Description
Technical Field
[0001] This application relates to the technical field of PCB board processing auxiliary devices, and specifically discloses an adjustable PCB board fixing buckle. Background Art
[0002] During the production and processing of PCB boards, it is necessary to drill holes on their surfaces to facilitate the installation of components for later use. During the drilling process, a fixing tooling is usually used to limit and fix the PCB board to ensure the accuracy of drilling. The fixing tooling used in PCB board production and processing generally includes a fixing base for vertically supporting and fixing the bottom of the PCB board and a buckle structure for limiting and fixing the top of the PCB board. The buckle structure and the fixing base are usually detachably connected.
[0003] The existing buckle structure for fixing and limiting the top of the PCB board is usually an integrally formed buckle structure, that is, one end is detachably connected to the fixing base, and the other end is provided with a limiting groove that can directly accommodate the top of the PCB board. However, the integrally structured buckle structure is fixedly non-adjustable, so that the distance between the limiting groove and the fixing base is also limited and non-adjustable, ultimately limiting its scope of use. As a result, a buckle structure is only limited to being used in the processing of a PCB board in combination with the same unchanged fixing base structure. Especially in the production of PCB boards with a large production scale and a large variety of products, it is necessary to customize special fixing tooling for each type of PCB board, which greatly increases the production cost and production workload. Therefore, in view of this, the inventor provides an adjustable PCB board fixing buckle to solve the above problems. Summary of the Utility Model
[0004] The purpose of the present utility model is to solve the problem that the buckle structure of the fixing tooling used in traditional PCB board processing and production is an integrated and fixedly non-adjustable structure, which limits its scope of use and increases the production cost and production workload.
[0005] To achieve the above purpose, the basic scheme of the present utility model provides an adjustable PCB board fixing buckle, which includes a fixing buckle detachably connected to a fixing base at one end and an elastic adjustment buckle detachably connected to the other end of the fixing buckle. A fixing card slot for accommodating the top of the PCB board is provided on the bottom side of one end of the elastic adjustment buckle. A guide block is provided on the bottom side of the other end of the elastic adjustment buckle, and an elastic clamping block located above the guide block is provided on the top side of the other end of the elastic adjustment buckle. An insertion groove for accommodating the guide block is provided on the side of the fixing buckle close to the elastic adjustment buckle, and a plurality of clamping grooves for accommodating the elastic clamping block are further provided on the top of the fixing buckle. The elastic clamping block includes an elastic limiting rod provided at the top end of one side of the elastic adjustment buckle and a plurality of clamping blocks evenly provided on the side of the elastic limiting rod close to the guide block and engaging with the clamping grooves.
[0006] The principle and effect of this basic solution are as follows:
[0007] 1. Compared with the prior art, by providing a detachable snap connection between the fixed buckle and the elastic adjustment buckle, the present utility model makes the operation of limiting and fixedly installing the PCB board more convenient. By providing an elastic limiting rod and a snap block at the bottom of the elastic limiting rod that is tightly engaged and installed with the snap groove, not only can the rotation movement of the fixed buckle, the elastic adjustment buckle, and the PCB board be restricted by combining the snap connection between the fixed seat and the fixed buckle, improving the structural stability, but also it is convenient to adjust the fixed position of the elastic adjustment buckle on the fixed buckle, making the fixed distance and snap connection specifications of the overall fixed buckle structure adjustable, increasing the usage range of the fixed buckle and the elastic adjustment buckle and the types of applicable products, standardizing the fixed tooling for production use, and expanding the applicable range, thus greatly saving the mold manufacturing cost of the fixed tooling, avoiding the development of mold manufacturing work, thereby reducing the production workload. It not only ensures the installation limit and structural stability of the PCB board, but also has a simple overall structure and is convenient for disassembly and assembly, solving the problem that the snap structure of the fixed tooling used in the traditional PCB board processing and production is integrated and non-adjustable, resulting in a limited usage range, increased production costs, and increased production workload.
[0008] Furthermore, the guiding block includes a straight guiding block provided at the bottom side of one end of the elastic adjustment buckle and an inclined guiding block provided between the bottom end of the straight guiding block and the bottom of one end of the elastic adjustment buckle. The width of the straight guiding block is greater than the width of the inclined guiding block. The guiding groove includes a straight guiding groove provided on the side of the fixed buckle close to the elastic adjustment buckle for accommodating the straight guiding block and an inclined guiding groove opened on the bottom surface of the straight guiding groove for accommodating the inclined guiding block. The width of the inclined guiding groove is less than the width of the straight guiding groove. By providing the straight guiding block, the inclined guiding block, the straight guiding groove, and the inclined guiding groove, it provides a guiding function for the installation and disassembly of the elastic adjustment rod, making the installation more accurate and rapid. By setting the width of the straight guiding block to be greater than the width of the inclined guiding block, while guiding the elastic adjustment buckle, it can also provide a vertical structural support force and limit for the elastic adjustment buckle after installation.
