[0002] The mortise and tenon is a combination of concave and convex connections between two wooden components. There is also a mortise and tenon combination method in educational building block toys, which mainly uses the tenon and the mortise groove to achieve the bite of the tenon and the mortise, thereby playing a connecting role.

[0003] According to the publication (announcement) number: CN114570038A, the publication (announcement) date: 2022-06-03, a modular mortise and tenon assembly building block and an assembly building block structure are disclosed. The modular mortise and tenon assembly building block includes a variety of basic components and rotary lock components. The basic components are provided with splicing slots. When the rotary lock components are assembled with the selected basic components, the assembled building blocks can be locked by rotating the rotary lock components.

[0006] In the prior art including the above-mentioned patent, during the construction of wooden building blocks, the convex surface of the tenon needs to be abutted against the concave surface of the mortise. During the operation, because the concave surface on the mortise is relatively large, in order to meet the space required for placing the tenon, one or more other mortise must also be placed. After the tenon is placed, due to the lack of support and limit, one hand needs to hold the mortise and the tenon tightly, and then use the other hand to take another or more mortise to assemble. Therefore, it cannot be directly snapped together and built like Lego without hand support. Therefore, in the process of building mortise and tenon building blocks, it is often inconvenient to operate with both hands, and it is impossible to provide sufficient time for educational thinking, which reduces the fun of playing with mortise and tenon building blocks.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-9As shown, a mortise and tenon combination building block toy comprises a tenon 1 and a mortise 11, and also comprises a plurality of triangular pieces 2 which are snap-fitted and assembled on the tenon 1, a main airway 31 is opened on the triangular piece 2, and eardrums 321 are respectively connected and arranged on both sides of the main airway 31;

[0040] The eardrum 321 is provided with a plurality of thorn rods 322 for assembling barbs 323, and the mortise 11 is provided with a plurality of rod holes 331 for assembling puncture holes 332, wherein:

[0041] The eardrum 321 on one side abuts against the mortise 11 , so that the eardrum 321 on the other side expands to drive the piercing rod 322 to be inserted into the rod hole 331 , and the barb 323 is engaged with the piercing hole 332 .

[0042] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the four corners of the tenon 1 are provided with a notch 20 with an inclined surface, and the inclined surface of the triangle piece 2 is abutted against the inclined surface on the notch 20, and the two bottom corners of the isosceles triangle triangle piece 2 are fixedly installed with a guard plate 21, and the triangle piece 2, the guard plate 21 and the components thereon are all stainless steel metal blocks.

[0043] Furthermore, a clamping column 22 is fixedly installed at the end of one of the two guard plates 21, and the end of the other guard plate 21 is bent to form an embedded cover 23, and a through hole 231 is opened on the embedded cover 23, and the clamping column 22 passes through the through hole 231, and a clamping hole 221 is opened on the end surface of the tenon 1, and the arc top of the clamping column 22 is clamped in the clamping hole 221, and the two guard plates 21 on the four triangular pieces 2 are clamped and assembled with each other end to end, and clamped on the tenon 1, so that the four triangular pieces 2 are interlocked, so that the tenon 1 can be engaged with the mortise 11 from any end face. During assembly, the triangular piece 2 can cooperate with the mortise 11; at the same time, a damping pad 232, specifically a rubber pad, is fixedly installed at the end of the through hole 231, and the clamping column 22 maintains contact with the damping pad 232 when it is clamped in the clamping hole 221, so that the clamping column 22 after clamping assembly has a greater friction force, which reduces the situation where the triangular piece 2 is separated from the tenon 1, and the triangular piece 2 also provides protection for the end face of the tenon 1, reduces the wear of the wooden tenon 1 caused by long-term contact friction, and reduces the shaking of the tenon 1 and the mortise 11 during installation.

[0044] Furthermore, the notch on the mortise 11 forms two main surfaces 301 and one secondary surface 302 , and the tenon 1 is assembled with a main surface 301 and a secondary surface 302 , and the rod hole 331 and the puncture hole 332 are arranged on the main surface 301 and the secondary surface 302 .

