Description

Steel cabinet plate assembly structure and assembly method

Technical Field

The invention relates to a steel cabinet plate assembly structure and an assembly method, and belongs to the technical field of steel cabinets.

Background

The manufacture of cabinets by stainless steel plates in the field of cabinets has become popular gradually, and the stainless steel plates have the characteristics of safety, sanitation, environment friendliness, attractive appearance, cleanness, fashion, no color change and the like. The stainless steel cabinet can be separated and combined, and all the components can be freely installed and combined, so that the stainless steel cabinet has complete functions. Stainless steel table top the stainless steel table top surface is very front guard, and the brilliant crystal is not easy to be dirty. Even if being stained with greasy dirt, the utility model is easy to clean and can be used for a plurality of days to be bright as new. Xia Tianshi is cool to touch, and can eliminate the feeling of heat smoke and dysphoria during cooking.

In the conventional structure in which a plate material such as a top plate, a bottom plate, a back plate, etc. is attached to a plate material such as another side plate in a box, it is necessary to attach pins to the joint of the plate materials and apply an adhesive. And the change of the adhesive amount and the change of the size of the plate can lead to the change of the strength of the supporting box body. In addition, vibration due to opening and closing of doors attached to furniture, cabinets, and the like. Or the joints may loosen due to excessive cabinet loading, etc.

In some cases, the reinforcement is installed between the plates to prevent the joint from loosening, but the reinforcement exposed to the outside is conspicuous, and has a disadvantage of being unsightly.

In addition, the plates forming the back plate and the side plates must be connected by screws, and the screw connection requires a long time to assemble, and the assembly is troublesome, so that the cabinet cannot be assembled at low manpower and material costs.

In addition, when assembling the cabinet, a certain curing time is required until the bonding is completed using an adhesive. For this reason, the adhesive curing requires more time, and it is impossible to assemble the cabinet at low cost. For these reasons, an adhesive is used in joining the plates.

Based on the above, a novel steel cabinet is designed in the prior art, according to the invention patent with the Chinese patent publication number of CN102240109A, a seamless welding-free stainless steel cabinet body assembly structure is provided, which is composed of a left side plate, a right side plate, a top plate, a bottom plate and three-in-one fittings, wherein the left side plate, the right side plate, the top plate, the bottom plate and the three-in-one structures are assembled into an integral stainless steel cabinet body, three-in-one connecting screws are arranged at the openings of the left side plate and the right side plate, three-in-one connecting screws are arranged at the openings of the top plate, the bottom plate and the nearest left side plate, three-in-one eccentric wheels are arranged at the openings of the top plate, the bottom plate and the nearest left side plate, and the eccentric wheels on the top plate are screwed.

However, the cabinet assembly structure does not need adhesives or welding, the joints are not obvious, the beauty is not affected, and the following defects still exist:

as shown in fig. 1, the first panel 200 and the second panel 206 are assembled together by the same structure as the plate assembly according to the above invention, the first panel 200 is provided with a first joint hole 201 facing inwards on the side surface thereof, the second panel 206 is provided with a second joint hole 202 at a position corresponding to the first joint hole 201, the second panel 206 is provided with a limit branch hole 205 above the inner side of the second joint hole 202, the first joint hole 201 and the second joint hole 202 are connected by a connecting member 203, the left end of the connecting member 203 is provided with a screw thread, the right end is provided with a clamping portion, the left end screw thread is in screw connection with the first joint hole 202 on the first panel 200, the right end clamping portion is inserted into the second joint hole 202, the clamping portion faces the limit branch hole 205, and then the locking member 204 is inserted into the limit branch hole 205 from the outside to limit the clamping portion of the connecting member 203, thereby realizing seamless welding-free assembly between cabinet plates.

As shown in fig. 1, the connecting structure with the limiting branch hole 205 and the locking member 204 has a gap, that is, the limiting branch hole 205 is still exposed to the outside of the plate material, but the aesthetic appearance is still affected although not obvious, on the one hand, the locking member 204 has a high cost, and the process of inserting the locking member 204 increases the burden of an operator.
