Description

Technical Field

[0001] This utility model relates to the field of folding table technology, and in particular to a table beam folding assembly. Background Technology

[0002] Currently available table beam folding structures have significant shortcomings in terms of fixing methods and structural design: Firstly, in terms of operation, their fixing relies heavily on traditional components such as bolts and clips, making the process cumbersome. Bolt connections require repeated tightening and loosening with tools, which is not only time-consuming but also extremely inconvenient in scenarios requiring frequent folding. While clip-on structures do not require tools, the step-by-step locking and unlocking operations make quick switching difficult. Secondly, in terms of structure, existing folding components often contain multiple independent parts, such as crossbars, reinforcements, and multi-stage hinge shafts, resulting in a complex overall mechanism. This not only increases the difficulty of production and assembly, hindering mass production, but also causes inconvenience for later maintenance due to the complex interrelationships between parts. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a table beam folding assembly that is not only easy and efficient to operate, but also has the advantages of simple structure and low cost.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A table beam folding assembly includes a first table beam, a second table beam coaxially arranged with the first table beam, and a fixing plate disposed between the first table beam and the second table beam. The two ends of the fixing plate are respectively hinged to the adjacent areas of the opposite ends of the first table beam and the second table beam. The opposite ends of the first table beam and the second table beam are each provided with fixing pins extending downward and passing through the fixing plate. The bottom end of the fixing plate is slidably connected to a sliding plate for simultaneously fixing the two fixing pins to the fixing plate or unlocking it.

[0006] Furthermore, the fixing pin is inverted T-shaped, including a cylindrical part and a pin post part connected to and located above the cylindrical part. The sliding plate is located between the upper surface of the cylindrical part and the lower surface of the fixing plate. The sliding plate has two slots on the side facing the two fixing pins. The two slots are respectively inserted into or disengaged from the corresponding pin post parts to fix or unlock the fixing pins.

[0007] Furthermore, it also includes two connectors, which are respectively inserted into the opposite ends of the first table beam and the second table beam, and the fixing pin is located at the bottom of the corresponding connector.

[0008] Furthermore, the fixing plate is provided with through holes at its upper and lower ends, so that when the first table beam and the second table beam are unfolded or folded, their respective fixing pins can be screwed into or out of the through holes.

[0009] Furthermore, the bottom end of the fixed plate is provided with multiple sliding grooves extending radially along the table beam, and the upper surface of the sliding plate is provided with sliding rails extending radially along the table beam. The number of sliding rails is the same as the number of sliding grooves, and the multiple sliding grooves are slidably connected to the corresponding sliding rails.

[0010] Furthermore, it also includes two inverted T-shaped connecting pins, each connecting pin including a pin cap and a connecting portion connected to and located above the pin cap; the slide plate is provided with two clearance grooves extending radially along the table beam, the upper ends of the two connecting pins respectively pass through the corresponding clearance grooves and the fixing plate and are connected to the fixing plate, the slide plate slides to avoid the connecting portion through the clearance grooves when sliding, and the slide plate is sandwiched between the upper surface of the pin cap and the lower surface of the fixing plate.

[0011] Furthermore, both the first and second table beams have a first insertion cavity, a second insertion cavity, and a lower cavity that extend through their own axial direction. The lower cavity is located below the first and second insertion cavities and communicates with the first insertion cavity. Both connectors have a first insertion part and a second insertion part. The first insertion part and the second insertion part on each connector are respectively inserted into the first and second insertion cavities on the corresponding table beam.

[0012] Furthermore, the lower cavities of the first and second table beams each have downward-facing notches at their adjacent ends, and the two notches together form a cavity for accommodating and installing the fixing plate.

[0013] Furthermore, the fixing pin is located at the bottom of the first insertion part, and the fixing pins on the two insertion parts pass through the communication area between the lower cavity of the corresponding table beam and the first insertion cavity.

[0014] Furthermore, a pull plate extends downward from the end of the slide away from the fixing pin, the pull plate being used to drive the slide to slide along the groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, it is convenient and efficient to operate: the two fixing pins can be fixed or unlocked simultaneously by sliding the skateboard. No tools are needed.

The first table beam 1 and the second table beam 2 are both profile parts. The two ends of the fixing plate 3 are respectively hinged to the adjacent areas of the opposite ends of the first table beam 1 and the second table beam 2. The opposite ends of the first table beam 1 and the second table beam 2 are provided with fixing pins 41 extending downward and passing through the fixing plate 3. The bottom end of the fixing plate 3 is slidably connected to a sliding plate 5 for simultaneously fixing the two fixing pins 41 to the fixing plate 3 or unlocking them.