[0045] Furthermore, the eardrum 321 is specifically a rubber membrane, and the plurality of barbs 322 are symmetrically arranged according to the arc top of the eardrum 321, that is, the barbs 323 on the symmetrically arranged barbs 322 face the center line of the arc top of the eardrum 321, the barbs 332 and the barbs 323 are both stainless steel metal rods, and the barbs 323 are curved so that the barbs 323 are easy to deform. When the eardrum 321 abuts against the main surface 301, the symmetrically arranged barbs 322 are contracted by the eardrum 321 and spread out into an eight-shaped shape, and the barbs 323 on the barbs 322 are buckled in the rod holes 331 on the main surface 301, so that the barbs 323 are clamped at the first end of the rod hole 331. The puncture hole 332 is formed so that the eardrum 321 close to the main surface 301 can hook the barb 323 into the puncture hole 332 on the main surface 301, thereby realizing the preliminary locking of the triangular piece 2 and the main surface 301; and when the eardrum 321 close to the main surface 301 is in contact, the puncture rod 322 on the eardrum 321 close to the auxiliary surface 302 is directed toward the end position of the rod hole 331 on the auxiliary surface 302, so that when the eardrum 321 close to the main surface 301 contracts, the eardrum 321 close to the auxiliary surface 302 expands to insert the puncture rod 322 into the rod hole 331, and a gap is left between the puncture rod 322 and the rod hole 331 to facilitate the movement of the barb 323 in the rod hole 331.

[0046] The deformation transmission of the two eardrums 321 in the above embodiment can be a rod sliding on the triangular member 2, or a disc provided with a bump and a torsion spring, and a coaxially arranged sprocket transmission, or existing mechanisms or existing components known to those skilled in the art.

[0047] By placing the tenon 1 with the triangular piece 2 on the mortise 11, and making the tenon 1 abut against the main surface 301, the eardrum 321 close to the main surface 301 is contracted, and the gas in the membrane flows to the eardrum 321 close to the secondary surface 302 through the main airway 31, so that the eardrum 321 close to the secondary surface 302 expands and the thorn rod 322 is inserted into the rod hole 331 on the secondary surface 302, and the multiple barbs 323 on the thorn rod 322 are inserted into the multiple thorn holes 332, and at the same time, the eardrum 321 abutting on the main surface 301 is contracted, so that the multiple thorn rods 322 on the eardrum 321 close to the main surface 301 are spread out It is in the shape of a figure eight, and the barbs 323 on the thorn rod 322 are buckled in the rod hole 331 on the main surface 301, so that the barbs 323 are hooked and pulled in the first thorn hole 332 at the end of the rod hole 331, completing the preliminary locking of the triangular piece 2 and the main surface 301, thereby achieving the locking and hooking of the two groups of barbs 323 on the right-angled surface of the triangular piece 2, so that the tenon 1 is limited and fixed on the mortise 11, effectively preventing the tenon 1 from detaching and falling from the mortise 11, and there is no need to hold the tenon 1 and the mortise 11 with one hand, which is convenient for assembling the mortise and tenon building block toys, and increases the fun of playing with the mortise and tenon building block toys.

[0048] As an embodiment further provided by the present invention, a suction hole 33 is provided at the end of the rod hole 331 , a suction cover 32 is provided on the outer side of the eardrum 321 , and the suction cover 32 is in abutment with the suction hole 33 .

[0049] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the suction hole 33 is opened on the secondary surface 302, and the suction cover 32 close to the secondary surface 302 is moved in the suction hole 33, and the suction cover 32 is specifically a stainless steel metal cover.

[0050] By placing the tenon 1 with the triangular piece 2 assembled by snapping on the mortise 11 and making the tenon 1 abut against the main surface 301, the eardrum 321 is contracted by the abutment of the main surface 301, and the suction cover 32 abuts against the main surface 301 to deform and form a suction cup effect. When the barb 323 on the main surface 301 is locked at the position of the first puncture hole 332 on the rod hole 331, the suction cover 32 provides an additional adsorption connection to the main surface 301, thereby increasing the locking stability of the tenon 1 on the main surface 301 of the mortise 11.

[0051] As another embodiment further provided by the present invention, the main air passage 31 is symmetrically and movably arranged with a piston plate 34 and a first sealing plate 35 as demarcations to divide the main air passage 31 into two pressure chambers 341, two air-deficient chambers 342 and a multi-air chamber 352, wherein:

[0052] The triangular member 2 is provided with a secondary air passage 36 for connecting the two pressure chambers 341 and the multi-air chamber 352 , and the two air-deficient chambers 342 are connected to the multi-air chamber 352 .

