Description

Technical Field

[0001] The utility model relates to a curtain track, in particular to a sealing head of a curtain track with a function of preventing the curtain from rebounding. Background Art

[0002] To prevent the hook from sliding out of the chute when it reaches the end of the curtain track, the traditional method is to set a corresponding sealing head at the end of the curtain track. This sealing head not only plays a role in limiting the hook, but also has a certain aesthetic effect on the curtain track. However, the corresponding structure for restraining the hook is not provided in the sealing head.

[0003] In the actual use of the curtain, due to the elasticity of the curtain fabric itself, a certain amount of curtain rebound often occurs when we close the curtain, and it is necessary to drag the curtain several times to complete the entire closing operation of the curtain, which brings certain inconvenience to the actual use.

[0004] Aiming at the above problems, the utility model designs a sealing head of a curtain track with a function of preventing the curtain from rebounding. A clamping groove for docking with the port of the curtain track is arranged on the sealing head. Once the curtain drives the hook to enter, corresponding clamping and limiting can be realized, thus avoiding the rebound phenomenon when the curtain is closed, and having the characteristics of simple and practical structure.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A sealing head of a curtain track with a function of preventing the curtain from rebounding, including a sealing head body, characterized in that: a plug head inserted into the chute of the curtain track is arranged at the inner end of the sealing head body, a connecting groove docked with the chute of the curtain track is arranged below the plug head, the width inside the connecting groove is greater than the neck width of the curtain hook, a circular arc bulge is arranged at the mouth of the connecting groove, and the width of the mouth of the connecting groove is less than the neck width of the curtain hook.

[0007] More specifically, the width of the mouth of the above-mentioned connecting groove is less than the neck width of the curtain hook in the range of 0.2 - 2 mm

[0008] More specifically, an arc chamfer is arranged at the mouth of the above-mentioned connecting groove.

[0009] More specifically, connecting slopes are arranged on both sides above the mouth of the above-mentioned connecting groove.

[0010] More specifically, a reinforcing rib is arranged below the inside of the above-mentioned connecting groove.

[0011] More specifically, a number of clamping protrusions are arranged around the above-mentioned plug head, and each clamping protrusion is tightly connected with the chute of the curtain track.

[0012] More specifically, a connecting plate is provided above the above-mentioned plug head. A connecting hole is provided on the connecting plate. The plug head is fixedly connected to the top of the sliding groove of the curtain pipe through screws.

[0013] More specifically, a sealing sleeve is sleeved on the outer end of the above-mentioned sealing head body.

[0014] More specifically, a plurality of tongues are provided on the periphery of the inner hole of the above-mentioned sealing sleeve. Corresponding engaging grooves are provided on the outer wall of the sealing head body. After the sealing sleeve and the sealing head body are assembled, the tongues are engaged with the engaging grooves.

[0015] For the sealing head designed by the present utility model, a connecting groove for docking with the sliding groove of the curtain track is provided at its inner end, and an arc-shaped protrusion is provided at the mouth of the connecting groove. The width of the connecting groove is slightly smaller than the width of the neck of the curtain hook. When closing the curtain, once the curtain hook crosses the mouth of the connecting groove under the action of the curtain and enters the inside of the connecting groove, the limit of the curtain hook can be realized, which can effectively avoid the occurrence of the curtain rebounding phenomenon, so that the curtain can be closed with one operation, improving the convenience of closing the curtain to a certain extent, and having the characteristics of simple and practical structure.

[0024] As Figures 1-5As shown in the figure, a curtain track sealing head with a curtain anti-rebound function includes a sealing head body 1. An insertion head 11 that is inserted into the sliding groove of the curtain track is provided at the inner end of the sealing head body 1. A connection groove 111 that is butted against the sliding groove of the curtain track is provided below the insertion head 11. The width of the interior 1111 of the connection groove is greater than the width of the neck 21 of the curtain hook 2. An arc-shaped protrusion 1113 is provided at the mouth of the connection groove 111, and the width of the mouth 1112 of the connection groove is less than the width of the neck 21 of the curtain hook 2. Here, in order to obtain a better clamping and limiting effect, the width of the mouth 1112 of the connection groove is less than the width of the neck 21 of the curtain hook 2 in the range of 0.2 - 2 mm.

[0025] When closing the curtain, once the curtain drives the hook 2 to cross the mouth 1112 of the connection groove and enter the interior 1111 of the connection groove, the limit of the curtain hook 2 can be achieved, thereby avoiding the occurrence of the curtain rebounding phenomenon. It can greatly improve the convenience of closing the curtain and has the characteristics of simple and practical structure.

[0026] Here, in order to improve the smoothness of the hook 2 entering the connection groove 111, an arc chamfer 11121 is provided at the mouth 1112 of the connection groove. At the same time, connection inclined surfaces 11122 can be provided on both sides above the mouth 1112 of the connection groove. The above structure can achieve seamless connection between the connection groove 111 and the curtain track and ensure the smooth movement of the curtain hook 2.

[0027] A reinforcing rib 11111 is provided below the interior 1111 of the connection groove to improve the overall strength of the connection groove 111.

[0028] To achieve effective connection between the insertion head 11 and the curtain track, a number of engaging protrusions 112 are provided around the insertion head 11, and each engaging protrusion 112 is tightly connected to the sliding groove of the curtain track. At the same time, a connecting plate 113 is provided above the insertion head 11, and a connection hole 1131 is provided on the connecting plate 113. During assembly, the connection hole 1131 makes the insertion head 11 fixedly connected to the top of the sliding groove of the curtain track through a screw.

[0029] A sealing sleeve 3 is sleeved on the outer end of the sealing head body 1 to improve the overall aesthetics of the sealing head. A number of locking tongues 31 are provided around the inner hole of the sealing sleeve 3, and a number of engaging grooves 12 are provided on the outer wall of the corresponding sealing head body 1. After the sealing sleeve 3 and the sealing head body 1 are assembled, the locking tongues 31 are engaged and connected with the engaging grooves 12.

[0030] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the invention. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
