Abstract
The utility model discloses a cross slotting hollow rivet which is simple in structure and light in weight. The cross slotting hollow rivet comprises an upper polish rod and a lower polish rod which are coaxial. A boss is arranged between the upper polish rod and the lower polish rod. The boss is provided with a downward through hole in the radial direction of the polish rods, and the center of the upper surface of the upper polish rod is provided with a downward concave hole. The cross slotting hollow rivet is simple in structure, the weight of the cross slotting hollow rivet can be reduced through the concave hole, production materials can be saved, and production cost can be reduced.
Description
Technical field
The utility model relates to a kind of rivet, particularly relates to a kind of cross fluting tubular-shank rivet.
Background technique
Known: the Main Function of rivet is that two links are played to the effect of location.The general socket cap of traditional rivet and light-rod coaxial, therefore in the process of producing because mould and board unbalance stress impact production, manufacturing cost is higher.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the cross fluting tubular-shank rivet of lighter weight.
The utility model solves the technological scheme that its technical problem adopts: cross fluting tubular-shank rivet comprises polished rod, lower polished rod, described upper polished rod and lower light-rod coaxial, between described upper polished rod and lower polished rod, be provided with boss, on described boss, be provided with lower to polished rod through hole radially; Described upper polished rod upper surface central position is to being arranged with shrinkage pool.
Further, the lower surface of described lower polished rod is upwards provided with center hole, and described center hole has internal thread.
Further, described boss is cylindrical.
Further, described boss in the vertical direction be projected as a centrosymmetric image, described centrosymmetric image is by the first circular arc, the first straight line, and the second circular arc, the second straight line, three-arc, the 3rd straight line, the 4th circular arc and the 4th straight line successively head and the tail are connected to form.
The beneficial effects of the utility model: cross fluting tubular-shank rivet described in the utility model, simple in structure.By arrange shrinkage pool can be less the quality of cross fluting tubular-shank rivet, save and produce material simultaneously, reduce production costs.
Accompanying drawing explanation
Fig. 1 is the structure diagram of cross fluting tubular-shank rivet in the utility model embodiment;
Fig. 2 is the plan view of cross fluting tubular-shank rivet in the utility model embodiment;
In figure, indicate: the upper polished rod of 1-, 11-shrinkage pool, 2-boss, 21-through hole, 22-the first circular arc, 23-the first straight line, 24-the second circular arc, 25-the second straight line, 26-three-arc, 27-the 3rd straight line, 28-the 4th circular arc, 29-the 4th straight line, polished rod under 3-, 31-center hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 2, cross fluting tubular-shank rivet comprises polished rod 1, lower polished rod 3, described upper polished rod 1 is coaxial with lower polished rod 3, between described upper polished rod 1 and lower polished rod 3, be provided with and on boss 2, be provided with described in boss 2 down to polished rod 3 through hole 21 radially, described upper polished rod 1 upper surface central position is to being arranged with shrinkage pool 11.
In order to save production material, alleviate rivet quality, described upper polished rod 1 upper surface central position is to being arranged with shrinkage pool 11.By arrange shrinkage pool 11 can be less the quality of cross fluting tubular-shank rivet, save and produce material simultaneously, reduce production costs.
In order to make rivet after riveting part, riveted joint firmly, prevents that rivet from sliding.Wherein a kind of optimal way is, the lower surface of described lower polished rod 3 is upwards provided with center hole 31, and described center hole 31 has internal thread.By center hole 31 is set, in center hole 31 internal tappings.Can be after riveted joint completes again center hole locating piece is installed, thereby fixing rivet and link.
Described boss 2 can have various shape, and described boss 2 is cylindrical, and columniform boss 2 can reduce manufacturing difficulty and save production cost.
The scope using for increasing rivet, a kind of optimal way is wherein, described boss 2 in the vertical directions be projected as a centrosymmetric image, described centrosymmetric image is connected to form by the first circular arc 22, the first straight line 23, the second circular arc 24, the second straight line 25, three-arc 26, the 3rd straight line 27, the 4th circular arc 28 and the 4th straight line 29 successively head and the tail.
Embodiment one:
As shown in Figure 1 and Figure 2, cross fluting tubular-shank rivet, comprises polished rod 1, lower polished rod 3, and described upper polished rod 1 is coaxial with lower polished rod 3, between described upper polished rod 1 and lower polished rod 3, is provided with boss 2, is provided with lower to polished rod 3 through hole 21 radially on described boss 2.Described upper polished rod 1 upper surface central position is to being arranged with shrinkage pool 11.The lower surface of described lower polished rod 3 is upwards provided with center hole 31, and described center hole 31 has internal thread.Described boss 2 in the vertical directions be projected as a centrosymmetric image, described centrosymmetric image is connected to form by the first circular arc 22, the first straight line 23, the second circular arc 24, the second straight line 25, three-arc 26, the 3rd straight line 27, the 4th circular arc 28 and the 4th straight line 29 successively head and the tail.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
