Description

Technical Field

[0001] This utility model relates to the field of sideboard technology, and in particular to a steel home sideboard frame structure. Background Technology

[0002] A sideboard is used to store tableware, drinks, snacks, and other restaurant supplies. Some families place small appliances (such as microwave ovens, food processors, and soy milk makers) on the countertop, which can easily make the countertop cluttered, lead to a poor hygiene environment, and make it inconvenient to clean.

[0003] Currently, Chinese patent CN215456574U discloses a frame structure for a dining sideboard. This frame structure, within its storage space, uses corner groove connectors (with a first right angle and a second right angle) bolted together to connect a horizontally movable support frame, allowing for adjustments to the height of the corresponding storage compartments to accommodate different appliances. However, this structure has the following drawbacks: 1. In terms of use, the stability of the horizontal support frame relies solely on the friction generated by bolt tightening, resulting in limited load-bearing capacity. Insufficient bolt tightening force or loosening can lead to a risk of collapse. Furthermore, the bolts located on the inner side lack operating space, making operation difficult. 2. In terms of production, the uprights connected to the corner groove connectors require the design of C-shaped slots, increasing manufacturing difficulty.

[0004] Therefore, we designed a steel frame structure for a home dining sideboard. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a steel dining sideboard frame structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel dining sideboard frame structure includes an upper main frame, a lower main frame, and front and rear columns connecting the upper and lower main frames. It also includes a horizontal support frame. The side walls of the front and rear columns are provided with multiple corresponding snap-fit ​​grooves along the vertical direction. The front and rear ends of the horizontal support frame are fixed to the snap-fit ​​grooves of the front and rear columns by snap-fit, respectively, so as to realize the quick locking and height adjustment of the horizontal support frame.

[0008] Furthermore, the rear end of the horizontal support frame is provided with a fixed locking block, the locking part of which is embedded in the locking groove of the rear column.

[0009] Furthermore, the front end of the horizontal support frame is provided with a sliding locking block, the locking part of which is embedded in the locking groove of the front column.

[0010] Furthermore, the sliding block includes a linear slide rail, a sliding block, and a push-pull rod installed on the bottom front end of the horizontal support frame. The sliding block is slidably connected to the linear slide rail and is provided on the inner side of the push-pull rod. By pushing and pulling back and forth, the sliding block is driven to be inserted into or disengaged from the locking groove of the front column.

[0011] Furthermore, a compression spring is provided between the rear end of the linear slide rail and the sliding block, and the elastic force of the compression spring causes the locking part of the sliding block to automatically engage in the locking groove of the front column.

[0012] Furthermore, the snap-fit ​​portion is cylindrical.

[0013] Furthermore, both the front and rear columns have U-shaped cross-sections, and their corresponding horizontal support frame sidewalls are provided with multiple equally spaced snap-fit ​​grooves along the vertical direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A rigid snap-fit ​​structure is adopted to replace the traditional bolt locking and fixing. Specifically, the horizontal support frame is embedded into the snap-fit ​​groove of the front / rear column through fixed and sliding snap-fit ​​blocks to form a pressing contact, avoiding the risk of falling due to loose bolts.

[0016] 2. The adjustment of the horizontal support frame can be achieved simply by manually pulling the push-pull tab to release the sliding block, and then by pulling the horizontal support frame to release the adjustment fixed block. No tools are required throughout the process, and the operation space only requires contact from the front, which solves the technical problems of limited operating space and high operation difficulty.

[0017] 3. Both the front and rear columns are made of U-shaped steel, which can be directly stamped to form the snap-fit ​​groove. Furthermore, the front and rear columns only have two types of symmetrical structural parts, which can effectively improve production efficiency. Attached Figure Description

[0024] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0025] Example 1, in conjunction with Appendix Figure 1-3 A steel dining sideboard frame structure includes an upper main frame 1, a lower main frame 2, a front column 3, a rear column 4, and a horizontal support frame 5. The upper main frame 1 and the lower main frame 2 are vertically connected by the front column 3 and the rear column 4 to form an integral frame structure.