[0025] As described above, the fixing pin 41 is inverted T-shaped, including a cylindrical part 411 and a pin part 412 connected to and located above the cylindrical part 411. The sliding plate 5 is located between the upper surface of the cylindrical part 411 and the lower surface of the fixing plate 3. The sliding plate 5 has two slots 51 on the side facing the two fixing pins 41. The two slots 51 are respectively inserted into or disengaged from the corresponding pin part 412 to fix or unlock the fixing pin 41.

[0026] As described above, it also includes two connectors 4, which are respectively inserted into the opposite ends of the first table beam 1 and the second table beam 2, and the fixing pins 41 are provided at the bottom of the corresponding connectors 4.

[0027] As described above, the fixing plate 3 is provided with through holes 31 extending through its upper and lower ends, so that when the first table beam 1 and the second table beam 2 are unfolded or folded, the respective fixing pins 41 can be screwed into or out of the through holes 31.

[0028] As described above, the bottom end of the fixed plate 3 is provided with a plurality of sliding grooves 32 extending radially along the table beam, and the upper surface of the sliding plate 5 is provided with a sliding rail 52 extending radially along the table beam. The number of sliding rails 52 is the same as the number of sliding grooves 32, and the plurality of sliding grooves 32 are slidably connected to the corresponding sliding rails 52 respectively.

[0029] As described above, it also includes two inverted T-shaped connecting pins 33. Each connecting pin 33 includes a pin cap 331 and a connecting portion 332 connected to and located above the pin cap 331. The slide plate 5 is provided with two clearance grooves 53 extending radially along the table beam. The upper ends of the two connecting pins 33 pass through the corresponding clearance grooves 53 and the fixing plate 3 respectively and are connected to the fixing plate 3. When the slide plate 5 slides, it avoids the connecting portion 332 through the clearance grooves 53. The slide plate 5 is sandwiched between the upper surface of the pin cap 331 and the lower surface of the fixing plate 3.

[0030] As described above, the first table beam 1 and the second table beam 2 each have a first insertion cavity 11, 21, a second insertion cavity 12, 22 and a lower cavity 13, 23 that extend through their own axial direction. The lower cavities 13, 23 are located below the first insertion cavity 11, 21 and the second insertion cavity 12, 22 and communicate with the first insertion cavity 11, 21. Both plug-in parts 4 have a first insertion part 42 and a second insertion part 43. The first insertion part 42 and the second insertion part 43 on each plug-in part 4 are respectively inserted into the first insertion cavity 11, 21 and the second insertion cavity 12, 22 on the corresponding table beam.

[0031] As described above, the lower cavities 13 and 23 of the first table beam 1 and the second table beam 2 are provided with downward-facing notches 14 and 24 at their respective adjacent ends. The two notches 14 and 24 together form a cavity for accommodating and installing the fixing plate 3, so that the fixing plate 3 can be hidden inside the table beam, which not only saves space, but also makes the overall structure of the component more compact and beautiful.

[0032] As described above, the fixing pin 41 is located at the bottom of the first insertion part 42, and the fixing pins 41 on the two insertion parts 4 pass through the communication areas between the corresponding table beam lower cavity 13, 23 and the first insertion cavity 11, 21.

[0033] As described above, a pull plate 54 extends downward from the end of the skateboard 5 away from the fixing pin 41. The pull plate 54 is used to drive the skateboard 5 to slide along the slide groove 32, providing the user with a convenient point of force application, making it easier for the user to drive the skateboard 5 to slide along the slide groove 32, making the fixing and unlocking operation of the fixing pin 41 more effortless and convenient, and improving the user experience.

[0034] The steps for unfolding or folding the table beam assembly are as follows:

[0035] When unfolding: Rotate the first table beam 1 and the second table beam 2 so that they rotate around their respective hinge points until they are aligned. During the rotation, the fixing pins 41 on the two plugs 4 are screwed into the through holes 31 in the fixing plate 3 and protrude from the through holes 31. Then, pull the slide plate 5 to slide towards the fixing pins 41 until the two slots 51 on the slide plate 5 are respectively inserted into the pin portion 412 of the fixing pins 41, thus completing the unfolding and locking.

[0036] When folding: Pull the slide plate 5 away from the fixing pin 41 to disengage the slot 51 from the corresponding pin 412, then rotate the two table beams in the opposite direction to fold them around their respective hinge points to complete the folding.

[0037] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
