Background
In the assembly and fixation of the existing workpieces, the most common way is to fix the workpieces by self-tapping screws. For example, in the assembly of an all-aluminum furniture cabinet, when aluminum alloy plates are fixedly connected with each other, an aluminum alloy square bar is fixed on the side surface of one aluminum alloy plate by using a self-tapping screw; the end surface of the other aluminum alloy plate is provided with a groove which is embedded on the aluminum alloy square strip, and then the groove is locked into the aluminum alloy square strip by a self-tapping screw from the outer side of the groove to realize the vertical assembly and connection between the two aluminum alloy plates. In practical applications, the method mainly has the following defects: firstly, the self-tapping screws are adopted for fixed connection, the engagement contact area between the self-tapping screws and the aluminum alloy materials is small, and when the connected aluminum alloy plates are under the action of external force, the connection parts of the self-tapping screws are easy to deform and tear, so that the firmness and reliability of assembly connection between the aluminum alloy plates are influenced; secondly, the self-tapping screws are adopted for fixed connection, one self-tapping screw cannot be fixed generally, but a plurality of self-tapping screws are adopted for multi-point type fixation, so that a plurality of screw heads are usually left on the surface of the aluminum alloy plate and are displayed outside, and the attractiveness and the grade of the all-aluminum furniture cabinet are influenced; thirdly, self-tapping screws are adopted for fixed connection, and the same screw hole position cannot be restored after being expanded once and cannot be locked when being used repeatedly, so that the all-aluminum furniture cabinet cannot be assembled and disassembled repeatedly, and the moving of the all-aluminum furniture cabinet is greatly influenced; fourthly, because of no elastic squeezing or tensioning force, after the aluminum alloy plate is assembled, a large gap is left between the contact surfaces of the aluminum alloy plate and the aluminum alloy plate, the assembling tightness is poor, and the assembling quality is poor. Therefore, based on the defects of the existing tapping screw connection and fixation method, the applicant believes that a brand new assembly and connection mechanism is needed to be developed to replace the existing tapping screw fixation method, so as to overcome various defects caused by the existing tapping screw assembly and fixation method, enable the all-aluminum furniture cabinet to be assembled more firmly, reliably, durably and beautifully, and realize repeated lossless assembly and disassembly, and further enable all-aluminum furniture products to better meet the requirements of people.

Detailed Description
The first embodiment is as follows:
as shown in fig. 1 and 2, the hidden type buckle locking and connecting structure for connecting plates comprises an embedded body 1 with a hollow structure, a bayonet 2, a spring 3, a lock pin 4, a bayonet head 5, a compact rubber ring 6 and the like.
As shown in fig. 8, fig. 1, and fig. 2, a pin hole 11 for receiving the bayonet 2 is formed in one side surface of the insert 1. The bayonet 2 is sleeved in the pin hole 11, and the bottom end of the bayonet 2 is further provided with a limiting part 21, and the limiting part 21 is abutted against the hole edge of the pin hole 11, so that the bayonet 2 is limited on the embedded body 1 without departing from the pin hole 11.
As shown in fig. 1 or fig. 2, the spring 3 is embedded in the embedded body 1, one end of the spring 3 abuts against the bottom end of the bayonet lock 2, and the other end of the spring 3 abuts against the inner cavity wall of the embedded body 1, so that under the action of the spring 3, the upper end of the bayonet lock 2 extends out of the embedded body 1. When the embedded body 1 is to be inserted into the cavity or the groove of the plate 300, a clamping hole 500 which penetrates through the cavity 400 or the groove is firstly formed on the outer side surface of the plate, the bayonet lock 2 on the embedded body 1 is pressed down, the embedded body 1 is inserted into the cavity or the groove, after the embedded body 1 reaches a preset position, the bayonet lock 2 extends out of the clamping hole 500 of the plate 300 under the action of the spring 3 through the bayonet lock 2, and the embedded body 1 is embedded and fixed on the plate 300, namely, as shown in fig. 1.
