The invention provides a rocker mechanism which comprises a first rod (10), an operation shaft (20), a connector (30) and a hollow second rod (40). The connector (30) is connected with the first rod (10) and the operation shaft (20), the second rod (40) sleeves the first rod (10) and is elastically connected with the first rod (10), and a first end (45) of the second rod (40) sleeves the operation shaft (20). When lifting force is applied to the second rod (40), the second rod (40) breaks away from the operation shaft (20), and the first rod (10) and the second rod (40) can be folded relative to the operation shaft (20). The first rod of the rocker mechanism is folded around the operation shaft, a user conveniently folds the first rod when not using a rocker, the folded rocker is small in occupied space and convenient to store, and operation precision can be ensured. The invention further provides a remote controller.

The invention provides an angle material for wall surface decoration and a manufacturing method of the angle material in order to carry out good construction on a corner portion of an external angle portion or an internal angle portion. The angle material for the wall surface decoration is folded to form an angle which corresponds to the angle of the corner portion of the external angle portion or the internal angle portion, the angle portion of the folded angle material for the wall surface decoration keeps consistent with the angle portion of the corner portion, when the angle material is adhered to the wall surface of the corner portion, an operator can determine whether the angle material for the wall surface decoration is tightly adhered to the wall surface of the corner portion in a visual mode through the surface side of the transparent angle material for the wall surface decoration, and when the operator finds that the effect of adhesion is poor, the angle material for the wall surface decoration is corrected to be tightly adhered to the wall surface of the corner portion. The angle material for the wall surface decoration and the manufacturing method of the angle material have the advantages that a wall cloth material can be well adhered along the corner portion through the angle material for the wall surface decoration, and meanwhile the corner portion can be finely reconditioned to be in a good state.

The invention discloses a foldable bed guardrail, which relates to a baby article installed on the side of the bed to prevent babies from rolling and falling while sleeping on the bed. It is composed of foot rods, etc., and the disclosed technical feature is that the ejector rods are designed as left and right ejector rods, and the middle rod is also designed as left and right middle rods, and then a fixed-angle rotation is added on the left connecting rod and the right connecting rod respectively. Installed left foot bar and right foot bar; at the same time, between the adjacent ends of the left and right push rods, left and right middle bars and left and right foot bars, upper rotation points and middle rotation points that can be used for synchronous linkage rotation are respectively set. point and the lower turning point, so through the above structural design, only one of the turning points can be operated to conveniently and flexibly expand or fold the bed guardrail, and the whole bed guardrail also has the advantages of simple structural design, stable and reliable use, and small folding volume. It greatly facilitates packaging and transportation, and also facilitates consumers' storage and storage.

The invention belongs to the technical field of buildings, and particularly relates to a folding-type yurt. The folding-type yurt comprises a middle vertical column, supporting feet, a fixed seat, outer side vertical columns, an umbrella supporting frame, an inclined supporting frame, a cross rod and a top supporting frame; one end of each supporting foot is hinged to the bottom of the middle vertical column, and the other end of each supporting foot is hinged to the bottom of the corresponding outer side vertical column; the tops of the outer side vertical columns are hinged to the end, provided with connecting plates, of a supporting flat plate; the other end of the supporting flat plate is hinged to the inclined supporting frame, the umbrella supporting frame is further hinged to the other end of the inclined supporting frame, and the end, provided with the connecting plates, of the supporting flat plate is simultaneously hinged to the cross rod and the free end of a vertical columnof the top supporting frame; the other end of the cross rod and the free end of a supporting rod of the top supporting frame are hinged to the upper portion of the middle vertical column; and the fixed seat is fixed between the two outer side vertical columns. The yurt can be flexibly folded, the folded yurt is conveniently transported, the relatively heavy fixing form of a former yurt is changed, and migration is convenient.
