Description

Technical Field

[0001] The utility model belongs to the technical field of sealing, in particular to a scraping and brushing rubber strip. Background Art

[0002] The machine tool protective cover is a telescopic protective structure, including a U-shaped cover body that increases proportionally from the inside to the outside. Multiple U-shaped cover bodies are slidably connected to each other. In the unfolded state, they can form a covering protection for the machine tool. However, since sliding must be allowed between the multiple U-shaped covers, there are gaps between adjacent U-shaped covers. The sealing effect is poor after unfolding, and it is easy to leak water and iron filings. At the same time, it is found that the noise generated by friction is relatively large.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Figure 1 A schematic structural diagram of the connection member 100 and the sealing strip 200 in a spliced ​​state is shown; Figure 1 In the embodiment, the scraping rubber strip includes a connecting member 100 and a sealing strip 200 slidably connected to the connecting member 100; the sealing strip 200 can be slidably connected to the connecting member 100 to complete the connection between the connecting member 100 and the sealing strip 200, so that the sealing strip 200 and the connecting member 100 can form a whole before being installed on the cover body, so as to facilitate the subsequent connection with the cover body.

[0019] Figure 2 A schematic diagram of the structure of the connector 100 and the sealing strip 200 in use is shown; in use, the connector 100 can be welded to the upper cover body, and there is a gap between the connector 100 and the lower cover body. After the sealing strip 200 is slidably connected to the connector 100, it is squeezed and deformed by the connector 100 and the lower cover body in the installed state to fill the gap.

[0020] Figure 3 It shows a schematic structural diagram of the connecting member 100 and the sealing strip 200 in a disassembled state; Figure 3In the embodiment, the end of the connector 100 facing the sealing strip 200 has a protrusion 110 and a protrusion 2 120, and the protrusion 110, the protrusion 2 120 and the connector 100 can cooperate to form a dovetail groove 130, and the end surface of the sealing strip 200 facing the connector 100 has a dovetail strip 210 corresponding to the dovetail groove 130. When in use, the dovetail strip 210 is slidably connected to the dovetail groove 130; by forming the dovetail groove 130 on the connector 100, and protruding a dovetail strip 210 corresponding to the dovetail groove 130 on the sealing strip 200, the dovetail strip 210 is slid into the dovetail groove 130 from the front side, and the dovetail groove 130 is formed. The dovetail strip 210 is limited by the shape, so that the connection piece 100 and the sealing strip 200 are connected; the dovetail strip 210 has a concave cavity 211, so that the dovetail strip 210 can allow more deformation when connected to the dovetail groove 130; the connection piece 100 has a concave portion 140, and the connection piece 100 has a convex portion 220 corresponding to the concave portion 140, and the convex portion 220 and the dovetail strip 210 cooperate to form a valley 230, and the valley 230 corresponds to the convex second 120. In the use state, the convex portion 220 fills the concave portion 140 and fills it to form a curved sealing surface, and the convex second 120 squeezes into the valley 230 and forces the valley 230 to be The valley 230 is deformed; in the use state, restricted by the extrusion of the two cover bodies, the protrusion 220 will be squeezed to adapt to the shape of the recessed part 140 after entering the recessed part 140, and the recessed part 140 will be completely filled to form a curved sealing surface, extending the path for water flow to enter and increasing the difficulty of water inlet, and the protrusion 120 will enter the valley 230. Since the space in the valley 230 does not match the shape of the protrusion 120, the valley 230 will be squeezed and deformed to adapt to the shape of the protrusion 120 to form a second line of defense for water flow, and the seam between the recessed part 140 and the protrusion 220 is connected to the seam between the protrusion 120 and the valley 230. The two hoods are connected to each other and form a corrugated structure; in the corrugated structure, the wave crests and wave troughs are strongly squeezed, that is, the squeezing force of the sealing strip 200 toward the connector 100 is increased to enhance the sealing effect; the connector 100 is provided with a step surface 150, and in use, the step surface 150 abuts against the side end of the cover body, and the raised step surface 150 is used to form the positioning of the sealing strip 200 and the cover body when welding, thereby ensuring the installation position of the connector 100 and the sealing strip 200, and in use, there is a gap between the connector 100 and the bottom cover body; the connector 100 is not in contact with the bottom cover body, and the sealing strip 200 is used to space them, thereby effectively reducing noise.

[0021] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
