Description

One-piece screw head for enhanced tightness

The creation of a screw head with integrated sealing to enhance hermeticity is mainly applied to the technique of enhancing hermeticity with screws.

Press, the traditional conventional screw head, please refer to the first figure: the three-dimensional exploded schematic diagram of the traditional style. The main reason is that: the bottom of the screw head 40 is provided with a horizontal arrangement surface 41, the top of the screw head 40 is provided with a vertically arranged rotating portion 42, the bottom of the horizontal arrangement surface 41 is provided with an outer thread section 43 The horizontal configuration surface 41 is provided with an accommodating groove 44 for accommodating a washer 50 made of a soft material. The center of the washer 50 is provided with a perforation 51. The perforation 51 of the washer 50 is Passing through the outer thread section 43 of the screw 40, the user only needs to sleeve the driving tool on the rotating part 42 to drive the rotating screw 40 to lock into the object 30 (shown in the example of the painted wave board) Until the washer 50 touches the object 30, and the horizontal arrangement surface 41 presses the washer 20 flatly.

However, when the conventional screw head 40 is used in practice, please refer to the second figure: Schematic diagram of the usage state of the conventional type. When the screw head 40 is locked, there is no guarantee that the accommodating groove 44 and the washer 50 are in a horizontal state, and the washer 50 is not offset by rotation, and a gap is likely to occur. At this time, liquid or gas will be arranged horizontally from the screw head 40 Face 41 The outer periphery penetrates inwardly into the inner surface of the object 30, and the sealing effect is poor, which is an existing problem and defect that has yet to be resolved.

The creator is currently engaged in the manufacture and design of related products. He has accumulated many years of practical experience and experience. In response to the existing problems and shortcomings of the above-mentioned traditional screw heads, he has actively invested in the spirit of innovation and improvement, and has completed the integration of enhanced sealing. Formed screw head.

The technical means applied to solve the new problem and the effect compared with the prior art are: the head of the screw head is provided with a rotating part and the bottom of the screw head is provided with an integrally formed reinforced and sealed convex part and concave part, and an external screw is provided below the screw head The outer screw segment is equipped with a washer, which is characterized in that at least one integrally formed convex part and concave part are formed on the outer periphery and the inner periphery of the bottom of the screw head to strengthen the tightness. When the screw head is locked, the pressure is applied to The gasket is elastically deformed, and the convex and concave portions are used to form a wavy continuous sealed area, thereby increasing the sealing performance of the gasket and preventing liquid or gas from penetrating into the object. The sealing effect is good and the efficiency is improved. Its main purpose is achieved By.

In order to make it easy for those who are familiar with this skill to understand the structure of this creation and the functional benefits that can be achieved, a specific embodiment is listed here, and the detailed description is explained in conjunction with the drawings as follows: an integrated seal with enhanced sealing For the screw head, please refer to the third figure: it is a three-dimensional assembly schematic diagram of the first embodiment of the creation. As shown in the fourth figure: It is a three-dimensional exploded and partially enlarged schematic view of the first embodiment of the creation. And the fifth figure shows: It is a sectional schematic diagram of the first embodiment of the creation. Mainly includes: a screw head 10 and a washer 20; wherein: the top of the screw head 10 is provided with a rotating portion 12 in a vertical configuration, the user only needs to sleeve the driving tool on the rotating portion 12 to drive the rotation The screw head 10 is provided with an outer thread section 13 at the center of the bottom of the screw head bottom 11, and is characterized in that: a first flat surface 14 and a first convex portion 15 are provided at the bottom periphery of the screw head bottom 11 The convex portion 15 is immediately provided with a second flat surface 16 and a second convex portion 17, and a first concave portion 18 is provided between the inner periphery of the bottom 11 of the screw head and the outer thread section 13; the washer 20 is made of a soft material, A through hole 21 is provided in the center of the washer 20, and the through hole 21 of the washer 20 is penetrated through a screw with integral sealing and reinforced tightness One of the external thread segments 13 of the head 10.

The original creation combined by the above-mentioned component structures is to provide a screw head with enhanced sealing and integral molding. In practical operation applications: please refer to the sixth figure: it is the use of the first embodiment of the creation State diagram. The user only needs to sleeve the driving tool on the rotating part 12 to drive the rotating screw head 10 to be locked in the object 30 (shown as a painted wave board).

Please refer to the seventh figure: it is a schematic diagram of the locked state during the construction of the first embodiment of this creation. When the outer thread section 13 of the screw head 10 is locked into the object 30 until the washer 20 touches the object 30, the bottom 11 of the screw head is pressed against the washer 20 flatly, so that the outer diameter of the washer 20 expands outward It is an expansion portion 22, and at the same time, the first convex portion 15 of the outer periphery of the screw head bottom 11 and the second convex portion 17 of the inner periphery are engaged downwardly to the surface of the embedded washer 20, and the washer 20 will also elastically deform and expand to fill the first In a recess 18, the construction is completed immediately.

Please refer to the eighth figure: a partially enlarged schematic view of the seventh figure. When liquid or gas penetrates inwards from the outer periphery of the bottom 11 of the screw head, since the screw 10 and the washer 20, the first convex portion 15 of the outer periphery, the second convex portion 17 of the inner periphery, and the first concave portion 18 A wavy continuous sealed area is formed to prevent liquid or gas from continuing to intrude into the inner surface of the object 30, and to enhance the tightness.

For the above-mentioned integrated screw head with enhanced tightness, please refer to the ninth figure: it is a three-dimensional schematic diagram of the second embodiment of this creation. As shown in the tenth figure: It is a three-dimensional exploded and partially enlarged schematic view of the second embodiment of this creation. And as shown in the eleventh and twelfth figures: It is the sectional combination of the second embodiment of this creation and the E-E cross-sectional schematic diagram of the eleventh figure. Wherein, the first convex portion 15 and the second convex portion 17 are discontinuous and discontinuous, and the positions of the first convex portion 15 and the second convex portion 17 are in a staggered state.

Based on the above, the creation of this creation is to provide a screw head with enhanced sealing. After the actual production of the creator and the repeated operation test, it is confirmed that it can indeed achieve the expected functional benefits of the creation, but at the same time is the current It is the first creation in the world that has not yet been heard, and it has industrial use value.
