Description

Anti-tilt device for cabinet and cabinet structure thereof

The present invention relates to an anti-tilt device for a cabinet and a cabinet structure thereof. The cabinet is used to store items and can be moved or positioned on the ground by wheels. The anti-tilt device is installed on the outer surface of the bottom of the cabinet to assist in moving or positioning the cabinet, especially to prevent the cabinet from tipping over when moving.

Conventional cabinets (such as general iron cabinets, welding cabinets or aluminum squeeze cabinets) are used to store items. In order to facilitate transportation, wheels are installed at the bottom of the cabinet. During the process of sliding and transporting the cabinet by wheels, if the wheels accidentally get stuck in the ground or hit the protrusions on the ground, it is very easy to tip forward, causing the cabinet body or the contents inside to fall heavily. Not only is it inconvenient to transport, but the cabinet body or the contents damaged after the heavy fall will also cause economic losses.

In particular, many current electronic industries use cabinets to house electronic computing equipment. Therefore, in addition to severe economic losses, the related operating functions and services of the electronic computing equipment will also be affected.

The present invention designs an anti-tilt device suitable for installation on a cabinet. The anti-tilt device can increase the angle causing the cabinet to tip over, making it difficult for the cabinet to tip over during sliding movement. The anti-tilt device can also assist the cabinet in sliding movement more smoothly and make the cabinet more stable when positioned at a fixed point. This is the solution of the present invention.

The invention is an anti-tilt cabinet, comprising a cabinet, a plurality of anti-tilt devices and a plurality of locking pieces. A bottom wheel is arranged on the bottom surface of the cabinet, an upper fixing area and a lower fixing area are arranged on the outer surface of the bottom of the cabinet, the upper fixing area has two upper fixing holes arranged longitudinally, the lower fixing area has two lower fixing holes arranged transversely, and the heights of the upper fixing holes are all higher than the heights of the lower fixing holes. Each of the anti-tilt devices has a first fixing member, a second fixing member and a connecting portion, the connecting portion is connected between the first fixing member and the second fixing member, the first fixing member has four first openings, the first openings are two lower openings arranged longitudinally and two upper openings arranged transversely, and the heights of the upper openings are higher than the heights of the lower openings, the second fixing member has at least one second opening, the horizontal distance from the second opening to the outer surface of the cabinet is an anti-tilt distance, and the second opening is used to fix an auxiliary wheel or a ground. The locking members are used to selectively lock the first fixing member to the upper fixing area or the lower fixing area to switch between two different use states. When the lower opening corresponds to the upper fixing hole, the locking pieces lock the first fixing piece to the upper fixing area, and the second opening can fix the auxiliary wheel; when the upper opening corresponds to the lower fixing hole, the locking pieces lock the first fixing piece to the lower fixing area, and the second opening can fix the ground.

Please refer to FIG. 1, which discloses a first embodiment of the anti-tilt device 10 of the present invention and a cabinet 4. The bottom of the cabinet 4 includes a bottom surface facing the ground 6 and an outer surface perpendicular to the bottom surface. The bottom surface is provided with adjacent positioning columns 41 and bottom wheels 42. The positioning columns 41 are used to position the cabinet 4 at a certain point, and the bottom wheels 42 are used to assist the cabinet 4 in moving. Four cabinet fixing holes 43 are provided on the outer surface of the cabinet 4, two of which are arranged longitudinally in an upper fixing area 45 of the cabinet 4 (as can be seen in FIG. 3). ), the other two cabinet fixing holes 43 are arranged horizontally in a lower fixing area 46 of the cabinet 4 (as can be seen in FIG. 6 ), and the four cabinet fixing holes 43 are used to combine and fix the anti-tipping device 10. More specifically, the four cabinet fixing holes 43 respectively have two upper fixing holes 431 and two lower fixing holes 432. The two upper fixing holes 431 are arranged vertically in the upper fixing area 45, and the two lower fixing holes 432 are arranged horizontally in the lower fixing area 46, and the height of each upper fixing hole 431 is higher than the height of each lower fixing hole 432. The anti-tilt device 10 includes a first fixing member 1, a second fixing member 2 and a connecting portion 3; one end of the first fixing member 1 is connected to one end of the second fixing member 2, so that the first fixing member 11 and the second fixing member 12 are vertical or nearly vertical, and the connecting portion 3 is connected between the first fixing member 1 and the second fixing member 2 to increase the support strength of the anti-tilt device 10 when it is tilted, so that the first fixing member 1 and the second fixing member 2 are maintained vertical and not easily deformed by external forces; this embodiment does not limit how the first fixing member 1, the second fixing member 2 or the connecting portion 3 are connected, such as welding, bonding or clamping, etc. As long as the first fixing member 1, the second fixing member 2 and the connecting portion 3 can be connected and fixed and not easily loosened, they all belong to the scope of protection of the present invention.

