[0021] As in Fig. 1 to 12, this invention provides a folding chair frame with a table top, comprising a main body 1 and a table top 3; wherein the main body 1 includes a base 11 and a main support frame, the base 11 and the main support frame are connected to each other, and both are foldable to reduce storage space; accordingly, the base 11 is connected to the connecting part 2, and the table top 3 is rotatably connected to the connecting part 2, so that the table top 3 can assume a use state and a folded state, the two states being switchable by rotation; specifically, in the use state, the table top 3 is disposed on the outside of the base 11 and is in a horizontal orientation with the table top facing upward, and can be used to accommodate a variety of items such as teacups, electronics, and the like;When the table top 3 is in the folded state, the main body 1 has two states: in use or in the folded state. When the entire folding of the main body 1 and the table top 3 is completed, the table top 3 is located in the storage space enclosed by the folded base frame 11. This increases the thickness and width of the folded folding chair frame. As a result, the folded volume of the folding chair frame does not increase, so the storage space does not increase and the number of transportations can be increased. In addition, the table top 3 can be hidden on the inside of the folded base frame 11, which prevents damage to the table top 3 during transportation and ensures the quality of the table top 3.when the main body 1 is in use, the table top 3 is located inside the unfolded base 11 to avoid occupying the unfolded space and hindering the activities of external people.;

[0022] In particular, the connecting part 2, as in Fig. 2 to 3, as long as it is capable of ensuring the rotation of the table top 3 from the outside of the base frame 11 to the inside of the base frame 11, the folding rotation of the table top 3 in the unfolded state of the base frame 11 is completed by folding the base frame 11 and the main support frame after the table top 3 is rotated into the inside of the base frame 11, and after the folding is completed, the table top 3 is hidden in the folded chair frame; specifically, the connecting part 2 in this embodiment includes a connecting plate 21, a pivot block 22, and a connecting rod 23, one end of the connecting plate 21 being attached to the base frame 11 and the other end being free, and the free end of the connecting plate 21 being disposed within the storage space enclosed by the folded chair frame 11;Apart from the fact that the entire connecting plate 21 is attached to the end of the base frame 11, the rest is located in the storage space enclosed by the folded base frame 11, so that the thickness of the folding chair frame does not increase after folding; accordingly, the pivot block 22 is provided with a sliding hole 221, the axis of the sliding hole 221 being perpendicular to the side of the base frame 11, and the connecting rod 23 is slidably and rotatably attached to the sliding hole 221 at one end, and the other end is connected to the table top 3, so that the table top 3 is slidable and rotatable along the axis of the sliding hole 221;Since the table top 3 rests horizontally on the base frame 11 in use, the following construction is provided to enable the rotational movement: the table top 3 is slidably mounted along the sliding hole 221, whereby it moves away from the base frame 11 in a direction perpendicular to the side surface of the base frame. This leads to the cancellation of the support effect between the table top 3 and the base frame 11;accordingly, the end of the connecting rod 23 has a limiting plate 25, the limiting plate 25 being arranged on the outside of the sliding hole 221 and having an outer diameter larger than the opening of the sliding hole 221, in order to prevent the end of the connecting rod 23 from coming off the sliding hole 221 when the table top 3 is moved in a direction perpendicular to the side of the base 11 in a direction away from the base 11, after which the table top 3 can be rotated about the axis of the sliding hole 221 from the horizontal to the vertical and also in the vertical or in the middle tilting direction, provided that it is possible to make the table top 3 rotatable towards the inside of the base 11 in this position;Furthermore, the rotating block 22 at the free end of the connecting plate 21 is rotated, and after rotation, the table top 3 can be rotated again together with the rotating block 22, so that the table top 3 can be rotated from the outside to the inside of the base frame 11, thus switching between the use state and the folded state. A schematic representation of the folding process of the table top 3 is shown in FIG. Fig. 4 to 6 can be seen.

