Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, a sliding block for a curtain of a roller shutter door comprises a sliding block head 1 and a connecting sheet 2 integrally connected with the sliding block head 1, wherein the sliding block head 1 and the connecting sheet 2 are both made of plastic, a stop hole 3 is required to be formed in the middle of the connecting sheet 2, spring clamping sheets 4 are required to be arranged on the upper surface and the lower surface of the connecting sheet 2, the spring clamping sheets 4 are required to be made of spring steel, the spring clamping sheets 4 on the upper surface and the lower surface of the connecting sheet 2 are required to be arranged into two groups, the two groups of spring clamping sheets 4 are respectively arranged on two sides of the stop hole 3, each spring clamping sheet 4 comprises an attaching portion 41 and a supporting portion 42 which are integrally connected, the supporting portion 42 forms an included angle with the surface of the connecting sheet 2, the included angle is 30 degrees to 45 degrees, wherein caulking grooves 5 are required to be formed on the upper surface and the lower surface of the connecting, an abutting portion 6 is further disposed at an end of the supporting portion 42 away from the attaching portion 41, and a surface of the abutting portion 6 is arc-shaped.
When the sliding block is installed, a mounting hole needs to be punched at the end part of the curtain sheet, then the connecting sheet 2 is inserted into the mounting hole, because the spring clamping sheets 4 are arranged on the upper surface and the lower surface of the connecting sheet 2, the spring clamping sheets 4 comprise the attaching part 41 and the supporting part 42 which are integrally connected, and the supporting part 42 and the surface of the connecting sheet 2 form an included angle, when the connecting sheet 2 is inserted into the mounting hole, due to the extrusion of the inner wall of the mounting hole, the supporting part 42 of the spring clamping sheet 4 can generate elastic deformation and is folded and attached to the connecting sheet 2, so that the connecting sheet 2 can be continuously inserted along the vertical direction of the mounting hole, when the connecting sheet 2 is inserted to the position-stopping hole 3 and aligned with the through hole on the curtain sheet, the force application and propulsion are not continued, the supporting part 42 of the spring clamping sheet 4 can extend and firmly abut against the inner wall of the mounting hole, external force rocks and can't lead to connection piece 2 from the inside roll-off of mounting hole to make the hole of ending 3 align with the through-hole all the time, make things convenient for the insertion of follow-up bolt, make the installation of slider become light simple.
Because the caulking groove 5 has all been seted up on the upper surface and the lower surface of connection piece 2, and laminating portion 41 is flat pastes in caulking groove 5 bottom, then when spring card 4 receives the extrusion and takes place elastic deformation, supporting part 42 can imbed inside the caulking groove 5 rather than protruding in connection piece 2 surface to make the continuation of connection piece 2 insert and become light smooth and easy more.
Because the one end of keeping away from laminating portion 41 at supporting part 42 is provided with conflict portion 6, then when supporting part 42 expandes, conflict portion 6 can firmly support the mounting hole inner wall to predetermined position steadiness has been guaranteed, and because the surface of conflict portion 6 is the arc, so that conflict portion 6 can smoothly slide on the mounting hole inner wall, be difficult for appearing blocking, thereby effectively guaranteed smooth and easy the inserting of connection piece 2.
Since the included angle is 30 to 45 degrees, the inclination angle between the support portion 42 and the surface of the connecting piece 2 is defined to be an acute angle, which not only ensures the free deformation of the support portion 42, but also does not hinder the insertion of the connecting piece 2.
Because spring card 4 adopts the spring steel to make, the spring steel has better elastic deformation ability, and possesses higher tensile strength, elastic limit and fatigue strength, consequently not fragile to still have better intensity when guaranteeing that spring card 4 has high elasticity.
Because the slider head 1 and the connecting piece 2 are both made of plastics, when the slider slides in the guide rail of the roller shutter door, the slider head 1 can be in contact with the inner wall of the guide rail and rub against the inner wall of the guide rail, and when the slider head 1 made of plastics rubs against the inner wall of the guide rail, the noise is low, so that the using effect of the roller shutter door is effectively improved.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