In this embodiment, four first openings 11 are provided on the surface of the first fixing member 1. The four first openings 11 are all circular holes. The circular first openings 11 are only for a locking member 44 to pass through. Two of the first openings 11 are arranged vertically in the middle of the first fixing member 1, and the other two first openings 11 are arranged horizontally above the first fixing member 1. More specifically, the four first openings 11 have two vertically arranged upper openings 111 and two horizontally arranged lower openings 112, and the height of each lower opening 112 is higher than the height of each upper opening 111. Please refer to Figures 2 to 4, which further disclose various viewing angles of the first embodiment of the anti-tipping device 10 after being assembled with the cabinet 4, especially the first fixing member 1 is assembled in the upper fixing area 45. The positions of the two upper openings 111 in the middle of the first fixing member 1 correspond to the positions of the upper fixing holes 431 located in the upper fixing area 45. One end of the two locking members 44 passes through the two upper openings 111 respectively and then locks with the two upper fixing holes 431, so that the first fixing member 1 is locked to the upper fixing area 45 of the cabinet 4. On the contrary, when the two locking members 44 are separated from the two upper fixing holes 431, the first fixing member 1 can be removed from the upper fixing area 45 of the cabinet 4, and the anti-tilt device 10 can be removed from the cabinet 4. That is, the anti-tilt device 10 can be locked to the cabinet 4 or removed from the cabinet 4 according to needs. In this embodiment, the locking member 44 may be a screw, and the cabinet fixing hole 43 may be a screw hole corresponding to the screw. As long as the locking member 44 is combined with the cabinet fixing hole 43 and will not be easily separated or dropped, this embodiment is not limited.

In addition, when the first fixing member 1 is assembled on the upper fixing area 45, the second fixing member 2 is used to assemble an auxiliary wheel 5. Two second openings 21 are provided on the end surface of the second fixing member 2 away from the first fixing member 1, and one of the second openings 21 is used to fix the auxiliary wheel 5. Specifically, the auxiliary wheel 5 has a fixing portion 51, and the fixing portion 51 can pass through the second opening 21 and then be screwed on the fixing portion 51 through a screw 52 to fix the auxiliary wheel 5 to the second fixing member 2. In this embodiment, the screw 52 can be a nut, and the fixing portion 51 can be a screw corresponding to the nut. As long as the combination between the screw 52 and the fixing portion 51 will not be easily separated, it belongs to the scope of protection of the present invention, and this embodiment does not limit it.

In this embodiment, the connecting portion 3 includes two connecting plates 31, which are respectively connected to the two side edges of the first fixing member 1 and the second fixing member 2, so that the anti-tipping device 10 forms a semi-open chamber 101 between the two connecting plates 31. The chamber 101 can prevent the lock 44 or the screw 52 from being exposed, and can effectively protect the lock 44 or the screw 52 from being loosened and damaged due to collision or friction.

Please refer to FIGS. 5 to 7. The difference from the above FIGS. 2 to 4 is that the first fixing member 1 is assembled in the lower fixing area 46. The positions of the two lower openings 112 above the first fixing member 1 correspond to the positions of the lower fixing holes 432 located in the lower fixing area 46. One end of the two locking members 44 passes through the corresponding two lower openings 112 respectively, and then locks with the corresponding two lower fixing holes 432, so that the first fixing member 1 is locked in the lower fixing area 46 of the cabinet 4; conversely, when the two locking members 4 are separated from the two lower fixing holes 432, the first fixing member 1 can be removed from the lower fixing area 46 of the cabinet 4, and the anti-tipping device 10 can be removed from the cabinet 4. That is, the anti-tilt device 10 can be locked to the cabinet 4 or removed from the cabinet 4 as needed.

