[0034] Please refer to Figures 1 to 4 As shown, the present utility model proposes a bottom door seal strip 100 whose width can be adjusted, which is used for the bottom seal of a door body. The bottom door seal strip 100 includes a first colloid 1 and a second colloid 2. The first colloid 1 is provided with a plurality of connecting structures 11; the second colloid 2 is provided with at least one connecting member 21, and each connecting member 21 is detachably connected to a connecting structure 11, so that the first colloid 1 and the second colloid 2 enclose to form a limiting groove 3 for limiting the door body; wherein, the connecting member 21 is detachably connected to different connecting structures 11 to adjust the width of the limiting groove 3. Figure 2 In the x direction is the width direction of the bottom door seal strip 100 and the limiting groove 3.

[0035] In this embodiment, the bottom door seal strip 100 is composed of a first colloid 1 and a second colloid 2. The first colloid 1 is provided with a plurality of connecting structures 11, and the second colloid 2 is provided with at least one connecting member 21. The first colloid 1 and the second colloid 2 form a complete bottom door seal strip 100 through the detachable connection of the connecting structures 11 and the connecting members 21, and the bottom door seal strip 100 encloses to form a limiting groove 3. When the bottom door seal strip 100 is installed at the bottom of the door body, the door body is limited within the limiting groove 3, and at this time, the thickness of the door body corresponds to the width of the limiting groove 3. Therefore, by connecting the connecting member 21 with different connecting structures 11, the width of the limiting groove 3 formed by the enclosure of the first colloid 1 and the second colloid 2 can be changed, so that the width of the limiting groove 3 can be adaptively adjusted according to the thickness of the door body, and the applicable range of the bottom door seal strip 100 can be expanded. During actual use, the user can select the connecting structure 11 connected to the connecting member 21 according to the thickness of the door body, so that the door body can be exactly limited within the limiting groove 3 formed by the enclosure of the first colloid 1 and the second colloid 2, thereby ensuring the installation stability and sealing effect of the bottom door seal strip 100. During actual implementation, there may be a plurality of connecting members 21 on the second colloid 2 to increase the number of connecting members 21 connected to the connecting structures 11 when the first colloid 1 and the second colloid 2 are connected, thereby improving the connection stability between the first colloid 1 and the second colloid 2.

[0036] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the connecting structure 11 is an installation groove 13, and the connecting member 21 is an installation protrusion 22, and the installation protrusion 22 is detachably limited within the installation groove 13.

[0037] In this embodiment, the first colloid 1 and the second colloid 2 are detachably connected through the limiting cooperation of the installation groove 13 and the installation protrusion 22, and the user can adjust the width of the limiting groove 3 formed by the enclosure of the first colloid 1 and the second colloid 2 by replacing the installation groove 13 that cooperates with the installation protrusion 22.

[0038] During actual implementation, the installation groove 13 and the installation protrusion 22 can be detachably connected through interference fit. The installation groove 13 can be recessed on the first colloid 1, and no specific limitation is made here.

[0039] Optionally, a plurality of installation grooves 13 are arranged at intervals along the width direction of the first colloid 1. In this way, by replacing the installation groove 13 that cooperates with the installation protrusion 22, the width of the limiting groove 3 formed by the enclosure of the first colloid 1 and the second colloid 2 can be directly changed; the installation groove 13 is arranged through along the length direction of the first colloid 1. It can be understood that when connecting or disassembling the connecting structure 11 and the connecting member 21, the connecting member 21 can be inserted and pulled out along the length direction of the installation groove 13 from the port of the installation groove 13, so as to complete the connection or disassembly of the first colloid 1 and the second colloid 2.

[0040] In actual implementation, the length of the installation protrusion 22 can match the length of the installation groove 13. The installation groove 13 can penetrate through the first colloid 1 only at one end. When the installation protrusion 22 is inserted into the installation groove 13 from the port of the installation groove 13, the installation protrusion 22 can abut against the side wall of the installation groove 13 at the end far from the port, so as to facilitate the user to judge whether the installation protrusion 22 is installed in place.

