[0028] It is understandable that, referring to Figures 1 to 6 The utility model provides a door stopper, including a positioning assembly 100 and a magnetic attraction assembly 200. The positioning assembly 100 includes a fixing seat 110, a rotating shaft 120, an abutting block 130 and a screw 140. One end of the rotating shaft 120 is fixedly connected to the fixing seat 110, and the other end of the rotating shaft 120 is inserted into the ground. The fixing seat 110 is provided with a vertical first positioning hole 111. The abutting block 130 is slidably connected to the fixing seat 110. The abutting block 130 is provided with a T-shaped positioning slot 131. and a vertical second positioning hole 132, a screw 140 is sequentially passed through the second positioning hole 132 and the first positioning hole 111 from top to bottom, one end of the screw 140 abuts against the abutment block 130, and the other end of the screw 140 is fixedly connected to the ground to fix the position of the abutment block 130 and the fixing seat 110; the magnetic suction component 200 includes a magnet 210 and two clamping blocks 220, the two clamping blocks 220 clamp the magnet 210, and the two clamping blocks 220 are both embedded in the T-shaped positioning slot 131.

[0029] During assembly, the magnet 210 is clamped by two clamping blocks 220, and the two clamping blocks 220 are both embedded in the T-shaped positioning groove 131, so that the magnet 210 can be fixedly connected to the abutment block 130, and then the abutment block 130 is slidably connected to the fixing seat 110, so as to complete the assembly of the door stopper, which can reduce the difficulty of assembly. When the magnet needs to be replaced, the magnet 210 can be removed by pulling the clamping block 220 out of the T-shaped positioning groove 131, and then removing the clamping blocks 220 on both sides of the magnet 210, so that the magnet 210 can be removed and removed, which can facilitate the disassembly and assembly of the magnet 210. During installation and positioning, one end of the rotating shaft 120 is inserted into the ground so that the fixing seat 110 rotates around the rotating shaft 1 20 is axially rotated, and drives the abutment block 130 to rotate, so as to adjust the angle between the fixing seat 110 and the abutment block 130, so that the abutment surface of the abutment block 130 is parallel to the door surface, so as to increase the abutment area between the abutment block 130 and the door, thereby reducing the collision wear of the door. When adjusted to a preset angle, the screw 140 is passed through the second positioning hole 132 and the first positioning hole 111 from top to bottom in sequence, and the screw 140 is tightened, so that one end of the screw 140 abuts against the abutment block 130, and the other end of the screw 140 is fixedly connected to the ground, which can fix the position and angle of the abutment block 130 and the fixing seat 110, thereby facilitating the installation and positioning of the door stopper.

[0030] In addition, by embedding the position of the positioning clamp block 220 through the T-shaped positioning groove 131, the contact area between the clamp block 220 and the abutment block 130 can be increased while increasing the contact area between the clamp block 220 and the door surface, thereby increasing the force-bearing area to disperse the force and reduce the possibility of deformation of the clamp block 220 due to collision.

[0031] It should be noted that the position of the door is fixed by the magnetic attraction between the magnet 210 and the magnetic suction plate fixedly installed on the door, thereby fixing the opening angle of the door, which can reduce the possibility of the door being accidentally closed due to wind.

[0032] It is understandable that, referring to Figures 3 to 5The fixing seat 110 is provided with a vertical rectangular groove 112 and a circular groove 113. The rectangular groove 112 is connected to the circular groove 113. The diameter of the circular groove 113 is greater than the width of the rectangular groove 112. The abutting block 130 is provided with a first connecting portion 133 and a second connecting portion 134. The first connecting portion 133 is slidably connected to the rectangular groove 112, and the second connecting portion 134 is slidably connected to the circular groove 113. By sliding the first connecting portion 133 from top to bottom to connect to the rectangular groove 112, and at the same time sliding the second connecting portion 134 to connect to the circular groove 113, the installation position of the abutting block 130 can be conveniently positioned by utilizing the matching and limiting of the circular groove 113 and the rectangular groove 112, thereby improving the assembly accuracy and assembly efficiency between the abutting block 130 and the fixing seat 110. In addition, since the rectangular groove 112 is connected to the circular groove 113, the diameter of the circular groove 113 is greater than the width of the rectangular groove 112, and the second connecting portion 134 abuts against the wall of the circular groove 113. The surface can limit the sliding of the abutment block 130 in the horizontal direction away from the fixed seat 110, and the possibility of the abutment block 130 moving with the door due to the magnetic attraction of the magnet 210 is reduced, thereby improving the stability of the installation position of the abutment block 130, and through the second connecting part 134 abutting against the wall of the circular groove 113, the contact area between the abutment block 130 and the fixed seat 110 can be increased, and the force can be dispersed along the circular wall to reduce local stress, thereby reducing the possibility of the abutment block 130 being deformed due to the collision with the door, and the service life of the door stop can be extended.

