Please refer to fig. 1, it should be noted that, the auxiliary supporting structure 130 may be a strip-shaped plate structure, one end of the auxiliary supporting structure 130 away from the concave surface, that is, the second end and the end of the side baffle 110 away from the top baffle 120 are located in the same vertical plane, so after the stair strip is installed, the auxiliary supporting structure 130 and the side baffle 110 can both be abutted against the side of the stair step to form a filling area 150, and glue can be filled in the filling area 130, thereby improving the firmness.

In this embodiment, optionally, the top surface of the top baffle 120 includes a connecting plane 121 and a transitional cambered surface 122, where the connecting plane 121 is connected with the outer side surface of the side baffle 110, and one side of the transitional cambered surface 122 away from the connecting plane 121 is inclined to the bottom surface of the top baffle 120. When stair strip 100 cooperates with the step, top baffle 120 cooperates with the plate body on the top surface of step, and transition cambered surface 122 is connected with the plate body on the step top surface, and the protruding structure that the height drop is great is difficult for appearing in the junction of the plate body on top baffle 120 and the step top surface, is difficult for appearing the condition of stumbling the user, and the security is high.

Referring to fig. 2 and 3, in this embodiment, the stair strip 100 may further include a locking assembly 140 for securing the stair strip 100 to the step, the locking assembly 140 being coupled to the top barrier 120.

Optionally, the locking assembly 140 includes a first fixing bar 141, a second fixing bar 142, a locking screw 143, and a key cylinder unit 144. The first fixing bar 141 and the second fixing bar 142 may be of an integral structure, or fixedly connected by a molding or the like. The first fixing strip 141 is used for being attached to the top surface of the step, and the second fixing strip 142 is used for being attached to the front side surface of the step. When assembled, the first fixing strip 141 is fixedly connected with the step by the locking screw 143. For example, a hole can be drilled on the top surface of the stair, a threaded cylinder can be inserted into the hole, the threaded cylinder and the stair can be bonded through glue, then a locking screw 143 passes through the first fixing strip 141 and is screwed into the threaded cylinder, and similarly, the second fixing strip 142 can be connected with the stair through the locking screw 143. Meanwhile, a lock hole is formed in the first fixing strip 141, the lock cylinder unit 144 is connected to the bottom surface of the top baffle 120, and the lock cylinder unit 144 is in plug-in fit with the lock hole so as to limit the top baffle 120 from being far away from the first fixing strip 141. The second fixing strip 142 is provided with a limiting protrusion, and the auxiliary supporting structure 130 is in clamping fit with the limiting protrusion. Meanwhile, the second fixing strip 142 has an outer convex surface that is mated with an inner concave surface.

Further, the lock cylinder unit 144 includes a stem 1441, an elastic member 1442, and a core 1443, the stem 1441 is connected to the bottom surface of the top bezel 120, the core 1443 is slidably connected to the stem 1441 in a direction having an angle with the axis of the stem 1441, for example, the core 1443 is slidably engaged with the stem 1441 in a direction perpendicular to the stem 1441. Specifically, a sliding hole perpendicular to the axis of the stem 1441 is provided on the stem 1441, and the core 1443 is inserted into the sliding hole. The elastic member 1442 is connected to both the stem 1441 and the core 1443, for making the core 1443 have a movement tendency to protrude from the outer circumferential surface of the stem 1441. The elastic member 1442 may be a spring, and the elastic member 1442 is clamped between the stem 1441 and the core 1443. The lock hole comprises a guide hole 1411 and a limiting hole 1412 which are communicated and provided with an included angle, the core column 1441 is inserted into the guide hole 1411, and the core 1443 is inserted into the limiting hole 1412. It should be appreciated that when the core 1443 is inserted into the limiting hole 1412, a portion of the core 1443 is also located in the sliding hole, so that the limitation of the top baffle 120 and the first fixing strip 141 is achieved.

In the actual operation process, the auxiliary supporting structure 130 is clamped with the limiting protrusion, then the stem 1441 is aligned with the guide hole 1411, and the stem 1441 is pressed to be inserted into the guide hole 1411, in this process, the core 1443 can be compressed into the sliding hole after the spring is compressed, so that the core 1443 can also enter into the guide hole 1411. When the core 1443 and the stem 1441 slide together toward the limiting hole 1412, the hole wall of the guide hole 1411 loses the limit on the core 1443 when the core 1443 slides to the position of the limiting hole 1412, and the core 1443 extends out of the sliding hole and enters into the limiting hole 1412 under the action of the elastic member 1442, so that the assembly is completed.

Alternatively, the core 1443 has a guiding slope 1444, and the guiding slope 1444 is configured to abut against a port of the guiding hole 1411 when the stem 1441 is inserted into the guiding hole 1411, so that the core 1443 compresses the elastic member 1442, thereby guiding the core 1443 into the guiding hole 1411.

It should be understood that the number of the cores 1443 may be plural, and each core 1443 is configured with an elastic member 1442, which is correspondingly inserted into one limiting hole 1412, so as to improve the locking force.

It should be noted that, the first fixing strip 141 can be in plug-in fit with the top plate body 002 on the top surface of the floor 001, and the second fixing strip 142 can be in plug-in fit with the side plate body 003 on the front side surface of the floor 001.