[0041] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, the first colloid 1 is provided with a plurality of enclosing members 12, and two adjacent enclosing members 12 enclose to form an installation groove 13.

[0042] In this embodiment, the installation groove 13 is formed by the enclosing members 12 protruding from the first colloid 1. Two adjacent enclosing members 12 and the first colloid 1 enclose to form an installation groove 13. In actual production, the number of installation grooves 13 can be changed by setting different numbers of enclosing members 12 on the first colloid 1, thereby changing the adjustment range of the width of the limiting groove 3. It can be understood that the distance between two adjacent installation grooves 13 is determined by the width of the enclosing member 12 located between these two installation grooves 13, and the distance between two adjacent installation grooves 13 is the minimum adjustment distance of the width of the limiting groove 3. Therefore, the minimum adjustment distance of the width of the limiting groove 3 can be changed by changing the width of the enclosing member 12.

[0043] In actual implementation, the enclosing member 12 and the first colloid 1 are integrally formed. The cross-sectional shape of the installation groove 13 can be set in an inverted L shape, a T shape, a dovetail shape, etc., and no specific limitation is made here. The installation grooves 13 can be arranged on the first colloid 1 at equal intervals. Therefore, when the user adjusts the width of the limiting groove 3, the user can judge the width of the limiting groove 3 formed by the enclosure of the first colloid 1 and the second colloid 2 according to the order of the installation groove 13 that is limitedly matched with the installation protrusion 22 among all the installation grooves 13. Optionally, scales can be marked on the first colloid 1 along the arrangement direction of the installation grooves 13, so as to facilitate the user to accurately adjust the width of the limiting groove 3 according to the thickness of the door body.

[0044] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the enclosing member 12 includes a support section 121 and a first limiting section 122 connected at an angle. One end of the support section 121 is connected to the first colloid 1, and the first limiting section 122 is connected to the other end of the support section 121. The installation protrusion 22 includes a connection section 221 and a second limiting section 222 connected at an angle. One end of the connection section 221 is connected to the second colloid 2, and the second limiting section 222 is connected to the other end of the connection section 221. The connection section 221 penetrates between two adjacent first limiting sections 122, and the second limiting section 222 abuts against the side of the first limiting section 122 close to the support section 121.

[0045] In this embodiment, the enclosing member 12 is composed of a supporting section 121 and a first limiting section 122. The first limiting section 122 is connected to the first colloid 1 through the supporting section 121. The first limiting section 122 is located at one end of the supporting section 121 away from the first colloid 1. Then, the first limiting sections 122 of two adjacent enclosing members 12 enclose to form the notch of the installation groove 13. Correspondingly, the installation protrusion 22 is composed of a connecting section 221 and a second limiting section 222. When the installation protrusion 22 is inserted from the port at one end of the installation groove 13, the connecting member 21 penetrates between the two first limiting sections 122, and the second limiting section 222 is in limiting abutment with the side of the first limiting section 122 close to the supporting section 121, thus realizing the limiting cooperation between the installation protrusion 22 and the installation groove 13.

[0046] In actual implementation, the supporting section 121 and the first limiting section 122 are connected in an inverted T shape, and the connecting section 221 and the second limiting section 222 are connected in a T shape. When the installation protrusion 22 is limited in the installation groove 13, both ends of the second limiting section 222 are mutually limited with the two first limiting sections 122, further improving the stability and reliability of the limiting cooperation between the installation protrusion 22 and the installation groove 13. The cross-sectional area of the second limiting section 222 gradually decreases from the end close to the notch of the installation groove 13 to the end away from the notch of the installation groove 13, so as to reduce the contact area between the second limiting section 222 and the groove wall of the installation groove 13 and reduce the resistance of the installation protrusion 22 inserted into the installation groove 13.