[0023] In particular, the presence of the connecting plate 21 may cause the connecting rods 23 located therein to no longer connect when the folding chair frame is folded. Therefore, the connecting plate 21 is provided with a recess 24, and the blocked connecting rod 23 can be arranged further into the recess 24 to achieve the original folding position and prevent the inner connecting rod 23 from being blocked by the connecting plate 21, thereby increasing the thickness of the folded folding chair frame. Furthermore, the end of the connecting rod 23 connected to the table top 3 is U-shaped and connected with bolts, which increases the stability of the table top 3.

[0024] In this embodiment, the axis of the rotating block 22 is arranged vertically; when the table top 3 is rotated into the interior of the base 11, even if the position of the table top 3 deviates during the folding operation of the base 11 and the main support frame, the table top 3 is forced to be rotated into the storage space enclosed by the folded base 11, thereby not increasing the overall volume after folding.

[0025] In particular, the table top 3 is provided with at least one storage slot 31, wherein the plurality of storage slots 31 have different shapes, in particular, the shape of the storage slot 31 can be cylindrical, rectangular, square, etc., and can be selected according to the needs of the market user for storing tea cups, electronic products, food, etc.be designed; and in particular, the table top 3 is provided with a storage hole 32, and the side wall of the table top 3 is provided with a connecting slot, wherein the connecting slot is connected to the storage hole 32, in this embodiment, the storage hole 32 comprises conical holes and columnar holes running from top to bottom, and the connecting slot is connected to both the conical holes and the columnar holes and can be used to store the tall cups, which can be guided by the support feet from the connecting slot to the storage holes 32 and placed there.

[0026] In particular, the base frame 11 and the main support frame, as shown in Fig. 1, various forms of folding structures are shown. In this embodiment, the base frame 11 includes a front frame 111 and a rear frame 112. A linkage unit is arranged between the center of the front frame 111 and the rear frame 112. The linkage unit includes a first rotary disk and a second rotary member, the second rotary member including two second rotary disks. The main support frame includes a backrest support 12, a legrest 13, a seat frame 14, and two armrest supports 15. The front frame 111, the rear frame 112, the backrest support 12, the legrest 13, and the seat frame 14 are all U-shaped structures with the following specific connection relationships: the two upper ends of the front frame 111 and the rear frame 112 are rotatably connected to the two armrest supports 15, respectively;The two lower ends of the backrest support 12 are pivotally connected to the two rear ends of the seat frame 14, with the upper end of the backrest support 12 being free, and the two lower portions being pivotally connected to the rear ends of the armrest support 15; the two upper ends of the legrest 13 are pivotally connected to the two front portions of the armrest support 15, with the lower end of the legrest 13 being free, and the two upper portions of the legrest 13 being pivotally connected to the two front portions of the seat frame 14;One end of the two second rotating disks is arranged on both sides of the support rod in the rear frame 112 and is rotatably connected by a bolt, and the other end is connected as a whole by a connecting shaft and is rotatably connected by a bolt to the support rod in the seat frame 14 and one end of the first rotating disk, and the other end of the first rotating disk is rotatably connected by a bolt to the support rod in the front frame 111, so that the linkage unit can limit the unfolding angle of the lower frame 11 and support the seat frame 14, whereby the main body 1 becomes more stable and load-bearing after the entire unfolding. Preferably, the connecting shaft is provided with a mounting groove that fits with the support rod in the rear frame 112, and in the unfolded state, the support rod in the rear frame 112 is located within the mounting groove.;

[0027] As in Fig. 1, the mounting groove is mounted on the connecting axis between the second turntables in the unfolded state in connection with the support rod inside the rear frame 112, and when the whole is folded, as shown in Fig. 7 to 8, the table top 3 is first folded to the inside of the base frame 11, then the front frame 111 and the bottom of the rear frame 112 are close to each other, and the second turntable rotates in a direction away from the rear frame 112 and simultaneously drives the rear end portion of the seat frame 14 to rotate in a direction close to the rear frame 112; simultaneously, the free end of the backrest support 12 is rotated in a direction near the upper end surface of the seat frame 14, and the legrest 13 is rotated in a direction near the lower end surface of the seat frame 14, and finally folded.

