Description

Technical Field

[0001] The utility model relates to a metal mesh braiding tension frame. Background Art

[0002] With the increasing integration of circuits, the high frequency and high speed of electronic devices, and the miniaturization of integrated circuits, the heat generated per unit volume of electronic components and the energy consumption of individual chips have increased. To address this, existing technologies have developed heat dissipation devices for electronic components. A heat dissipation device is a device that transfers heat from a point heat source to a large area for heat dissipation. It utilizes the phase change and flow heat transfer of the working fluid within the cavity to diffuse the heat energy to the condensation end to dissipate the heat. A capillary structure then guides the internal working fluid back to the heat source, thereby achieving rapid heat conduction and heat diffusion.

[0003] Among them, the capillary structure of the heat spreader generally adopts a copper metal mesh, and the metal mesh is formed into a mesh structure through a weaving process. In the process of weaving the metal mesh, it is necessary to maintain a certain tension on the metal wire to ensure that a preset tension is formed between the metal wires of the woven metal mesh, thereby ensuring the heat exchange efficiency and stability of the heat spreader. The general tensioner for the wire is driven by a spring to move the upper clamp downward to the lower clamp. The wire passes between the upper and lower clamps to adjust the tension of the wire. In order to guide the wire to enter and leave the tensioner in a preset direction, a wire sleeve is also required. However, when weaving wires of different diameters, the wire sleeve must also be replaced to adapt to the diameter of the wire. When replacing the wire sleeve, its height position also needs to be calibrated, which makes production very inconvenient.

[0004] In addition, after being used for a period of time, the elastic force of the spring member declines, resulting in a decrease in the clamping force between the upper clamping piece and the lower clamping piece, which is not conducive to maintaining the stability of the tension of the wire.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0031] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] See also Figures 1 to 3 The utility model relates to a metal mesh weaving tension frame, comprising: a bracket body 100, the bracket body 100 is provided with a vertical guide rod 200, the vertical guide rod 200 is penetrated by an upper splint 300 and a lower splint 400, the lower splint 400 is fixed relative to the vertical guide rod 200, the upper splint 300 is connected to a downward driving mechanism 500 that drives it close to the lower splint 400 to clamp the metal wire, the vertical guide rod 200 is radially penetrated by a wire passage 210, the wire passage 210 connects the gap between the upper splint 300 and the lower splint 400, the bracket body 100 is respectively provided with a sleeve assembly 600 for guiding the traction direction of the metal wire at both ends corresponding to the wire passage 210, and the sleeve assembly 600 is provided with an adjustment mechanism that can adjust the aperture size of its internal channel.

[0033] The metal mesh weaving tension frame of the above structure passes the metal wire through the two sleeve assemblies 600, the wire channel 210, and between the upper clamping plate 300 and the lower clamping plate 400. Since the downward driving mechanism 500 drives the upper clamping plate 300 and the lower clamping plate 400 to clamp the metal wire, the metal wire reaches a certain tension to meet the requirements of metal mesh weaving. The adjustment mechanism can adjust the aperture size of the internal channel of the sleeve assembly 600 to meet the needs of metal wires of different diameters, so it is suitable for guiding metal wires of different diameters through the sleeve assembly 600, and can obtain good lead-in effects when dealing with metal wires of different diameters.

[0034] See also Figure 3 and Figure 6In some embodiments of the present invention, the sleeve assembly 600 includes an inner sleeve 610 and an outer sleeve 620 sleeved on the outside of the inner sleeve 610, the inner sleeve 610 has at least two through holes 611 distributed around its axis circumference along the radial direction of the inner sleeve 610, the adjustment mechanism includes a plurality of moving blocks 710 respectively slidingly arranged in the through holes 611 along the radial direction of the inner sleeve 610, the end of the moving block 710 extending into the inner sleeve 610 has an arc concave surface 711, the end of the moving block 710 extending from the inner sleeve 610 is provided with a first driving inclined surface 712 extending along the length direction of the inner sleeve 610, the outer sleeve 620 is provided with a second driving inclined surface 621 that can maintain contact with the first driving inclined surface 712, and the outer sleeve 620 can feed relative to the inner sleeve 610 to adjust the distance between all the arc concave surfaces 711. It is understood that during the feeding movement of the outer sleeve 620 relative to the inner sleeve 610, the second driving bevel 621 moves along the slope of the first driving bevel 712, thereby driving the moving block 710 to move inward along the through hole 611 or allowing the moving block 710 to move outward along the through hole 611. Specifically, when the second driving bevel 621 contacts the low-slope position of the first driving bevel 712, the distance that the moving block 710 extends into the inner sleeve 610 is shorter, the distance between the arc concave surfaces 711 is longer, and the diameter of the metal wire allowed to pass through all the arc concave surfaces 711 is larger. When the second driving bevel 621 contacts the high-slope position of the first driving bevel 712, the distance that the moving block 710 extends into the inner sleeve 610 is longer, the distance between the arc concave surfaces 711 is closer, and the diameter of the metal wire allowed to pass through all the arc concave surfaces 711 is smaller, thereby achieving adjustment of the aperture size of the internal channel of the sleeve assembly 600.