[0047] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the first colloid 1 includes a first installation portion 14 and a first sealing portion 15 arranged at an angle, and the second colloid 2 includes a second installation portion 23 and a second sealing portion 24 arranged at an angle. The first installation portion 14 and the second installation portion 23 are used to connect with the door body, and the first sealing portion 15 and the second sealing portion 24 are used to seal the gap at the bottom of the door body. The first sealing portion 15 is provided with an installation groove 13, the second sealing portion 24 is provided with an installation protrusion 22, and the first installation portion 14, the first sealing portion 15, the second installation portion 23 and the second sealing portion 24 enclose to form a limiting groove 3.

[0048] In this embodiment, the first colloid 1 is composed of the first installation portion 14 and the first sealing portion 15, and the second colloid 2 is composed of the second installation portion 23 and the second sealing portion 24. When the first colloid 1 and the second colloid 2 enclose to form the limiting groove 3, the first installation portion 14 and the second installation portion 23 respectively form the two side groove walls of the limiting groove 3, and the first sealing portion 15 and the second sealing portion 24 form the groove bottom of the limiting groove 3. The first sealing portion 15 is provided with an installation groove 13, and the second sealing portion 24 is provided with an installation protrusion 22. By changing the installation groove 13 that is in limiting cooperation with the installation protrusion 22, the connection position between the first sealing portion 15 and the second sealing portion 24 can be adjusted, and further the width of the limiting groove 3 can be changed.

[0049] In actual implementation, the first sealing portion 15 and the second sealing portion 24 can be overlapped. The installation groove 13 is provided on one side of the first sealing portion 15 close to the second sealing portion 24, and the installation protrusion 22 is provided on one side of the second sealing portion 24 close to the first sealing portion 15. When the first colloid 1 and the second colloid 2 are connected, the first sealing portion 15 and the second sealing portion 24 are at least partially overlapped. By changing the installation groove 13 that is in limiting cooperation with the installation protrusion 22, the width of the overlapping part of the first sealing portion 15 and the second sealing portion 24 can be changed, and further the width of the limiting groove 3 can be changed.

[0050] It can be understood that when the bottom door seal strip 100 is installed on the door body, the first installation portion 14 and the second installation portion 23 are respectively connected to the door surfaces on both sides of the bottom of the door. The first sealing portion 15 and the second sealing portion 24 are located between the bottom of the door and the ground to seal the door gap at the bottom of the door. The first installation portion 14 can be elastically connected to the first sealing portion 15, and the second installation portion 23 can be elastically connected to the second sealing portion 24. In the normal state, the first installation portion 14 and the second installation portion 23 are bent towards the limiting groove 3 to reduce the space occupied by the bottom door seal strip 100 and facilitate the storage of the bottom door seal strip 100. When the bottom door seal strip 100 is installed on the door body, the first installation portion 14 and the second installation portion 23 are limited by the door body and respectively move relative to the first sealing portion 15 and the second sealing portion 24. That is to say, the first colloid 1 and the second colloid 2 undergo elastic deformation. Under the action of the elastic force, the first installation portion 14 and the second installation portion 23 will tightly press against the two side door surfaces of the door body towards the limiting groove 3. Under the action of static friction, the bottom door seal strip 100 can be installed on the door body without falling off.

[0051] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the first installation portion 14 is provided with a first surface and a second surface facing away from each other. The first surface is used for connecting with the door body, and the second surface is provided with a first raised stripe 17; and / or, the second installation portion 23 is provided with a third surface and a fourth surface facing away from each other. The third surface is used for connecting with the door body, and the fourth surface is provided with a second raised stripe 26.

[0052] In this embodiment, when the bottom door seal strip 100 is installed on the door body, the first surface of the first installation portion 14 and the third surface of the second installation portion 23 are closely attached to the door surface of the door body. The second surface of the first installation portion 14 and the fourth surface of the second installation portion 23 are opposite to the door surface of the door body. The second surface and the fourth surface are respectively provided with a first raised stripe 17 and a second raised stripe 26 to increase the friction resistance coefficient of the second surface and the fourth surface, reduce the difficulty for the user to hold the bottom door seal strip 100, and facilitate the user to install the bottom door seal strip 100.

