Description

[Technical field]

[0001] The invention relates to a clamping structure on a table support frame, in particular to a multi-directional V-shaped clamping structure used on the table support frame. [Background technology]

[0002] At present, there are innumerable support frame structures for support tables, but there are three main connection methods of support frames commonly used in the market: the first is an inner-outer sleeve connection method, in which an inner tube is connected to the support foot, a detachable crossbeam is put on the inner tube and connected with fasteners; the second is a straight-line piece connection method, in which a fixed crossbeam is connected to the support foot, and a straight-line piece is fixedly connected to the detachable crossbeam, and the straight-line piece is connected to the fixed crossbeam with fasteners to form a support frame for the support table; the third is a U-shaped buckle clamping connection method, in which a fixed crossbeam is connected to the support foot, and the other end is connected to a U-shaped lower buckle, a U-shaped upper buckle is provided on the detachable crossbeam, and then the U-shaped upper buckle cooperates with the U-shaped lower buckle, and is fastened and connected by fasteners.

[0003] According to the connection methods used by the support frames used for support tables on the market, it can be seen that the commonly used connection methods currently have the following problems: First, the packaging volume of the support frame is large, and the goods are easily damaged during transportation, and the storage and transportation costs are high; second, the connection efficiency is low, and the stability of the table is poor; third, a connector can only be used on a table of a certain specific shape. If the support legs are replaced with other shapes, the connector needs to be molded separately, which wastes time and cost; fourth, the degree of mold production is low and the production cost is high; fifth, it is difficult to achieve connection between multi-material components, such as connecting wooden support legs to steel beams. [Summary of the invention]

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a multi-directional V-shaped clamping structure for a table support frame.

[0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-directional V-shaped clamping structure on a table support frame, including a bidirectional V-shaped clamping die-casting, wherein the bidirectional V-shaped clamping die-casting is respectively provided with a bidirectional outer V-shaped surface and a bidirectional inner V-shaped surface, a crossbeam is connected to the bidirectional outer V-shaped surface by fasteners, and a bidirectional V-shaped leg with a V-shaped surface is connected to the bidirectional inner V-shaped surface by fasteners, and the bidirectional V-shaped leg is tightly matched with the bidirectional inner V-shaped surface.

[0006] The multi-directional V-shaped clamping structure used on the table support frame also includes a multi-directional V-shaped clamping die-casting, which is composed of two unidirectional V-shaped clamping die-castings connected by a pin. The multi-directional V-shaped clamping die-casting is respectively provided with a multi-directional outer V-shaped surface and a multi-directional inner V-shaped surface. The crossbeam is connected to the multi-directional outer V-shaped surface by fasteners, and the multi-directional V-shaped legs with V-shaped surfaces are connected to the multi-directional inner V-shaped surface by fasteners. The multi-directional V-shaped legs are tightly matched with the multi-directional inner V-shaped surface.

[0007] Preferably, the top and bottom of the bidirectional outer V-shaped surface protrude laterally to form a bidirectional trapezoidal platform, a straight piece is provided inside the crossbeam, and a trapezoidal opening that closely matches the bidirectional trapezoidal platform is provided on the crossbeam.

[0008] Preferably, the top and bottom of the multi-directional outer V-shaped surface protrude laterally to form a multi-directional trapezoidal platform, and the multi-directional trapezoidal platform is tightly matched with the trapezoidal opening on the crossbeam.

[0009] Preferably, a notch is provided at one end of the one-way V-clamping die casting, and a tapered pin hole and a tapered pin are respectively provided on the notch.

[0010] The beneficial effects of the present invention are as follows: the bidirectional V-clamping die casting can be assembled with beams in two directions, the multidirectional V-clamping die casting can be assembled in three directions or even more directions, and the bidirectional V-clamping die casting and the multidirectional V-clamping die casting can be used on supporting feet of different shapes, which reduces mold opening time, improves production efficiency, reduces production costs, and has good stability, a small packaging area, reduces transportation costs, and greatly improves corporate benefits.

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, the present invention is used for a multi-directional V-shaped clamping structure on a table support frame, including a bidirectional V-shaped clamping die-casting 1, wherein the bidirectional V-shaped clamping die-casting 1 is respectively provided with a bidirectional outer V-shaped surface 11 and a bidirectional inner V-shaped surface 12, the top and bottom of the bidirectional outer V-shaped surface 11 protrude laterally to form a trapezoidal platform 13, a crossbeam 2 is connected to the bidirectional outer V-shaped surface 11 by fasteners, a straight piece 21 is provided inside the crossbeam 2, a trapezoidal mouth 22 that closely matches the bidirectional trapezoidal platform 13 is provided on the crossbeam 2, a bidirectional V-shaped leg 3 with a V-shaped surface is connected to the bidirectional inner V-shaped surface 12 by fasteners, and the bidirectional V-shaped leg 3 closely matches the bidirectional inner V-shaped surface 12.

