The first embodiment is as follows: the present embodiment provides a coupling assembly for a leisure chair, as shown in fig. 1 to 9, the coupling assembly 1 includes a first connecting member 10 and a second connecting member 11 that can move telescopically with each other, wherein the first connecting member 10 has a telescopic stroke moving relative to the second connecting member 11, and specifically, the telescopic stroke includes an extension stroke for increasing the total length of the coupling assembly 1 and a shortening stroke for reducing the total length of the coupling assembly 1. In addition, a parking mechanism 12 is further disposed between the first connecting member 10 and the second connecting member 11, the parking mechanism 12 includes a pawl 120 and a plurality of ratchet teeth 121 disposed at intervals, wherein the pawl 120 is movably connected to the first connecting member 10, the ratchet teeth 121 are fixedly disposed on the second connecting member 11, specifically, in this embodiment, the ratchet teeth 121 are formed on the second connecting member 11, it is understood that in other embodiments, a ratchet bar fixedly connected to the second connecting member 11 may be manufactured, and the ratchet teeth 121 are disposed on the ratchet bar. The pawl 120 can be engaged with and disengaged from the ratchet 121, and the pawl 120 and the ratchet 121 can cooperate to limit the shortening stroke when performing the extending stroke of the first connecting member 10, specifically, a slot 121a for the pawl 120 to be inserted is formed between adjacent ratchet 121, when the pawl 120 is inserted into the slot 121a, along a direction in which the first connecting member 10 moves and shortens relative to the second connecting member 11, the pawl 120 and the ratchet 121 abut against each other to form a limiting effect, so that the shortening of the first connecting member 10 relative to the second connecting member 11 is limited, and along a direction in which the first connecting member 10 moves and extends relative to the second connecting member 11, a guide surface provided on the pawl 120 abuts against the ratchet 121, and a limiting effect cannot be formed on the first connecting member 10 along the direction, so that the first connecting member 10 can extend relative to the second connecting member 11, that is, that the unidirectional limiting of the first connecting member 10 relative to the second connecting member 11 is realized, and the above-mentioned manner of the pawl 120 and the ratchet 121 cooperate to realize the cooperation belongs to the prior art, and is not described in detail.

In the present embodiment, a holding structure 100 capable of holding the pawl 120 and the ratchet 121 apart is further provided on the first connecting member 10, specifically, the holding structure 100 has a locking portion 100a and a receiving groove 100b, the pawl 120 correspondingly has a rotating end 120a and a locking end 120b, the rotating end 120a is rotatably and movably received in the receiving groove 100b, and the locking end 120b is configured to be capable of engaging with and disengaging from the locking portion 100a. When the locking end 120b is disengaged from the locking portion 100a, the pawl 120 is movable relative to the first link 10, in which state the pawl 120 can cooperate with the ratchet 121 to perform the aforementioned cooperation, and when the locking end 120b is engaged with the locking portion 100a, the pawl 120 is held fixed relative to the first link 10, and in which state the engaging groove 121a formed between the pawl 120 and the ratchet 121 is held apart, thereby releasing the restraining effect in the shortening direction of the first link 10 relative to the second link 11, so that the first link 10 can be movably shortened relative to the second link 11. That is, the retaining structure 100 controls whether the pawl 120 and the ratchet 121 are separated or not, so as to control the one-way limit of the first connecting piece 10 relative to the second connecting piece 11 or release the one-way limit.

In the embodiment, the parking mechanism 12 is arranged between the first connecting piece 10 and the second connecting piece 11, and the pawl 120 and the ratchet 121 cooperate with each other, so that reverse shortening can be prevented in the process of extending the first connecting piece 10 relative to the second connecting piece 11, namely, the first connecting piece 10 is limited in one direction relative to the second connecting piece 11, and thus, in the process of extending the first connecting piece 10 relative to the second connecting piece 11, the one-way limitation can be automatically realized when the pawl 120 is meshed with the ratchet 121, and the locking structure does not need to be operated repeatedly as in the prior art, so that the operation is very convenient; in addition, by providing the holding structure 100 on the first link 10, the relative fixing and moving of the pawl 120 and the first link 10 are realized by the engagement and disengagement between the locking portion 100a and the locking end 120b, when the pawl 120 and the first link 10 can move relative to each other, the above-mentioned cooperation between the pawl 120 and the ratchet 121 is facilitated, and when the pawl 120 and the first link 10 are kept relatively fixed, the separation between the pawl 120 and the ratchet 121 is maintained, so that the first link 10 can be shortened relative to the second link 11, and the relative movement in both the extension direction and the shortening direction is realized.