[0028] Specifically, in this embodiment, based on the structure of the base frame 11, the mounting end of the connecting plate 21 is mounted in the center of the rear frame 112, and the end of the table top 3 remote from the rear frame 112 is provided with a support slot 33 compatible with the front frame 111. After the table top 3 is rotated to a horizontal state, the support slot 33 is located on the upper side of the front frame 111, and the support rod inside the front frame 111 is located in the support slot 33 to complete the support of the table top 3. When the table top 3 needs to be folded, the table top 3 is first rotated upward and then moved toward the outside along the sliding hole 221, so that the support rod in the front frame 111 is separated from the support slot 33, and then it is possible to rotate the table top 3 in a downward direction.

[0029] In particular, the armrest support 15 in this embodiment comprises, as in Fig. 9 to 12, an armrest 151, a slide bar 152, and a locking unit; the front and rear ends of the armrest 151 are rotatably connected to the lower portion of the backrest support 12 and the upper end of the legrest 13, respectively, and the slide bar 152 is provided inside the armrest 151 for supporting the armrest 151; the locking unit includes a sliding block 153 and a locking part, wherein the sliding block 153 is provided with a sliding hole (not shown), the sliding block 153 is connected to the sliding rod 152 through the sliding hole, and the sliding block 153 can slide along the longitudinal direction of the sliding rod 152, the two upper ends of the front frame 111 and the rear frame 112 are both rotatably connected to the sliding block 153 to support the armrest support 15, and the locking part is used to lock the sliding rod 152;In particular, when the locking part is locked, the sliding block 153 is prevented from sliding relative to the sliding rod 152, thereby preventing the sliding rod 152 from rotating, and the backrest support 12 and the legrest 13 can be adjusted in angle. After the locking part is unlocked, the sliding block 153 and the sliding rod 152 can slide relative to each other, the sliding rod 152 rotates, the backrest support 12 and the legrest 13 can be adjusted in angle, and after the angle is adjusted, locking can be performed by the locking part.

[0030] Specifically, in this embodiment, the locking member includes a locking block 154, a locking housing 155, and an elastic member for achieving locking, wherein the locking housing 155 is provided on the sliding block 153, the locking block 154 is provided on the locking housing 155, a locking portion is fixed to the upper end portion of the locking housing 155 and disposed above the slide bar 152, and the elastic member is provided between the upper side wall of the locking housing 155 and the upper end portion of the sliding block 153;Through the interaction of the locking block 154 with the lower side wall of the sliding block 153, the locking block 154 resists the lower side wall of the sliding block 153, causing the entire locking block 154 to move downward, the locking portion downward, and finally against the upper side wall of the sliding rod 152. The elastic member has a biasing force, and at the same time, the locking block 154 causes the sliding block 153 to move upward. Under the action of the elastic part, the locking block 154 is pressed against the lower side wall of the sliding block 153, and the inner side wall of the sliding block 153 is pressed against the lower side wall of the sliding rod 152, and at the same time, the upper and lower side walls of the sliding rod 152 are locked, thereby improving the locking effect;Accordingly, to unlock, only the locking block 154 needs to be moved in the opposite direction, the locking block 154 no longer resists the lower side wall of the sliding block 153, the inner side wall of the sliding block 153 no longer resists the lower side wall of the sliding rod 152, and the locking portion moves upward under the action of the elastic part, no longer snaps against the upper side wall of the sliding rod 152, and the initial state is restored.;

