Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0030] Example 1

[0031] like Figures 1-13 As shown, an extendable tabletop support has the function of extending one aluminum tabletop support by itself and extending two aluminum tabletop supports by splicing them together. The two functions can be used simultaneously or separately. For convenient transportation, the aluminum tabletop support can be folded, and the two aluminum tabletop supports can be combined into one unit after being folded. The specific structure includes two main parts: the support tabletop 1 and the legs 2.

[0032] like Figure 1 As shown, the support tabletop 1 includes an independent original part and an extended part. The original part includes a left tabletop 3 and a right tabletop 4, and the extended part is a spare tabletop 5. Each tabletop is made of formed aluminum profile.

[0033] like Figures 2-4 As shown, both the left platform 3 and the right platform 4 include: a profile 11, an inner connector 12 fixedly connected to one inner end of the profile 11, and an outer connector 13 fixedly connected to one outer end of the profile 11.

[0034] For the convenience of mutual connection between the tables, the outer end surface of the inner connecting piece 12 is provided with two protruding first pin columns 31 and second pin columns 33 and two recessed first pin grooves 32 and second pin grooves 34 for guiding effect, ensuring that the position is not dislocated when docking, the first pin column 31 and the first pin groove 32 are horizontally arranged and close to the table, and the second pin column 33 and the second pin groove 34 are horizontally arranged and relatively far away from the table; wherein the first pin column 31 and the first pin groove 32 are hollow and internally provided with elastic hanging buckles 35, the bottom of the elastic hanging buckle 35 is fixed, which acts as a fulcrum, the middle of the elastic hanging buckle 35 is an opening pressing handle part, and the first pin column 31 and the first pin groove 32 are provided with a clamping part 35K for connecting the hook of the elastic hanging buckle 35; the connecting surface of the outer connecting piece 13 is provided with protruding third pin columns 41 and fourth pin columns 43 and two recessed third pin grooves 42 and fourth pin grooves 44 for guiding effect, ensuring that the position is not dislocated when the aluminum table supports are connected with each other; the positions of the elastic hanging buckles 35 arranged in the left table 3 and the right table 4 need to be staggered with each other, that is, when the left table 3 and the right table 4 are connected, the corresponding pin columns enter the pin grooves, and the elastic hanging buckles 35 also enter the opposite and corresponding clamping part 35K to complete clamping;

[0035] The left table 3 is provided with a type-matched lock hook 47 and a lock column 48 below the outer connecting piece 13, and a long lock buckle 46 is further arranged on the outer end surface thereof; the right table 4 is also provided with a type-matched lock hook 47 and a lock column 48 below the outer connecting piece 13, and a short lock buckle 45 is arranged on the upper surface thereof; the upper surface of the outer connecting piece 13 in the left table 3 is further provided with a first lock hook connecting part 45b for connecting the lock hook of the short lock buckle 45; the end surface of the outer connecting piece 13 in the right table 4 is provided with a second lock hook connecting part 46b for connecting the lock hook of the long lock buckle 46; when the two aluminum table supports are connected with each other, Figure 11 As shown, the lock hook 47 and the lock column 48 on one aluminum table support are respectively buckled and connected with the lock hook 47 and the lock column 48 on the other aluminum table support, and then the short lock buckle 45 on one aluminum table support is buckled and connected with the first lock hook connecting part 45b on the other aluminum table support, so that the buckling connection at the upper and lower positions and the pin column and pin groove insertion at the end surface can form a joint without dislocation and with sufficient connection strength.

[0036] When the two aluminum table supports are connected with each other in a back-to-back manner, the hooks of the long lock buckles 46 at the two ends of the upper and lower aluminum table supports are respectively buckled and connected with the second lock hook connecting part on the other aluminum table support, so that the two aluminum table supports can be quickly connected into one.

[0037] Since the inner connecting pieces 12 on the left table top 3 and the inner connecting pieces 12 on the right table top 4 are oppositely arranged, when the left table top 3 and the right table top 4 are connected, the pin posts and the pin slots on the left table top 3 are matched with the pin posts and the pin slots on the right table top 4, that is, they are insertedly matched with each other, that is, the left table top 3 and the right table top 4 are butted against each other to form the original part of the support table top 1 through the inner connecting pieces 12. When butted, the elastic hanging buckles 35 are insertedly inserted into the hollow holes of the opposite first pin posts 31 and the first pin slots 32 in an up-down staggered manner, are pushed away by the outer side walls of the hollow holes to be deformed and inserted, are reset after being in place, are buckled to the bottom of the hollow hole, and play a buckling and locking role. When disconnected, only the handle part in the middle of the elastic hanging buckle 35 needs to be pushed inward, so that the head hook is separated from the bottom of the hollow hole, and the elastic hanging buckle 35 can be pulled out.

