DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1-3 The embodiment of the present application provides a riveting pliers 10 for manually riveting a hanging hole sleeve 30 to a hole position 21 of a clothes-drying rod 20, comprising: two cross-pivoted pliers, an upper die seat 12 connected to the end of one of the pliers, and a lower die seat 14 connected to the end of the other pliers; the upper die seat 12 and the lower die seat 14 are arranged to open and close opposite to each other. In the riveting state, the hanging hole sleeve 30 with a hanging hole 31 is placed between the upper die seat 12 and the lower die seat 14, and the upper die seat 12 and the lower die seat 14 act vertically on the hanging hole sleeve 30, so that the hanging hole sleeve 30 is deformed, thereby realizing that the two ends of the hanging hole sleeve 30 are riveted to the opposite two sides of the clothes-drying rod 20.

[0032] See also Figure 2-5 Further, two cross-pivoted pressing jaws are defined as a left pressing jaw 11 and a right pressing jaw 13, respectively, and the left pressing jaw 11 and the right pressing jaw 13 are pivoted by rivets. The left pressing jaw 11 includes a first hand-held portion 111 and a first bending portion 112, one end of the first bending portion 112 is connected to the first hand-held portion 111, and the other end is vertically connected to the upper die base 12, so that the upper die base 12 can vertically act on one end of the hanging hole sleeve 30. The right pressing jaw 13 includes a second hand-held portion 131 and a second bending portion 132, one end of the second bending portion 132 is connected to the second hand-held portion 131, and the other end is vertically connected to the lower die base 14. Thus, in the riveting state, the first hand-held portion 111 and the second hand-held portion 131 are moved toward each other, so that the upper die seat 12 and the lower die seat 14 are respectively abutted against the two ends of the hanging hole sleeve 30. At this time, the first bending portion 112 and the second bending portion 132 are surrounded to form an avoidance space to avoid touching the upper end or the lower end of the drying rod 20 and causing damage to the drying rod 20. It can be understood that the shape and size of the avoidance space can be designed according to the actual size of the drying rod 20. Specifically, the first bending portion 112 and / or the second bending portion 132 can be U-shaped.

[0033] Further, in some embodiments, the end surface of the upper die base 12 facing the lower die base 14 is a first die pressing surface 123, and the first die pressing surface 123 is provided with a first boss 121 protruding from the plane, which is used to position the hanging hole sleeve 30. The end surface of the lower die base 14 facing the upper die base 12 is a second die pressing surface 143, and the second die pressing surface 143 is provided with an annular guide groove 142, and the guide groove 142 is surrounded to form a second boss 141. In the riveting state, the first molding surface 123 fixes the fixed end 32 of the hanging hole sleeve 30 between the upper mold base 12 and one side of the drying rod 20; the first boss 121 is inserted into the hanging hole 31, and the end of the riveted end 33 of the hanging hole sleeve 30 abuts against the end of the guide groove 142 close to the second boss 141, and then as the first molding surface 123 and the second molding surface 143 gradually approach each other, the end slides along the guide groove 142 for flanging, and finally abuts against the side of the drying rod 20 close to the second molding surface 143, thereby fixing the hanging hole sleeve 30 on the drying rod 20.

[0034] It is understandable that the guide groove 142 can be designed into different shapes as needed to achieve different riveting shapes of the hanging hole sleeve 30. Preferably, the cross-sectional shape of the guide groove 142 can be arc-shaped, which is conducive to the flanging riveting of the riveted end 33 of the hanging hole sleeve 30.

[0035] See also Figure 5-7 In some embodiments, the second boss 141 is recessed in the lower die base 14 relative to the second die pressing surface 143. When the upper die base 12 and the lower die base 14 are closed, the second boss 141 abuts against the first boss 121, so that the stroke of the upper die base 12 and the lower die base 14 can be limited. At this time, the two ends of the hanging hole sleeve 30 abut against the two opposite sides of the air-drying rod 20, that is, the hanging hole sleeve 30 and the air-drying rod 20 are firmly connected. It can be understood that in this state, the first die pressing surface 123 and / or the second die pressing surface 143 are spaced a certain distance from the adjacent air-drying rod side, which can prevent the first die pressing surface 123 or the second die pressing surface 143 from excessively squeezing the surface of the air-drying rod 20 and causing damage to the air-drying rod 20.

[0036] Furthermore, the top surface size of the second boss 141 is smaller than the size of the hanging hole 31, so that it can be inserted into the hanging hole 31, so that the riveted end 33 of the hanging hole sleeve 30 can completely slide along the guide groove 142. In addition, the second boss 141 is configured to be tapered toward the top surface thereof, so that the riveted end 33 of the hanging hole sleeve 30 slides more smoothly along the guide groove 142, and the riveting operation can be more labor-saving.

[0037] Furthermore, the first boss 121 is provided with a chamfer, or the first boss 121 is provided with a cone that is drafted toward its top surface, so that during the riveting process, the middle part of the hanging hole sleeve 30 can have a certain deformation space, and when its riveted end 33 slides and bends along the guide groove 142, the part of the hanging hole sleeve 30 facing the first boss 121 can also be deformed toward the first boss 121, which can resist part of the stress and make the hanging hole sleeve 30 not easy to crack during the riveting process.

[0038] It can be understood that in the present embodiment, the guide groove 142 is a waist-shaped annular groove body adapted to the hanging hole sleeve 30. During the riveting process, the arc-shaped parts at both ends of the hanging hole sleeve 30 in the length direction are subjected to a larger amount of extension deformation during the riveting process and are more prone to cracking. In this case, the chamfer size or draft angle of the first boss 121 corresponding to this part can be increased to reduce the cracking of the riveted end 33.

[0039] It is understandable that in some other embodiments, the guide groove 142 is a waist-shaped annular groove body adapted to the hanging hole sleeve 30, and the width of the guide groove 142 corresponding to the arc portion is greater than the width of other portions. In this way, the riveted end 33 of the hanging hole sleeve 30 has a larger deformation space during the riveting process to resist the stress during the riveting process.

[0040] It is understandable that in some other embodiments, the guide groove 142 is a square annular groove body adapted to the hanging hole sleeve 30, and the width of the guide groove 142 corresponding to the bent portion is greater than the width of other portions. In this way, the riveted end 33 of the hanging hole sleeve 30 has a larger deformation space during the riveting process to resist the stress during the riveting process, thereby reducing the cracking during the riveting process.

[0041] See also Figure 4 In this embodiment, the first molded surface 123 is further provided with a positioning groove 122 adapted to the fixed end 32 of the hanging hole sleeve 30, and the positioning groove 122 is arranged adjacent to the outer wall of the first boss 121. It can be understood that the positioning groove 122 can be set to any shape that is convenient for fixing the fixed end 32 of the hanging hole sleeve 30, and the fixed end 32 is fixed between the upper mold base 12 and the side of the drying rod 20.

[0042] It is understandable that the riveting pliers 10 described in this embodiment are used to perform riveting and pressing on one end of the hanging hole sleeve 30. In some other embodiments, the two ends of the hanging hole sleeve 30 can also be riveted and pressed respectively through the positioning groove 122 and the guide groove 142, which will not be described in detail here.

[0043] Compared with the prior art, the beneficial effects of the embodiments of the present application are: providing a tool for manually installing the hanging hole sleeves of the clothes-drying rod, which can conveniently install the metal hanging hole sleeves so that the metal hanging hole sleeves are firmly riveted to the clothes-drying rod; at the same time, the method of use is simple and safe, which can make it more convenient to repair or replace the hanging hole sleeves during the production process, and is also convenient for users to maintain during daily use.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