In this embodiment, the connecting assembly 1 further includes a limiting block 13, specifically, the second connecting member 11 and the limiting block 13 in this embodiment are relatively fixed, the first connecting member 10 is slidably connected to the limiting block 13, and the limiting block 13 has a limiting channel for limiting a sliding path of the first connecting member 10 relative to the second connecting member 11. The first connecting piece 10 and the second connecting piece 11 can be prevented from being separated relatively by the limiting function of the limiting channel. It should be noted that the second connecting member 11 and the limiting block 13 in this embodiment are not fixedly installed together, and the relative fixation in this embodiment means that the second connecting member 11 and the limiting block 13 are installed together on the connected appliance when the connecting assembly 1 is applied, so that the second connecting member 11 and the limiting block 13 synchronously operate and keep relatively fixed when the connecting assembly 1 is used. Of course, it is understood that in other embodiments, the second connecting member 11 and the limiting block 13 may be fixedly installed together by clamping, screwing, or the like. Similarly, in another embodiment, the first connecting member and the limiting block may be fixedly mounted together, and the second connecting member may be designed to be able to move relative to the limiting block in a telescopic manner. Or in other embodiments, the stopper 13 may be formed on the first connecting member 10 or the second connecting member 11 directly by integral molding during manufacturing.

Further, a limiting portion for preventing the pawl 120 from being separated from the first connecting member 10 is formed on the limiting block 13, specifically, in this embodiment, the inner wall of the limiting channel is the limiting portion, which has a limiting effect on the pawl 120 and can ensure that the pawl 120 does not separate from the first connecting member 10.

In this embodiment, a first mounting hole 130 and a second mounting hole 131 which are communicated with the limiting channel are respectively arranged at two ends of the limiting block 13, wherein the first mounting hole 130 is used for mounting the first connecting piece 10 into the limiting channel, and the second mounting hole 131 is used for mounting the second connecting piece 11 into the mounting channel.

For further simple operation, a touch member is further provided in this embodiment for moving the touch pawl 120 relative to the first connecting member 10 so as to enable the locking end 120b to be engaged with or disengaged from the locking portion 100a, the touch member includes a first touch member 111 and a second touch member 112, specifically, the touch member in this embodiment is formed on the second connecting member 11, a long groove 110 is formed along the length direction of the second connecting member 11, the bottom wall of the long groove 110 is provided with the ratchet 121, and two side walls of the long groove 110 respectively form the first touch member 111 and the second touch member 112. Therefore, in the process that the pawl 120 moves telescopically relative to the second connecting piece 11 along with the first connecting piece 10, when the pawl 120 moves to contact with the contact piece, the pawl 120 continues to move and is pressed by the contact piece, so that the first contact piece 111 can press the trigger pawl 120 to enable the locking end 120b to be clamped with the clamping part 100a, and the second contact piece 112 can press the trigger pawl 120 to enable the locking end 120b to be separated from the clamping part 100a. That is, the first connecting member 10 moves relative to the second connecting member 11 in a telescopic manner to the end of the extending stroke and the end of the shortening stroke, and is automatically pressed by the touch member, so that the user does not need to operate the components other than the first connecting member 10 and the second connecting member 11 (i.e. the locking structure does not need to be operated as in the prior art), and the operation is very convenient.

As shown in fig. 9, the pawl 120 in the present embodiment has a locking end 120b, a rotating end 120a, an engaging end 120c, a first driving end 120d and a second driving end 120e, wherein the locking end 120b and the rotating end 120a are as described above, the engaging end 120c is used for engaging with the ratchet 121, the first driving end 120d corresponds to the first touching member 111 and is pressed by the first touching member 111 to drive the pawl 120 to move, and the second driving end 120e corresponds to the second touching member 112 and is pressed by the second touching member 112 to drive the pawl 120 to move.

The above-described positioning groove and receiving groove 100b are formed in the inner wall of the accommodating groove 101, so that when the locking end 120b and the locking portion 100a are disengaged, the pawl 120 can move freely in the accommodating groove 101 while the pawl 120 performs the above-described cooperation with the ratchet 121. It should be noted here that the touching part in this embodiment is formed on the second connecting part, and in other embodiments, the touching part may also be formed in the limiting block, in this embodiment, the limiting block and the second connecting part are kept fixed, and the end parts of both ends of the limiting channel in the limiting block are both provided with a stop, and the stop may be used as the touching part.

