Abstract

The utility model discloses a dovetail joint splicing structure of a school desk. The dovetail joint splicing structure comprises a component with a mortise structure and a component with a tenon structure, wherein the component with the mortise structure is provided with mortises, the component with the tenon structure is provided with tenons, and the mortises and the tenons are both of dovetail shapes. The component with the mortise structure is provided with multiple rows of mortises arranged in parallel, the component with the tenon structure is provided with multiple rows of tenons arranged in parallel, and the row number of the mortises and the tenons is the same. The dovetail joint splicing structure has the advantages that the defect of connection loosening because metal iron nails are prone to rust is overcome; the dovetail joint splicing structure is of ingenious combination between many wood pieces and few wood pieces, high wood pieces and low wood pieces, long wood pieces and short wood pieces, and therefore torsion of the wood pieces in all directions can be limited effectively; the assembly and splice process is simple and convenient, and the wood can not be split off; the surface of each face of the deck after assembly is smooth, and the danger that people are hurt by rough edges due to usage of the iron nails is avoided; and in addition, repair and disassembly such as replacing a leg of the desk are convenient and quick.

Description

A kind of dovetail joint splicing construction of school desk

Technical field

The utility model relates to a kind of splicing construction of school desk, particularly a kind of dovetail joint splicing construction of full solid wood desk.

Background technique

School desk is the necessity of school teaching, and its time that contacts with the student is also the longest, and the quality of desk workmanship also has influence on the quality of instruction of school and student's use safety.

Existing desk much all adopts the design of wooden table and irony table body, namely at irony table body wooden table is installed, and the basic screw that adopts connects between table body inside and table body and the table.The shortcoming that such desk shows is: damage easily, iron surface paint drops, and gets rusty; There are sharp burr at the splicing construction place, and student's safety is caused great impact; In addition, the table body of irony is out of shape easily, and the time one is long, often shows connection loosing, produces abnormal sound.

Also have, some school also uses the desk of solid wood, and namely table body and table all are that solid wood is made such solid wood desk, connecting method between its body inside and table body and the table is fixing for adopting nail to splice, and namely passes through directly to connect by iron nail between two solid wood parts; Perhaps as shown in Figure 1, connect in conjunction with iron nail 21 by irony L-type connecting sheet 22.The shortcoming that such desk shows is: the easy corrosion of metal iron nail or oxidation, connect looseningly thereby make, and cause desk to occur falling apart and affect working life; Iron nail connects can not limit wooden part effectively to the twisting of all directions, thereby even if the loosening phenomenon of desk also can appear in the iron nail non-corrosive after the use; Because solid wood is wooden hard, and iron nail is entered by crowded and the hard wedge of application to studies, and this process very easily causes the timber splitting, affects attractive in appearance and working life; Wood surface can cause surface irregularity after using iron nail, and its sharp burr also can abrade student's skin sometimes; In addition, in the maintenance of desk, unloading process, neither be very convenient.

The model utility content

The purpose of this utility model provides a kind of dovetail joint splicing construction of school desk, and the improvement by to connecting method between the solid wood of desk inside overcomes above-mentioned shortcoming of the prior art.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of dovetail joint splicing construction of school desk comprises band fourth of the twelve Earthly Branches structure member, band tenon structure parts, wherein is with fourth of the twelve Earthly Branches structure member to have fourth of the twelve Earthly Branches mouth, and band tenon structure parts have tenon, and fourth of the twelve Earthly Branches mouth and tenon all are dove-tail form.

During assembling, only the tenon with the tenon structure parts need to be inserted in the fourth of the twelve Earthly Branches mouth with fourth of the twelve Earthly Branches structure member and get final product.

Especially, such as the combination between the large plank of table homalographic, have the fourth of the twelve Earthly Branches mouth that many rows are arranged in parallel with fourth of the twelve Earthly Branches structure member, have the tenon that many rows are arranged in parallel with the tenon structure parts, the row of fourth of the twelve Earthly Branches mouth and tenon is identical.After installing like this, can make band fourth of the twelve Earthly Branches structure member and band tenon structure parts splice more firm stable.

The beneficial effect of the dovetail joint splicing construction of school desk described in the utility model is: the shortcoming that the connection of having avoided the metal iron nail to get rusty easily producing is loosening; Such dovetail joint structure be between the wooden part many with less, high and low, grow and lack between ingenious combination, can effectively limit wooden part to the twisting of all directions; The assembling splicing is simple and convenient, can not make the timber splitting; The surfacing of each face of desk after the assembling, the danger that the burr of having avoided the use iron nail to cause are hurted sb.'s feelings; In addition, also easily quick such as maintenance, dismounting as need changing a desk leg etc.

Embodiment

To shown in Figure 4, be the dovetail joint splicing construction of the utility model school desk, with fourth of the twelve Earthly Branches structure member cross-sectional configuration, with the schematic representation of tenon structure parts cross-sectional configuration such as Fig. 2.

A kind of dovetail joint splicing construction of school desk comprises band fourth of the twelve Earthly Branches structure member 11, band tenon structure parts 12, wherein is with fourth of the twelve Earthly Branches structure member 11 to have fourth of the twelve Earthly Branches mouth 31, and band tenon structure parts 12 have tenon 32, and fourth of the twelve Earthly Branches mouth 31 and tenon 32 all are dove-tail form.

During assembling, only the tenon 32 with tenon structure parts 12 need to be inserted in the fourth of the twelve Earthly Branches mouth 31 with fourth of the twelve Earthly Branches structure member 11 and get final product.

Especially, such as the combination between the large plank of table homalographic, have the fourth of the twelve Earthly Branches mouth 31 that many rows are arranged in parallel with fourth of the twelve Earthly Branches structure member 11, have the tenon 32 that many rows are arranged in parallel with tenon structure parts 12, fourth of the twelve Earthly Branches mouth 31 is identical with the row of tenon 32.After installing like this, can make band fourth of the twelve Earthly Branches structure member 11 and band tenon structure parts 12 splice more firm stable.
