Description

Technical Field

[0001] The invention belongs to the technical field of workbenches, and in particular relates to a spliced ​​combined workbench. Background Art

[0002] With the development of science and technology, workbenches are widely used in mechanical processing, teaching and production, and their main function is to provide users with an operating platform. The workbench is suitable for various applications such as molds, fitters, testing, maintenance, and assembly. It usually has good corrosion resistance and dirt resistance while ensuring impact resistance and strong load-bearing capacity. The desktop needs to be specially treated and has the characteristics of corrosion resistance and strong impact resistance. A variety of desktop options can be selected to meet different usage requirements; the configured drawers and cabinet doors are convenient for users to store tools; power holes are reserved on the corners of the table for convenient installation of power sockets. The workbench is divided into light, medium and heavy workbenches and special workbenches. Various wall cabinets, single cabinets, double cabinets, etc. can be flexibly configured according to needs. Hanging boards, electrical panels, light top boards, adjustable foot cups, wheels, shelves and other desktop components can be installed. There are many options to meet the needs of various workstations. When used in the field of parts processing, in order to improve production efficiency, people often use workbenches for assembly line. At this time, the length of the workbench is often insufficient, and additional workbenches need to be spliced. However, conventional workbenches are not easy to be combined into a whole, and the structural strength of the joints is insufficient, which affects the actual processing and use. In addition, the workbench is large in size, occupies a large space, and is inconvenient to store and transport.

[0003] In order to solve the deficiencies in the prior art, people have conducted long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a car wash workbench composed of multiple car wash stations [201621434702.1], which includes at least two car wash stations that are detachably spliced ​​together; it also includes a connecting rod, which plays a role in splicing and positioning two adjacent car wash stations; one end of the connecting rod is a fixed end, which is fixed at the bottom of the first car wash station; the other end is a connecting end, which is arranged toward and extends into the bottom of the adjacent second car wash station, and the connecting end has a plug-in joint, the thickness of which is greater than the gap between the top step and the table when the second car wash station is opened, and is smaller than the gap between the top step and the table when the ladder column is perpendicular to the table during the folding process of the second car wash station. The present invention can extend the connecting end of the connecting rod under the second car wash station when the second car wash station is not fully opened, and after it is fully opened, the connecting end of the connecting rod is buckled and positioned by its top step and the table to complete the connection of the two car wash stations.

[0004] The above solution solves the problem of inconvenient storage of the workbench to a certain extent, but the solution still has many shortcomings, such as insufficient structural strength of the joints during splicing. Summary of the invention

[0005] The object of the present invention is to provide a spliced ​​combined workbench with reasonable design and stable structure at the splicing parts in view of the above problems.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: the splicing and modular workbench comprises a workbench main body, both ends of the workbench main body are connected with support leg assemblies through a rotating mechanism, an unfolding and fixing structure is respectively installed between the two sides of the workbench main body and the rotating mechanism, a folding and fixing structure is installed between one side of the workbench main body and the rotating mechanism, a splicing assembly is installed below one end of the workbench main body, the workbench main body comprises a main workbench and auxiliary workbenches are installed on both sides of the main workbench through a clamping mechanism, both ends of the workbench main body are closed by joint heads composed of elastic materials, the splicing assembly comprises a lap plate installed at one end below the workbench main body, and axially extending sliding grooves are opened on the auxiliary bosses on both sides of the lap plate. A limit block is installed at the lower end of the auxiliary workbench through a fixing bolt and the limit block is inserted into the sliding groove. A limit sheet is distributed at the lower edge of the limit block and the upper end of the limit sheet is fitted with the lower end of the lap plate. A positioning mechanism is installed between the main workbench and the lap plate. The positioning mechanism includes a positioning groove extending along the central axis of the lap plate.

A plurality of limit plates folded downward are arranged at the outward end of the lap plate. A sheath is sleeved on the limit plate. Limit edges folded downward are arranged on both sides of the lap plate. A notch is opened on the limit edge to engage with the rotating mechanism. A notch opposite to the rotating mechanism is opened on the main boss in the middle of the lap plate. An additional splicing component is added at the lower end of the workbench body to improve the structural strength of the joint when multiple workbenches are spliced, so that they are not easily misplaced or separated after splicing.

Adding a rotating mechanism between the workbench body and the support leg assembly avoids direct connection between the support leg assembly and the workbench body, improves the rotation stability, and the support leg assembly is folded with the workbench body for easy storage and transportation.

[0008] In the above-mentioned spliced ​​combined workbench, a support block is installed on one side of the rotating triangle plate close to the limiting edge of the lap plate, and the support block surrounds the rotating tube, and the outer arc surface of the support block is pressed and fitted with the lower end of the workbench body. The support block evenly disperses the force borne by the workbench body to avoid structural collapse caused by excessive force in one place.

[0009] In the above-mentioned spliced ​​combined workbench, the support leg assembly includes a ladder column that is fitted with a rotating triangle plate, its mounting plate and a mounting limit plate, the long side of the ladder column is bent inward to form a reinforcement angle, a ladder plate fixing sleeve is installed in the middle of the ladder column, ladder plates are connected between the ladder columns and the ladder plates are inserted into the ladder plate fixing sleeve, support strips are connected between the two sides of the ladder plates and the ladder columns, an anti-skid sleeve is sleeved at the lower end of the ladder column and a plurality of anti-skid grooves are distributed at the bottom of the anti-skid sleeve, and a plurality of through holes and convex hole platforms are opened at the upper end of the ladder plate.
