the problems in the related technology, the utility model proposes a cabinet with a small-rounded corner hidden mortise and tenon connection structure to overcome the above-mentioned technical problems existing in the existing related technology. The horizontal plate and the rounded corner structure described in the utility model are arranged as one piece, avoiding the problems of easy cracking and obvious splicing marks caused by the traditional cabinet rounded corner production method; the supporting structure adopted at the bottom of the cabinet body is a supporting frame, and the frame bars are connected in pairs. Compared with the four-legged supporting structure of the prior art, the supporting frame of the utility model significantly expands the contact area with the ground, thereby dispersing the force to avoid wearing the ground.

[0006] The technical solution of the utility model is implemented as follows: a cabinet with a small-rounded hidden mortise and tenon joint structure comprises a cabinet body, wherein the cabinet body comprises an inner frame and an outer frame wrapped around the inner frame;

[0007] The outer frame includes upper and lower horizontal panels and left and right side panels; each of the horizontal panels is a solid wood structure without splicing; wherein both ends of each of the horizontal panels are provided with a rounded corner structure, and each of the rounded corner structures is connected to the corresponding side panels through a hidden mortise and tenon structure; in the utility model, the horizontal panel and the rounded corner structure are integrally arranged, avoiding the problems of easy cracking and obvious splicing marks caused by the traditional cabinet rounded corner production method;

[0008] The side plate includes upper and lower joint surfaces; the hidden mortise and tenon structure includes a plurality of tenons extending outward from the joint surface, and a plurality of tenon grooves arranged on the horizontal plate; the tenon grooves are recessed from the inner side of the horizontal plate toward the outer side of the horizontal plate; the tenons are engaged and connected with the corresponding tenon grooves;

[0009] It also includes a supporting frame arranged at the bottom of the outer frame, which is a rectangular frame structure, including a front frame bar, a rear frame bar, a left frame bar and a right frame bar which are spliced ​​end to end in sequence, and the front frame bar and the rear frame bar are also connected by a horizontal bar; the top of each frame bar is connected to the bottom of the outer frame, and the bottom of each frame bar is pressed against the ground together; in the utility model, the supporting structure adopted at the bottom of the cabinet body is a supporting frame, and the frame bars are connected in pairs and are not easy to tip over. Compared with the four-legged supporting structure in the prior art, the supporting frame of the utility model not only optimizes the contact mode with the ground, but also significantly expands the contact area with the ground, thereby dispersing the force and effectively avoiding unnecessary damage to the ground material.

[0010] Furthermore, the radius of the chamfered corner structure is greater than or equal to the thickness of the transverse plate, and the radius size range of the chamfered corner structure is 15mm to 30mm; the depth of the mortise and tenon groove is less than the thickness of the transverse plate; and the height of the tenon protrusion does not exceed the depth of the mortise and tenon groove.

[0011] Furthermore, the tenon is columnar, square, truncated cone or prism-shaped; the shapes of the tenon groove and the tenon are adapted to each other.

[0012] Furthermore, the width of the tenon protrusion is smaller than the thickness of the side panel, and the tenon is not connected to the edge of the joint surface. When the tenon is connected to the mortise, it is helpful to hide the joint marks, further avoiding the problem of obvious joint marks caused by the traditional cabinet rounding method.

[0013] The thickness of each of the transverse plates and each of the side plates ranges from 15 mm to 22 mm.

[0014] Furthermore, the edges of the support frame do not exceed the edges of the bottom of the outer frame.

[0015] Furthermore, the width L1 of the bottom of each frame bar is greater than the width L2 of the top of each frame bar. The design of the bottom of the frame bar being greater than the top can effectively avoid top-heaviness and prevent the main body of the cabinet from tipping over.

[0016] The length dimensions of the left frame bar and the right frame bar are smaller than the length dimensions of the front frame bar and the rear frame bar; the distance between the outer edges of the tops of the front frame bar and the rear frame bar corresponding to the front and rear side edges of the outer frame body is 1 / 3 of the width L1 of the bottom of the frame bar. Since the linear distance in the front and rear directions of the main body of the cabinet is short and the center of gravity is relatively high, the support span of the support frame in the front and rear directions is small, resulting in the main body of the cabinet being prone to tipping over in the front and rear directions. By reasonably setting the outer edges of the bottoms of the front frame bar and the rear frame bar, the stability of the support of the support frame can be ensured on the premise of avoiding hitting the feet.

[0017] The height of each frame bar is 45 mm.

[0018] Furthermore, an inwardly concave notch is provided on the outer side of each frame bar; the depth of the notch is less than the width L1 of the bottom of the frame bar; the shape of the notch includes a concave shape and a U shape. In the present utility model, this design of the inwardly concave notch can effectively avoid the direct collision between the user's toes and the outer side of the frame bar, thereby reducing the risk of accidental injury.

