Pulley structure group

The present invention relates to a pulley structure group, and in particular to a quick and authentic innovative structural type revealer of a brake rope.

Press, the pulley is a fairly common mechanical part, which can be generally divided into a labor-saving moving pulley or a fixed pulley that changes the direction of the applied force. In the daily life, the most common use of pulleys to improve convenience is to combine the pulley with the drying rack, and to adjust the height of the clothes rail.

Regarding the use of the pulley block on the structure of the drying rack, the new patent case No. M291428 approved by the Bureau of the State Council on June 1, 2006, "the pulley structure of the lifting rack" (hereinafter referred to as the case 428), the case of the case 428 uses the roller, Brake rollers and operating ropes and other components are used to achieve the purpose of lifting and drying the clothes hanger. However, the conventional structural type has found that the following problems still exist in the actual use experience: the brake wheel system of the 428 case is one. Free shaft without shaft, in fact, the free pressure roller without shaft is very easy to lose its proper sensitivity due to the interference of foreign objects; in severe cases, the roller will be idling, making the height of the clothes rod impossible. The control is too low, it is necessary to re-operate, or even the clothes rail is too low, which may cause the hem of the washed clothes or the trousers of the trousers to come into contact with the dirty ground, and must be washed again with water, for the hard laundry For housewives, it is indeed an inconvenient structural design. In addition, the new patent case No. M300220 approved by the Bureau of the People's Republic of China on November 1, 2006, "Structural Improvement of the Pulley Hanger Seat" (hereinafter referred to as the 220 case), the 220 case can improve various problems caused by the aforementioned free pressure wheel. However, there are still the same problems with the 220 case and the 428 case. The roller and the brake roller of the 428 case and the roller and the hammer of the 220 case are single members, so both ends of the two ropes or the single rope can only be synchronized, if the plane level of the 220 case and the 428 case is installed. When the drop is too large, it is necessary to carefully adjust the extension length of the rope on both sides of the roller at the same time to ensure the level of the clothes rail after installation; even if the level has been adjusted during installation, if the level of the clothes pole is affected by improper operation in the future For the average housewife, it will be quite a problem. In addition, the brake wheel of the 428 case and the hammer block of the 220 case directly act on the roller. If the load on the clothes rail is a bed cover or a single weight, all the gravity is from the brake wheel or the hammer block. The top support force will be borne by the axle of the roller, which will seriously affect the service life of the roller.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure of the pulley structure group which is more ideal and practical, is expected by the users, and is also related to the goal and direction of the relevant industry.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

The main purpose of this creation is to provide a pulley structure group, and the technical problem to be solved is to make an innovative breakthrough in how to develop a new type of structure that is more ideal and practical for the drying rack.

The technical feature of the present invention is mainly that the pulley structure group comprises a frame, two pulleys which are arranged on the inner side of the frame, two brake blocks pivoted on the outer side of the frame, and two ends which are respectively disposed in the phase. Corresponding to the pulley and the brake block rope and a top abutting block disposed on the inner bottom of the frame, wherein when the brake block is in a free state, it will be biased outward due to its own gravity, thereby increasing the degree of freedom of the rope; When the rope is led, the rope pushes the brake block outward, so that the rope is in a free state and can move bidirectionally relative to the frame. When the rope is to be fixed, the rope is brought into contact with the corresponding brake block and the brake block is driven. By yawing in the direction of the top abutting block, the corresponding block can be temporarily clamped by the brake block and the top abutting block.

With this innovative and unique design, this creation can be achieved by using the eccentrically pivoted limit block, the brake block that does not directly act on the pulley, and the topping block made of the material with low friction coefficient. Overcoming the lack of correct operation of the free pressure wheel, greatly reducing the shear force on the pulley axle, prolonging the service life of the pulley, reducing the friction caused by the compression of the brake wheel before the rope positioning, and other practical progress and better industrial economy (utilization) )benefit.

Please refer to Figures 1, 2, 3, and 4 for a preferred embodiment of the present pulley structure set, but such embodiments are for illustrative purposes only and are not limited by this structure in the patent application.

A rope 40 corresponding to the pulley 20 and the brake block 30 and a top abutting block 50 disposed at the inner bottom of the frame 10 are provided. When the user pulls down the rope 40, the rope 40 pushes the brake block 30 outward, so that the rope 40 is in a free state and can move bidirectionally relative to the frame 10, and when the rope 40 is to be fixed, the rope 40 is The corresponding brake block 30 contacts and drives the brake block 30 to yaw in the direction of the top abutment block 50, so that the corresponding cable 40 can be temporarily clamped by the brake block 30 and the top abutment block 50. The aforementioned single rope 40 can also be replaced by two ropes 40.

The frame 10 is provided with a partition 11 which simultaneously separates the two pulleys 20 from the two brake blocks 30 such that each of the pulleys 20 respectively corresponds to a brake block 30, so as to avoid the adjacent ropes 40 from each other. Tangle or rub to extend the life of the rope 40.

Due to its own weight structure and the technical means of eccentricity pivoting on the frame 10, the brake block 30 causes the brake block 30 to be biased outward due to its own gravity, thereby improving the degree of freedom of the rope 40. The surface of each brake block 30 is laterally provided with a plurality of ribs 31 to increase the friction when the rope 40 is forced.

In the preferred embodiment of the present invention, the abutting block 50 is made of a structure that is mounted in the frame 10 and is made of a low friction coefficient, such as a hard plastic.

With the above structural composition design, the operation of the present invention is explained as follows: As shown in FIG. 4, the two ends of the rope 40 of the present invention are respectively connected to an external fixed pulley 60, and then connected to A clothes rail 70 corresponds to both ends. Please refer to Figure 5 as shown in Figure 5. When you want to hang the clothes on the clothes pole 70 to expose or dry the clothes, first pull down the rope 40 (as indicated by the arrow L1 in Figure 5), so that the brake block 30 is along The direction of the arrow L2 is outwardly biased, and the rope 40 is no longer tightened. As shown in Fig. 6, the rope 40 is in a free state, and when the rope 40 is synchronously moved in the direction of the arrow L3, it can be horizontal. The method reduces the height of the clothes rail 70, and when the ropes 40 are synchronously moved in the direction of the arrow L4, the height of the clothes rail 70 can be raised horizontally; when adjusting to an appropriate height, please refer to As shown in Fig. 7, the two sides of the rope 40 can be synchronously displaced toward the brake block 30, and then the rope 40 is moderately relaxed to move in the direction of the arrow L5, and the brake block 30 is biased in the direction of the arrow L6 to be biased again. The rope 40 is convenient for the user to hang the clothes to be dried on the clothes rail 70, and after hanging the clothes to be aired, repeat the action described in the above FIG. 5, so that the rope 40 is again in a free state. Then, the two sides of the rope 40 are synchronously pulled in the direction of the arrow L3 shown in Fig. 6, that is, When the clothes rail 70 is raised to a moderate height, as shown in FIG. 7, the two sides of the rope 40 can be synchronously shifted toward the brake block 30, and then moderately. The rope 40 is relaxed to move in the direction of the arrow L5, and the brake block 30 is biased in the direction of the arrow L6, so that the rope 40 can be tightened again to position the clothes bar 70 at the height set by the user.

In addition, the frame 10 of the present invention is provided with two pulleys 20, and the brake block 30 is eccentrically pivoted, and each brake block 30 is separately corresponding to a pulley 20, so that the two sides of the rope 40 can be separately operated.
