[0033] See also Figures 1 to 3The utility model discloses an enhanced shelf, including a frame body 100, a bracket 200, a shelf 300 and a cross plate 500, wherein the frame body 100 includes a front left support column 110, a front right support column 120, a rear left support column 130 and a rear right support column 140 which are distributed in a rectangular shape; the bracket 200 includes a left side plate 230 and a right side plate 240, and the rear ends of the left side plate 230 and the right side plate 240 are respectively hung on the rear left support column 130 and the rear right support column 140; the shelf 300 includes a front left support column 110, a front right support column 120, a rear left support column 130 and a rear right support column 140; the shelf 300 includes a front left support column 110, a front right support column 120, a rear left support column 130 and a rear right support column 140; the shelf 300 includes a front right support column 120, a rear right ...10, a front right support column 120, a rear left support column 130 and a rear right support column 140; the shelf 300 includes a front right support column 110, a front right support column 120, a rear left support column 13 00 is straddled on the left plate 230 and the right plate 240 through a front-rear sliding mechanism 400, so that the shelf 300 can be extended and retracted along the front-rear direction on the bracket 200; the left and right ends of the horizontal plate 500 are respectively connected to the front left support column 110 and the front right support column 120 through two side bolt mechanisms 700, and the front ends of the left plate 230 and the right plate 240 can respectively abut against the left and right ends of the horizontal plate 500 to support the front ends of the left plate 230 and the right plate 240.
[0034] The rear left support column 130 and the rear right support column 140 of the frame body 100 support the left side plate 230 and the right side plate 240 of the bracket 200. The shelf 300 is supported on the left side plate 230 and the right side plate 240 by the front and rear sliding mechanism 400. The shelf 300 is used to store items.
[0035] The forward and backward sliding mechanism 400 can make the shelf 300 extend and retract on the bracket 200. When the shelf 300 extends to the front stop point, it is convenient to place items on the shelf 300 or remove items from the shelf 300. In particular, for shelves with multiple layers of brackets 200 and multiple layers of shelves 300, the smaller the distance between the two layers of brackets 200 / shelves 300 distributed up and down, the more layers of brackets 200 / shelves 300 can be set on the frame 100, and the greater the load capacity of the shelf. The smaller the distance between the two layers of brackets 200 / shelves 300 distributed up and down, the more inconvenient it is to place items on the shelf 300 or remove them from the shelf 300. The shelf 300 that can extend forward can just solve the problem of how to conveniently place items on or remove them from the shelf 300.
[0036] The left and right ends of the cross plate 500 are connected to the front left support column 110 and the front right support column 120 respectively through two side bolt mechanisms 700, the front end of the left plate 230 and the front end of the right plate 240 are respectively against the left and right ends of the cross plate 500, the front left support column 110 and the front right support column 120 support the cross plate 500, and the cross plate 500 supports the front end of the left plate 230 and the front end of the right plate 240, so that the front and rear ends of the left plate 230 and the front and rear ends of the right plate 240 are both subjected to force. , the load-bearing capacity of the bracket 200 is improved, the front and rear widths of the bracket 200 and the shelf 300 can be set larger, the shelf 300 can bear greater gravity and more items, so that the torque applied to the connection between the rear end of the left side plate 230 and the rear left support column 130 and between the rear end of the right side plate 240 and the rear right support column 140 is smaller, thereby avoiding the connection between the rear end of the left side plate 230 and the rear left support column 130 and between the rear end of the right side plate 240 and the rear right support column 140 from being damaged.
[0037] See also Figure 1 and Figure 3 In some embodiments, the rear ends of the left plate 230 and the right plate 240 are both provided with hooks 250, and the rear left support column 130 and the rear right support column 140 are both provided with a plurality of hanging holes 150 distributed in the up-down direction. The hook 250 at the rear end of the left plate 230 is hung on the hanging hole 150 on the rear left support column 130, and the hook 250 at the rear end of the right plate 240 is hung on the hanging hole 150 on the rear right support column 140, thereby achieving that the rear ends of the left plate 230 and the right plate 240 are hung on the rear left support column 130 and the rear right support column 140 respectively.
[0038] It is understandable that both the rear left support column 130 and the rear right support column 140 are hollow structures, and the hanging hole 150 on the rear left support column 130 is flush with the hanging hole 150 on the rear right support column 140, so that the rear end of the left plate 230 and the rear end of the right plate 240 can be on the same level. The number of hooks 250 on the left plate 230 can be multiple, and the multiple hooks 250 on the left plate 230 are simultaneously hung on the multiple hanging holes 150 on the rear left support column 130, and the number of hooks 250 on the right plate 240 can be multiple, and the multiple hooks 250 on the right plate 240 are simultaneously hung on the multiple hanging holes 150 on the rear right support column 140, thereby improving the connection strength between the rear end of the left plate 230 and the rear left support column 130, and improving the connection strength between the rear end of the right plate 240 and the rear right support column 140.
