Example 1

A lifting-type drying rack includes at least two lifting seats 8 arranged in a row, and each lifting seat is movably connected with two horizontal rods 23 in the front-rear direction; each horizontal rod is provided with a plurality of self-locking drying rods 10 ; The upper end of the self-locking drying rod is connected to the horizontal rod, and the lower end is movably connected to another horizontal rod 23 in the front-rear direction, and each self-locking drying rod is connected to rise and fall simultaneously through the horizontal rod.

The lower ends of the two left and right self-locking drying rods symmetrically connected are connected together through a fixing base 5, and the two self-locking drying rods are hinged to the fixing bases respectively; a horizontal rod 23 at the lower end of the self-locking drying rods passes through each of the fixing bases 5.

A diamond-shaped telescopic lifting frame 19 is mounted on the lifting base 8 through a lifting slide 21, and an upper end of the diamond-shaped telescopic lifting frame is slidably disposed in the lifting slide 21 of the mounting base 22.

The left and right sides of the lifting seat are provided with slideways 11 symmetrically. The slideway is inclined downward from the end of the lifting seat to the middle of the lifting seat; the horizontal bar at the upper end of the self-locking drying rod is connected to the lifting seat through the slideway to lift. The seat is connected to the mounting seat through a diamond-shaped telescopic lifting frame; there are sliders or wheels on the horizontal rod that can slide in the slideway.

A V-shaped folding frame 25 is also articulated between the lifting base and the diamond-shaped telescopic lifting frame, and an inverted V-shaped folding frame 25 is also articulated between the diamond-shaped telescopic lifting frame and the mounting base.

A self-locking drying rod includes a rod body 1, a tongue-shaped cavity 2 having a groove-shaped structure on one side of the rod body, and at least one hook 4 fixed on one side of the tongue-shaped cavity, and a lock corresponding to the hook is provided in the tongue-shaped cavity. Tongue 3.

In the self-locking drying rod, the lock tongue is a rotatable lock tongue, and the lock tongue is rotatably installed in the lock tongue cavity through the rotating shaft 9; an anti-self-locking structure is installed in the lock tongue cavity. The push rod 6 moving in the cavity is fixed with a push block 7 on the push rod. The push block corresponds to the lock tongue one by one. The lower end of the push rod is connected with a push mechanism, and the push mechanism is installed in a self-locking drying rod. The front and rear of the horizontal rod at the lower end of the self-locking drying rod are respectively connected to the pull rope 18. When the horizontal rod is raised to the lifting base, it naturally rises against the lifting base at the same time. The pulling rope is used to pull the lifting base and the self-locking drying rod. Lifting.

In the self-locking drying rod, the pushing mechanism at the lower end of the push rod includes a gear 15 and a rack 16 that mesh with each other. The end of the pushing rod is fixed to the rack. The gear is rotatably installed in the self-locking drying rod. The seat 5 is fixedly connected.

A gear control lever 17 is vertically mounted on the fixed base, and the gear control lever fixedly connects the gear of the self-locking drying rod with the fixed base.

The gear control lever 17 only controls the gears in a self-locking drying rod, and the gear drives the rack, or a long rod that controls multiple self-locking drying rods side by side. Gear control levers can use pins that are not circular in cross-section, such as semi-circular, triangular, rectangular, oval, and so on. The pin holes on the fixed seat and the pin holes on the gear correspond to the cross-section of the pin. Prevent the gear and the fixed base from rotating relative to each other.

The two end faces of the gear can be provided with a cylindrical shaft 26 integrated with the gear, the shaft and the gear have a common central axis, and the two sides of the rod body of the self-locking drying rod are provided with round holes at the contact points of the two end faces of the gear. The circular hole is sleeved on the shaft, and there is relative rotation between the circular hole and the shaft. In this way, a rotatable mounting gear 16 inside the rod body can be achieved, that is, the rod body of the self-locking drying rod rotates around the shaft 26 at both ends of the gear.

The left and right ends of the lifting seat 8 can be installed with support rods 20 in the front-rear direction, and the fixed seat 5 can also be fixedly installed or movably installed with the support rods 20 in the front-rear direction. The support rods are used for drying large items such as quilts and blankets.

The horizontal bar in the front-rear direction of the lower end of the self-locking drying rod passes through each fixed seat of the lower end of the self-locking drying rod to realize the simultaneous lifting and lowering of each self-locking drying rod. It can also be a gear control lever 17 installed vertically on the fixed seat. The fixed bases are penetrated together to realize the synchronous lifting of the self-locking drying rods of each basic unit; when the lower ends of the self-locking drying rods on the left and right sides are hinged together, the same hinge shaft is used at the hinges to connect each The basic units are connected together to realize the synchronous lifting of the self-locking drying rods of each basic unit.