[0053] Specifically, Figure 5 , Figure 6 and Fig. 9 As shown, the piston plate 34 slides in parallel with the inclined direction of the triangle piece 2, and the first sealing plate 35 is hinged at the port of the multi-air chamber 352, and a torsion spring is arranged at the hinged position, so that the first sealing plate 35 closes the port of the multi-air chamber 352 in the default state, and a blocking plate 351 is fixedly installed on the first sealing plate 35, and when the first sealing plate 35 is deflected by 30°, the blocking plate 351 abuts against the inner wall of the multi-air chamber 352, and a rubber pad is arranged on the contact surface between the blocking plate 351 and the inner wall of the multi-air chamber 352 to provide a sealing effect for the blocking plate 351, and when the multi-air chamber 352 discharges the gas sent from the air-deficient chamber 342 to the secondary air duct 36, the first sealing plate 35 closes the multi-air chamber 352 again under the action of the torsion spring to restore the deformation.

[0054] Furthermore, the pressure chamber 341 and the air-deficient chamber 342 are located on both sides of the piston plate 34, and the pressure chamber 341 is connected to the eardrum 321. The two pressure chambers 341 and the two air-deficient chambers 342 share a multi-air chamber 352, so that the main air channel 31 can work no matter from which end face the tenon 1 is abutted against the mortise 11; the two secondary air channels 36 and the two pressure chambers 341 and the air-deficient chamber 342 are arranged horizontally, and when the gas is flowing, the secondary air channels 36 and the pressure chambers 341 and the air-deficient chamber 342 transfer gas in a cross shape; and one-way membranes (similar to one-way valves, which are prior art and will not be described here) are provided at the ports on both sides of the secondary air channels 36, so that the gas in the secondary air channels 36 has only one-way flow and a sealing effect.

[0055] When the main surface 301 abuts against the tympanic membrane 321 and contracts, the pressure of the pressure chamber 341 near the main surface 301 increases and acts on the piston plate 34, so that the piston plate 34 squeezes the gas in the air-deficient chamber 342 and acts on the first sealing plate 35, so that the first sealing plate 35 deflects and causes the blocking plate 351 to close the port of the secondary airway 36 near the main surface 301, accompanied by the deformation of the torsion spring, so that the compressed gas in the multiple air chambers 352 enters from the port of the secondary airway 36 near the secondary surface 302, and impacts the one-way membrane to make the gas flow through the secondary airway 36 and enter the pressure chamber 341 near the secondary surface 302, so that the tympanic membrane 321 near the secondary surface 302 is expanded by air intake, so that the piercing rod 322 is inserted into the rod hole 331 on the secondary surface 302, and the multiple barbs 323 on the piercing rod 322 are stuck in the multiple puncture holes 332.

[0056] In the above embodiment, the driving source of the piston plate 34 can be a rod directly pushing, or the above sprocket coaxial transmission gear, rack meshing, or existing mechanisms or existing components known to those skilled in the art.

[0057] As another embodiment further provided by the present invention, an air storage chamber 38 is provided on the triangular member 2, and a second sealing plate 371 and a third sealing plate 373 are movably mounted between the auxiliary air passage 36 and the air storage chamber 38, wherein:

[0058] The second sealing plate 371 controls the opening and closing of the secondary air passage 36 and the pressure chamber 341 . The third sealing plate 373 is provided with an elastic component for gradually releasing the third sealing plate 373 to repeatedly connect the air storage chamber 38 and the secondary air passage 36 .

[0059] Specifically, Figure 5 and Figure 7 As shown, the secondary air passage 36 and the air storage chamber 38 are closed / communicated by a second sealing plate 371 and a third sealing plate 373 disposed therebetween.

[0060] Furthermore, a hinge column 37 is circumferentially rotated between the auxiliary air duct 36 and the air storage chamber 38, and a torsion spring is provided at the rotation position of the hinge column 37, and the second sealing plate 371 is fixedly installed on the hinge column 37 so that the second sealing plate 371 closes the auxiliary air duct 36 in a default state, and a plate protrusion 372 is fixedly installed on the hinge column 37, and the third sealing plate 373 is movably sleeved on the hinge column 37, and a torsion spring is provided at the sleeve position of the third sealing plate 373 so that the third sealing plate 373 closes the air storage chamber 38 in a default state, and the angle between the plate protrusion 372 and the third sealing plate 373 is specifically 60° in the default state.

