Description

Technical Field

[0001] The utility model belongs to the technical field of hollow blinds, and in particular relates to a buffer locking structure of an external controller of a hollow blind. Background Art

[0002] Nowadays, hollow blinds have become popular in people's daily lives. External controllers are used in both lifting and flipping operations of blinds. The existing external controller mainly adopts the structure of a slide rail and a sliding handle. In order to limit the sliding handle from sliding out of the slide rail, plugs are generally provided at both ends of the slide rail in the length direction. However, many problems have been found in actual use: First, the sliding handle lacks constraints at the extreme positions at the upper and lower ends of the slide rail (that is, the positions of the plugs). When the operation is completed and the sliding handle is released, it may slide due to the force of the blinds, causing the blinds to slide down (when the blinds are fully retracted) or lift up (when the blinds are fully lowered) when they are fully retracted or fully lowered. Second, the connection between the sliding handle and the slide rail often collides with the plug, and the structure of the connection is often very weak and easy to break after long-term wear. At present, the method of reinforcing the connection is often used to avoid the above situation. However, since the structure of the sliding handle is mostly one-piece, if its structure needs to be changed, it needs to be completed by reopening the mold, which greatly increases the production cost of the external controller.

[0003] In view of the above problems, it is necessary to design a buffer locking structure of the outer operator of the hollow blinds which is simple in structure, low in cost, and can lock the sliding handle at the plug position to prevent the sliding handle from sliding and colliding. To this end, the applicant has ingeniously designed the technical solution. Utility Model Content

[0004] The purpose of the utility model is to provide a buffer locking structure for the external operator of a hollow shutter, which helps to improve the matching structure between the slide rail and the sliding handle to lock the sliding handle in the plug position to avoid displacement of the sliding handle and collision with other parts after the operation is completed, which is beneficial to increase the stability and service life of the external operator and reduce the cost of use.

[0005] The purpose of the utility model is achieved in this way. A buffer locking structure of an external operator of a hollow shutter comprises a slide rail and a sliding handle that slides along the length direction of the slide rail, and anti-slip parts for limiting the sliding handle from sliding out of the slide rail are respectively arranged at the proximal end positions of both ends of the length direction of the slide rail, and its characteristics are: a buffer locking part is respectively arranged at the position between the two anti-slip parts and the sliding handle on the slide rail, and the buffer locking parts are respectively arranged at the position close to the anti-slip parts on the corresponding side, each buffer locking part is clamped on the slide rail and protrudes from one side surface of the slide rail, and when the sliding handle slides to the position of the buffer locking part, the buffer locking part contacts and rubs with one side end of the sliding handle, thereby limiting the collision between the sliding handle and the anti-slip part.

[0006] In a specific embodiment of the utility model, a slide rail cavity is provided on one side of the slide rail along the length direction, the slide rail cavity runs through the length direction of the slide rail, and a slide rail cavity opening is formed on the side of the slide rail cavity facing the sliding handle; when the sliding handle is in use, a sliding block embedded in the slide rail cavity is formed on the side facing the slide rail, and the sliding block extends from the slide rail cavity opening through a connecting plate and is connected to the sliding handle.

[0007] In another specific embodiment of the present invention, the connecting plate, the sliding block and the sliding handle are integrally formed by plastic injection molding.

[0008] In another specific embodiment of the present invention, one end of the anti-slip member is formed with a clamping foot, and the other end is formed with a supporting foot.

[0009] In another specific embodiment of the present invention, the buffer locking member, when in use, has a side facing the slide rail formed with an embedded foot, and a side away from the slide rail formed with an arc-shaped protrusion.

[0010] In another specific embodiment of the present invention, a height h between an outer surface of the arc-shaped protrusion of the buffer locking member and a surface of one side of the slide rail is greater than a gap distance d between the slide handle and the slide rail.

[0011] In a further specific embodiment of the present invention, the buffer locking member is made of rubber.

[0012] In a further specific embodiment of the present invention, the slide rail is a metal part or a plastic part.

[0013] The utility model has the following beneficial effects after adopting the above structure: since the buffer locking member is arranged between the anti-slip member and the sliding handle, when the sliding handle slides to the vicinity of the anti-slip member, the buffer locking member can lock the sliding handle by friction with the sliding handle, and remind the user through the sense of resistance that the sliding handle has slid into place, effectively avoiding the displacement of the sliding handle and collision with other parts after the operation is completed, which is beneficial to improve the stability and service life of the external controller and reduce the cost of use. At the same time, when the blinds are in the two extreme positions of fully retracted or fully lowered, the friction force is increased for the handle to prevent the blinds from sliding down (when the blinds are fully retracted) or lifting up (when the blinds are fully lowered) when the hand is released.

