In the prior art, an integrated pressure-maintaining device is usually used for pressure maintenance. The integrated pressure-maintaining device includes a support and a pressure-maintaining head fixedly connected thereto. Due to the limited pressure-maintaining space, the pressure-maintaining head is small in size, and the contact area between the pressure-maintaining head and the support is small, so the connection strength between the pressure-maintaining head and the support cannot be guaranteed. Therefore, during the processing, the support cannot effectively tighten the pressure-maintaining head, and the pressure-maintaining head is easily broken and detached under stress, resulting in the processing quality of the product being affected.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0029] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0030] In the prior art, since mobile phones, watches, electronic bracelets and other products have small hooks, a certain processing step requires the use of a pressure-maintaining head to maintain pressure on the hook. Figure 5 As shown, an integrated pressure-maintaining device is usually used, including a support 1' and a pressure-maintaining head 2' fixedly arranged below the support 1'. The pressure-maintaining head 2' and the support 1' are fixed by bonding or other means. The end of the pressure-maintaining head 2' away from the support 1' abuts against the product to be processed, and the pressure generated by the pressure-maintaining head 2' on the product to be processed is used to maintain pressure and limit the position of the product to be processed. Since the pressure-maintaining space is limited, the size of the pressure-maintaining head 2' is small, and the contact area between the pressure-maintaining head 2' and the support 1' is small, the connection strength between the pressure-maintaining head 2' and the support 1' cannot be guaranteed. Therefore, during the processing, the support 1' cannot effectively tighten the pressure-maintaining head 2', and the pressure-maintaining head 2' is easily broken and detached under force, resulting in the processing quality of the product being affected.

[0031] In order to solve the technical problem in the prior art that the support cannot effectively fasten the pressure maintaining head, and the pressure maintaining head is easily broken and detached under force, resulting in affecting the processing quality of the product, the present application provides a pressure maintaining head reinforcement device, which can effectively fasten the pressure maintaining head in a limited space, and the pressure maintaining head is not easy to break and detach, thereby improving the stability of product pressure maintenance, thereby ensuring the processing quality of the product.

[0032] Figure 1 A three-dimensional diagram of a pressure-maintaining head reinforcement device provided in an embodiment of the present application, Figure 2 for Figure 1 A schematic diagram of the structural explosion of the pressure-maintaining head reinforcement device is shown.

[0033] Figure 1 and Figure 2A pressure-maintaining head reinforcement device provided in an embodiment of the present application includes a support 1, a pressure-maintaining head 2 and a pressure block 3; the support 1 is provided with a first step 11 and a second step 12 connected to each other, and a slot 13 is provided at one end of the support 1 close to the second step 12; the pressure-maintaining head 2 is embedded in the slot 13; the pressure block 3 is arranged on the second step 12 and the pressure block 3 is detachably connected to the support 1, and the orthographic projection of the pressure block 3 on the support 1 at least partially covers the pressure-maintaining head 2, so that a limiting space for the pressure-maintaining head 2 is formed between the pressure block 3 and the slot 13.

[0034] It is worth mentioning that the first step 11 is higher than the second step 12. The pressure block 3 is arranged on the second step 12 to reduce the overall volume of the reinforcement device of the pressure-maintaining head 2 to adapt to the limited pressure-maintaining space. By embedding the pressure-maintaining head 2 in the card slot 13, the pressure block 3 and the card slot 13 together constitute the limiting space of the pressure-maintaining head 2, increasing the force-bearing area of ​​the pressure-maintaining head 2. When the pressure-maintaining head 2 is subjected to shear force, the limiting space plays a role in limiting and fixing the pressure-maintaining head 2. The extrusion force between the pressure block 3 and the pressure-maintaining head 2 can be used to effectively tighten the pressure-maintaining head 2, and the pressure-maintaining head 2 is not easy to fall off and lose, thereby ensuring the processing quality of the product.

[0035] Due to the need to adapt to the product size, the size of the pressure-maintaining head 2 is small, and the pressure-maintaining head 2 is easily worn during the production process, resulting in the need to frequently replace the pressure-maintaining head 2. Through the detachable connection between the pressure block 3 and the support 1, the pressure-maintaining head 2 can be easily removed for replacement, and the installation is convenient.

[0036] In some embodiments, Figure 2 As shown, the slot 13 is U-shaped, and has an opening 131 on one side of the slot 13 facing the pressure block 3, so that the pressure block 3 can abut against the pressure maintaining head 2, and the extrusion force between the pressure block 3 and the pressure maintaining head 2 can be adjusted by adjusting the distance between the pressure block 3 and the slot 13.