[0009] Furthermore, a retreat groove vertically penetrating to the bottom of the fixed block is provided on the bottom surface of the inclined guiding groove near the outer end. By providing the retreat groove, it provides sufficient snap adaptation space for the elastic adjustment buckle during the installation and disassembly process with the fixed buckle.
[0010] Further, a chamfered convex block is provided at the end of the straight insertion block, and the sum of the lengths of the straight insertion block and the chamfered convex block is less than the straight length of the straight insertion slot. By providing the chamfered convex block, it is more convenient to install the straight insertion block and the inclined insertion block into the insertion slot. By restricting the length relationship between the straight insertion block and the chamfered convex block and the straight insertion slot, the straight insertion slot can sufficiently accommodate the straight insertion block and the chamfered convex block, further facilitating the installation of the structure.
[0011] Further, an insertion chamfer is provided at the port of the straight insertion slot. By providing the insertion chamfer, the port area of the insertion slot is enlarged, facilitating the more rapid insertion of the chamfered convex block and the straight insertion block into the straight insertion slot.
[0012] Further, a stepped through hole through which the top of the fixing seat can pass is provided at one end of the top of the fixing buckle away from the elastic adjustment buckle. A plurality of locking card slots are evenly provided on the peripheral side of the top of the fixing seat, and a plurality of locking blocks that cooperate with the locking card slots for clamping are evenly provided on the inner peripheral side of the stepped through hole. By providing the stepped through hole, it is convenient to install the top of the fixing seat and the fixing buckle. By providing the locking card slots and the locking blocks, the rotational movement of the fixing buckle on the fixing seat is restricted, further improving the stability of the structure.

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0021] As Figure 1 shown, the fixing tooling generally used in the current production and processing of the PCB board 8 generally includes a fixing seat 9 for vertically supporting and fixing the bottom of the PCB board 8 and a buckling structure 10 for limiting and fixing the top of the PCB board 8. The buckling structure 10 and the fixing seat 9 usually adopt detachable clamping. The existing buckling structure 10 for fixing and limiting the top of the PCB board 8 is usually an integrally formed buckling structure 10, that is, one end is clamped with the fixing seat 9, and the other end is provided with a limiting slot that can directly accommodate the top of the PCB board 8 therein.
[0022] An adjustable fixing buckle for the PCB board 8, as shown in the embodiment Figure 2 shown: includes a fixing buckle 1 detachably clamped with the fixing seat 9 at the left end and an elastic adjusting buckle 2 detachably clamped with the right end of the fixing buckle 1. A fixing card slot 3 for accommodating the top of the PCB board 8 is provided at the bottom side of the right end of the elastic adjusting buckle 2. A guiding block 4 is provided at the bottom side of the left end of the elastic adjusting buckle 2. An elastic clamping block 5 is further provided at the top side of the left end of the elastic adjusting buckle 2 above the guiding block 4. An introducing slot for accommodating the guiding block 4 is provided on the side of the fixing buckle 1 close to the elastic adjusting buckle 2. A plurality of clamping slots 20 for accommodating the elastic clamping block 5 are provided at the top of the fixing buckle 1. As Figure 5 shown, the elastic clamping block 5 includes an elastic limiting rod 6 provided at the top end of the left side of the elastic adjusting buckle 2 and a plurality of clamping blocks 7 evenly provided at the bottom side of the elastic limiting rod 6 close to the guiding block 4 and in clamping fit with the clamping slots 20. In order to make the installation specifications and usage ranges of the elastic adjusting buckle 2 and the fixing buckle 1 more extensive, the number of the clamping blocks 7 and the clamping slots 20 can be set to be more, and the distance between each clamping block 7 and the distance between each clamping slot 20 can be set to be smaller values. Among them, the number of the clamping blocks 7 and the clamping slots 20 includes but is not limited to five, and the distance between each clamping block 7 and the distance between each clamping slot 20 includes but is not limited to 0.5 times the width of the clamping block 7.
