Description

Technical Field

[0001] The utility model relates to the technical field of belt-shaped body retracting and releasing, in particular to a warning tape retracting and releasing device. Background Art

[0002] The existing warning tape retracting device consists of a shell and a winding roller arranged in the shell, wherein the shell is provided with an outlet, one end of the warning tape is wound on the winding roller, and the other end extends from the outlet to the outside of the shell. When the warning tape needs to be used, the warning tape is pulled by hand to be pulled out from the outlet; when it is taken back after use, the winding roller is turned by hand to wind the warning tape around the winding roller. When the warning tape is pulled out, the friction between the warning tape and the outlet edge of the retracting device is too large, which causes the warning tape to get stuck easily when it is pulled out, affecting its use. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the existing warning tape retracting device is easy to get stuck when the warning tape is pulled out. The utility model provides a warning tape retracting device, by adding two tape guide rollers at the outlet, so that when the warning tape is pulled out, it passes through the gap between the two tape guide rollers and contacts the circumferential surface of the tape guide rollers, which can reduce the friction between the warning tape and the outlet, thereby avoiding the problem of getting stuck.

[0004] In order to solve the above technical problems, the embodiment of the utility model discloses a warning tape retracting and releasing device, the warning tape has a first end and a second end, and the retracting and releasing device comprises:

[0005] The outer shell is a cylinder, and a receiving space is provided inside the outer shell;

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the utility model discloses a warning tape retracting device, wherein the warning tape 12 has a first end and a second end, and the retracting device comprises: a housing 1, a winding roller 2, an outlet 3 and a tape guide roller 4. Among them, the housing 1 is a cylinder, and a accommodating space is provided in the housing 1. The winding roller 2 is provided in the accommodating space. The axis of the winding roller 2 coincides with the axis of the cylinder, and the winding roller 2 can rotate around its own axis. The first end of the warning tape 12 is wound on the winding roller 2, and the second end of the warning tape 12 is a free end. Exemplarily, the housing 1 is made of nylon material, which is not only wear-resistant but also low in cost. A fixed shaft is also provided in the accommodating space, and the winding roller 2 is sleeved on the fixed shaft. The outlet 3 is provided on the circumferential surface of the housing 1, and the outlet 3 is connected to the accommodating space. The second end of the warning tape 12 can be pulled out from the outlet 3. The two guide rollers 4 are rotatably disposed in the accommodation space and close to the outlet 3. A first gap 13 is formed between the two guide rollers 4. The second end of the warning tape 12 passes through the first gap 13 and the outlet 3 in sequence and extends to the outside of the housing 1 (such as Figure 3 shown).

[0034] By adopting the above technical solution, two rotatable tape guide rollers 4 are arranged near the outlet 3, and the warning tape 12 is passed through the first gap between the two tape guide rollers 4, so that the warning tape 12 can contact the circumferential surface of the tape guide roller 4. When the warning tape 12 is pulled out from the outlet 3, the tape guide roller 4 can rotate around its own axis under the friction of the warning tape 12, thereby reducing the friction force of pulling out the warning tape 12, avoiding jamming, and improving the convenience of use.

[0035] Optionally, a spring is further included, which is arranged between the fixed shaft and the winding roller 2. When the second end of the warning tape 12 is pulled out from the outlet 3 by an external force, the spring is retracted and stores energy; when the warning tape 12 is not subjected to an external force, the spring is extended and releases energy, thereby driving the winding roller 2 to rotate, so that the warning tape 12 is wound around the winding roller 2. By providing a spring, the winding roller 2 can be driven to rotate automatically, so that the warning tape 12 is automatically wound around the winding roller 2, thereby saving manpower and improving use efficiency.

[0036] Alternatively, if Figure 2 and Figure 3 As shown, the housing 1 further includes a guide plate 5, which is arranged in the accommodating space along the circumference of the winding roller 2. Specifically, the guide plate 5 is an arc-shaped plate, and the axis of the arc-shaped plate coincides with the axis of the winding roller 2. A second gap 14 is provided between the guide plate 5 and the inner wall of the housing 1. After the second end of the warning tape 12 passes through the second gap 14, it extends from the outlet 3 to the outside of the housing 1. By providing the guide plate 5, the warning tape 12 can be flattened and stretched when passing through the guide plate 5, thereby effectively preventing the warning tape 12 from rolling up.

[0037] Alternatively, if Figures 2 to 4 As shown, the circumferential surface of the housing 1 is also provided with a notch 6, and the notch 6 extends along the circumferential direction of the housing 1. The warning tape retracting device also includes a locking member, which includes a locking plate 7 and a push plate 8. Among them, the locking plate 7 is arranged in the accommodating space along the circumference of the winding roller 2, and the locking plate 7 can move between a first position and a second position. The end of the locking plate 7 close to the tape guide roller 4 is the locking end. When the locking plate 7 is in the first position (such as Figure 4 As shown), the locking end blocks the first gap 13, and at this time the locking end presses the warning tape 12 against the tape guide roller 4 to prevent the warning tape 12 from moving; when the locking plate 7 is in the second position (as shown Figure 3 As shown in the figure, the locking end of the locking plate 7 is moved away from the first gap 13 to release the obstruction of the first gap 13, thereby releasing the restriction on the tape guide roller 4 and further releasing the lock of the warning tape 12. The push plate 8 is connected to the locking plate 7, and the push plate 8 extends through the notch 6 to the outside of the shell 1. The push plate 8 can move in the notch 6 along the circumferential direction of the shell 1. Specifically, the operator only needs to push the push plate 8 along the extension direction of the notch 6 to drive the locking end of the locking plate 7 to block the first gap 13, so as to lock the warning tape 12. By setting a locking member, the pull-out length of the warning tape 12 can be locked, thereby improving the convenience of using the device.

[0038] Alternatively, if Figure 4 As shown, both ends of the winding roller 2 are provided with limiting protrusions 9, which protrude from the circumferential surface of the winding roller 2. The limiting protrusions 9 are used to limit the warning tape 12 from detaching from the circumferential surface of the winding roller 2, thereby preventing the warning tape 12 from rolling up after detaching, thereby affecting normal use.

[0039] Alternatively, if Figure 3 As shown, it also includes a handle 10, which is arranged on the top of the shell 1. The handle 10 is arranged to facilitate taking the warning tape retracting device.

[0040] Alternatively, if Figure 3 As shown, at least two supports 11 are provided at the bottom of the housing 1 . The two supports 11 are used to support the housing 1 to stand, thereby facilitating operation by on-site personnel.

[0041] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