When the self-locking drying rod adopts a rotatable tongue, the drying rod can realize the functions of self-locking and automatic unlocking. Referring to FIGS. 5 and 6, when the drying rack is level (see FIG. 5), the tongue 3 Under the action of gravity, turn out the lock tongue cavity 2 around the rotating shaft 9 and abut the top of the hook 4. When hanging the clothes, push the clothes along the hook 4 from right to left (refer to the direction in FIG. 5) to hang on the hook During the period of time, the clothing is in contact with the bolt 3 and drives the bolt 3 to rotate clockwise around the rotating shaft 9. The bolt 3 is partially hidden in the bolt cavity 2. A gap is created between the bolt 3 and the hook 4. The clothes are conveniently hung on the On the hook 4, at the same time, under the gravity of the bolt 3, the end of the bolt 3 abuts on the clothing; when the external force such as the wind is applied, the clothing generates a frictional force with the bolt 3 when it falls down, and the frictional force Under the action of the clothing, the lock tongue 3 is rotated counterclockwise around the rotating shaft 9 by the clothes, the gap between the lock tongue 3 and the hook 4 gradually becomes smaller, and the clothes are tightly squeezed between the lock tongue 3 and the hook 4, thereby ensuring the clothes Without being blown off, the self-locking function of the clothes is realized.

When it is necessary to take the clothes, the drying rod is erected (vertical to the horizontal direction as shown in Fig. 6). Under the action of the gravity of the lock tongue 3, relative rotation occurs between the rotating shaft 9 and the lock tongue 3, and the lock tongue 3 completely enters the lock tongue cavity. In 2, the distance between the lock tongue 3 and the hook 4 is large at this time, and the lock tongue 3 is no longer in contact with the clothes, and the clothes can be directly removed.

In actual use, even after the lock tongue 3 enters the lock tongue cavity 2, when the clothes are thick, the lock tongue 3 will still be in contact with the clothes. At this time, when the clothes are taken, the lock tongue 3 and the clothes are rubbed too tightly. There is a phenomenon that the tongue 3 is stuck. When the drying rod is erected, the phenomenon that the tongue 3 still does not return to the tongue cavity 2 or the tongue 3 still rotates around the shaft 9 under the frictional force with the clothes. Out of the locking tongue cavity 2 and self-locking is generated, in order to avoid such a self-locking situation, in particular, an anti-self-locking structure is added, that is, a pushing rod 6 capable of sliding back and forth is provided in the locking tongue cavity 2, and each of the pushing rods 6 is provided The pushing block 7 corresponding to the bolt 3 is moved by sliding the pushing lever 6. When the hook 4 is not required to be self-locked, the sliding pushing lever 6 controls the pushing block 7 to move to the inner wall of the bolt cavity 2 and the bolt 3 To prevent the lock tongue 3 from rotating counterclockwise, to avoid self-locking, so as to facilitate taking clothes.

The pushing mechanism at the lower end of the push rod, that is, the gear 15 and the rack 16, because the lever 1 is hinged to the fixed base. When the lever 1 rotates along the hinge axis with the gear, the fixed base does not rotate, the gear does not rotate, and the lever drives the rack The gear teeth are engaged to rotate, so that the push rod 6 in the lock tongue cavity 2 and the rod body are relatively displaced in the length direction. The push rod 6 is provided with a push block 7 corresponding to the lock tongue 3, and the push rod 6 is along the length in the rod body. The sliding in the direction realizes the movement of the pushing block 7. When the rod body is turned from the vertical direction to the horizontal direction (this is also the process of raising the self-locking drying rod after hanging the clothes on the hook), the push block is moved a short distance in the direction close to the fixed seat 5. When the rod body is turned from the horizontal direction to the vertical direction (this is also the process of lowering the self-locking drying rod and removing the clothes from the hook), the pushing block is moved a short distance away from the fixed seat 5 to push Quickly push the top of the bolt to turn away from the fixed base, and the lower part of the bolt is turned closer to the fixed base (taking the self-locking drying rod on the right as an example, when the lever is turned counterclockwise, the bolt is turned clockwise), so Open the opening of the hook to avoid the problem that the locking tongue can not open the hook and realize anti-self-locking. In this way, during the process of rotating the drying rod, the pushing rod 6 can be automatically moved in the tongue cavity 2 at the same time, thereby completing the anti-self-locking operation.

When the device is in use, when the clothes are hung up, it falls down as a whole. The left and right self-locking drying rods are basically vertical together and hung together under the middle of the lifting seat, which greatly reduces the occupied space, especially on the balcony. Such a narrow place does not affect walking. At this time, the self-locking drying rod is erected after rotating around the fixed seat, and the clothes are conveniently hung on the hook. When the clothes are hung for drying, the whole rises and is close to the ceiling. The left and right self-locking drying poles are inclined or horizontal, occupying only overhead space, not occupying the middle and lower spaces, and do not affect people's activities. At this time, the self-locking drying rod tends to be horizontal, and the hooks of the drying rod are in a self-locking state, and the laundry will not fall, and the laundry can be dried.

A hook is fixed on the drying rod of the present invention, and the clothes can be directly hung and dried without the need of other auxiliary hangers. The lock tongue cavity has a rotatable lock tongue, which can "lock" the item on the hook. When drying the item, It will not fall; it can be unlocked by rotating the drying rod, saving time and effort, and an anti-self-locking structure is provided in the lock tongue cavity. When taking clothes, it does not self-lock, avoiding the phenomenon that the clothes cannot be taken off, which improves the The device is convenient to use; the drying rod in the present invention can hang a large variety of clothes, not only to dry clothes, but also to dry shoes, hats, socks, gloves, etc., and it can be guaranteed to be stable and not fall during the drying process. .