[0061] The compressed gas in the multi-gas chamber 352 enters from the port of the secondary gas channel 36 close to the secondary surface 302 and impacts the one-way membrane to make the gas flow through the secondary gas channel 36 and enter the pressure chamber 341 close to the secondary surface 302. At the same time, the gas flowing in the secondary gas channel 36 impacts the second sealing plate 371 to deflect, so that the plate protrusion 372 abuts against the third sealing plate 373 to deflect. At this time, the angle between the plate protrusion 372 and the third sealing plate 373 is reduced to zero, so that the third sealing plate 373 opens the gas storage chamber 38, and at the same time When the gas in the secondary airway 36 is exhausted, the second sealing plate 371 closes the secondary airway 36 again after the torsion spring recovers its deformation, and the eardrum 321 on the secondary surface 302 expands and inserts the thorn rod 322 into the rod hole 331 on the secondary surface 302, and the multiple barbs 323 on the thorn rod 322 are stuck in the multiple puncture holes 332, and When the gas in the gas storage chamber 38 reaches a critical value and the second sealing plate 371 returns to the default position, the third sealing plate 373 recovers its deformation under the action of the torsion spring without damping, so that the third sealing plate 373 continues to shake and returns to the default state, and at the same time, the angle between the plate protrusion 372 and the third sealing plate 373 changes between 0 and 60 degrees, and returns to the state of the angle of 60 degrees. At this time, the third sealing plate 373 can intermittently release the gas in the gas storage chamber 38, so that the gas storage chamber 38 The gas is injected again into the eardrum 321 close to the secondary surface 302, and under the deformation of the eardrum 321 itself, the thorn rod 322 originally inserted on the secondary surface 302 is repeatedly pushed and pulled, so that the barbs 323 on the thorn rod 322 are repeatedly hooked in the puncture hole 332, so that the barbs 323 on the thorn rod 322 can be hooked and pulled with the puncture hole 332 for many times, thereby reducing the hooking tolerance rate between the barbs 323 and the puncture hole 332, and increasing the locking stability between the tenon 1 and the mortise 11.

[0062] In the above embodiment, the driving source of the second sealing plate 371 can be a rod direct push, or the above sprocket coaxial transmission, or existing mechanisms or existing components known to those skilled in the art.

[0063] As another embodiment further provided by the present invention, a plug cavity 40 and an exhaust passage 44 are provided on the triangular member 2, and a plug sheet 41 is slidably provided in the plug cavity 40, wherein:

[0064] The plug 41 is provided with a sheet hole 412 , and the sheet hole 412 is used to connect the multiple air cavities 352 and the exhaust passage 44 , and the exhaust passage 44 is connected and matched with the suction hole 33 .

[0065] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, a through hole is provided between the plug cavity 40 and the multiple air cavities 352 , and the plug sheet 41 is located in the middle of the plug cavity 40 in a default state, and the sheet hole 412 is connected to the through hole.

[0066] Furthermore, the exhaust duct 44 is symmetrically arranged on the side section of the tenon 1, while the exhaust duct 44 is staggered in the axial direction of the tenon 1; an exhaust port 441 is opened on the end face of the right-angled edge of the triangular piece 2, and the exhaust port 441 is connected to the exhaust duct 44. When the triangular piece 2 abuts against the main surface 301, the exhaust port 441 is connected to the suction hole 33.

[0067] When the tenon 1 is pulled off from the mortise 11 by hard pulling, the excess gas in the multiple air cavities 352 enters the exhaust duct 44 from the through holes and the sheet holes 412, so that the exhaust duct 44 discharges the gas from the exhaust port 441 and enters the suction hole 33, and the gas entering the suction hole 33 enters the multiple rod holes 331, so that the rod holes 331 are filled with air to facilitate the pulling out of the locking barbs 323 on the secondary surface 302.

[0068] In the above embodiment, the driving source of the plug 41 can be a rod directly pushing, or the above sprocket coaxial transmission gear, rack meshing, or existing mechanisms or existing components known to those skilled in the art.

[0069] As another embodiment further provided by the present invention, the triangular piece 2 is provided with symmetrically arranged cavity air passages 421, which are used to connect to the plug cavity 40, and the cavity air passages 421 are connected to the ends thereof with air bags 42;

[0070] The suction cover 32 is used to abut against the airbag 42 to shrink, so as to move the plug 41 and close the multiple air chambers 352 .

[0071] Specifically, Figure 5 and Fig. 9 As shown, the airbag 42 is specifically a rubber bag, the plug 41 has the same function as the piston plate 34 , and the sliding directions of the plug 41 and the piston plate 34 remain parallel.

