Description

Technical Field

[0001] The present invention relates to the field of hardware handles, and in particular to a concealed handle structure for a door body and a cabinet body. Background Art

[0002] There are many cabinet devices in the home appliance industry, such as disinfection cabinets, wine cabinets, refrigerators, and constant temperature drying cabinets. Such cabinets include a cabinet body and a cabinet door. In order to ensure that the cabinet door tightly seals the opening of the cabinet body, a magnetic attraction structure is provided between the cabinet door and the opening of the cabinet body to realize the adsorption and sealing of the cabinet door to the opening of the cabinet body. However, as the service life increases, the magnetic force of the magnetic attraction structure will decrease, resulting in a decrease in the effect of the cabinet door sealing the cabinet body. In order to overcome the above problems, there appears a cabinet body provided with a lock structure between the cabinet door and the opening of the cabinet body. A fastening member is provided on the opening of the cabinet body, and a locking member for locking the fastening member is provided on the cabinet door. Before the user opens the cabinet door, a key is required to rotate the locking member to unlock it. After unlocking the fastening connection between the locking member and the fastening member, the cabinet door can be opened. Since the key needs to be used to operate the locking member to open the cabinet door first, and after closing the cabinet door, the key needs to be used to operate the locking member to fasten the fastening member, the operation process is cumbersome and troublesome. Moreover, if the key is lost, the cabinet door cannot be opened. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a concealed handle structure for a door body. By rotating its handle to drive the locking member to rotate to unlock, and after the handle returns to its original position, the locking portion of the locking member returns to its original position under the action of its own weight to achieve locking.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A concealed handle structure for a door body includes a handle, a box body, and a locking member; the handle includes a body, a buckle groove is provided on the body, and a trigger member extending downward is provided at the lower end of the body; the box body includes an installation groove for vertically rotating and installing the handle, and a through hole corresponding to the trigger member is provided at the lower part of the installation groove; the locking member is located at the lower part of the box body, the middle part of which can rotate up and down around a horizontal axis, a locking portion for cooperating with an external fastening member is provided at one end away from the through hole, and a swinging member for triggering downward swing when the trigger member rotates towards the locking portion is provided at one end corresponding to the through hole; the moment of the locking portion to the rotation axis of the locking member is greater than the moment of the swinging member to the rotation axis of the locking member.

[0006] Compared with the prior art, the concealed handle structure for a door body of the present invention has the following beneficial effects:

[0007] (1) The user rotates the handle within the installation groove, causing the trigger member to rotate and push the swing member downward. Since the swing member and the locking portion form a lever structure, as the swing member moves downward, the locking portion rotates upward and disengages from contact with the external fastening member, achieving the unlocking function. That is, the present invention utilizes the lever principle to achieve motion transmission through the connection between mechanical structure parts, enabling the locking member to move up and down along an arc trajectory to realize the function of locking and unlocking. The present invention is convenient for assembly and use, and has a simple production process;

[0008] (2) By setting the moment from the locking portion to the rotation axis of the locking member to be greater than the moment from the swing member to the rotation axis of the locking member, when the user resets the handle, without the pushing of the trigger member, the force state of the locking member returns to the locking state. One end of the locking portion rotates downward under its own weight and contacts the external fastening member, achieving the self-locking of the present invention and eliminating the trouble for the user to use a key to reset the lock fastener;

[0009] (3) The box body is provided with a through hole for the trigger member at the lower part of the handle. The through hole is used to limit the rotation range of the handle, thereby ensuring that the trigger member triggers the locking member within a preset range, and at the same time ensuring that the locking member swings a preset height after being triggered by the trigger member within a preset range and facilitating subsequent reset.

[0010] Further, the box body further includes a border arranged outside the installation groove, and the middle part of the locking member is rotatably connected to the border at the lower part of the box body.

[0011] The arrangement of the border can provide an installation position for the locking member, thereby hiding the locking member, avoiding the exposure of the locking member, and improving the aesthetics of the present invention.

[0012] Further, the border at the lower part of the box body is provided with a horizontally arranged shaft seat, and the middle part of the locking member is hinged to the shaft seat.

[0013] By setting the shaft seat, it is convenient for the installation of the locking member and improves the connection strength between the locking member and the box body.

[0014] Further, a limiting convex block is provided at the position corresponding to the lower part of the locking portion on the border at the lower part of the box body.

[0015] The arrangement of the limiting convex block, on the one hand, can prevent one end of the locking portion from rotating downward excessively under its own weight and affecting subsequent use, and on the other hand, can ensure that the locking portion contacts the external fastening member at a predetermined position.

[0016] Further, the included angle between the trigger member and the plane of the buckle groove opening is 5 - 50°.

[0017] Since the rotation stroke of the handle is limited, by adopting the above-mentioned setting method to set the trigger member, after the handle rotates a short rotation stroke, the trigger member can trigger the swing member, thereby improving the response speed. In addition, if the angle between the trigger member and the plane of the buckle groove opening is too large (exceeding 50°), after the handle completes the rotation stroke, the stroke of the trigger member triggering the swing member to swing downward is too small, and the upward swing stroke of the locking portion is not enough to unlock the locking portion and the buckling member.

