DETAILED DESCRIPTION

[0035] The utility model provides a sunshade awning locking device, comprising an axial connecting rod 1, a spring 2, a pipe clamp 3, a rotating part 4, a radial connecting rod 5 and a locking adjusting part 6.

[0036] The tube clamp 3 is provided with a tube clamp portion 31, a tube clamp locking slot 32, and a tube clamp hole 33 for the axial connecting rod 1 to pass through. The tube clamp portion can be an open U-shaped structure, which can allow a square tube or a round tube to be inserted therein. Since the back rod of the seat is generally a round tube, the tube clamp portion can be designed to be a structure for clamping a round tube. After the back rod of the seat is embedded in the tube clamp portion, the tube clamp portion has a certain elasticity, so that the back rod can be well interference-fixed in the tube clamp portion. Moreover, since most of the tube fittings of the awning are made of hollow materials and have a light overall weight, the tube clamp portion can also have a good clamping force when clamping the back rod. The tube clamp locking slot and the tube clamp portion can be isolated. The tube clamp 3 is provided with an inwardly concave circular platform, and the tube clamp locking slots are evenly distributed in the circular platform. The tube clamp locking slot can be a groove-shaped structure. After the rotating locking protrusion 41 is inserted into the tube clamp locking slot, it cannot be rotated anymore. The rotating member 4 must be pushed out of the tube clamp locking slot before it can be rotated again. The pipe clamp hole is a pipe clamp hole located at the center of the circular platform, which can accommodate the position of spring 2. Spring 2 can be in a compressed state when locked and in a normal state when unlocked. However, since the limiting outer teeth and the limiting inner teeth on the locking adjustment part have a limiting effect when they cooperate, spring 2 cannot achieve the function of automatic recovery. Spring 2 changes its compressed state after the position state of the locking adjustment part changes. The function of spring 2 is to make the locking adjustment part feel more compact when adjusted and the movement between parts more stable.

[0037] A rotation locking protrusion 41 is provided on one side of the rotating member 4, and a support foot 42 is provided on the other side. A limiting internal tooth is provided on the inner side of the support foot 42; a fixing structure for fixing the main pipe member of the awning is also provided on the rotating member 4. The rotating member 4 can be a cylindrical structure as a whole, and the shape of the rotation locking protrusion 41 matches the shape of the locking slot of the pipe clamp so that it can be normally embedded. The support foot 42 can be a U-shaped structure as a whole, and two support feet 42 are arranged for support; the limiting internal tooth can be a strip-shaped concave structure, so that a strip-shaped groove structure is formed on the surface, and the groove structure can cooperate with the protruding structure of the limiting external tooth to achieve a limiting effect. Preferably, the fixing structure 44 on the rotating member 4 is an inner hole, and after the main pipe member of the awning is inserted into the inner hole, the axial connecting pipe passes through the main pipe member of the awning to achieve fixation.

[0038] The axial connecting rod 1 passes through the pipe clamp 3, the rotating part 4 and the radial connecting rod 5 in sequence. One end of the axial connecting rod 1 has a baffle plate to limit one side of the pipe clamp 3. The other end of the axial connecting rod 1 is fixed on the radial connecting rod 5. The radial connecting rod 5 is provided with an internal screw hole, and the front end of the axial connecting rod 1 is provided with an external thread. The two are fixedly connected by threading. Of course, welding or pin fixing can also be used. The spring 2 is installed on the axial connecting rod 1; the axial connecting rod 1 is provided with a thin rod portion, and the spring 2 is nested on the thin rod portion 101. The thin rod portion and the spring 2 are in the pipe clamp hole.

[0039] The locking adjustment member 6 has a through hole 61 for the radial connection member to pass through. The eccentric portion 62 of the locking adjustment member is fixed in the space formed by the two supporting feet 42 through the radial connection member. The tail end of the locking adjustment member is the eccentric portion, and the eccentric portion is provided with a through hole. The outer periphery of the eccentric portion is provided with a limiting outer tooth 63 that cooperates with the limiting inner tooth 43. In the maximum unlocking position, the center of the through hole of the eccentric portion is closest to the platform where the limiting inner tooth is located. At this time, the gap between the rotating member 4 and the pipe clamp 3 reaches the maximum, and the gap between the rotating locking protrusion 41 and the pipe clamp locking slot between the two also reaches the maximum. Therefore, the two are separated at this time, and the rotating member 4 can rotate. In the locked state, the center of the through hole of the eccentric part is farthest from the platform where the limiting inner teeth are located, that is, the radial connecting rod 5 is also farthest from the rotating part 4. At this time, the gap between the rotating part 4 and the pipe clamp 3 is minimized, and the gap between the rotating locking protrusion 41 and the locking slot of the pipe clamp is also minimized. Therefore, at this time, the two are already engaged with each other, and the rotating part 4 cannot rotate. Therefore, the device can achieve locking and unlocking through the locking adjustment part. The eccentric part of the locking adjustment part has limiting outer teeth, and the outer surface of the rotating part 4 has limiting inner teeth. In the unlocked or locked state, the cooperation of the limiting inner teeth and the limiting outer teeth can keep the eccentric part stable in this state, and it is not easy to slide and cause locking or unlocking failure. At the same time, since the locking adjustment member needs to be operated when unlocking or locking, the locking adjustment member can also overcome the limiting force between the limiting inner teeth and the limiting outer teeth under the action of external force, and can also realize the adjustment of the limiting position. In addition, there is a spring 2 between the rotating member 4 and the pipe clamp 3, so that the eccentric part of the locking adjustment member can provide a certain elastic force during the rotation process, that is, when changing the locking state.

