Description

Technical Field

[0001] The utility model relates to the technical field of buffers, in particular to an anti-pinch buffer and a storage cabinet using the same. Background Art

[0002] A buffer, also commonly known as a damper or hydraulic buffer, is a device used to slow the closing speed of a door or lid. Typically installed at the hinge and top of a door, or at the hinge joint of a lid, the buffer absorbs the energy of closing through hydraulic or mechanical means, thereby reducing the impact of the closing action. This prevents the door panel from colliding with the cabinet or other objects, protecting the door and cabinet from damage. It also helps prevent fingers from being pinched by the sudden closing of the door, enhancing safety.

[0003] In the prior art, triangular connecting rods are a common buffer structure. For example, Chinese utility model patent publication number CN220604310U, "An Automatically Closable Digital Piano Lid," provides a buffer structure comprising a hinged base and a stand connected by a first hydraulic cylinder. The stand can be rotated up and down along the base via the first hydraulic cylinder. This buffer structure creates a triangular cavity between the base, stand, and first hydraulic cylinder when the buffer is open. When a user closes a cabinet door using this buffer, they may accidentally insert their fingers into this cavity, potentially causing a pinching of their fingers. This compromises the safety of the buffer and reduces the user experience. Utility Model Content

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] The present technical solution provides an anti-pinch buffer, comprising an outer articulated arm 1, an inner articulated arm 2, and a telescopic rod 3; the connecting end of the outer articulated arm 1 and the connecting end of the inner articulated arm 2 are hinged to each other, and the connecting end of the inner articulated arm 2 is located inside the connecting end of the outer articulated arm 1; the telescopic rod 3 is connected between the outer articulated arm 1 and the inner articulated arm 2, and the fixed end of the telescopic rod 3 is hinged to the mounting end of the outer articulated arm 1, and the movable end of the telescopic rod 3 is hinged to the middle part of the inner articulated arm 2;

[0038] The outer hinged arm 1 includes a first connecting plate 11 and a first protective plate 12. Two first protective plates 12 are provided, and the two first protective plates 12 are respectively provided on both sides of the first connecting plate 11. The first protective plate 12 and the two first protective plates 12 together enclose a first accommodating cavity.

[0039] The inner hinged arm 2 includes a second connecting plate 21 and a second protective plate 22. Two second protective plates 22 are provided, and the two second protective plates 22 are respectively provided on both sides of the second connecting plate 21. The second connecting plate 21 and the two second protective plates 22 together enclose a second accommodating cavity.

[0040] The first accommodating cavity and the second accommodating cavity are communicated with each other, and the telescopic rod 3 is always located inside the first accommodating cavity and the second accommodating cavity.

[0041] The buffer structure in the prior art is such that when the buffer is in the open state, a triangular cavity is formed between the base, the stand and the first hydraulic cylinder. When a user closes a cabinet door using the buffer, the user may accidentally insert their fingers into the cavity and cause their fingers to be pinched, which is not conducive to ensuring the safety of the buffer and reduces the user experience.

[0042] Therefore, in order to reduce the risk of users being pinched while ensuring the buffering effect of the buffer, this technical solution proposes an anti-pinch buffer, such as Figure 1-3 As shown, it includes an outer articulated arm 1, an inner articulated arm 2 and a telescopic rod 3, and the connecting end of the outer articulated arm 1 and the connecting end of the inner articulated arm 2 are hinged to each other, the fixed end of the telescopic rod 3 is hinged to the mounting end of the outer articulated arm 1, and the movable end of the telescopic rod 3 is hinged to the middle part of the inner articulated arm 2, so that the telescopic action of the telescopic rod 3 drives the outer articulated arm 1 to rotate relative to the inner articulated arm 2 with the hinge position as the axis.

[0043] Specifically, the outer hinged arm 1 and the inner hinged arm 2 of this solution are both composed of a connecting plate and a protective plate, and the first protective plate 12 of the outer hinged arm 1 and the two first protective plates 12 together form a first accommodating cavity, and the second connecting plate 21 and the two second protective plates 22 of the inner hinged arm 2 together form a second accommodating cavity, and the telescopic rod 3 is always located inside the first accommodating cavity and the second accommodating cavity. That is, when the anti-pinch buffer is in the closed state, as shown in FIG. Figure 3 As shown in (a), the telescopic rod 3 is completely accommodated in the first accommodating cavity and the second accommodating cavity, so that the user's fingers cannot be inserted into the triangular cavity surrounded by the first connecting plate 11, the second connecting plate 21 and the telescopic rod 3; when the anti-pinch buffer is in the open state, as shown in FIG. Figure 3 As shown in (b), the telescopic rod 3 is also completely accommodated in the first accommodating cavity and the second accommodating cavity, so that the user's fingers cannot be inserted into the triangular cavity surrounded by the first connecting plate 11, the second connecting plate 21 and the telescopic rod 3, thereby greatly reducing the risk of the user being pinched, which is conducive to ensuring the safety of the buffer and improving the user's experience.