[0018] Further, a step portion is provided on the side of the swing member facing the trigger member. The step portion gradually extends upward from the end away from the locking member to the end close to the locking member, and an arc transition is provided between the step regions on the step portion.

[0019] By adopting the above-mentioned setting method for the swing member, it is convenient for the trigger member to push the swing member downward by pushing the steps at different heights. In addition, the setting of the arc transition can make the trigger member rotate more smoothly when pushing the steps at different heights, and avoid the area between the steps from affecting the rotation of the trigger member.

[0020] Further, a slot is provided on the swing member, and one end of the locking member corresponding to the through hole is inserted into the slot to be connected to the swing member.

[0021] The above-mentioned setting method can facilitate the production personnel to quickly connect the locking member and the swing member, thereby reducing the assembly difficulty of the present invention.

[0022] Further, the area between the locking portion and the middle of the locking member is bent outward to form a bent portion.

[0023] For the cabinet body and the window body, since the above-mentioned components have a frame, by providing a bent portion on the locking member, it can be avoided that the frame interferes with the normal use of the present invention when the present invention is installed on the cabinet body and the window body.

[0024] Further, the distance from the swing member to the rotation axis of the locking member is shorter than the distance from the locking portion to the rotation axis of the locking member.

[0025] The above-mentioned setting method can make the locking portion located in the area outside the box body, avoid the box body interfering with the movement of the locking portion, and make the setting position of the external buckling member more flexible, so that the present invention is adapted to different types of cabinet bodies and window bodies.

[0026] Another object of the present invention is to provide a cabinet body applying the above-mentioned hidden door handle structure, including a door panel and a cabinet body. The side of the door panel is hinged to the cabinet body, the door panel can cover the opening of the cabinet body, the door panel is provided with the above-mentioned hidden door handle structure, and the cabinet body is provided with a buckling member corresponding to the locking portion of the hidden door handle structure.

[0027] Compared with the prior art, for the cabinet body of the present invention, a concealed door handle structure is provided between the door panel and the cabinet body. By rotating the handle by a certain angle to drive the locking member to rotate, the unlocking of the door panel and the cabinet body can be achieved (the locking member is separated from the buckling member). After rotating the handle back to its original position, the locking member resets under its own weight, and the locking of the door panel to the cabinet body can be achieved (the locking member is connected to the buckling member), with simple and convenient operation.

Detailed implementation mode

[0044] The following describes the implementation mode of the present invention with reference to the attached drawings:

[0045] Embodiment 1

[0046] See Figures 1 to 13 , a concealed door handle structure 20 in this embodiment includes a handle 1, a box body 6 and a locking part 13; the handle 1 includes a body 2, a buckle groove 3 is arranged on the body 2, and a trigger 4 extending downward is arranged at the lower end of the body 2; the box body 6 includes an installation groove 7 for vertically rotating and installing the handle 1 and an edge extension 8 arranged outside the installation groove 7, and a through hole 10 corresponding to the trigger 4 is arranged at the lower part of the installation groove 7; the locking part 13 is located at the lower part of the box body 6, the middle part of which can rotate up and down around a horizontal axis, a locking portion 14 for cooperating with an external fastening part 23 is arranged at one end far away from the through hole 10, and a swinging part 16 for triggering downward swing when the trigger 4 rotates towards the locking portion 14 is arranged at one end corresponding to the through hole 10; the moment of the locking portion 14 to the rotation axis of the locking part 13 is greater than the moment of the swinging part 16 to the rotation axis of the locking part 13.

[0047] See Figure 3 , the locking part 13 is a sheet structure.

[0048] See Figure 4 , rotating shafts 5 are respectively arranged at the upper and lower ends of the body 2, and shaft holes 12 corresponding to the rotating shafts 5 are arranged at the upper and lower ends of the installation groove 7.

[0049] See Figures 1 to 3 , the middle part of the locking part 13 is rotatably connected to the edge extension 8 at the lower part of the box body 6.

[0050] The arrangement of the edge extension 8 can provide installation for the locking part 13, thereby hiding the locking part 13 and avoiding the exposure of the locking part 13, improving the aesthetics of the present invention.

[0051] See Figure 5 , Figure 7 and Figure 8 , a horizontally arranged shaft seat 9 is arranged on the edge extension 8 at the lower part of the box body 6, and the middle part of the locking part 13 is hinged to the shaft seat 9.

[0052] By arranging the shaft seat 9, the installation of the locking part 13 is facilitated, and the connection strength between the locking part 13 and the box body 6 is improved.

[0053] See Figure 7And Figure 8 A limiting bump 11 is provided at a position corresponding to the lower part of the locking part 14 on the extension edge 8 at the lower part of the box body 6.

[0054] The setting of the limiting bump 11 can, on the one hand, prevent one end of the locking part 14 from rotating downward excessively under its own weight and affecting subsequent use, and on the other hand, ensure that the locking part 14 contacts the external fastening part 23 at a predetermined position.

