Description

Technical Field

[0001] The utility model relates to the technical field of door body limiting, and more specifically to a door body limiting device. Background Art

[0002] At present, for products such as beauty refrigerators, small refrigerators, and constant temperature wine cabinets on the market, there are mainly two types of limiting structures for the door body: the "unlimited limit" structure and the "100° limit" structure. Among them, the door body of the "100° limit" structure is limited by the beauty refrigerator product itself. The volume of the door body is not very large. When opening the door body, the maximum rotation distance of the door is short. When opening the door with one hand, due to the rotation distance, the palm force is not consumed completely due to the short operation distance and is blocked by the "100° limit" structure, resulting in a feeling of pinching the hand and poor user experience; moreover, the limit between the door body and the door shaft will bear the remaining force of extrusion, and the door shaft structure of the door body will be damaged after long-term use; at the same time, the opening limit is small, and affected by the angle, the inner door liner and the inner box liner cannot be presented in the user's field of vision at the same time, and the line of sight needs to be moved at an angle to observe the inside.

[0003] The opening and closing angle of the "unlimited limit" structure is limited by the cooperation of the door shaft position of the door body and usually can reach 180°. The inner door liner and the inner box liner can appear in the field of vision at the same time. However, since the door body has no limiting structure, after the door body is opened by hand, the door body will open due to the inertia obtained by the hand opening and the placement inclination angle and other problems, and the door body will open until it collides with the box body, which will scratch the door body and the box body and affect the appearance of the product; at the same time, due to the lack of limit, there is a risk of pinching the hand when the door body collides with the box body. In order to avoid damage to the door body, Chinese Patent No. CN219241633U discloses a door body limiting structure. Although this prior art restricts the opening angle of the door body to less than 180° by using the baffle part, avoiding the problem of easy damage to the door body, it is a limiting structure fixed on the door body and needs to cooperate with a specific door bottom plate structure, with poor applicability and non-adjustability, resulting in inconvenience for users.

[0012] In a preferred technical solution, the fan-shaped unfolding angle of the fan-shaped limit part is 140 degrees, so that the opening limit angle of the door body is 130 degrees, which is more in line with the ergonomics of human body opening the door and user usage habits.

[0013] In a preferred technical solution, at least two convex strips are provided at both ends of the inner side of the arc-shaped clamping wall to further strengthen the friction with the door shaft and make the installation more firm.

[0014] In a preferred technical solution, the arc-shaped clamping wall is made of hard material, and the convex strip is made of soft material. The door body limit device in this technology can be firmly fixed on the door shaft through the cooperation of the hard material clamping wall and the soft material convex strip.

[0027] Refer to Figures 1-7 Describe a door body limiting device 3 according to an embodiment of the present utility model.

[0028] In one embodiment, as Figures 1-6 shown, a door body limiting device 3 is detachably mounted on the door shaft 2 of the door body 1. The door body limiting device 3 includes an arc-shaped clamping wall 31 and a sector-shaped limiting part 32. The sector-shaped limiting part 32 is arranged at one end of the outer side surface of the arc-shaped clamping wall 31; preferably, the sector-shaped limiting part 32 is a hollow structure, which is lightweight while meeting the strength of the components and reduces costs.

[0029] The inner side surface of the arc-shaped clamping wall 31 is used for clamping and fixing on the door shaft 2, and convex strips 33 are arranged at both ends of the inner side surface of the arc-shaped clamping wall 31; one end of the arc-shaped clamping wall 31 far from the sector-shaped limiting part 32 extends inward to form a clamping part of the arc-shaped clamping wall 31. The included angle between the clamping part and the contact surface of the door shaft 2 is an acute angle, and the contact surface of the door shaft 2 is the tangent plane at the contact position between the door shaft 2 and the clamping part.

[0030] Among them, the arc-shaped clamping wall 31 extends inward to form a clamping part, and the included angle between the clamping part and the contact surface of the door shaft 2 is an acute angle, that is, the clamping angle between the arc-shaped clamping wall 31 and the door shaft 2 is an acute angle, so that the arc-shaped clamping wall 31 can be firmly fixed on the door shaft 2. The arc-shaped clamping wall 31 and the sector-shaped limiting part 32 are of an integrally formed structure. The door shaft 2 is the hinge shaft of the door body 1 and the box body 4, and can be an upper door shaft and a lower door shaft.