[0031] In order to specifically achieve the locking of the slide rod 152 by the locking member, in this embodiment, the locking housing 155 is provided on the outer periphery of the slide block 153 so that the locking block 154 is located directly below the slide rod 152; accordingly, the upper end of the slide block 153 is provided with a notch connected to the sliding hole therein, so that when the locking member is required to lock the slide rod 152, the locking portion can be guided downward through the notch into the sliding hole and engage with the upper side wall of the slide rod 152; at one end of the locking block 154, an eccentric wheel 157 is provided and rotatably mounted on the locking housing 155, and the other end is free, the rotation axis of the locking block 154 being located below the lower side wall of the slide block 153.and the distance between the rotation axis of the locking block 154 and the lower side wall of the sliding block 153 is smaller than the maximum radius of the eccentric wheel 157, when rotating the free end of the locking block 154 to drive the eccentric wheel 157, the outer side wall of the eccentric wheel 157 first contacts the lower side wall of the sliding block 153; with continued rotation of the eccentric wheel 157, the sliding block 153 is forced to move upwards until the inner side wall of the sliding block 153 comes into contact with the lower side wall of the sliding rod 152 and the sliding block 153 stops its movement, at the same time the locking housing 155 moves downwards, and the locking portion moves downwards until the outer side wall at the maximum radius of the eccentric wheel 157 comes into contact with the lower side wall of the sliding block 153, and the locking housing 155 stops its downward movement,At this time, the locking portion and the upper side wall of the slide bar 152 abut each other, and at the same time, the elastic member between the upper end portion of the locking housing 155 and the upper side wall of the slide block 153 is preloaded. The preload of the elastic member causes the locking housing 155 to tend to move upward, so that the eccentric gear 157 continues to abut against the lower side wall of the slide block 153. This allows the slide block 153 to continuously press against the lower side wall of the slide bar 152, thereby completing the press-locking of the upper and lower side walls of the slide bar 152.

[0032] Specifically, the elastic member includes two elastic disks 156, one end of each of the two elastic disks 156 being connected to the outer side wall of the upper end portion of the locking housing 155, and the lower end being in contact with the upper side wall of the sliding block 153, the elastic disks 156 having a certain degree of elasticity; when the locking block 154 moves the locking housing 155 downward, the upper end portion of the locking housing 155 moves downward, with the lower end of the elastic disk 156 abutting the upper side wall of the sliding block 153;Since the angle between the elastic discs 156 and the outer wall of the upper end portion of the lock housing 155 is acute, the elastic disc 156 will bend and generate an elastic force, exerting an upward force on the lock housing 155, which in turn causes the lock block 154 to press against the lower side wall of the slide block 153. In this embodiment, the elastic disc is a plastic disc. The plastic disc has a certain degree of elasticity, and the two plastic discs and the lock housing 155 are integrally molded structures, and they are all made of plastic.

[0033] Specifically, in this embodiment, the locking portion includes locking teeth 158, and the upper side wall of the slide bar 152 is provided along its longitudinal direction with a plurality of locking slots 1521 that cooperate with the locking teeth 158. The locking housing 155 moves downward, the locking teeth 158 are fitted into the locking slot 1521, and the locking teeth 158 resist the inner groove wall of the locking slot 1521 to form a locking structure, so that the slide block 153 is unable to slide relative to the slide bar 152, and the slide bar 152 cannot move back and forth, and the backrest support 12 and the legrest 13 cannot adjust their angles. A plurality of locking slots 1521 are provided on the upper side wall of the slide bar 152 to form a rack-like structure, which is less costly compared to installing another rack on the upper side wall of the slide bar 152.

[0034] In this embodiment, due to the structure of the locking unit described above, when the entire chair frame is folded, the sliding block 153 can be slid relative to the sliding rod 152 to a point near the connection point between the armrest 151 and the legrest 13, and the connection point of the upper end portion of the base 11 and the armrest support 15 is located at the connection point of the armrest 151 and the legrest 13. In the folded state, the upper end of the base 11 is located at the front end of the armrest 151, and the rear end of the base 11 is located at the rear end of the seat frame 14, thereby further reducing the overall lateral volume in the folded state after folding.

[0035] As in Fig.13, this embodiment discloses a folding chair comprising a chair cloth 4 and a folding chair frame in any of the above embodiments, wherein the chair cloth 4 is mounted on a usable surface formed by the upper end surfaces of all three backrest supports 12, the seat frame 14 and the leg support 13.

[0036] The above embodiments are only the preferred embodiments of the invention, which cannot be used to limit the scope of the invention, and all non-essential changes and substitutions made by those skilled in the art based on the invention are included in the required scope of the invention.