[0021] like Figure 2 As shown, the multi-directional V-shaped clamping structure used on the platform support frame of the present invention also includes a multi-directional V-shaped clamping die-casting, which is composed of two unidirectional V-shaped clamping die-castings 44 connected by a pin, and the multi-directional V-shaped clamping die-casting is respectively provided with a multi-directional outer V-shaped surface 41 and a multi-directional inner V-shaped surface 42, and the top and bottom of the multi-directional outer V-shaped surface 41 protrude laterally to form a multi-directional trapezoidal platform 43, and the crossbeam 2 is connected to the multi-directional outer V-shaped surface 41 by fasteners, and the multi-directional trapezoidal platform 43 is tightly matched with the trapezoidal mouth 22 on the crossbeam 2, and the multi-directional inner V-shaped surface 42 is connected to the multi-directional V-shaped leg 5 with a V-shaped surface by fasteners, and the multi-directional V-shaped leg 5 is tightly matched with the multi-directional inner V-shaped surface 42.

[0022] like Figure 3 As shown, one end of the one-way V-clamping die casting 44 is provided with a notch, and a tapered pin hole 441 and a tapered pin 442 are respectively provided on the notch. Two one-way V-clamping die castings 44 are connected by a tapered pin to form a multi-directional V-clamping die casting. Such a setting makes them fit perfectly and reduces the defects caused by using fasteners for connection.

[0023] like Figure 4 As shown, in Figure 1The specific connection method of the bidirectional V-clamping die casting 1 in the embodiment of the present invention is as follows: the first step is to weld a word piece with a cross beam, and at the same time weld another word piece with another cross beam to complete the group welding assembly of the cross beam; the second step is to align the outer V-shaped surface of the bidirectional V-clamping die casting with the inner V-shaped surface of the cross beam, and use a fastening screw to screw into the threaded hole of the word piece to lock the cross beam and the bidirectional V-clamping die casting to complete the assembly of the bidirectional V-clamping die casting and the cross beam; the third step is to refer to the assembly method of the third step, and fasten the bidirectional V-clamping die casting and the cross beam with fastening screws to complete the assembly of the bidirectional V-clamping die casting and the cross beam; the fourth step is to screw the outer V-shaped surface of the bidirectional inner V-shaped surface of the bidirectional V-clamping die casting with the leg of the V-shaped surface into the threaded hole of the leg with the V-shaped surface, and lock it.

[0024] like Figure 5 As shown, in Figure 2 The specific connection method of the multi-directional V-clamping die casting in the embodiment is as follows: the first step is to weld the one-way V-shaped plate and the crossbeam together, there are three groups in total, and the first step of welding assembly is completed; the second step is to align the outer V-shaped surface of the one-way V-shaped clamping die casting with the inner V-shaped surface of the crossbeam, and use the fastening screws to screw into the threaded holes of the one-way V-shaped plate to lock the crossbeam and the one-way V-shaped clamping die casting to complete the assembly of the one-way V-shaped clamping die casting and the crossbeam; the third step is to fasten the one-way V-shaped clamping die casting and the other crossbeam with the fastening screws in the same way to complete the assembly of the one-way V-shaped clamping die casting and the crossbeam; the fourth step is to fasten the one-way V-shaped clamping die casting and the other crossbeam with the fastening screws. In the first step, two unidirectional V-clamping die castings are connected by plug-in card type to form a multi-directional V-clamping die casting; in the fifth step, the outer V-shaped surface of the multi-directional V-clamping die casting is aligned with the inner V-shaped surface of the crossbeam, and a fastening screw is screwed into the threaded hole of the one-piece piece to lock the crossbeam and the multi-directional V-clamping die casting to complete the assembly of the multi-directional V-clamping die casting and the crossbeam; in the eighth step, the inner V-shaped surface of the multi-directional V-clamping die casting is aligned with the outer V-shaped surface of the leg with the multi-directional V-shaped surface, and it is locked with a fastening screw to complete the assembly of the multi-directional V-clamping die casting and the leg with the V-shaped surface.

[0025] like Figure 6 As shown, the bidirectional V-clamping die-castings are respectively fastened to connect the supporting legs and the crossbeams, and the multidirectional V-clamping die-castings are respectively fastened to connect the supporting legs and the crossbeams, which are then combined and fastened to complete the support frame for the support table; in addition, the assembly composed of the bidirectional V-clamping die-castings may not be coordinated with the assembly composed of the multidirectional V-clamping die-castings, that is, four groups of assemblies composed of the bidirectional V-clamping die-castings cooperate with each other to complete the support frame for the support table.

[0026] The present invention provides a bidirectional V-clamping die casting and a multidirectional V-clamping die casting. The bidirectional V-clamping die casting can be connected to beams in two directions, and the multidirectional V-clamping die casting can be connected to beams in three directions. Such a configuration generates a rebound clamping force while being subjected to the tightening force of the screws. The screws are tightened more and more, which optimizes the stability of the assembly. Moreover, the legs of different shapes can be connected as long as V-shaped surfaces that match and connect with the legs of different shapes are provided. In addition, the bidirectional V-clamping die casting and the multidirectional V-clamping die casting can be universal parts. At the same time, the beam structure connected to the die casting is the same, and only the length of the beam needs to be calculated, which improves the production and assembly efficiency.

[0027] This invention can be used to connect components of various types of materials, has high connection efficiency and good stability, and can greatly improve production benefits.