[0026] The number of front pillars 3 and rear pillars 4 is 2 to 6. In this embodiment, the number of front pillars 3 and rear pillars 4 is 4.

[0027] In other words, two adjacent front columns 3 and two adjacent rear columns 4 form a receiving cavity, and a horizontal support frame 5 is installed in the receiving cavity, so that the receiving cavity is divided into an upper chamber and a lower chamber.

[0028] As required, the upper main frame 1 and the lower main frame 2 are made of square tubes welded together.

[0029] Furthermore, both the front column 3 and the rear column 4 have U-shaped cross-sections, such as U-shaped steel. The side walls of the corresponding horizontal support frame 5 (hereinafter referred to as the "inner side wall," and the other side wall as the "outer side wall") are provided with multiple equally spaced locking slots along the vertical direction, and the locking slots of the front column 3 correspond one-to-one with those of the rear column 4. The front and rear ends of the horizontal support frame 5 are respectively locked into the corresponding locking slots of the front column 3 and the rear column 4. By selecting locking slots of different heights, the installation height of the horizontal support frame 5 can be flexibly adjusted to adapt to storage needs of different heights and dimensions.

[0030] This arrangement ensures that the front column 3 located to the left front of the horizontal support frame 5 and the rear column 4 located to the right rear of the horizontal support frame 5 have the same structure, as do the front column 3 located to the right front of the horizontal support frame 5 and the rear column 4 located to the left rear of the horizontal support frame 5. Furthermore, the front column 3 and the rear column 4 with different structures are also symmetrical components, making the workpiece more modular and facilitating production.

[0031] like Figure 4 As shown, a fixed locking block 6 is installed at the bottom of the horizontal support frame 5, corresponding to the locking groove of the rear column 4. The rear end of the fixed locking block 6 has a cylindrical locking part whose size matches the locking groove, allowing it to be embedded into the locking groove and ensuring a stable connection between the rear end of the horizontal support frame 5 and the rear column 4. If necessary, the locking groove is an inclined U-shaped hole.

[0032] like Figure 5 As shown, a sliding locking block 7 is provided at the bottom of the horizontal support frame 5 corresponding to the locking groove of the front column 3. The sliding locking block 7 includes a linear slide rail 71, a sliding locking block 72, and a push-pull rod 73. The linear slide rail 71 is fixed to the bottom surface of the horizontal support frame 5 by bolts. The sliding locking block 72 is slidably connected to the linear slide rail 71 and can move back and forth along the slide rail. The front end of the sliding locking block 72 has a cylindrical locking part, the shape of which matches the locking groove. A push-pull rod 73 is provided on the side near the middle of the receiving cavity for easy manual operation. That is, by pushing the push-pull rod 73 backward, the sliding locking block 72 moves backward, causing the locking part of the sliding locking block 72 to disengage from the locking groove of the column 3; by pulling the push-pull rod 73 forward, the sliding locking block 72 moves forward, causing the locking part of the sliding locking block 72 to embed into the locking groove of the column 3.

[0033] Furthermore, the sliding block 7 may also have a compression spring 74, which is installed between the rear end of the linear slide rail 71 and the block, providing elastic restoring force so that the sliding block 72 moves forward and its locking part automatically engages in the locking groove of the column 3 and always presses the locking groove.

[0034] Installation and Adjustment Steps

[0035] Fix the rear end: Align the fixed clip 6 at the rear end of the horizontal support frame 5 with the selected clip slot of the rear column 4 and insert it into the slot.

[0036] Adjusting the front end: Pull the push-pull rod 73 to move the sliding block 7 backward along the linear slide rail 71 and disengage it from the current locking slot of the front column 3; after raising or lowering the front end of the horizontal support frame 5 to the target height, release the push-pull rod 73, compress the spring 74 to push the block into the corresponding locking slot of the front column 3, and complete the height adjustment.