In addition, when the first fixing member 1 is assembled in the lower fixing area 46, the second fixing member 2 is attached to a ground 6, and the position of another second opening 21 on the surface of the second fixing member 2 corresponds to the position of a ground fixing hole 61 on the ground 6, and then one end of a ground coupling member 62 passes through the second opening 21 and is locked with the ground fixing hole 61 to fix the second fixing member 2 to the ground 6. In this embodiment, the ground coupling member 62 can be a screw, and the ground fixing hole 61 can be a screw hole corresponding to the screw. As long as the combination between the ground coupling member 62 and the ground fixing hole 61 will not be easily separated, it belongs to the scope of protection of the present invention, and this embodiment is not limited. In addition, the chamber 101 formed between the two connecting plates 31 can also prevent the ground coupling member 62 from being exposed, which can effectively protect the ground coupling member 62 from being easily loosened or damaged by collision or friction.

As shown in FIGS. 1 to 7 above, it can be seen that when the anti-tipping device 10 is assembled in the upper fixing area 45 of the cabinet 4, it is used to assemble the auxiliary wheel 5; when the anti-tipping device 10 is assembled in the lower fixing area 46 of the cabinet 4, it is used to assemble on the ground 6, thereby switching between two different implementation states. As shown in Figures 1 to 4, when the second fixing member 2 is equipped with the auxiliary wheel 5, the cabinet 4 can slide through the bottom wheel 42 and the auxiliary wheel 5 installed by the anti-tilt device 10, so as to move the cabinet 4 in a time-saving and labor-saving manner, and prevent the cabinet 4 from tipping over during the movement; as shown in Figures 5 to 7, when the second fixing member 2 is fixed to the ground 6, the cabinet 4 can be fixed to the ground 6 through the positioning column 41 of the cabinet 4 and the anti-tilt device 10, so as to achieve the effect of anti-tilt and anti-seismic.

Please refer to FIG. 8 simultaneously. In this embodiment, the cabinet 4 can be a welding cabinet or an aluminum extrusion cabinet and is a rectangular parallelepiped. The cabinet 4 has four corners at the bottom (only three corners are shown due to visual angle obstruction). The front and back sides are wider and are more prone to tipping than the narrower left and right sides. Therefore, four anti-tip devices 10 are respectively provided at the four corners at the bottom of the cabinet 4. Specifically, the four anti-tilt devices 10 include two first anti-tilt devices 10A and two second anti-tilt devices 10B, and the two first anti-tilt devices 10A are arranged on the front of the outer surface of the bottom of the cabinet 4 (upper fixing area 45 or lower fixing area 46), and the two second anti-tilt devices 10B are arranged on the back of the outer surface of the bottom of the cabinet 4 (upper fixing area 45 or lower fixing area 46), and the positions of the two first anti-tilt devices 10A correspond to the positions of the two second anti-tilt devices 10B. The above description does not limit the number or position of the anti-tilt devices 10 arranged in the cabinet 4, for example: there can be four anti-tilt devices 10, which are installed at the four corners of the cabinet 4.

Please refer to Figure 9A. When the cabinet 4 is not equipped with the anti-tilt device 10, the tilting support point P1 of the cabinet 4 is located on the outer surface of the cabinet 4. After the anti-tilt device 10 is installed, the tilting support point P2 of the cabinet 4 is horizontally moved to the second opening (not shown in the figure, details can be seen in Figure 4) of the fixed auxiliary wheel 5 to extend the horizontal distance from the cabinet gravity center point P3 of the cabinet 4 to the tilting support point of the cabinet 4. It should be noted that in practice, the position of the cabinet gravity center point P3 of the cabinet 4 will deviate due to the objects contained in the cabinet 4. However, for the convenience of explanation and understanding, in this embodiment, the cabinet gravity center point P3 of the cabinet 4 is set at the center of the cabinet 4.

