Description

Technical Field

[0001] The utility model relates to a clothesline tightening mechanism, in particular to a clothesline tightening mechanism. Background Art

[0002] Clotheslines are one of the necessities in today's home life. The existing clotheslines that are widely used all use two ends of the clothesline fixed on the wall or a vertical clothesline for normal drying of clothes. Although the above method can simply and quickly dry clothes, it still has some disadvantages. For example, during the clothes drying process, due to the weight of the clothes and the moisture in them, the clothes gradually move towards the middle of the clothesline under the action of gravity, which results in fewer clothes at both ends of the clothesline, while the clothes in the middle of the clothesline are more and heavier, causing the middle of the clothesline to fall. During the clothes drying process, the clothes may touch the ground, causing the clothes to be dirty, and they need to be washed and dried again. During the drying process, more clothes are concentrated in the middle of the clothesline, which easily leads to a short distance between clothes, poor ventilation, and a slow drying speed of clothes. In some areas with high humidity or in the rainy season, clothes are difficult to dry quickly, and severe cases may even cause the clothes to mold. The above factors bring some troubles to the drying of clothes.

[0003] In the patent with patent number CN218147434U, the above requirements are met, but two limit blocks, buckles and related slots are used in the process of limiting the pawl, which has many parts and is complicated to install and manufacture. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a clothesline tightening mechanism.

[0005] To achieve the above object, the present utility model provides the following technical solutions: It includes a housing, a rotating gear, a wire reel, a clothesline, a blocking block and a control mechanism. The rotating gear is rotatably arranged in the housing. The wire reel is concentrically arranged with the rotating gear and rotates with the rotating gear. An outlet head is arranged on the housing. The clothesline is wound in the wire reel and the clothesline is linked with the outlet head. The blocking block is rotatably arranged in the housing. The blocking block has an engaging position meshing with the rotating gear. The control mechanism has a fixed state of fixing the blocking part at the engaging position. The control mechanism includes a control block, a linkage rod, a control spring and a blocking spring. The blocking block has a blocking part. The control block is rotatably arranged in the housing. The control block has a control part opposite to the blocking part. The control block is also provided with a linkage part. The linkage rod is rotatably arranged at the linkage part. The blocking spring is arranged on the blocking block and drives the blocking part to rotate towards the direction where the control part is located. The control spring is arranged between the linkage rod and the housing. During the rotation process, the control part has a blocking position where it abuts against the blocking part and a separation position where it separates from the blocking part. The fixed point of the control spring on the housing is located between the control part rotating from the separation position to the blocking position, so that the control spring can provide corresponding beneficial maintaining forces when rotating to the separation position and the blocking position. The blocking spring can be a torsion spring.

[0006] By adopting the above technical solutions, when in use, the clothesline is pulled out through the outlet head, and then the outlet head is fixed at the other end. Then, the blocking part is fixed at the engaging position through the control mechanism. At this time, the outlet head cannot move anymore. If it is necessary to adjust the length of the clothesline, the fixing of the blocking part can be released through the control mechanism at this time, and then the length of the corresponding clothesline can be adjusted. The adjustment process is convenient. When it is necessary to fix the blocking block, rotate the control block until the control part is at the blocking position. At this time, part of the blocking block meshes with the rotating gear, and the blocking part abuts against the control part under the action of the blocking spring and the control spring, so that the blocking block is fixed. During this process, the driving of the control spring on the control part is divided into two parts. One is when the control part is at the blocking position, the control spring drives the control part to abut against the blocking part. And when the control part rotates past the middle position of the control spring through the rotation of the control block, the control spring will drive the control part away from the blocking part and will not move randomly. That is, the control of the control part at two positions is completed through one control spring, reducing the use of parts.

[0007] The present utility model is further arranged as: It further includes a limiting column. The limiting column is arranged in the housing. The control block is rotatably arranged on the limiting column. A limiting block is fixedly arranged on the limiting column. A limiting ring is also arranged on the control block. A rotating groove for the circumferential relative rotation of the limiting block is arranged on the limiting ring. Similarly, the blocking block can also be limited according to such a mechanism. Since the structures are the same, they will not be elaborated here.

[0008] By adopting the above technical solution, the arrangement of the limiting block and the limiting groove prevents the control block from rotating by an excessive angle.

[0009] The present utility model is further configured as: It further includes a control rod, which is arranged on the control block and controls the rotation of the control block, and the control rod extends outside the housing.

[0010] By adopting the above technical solution, the arrangement of the control rod facilitates the use by the user.

[0011] The present utility model is further configured as: It further includes a tightening knob, which is arranged on the housing and rotates concentrically with the wire reel.

[0012] By adopting the above technical solution, the arrangement of the tightening knob facilitates the user to adjust the length.

