DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0012] Embodiment. An elevator door sill is composed of Figure 1 As shown, it includes a sill bracket 1, wherein a sill body 2 is provided on the upper side of the sill bracket 1, a guide groove 3 is provided on the upper surface of the sill body 2, a detachable protective cover 4 is provided in the guide groove 3, a locking mechanism for fixing the protective cover 4 is provided on one side of the guide groove 3, an elastic lock buckle 17 is provided on the other side of the guide groove 3, the locking mechanism includes two groups of reinforcing plates 5 arranged horizontally and in parallel, a fixing plate 6 perpendicular to the reinforcing plate 5 is provided in the reinforcing plate 5, a spring 7 is provided on the side of the fixing plate 6 opposite to the guide groove 3, a locking block 8 is provided at the end of the spring 7, a guide rod 9 arranged in the spring 7 and passing through the fixing plate 6 is provided at the end of the locking block 8, a matching groove 10 is provided at the end of the guide rod 9, a wedge block 11 for driving the guide rod 9 to move horizontally is provided on the matching groove 10, and the upper end of the wedge block 11 is connected to a clamping strip 13 on the upper end surface of the sill body 2 through a connecting rod 12.

[0013] The reinforcing plate 5 is provided with pressing grooves 14 corresponding to the wedge blocks 11 at the upper and lower ends.

[0014] The guide groove 3 of the sill body 2 is provided with clamping grooves 15 on both sides.

[0015] Both ends of the protective sleeve 4 are provided with clamping blocks 16 corresponding to the clamping slots 15 .

[0016] Principle of the utility model: The present application sets a detachable protective cover 4 in the sill body 2 to better protect the sill body 2. When the protective cover 4 is installed, the card block 16 will cooperate with the card slot 15 to achieve preliminary locking, and further locking is achieved through the elastic lock buckle 17 and the locking mechanism. The reinforcing plate 5 in the locking mechanism can increase the strength of the sill body 2. A fixing plate 6 is arranged between the reinforcing plates 5. The fixing plate 6 is provided with multiple groups of springs 7 symmetrically arranged in the middle of the sill body 2. The spring 7 is provided with a guide rod 9 passing through the fixing plate 6. The ends of the guide rod 9 and the spring 7 are provided with a locking block 8. The locking block 8 is driven by the spring 7 to lock the protective cover 4. At this time, under the action of the spring, the guide rod can support the wedge block to overcome the gravity of the card strip 13. When unlocking, by pressing down the card strip 13, there are connecting rods 12 corresponding to the number of springs 7 under the card strip 13, and there are wedges 11 under the connecting rods 12. During the pressing down of the card strip 13, the wedges 11 cooperate with the matching grooves 10 to move the guide rod 9 away from the guide grooves 3 to achieve unlocking. The elastic lock buckle 17 mainly plays the role of positioning and locking. If the locking effect is to be further improved, locking mechanisms can be set on both sides of the guide grooves 3. The present application has a good protective effect on the sill body 2 through the protective cover 4, and the protective cover 4 is easy to disassemble and assemble.
