M245322 V. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is a gecko structure, especially a gecko structure that can fix objects on the wall and has a cushioning function. [Previous technology] According to the general gecko structure (that is, expansion bolts) is mainly used to stabilize the object on the wall or the ground, which is mainly composed of a sleeve, a bolt and a cone; A plurality of slotted grooves are cut out at a peripheral edge of one end of the sleeve, and the slotted end of the sleeve is for the tapered block to rest, and the sleeve and the tapered block are accommodated in predetermined holes in the wall or the ground. After inserting the object with bolts, penetrate into the sleeve and form a screw with the tapered block, and squeeze the slotted end of the sleeve through the tapered block to tighten the slotted end of the sleeve. Fastened in the wall 'to achieve the purpose of locking objects. Although 'the conventional gecko structure can lock objects, when an earthquake occurs', the casing, cone and bolt are in a fastened and stiff form. The whole does not have cushioning. Effect, if after a period of shaking, it is easy to drop or break the object, causing a safety concern. · In addition, these gecko structures need to use a conical block to squeeze the casing to make the casing outward. The expansion of the form makes the overall manufacturing cost relatively high, which is not conducive to mass production. Therefore, due to the lack of the conventional gecko structure and the quality requirements in the future market, it is necessary to further improve it. . In view of the gecko structure that is currently used, the author still uses it.

Page 5 M245322 5. Creation instructions (2) Improvements 'so many years of experience in production and lock production of gecko structure-related products', and in view of the current problems of the gecko structure, the method of improvement is considered, and after many improvements and tests After that, a gecko structure was finally created. [New content] For this reason, the main purpose of this creation is to provide a deflection action that can produce shock absorption, ensure that the fixed components will not fall, and have a safe and practical gecko structure. .

Another purpose of this creation is to provide a gecko knot that not only has simple components, which reduces the production cost, but also a simple and convenient overall operation method. In order to achieve the above purpose, this creation proposes a gecko structure. A pipe fitting, a second pipe fitting, an elastic element, and a pressing element with an external thread portion at one end;

A peripheral groove of the first pipe is cut through a slit along its axis, and the first pipe is adjacent to the slit, and at least one uncut slot is provided along its axis, and one end of the first pipe Abutting the second pipe piece, the peripheral edge of the second pipe piece is cut through a slit along its axis, and the position of the second pipe piece adjacent to the slit groove is provided with a plurality of uncut slits along its axis to make the second pipe piece The cut groove of the pipe is separated from the cut groove of the first pipe, and the second pipe is located on the pipe wall of two adjacent cut grooves, respectively, forming a concave portion to the inside of the second pipe to make the first pipe A plurality of inclined flanges are formed inside the pipe, and the elastic element of the second pipe is accommodated, and the external thread of the pressing element is penetrated from the first pipe, and is screwed with the elastic element, so that the elastic element Get

Page 6 M245322 V. Creation instructions (3) Pushing the inclined flange of the second pipe fitting to order the end of the second pipe fitting to form an outwardly expanded shape. Favorable pipe, the following is to make the statement true [Implementation First of all, the tiger structure, the 'the first pipe and the second pipe are provided with a number of grooves on the periphery. In conjunction with the diagram of the preferred embodiment of the present invention, persons familiar with the related technology of the present invention can apply one piece in one piece to further explain the following as follows: 'It is urgent to be the first and the first according to the 2 0 and 4 1 of this specification. One of the pipe fittings is not cut through the second pipe fitting 2 and the groove 21, and the axis is set if the groove 22 and the second pipe fitting 2 open two more pipe fittings 2 inside the second pipe 2 0 and other g. Please refer to The structure of the gecko is that the pipe member 10 of the spring element 40 is adjacent to the slot 1 2 0, and the second and second pipe pieces are not cut through the first pipe piece 1 The first pipe member 1 is composed of elastic elements; the peripheral edge is along the slit 1 ′ and the pipe member 2 2 0 is adjacent to the groove 20 and the adjacent groove is recessed to the edge 2 4 pieces 30 and shown in the wall of this creation. One end of the second pipe has an external threaded portion, and its axis cuts through a slot 1 position. One of the first pipe pieces 10 is located along the axis of the two-phase piece 20, and a plurality of oblique protrusions are provided inside the elastic member 3. Close to the cut groove 2 from the periphery of the first 0, so that the pipe 12 of the groove 12 is a pipe 4 into the pipe 2 (such as the third groove, the pipe 10 is along Its axis 21 is in a position where the second pipe is separated from the wall, divided into 3, so that the figure is shown) and penetrated with the force, 1 1 and the line is set to the end against the cut, a cut, Cut along its 20, and the part forms a second tube, and the first tightening element and the spring

Page 7 M245322 V. Creation instructions (4) The sex element 30 is screwed, so that the elastic element 30 can be pushed against the inclined flange 24 of the second pipe 20, and the end of the second pipe 20 is ordered. The part forms an outward expansion type (as shown in the second figure and the third figure). In this embodiment, the tightening element has various screw types. With the above combination configuration, please continue to refer to the first to third figures. When the user wants to use this creation to fix the bracket 50 on the stepped wall 60, the first pipe 1 〇, the second pipe fitting 2 〇 and the elastic element 30 are placed inside the hole 6 1 of the wall 60, and then the pressing element 40 is passed through the perforation 51 of the bracket 50, and the outer thread portion 4 of the pressing element 40 is pressed. It penetrates from the first pipe fitting 10 and is screwed with the elastic element 30 at one end of the second pipe fitting 20, so that the elastic element 30 can push against the inclined flange 24 inside the second pipe fitting 20, so that the first The ends of the two pipe fittings 20 form an expanded shape and are fastened inside the hole 61 of the wall 60. In this way, the brackets 50 can be set on the wall 60 (as shown in the third circle), and can: (Not shown in the figure) is locked on the bracket 50, the overall assembly is simple because the pipe fittings of this creation are in the form of pipe fittings 20, and the first pipe fitting is provided with a number of cut grooves 1, 2, 2 1 0, and In this way, between the two pipe fittings 20 and 30 and the pressing element 40, the securing or loosening can be ensured, which is safe and practical. The two-stage first pipe fitting i 0 and the second 10 and the second pipe fitting 2 0 have a peripheral edge. Therefore, when an earthquake occurs, the first pipe fitting acts as a cushioning damper, and the elastic element will also produce shock absorption. The deflection action, the objects on the 々 bracket 50 will not fall. In addition, this creation uses the outer threaded part 41 of the pressing element 40 from the first

M245322

A pipe fitting 10 penetrates inside and is screwed with the sexual element 30 at the end of the second pipe fitting 20 so that the elastic element 30 can be pushed against the second pipe fitting 20. The internal flange 2 4 'makes the second pipe fitting The end of 20 is formed into an expanded shape, so that it can be fastened inside the hole 6 1 of Tengbi 60. Not only the components are simple, the production cost is reduced, but the overall operation is simple and convenient. Of course, please refer to the fourth figure, the first pipe fitting and the second pipe fitting 20 of this creation can also be used as a pipe fitting 70, which can also achieve the aforementioned use effect;

… As shown in the figure, the peripheral section of the tube 70 has the effect of cushioning the tube 70. What's new in this article is that this creation does have an excellent effect. You need to apply for a new type of patent in accordance with the law.