[0031] Furthermore, at least two convex strips 33 are provided at both ends of the inner side surface of the arc-shaped clamping wall 31, that is, the number of convex strips 33 provided at each end can be 2, 3 or even more, so as to further strengthen the frictional force with the door shaft 2 and make the installation more firm. Preferably, two convex strips 33 are provided at each end of the inner side surface of the arc-shaped clamping wall 31.

[0032] In this embodiment, the arc-shaped clamping wall 31 is made of a hard material, and the convex strip 33 is made of a soft material. The above-mentioned door body limiting device 3 can be firmly fixed on the door shaft 2 through the cooperation of the clamping wall made of hard material and the convex strip 33 made of soft material.

[0033] A door body limiting device 3 provided in the above embodiment is an externally attached component that can be manually disassembled and installed, and can realize the switching of the door body 1 between being limited and unlimited; at the same time, the door body limiting device 3 can be clamped on the door shaft 2 from the side, and is convenient to install and remove. During specific implementation, the arc-shaped clamping wall 31 is fixed on the door shaft 2 by clamping, the inner side surface of the arc-shaped clamping wall 31 is attached to the door shaft 2, the fan-shaped limiting portion 32 rotates synchronously with the door body 1, and the two contact surfaces on both sides of its upper arc surface are in contact with the door body 1 on one side and contact the box body 4 as the door body 1 rotates on the other side, so as to fix the maximum opening and closing angle of the door body 1 and achieve the limiting purpose.

[0034] At the same time, the convex strip 33 can be made of a soft material, the arc-shaped clamping wall 31 can be made of an elastic hard material, the arc-shaped clamping wall 31 is in interference fit with the door shaft 2, the convex strip 33 is deformed by extrusion, and is closely attached to the door shaft 2 to increase the frictional force. With the resilience of the material of the arc-shaped clamping wall 31 itself, it can be firmly fixed on the door shaft 2 to avoid falling off due to impact when opening the door; at the same time, the soft convex strip 33 can also protect the appearance of the door shaft 2.

[0035] In this embodiment, as Figure 7 shown, the door body contact surface 321 of the fan-shaped limiting portion 32 and the door body 1 is a square surface, which can better fit with the door body 1 and cooperate with the door body 1 to apply force; the box body contact surface 322 of the fan-shaped limiting portion 32 and the box body 4 is a long strip-shaped arc surface, which reduces the contact area while ensuring stable contact, and is beneficial to protecting the appearance of the product. Further, all the edges of the fan-shaped limiting portion 32 are rounded corners to ensure user safety.

[0036] In this embodiment, the fan-shaped limiting portion 32 is fan-shapedly unfolded with the axis of the door shaft 2 as the center of the circle, and the fan-shaped limiting portion 32 controls the opening limiting angle of the door body 1 with its fan-shaped unfolding angle. Since the fan-shaped limiting portion 32 and the door shaft 2 are coaxial and rotate synchronously, when the door body 1 rotates and opens, it drives the fan-shaped limiting portion 32, realizing the integration of the door body 1 and the fan-shaped limiting portion 32. The fan-shaped limiting portion 32, as an extension of the door body 1, can achieve the limiting purpose; at the same time, the arc surface structure of the fan-shaped limiting portion 32 can cooperate with the outer surface of the door body 1, increasing the aesthetic degree of the product.

[0037] In this embodiment, the fan-shaped limiting portion 32 has a fan surface expansion angle of 100 degrees to 150 degrees, and the fan-shaped limiting portion 32 can control the limiting angle at which the door body 1 is opened through the angle of its fan-shaped expansion.

[0038] Furthermore, the fan surface expansion angle of the fan-shaped limiting portion 32 is 140 degrees, so that the limiting angle at which the door body 1 is opened is 130 degrees. The limiting angle of 130° at which the door body 1 is opened is more in line with the ergonomics of human body opening the door and the user's usage habits, and can avoid the phenomenon of "pinching hands" when the opening and closing angle is too small, and the collision between the door body 1 and the box body 4 caused by no limit, which affects the appearance.

[0039] The other components and operations of the door body limiting device according to the embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.
