Abstract
A tongue and groove connection structure comprises a tongue and a groove which are provided on two components relatively. The utility model is characterized in that: the concave part of the groove is provided with a concave inner tongue for matching; the projection of the tongue is provided with a convex inner groove used for receiving the concave tongue; and the concave tongue can be an independent component. After the concave inner tongue and the convex inner groove, namely the double male-female tongues are adopted and the two components are assembled, the concave inner tongue has a wedge spreading effect. The pre-tightening force between the tongue and the groove is greatly increased through the wedge expanding force of concave inner tongue and the contraction force at two sides of the groove. The firmness is improved. For the connection of component with smaller thickness, a round log pin structure can be adopted and the vacuum suction force is used for reinforcing the engagement pre-tightening force between the components. The effect is more obvious if a plurality of round log pins are provided.
Description
[technical field]
The utility model is the draw bail of two members, especially belongs to a kind of slot mortise coupling structure.
[background technology]
Two members connect, and for example slot mortise coupling structure is adopted in the connection between two flat boards usually, processes tenon and groove respectively earlier on the parts that two need connect that is:, carries out assembly again and makes two parts be connected into integral body.For guaranteeing the firm connection of two parts, also take further measures usually in the prior art: for bright tenon, then on the tenon after the assembling, increase pretightning force with wedge spreading technology; To dowel then is to meet the demands by round log pin and tenon groove structure.There are the following problems for this traditional reinforcement process: not attractive in appearance although wedge spreading technology can be used for bright tenon structure, some occasion for example then is difficult to adopt on modern furniture, the ornamental very strong products such as Men Ti; The structure of round log pin and tenon is when reality is used, and linking intensity is low, easily comes off.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of slot mortise coupling structure, adopt this draw bail after, pretightning force is strong between the rebate, is particluarly suitable for using on modern furniture, the ornamental very strong products such as Men Ti.
For achieving the above object, the utility model has adopted following technical scheme: this slot mortise coupling structure comprises and is oppositely arranged on two tenon and grooves on the member, it is characterized in that: the recess of described groove have one recessed in tenon, be complementary therewith, the protuberance of described tenon be provided with one be used to admit described recessed in the protruding inner groovy of tenon.
Aforesaid a kind of slot mortise coupling structure, it is characterized in that: described recessed interior tenon is an individual components, the recess of described groove also is provided with a secondary groove, tenon is embedded in closing in the chamber that described protruding inner groovy and this secondary groove form in recessed, and the both ends of the surface of recessed interior tenon and close and leave the space between the diapire of chamber respectively.
Aforesaid a kind of slot mortise coupling structure is characterized in that: described recessed interior tenon is a straight pin, and the diameter of straight pin directly is complementary with the chamber of closing the chamber.
Aforesaid a kind of slot mortise coupling structure is characterized in that: the shape of described protruding inner groovy and secondary groove, big or small consistent.
Beneficial effect: compared with prior art, after adopting recessed interior tenon, the promptly two tongue and groove structure technology schemes of protruding inner groovy, during two member assemblings, in fact described recessed interior tenon has played the effect of wedge spreading technology, tenon is embedded in the middle of the tenon in recessed, formed groove the tenon both sides, recessed in the situation of tenon in the middle of tenon, by the wedge tension of recessed interior tenon and the convergent force of groove both sides, strengthened the pretightning force between tenon and groove greatly, firmness is better.Connect for thin member, then adopt the distressed structure of two tongue and grooves, that is: tenon in recessed is developed into the round log latch structure, utilize syringe vacuum principle, the dependence pull of vacuum strengthens the interlock pretightning force between the coupling member, and, according to the thickness of coupling member, select the round log pin that quantity is set, guarantee firmness.
[description of drawings]
Fig. 1 is the broken section structural representation of an embodiment of the utility model.
Fig. 2 is the distressed structure partial schematic sectional view of Fig. 1.
Among the figure: member 1, member 2, upper convex tenon 11, lower convex tenon 12, recessed interior tenon 21, protruding inner groovy 3, round log pin 4, space 5.
[specific embodiment]
Referring to Fig. 1.The point of attachment of member 1 is a tenon, and this tenon is made of upper convex tenon 11 and lower convex tenon 12, and protruding inner groovy 3 is offered at upper convex tenon 11 and lower convex tenon 12 middle parts.The point of attachment of the point of attachment of member 2 and member 1 is complementary, and recessed interior tenon 21 is arranged on the middle part of whole groove.Certainly, the shape of tenon, groove, and protruding inner groovy 3, recessed in the shape of tenon 21, can be out of shape as required, as long as coupling mutually.
Referring to Fig. 2.Consider the thinner thickness of member 1, member 2, should not adopt structure shown in Figure 1, therefore, adopt following distressed structure.Its distortion is: 1, tenon 21 in recessed among Fig. 1 is developed into an individual components pin, pin with round log pin 4 for well; 2, offer a secondary groove to member 2 depths again at bottom portion of groove, be used for round log pin 4, make round log pin 4 be embedded in closing in the chamber of protruding inner groovy 3 and the formation of secondary groove by close-fitting.What deserves to be explained is: the diameter of straight pin 4 should directly be complementary with the chamber of closing the chamber, and diameter helps increasing the wedge tension slightly greatly, and certainly, the diameter of straight pin 4 also can axially change, as long as can correspond respectively to protruding inner groovy 3 and secondary groove.For strengthening the interlock pretightning force, all reserve certain space 5 with the two ends, chamber of closing that round log pin 4 shapes are complementary, utilize syringe vacuum principle, the dependence pull of vacuum is come the interlock pretightning force between reinforcement, if according to the coupling member thickness, it will be more obvious that multiple tracks round log pin effect is set.
This slot mortise coupling structure is specially adapted to products such as modern furniture, Men Ti, especially the rail top of door body, middle-grade and following connecting of cap head and frame, connects firm, long service life.
