Description
Technical Field
The invention relates to the technical field of accessories for fixedly connecting workpieces, in particular to a locking connection accessory mechanism which is very simple, convenient, quick and firm to use.
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.

When the embedded body 1 is used, as shown in fig. 1, the embedded body 1 is embedded in a cavity 200 reserved in advance on a plate 100, pin holes for allowing the bayonet pins 21 to penetrate are correspondingly formed in the surface of the plate 100, when the embedded body 1 is embedded in the cavity 200 of the plate 100, the bayonet pins 21 are pressed downwards, the elastic force of the return spring 22 is overcome, the top ends of the bayonet pins 21 are flush with the surface of the embedded body 1, then the embedded body 1 is pushed into the cavity 200, and after the embedded body 1 is pushed to a preset position, the bayonet pins 21 automatically extend out of the pin holes of the plate, so that the embedded body 1 is clamped in the cavity 200 of the plate 100, and the purpose of installing and fixing the embedded body 1 in the plate 100 is achieved.
Similarly, as shown in fig. 5 and 8, the fixing mechanism 2 on the clasping latch seat 4 may also adopt such a scheme, specifically as follows: the mounting and fixing mechanism 2 is composed of a bayonet 21 and a return spring 22, and the bottom of the bayonet 21 is also provided with a limit ring part 23. The rear end of the clasping and locking seat 4 is a square body with a hollow structure, and the rear end of the clasping and locking seat 4 is also provided with a clamping pin hole 11. The bayonet 21 is sleeved in the pin hole 11, and the limit ring part 23 is abutted against the hole edge of the bayonet hole 11, so that the bayonet 21 is limited on the rear end of the clasping lock seat 4 without departing from the bayonet hole 11. Reset spring 22 inlays in embracing the rear end of padlock seat 4, just reset spring 22's one end is supported and is leaned on bayonet lock 21's bottom, reset spring 22's the other end supports and leans on embracing the inner chamber wall of padlock seat 4 rear end to under reset spring 22 effect, bayonet lock 21's upper end is and stretches out and set up outside embracing the rear end of padlock seat 4. At this time, the clasping lock seat 4 of the mounting and fixing mechanism 2 having this structure is mounted in the cavity 200 of the other plate 100, as in the case of the insert 1 of the mounting and fixing mechanism 2 having this structure.
Alternatively, as shown in fig. 2 and 6, the attachment fixing mechanism 2 is a compression/expansion fixing mechanism including a fixed block 24 having a slant concave surface 241, a movable block 25 having a slant surface 251, and a bolt 26. The fixing block 24 is fixedly mounted on the side surface of the embedded body 1 or the clasping lock seat 4, specifically, the fixing block 24 can be fixedly mounted on the side surface of the embedded body 1 or the clasping lock seat 4 by adopting a screw or screw hole manner, that is, as shown in fig. 2. Of course, the side surface of the embedded body 1 or the clasping lock seat 4 may be directly machined and formed by adopting an integral machining and forming mode, namely the mode shown in fig. 6.
As shown in fig. 2, the movable block 25 is embedded in the inclined concave surface 241 of the fixed block 24, the inclined surface 251 of the movable block 25 and the inclined concave surface 241 of the fixed block 24 are tapered inclined surfaces with opposite directions, and the inclined surface 251 and the inclined concave surface 241 are attached together.