[0020] The specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings, but the description of the embodiments is not a limitation of the technical solution. Any changes in form rather than substance based on the concept of the present invention should be regarded as the protection scope of the present invention.

[0021] In the following description, all concepts related to up, down, left, right, front and back directions or orientations are based on Figure 1 The positions shown are for reference only and thus cannot be understood as a special limitation on the technical solution provided by the present utility model.

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, illustrates a buffer locking structure of an external operator of a hollow blind, comprising a slide rail 1 and a sliding handle 2 sliding along the length direction of the slide rail 1, and anti-slip parts 4 for limiting the sliding handle 2 from sliding out of the slide rail 1 are respectively arranged at the positions near the two ends of the length direction of the aforementioned slide rail 1; as the technical key points of the utility model: the aforementioned slide rail 1 is provided with a buffer locking part 3 at the position between the two anti-slip parts 4 and the sliding handle 2, and the aforementioned buffer locking parts 3 are respectively arranged at the position close to the anti-slip parts 4 on the corresponding side, and each buffer locking part 3 is clamped on the slide rail 1 and protrudes from one side surface of the slide rail 1. When the aforementioned sliding handle 2 slides to the position of the buffer locking part 3, the aforementioned buffer locking part 3 contacts and rubs against one side end of the sliding handle 2, thereby limiting the collision between the aforementioned sliding handle 2 and the anti-slip part 4. The aforementioned buffer locking part 3 is formed with a foot 31 on the side facing the slide rail 1 in the use state, and the side away from the slide rail 1 is formed with an arc-shaped protrusion 32. The height h between the outer surface of the arc-shaped protrusion 32 of the aforementioned buffer locking member 3 and the surface of one side of the slide rail 1 is greater than the gap distance d between the aforementioned sliding handle 2 and the slide rail 1 .

[0023] A slide rail cavity 11 is provided on one side of the slide rail 1 along the length direction. The slide rail cavity 11 runs through the length direction of the slide rail 1. A slide rail cavity opening 12 is formed on the side of the slide rail cavity 11 facing the slide handle 2. When the slide handle 2 is in use, a slider 21 is formed on the side facing the slide rail 1 and is inserted into the slide rail cavity 11 and slides. The slider 21 extends from the slide rail cavity opening 12 through a connecting plate 211 and is connected to the slide handle 2. In this embodiment, the front connecting plate 211, the slider 21 and the slide handle 2 are integrally injection molded by plastic.

[0024] The anti-slip member 4 has a foot 41 at one end and a support foot 42 at the other end. During installation, the foot 41 is first inserted into the slide rail cavity 11 from one end of the slide rail 1, and then the anti-slip member 4 is moved to the anti-slip position of the slide rail 1, and then the anti-slip member 4 is turned over so that the support foot 42 passes through the slide rail cavity opening 12 and supports the bottom of the slide rail cavity 11, thereby completing the fixed installation of the anti-slip member 4.

[0025] The material of the buffer locking member 3 is not limited in any way, and in this embodiment, it is preferably a rubber member. The embedded foot 31 forms an interference fit with the slide rail cavity 11 after passing through the slide rail cavity opening 12 due to its own elasticity.

[0026] Furthermore, the material of the aforementioned slide rail 1 is also not subject to any restrictions, and can be metal, plastic, etc., and is preferably metal in the present embodiment.

[0027] Please continue reading Figures 1 to 4 Combined with Figure 5In actual use, the slide rail 1 is first fixed to the inner glass of the insulating glass blinds, and then the sliding handle 2 is connected to the slide rail 1 through the slider 21 and the sliding handle 2 is connected to the inner controller of the insulating glass blinds, and then the anti-slip part 4 is fixed to the anti-slip position of the slide rail 1, and finally the buffer locking part 3 is clamped on the slide rail 1 through the embedded foot 31. When the sliding handle 2 drives the inner controller to slide to the position close to the corresponding anti-slip part 4, as shown in FIG. Figure 5 As shown, one side of the sliding handle 2 will first contact and rub against the buffer locking member 3 until the sliding handle 2 stops sliding. At this time, the buffer locking member 3 is squeezed and deformed, and the friction force generated will fix the sliding handle 2, thereby effectively preventing the sliding handle 2 from being displaced and colliding with the anti-slip member 4 after the operation is completed, thereby ensuring that the blinds will not slide down or lift up when the blinds are in the two extreme positions of fully retracted or fully lowered.