[0072] By placing the tenon 1 with the triangular piece 2 on the mortise 11 and making the tenon 1 abut against the main surface 301, the eardrum 321 is contracted by the abutment of the main surface 301, and the suction cover 32 abuts against the main surface 301, so that the suction cover 32 is deformed and squeezes the airbag 42, so that the airbag 42 discharges the gas in the bag to the plug cavity 40 through the cavity airway 421, so that the gas pressure increases and squeezes the plug piece 41 to slide translationally, so that the plug piece 41 slides toward the secondary surface 302, so that the sheet hole 412 is away from the through hole, so that the plug piece 41 closes the multiple air cavities 352, and facilitates the gas cross-transmission work of the multiple air cavities 352.

[0073] As another embodiment further provided by the present invention, a ventilation column 43 is movably installed between the plug cavity 40 and the exhaust duct 44 . The ventilation column 43 is provided with a column air hole 431 and is used to connect the plug cavity 40 and the exhaust duct 44 .

[0074] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, a column moving hole 430 is opened on the triangular member 2, and the column moving hole 430 is used to connect the plug cavity 40 and the exhaust passage 44. When the plug plate 41 moves horizontally, the plate hole 412 loses the connection with the column moving hole 430.

[0075] Furthermore, the column air holes 431 are symmetrically arranged on the side section of the ventilation column 43, and the column air holes 431 and the exhaust passage 44 are connected and matched.

[0076] The ventilation column 43 is deflected to allow the column air hole 431 to connect the column movement hole 430 and the exhaust duct 44, so that the excess gas in the multiple air cavities 352 enters the exhaust duct 44 from the through holes and the sheet holes 412, and the gas entering the suction hole 33 enters the multiple rod holes 331, so that the rod holes 331 are filled with air to facilitate the removal of the locking barbs 323 on the secondary surface 302.

[0077] As another embodiment further provided by the present invention, an elastic member 411 and a shifting block 414 are provided on the plug 41, and when the plug 41 is in a movable and offset state, the elastic member 411 is deformed;

[0078] During the recovery process of the elastic member 411 , the shifting block 414 shifts the vent column 43 to deflect back and forth, so as to intermittently connect the plug cavity 40 and the exhaust passage 44 through the column air hole 431 .

[0079] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, the elastic member 411 is fixedly mounted on the plug sheet 41 , and the elastic member 411 is symmetrically arranged. The elastic member 411 is specifically a spring, and the elastic member 411 is in abutment with the inner wall of the plug cavity 40 .

[0080] Furthermore, a bracket 413 is fixedly installed in the sheet hole 412, and a shift block 414 is fixedly installed on the bracket 413, and the bracket 413 is specifically a triangular rod, so that the bracket 413 does not affect the gas flow of the sheet hole 412; a recessed hole is opened on the side wall of the ventilation column 43, so that the shift block 414 can be snap-fitted with the recessed hole.

[0081] The airbag 42 is squeezed by the deformation of the suction cover 32, so that the airbag 42 discharges the gas in the bag to the plug cavity 40 through the cavity airway 421, so that the gas pressure increases and squeezes the plug piece 41 to slide in translation, so that the plug piece 41 slides toward the secondary surface 302. At this time, the elastic member 411 on the plug piece 41 close to the secondary surface 302 abuts against the inner wall of the plug cavity 40 and deforms. When the tenon 1 is hard pulled out from the mortise 11, the airbag 42 close to the main surface 301 expands, so that the plug piece 41 returns to the middle of the plug cavity 40. At the same time, under the action of the elastic member 411 restoring the deformation, it moves closer to the main surface 301, and the elastic member 411 close to the main surface 301 abuts against the inner wall of the plug cavity 40, so that the two elastic members 411 undergo a process of repeated deformation and recovery of the deformation, and in the plug The sheet 41 repeatedly moves and stops under the action of friction, and at this time, the sheet hole 412 can be continuously connected and closed with the through hole. At the same time, the shift block 414 engages with the concave hole to drive the ventilation column 43 to rotate left and right, and makes the column air hole 431 close to the secondary surface 302 repeatedly connect with the exhaust duct 44, so that the multiple air cavities 352 allow the excess internal gas to enter the exhaust duct 44 through the through hole, the sheet hole 412, and the column air hole 431, so that the gas discharged from the exhaust port 441 to the suction hole 33 has an effect of repeated impact, so that the gas entering the rod hole 331 can have additional impact force, increase the effect of the barb 323 being detached from the puncture hole 332, facilitate the detachment and removal of the tenon 1 from the mortise 11, and reduce the difficulty of removing the tenon 1.