[0019] The value range of the width L1 of the bottom of the frame bar is 45 - 80 mm.

[0020] Furthermore, the inner frame includes a longitudinal partition plate longitudinally arranged in the middle of the main body of the cabinet and several transverse partition plates arranged transversely; the bottom of the longitudinal partition plate is connected to the cross bar.

[0021] Furthermore, the main body of the cabinet further includes several drawers installed on the inner frame; one side of the drawer is exposed outside the main body of the cabinet, and a handle is provided on the outer plate of this side of the drawer; the outer plate of the drawer is recessed inward to form the handle. This design is beneficial to reducing the use of traditional alloy or plastic handles. At the same time, the recessed handle also improves the convenience and safety of user use and reduces the possibility of accidental collision.

[0022] Furthermore, the outer frame body further includes a back plate for dust prevention. The edges of the back plate are respectively connected to the cross plate of the outer frame body and the side plate of the outer frame body, and the inner frame is wrapped therein.

[0023] The beneficial effects of the present utility model:

[0024] (1) The utility model provides a cabinet with a small rounded corner hidden mortise and tenon joint structure, comprising a cabinet body, wherein the cabinet body comprises an inner frame and an outer frame wrapped around the inner frame; the outer frame comprises upper and lower horizontal panels and left and right side panels; each of the horizontal panels is a whole solid wood structure without splicing, and has better pressure resistance and durability than spliced ​​horizontal panels; wherein both ends of each of the horizontal panels are provided with a rounded corner structure; the horizontal panel and the rounded corner structure described in the utility model are arranged as a whole, thereby avoiding the problem of easy cracking caused by the traditional cabinet rounded corner manufacturing method; moreover, since the rounded corner is part of the whole solid wood structure, its strength and stability are guaranteed, making the cabinet more durable;

[0025] (2) Each of the rounded corner structures is connected to the corresponding side panels through a hidden mortise and tenon structure, which helps to avoid the problem of obvious splicing marks caused by the traditional cabinet rounding method and enhance the overall aesthetics of the cabinet;

[0026] (3) It also includes a support frame arranged at the bottom of the outer frame, the support frame is a rectangular frame structure, including a front frame bar, a rear frame bar, a left frame bar and a right frame bar which are spliced ​​end to end in sequence, and the front frame bar and the rear frame bar are connected by a horizontal bar; the top of each frame bar is connected to the bottom of the outer frame, and the bottom of each frame bar is pressed against the ground together; compared with the traditional four-legged support structure, the support frame design of the utility model not only improves the load-bearing capacity of the cabinet, but also enhances its anti-seismic performance. In addition, the enlarged contact area also reduces the pressure of the cabinet body on the ground, and avoids unnecessary damage to the ground material by dispersing the force.

[0038] like Figure 2 and Figure 5 As shown, this embodiment provides a cabinet with a small-rounded hidden mortise and tenon joint structure, including a cabinet body, wherein the cabinet body includes an inner frame and an outer frame wrapped around the inner frame;

[0039] The outer frame includes upper and lower horizontal boards 1 and left and right side boards 2; each of the horizontal boards 1 is a whole solid wood structure without splicing; wherein, both ends of each of the horizontal boards 1 are provided with a rounded corner structure 11, and each of the rounded corner structures 11 is respectively connected to the corresponding side board 2 through a hidden mortise and tenon structure 3; in this embodiment, the horizontal board 1 and the rounded corner structure 11 are integrally arranged, avoiding the problem of easy cracking and obvious splicing marks caused by the traditional cabinet rounded corner production method;

[0040] Specifically, the side panel 2 includes upper and lower joint surfaces; the hidden mortise and tenon structure 3 includes a plurality of tenons 31 extending outward from the joint surfaces, and a plurality of tenons 32 arranged on the transverse panel 1; the tenons 32 are recessed from the inner side of the transverse panel 1 toward the outer side of the transverse panel 1; the tenons 31 are snap-fitted and connected with the corresponding tenons 32.

By reasonably setting the outer edges of the bottoms of the front frame bar 41 and the rear frame bar 42, the stability of the support of the support frame 4 can be ensured on the premise of avoiding hitting the feet;

[0049] The height of each of the frame bars is 45 mm.

[0052] As Figure 3-4 shown, the inner frame includes a longitudinal partition board 5 arranged in the middle of the cabinet body, and several transverse partition boards 6 arranged horizontally; the bottom of the longitudinal partition board 5 is connected to the cross bar 45.

[0053] As Figure 2 and Figure 6 shown, the cabinet body further includes several drawers 7 installed on the inner frame; one side of the drawer 7 is exposed outside the cabinet body, and a handle 71 is provided on the outer plate 72 of this side of the drawer 7; the outer plate 72 of the drawer 7 is recessed inward to form the handle 71.