[0040] The utility model is optimized, and after the plane where the rotating locking protrusion 41 is located is embedded in the circular platform, the rotating locking protrusion 41 cooperates with the locking slot of the pipe clamp, and a guide column 45 with a protruding hole is also provided on the plane where the rotating locking protrusion 41 is located. The guide column is inserted into the hole of the pipe clamp, and the axial connecting rod 1 passes through the guide column.

[0041] The utility model also discloses a sunshade, comprising a main pipe 7, a shielding pipe 8 and a sliding pipe 9. A sunshade locking device is installed on the main pipe 7. The main pipe 7 is inserted into a fixing structure 44 of the sunshade locking device. A tarpaulin is arranged on the shielding pipe to achieve a sunshade effect. One end of the sliding pipe is movably connected to the shielding pipe, and the other end of the sliding pipe is connected to the main pipe through the sliding locking device. The upper end of the main pipe is movably connected to the rear end of the shielding pipe.

[0042] The main pipe, the shielding pipe and the sliding pipe can all use round tubes. When the sunshade is unfolded, the main pipe and the shielding pipe can be at a 7-shaped angle, or can be adjusted to other angles. A sunshade locking device is installed at the lower end of the main pipe, so that the entire sunshade can be directly fixed on the back rod of the seat by snapping.

[0043] The sunshade locking device comprises an axial connecting rod 1, a spring 2, a pipe clamp 3, a rotating member 4, a radial connecting rod 5 and a locking adjustment member. The pipe clamp 3 is provided with a pipe clamp portion, a pipe clamp locking slot and a pipe clamp hole for the axial connecting rod 1 to pass through. A rotating member 4 is provided with a rotating locking protrusion 41 on one side and a supporting foot 42 on the other side. The inner side of the supporting foot 42 is provided with a limiting internal tooth; the rotating member 4 is also provided with a fixing structure for fixing the main pipe member of the sunshade. The axial connecting rod 1 passes through the pipe clamp 3, the rotating member 4 and the radial connecting rod 5 in sequence, one end of the axial connecting rod 1 is limited to one side of the pipe clamp 3, and the other end is fixed to the radial connecting rod 5. The spring 2 is installed on the axial connecting rod 1; the locking adjustment piece is provided with a through hole for the radial connecting piece to pass through, and the locking adjustment piece is fixed in the space formed by the supporting foot 42 through the radial connecting piece. The tail end of the locking adjustment piece is an eccentric part, a through hole is provided on the eccentric part, and a limiting external tooth cooperating with the limiting internal tooth is provided on the outer periphery of the eccentric part.

[0044] Preferably, the upper end of the main pipe is movably connected to a swing rod 11 through a pin, and the other end of the swing rod 11 is connected to the rear end of the shielding pipe through a pin to realize the movable connection between the main pipe and the shielding pipe.

[0045] The preferred embodiment of the utility model comprises a sliding locking device 10 of a sliding member 12, an axle rod 13, a radial rod 14 and a sliding adjusting member 15. The sliding member is provided with a through hole 121 for clamping the main pipe member and a sliding clamping portion 122 arranged outside the through hole 121; the sliding member is provided with two columns 123, the radial rod is installed between the columns, and a limited internal tooth 124 is arranged between the two columns. The axle rod passes through the sliding clamping portion 122 of the sliding member and then is connected with the radial rod to fix the radial rod on the column. The tail end of the sliding adjusting member is an eccentric portion, a through hole is arranged on the eccentric portion, the radial rod passes through the through hole, and a limited external tooth 152 cooperating with the limited internal tooth is arranged on the outer periphery of the eccentric portion 151. When locking, the through hole of the eccentric portion is the farthest from the sliding clamping portion. At this time, the radial rod will pull the cross bar to make the two sliding clamping portions close to each other, so that the distance between the two sliding clamping portions is reduced, thereby making the main pipe member clamped more stably inside the through hole 121. When unlocking, the distance between the radial rod and the sliding clamping part is reduced, and the two sliding clamping parts will naturally separate when no external force is applied, and the clamping force is reduced, so that the main pipe can slide in the through hole 121. The working principle and structure of the sliding locking device of the utility model are the same or similar to those of the sunshade locking device, and both realize loosening or locking through different positions of the eccentric part.

[0046] Although the specific implementation of the utility model is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