[0055] See Figure 9 The included angle between the trigger part 4 and the opening plane of the buckle groove 3 is 5 - 50°.

[0056] Since the rotation stroke of the handle 1 is limited, for this reason, by adopting the above setting method to set the trigger part 4, after the handle 1 rotates a short rotation stroke, the trigger part 4 can trigger the swinging part 16, improving the response speed. In addition, if the included angle between the trigger part 4 and the opening plane of the buckle groove 3 is too large (exceeding 50°), after the handle 1 completes the rotation stroke, the downward swing stroke of the trigger part 4 triggering the swinging part 16 is too small, and the upward swing stroke of the locking part 14 is not enough to unlock the locking part 14 and the fastening part 23.

[0057] See Figure 10 A step part 18 is provided on the side of the swinging part 16 facing the trigger part 4. The step part 18 gradually extends upward from the end far from the locking part 13 to the end close to the locking part 13. An arc transition 19 is provided between the step areas on the step part 18.

[0058] The swinging part 16 adopts the above setting method, so that it is convenient for the trigger part 4 to push the swinging part 16 to move downward by pushing against steps of different heights. In addition, the setting of the arc transition 19 can make the trigger part 4 rotate more smoothly when pushing against steps of different heights, and avoid the area between the steps from affecting the rotation of the trigger part 4.

[0059] See Figure 10 A slot 17 is provided on the swinging part 16. One end of the locking part 13 corresponding to the through hole 10 is inserted into the slot 17 to be connected with the swinging part 16.

[0060] The above setting method can facilitate production personnel to quickly connect the locking part 13 and the swinging part 16, thereby reducing the assembly difficulty of the present invention.

[0061] See Figure 7 And Figure 8 The area between the middle parts of the locking part 14 and the locking part 13 is bent outward to form a bending part 15.

[0062] For the cabinet body and the window body, since the above components have a frame, by providing a bent portion 15 on the locking member 13, it is possible to prevent the frame from interfering with the normal use of the present invention when the present invention is installed on the cabinet body and the window body.

[0063] See Figure 7 and Figure 8 , the distance from the swing member 16 to the rotation axis of the locking member 13 is shorter than the distance from the locking portion 14 to the rotation axis of the locking member 13.

[0064] The above setting method can make the locking portion 14 located in the area outside the box body 6, prevent the box body 6 from interfering with the movement of the locking portion 14, and make the setting position of the external fastening member 23 more flexible, so that the present invention is adapted to different types of cabinet bodies and window bodies.

[0065] Compared with the prior art, a concealed door handle structure 20 of the present invention has the following beneficial effects:

[0066] (1) The user rotates the handle 1 in the installation groove 7 to make the trigger member 4 rotate and push the swing member 16 to move downward. Since the swing member 16 and the locking portion 14 form a lever structure, as the swing member 16 moves downward, the locking portion 14 rotates upward to disengage from the contact with the external fastening member 23, realizing the unlocking function. That is, the present invention utilizes the lever principle to realize the movement transmission through the connection between mechanical structure parts, making the locking member 13 move up and down in an arc trajectory to realize the function of locking and unlocking. The present invention is convenient for assembly and use, and the production process is simple;

[0067] (2) By setting the moment of the locking portion 14 to the rotation axis of the locking member 13 to be greater than the moment of the swing member 16 to the rotation axis of the locking member 13, when the user resets the handle 1, without the pushing of the trigger member 4, the force state of the locking member 13 returns to the locking state. One end of the locking portion 14 rotates downward under its own weight and contacts the external fastening member 23, realizing the self-locking of the present invention, saving the trouble for the user to use a key to reset the lock fastener;

[0068] (3) The box body 6 is provided with a through hole 10 for the trigger member 4 at the lower part of the handle 1. The rotation range of the handle 1 is limited by the through hole 10, so as to ensure that the trigger member 4 triggers the locking member 13 within a preset range, and at the same time ensure that the locking member 13 swings a preset height after being triggered by the trigger member 4 within a preset range and is convenient for subsequent reset.

[0069] Embodiment 2

[0070] See Figure 1 , Figures 11 to 14, Another object of the present invention is to provide a cabinet body applying the above-mentioned concealed door handle structure 20, which includes a door panel 21 and a cabinet body 22. The side of the door panel 21 is hinged to the cabinet body 22. The door panel 21 can cover the opening of the cabinet body 22. The door panel 21 is provided with the concealed door handle structure 20, and the cabinet body 22 is provided with a fastening member 23 corresponding to the locking portion 14 of the concealed door handle structure 20.

[0071] Compared with the prior art, in the cabinet body of the present invention, a concealed door handle structure 20 is provided between the door panel 21 and the cabinet body 22. The user can rotate the handle 1 by a certain angle to drive the locking member 13 to rotate, thereby unlocking the door panel 21 and the cabinet body 22 (the locking member 13 is separated from the fastening member 23). After rotating the handle 1 back to its original position, the locking member 13 returns to its original position under its own weight, thereby locking the door panel 21 to the cabinet body 22 (the locking member 13 is connected to the fastening member 23), and the operation is simple and convenient.