[0023] Among them, as Figure 5As shown, the guiding block 4 includes a straight guiding block 11 provided at the bottom side of the left end of the elastic adjusting buckle 2 and an inclined guiding block 12 provided between the bottom end of the straight guiding block 11 and the bottom of the left end of the elastic adjusting buckle 2. The width of the straight guiding block 11 is greater than that of the inclined guiding block 12, such as Figure 1 and Figure 4 As shown, the guiding groove includes a straight guiding groove 13 provided on the right side of the fixing buckle 1 close to the elastic adjusting buckle 2 for accommodating the straight guiding block 11 and an inclined guiding groove 14 opened on the bottom surface of the straight guiding groove 13 for accommodating the inclined guiding block 12. The width of the inclined guiding groove 14 is smaller than that of the straight guiding groove 13.
[0024] Among them, as Figure 3 shown, a retreat groove 15 vertically penetrating to the bottom of the fixing block is provided on the bottom surface of the inclined guiding groove 14 near the outer end. A chamfered convex block 16 is provided at the end of the straight guiding block 11. The sum of the lengths of the straight guiding block 11 and the chamfered convex block 16 is smaller than the straight length of the straight guiding groove 13, such as Figure 3 and Figure 4 shown, an inlet chamfer 17 is also provided at the port of the straight guiding groove 13.
[0025] Among them, as Figure 3 shown, a stepped through hole 18 through which the top of the fixing seat 9 can pass is provided at the left end of the top of the fixing buckle 1 away from the elastic adjusting buckle 2. Three locking grooves are evenly provided on the peripheral side of the top of the fixing seat 9. Three locking blocks 19 that cooperate with the locking grooves for clamping are evenly provided on the inner peripheral side of the stepped through hole 18.
[0026] In the specific implementation process of the present utility model, according to the installation position of the PCB board 8 on the fixed seat 9 and the distance between the PCB board 8 and the fixed seat 9, the clamping block 7 at the leftmost end of the elastic adjustment buckle 2 is pre-selected and determined which clamping groove 20 on the fixed buckle 1 it needs to be clamped with. After determination, the elastic adjustment buckle 2 and the fixed buckle 1 are directly buckled and installed. During the process of their buckling and installation, the straight guiding block 11 is slowly pushed into the straight guiding groove 13 along the guiding chamfer 17, and at the same time, the inclined guiding block 12 is also pushed into the inclined guiding groove 14 along with the straight guiding block 11. During this process, it is necessary to continuously apply an upward force to the left end of the elastic limiting rod 6 to lift its left end, thereby increasing the port opening degree of the open end of the elastic adjustment buckle 2 until the entire elastic adjustment buckle 2 is pushed along the guiding groove to the position of the pre-determined clamping groove 20, then stop and cancel the force applied to the left end of the elastic adjustment buckle 2, so that the clamping block 7 of the elastic adjustment buckle 2 is inserted into the clamping groove 20 located below it, completing the snap connection of the fixed block and the elastic adjustment buckle 2. Then, the locking block 19 in the stepped through hole 18 of the fixed buckle 1 is inserted into the locking slot on the top of the fixed seat 9, and at the same time, the fixed clamping groove 3 of the elastic adjustment buckle 2 is also inserted into the top of the PCB board 8 fixed on the fixed seat 9, thus completing the limit clamping and fixing of the top of the PCB board 8.
[0027] Compared with the prior art, by setting the detachable snap connection between the fixed buckle 1 and the elastic adjustment buckle 2, the present utility model makes the operation of limiting and fixing the installation of the PCB board 8 more convenient. By setting the elastic limiting rod 6 and arranging the clamping block 7 at the bottom of the elastic limiting rod 6 which is clamped and fitted with the clamping groove 20, it can not only combine the clamping of the fixed seat 9 and the fixed buckle 1 to limit the rotational movement of the fixed buckle 1, the elastic adjustment buckle 2 and the PCB board 8, improve the structural stability, but also facilitate the adjustment of the fixed position of the elastic adjustment buckle 2 on the fixed buckle 1, making the fixed distance and the clamping specifications of the overall fixed snap structure 10 adjustable, increasing the usage range of the fixed buckle 1 and the elastic adjustment buckle 2 and the types of applicable products, standardizing the production and use of the fixed tooling, and expanding the applicable range. Thus, it greatly saves the mold manufacturing cost of the fixed tooling, avoids the development of mold manufacturing work, thereby reducing the production workload. It not only ensures the installation limit and structural stability of the PCB board 8, but also has a simple overall structure, is convenient for disassembly and assembly, solving the problem that the snap structure of the fixed tooling used in the traditional PCB board processing and production is integrated and non-adjustable, resulting in its limited usage range, increased production cost and production workload.