[0082] The driving source of the ventilation column 43 in the above embodiment can be a rod member cooperating with a rack or a gear to push the rod directly, or the above sprocket coaxial transmission, or any existing mechanism or existing component known to those skilled in the art.

[0083] As another embodiment further provided by the present invention, an air suction channel 45 connected to the air-deficient cavity 342 is provided on the triangular member 2 , and the airbag 42 contracted to the initial value state is used to release the port of the air suction channel 45 .

[0084] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, a suction port 451 is provided on the right-angle end face of the triangular member 2 , and the suction port 451 is connected to the suction channel 45 so that the suction channel 45 has a larger suction area, and a one-way membrane is fixedly installed at the port of the suction channel 45 close to the air-deficient cavity 342 .

[0085] The tenon 1 abuts against the main surface 301, so that the eardrum 321 is contracted by the abutment of the main surface 301. At the same time, the suction cover 32 abuts against the main surface 301, so that the suction cover 32 is deformed and squeezes the airbag 42, so that the airbag 42 discharges the gas in the bag to the plug cavity 40 through the cavity airway 421. At the same time, the air bag 42 closes the exhaust port 451 during the process of shrinking and deflation, so as to achieve the air supply work without interfering with the air-deficient cavity 342.

[0086] Secondly, when the tenon 1 is pulled out from the mortise 11, the airbag 42 near the main surface 301 expands, and the airbag 42 loses its closure on the air extraction port 451, so that a negative pressure is formed due to the lack of gas in the air-deficient cavity 342, and the air-deficient cavity 342 extracts air to the main surface 301 through the air extraction channel 45 and the air extraction port 451. At this time, the tenon 1 has just been removed from the mortise 11, so that there is still a small distance between the right-angle end face of the triangular piece 2 and the main surface 301, so that the air extraction port 451 is not closed. 451 draws air between the right-angled end face of the triangular piece 2 and the main face 301, so that the secondary face 302 has an additional adsorption effect opposite to the main face 301 at a right angle, so that during the hard pulling out process of the barbs 323 on the secondary face 302, the adsorption effect formed between the other right-angled end face of the triangular piece 2 and the main face 301 can reduce the detachment rate of the tenon 1, thereby preventing the tenon 1 from falling directly due to lack of holding during the detachment process from the mortise 11, and reducing the problem of the tenon 1 being damaged by falling and impact.

[0087] As another embodiment further provided by the present invention, an arc hole 46 is opened on the triangular member 2 , and the arc hole 46 is used to connect the exhaust passage 44 and the suction passage 45 .

[0088] Specifically, Figure 5 , Figure 8 and Fig. 9 As shown, the exhaust duct 44 is symmetrically arranged on the side section of the triangle 2, and the arc hole 46 connects the exhaust duct 44 near the secondary surface 302 and the exhaust duct 45 near the main surface 301, and the two symmetrically arranged arc holes 46 do not interfere with each other.

[0089] During the process of forcibly pulling the tenon 1 off the mortise 11, the air bag 42 near the main surface 301 expands, so that the plug 41 returns to the middle of the plug cavity 40, and at the same time, the elastic member 411 moves closer to the main surface 301 under the action of restoring the deformation, and the elastic member 411 near the main surface 301 abuts against the inner wall of the plug cavity 40, so that the two elastic members 411 undergo a process of repeated deformation and deformation recovery, and the plug 41 stops moving under the action of repeated movement and friction, and at this time, the sheet hole 412 can be continuously connected and closed with the through hole, and at the same time, the shift block 414 engages with the concave hole to drive the ventilation column 43 to rotate left and right, and the column air hole 431 close to the secondary surface 302 is repeatedly connected to the exhaust channel 44, so that the multi-cavity 352 allows the excess gas inside to enter the exhaust channel 44 through the through hole, sheet hole 412, and column air hole 431, so that the gas discharged from the exhaust port 441 to the suction hole 33 has repeated impact The effect is to achieve that the gas entering the rod hole 331 can have an additional impact force, thereby increasing the effect of the barb 323 being separated from the puncture hole 332. At the same time, when the airbag 42 expands and loses the closure of the air suction port 451, a negative pressure is formed due to the lack of gas in the air-deficient cavity 342, and the air-deficient cavity 342 draws air toward the main surface 301 through the air suction duct 45 and the air suction port 451. At this time, under the opposite action of the gas flowing in the exhaust duct 44 and the air suction duct 45, the arc hole 46 plays a connecting role, and the exhaust duct 44 forms a negative pressure extraction, and the air suction duct 45 forms additional air replenishment, so that the arc hole 46 simultaneously accelerates the gas flow in the exhaust duct 44 and the air suction duct 45, and additionally increases the separation of the barb 323 on the secondary surface 302 and the adsorption force on the main surface 301, thereby increasing the stability of the tenon 1 from the mortise 11, and greatly reducing the possibility of the tenon 1 being damaged by falling and impact.

