(10) Furthermore, adhesive tape is attached to one side of the adhesive plate 10, and is covered with a release sheet, such that upon on-site installation, when a user removes the release sheet, the adhesive surface 12 is exposed.

(11) Moreover, the gap-maintaining piece 20 according to the present invention protrudes on the other side of the adhesive plate 10 to locally support an edge area of the fixing bracket 1a and to support a gap between the adhesive plate 10 and the fixing bracket 1a.

(12) The gap-maintaining piece 20 is formed to have the same shape as the outer appearance of the fixing bracket 1a of the door stopper 1, as illustrated in FIG. 1.

(13) Additionally, the gap-maintaining piece 20 creates a gap between the adhesive plate 10 and the fixing bracket 1a, and a fastening pipe 40, which will be described later, protrudes by the distance of the gap to ensure a space for fastening a bolt 42.

(14) Furthermore, the inner compartment 30 according to the present invention forms an isolation section between the adhesive plate 10 and the fixing bracket 1a by the gap-maintaining piece 20.

(15) The inner compartment 30 serves as a space where the adhesive plate 10 and the fixing bracket 1a are spaced apart from each other without contact, and forms an isolated section along with the gap-maintaining piece 20, to provide a space capable of buffering the impact applied from the door stopper 1, together with the buffer pad 60.

(16) That is, by the inner compartment 30, the edge area of the fixing bracket 1a is in local contact with the gap-maintaining piece 20 to locally compress the buffer pad 60, thereby improving buffering efficiency.

(17) Additionally, the fastening pipe 40 according to the present invention protrudes on the adhesive plate 10 corresponding to the inner compartment 30, and is screw-coupled with a bolt 42 inserted through a mounting hole H of the fixing bracket 1a.

(20) The temporary assembly module 50 includes: a quadrangular hole 52 formed in the fixing bracket 1a; and a pair of elastic pieces 54 protruding on the adhesive plate 10 corresponding to the quadrangular hole 52 to be fit-coupled to both sides of the quadrangular hole 52.

(21) In this instance, since the width of the pair of elastic pieces 54 is larger than the width of the quadrangular hole 52, when the elastic pieces are fit-coupled, the elastic pieces 54 are deformed elastically and is forcedly fit to the quadrangular hole 52.

(22) As described above, the fixing bracket 1a is temporarily assembled to match the gap-maintaining piece 20 by the fit-coupling of the elastic pieces 54 and the quadrangular hole 52.

(23) In this instance, the elastic pieces 54 are arranged vertically, and each has a side with width smaller than the vertical width of the quadrangular hole 52 and has a retaining portion 56 protruding on the top thereof in the vertical direction.

(24) As illustrated in FIGS. 3(a)-3(b), when the fixing bracket 1a is moved downward in the state in which the elastic pieces 54 are inserted into the quadrangular hole 52, the retaining portion 56 is engaged with the rear side of the fixing bracket 1a to enhance the fastening force between the fixing bracket 1a and the adhesive plate 10, thereby preventing movement and separation of the fixing bracket 1a even when a high load is applied to the door stopper 1.

(25) In FIG. 4, the elastic pieces 54 are arranged vertically, and the retaining portion 57 is provided between the elastic pieces 54 in the horizontal direction.

(26) The retaining portion 57 is inserted into the quadrangular hole 52 and engaged with the rear side of the fixing bracket 1a, such that the fixing bracket 1a and the adhesive plate 10 are temporarily assembled by the temporary assembly module 50, and then, are fastened by the retaining portion 57 to be fixed in position.

(27) Accordingly, during the installation of the door stopper 1 on the door, since the movement of the fixing bracket 1a is prevented, anyone can easily construct the door stopper in correct position.

(28) In addition, the buffer pad 60 according to the present invention is installed on one side of the fixing bracket 1a to be grounded to the gap-maintaining piece 20 and the fastening pipe 40.

(29) The buffer pad 60 is formed of rubber material, and has the same shape as the fixing bracket 1a.

(30) Furthermore, the buffer pad 60 is positioned between the fixing bracket 1a and the gap-maintaining piece 20 to flexibly absorb repetitive impact loads generated during the folding operation of the door stopper 1, thereby effectively preventing loosening of the bolt 42.

(31) In FIG. 2, the inside of the inner compartment 30 is divided into a plurality of spaces by partition plates 32, which are provided to connect the gap-maintaining piece 20 and the fastening pipe 40.

(32) The gap-maintaining piece 20 and the fastening pipe 40 are interdependently reinforced by the partition plates 32, thereby enhancing durability.