As shown in fig. 1 or fig. 2, the rear end of the lock pin 4 is fixedly mounted on the embedded body 1, and the lock pin 4 and the bayonet lock 2 are arranged on the embedded body 1 at an angle of 90 degrees, that is, similar to the arrangement shown in fig. 1 or fig. 2, the bayonet lock 2 is located in the vertical direction, and the lock pin 4 is located in the horizontal direction, thereby forming an arrangement statement at an angle of 90 degrees.
As shown in fig. 7, the locking head 5 is fixedly mounted on the front end of the lock pin 4, a clamping ring groove 7 is formed between the inner side of the locking head 5 and the front end of the lock pin 4, and a tightening rubber ring 6 is further fitted over the clamping ring groove 7. As shown in fig. 1, when a 90-degree vertical assembly connection between one horizontal plate and another vertical plate is to be realized, a locking hole 100 is further formed in the plate 300 in the vertical direction, and the shape and structure of the locking hole 100 are as follows: the rear cavity is composed of an upper perforation 901, a lower perforation 902 and a rear cavity 903, wherein the aperture of the upper perforation 901 is larger than that of the lower perforation 902. The pore structure of this configuration can be seen with reference to fig. 5 or 6. After the locking head 5 extends to the upper through hole 901 of the locking hole 100, the plate 300 in the transverse direction is pushed and knocked downwards, the lock pin 4 moves downwards to the lower through hole 902, the clamping ring groove 7 is embedded into the hole edge of the lower through hole 902, the locking head 5 is locked on the position of the lower through hole 902 by elastic compression formed by the compact rubber ring 6 and cannot exit from the locking hole 100, and the purpose of firm locking is achieved. During disassembly, the locking head 5 can be separated from the lower through hole 902 only by pushing and knocking the plate 300 in the transverse direction upwards, and finally taken out from the upper through hole 901, so that the disassembly and the separation of the plate 300 in the transverse direction and the plate 300 in the vertical direction are completed. The structural design of the invention can realize repeated assembly and disassembly of the plates, does not damage the plates, and is particularly suitable for assembly and connection between the plates on the plate-type furniture or the all-aluminum plate-type furniture.
As shown in fig. 2, the inner side surface of the locking head 5 is a slope structure 600. That is, the solution of fig. 2 is different from the solution of fig. 1 in the slope structure of the locking head 5. With the design of the inclined plane structure, the width of the clamping ring groove 7 can be properly reduced, and the clamping lock head 5 can obtain firmer clamping force in the process of moving the lower through hole 902 from the upper through hole 901 by utilizing the inclined plane structure. Alternatively, the inner side surface of the tightening rubber ring 6 is a slope structure 600, so that the firm clamping force can be obtained.
As shown in fig. 1, 7, 9 and 10, in the specific implementation process, according to the different nesting ways and numbers of the tight rubber rings 6, a plurality of different schemes can be formed: for example, as shown in fig. 1, tightening rubber rings 6 are respectively sleeved on the left and right sides of the clamping ring groove 7 to obtain a firm clamping and fixing force. For example, as shown in fig. 7, a tightening rubber ring 6 is fitted to one side of the clamping ring groove 7, and an inner side surface of the locking head 5 is formed in a slope structure 600 to obtain a clamping fixing force for locking. Or as shown in fig. 9, a tightening rubber ring 6 is sleeved on the right side of the clamping ring groove 7, and the inner side surface of the tightening rubber ring 6 is made into an inclined surface structure 600 to obtain the clamping fixing force for locking. Alternatively, as shown in fig. 10, a tightening rubber ring 6 is fitted to the right side of the clip fitting ring groove 7 to obtain a clamping fixing force for locking. Among the solutions shown in fig. 1, 7, 9 and 10, there is a slight difference in the degree of obtaining the amount of the clamping force for locking, and in practical application, the solutions can be selected and implemented according to the requirements of practical application and the requirements of production cost control.