[0035] See also Figure 6 In some embodiments of the present invention, three through holes 611 and three moving blocks 710 are provided. A guide channel 720 for the metal wire to pass through is defined between all the arcuate concave surfaces 711. The central angle of the arcuate concave surfaces 711 is greater than 60°, which helps the guide channel 720 formed by all the arcuate concave surfaces 711 to be closer to a circle, thereby better guiding the metal wire through the guide channel 720. Of course, in other embodiments, the number of through holes 611 and moving blocks 710 can be increased to four, five, etc.

[0036] In some embodiments of the present invention, the movable block 710 and the outer sleeve 620 are both made of magnetic materials, and the outer sleeve 620 and the movable block 710 can attract each other to maintain contact between the first driving inclined surface 712 and the second driving inclined surface 621. It is understood that the attraction of the outer sleeve 620 to the movable block 710 can ensure the stability of the guide channel 720 and prevent the movable block 710 from automatically moving inward and crushing the metal wire.

[0037] See also Figure 4 In some embodiments of the present invention, the movable block 710 is provided with a side protrusion 730 on one side of the first driving inclined surface 712. A first elastic member 740 is provided between the side protrusion 730 and the outer peripheral wall of the inner sleeve 610 to drive the movable block 710 to extend radially outward from the inner sleeve 610, thereby maintaining contact between the first driving inclined surface 712 and the second driving inclined surface 621. The use of the first elastic member 740 is simpler and less costly than the aforementioned magnetic attraction method.

[0038] See also Figure 2 、 Figure 3 and Figure 6 In some embodiments of the present invention, the outer circumferential wall of the inner sleeve 610 is provided with an external thread pointing to the lower slope of the first driving inclined surface 712, the inner circumferential wall of the outer sleeve 620 is provided with an internal thread matching the external thread, and the second driving inclined surface 621 is a frustum arranged around the axial circumference of the outer sleeve 620, and the frustum can contact each of the first driving inclined surfaces 712. The above structure achieves a precise feeding effect of the outer sleeve 620 relative to the inner sleeve 610. When the outer sleeve 620 rotates, the frustum can move upward along the slope of the first driving inclined surface 712, thereby driving all the moving blocks 710 to move radially inward.

[0039] See also Figure 5 In some embodiments of the present invention, the adjustment mechanism includes a plurality of stacked plates 750, which are pivotally connected to the ends of the sleeve assembly 600. Each plate 750 is provided with a positioning hole 751 symmetrically about the pivot center. A guide hole 752 is provided in the middle of each plate 750, and the diameters of the guide holes 752 of each plate 750 increase sequentially. The end surface of the sleeve assembly 600 is telescopically provided with a ball structure 760 capable of engaging with any of the positioning holes 751. In this embodiment, the aperture size of the internal passage of the sleeve assembly 600 can be adjusted by aligning one of the plates 750 with the axis of the sleeve assembly 600. The ball structure 760 and the positioning hole 751 combine to prevent the plate 750 from relative displacement.

[0040] See also Figure 1 and Figure 2 In some embodiments of the present invention, the downward pressure drive mechanism 500 includes a weight member disposed through the vertical guide rod 200. The weight member directly or indirectly applies pressure to the upper clamping plate 300, thereby driving the upper clamping plate 300 and the lower clamping plate 400 to jointly clamp the wire passing through the wire passage 210. It is understood that the user can select different types of weight members based on the desired pressure applied to the wire. This method of applying pressure is more stable and will not change due to changes in the elastic coefficient.

[0041] See also Figure 2 In some embodiments of the present invention, in order to better transmit pressure to the upper splint 300, the vertical guide rod 200 is penetrated by a compression spring 800, and a lifting block 900 is slidingly provided on the vertical guide rod 200 to abut against the upper end of the compression spring 800. The upper part of the vertical guide rod 200 is provided with an anti-slip portion 220 corresponding to the lifting block 900, and the middle part of the weight member is provided with a makeshift hole for the anti-slip portion 220 and the vertical guide rod 200 to pass through.

[0042] In some embodiments of the present invention, in order to make the force applied by the downward driving mechanism 500 to the upper clamping plate 300 more uniform, the weight piece is in a circular ring shape, and the compression spring 800 is in a tower shape that is narrow at the top and wide at the bottom.

[0043] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