[0090] Working principle: by placing the tenon 1 with the triangular piece 2 on the mortise 11, and making the tenon 1 abut against the main surface 301, the pressure of the pressure chamber 341 close to the main surface 301 is increased and acts on the piston plate 34, so that the piston plate 34 squeezes the gas in the air-deficient chamber 342 and acts on the first sealing plate 35, so that the first sealing plate 35 deflects and makes the blocking plate 351 close the port of the secondary airway 36 close to the main surface 301, and at the same time, the torsion spring is formed. The compressed gas in the multiple air chambers 352 enters from the port of the secondary air channel 36 near the secondary surface 302, and impacts the one-way membrane to make the gas flow through the secondary air channel 36 and enter the pressure chamber 341 near the secondary surface 302, thereby expanding the eardrum 321 near the secondary surface 302 and inserting the thorn rod 322 into the rod hole 331 on the secondary surface 302, and accompanied by the multiple barbs 323 on the thorn rod 322 being stuck in the multiple puncture holes 332, and at the same time, the eardrum abutting on the main surface 301 is The 321 is contracted so that the multiple thorn rods 322 on the eardrum 321 close to the main surface 301 are spread out in an eight-shaped shape, and the barbs 323 on the thorn rods 322 are buckled in the rod holes 331 on the main surface 301, so that the barbs 323 are hooked and pulled in the first thorn hole 332 at the end of the rod hole 331, completing the preliminary locking of the triangular piece 2 and the main surface 301, so that the two groups of barbs 323 on the right-angled surface of the triangular piece 2 are locked and hooked, so that the tenon 1 is locked in the mortise 1. 1 is limited and fixed, so as to effectively prevent the tenon 1 from falling off from the mortise 11; and when the tenon 1 abuts against the main surface 301, the eardrum 321 is abutted and contracted by the main surface 301, and the suction cover 32 abuts against the main surface 301, so that the suction cover 32 is deformed and forms a suction cup effect, so that when the barb 323 on the main surface 301 is locked at the position of the first puncture hole 332 on the rod hole 331, the suction cover 32 provides an additional adsorption connection to the main surface 301.

[0091] Secondly, the compressed gas in the multi-gas chamber 352 enters from the port of the secondary gas channel 36 near the secondary surface 302, and impacts the one-way membrane to make the gas flow through the secondary gas channel 36 and enter the pressure chamber 341 near the secondary surface 302. At the same time, the gas flowing in the secondary gas channel 36 impacts the second sealing plate 371 to deflect, so that the plate protrusion 372 abuts against the third sealing plate 373 to deflect. At this time, the angle between the plate protrusion 372 and the third sealing plate 373 is reduced to zero, so that the third sealing plate 373 closes the gas storage chamber 38 is opened, and at the same time, the torsion spring on the third sealing plate 373 recovers its deformation, so that part of the gas flowing in the auxiliary airway 36 enters the gas storage chamber 38 for storage. When the gas in the auxiliary airway 36 is exhausted, the second sealing plate 371 closes the auxiliary airway 36 again after the torsion spring recovers its deformation, and the eardrum 321 on the secondary surface 302 expands and inserts the thorn rod 322 into the rod hole 331 on the secondary surface 302, and the multiple barbs 323 on the thorn rod 322 are stuck in The third sealing plate 373 is provided with a plurality of puncture holes 332, and when the gas in the gas storage chamber 38 reaches a critical value and the second sealing plate 371 returns to the default position, the third sealing plate 373 is deformed again under the action of the torsion spring without damping, so that the third sealing plate 373 continuously shakes and returns to the default state, and at the same time, the angle between the plate protrusion 372 and the third sealing plate 373 changes between 0 and 60 degrees, and returns to the state of the angle of 60 degrees, and at this time, the third sealing plate 373 can adjust the gas in the gas storage chamber 38. The body is intermittently released, so that the gas storage chamber 38 injects the gas into the eardrum 321 close to the auxiliary surface 302 again, and under the deformation of the eardrum 321 itself, the thorn rod 322 originally inserted on the auxiliary surface 302 is repeatedly pushed and pulled, so that the barbs 323 on the thorn rod 322 are repeatedly hooked in the puncture hole 332, so that the barbs 323 on the thorn rod 322 can be hooked and pulled with the puncture hole 322 for many times, thereby reducing the hooking tolerance rate between the barbs 323 and the puncture hole 332.

