[0034] In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0035] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] Combine the following Figures 1 to 4 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0038] See also Figures 1 to 4 The cabinet includes a cabinet door 1 and a cabinet body 2. The cabinet door 1 is hinged to the cabinet body 2 using a door hinge or a hinge. The experimenter can easily open the cabinet door 1 to take out items.

[0039] An embodiment of the utility model provides a handle device for a cabinet door, which can be installed on a cabinet door 1 . The handle device for a cabinet door includes a base 100 and a movable handle 200 .

[0040] The base 100 is fixed on the cabinet door 1 , and a through hole 110 is provided on the base 100 , and the through hole 110 passes through the inside of the cabinet body 2 .

[0041] The movable handle 200 is hinged to the base 100, and the movable handle 200 can pass through the through hole 110. The first end of the movable handle 200 is outside the cabinet door 1, and the second end of the movable handle 200 is inside the cabinet door 1. When the experimenter swings the first end of the movable handle 200, the second end of the movable handle 200 also swings, so that the movable handle 200 has a closed state and an open state.

[0042] In the closed state, the movable handle 200 is engaged with the cabinet body 2. Since the movable handle 200 is fixed to the cabinet door 1 through the base 100, the cabinet door 1 cannot be opened (ie, the cabinet door 1 is locked with the cabinet body 2).

[0043] In the open state, the movable handle 200 is separated from the cabinet body 2, and the cabinet door 1 can be opened.

[0044] It can be understood that the handle device for a cabinet door provided in the embodiment of the utility model is provided by arranging a base 100 on the cabinet door 1, and a through hole 110 is provided on the base 100. The movable handle 200 is hinged to the base 100 and passes through the through hole 110, so that the movable handle 200 can be engaged with or separated from the cabinet body 2, that is, the cabinet door 1 can be locked with the cabinet body 2 through the movable handle 200. When the experimenter takes out items from the cabinet, the cabinet door 1 will not be opened by mistake, and the items in the cabinet can be prevented from being exposed, thereby reducing unnecessary troubles for the experimenter and improving work efficiency.

[0045] Specifically, the handle device further includes a fixing buckle 300 , which is disposed on the cabinet 2 . In this embodiment, the fixing buckle 300 can be fixed in the cabinet 2 , so that the second end of the movable handle 200 can contact the fixing buckle 300 .

[0046] In the closed state, the movable handle 200 is engaged with the fixing buckle 300 , and at this time, the cabinet door 1 is locked with the cabinet body 2 .

[0047] In the open state, the movable handle 200 is separated from the fixed buckle 300, and at this time, the cabinet door 1 and the cabinet body 2 can be opened. The fixed buckle 300 is arranged in the cabinet body 2, so that when the movable handle 200 is engaged with the cabinet body 2 (closed state), it does not need to contact the cabinet body 2, but only needs to be engaged with the fixed buckle 300, thereby making the structure of the cabinet body 2 simpler, and the cabinet body 2 does not need to be complicatedly improved to match the movable handle 200.

[0048] Further, in some embodiments of the present invention, the fixing buckle 300 includes a buckling portion 310, the buckling portion 310 is wedge-shaped, and a slope can be set on the buckling portion 310 to form a wedge shape, and this slope is a joint surface, and the movable handle 200 is provided with a joint portion 210 matching the buckling portion 310. In this case, the joint portion 210 is also a slope, and the slope of the joint portion 210 is engaged with the slope of the buckling portion 310. The buckling portion 310 in the shape of a wedge can make it more convenient for the movable handle 200 to switch between the closed state and the open state.

[0049] In some embodiments of the present invention, the movable handle 200 includes a hand-pull section 220 and a joint section 230 connected to each other, the hand-pull section 220 and the joint section 230 are arranged at an angle, the joint section 230 is hinged to the base 100, and the joint portion 210 is arranged at the joint section 230. The hand-pull section 220 and the joint section 230 are arranged at an angle to avoid the hand-pull section 220 protruding too much from the cabinet door 1, thereby preventing safety hazards such as collision and scratches, thereby improving the safety of the device.

[0050] In some embodiments of the present invention, in order to reset the movable handle 200 from an open state to a closed state, thereby reducing the workload of experimenters and improving work efficiency, the device further includes an elastic member 400, which abuts against the movable handle 200 and the base 100 respectively, and can reset the movable handle 200 from an open state to a closed state.

[0051] Specifically, the elastic member 400 can be arranged at the hinge of the movable handle 200 and the base 100, so that the elastic member 400 can better abut against the movable handle 200 and the base 100, increase the compression of the elastic member 400, improve the resilience, and enable the movable handle 200 to be better reset.

[0052] Furthermore, in order to save the experimenter more effort when opening the cabinet door, in some embodiments of the present invention, the elastic member 400 can be set at the hinge between the joint section 230 and the base 100, making full use of the principle of lever saving effort.

[0053] Of course, the elastic member 400 may be a torsion spring. The torsion spring suspension has a light weight, a simple structure, and does not require lubrication. In addition, the elastic energy stored per unit volume is relatively large, which further enables the movable handle 200 to be reset more completely and reduces the workload of the experimenter.

[0054] In some embodiments of the utility model, the base 100 is provided with an avoidance groove 120, which can avoid the movable handle 200. The avoidance groove 120 is a groove, and when the movable handle 200 switches between the closed state and the open state, the hand-pull section 220 of the movable handle 200 can be confined in the groove, further preventing the hand-pull section 220 from protruding out of the cabinet door 1, thereby improving the safety of the device.

[0055] In some embodiments of the present invention, the angle between the hand-pull section 220 and the joint section 230 is a right angle. When the joint section 230 is engaged with the fixing buckle 300, the hand-pull section 220 is parallel to the cabinet door 1, which ensures safety and makes the cabinet more beautiful.