[0033] Specifically, refer to Figure 2 and Figure 3 , the abutment block 130 is penetrated with a pin shaft 230, and the two clamping blocks 220 are fixedly connected to the abutment block 130 through the pin shaft 230. By embedding the clamping block 220 in the T-shaped positioning groove 131, and then sequentially penetrating the pin shaft 230 in the abutment block 130 and the clamping block, the clamping block 220 can be quickly fixedly connected to the abutment block 130, which facilitates the assembly and fixation between the clamping block 220 and the abutment block 130, and through the limiting of the pin shaft 230, the possibility of the clamping block 220 being separated from the T-shaped positioning groove 131 due to the magnetic attraction of the magnet 210 can be reduced, thereby improving the position stability of the clamping block 220, and further improving the position stability of the magnet 210.

[0034] It should be noted that, refer to Figure 5 and Figure 6 The two opposite side walls of the T-shaped positioning groove 131 are both provided with first through holes 135 , the clamping block 220 is provided with a second through hole 222 , and the pin 230 is passed through the first through hole 135 and the second through hole 222 to fix the clamping block 220 and the abutting block 130 in connection.

[0035] Specifically, refer to Figure 3 and Figure 4, vertical slide grooves 114 are provided on opposite side walls of the rectangular groove 112, and the two ends of the pin shaft 230 are respectively slidably connected to the two slide grooves 114, and the ends of the pin shaft 230 can abut the wall surface of the slide groove 114 to limit the axial movement of the pin shaft 230. When the abutment block 130 is slidably connected to the fixed seat 110, the vertical slide grooves 114 are provided on the opposite side walls of the rectangular groove 112, so that the two ends of the pin shaft 230 can slide into the slide groove 114 in the vertical direction, which is convenient for the installation and positioning of the abutment block 130, and the ends of the pin shaft 230 abut the wall surface of the slide groove 114 to limit the axial movement of the pin shaft 230, which can reduce the possibility of the pin shaft 230 sliding out of the abutment block 130, thereby improving the position stability of the pin shaft 230, and further improving the position stability of the clamping block 220 and the magnet 210.

[0036] It is understandable that, referring to Figure 3 and Figure 6 , a plurality of vertical limiting strips 221 are protruding from one side of the clamping block 220 abutting against the magnet 210, and the plurality of limiting strips 221 are evenly spaced in the horizontal direction. Since a plurality of vertical limiting strips 221 are protruding from one side of the clamping block 220 abutting against the magnet 210, and the plurality of limiting strips 221 are evenly spaced in the horizontal direction, the limiting strips 221 abut against the magnet 210, which can increase the friction resistance of the magnet 210 moving in the horizontal direction, thereby reducing the possibility of the magnet 210 moving with the door due to the magnetic attraction and detaching from the clamping block 220, so as to improve the position stability of the magnet 210.

[0037] It is understandable that, referring to Figures 1 to 3 The positioning assembly 100 further includes a sealing cover 150, which covers the upper opening of the second positioning hole 132. The sealing cover 150 covers the upper opening of the second positioning hole 132, so that the second positioning hole 132 can be sealed, and the possibility of the screw 140 being corroded due to external moisture leaking into the second positioning hole 132 is reduced, thereby improving the anti-corrosion performance of the door stopper and extending its service life.

[0038] It is understandable that, referring to Figure 1 The abutment block 130 is a rubber part. The collision buffering effect of the rubber part can reduce the possibility of damage caused by the door collision due to excessive door opening force, and at the same time, reduce the noise generated by the collision between the abutment block 130 and the door, thereby improving the comfort of use.

[0039] It is understandable that, referring to Figure 1, the fixing seat 110 and the clamping block 220 are both made of stainless steel. Since the fixing seat 110 and the clamping block 220 are both made of stainless steel, the structural strength and anti-corrosion performance of the fixing seat 110 and the clamping block 220 can be improved, and the possibility of deformation of the fixing seat 110 and the clamping block 220 under force can be reduced, thereby extending the service life of the door stopper. In addition, since stainless steel parts have magnetic conductivity, the clamping block 220 can conduct the magnetic force of the magnet 210, thereby improving the magnetic attraction strength and sensitivity.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