[0038] As shown in Figures 5-6 , the foot stool 2 comprises a middle long rod 21, two connecting seats 22 arranged at both ends of the long rod 21 respectively, the material of the long rod 21 is a rectangular steel pipe, and T-shaped sliding rails 28 are symmetrically arranged on both sides of the connecting seat 22. The T-shaped sliding rails 28 are used for slidingly matching with the bottom of the support table top 1. In use, the left table top 3 and the right table top 4 are respectively slidably connected with the corresponding T-shaped sliding rails 28 on one side. After connection, when the left table top 3 and the right table top 4 slide to the center, the two table tops are in contact and connected, and the outer side of each of the two table tops is in contact with the outer side of the long rod 21 at the same time. Therefore, the positions of the two table tops after connection are fixed and reliable.

[0039] The middle table top 5 comprises a middle profile 51 suspended on the long rod 21, two middle connecting pieces 52 fixedly connected at both ends of the middle profile 51, and a turnover sleeve 58 arranged at the middle part of the middle profile 51. Figures 10-11 As shown in , the turnover sleeve 58 is rotatably sleeved on the long rod 21 and has an opening on the side facing the middle profile 51. The size of the opening is just enough to allow the long rod 21 to pass through. The position of the middle profile 51 relative to the opening is provided with a through-length matching groove matching the width of the long rod 21. When the middle table top 5 is turned over, the table top of the middle profile 51 is horizontal, the through-length matching groove falls into the long rod 21 and is supported by the long rod 21, and then the middle table top 5 can be connected with the left and right table tops. In order to facilitate connection, the outer end faces of the two middle connecting pieces 52 are also provided with pin posts and pin slots of the same model as the pin posts and pin slots on the corresponding inner connecting pieces 12, which are used for guiding and ensuring that the positions are not staggered during butt joint. The bottom surface of the middle connecting piece 52 is provided with a support pad 57. When the middle table top 5 is in a suspended state, the support pad 57 is in contact with the corresponding left and right table tops on both sides, so that the table top 5 does not shake. The lower side of the middle part of the long rod 21 is provided with a semicircular positioning piece 29 for transversely limiting the turnover sleeve 58 and determining the height after the turnover sleeve 58 is turned over and falls into position. The determination of the height also supports the lengthened middle table top 5.

[0040] The two sides of the profile used by each table are symmetrically embedded with straight racks for use with the matching auxiliary equipment. Two T-shaped sliding grooves 15 are symmetrically arranged on both sides of the lengthwise fitting groove for assembly with the T-shaped sliding rail 28 on the connecting seat 22.

[0041] For easy moving, the foot frame 2 is equipped with handles 6 at both ends. The base part of the handle 6 is provided with a shaft sleeve hole 61 in the transverse direction. The shaft sleeve hole of one end of the handle 6 is fitted with a transverse wheel shaft 62, and the both ends of the wheel shaft 62 are respectively equipped with trolley wheels 63.

[0042] Transformation between each state and use:

[0043] Referring to all the drawings, the original part of the support table 1 composed of the left table 3 and the right table 4 is movably assembled on the foot frame 2 by combining the T-shaped sliding groove 15 on the bottom surface of the aluminum profile with the T-shaped sliding rail 28 on the connecting seat 22. The lengthened part of the support table 1 is composed of the middle table 5.

[0044] When the aluminum table support is lengthened, only the lock hooks of the elastic hanging buckles 35 of the inner connecting pieces 12 at the middle part of the original part of the support table 1 are loosened, the locking is released, the left and right tables are moved to both sides to make room for the middle table 5, the middle table 5 is turned over 180° around the long rod 21 and the long rod 21 is embedded into the lengthwise fitting groove of the middle table 5, the height is controlled by the semicircular positioning piece 29, so that the middle table is flush with the left and right tables, and then the moved left and right tables are pushed towards the middle table 5, so that the inner connecting piece 12 of the left table 2 is butted with the middle connecting piece 52 of the middle table 5, and the inner connecting piece 12 of the right table 3 is butted with the middle connecting piece 52 of the middle table 5, until the lock hooks of the elastic hanging buckles 35 are hooked, that is, the lengthening function is completed.

[0045] When two aluminum table supports are connected to each other, only the outer connecting piece 13 of the left table 2 of one aluminum table support is butted with the outer connecting piece 13 of the right table 3 of the other aluminum table support, guided by the pin columns of each other and inserted into the pin slot and pushed into place, the bottom surface is hooked by the lock hook 47 at one end and the lock column 48 at the other end and locked, and the working surface is connected and locked by the short lock buckle 45.

[0046] When the aluminum table support needs to be folded, the legs are folded towards the middle part of the support table 1 (in the unlengthened state) and are folded into the side straight rack groove of the middle table 5 after folding into place, and are in close contact with the straight rack, so that the folding state can be maintained. At this time, the handle 6 at the non-wheel end is pulled, and the wheels can roll on the ground, facilitating the movement of the aluminum table support and reducing the labor intensity.

[0047] When the two aluminum table top supports need to be folded and combined, the folded two aluminum table top supports are aligned in length direction, different ends are placed in staggered manner, the working surfaces of the middle table tops 5 of the two aluminum table top supports are pasted flat to each other, the lock hooks of the long lock buckles 46 of the two aluminum table top supports are buckled to the lock post plates of the long lock buckles 46 of the other, and the two aluminum table top supports are locked and fastened tightly, and the folding and combination of the two aluminum table top supports is completed.
