Detailed Implementation

[0031] The present invention will now be described in conjunction with specific embodiments.

[0032] Example 1, as Figures 1 to 5 As shown, an improved stacking spray clamping device includes a clamping base plate 1, a clamping cover plate 2, a locking pin 4, and several clamping middle plates 3. The clamping base plate 1 is provided with an upward protruding base plate positioning protrusion 11, the clamping cover plate 2 is provided with a downward protruding cover plate positioning protrusion 21, and each clamping middle plate 3 is provided with a middle plate positioning protrusion 31.

[0033] Among them, such as Figures 2 to 4 As shown, the clamping base plate 1 has a base plate through hole 12 corresponding to the locking pin 4, and the clamping cover plate 2 has a cover plate through hole 22 corresponding to the locking pin 4. The locking pin 4 includes a limiting stop part 41, a straight rod part 42, and an elastic buckle part 43 connected sequentially from bottom to top. An elastic element is installed at the lower end of the straight rod part 42 above the limiting stop part 41.

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, the clamping cover plate 2 is provided with a downward protruding cover plate contour positioning pin 23 corresponding to the structural hole of the sprayed product. The cover plate contour positioning pin 23 and the clamping cover plate 2 are an integral structure.

[0035] Furthermore, such as Figure 2 and Figure 5 As shown, each clamping plate 3 has a downward-protruding center plate positioning pin 32 corresponding to the structural hole of the sprayed product. Each center plate positioning pin 32 and the corresponding clamping plate 3 are an integral structure.

[0036] In addition, such as Figure 2 As shown, the elastic buckle part 43 of the locking pin 4 includes two elastic buckle arms 431 that are spaced apart from each other and arranged opposite each other. The root of each elastic buckle arm 431 is connected to the straight rod part 42 respectively. An arc-shaped intermediate connecting part 432 is provided between the two elastic buckle arms 431. The left end and the right end of the intermediate connecting part 432 are connected to the elastic buckle arm 431 on the corresponding side respectively.

[0037] When stacking and clamping sprayed products using the structurally improved stacking spraying fixture device of this embodiment, one sprayed product is clamped between the clamping base plate 1 and the lowest clamping middle plate 3, one sprayed product is clamped between two adjacent clamping middle plates 3, and one sprayed product is clamped between the clamping cover plate 2 and the highest clamping middle plate 3. During this process, the upper end of the middle plate positioning protrusion 31 of the highest clamping middle plate 3 is inserted and connected to the cover plate positioning protrusion 21 to achieve accurate positioning of the highest clamping middle plate 3 and the clamping cover plate 2; the lower end of the middle plate positioning protrusion 31 of the lowest clamping middle plate 3 is inserted and connected to the base plate positioning protrusion 11 to achieve accurate positioning of the lowest clamping middle plate 3 and the clamping base plate 1; the middle plate positioning protrusions 31 of two adjacent clamping middle plates 3 are inserted and connected to achieve accurate positioning of two adjacent clamping middle plates 3. After the clamping cover plate 2, several clamping middle plates 3, and clamping base plate 1 are stacked and clamped to fix the sprayed product, the straight rod part 42 of the locking pin 4 passes through the bottom plate through hole 12 of the clamping base plate 1 and the cover plate through hole 22 of the clamping cover plate 2 from bottom to top. The limiting stop part 41 is located below the clamping base plate 1 and the upper end of the elastic element abuts against the lower surface of the clamping base plate 1. The elastic buckle part 43 is engaged with the cover plate through hole 22 of the clamping cover plate 2. Since the elastic element elastically abuts against the clamping base plate 1 upwards, the clamping base plate 1 and the clamping cover plate 2 can elastically clamp the clamping middle plate 3 and the sprayed product.

[0038] It should be emphasized that during the process of stacking and clamping the sprayed product using the base plate 1, several clamping middle plates 3, and clamping cover plate 2, the middle plate contour positioning pin 32 of each clamping middle plate 3 is inserted into the structural hole of the sprayed product. That is, the clamping middle plate 3 can accurately position the clamped sprayed product through the middle plate contour positioning pin 32. Similarly, the cover plate contour positioning pin 23 of the clamping cover plate 2 is inserted into the structural hole of the sprayed product. That is, the clamping cover plate 2 can accurately position the clamped sprayed product through the cover plate contour positioning pin 23. By positioning the clamped sprayed product through the above-mentioned cover plate contour positioning pin 23 and middle plate contour positioning pin 32, the structurally improved stacked spraying clamping device of this embodiment can effectively ensure the accuracy of the sprayed product clamping.

[0039] It should be further emphasized that, for the intermediate connecting part 432 located between the two elastic buckle arms 431, when the locking pin 4 is in the clamping and locking position, the intermediate connecting part 432 will provide a certain elastic force, which can ensure that each elastic buckle arm 431 is stably kept in the locking position, so as to reduce the risk of the elastic buckle part 43 disengaging.

[0040] In summary, the improved stacking spray clamping device of this embodiment has the advantages of novel structural design, good stability and reliability, and high clamping accuracy.

[0041] Example 2, as Figure 2As shown, the difference between this embodiment 2 and embodiment 1 is that the elastic element is a soft rubber part 5, and the soft rubber part 5 and the locking pin 4 are injection molded into an integral structure.

[0042] The soft plastic part 5 can be a silicone part.

[0043] When the locking pin 4 is in the clamping and locking position, the soft rubber part 5 is in a compressed state. When compressed, the soft rubber part 5 can generate a restoring elastic force on the lower surface of the clamping base plate 1, so that the clamping base plate 1 and the clamping cover plate 2 can elastically clamp the clamping middle plate 3 and the sprayed product.

[0044] Example 3, as Figure 2 and Figure 5 As shown, the difference between this embodiment 3 and embodiment 1 is that each clamping plate 3 has a vertical through hole 33 corresponding to the locking pin 4, and the upper and lower openings of the through hole 33 are respectively flared.

[0045] Regarding the through hole 33 in the middle plate of this embodiment, during the process of inserting or removing the locking pin 4, the through hole 33 in the middle plate designed above can ensure that the elastic buckle part 43 of the locking pin 4 passes smoothly through the through hole 33 in the middle plate.

[0046] Example 4, as Figure 2 and Figure 4 As shown, the difference between this embodiment four and embodiment one is that the lower end opening of the cover plate through hole 22 is flared.

[0047] When the locking pin 4 is inserted, the cover plate through hole 22 of the above-mentioned structural design allows the elastic buckle part 43 of the locking pin 4 to be inserted smoothly.

[0048] Example 5, as Figures 1 to 4 As shown, the difference between this fifth embodiment and the first embodiment is that a lower positioning sleeve 13 protruding downward is provided at the middle position of the lower surface of the clamping base plate 1, and a lower positioning hole 131 is provided in the core of the lower positioning sleeve 13.

[0049] The upper positioning sleeve 24 protruding upward is provided in the middle position of the upper surface of the clamping cover plate 2, and the core of the upper positioning sleeve 24 is provided with an upper positioning hole 241.

[0050] It should be noted that in this embodiment five, the lower positioning sleeve 13 and the upper positioning sleeve 24 are arranged coaxially.

[0051] When multiple sprayed products are stacked and clamped in the improved stack spraying fixture device of this embodiment five, the upper positioning hole 241 and the lower positioning hole 131 can be inserted into the positioning rod on the spraying line. Moreover, the improved stack spraying fixture device of this embodiment five can be placed in both directions, which is convenient to use.

[0052] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