[0039] Specifically, the hanging hole 150 on the rear left support column 130 is disposed on the front side of the rear left support column 130 , and the hanging hole 150 on the rear right support column 140 is disposed on the front side of the rear right support column 140 .
[0040] The rear end of the left plate 230 and the rear end of the right plate 240 are connected via a connecting rod.
[0041] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the front left support column 110 and the front right support column 120 are each provided with a plurality of sockets 160 distributed in the up-down direction, and the side bolt mechanism 700 includes a mounting block 710 and a latch 720, the mounting block 710 is connected to the cross plate 500, and the left and right ends of the mounting block 710 are each provided with an ear plate 711, and the two ear plates 711 are each provided with a through hole, and the axial direction of the through hole is the left-right direction, and one end of the latch 720 is passed through the two through holes to realize the connection between the latch 720 and the mounting block 710.
[0042] The latch 720 is pushed to move along its axial direction, and the latch 720 can be inserted into or out of the insertion hole 160. When the latch 720 is inserted into the insertion hole 160, the cross plate 500 is connected with the front left support column 110 / front right support column 120. The front left support column 110 and the front right support column 120 can both support the latch 720, thereby supporting the front end of the left side plate 230 and the front end of the right side plate 240.
[0043] Specifically, the insertion hole 160 on the rear left support column 130 is disposed on the right side of the rear left support column 130 , and the insertion hole 160 on the rear right support column 140 is disposed on the left side of the rear right support column 140 .
[0044] The frame 100 further includes a bottom frame, to which the lower ends of the front left support column 110, the front right support column 120, the rear left support column 130, and the rear right support column 140 are all connected. The front left support column 110 and the rear left support column 130, the rear left support column 130 and the rear right support column 140, and the front right support column 120 and the rear right support column 140 are all connected together by a tie rod.
[0045] See also Figure 4 In some embodiments, the side bolt mechanism 700 further includes an elastic member 730, a cam 740 is provided in the area where the latch 720 is located between the two ear plates 711, and the elastic member 730 is provided between the cam 740 and one of the ear plates 711. The elastic member 730 drives the latch 720 toward the direction of the insertion hole 160. In a natural state, one end of the latch 720 remains inserted into the insertion hole 160, thereby preventing the latch 720 from accidentally exiting the insertion hole 160, thereby preventing the front end of the left plate 230 and the front end of the right plate 240 from accidentally losing support.
[0046] In some of the embodiments, the latch 720 includes a connected plug-in portion 721 and an operating portion 722, the plug-in portion 721 and the operating portion 722 are L-shaped, the plug-in portion 721 passes through two through holes, the mounting block 710 is provided with two blocking columns 712 in the area between the two ear plates 711, the two blocking columns 712 are distributed front and back and both extend downward, the plug-in portion 721 is passed through the two blocking columns 712, the number of the convex blocks 740 is two, the two convex blocks 740 are coaxially arranged, an L-shaped groove is provided on the cross plate 500, the notch of the L-shaped groove faces downward, a blocking hook portion is provided on the side wall of the L-shaped groove close to the plug-in portion 721, and the operating portion 722 can be hung on the blocking hook portion.
[0047] When the operating portion 722 is hung on the blocking hook portion, the plug-in portion 721 is inserted into the insertion hole 160, and the two protruding stops 740 are located between the blocking column 712 and the other ear plate 711; when the operating portion 722 is not hung on the blocking hook portion, the operating portion 722 can be driven to move in the direction away from the insertion hole 160, and the two protruding stops 740 will respectively abut against the two blocking columns 712, resulting in the operating portion 722 and the plug-in portion 721 being unable to continue to move in the direction away from the insertion hole 160. The operating portion 722 needs to be swung downward, and the two protruding stops 740 can pass through the gap between the two blocking columns 712, thereby continuing to drive the operating portion 722 and the plug-in portion 721 to move in the direction away from the insertion hole 160, and the plug-in portion 721 withdraws from the insertion hole 160, entering to unlock the side bolt mechanism 700; the operating portion 722 can be operated in reverse to insert the plug-in portion 721 into the insertion hole 160, thereby locking the side bolt mechanism 700.
[0048] The arrangement of the L-shaped groove, the blocking hook portion, the two blocking columns 712 and the two convex blocks 740 enables the side bolt mechanism 700 to have an anti-foolproof function. The unlocking and locking of the side bolt mechanism 700 both require the rotation of the fixed operating portion 722 .
[0049] Specifically, the elastic member 730 is a spring, and the elastic member 730 is sleeved on the plug-in portion 721 . Two ends of the elastic member 730 respectively abut against the convex stop 740 and one of the ear plates 711 .
[0050] The front-rear sliding mechanism 400 is a slide rail. There are two front-rear sliding mechanisms 400, and both left and right ends of the shelf 300 are connected with vertical plates 330 extending below the shelf 300. The left side plate 230 is connected to the left vertical plate 330 through a front-rear sliding mechanism 400, and the right side plate 240 is connected to the right vertical plate 330 through another front-rear sliding mechanism 400.