[0053] In actual implementation, the convex stripes extend along the extending direction of the bottom door seal strip 100. The first mounting portion 14 and the second mounting portion 23 may also be provided with concave stripes, which are not specifically defined herein.

[0054] In an embodiment of the present utility model, as Figures 1 to 4 shown, the first colloid 1 further includes a first bending portion 16. The first mounting portion 14 and the first sealing portion 15 are connected through the first bending portion 16, and the first bending portion 16 is made of an elastic material; and / or, the second colloid 2 further includes a second bending portion 25. The second mounting portion 23 and the second sealing portion 24 are connected through the second bending portion 25, and the second bending portion 25 is made of an elastic material.

[0055] In this embodiment, the first mounting portion 14 and the first sealing portion 15 are elastically connected through the first bending portion 16. The first mounting portion 14 and the first sealing portion 15 are arranged at an angle. The second mounting portion 23 and the second sealing portion 24 are elastically connected through the second bending portion 25. The second mounting portion 23 and the second sealing portion 24 are arranged at an angle. When the bottom door seal strip 100 is not in use, under the action of the first bending portion 16, the first mounting portion 14 and the first sealing portion 15 are in a folded state. Under the action of the second bending portion 25, the second mounting portion 23 and the second sealing portion 24 are in a folded state, so as to facilitate the storage of the bottom door seal strip 100. When the bottom door seal strip 100 is installed on the door body, the first mounting portion 14 and the second mounting portion 23 are pressed by the door body, and the first bending portion 16 and the second bending portion 25 are deformed, so that the first mounting portion 14 and the second mounting portion 23 clamp the door body, thereby ensuring the stability of the installation of the bottom door seal strip 100.

[0056] In actual implementation, the first mounting portion 14, the first sealing portion 15 and the first bending portion 16 may be integrally formed. The second mounting portion 23, the second sealing portion 24 and the second bending portion 25 may be integrally provided. The material of the first colloid 1 may be rubber or plastic material, which is not specifically defined herein. In actual implementation, in order to further ensure the installation stability of the bottom door seal strip 100, the first mounting portion 14 and the second mounting portion 23 may also be bonded to the door body, which is not specifically defined herein.

[0057] In an embodiment of the present utility model, as Figure 2 and Figure 4 shown, the second colloid 2 is further provided with a soft brush 27. The soft brush 27 is arranged on the side of the second colloid 2 facing away from the connecting member 21 and is used for contacting the ground.

[0058] In this embodiment, a soft brush 27 is further provided on the side of the second colloid 2 facing away from the connecting member 21. When the bottom door seal strip 100 is installed on the door body, the soft brush 27 contacts the ground. The provision of the soft brush 27 not only ensures the sealing effect at the bottom of the door body, but also reduces the friction with the ground when opening or closing the door, facilitating the user to open or close the door. It can be understood that the soft brush 27 extends along the extending direction of the bottom door seal strip 100. When the door body is opened or closed, the end of the soft brush 27 in contact with the ground will bend and deform in the opposite direction of the moving direction of the door body, so as to reduce the resistance between the bottom door seal strip 100 and the ground when the door body moves.

[0059] In actual implementation, the material of the soft brush 27 is rubber or nylon, etc., and no specific limitation is made here. The soft brush 27 can be detachably connected to the second colloid 2. When the soft brush 27 is worn to a certain extent, the soft brush 27 can be replaced.

[0060] In an embodiment of the present utility model, as Figure 1 shown, the connecting structure 11 is a female buckle, and the connecting member 21 is a male buckle; and / or, the connecting structure 11 and the connecting member 21 are Velcro.

[0061] In this embodiment, the connecting structure 11 and the connecting member 21 can be a male-female buckle, and the connecting member 21 and the connecting structure 11 are connected by buckling, or, the connecting structure 11 and the connecting member 21 are Velcro, and the connecting member 21 and the connecting structure 11 are connected by adhesion, and no specific limitation is made here.

[0062] In actual implementation, there are multiple female buckles, and the multiple female buckles are arranged at intervals on the first colloid 1, and the male buckle is arranged on the second colloid 2.