；請參閱第9C圖，圖中揭示的機櫃4裝設防傾倒裝置10，在本實施例中，機櫃重心點P3至機櫃4底面的垂直距離L2係為650cm，機櫃重心點P3至第二開孔的傾斜支點P2的第二水平距離L4係為350cm(相當於第一水平距離L3的250cm加上防傾倒距離L1的100cm)，計算加裝防傾倒裝置10時之傾角R2得出

。因此，證明加裝防傾倒裝置10之後，機櫃4由外側表面往外延長了一段防傾倒距離L1，進一步地加大防傾倒角度，且防傾倒角度愈大，則機櫃4愈不容易傾倒。 Therefore, the distance between the tilting support point P1 and the tilting support point P2 can be defined as an anti-tilting distance L1, and an anti-tilting angle can be calculated from the anti-tilting distance L1. The anti-tilting angle refers to the maximum angle at which the cabinet 4 does not tilt when tilted. In other words, the cabinet 4 will not tilt as long as the tilting angle is less than the anti-tilting angle. The anti-tilt angle is calculated as follows: Please refer to FIG. 9B, in which the cabinet 4 is not equipped with the anti-tilt device 10 (in order to avoid confusion with FIG. 9C, the anti-tilt device 10 is drawn as a chain in FIG. 9B). In this embodiment, it is assumed that the vertical distance L2 from the center of gravity P3 of the cabinet to the bottom surface of the cabinet 4 is 650 cm, and the first horizontal distance L3 from the center of gravity P3 of the cabinet to the tilting support point P1 on the outer surface of the cabinet 4 is 250 cm. The tilt angle R1 when the anti-tilt device 10 is not installed is calculated to obtain

; Please refer to FIG. 9C , which discloses that the cabinet 4 is equipped with an anti-tilt device 10. In this embodiment, the vertical distance L2 from the cabinet center of gravity P3 to the bottom of the cabinet 4 is 650 cm, and the second horizontal distance L4 from the cabinet center of gravity P3 to the tilting support point P2 of the second opening is 350 cm (equivalent to the first horizontal distance L3 of 250 cm plus the anti-tilt distance L1 of 100 cm). The tilt angle R2 when the anti-tilt device 10 is installed is calculated to obtain

Therefore, it is proved that after the anti-tilt device 10 is installed, the cabinet 4 is extended from the outer surface to the outside by an anti-tilt distance L1, further increasing the anti-tilt angle, and the larger the anti-tilt angle is, the less likely the cabinet 4 is to tip over.

Please refer to Figure 10, which shows the second embodiment of the anti-tilt device 10. The difference from the first embodiment is that the first opening 11 is a single, straight long hole, which can allow multiple locking components 44 to pass through at the same time. In this way, the straight long first opening 11 is not limited by the hole diameter, and the height of the anti-tilt device 10 can be fine-tuned conveniently.

Please refer to Figure 11, which discloses the third embodiment of the anti-tilt device 10. The difference from the first embodiment is that the second opening 21 is a single elliptical hole, which is only for a fixing part 51 or a ground coupling member 62 to pass through. When the second fixing member 2 is respectively assembled with the auxiliary wheel 5 or the ground 6, the same second opening 21 is used for sharing.

Please refer to Figure 12, which discloses the fourth embodiment of the anti-tilt device 10. The difference from the first embodiment is that the connecting portion 3 includes a single connecting plate 31, and the connecting plate 31 is used to connect the two adjacent surfaces of the first fixing member 1 and the second fixing member 2. In this way, the single connecting plate 31 uses less material and only needs one processing to connect with the first fixing member 1 and the second fixing member 2, which is easier to manufacture.

Although the anti-tilt device 10 has a variety of implementation forms, no matter what form it is, the first fixing member 1, the second fixing member 2 or the connecting portion 3 can be made of a flat metal material. The rigidity of the metal material can effectively provide support strength, and the flat plate shape is easy to manufacture. This embodiment does not limit the material and shape of the first fixing member 1, the second fixing member 2 or the connecting portion 3. As long as they can be joined and provide support strength, they should belong to the scope of the first fixing member 1, the second fixing member 2 or the connecting portion 3.

In summary, the anti-tilt device 10 installed on the cabinet 4 does increase the anti-tilt angle, making it difficult for the cabinet 4 to tip over, and effectively preventing important equipment in the cabinet 4 from being hit by tipping, thereby causing significant economic losses.

The above-mentioned embodiments are only some of the preferred embodiments of the present invention, but they are not used to limit the present invention. Any person familiar with this technical field with common knowledge, after understanding the above-mentioned technical features and embodiments of the present invention, and making equal changes or modifications within the spirit and scope of the present invention, still falls within the scope of the present invention, and the scope of patent protection of the present invention shall be subject to the definition of the claim items attached to this specification.