[0051] See also Figure 2 and Figure 3In some embodiments, the shelf also includes a rocker 600, which can be rotatably arranged under the shelf 300, and the front and rear ends of the rocker 600 are respectively provided with a clamping head 610 and a handle 620, the clamping head 610 and the handle 620 are parallel to each other and perpendicular to the rocker 600, and the front and rear ends of the bracket 200 are respectively provided with a front positioning notch 210 and a rear positioning notch 220, and the rocker 600 is driven to rotate and lift the clamping head 610 by the handle 620, and the clamping head 610 can be alternately lifted from the front positioning notch 210 and the rear positioning notch 220 to enable the shelf 300 to move on the bracket 200, and the clamping head 610 can be alternately clamped into the front positioning notch 210 and the rear positioning notch 220 to fix the position of the shelf 300 on the bracket 200.
[0052] Initially, the clamping head 610 is clamped into or inserted into the rear positioning notch 220, the shelf 300 is at the rear stop point position, and the shelf 300 is in a retracted state. At this time, the rear positioning notch 220 limits the forward and backward movement of the clamping head 610, thereby locking the rocker 600 and the shelf 300 on the bracket 200; then the handle 620 is driven, the rocker 600 rotates, and the rocker 600 drives the clamping head 610 to rotate, so that the clamping head 610 is lifted from the rear positioning notch 220, and the rear positioning notch 220 at this time will not be able to move the clamping head 610 0 forms a limit; then pull the shelf 300 forward, the shelf 300 and the rocker 600 move forward until the clamping head 610 is above the front positioning notch 210, release the handle 620, and under the action of gravity, the rocker 600 rotates in the opposite direction, and the clamping head 610 is clamped into the front positioning notch 210. The front positioning notch 210 limits the forward and backward movement of the clamping head 610, thereby locking the rocker 600 and the shelf 300 on the bracket 200. At this time, the shelf 300 is at the front stop point position, and the shelf 300 is in a forward extended state.
[0053] On the contrary, when the shelf 300 needs to be restored to the retracted state, the handle 620 and the rocker 600 are driven to rotate, the clamping head 610 is lifted from the front positioning notch 210, and the shelf 300 is pushed backward. The shelf 300 and the rocker 600 move backward until the clamping head 610 is above the rear positioning notch 220, the handle 620 is released, the rocker 600 rotates in the opposite direction, and the clamping head 610 will be re-engaged in the rear positioning notch 220.
[0054] The front positioning notch 210 and the rear positioning notch 220 are provided on the upper end surface of the bracket 200. During the process of pulling or pushing the shelf 300, the handle 620 is kept in the rotated position and the clamping head 610 will move above the bracket 200. If the handle 620 is not kept in the rotated position, the clamping head 610 will slide against the upper end surface of the bracket 200.
[0055] The shelf 300 is located above the bracket 200, and the shelf 300 shields the bracket 200 and the rocker 600, thereby improving safety and appearance. The rocker 600, the clamp 610, the handle 620, the front positioning notch 210 and the rear positioning notch 220 have high structural reliability.
[0056] It can be understood that the front positioning notch 210 and the rear positioning notch 220 are both arranged on the upper end surface of the bracket 200. The upper end surface of the bracket 200 is an inclined guide surface in the front and rear areas corresponding to the front positioning notch 210, which is conducive to the positioning of the clamping head 610 into the front positioning notch 210. The upper end surface of the bracket 200 is an inclined guide surface in the front and rear areas corresponding to the rear positioning notch 220, which is conducive to the positioning of the clamping head 610 into the rear positioning notch 220.
[0057] The clamp head 610 , the rocker 600 and the handle 620 are U-shaped.
[0058] In some of the embodiments, when there is one rocker arm 600, a front positioning notch 210 and a rear positioning notch 220 are respectively provided at the front and rear ends of the left plate 230 or the right plate 240; when there are two rocker arms 600, a front positioning notch 210 and a rear positioning notch 220 are respectively provided at the front and rear ends of the left plate 230, and a front positioning notch 210 and a rear positioning notch 220 are respectively provided at the front and rear ends of the right plate 240.
[0059] See also Figure 2 and Figure 3 In some embodiments, the lower surface of the shelf 300 is provided with a front support plate 310 and a rear support plate 320 along the front-to-back direction, and the front support plate 310 and the rear support plate 320 are provided with a limiting hole with an axial direction in the front-to-back direction, and the front end and the rear end of the rocker 600 are respectively penetrated through the limiting hole of the front support plate 310 and the limiting hole of the rear support plate 320. The front support plate 310 and the rear support plate 320 play the role of stably connecting the rocker 600 to the shelf 300, so that the rocker 600 can move forward and backward with the shelf 300, and can also rotate around its own axis.
[0060] The front support plate 310 and the rear support plate 320 have the same structure. The front support plate 310 includes a first horizontal portion, a vertical portion and a second horizontal portion which are connected in sequence.