In order to make the engaging end 120c capable of being engaged with and disengaged from the engaging slot 121a, and the locking end 120b capable of being engaged with and disengaged from the engaging portion 100a, in this embodiment, the elastic member 14 is disposed between the pawl 120 and the first connecting member 10 to drive the pawl 120 to move relative to the first connecting member 10, the elastic member 14 in this embodiment is a resilient sheet, one side of which abuts against the inner wall of the accommodating slot 101, and the other side of which abuts against the pawl 120, so as to facilitate installation of the resilient sheet and ensure that the resilient sheet is not easy to fall off, in this embodiment, a space for installation of the resilient sheet is formed between the pawl 120 and the top wall of the accommodating slot 101 by the shape of the pawl 120, that is, a notch matched with the shape of the resilient sheet is formed on the pawl 120, and the resilient sheet is installed by using the notch. It is understood that in other embodiments, a spring, a torsion spring, etc. may be used as the elastic member 14, and the installation connection manner may be changed accordingly.

In the connection assembly 1 of this embodiment, the first connecting member 10, the second connecting member 11, the limiting block 13, and the pawl 120 are all made of hard plastic material, and the elastic sheet is a metal elastic sheet. It is understood that in other embodiments, a hard plastic or metal material, or other materials with sufficient hardness may be used for the above components.

Referring to fig. 10 to 15, the process of extending and fixing the connecting member in the present embodiment is described, for convenience of description, two positions are first defined, where the longest position of the first connecting member 10 relative to the second connecting member 11 is the longest extended position, and the shortest position of the first connecting member 10 relative to the second connecting member 11 is the shortest retracted position. Assuming that the first connecting member 10 is initially located at the shortest retraction position relative to the second connecting member 11 as shown in fig. 4, and the engaging end 120c is clamped in the leftmost clamping groove 121a shown in fig. 4, the user applies a force to the first connecting member 10 to rotate the pawl 120 relative to the first connecting member 10 and drive the elastic piece to elastically deform until the engaging end 120c is disengaged from the clamping groove 121a. Then, under the action of the above-mentioned force, the first connecting member 10 carries the pawl 120 to perform an extending stroke relative to the second connecting member 11, and then when the engaging end 120c slides to be aligned with the adjacent slot 121a, under the elastic force of the elastic piece, the pawl 120 returns to rotate relative to the first connecting member 10 until the engaging end 120c is clamped in the slot 121a (as shown in fig. 10), that is, in the above-mentioned process, the first connecting member 10 moves relative to the second connecting member 11 to extend while being relatively fixed at a position different from the original position. Then, the above process is repeated, the first connecting member 10 relatively extends and retracts to different positions relative to the second connecting member 11 and is fixed until the first connecting member 10 moves to the position shown in fig. 11 relative to the second connecting member 11, at this time, the engaging end 120c is clamped into the rightmost clamping groove 121a, the user continues to apply an acting force to the first connecting member 10, the ratchet 121 rotates and is separated from the clamping groove 121a, the first connecting member 10 drives the ratchet 121 to continue to move in the extending direction, so that the first driving end 120d on the pawl 120 contacts and presses against the first touching member 111 on the second connecting member 11 (as shown in fig. 12), the user continues to apply an acting force to the first connecting member 10, the pawl 120 continues to be pressed and rotates and moves relative to the first connecting member 10 (as shown in fig. 13), until the locking end 120b on the pawl 120 is clamped into the clamping part 100a (as shown in fig. 3), at this time, the first connecting member 10 cannot continue to extend and slide relative to the second connecting member 11, and both are located at the longest extending position. At this time, in the direction of the shortening stroke of the first connecting member 10, the user pushes the first connecting member 10 with a small force to slide the first connecting member 10 to the position shown in fig. 14 relative to the second connecting member 11, and the second driving end 120e of the pawl 120 contacts the second triggering member 112 of the second connecting member 11. The user continues to apply an acting force to the first connecting member 10, so that the second driving end 120e of the pawl 120 is pressed by the second touching member 112 of the second connecting member 11, and further the pawl 120 is driven to move and rotate relative to the first connecting member 10, so that the locking end 120b is disengaged from the locking portion 100a (as shown in fig. 15), and then under the elastic force of the elastic piece, the pawl 120 rotates relative to the first connecting member 10 until the engaging end 120c is again engaged with the leftmost engaging groove 121a, that is, the first connecting member 10 retracts to the shortest retraction position relative to the second connecting member 11 as shown in fig. 4.