[0044] It should be noted that the outer articulated arm 1 and the inner articulated arm 2 of this solution both include a connecting end and a mounting end, wherein the connecting end refers to the end for realizing the articulated installation, and the mounting end refers to the end used for installation with a structural member using an anti-pinch buffer.

[0045] To further explain, the width of the first protective plate 12 gradually decreases from the connecting end to the mounting end of the outer hinged arm 1 .

[0046] In a preferred embodiment of the present technical solution, the width of the first protective plate 12 is optimized to further ensure that the first protective plate 12 shields the triangular cavity formed by the first connecting plate 11, the second connecting plate 21 and the telescopic rod 3, which is more conducive to reducing the risk of pinching the user.

[0047] Further, the second protective plate 22 includes an integrally formed shielding section 221 and a material-saving section 222, wherein the shielding section 221 is disposed near the connection end of the inner hinged arm 2, and the material-saving section 222 is disposed near the mounting end of the inner hinged arm 2;

[0048] The edge of the shielding section 221 is an arc, and the middle of the arc bulges outward;

[0049] The width of the material-saving section 222 gradually decreases from the connecting end to the mounting end of the inner hinge arm 2 .

[0050] As a preference of the above embodiment, the shape of the second protective plate 22 is preferred to further ensure that the second protective plate 22 shields the triangular cavity surrounded by the first connecting plate 11, the second connecting plate 21 and the telescopic rod 3, which is more conducive to reducing the risk of pinching the user while saving materials.

[0051] To further explain, the maximum width of the first protective plate 12 is greater than the maximum width of the shielding section 221 .

[0052] In this way, the first accommodating cavity and the second accommodating cavity are always connected to each other, and a gap between the two accommodating cavities is prevented to increase the possibility of being clamped.

[0053] Further explanation: it also includes a protective cover 4, which is hinged to the outside of the connecting end of the outer articulated arm 1, and the hinge axis of the protective cover 4, the hinge axis of the connecting end of the outer articulated arm 1 and the hinge axis of the connecting end of the inner articulated arm 2 coincide with each other, and the connecting end of the outer articulated arm 1 and the connecting end of the inner articulated arm 2 are always located inside the protective cover 4.

[0054] In a more preferred embodiment of the present technical solution, a protective cover 4 is further provided on the outside of the connecting end of the outer hinged arm 1 and the connecting end of the inner hinged arm 2. The protective cover 4 blocks the gap between the outer hinged arm 1 and the inner hinged arm 2, which is more conducive to reducing the possibility of the user being pinched.

[0055] To further explain, the first protective plates 12 and the first protective plates 12 are perpendicular to each other, and the second connecting plate 21 and the second protective plate 22 are perpendicular to each other.

[0056] To further illustrate, the telescopic rod 3 includes a fixed sleeve 31 and a movable link 32, wherein the inner end of the movable link 32 is movably mounted inside the fixed sleeve 31, and the movable link 32 moves along the extension direction of the fixed sleeve 31;

[0057] The outer end of the fixed sleeve 31 is the fixed end of the telescopic rod 3 , and the outer end of the movable link 32 is the movable end of the telescopic rod 3 .

[0058] Preferably, the telescopic rod 3 of this solution can be a telescopic rod, a cylinder, etc., which is not limited here.

[0059] A storage cabinet, comprising the above-mentioned anti-pinch buffer, further comprising a cabinet body 5, a cover body 6, a first mounting member 7 and a second mounting member 8;

[0060] The top of the cabinet 5 is provided with an opening, the cabinet 5 and the cover 6 are hinged to each other by a hinge 9, and the cover 6 is used to open and close the opening of the cabinet 5;

[0061] The mounting end of the outer articulated arm 1 is connected to the lower surface of the cover body 6 through the first mounting member 7, and the mounting end of the outer articulated arm 1 and the first mounting member 7 are hinged to each other, and the hinge axis of the first mounting member 7, the hinge axis of the mounting end of the outer articulated arm 1, and the hinge axis of the fixed end of the telescopic rod 3 coincide with each other;

[0062] The mounting end of the inner hinged arm 2 is connected to the inner side wall of the cabinet 5 through the second mounting member 8 , and the mounting end of the inner hinged arm 2 and the second mounting member 8 are hinged to each other.
