Description

Deck chair with angle limiting function Technical Field The utility model relates to a deck chair with angle limiting function. Background In the prior art, in order to realize the adjustment of the backrest angle, some reclining chairs adopt the following common reclining chair structure, which comprises a bracket, a backrest, a seat, a sliding pipe sleeve and a connecting rod, wherein the middle lower part of the backrest is rotationally connected with the bracket, the rear end of the seat is rotationally connected with the lower end of the backrest, the front end of the seat is rotationally connected with one end of the connecting rod, the sliding pipe sleeve is fixedly arranged on the bracket, and the other end of the connecting rod is slidingly and telescopically arranged in the sliding pipe sleeve. In order to lock the angular position of the backrest and facilitate the adjustment operation of a user, a locking rod is usually arranged on the side wall of the sliding sleeve in a threaded connection manner, and the end part of the locking rod is used for pushing the connecting rod tightly to prevent the connecting rod from moving relative to the sliding sleeve. However, in actual use, when the user needs to switch from the lying state to the sitting state to leave the reclining chair, the locking lever is unlocked first, then the user bends over to tilt the center of gravity of the body forward, and then leaves the reclining chair. After the user leaves the deck chair, as the locking rod does not act on the connecting rod any more, the connecting rod can slide freely relative to the sliding pipe sleeve, the backrest can form a gravity moment for driving the backrest to rotate backwards, so that the deck chair is in a lying state when not used, the floor area is large, the storage is inconvenient, and when the user sits on the seat again, the backrest can rotate forwards rapidly and impact the back of the user forcefully, so that bad use experience is formed. Disclosure of utility model In order to overcome the defects in the prior art, one of the purposes of the utility model is to provide a reclining chair with angle limiting, which maintains a backrest at a sitting angle when the reclining chair is not in use so as to reduce the storage area, and can smoothly adjust the angle position of the backrest when a human body sits on the chair. The reclining chair with the angle limiting function comprises a support, a sliding pipe sleeve, a backrest, a seat, a connecting rod and an automatic limiting mechanism, wherein one end of the sliding pipe sleeve is fixedly arranged on the support, the other end of the sliding pipe sleeve extends forwards in an inclined mode, the middle lower portion of the backrest is rotatably connected with the support, the rear end of the seat is rotatably connected with the lower end of the backrest, the front end of the seat is pivoted with the connecting rod, one end, far away from the seat, of the connecting rod is slidably inserted into the sliding pipe sleeve, the automatic limiting mechanism is arranged between the connecting rod and the sliding pipe sleeve, the gravity moment of the backrest acting on the support can be overcome to stabilize the angle position of the backrest, and the connecting rod can be unlocked to freely slide relative to the sliding pipe sleeve when the seat is pressed. The reclining chair with angle limiting according to the embodiment of the utility model at least comprises the following components The beneficial effects are that: The angle limiting deck chair with the structure is characterized in that an automatic limiting mechanism is arranged between the connecting rod and the sliding pipe sleeve, and can overcome the gravity moment of the backrest acting on the support, so that the backrest is maintained at a sitting angle to reduce the storage area when the deck chair is not used, and the automatic limiting mechanism can be unlocked when a user sits on the chair, so that the connecting rod can slide freely relative to the sliding pipe sleeve, and the angle position of the backrest can be adjusted smoothly. In some embodiments of the present utility model, the automatic limiting mechanism includes a limiting member that is telescopically movable along a radial direction of the sliding sleeve, and an elastic member that urges the limiting member to move inward along the radial direction of the sliding sleeve to abut against an outer peripheral wall of the link, and when the seat is pressed, the link is driven to be inserted into the sliding sleeve and the limiting member is urged to return and compress the elastic member. In some embodiments of the present utility model, a sleeve matching the diameter of the connecting rod is disposed inside the end of the sliding sleeve, a notch is disposed on the side wall of the sleeve, the limiting member is a swing arm connected with the sleeve and located in the notch, a mounting gap is disposed between th
