Technical Field

[0001] The utility model relates to the technical field of door and window screen wire control equipment, in particular to a reel-type door and window screen wire control device. Background Art

[0002] Roll-up door and window screen wire refers to the wire or rope used to roll up and unroll door and window screens. In the roll-up door and window screen system, the screen is usually composed of one or more screen wires, and the screen is rolled up and unrolled by connecting to the reel device. These screen wires are usually made of durable materials, such as nylon, polyester fiber, etc., with good tensile strength and durability. Their diameter and length will be determined according to the size and weight of the doors and windows to ensure the smooth rolling and stable support of the screen. The roll-up door and window screen wire is a key component in the roll-up door and window system. Correct selection and use of screen wires, proper installation and maintenance can ensure the normal operation of the roll-up door and window screen and extend its service life.

[0003] However, in the existing reel-type door and window screen wire control device, the cone wire storage mechanism and the cone connecting rod are an integral whole, and a whole set needs to be replaced. In addition, at the current stage of technology, the cone shield only plays a protective role and has no direct connection with the cone wire storage mechanism, and cannot fix the cone wire storage mechanism after use. At the same time, the wire guide wheel bracket is movable, has a short service life, and is not flexible in operation. Therefore, we propose a reel-type door and window screen wire control device to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a roller-type door and window screen wire control device, which solves the problem that the cone wire storage mechanism and the cone connecting rod are an integral whole, and replacement requires a whole set of replacements. In addition, at the current stage of technology, the cone shield only plays a protective role, has no direct connection with the cone wire storage mechanism, and has no function of fixing the cone wire storage mechanism after use. At the same time, the wire guide wheel bracket is movable, has a short service life, and is inflexible in operation.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a reel-type door and window screen wire control device, including a cone wire storage mechanism, a cone connecting rod is inserted into the inner cavity of the cone wire storage mechanism, and a deep groove ball bearing is fixedly arranged at the top end of the inner cavity of the cone connecting rod;

[0006] A wire guide wheel bracket is arranged outside the cone wire storage mechanism, and a positioning shaft at the bottom of one side of the top end of the wire guide wheel bracket is fixed to the inner cavity of the deep groove ball bearing;

[0007] A wire guide wheel is inserted into the bottom of one side of the wire guide wheel bracket, and a cone shield is arranged on the outer side of the cone wire storage mechanism.

[0008] Preferably, the inner diameter of the cone wire storage mechanism is the same as the outer diameter of the upper middle portion of the cone connecting rod, and the two form an embedded structure.

[0009] Preferably, the center position of the top surface of the cone shield is inserted into the bottom positioning shaft on one side of the top end of the wire guide wheel bracket.

[0010] Preferably, a groove ring is provided on the bottom surface of the cone wire storage mechanism and close to the edge, and a convex ring is provided at the bottom of the cone shield, and the convex ring is inserted into the inner cavity of the groove ring.

[0011] Preferably, the inner diameter width of the groove ring is the same as the thickness of the protrusion ring.

[0012] Beneficial Effects

[0013] The utility model provides a scroll-type door and window screen wire control device. Compared with the prior art, it has the following beneficial effects:

[0014] The reel-type door and window screen wire control device can not only plug and install the cone wire storage mechanism, but also install and fix the deep groove ball bearing through the cone connecting rod. Since the cone wire storage mechanism and the cone connecting rod are detachable, only the cone wire storage mechanism needs to be replaced for later model change, which is convenient for disassembly and saves costs. Since a groove ring is provided on the bottom surface of the cone wire storage mechanism and close to the edge, and a convex ring is provided at the bottom of the cone protective cover, and the convex ring is plugged into the inner cavity of the groove ring, the cone wire storage mechanism and the cone protective cover can be better connected, thereby increasing the working stability and service life of the cone wire storage mechanism. Then, since a wire guide wheel bracket is provided on the outside of the cone wire storage mechanism, and the bottom positioning shaft on one side of the top of the wire guide wheel bracket is fixed to the inner cavity of the deep groove ball bearing, the wire guide wheel bracket is fixed above the cone wire storage mechanism and cannot be moved, which can increase the service life and is easy to operate.

[0022] Through the cone connecting rod 2, the cone wire storage mechanism 1 can be plugged and installed, and the deep groove ball bearing 3 can be installed and fixed, and connected to the gauze reel 8. Since the cone wire storage mechanism 1 and the cone connecting rod 2 are detachable, only the cone wire storage mechanism 1 needs to be replaced in the later stage, which is convenient for disassembly and saves costs. Since a groove ring is provided on the bottom surface of the cone wire storage mechanism 1 and close to the edge, and a convex ring is provided at the bottom of the cone shield 6, and the convex ring is plugged into the inner cavity of the groove ring, the cone wire storage mechanism 1 and the cone shield 6 can be better connected, thereby increasing the working stability and service life of the cone wire storage mechanism 1. Then, since a wire guide wheel bracket 4 is provided on the outside of the cone wire storage mechanism 1, and the bottom positioning shaft on one side of the top of the wire guide wheel bracket 4 is fixed to the inner cavity of the deep groove ball bearing 3, the wire guide wheel bracket 4 is fixed above the cone wire storage mechanism 1 and cannot be moved, which can increase the service life and is easy to operate.

[0025] See also Figure 3 , Figure 4 The inner diameter width of the groove ring is the same as the thickness of the convex ring, which can ensure the stability of the cone shield 6 installed on the cone wire storage mechanism 1.

[0026] During operation, the cone wire storage mechanism 1 can be plugged in and installed, and the deep groove ball bearing 3 can be installed and fixed through the cone connecting rod 2. Since the cone wire storage mechanism 1 and the cone connecting rod 2 are detachable, only the cone wire storage mechanism 1 needs to be replaced in the later stage, which is convenient for disassembly and saves costs. Since a groove ring is provided on the bottom surface of the cone wire storage mechanism 1 and close to the edge, and there is a convex ring at the bottom of the cone shield 6, and the convex ring is plugged into the inner cavity of the groove ring, the cone wire storage mechanism 1 and the cone shield 6 can be better connected, thereby increasing the working stability and service life of the cone wire storage mechanism 1. Then, since a wire guide wheel bracket 4 is provided on the outside of the cone wire storage mechanism 1, and the bottom positioning shaft on one side of the top of the wire guide wheel bracket 4 is fixed to the inner cavity of the deep groove ball bearing 3, at this time, the wire guide wheel bracket 4 is fixed above the cone wire storage mechanism 1 and cannot be moved, which can increase the service life and is easy to operate.

[0027] In summary, the device can facilitate the disassembly and replacement of the cone wire storage mechanism 1, saving costs, and increasing the service life of the cone wire storage mechanism 1.