[0037] Figure 3 for Figure 1 A front view of the pressure retaining head reinforcement device is shown.

[0038] Furthermore, the side of the pressure-maintaining head 2 facing the opening 131 is higher than the second step 12, and the thickness of the pressure-maintaining head 2 is greater than the depth of the slot 13. Figure 2 and Figure 3 As shown, the length of the pressure-maintaining head 2 in the first direction X is greater than the length of the slot 13 in the first direction X, the length of the pressure-maintaining head 2 in the second direction Y is greater than the length of the slot 13 in the second direction Y, and the first direction X intersects with the second direction Y. After the pressure-maintaining head 2 is embedded in the slot 13, the pressure-maintaining head 2 protrudes toward the side of the opening 131, that is, the side of the pressure-maintaining head 2 facing the opening 131 is slightly higher than the second step 12 in the first direction, and the side of the pressure block 3 facing the pressure-maintaining head 2 is pressed against the pressure-maintaining head 2 to apply a squeezing force to the pressure-maintaining head 2, thereby effectively tightening the pressure-maintaining head 2.

[0039] Furthermore, the depth of the slot 13 is greater than 1 / 2 of the thickness of the pressure maintaining head 2 to ensure the effective contact area between the pressure maintaining head 2 and the base, so that the pressure block 3 and the base can effectively limit the pressure maintaining head 2, thereby improving the reliability of the pressure maintaining head 2.

[0040] In some embodiments, Figure 2 As shown, a limiting hole 31 is provided on the pressing block 3, and a first pin 4 is provided on the limiting hole 31. One end of the first pin 4 passes through the limiting hole 31 and the opening 131 in sequence and abuts against the pressure-maintaining head 2. The first pin 4 can be used to adjust the extrusion force between the pressing block 3 and the support 1 to prevent the pressure-maintaining head 2 from falling off during operation.

[0041] In some embodiments, Figure 2 As shown, a plurality of positioning holes 32 are arranged at intervals on the pressure block 3, and a second pin (not shown in the figure) is arranged on the positioning hole 32, and one end of the second pin passes through the positioning hole 32 and is connected to the support 1. By installing the second pin, the pressure block 3 can be pre-positioned on the support 1, so that the pressure block 3 can be installed quickly and accurately. In this embodiment, the installation sequence of the pressure maintaining head 2 reinforcement device is: first install the pressure maintaining head 2 in the slot 13, then place the pressure block 3 on the second step 12, and then use the second pin to achieve the pre-positioning of the pressure block 3 on the support 1, and the extrusion force between the pressure block 3 and the support 1 can be adjusted by the first pin 4. If the pressure maintaining head 2 is worn and needs to be replaced, the second pin and the first pin 4 are removed in sequence, and then the pressure block 3 is removed, and the pressure maintaining head 2 can be replaced.

[0042] In some embodiments, Figure 2 As shown, the pressing block 3 is provided with a plurality of first threaded holes 33 at intervals, the support 1 is provided with a plurality of second threaded holes 14 corresponding to the first threaded holes 33, and fasteners (not shown in the figure) are provided on the first threaded holes 33 and the second threaded holes 14. The fasteners can be bolts, and by installing the fasteners, the connection stability between the pressing block 3 and the support 1 can be improved, so that the pressure-maintaining head 2 is not easy to fall off from the slot 13.

[0043] Figure 4 for Figure 1 A right side view of the pressure retaining head reinforcement device is shown.

[0044] Alternatively, if Figure 4 As shown, the side of the pressure block 3 facing away from the second step 12 is flush with the first step 11, so as to reduce the overall volume of the reinforcement device of the pressure maintaining head 2.

[0045] In some embodiments, Figure 2 and Figure 3As shown, the support 1 is provided with a first inclined surface 15 at one end away from the first step 11, and the pressing block 3 is provided with a second inclined surface 34 corresponding to the first inclined surface 15 at one end away from the first step 11. By providing the first inclined surface 15 and the second inclined surface 34, space avoidance can be performed to avoid interference with other components in the processing process.

[0046] Furthermore, the angle θ between the first inclined surface 15 and the second inclined surface 34 and the horizontal plane is 30°-60°. The angle can be adjusted according to the actual pressure holding space, but the angle should not be too large to prevent the structural strength of the support 1 from being too low at the turning point. In some embodiments, the angle can be set to 35°, 40°, 45°, 50°, etc.