[0013] Beneficial effects: The driving of the control spring on the control part is divided into two parts. One is that when the control part is in the blocking position, the control spring drives the control part to abut against the blocking part. And when the control part rotates through the middle position of the control spring by rotating the control block, the control spring will drive the control part away from the blocking part and will not move randomly, that is, the limiting of the control part at two positions is completed by one control spring, reducing the use of parts.

[0022] As Figures 1-5 shown, the present utility model discloses a clothesline tightening mechanism, which includes a housing 1, a rotating gear 2, a wire reel 3, a clothesline, a blocking block 5 and a control mechanism 6. The rotating gear 2 is rotatably arranged in the housing 1. The wire reel 3 is concentrically arranged with the rotating gear 2 and rotates with the rotating gear 2. An outlet head 7 is arranged on the housing 1. The clothesline is wound in the wire reel 3 and the clothesline is linked with the outlet head 7. The blocking block 5 is rotatably arranged in the housing 1. The blocking block 5 has an engaging position meshing with the rotating gear 2. The control mechanism 6 has a fixed state of fixing the blocking portion 51 at the engaging position. When in use, the clothesline is pulled out through the outlet head 7, and then the outlet head 7 is fixed at the other end. Then, the control mechanism 6 is used to fix the blocking portion 51 at the engaging position. At this time, the outlet head 7 cannot move any more. If the length of the clothesline needs to be adjusted, the fixing of the blocking portion 51 can be released through the control mechanism 6 at this time, and then the length of the corresponding clothesline can be adjusted, and the adjustment process is convenient.

[0023] The control mechanism 6 includes a control block 61, a linkage rod 62, a control spring 65 and a blocking spring 66. The blocking block 5 has a blocking portion 51. The control block 61 is rotatably arranged in the housing 1. The control block 61 has a control portion 63 opposite to the blocking portion 51. The control block 61 is also provided with a linkage portion 64. The linkage rod 62 is rotatably arranged in the linkage portion 64. The blocking spring 66 is arranged on the blocking block 5 and drives the blocking portion 51 to rotate towards the direction where the control portion 63 is located. The control spring 65 is arranged between the linkage rod 62 and the housing 1. During the rotation process, the control portion 63 has a blocking position where it abuts against the blocking portion 51 and a separation position where it is separated from the blocking portion 51. The fixed point of the control spring 65 on the housing 1 is located between the separation position and the blocking position of the control portion 63, so that the control spring 65 can provide corresponding beneficial maintaining forces when rotating to the separation position and the blocking position. The blocking spring 66 can be a torsion spring. When it is necessary to fix the blocking block 5, rotate the control block 61 until the control portion 63 is in the blocking position. At this time, a part of the blocking block 5 meshes with the rotating gear 2, and the blocking portion 51 abuts against the control portion 63 under the action of the blocking spring 66 and under the control spring 65, so that the blocking block 5 is fixed. During this process, the driving of the control spring 65 on the control portion 63 is divided into two parts. One is that when the control portion 63 is in the blocking position, the control spring 65 drives the control portion 63 to abut against the blocking portion 51. And when the control portion 63 rotates past the middle position of the control spring 65 by rotating the control block 61, the control spring 65 will drive the control portion 63 away from the blocking portion 51 and will not move randomly. That is, the control of the control portion 63 at two positions is completed by one control spring 65, reducing the use of parts.

[0024] It further includes a limit post 8. The limit post 8 is arranged in the housing 1. The control block 61 is rotatably arranged on the limit post 8. A limit block 81 is fixedly arranged on the limit post 8. A limit ring 82 is also arranged on the control block 61. A rotating groove 83 for the circumferential relative rotation of the limit block 81 is arranged on the limit ring 82. Similarly, the blocking block 5 can also be limited according to such a mechanism. Since the structures are the same, they will not be elaborated. The setting of the limit block 81 and the limit groove makes the control block 61 not rotate too large an angle.

[0025] It further includes a control rod 9. The control rod 9 is arranged on the control block 61 and controls the rotation of the control block 61. The control rod 9 extends outside the housing 1. The arrangement of the control rod 9 facilitates the use by the user.

[0026] It further includes a tightening knob 11. The tightening knob 11 is arranged on the housing 1 and rotates concentrically with the wire reel 3. The arrangement of the tightening knob 11 facilitates the user to adjust the length.

[0027] Working process: When in use, pull out the clothesline through the outlet end 7, then fix the outlet end 7 at the other end, and then rotate the control block 61. When the control part 63 passes through the relative position with the control spring 65, the control spring 65 drives the control part 63 to fit with the blocking part 51. At this time, a part of the blocking block 5 meshes with the rotating gear 2, and the blocking part 51 abuts against the control part 63 under the control spring 65 under the action of the blocking spring 66, so that the blocking block 5 is fixed. At this time, the outlet end 7 cannot move anymore. If it is necessary to adjust the length of the clothesline, the fixing of the blocking part 51 can be released through the control mechanism 6 at this time, and then the length of the corresponding clothesline can be adjusted.