[0092] Furthermore, when the tenon 1 with the triangular piece 2 is placed on the mortise 11, and the tenon 1 is abutted against the main surface 301, so that the eardrum 321 is abutted and contracted by the main surface 301, the suction cover 32 abuts against the main surface 301, so that the suction cover 32 is deformed and squeezes the airbag 42, so that the airbag 42 discharges the gas in the bag to the plug cavity 40 through the cavity airway 421, so that the gas pressure increases and squeezes the plug 41 to slide translationally, so that the plug 41 slides toward the secondary surface 302, so that the sheet hole 412 is away from the through hole, so that the plug 41 closes the multiple air cavities 352. At this time, the elastic member 411 on the plug 41 close to the secondary surface 302 abuts against the inner wall of the plug cavity 40 and is deformed. When the tenon 1 is forcibly pulled off from the mortise 11, the airbag 42 close to the main surface 301 is expanded, so that the plug 41 returns to the middle of the plug cavity 40. At the same time, Under the action of restoring deformation, 411 moves closer to the main surface 301, and the elastic member 411 close to the main surface 301 abuts against the inner wall of the plug cavity 40, so that the two elastic members 411 undergo a process of repeated deformation and deformation recovery, and stop moving under the action of repeated movement and friction of the plug sheet 41, and at this time, the sheet hole 412 can be continuously connected and closed with the through hole, and at the same time, the shift block 414 engages with the recessed hole to drive the ventilation column 43 to rotate left and right, and the column air hole 431 close to the secondary surface 302 is repeatedly connected to the exhaust channel 44, so that the multi-cavity 352 allows the excess gas inside to enter the exhaust channel 44 through the through hole, sheet hole 412, and column air hole 431, so that the gas discharged from the exhaust port 441 to the suction hole 33 has a repeated impact effect, so that the gas entering the rod hole 331 can have additional impact force, thereby increasing the effect of the barb 323 being separated from the puncture hole 332.

[0093] Furthermore, when the tenon 1 is pulled out from the mortise 11, the airbag 42 near the main surface 301 expands, and the airbag 42 loses the closure of the air extraction port 451, so that a negative pressure is formed due to the lack of gas in the air-deficient cavity 342, and the air-deficient cavity 342 extracts air to the main surface 301 through the air extraction channel 45 and the air extraction port 451. At this time, the tenon 1 has just been removed from the mortise 11, so that there is still a relatively large gap between the right-angle end face of the triangular piece 2 and the main surface 301. The small spacing allows the air outlet 451 to draw air between the right-angled end face of the triangular piece 2 and the main face 301, so that the secondary face 302 has an additional adsorption effect on the right-angled main face 301, so that during the hard pulling process of the barbs 323 on the secondary face 302, the adsorption effect formed between the other right-angled end face of the triangular piece 2 and the main face 301 can reduce the detachment rate of the tenon 1, thereby preventing the tenon 1 from falling directly due to lack of holding during the detachment process from the mortise 11.

[0094] Finally, synchronously, under the action of the opposite directions of the gases flowing inside the exhaust duct 44 and the air extraction duct 45, the arc hole 46 plays a connecting role, and the exhaust duct 44 forms a negative pressure extraction, and the air extraction duct 45 forms additional air supply, so that the arc hole 46 simultaneously accelerates the gas flow inside the exhaust duct 44 and the air extraction duct 45, and additionally increases the detachment of the barbs 323 on the secondary surface 302 and the adsorption force on the main surface 301, thereby increasing the stability of the tenon 1 from the mortise 11, and greatly reducing the possibility of the tenon 1 being damaged by falling and impact.

[0095] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
