When the traditional sunshade is installed, the steel frame is often fixed on the ground firstly, and then the shed plate is welded and fixed on the steel frame, so that the installation process of the sunshade is inconvenient and needs to be improved.

Disclosure of Invention

The invention aims to provide a sunshade which has the effect of convenient installation.

The technical purpose of the invention is realized by the following technical scheme: a sunshade comprises a support and a shed roof arranged on the support, wherein a plurality of supporting rods are vertically arranged above the support, mounting rods positioned above the supporting rods are arranged on the shed roof, and self-locking mechanisms locked with each other are arranged between the supporting rods and the mounting rods; the self-locking mechanism comprises a locking plate arranged on the lower end face of the mounting rod, first racks are vertically arranged on two sides of the locking plate, and a locking groove for the sliding embedding of the locking plate and the first racks is formed in the upper end face of the supporting rod; the outer wall of the supporting rod is vertically and slidably connected with a sliding sleeve used for sleeving the outer wall of the mounting rod, grooves are formed in the inner walls of the two sides of the sliding sleeve, and a second rack is vertically arranged in each groove; two sides of the supporting rod are respectively provided with a connecting groove for communicating the locking groove and the groove, a gear is rotationally connected in the connecting groove, and the gear is meshed with the first rack and the second rack; the upper end outer wall of installation pole evenly is provided with a plurality of elasticity fixture blocks, the upper end inner wall of sliding sleeve is provided with a plurality of confession the draw-in groove of elasticity fixture block embedding.

Through adopting above-mentioned technical scheme, when the installation used above-mentioned sunshade, be fixed in ground with the support, then hoist the shed roof to make the locking groove on the locking plate grafting bracing piece of terminal surface under the installation pole. At the moment, the locking plate drives the first rack to move synchronously, when the lower end of the first rack is meshed with the gear, the first rack drives the gear to rotate, the gear drives the second rack to move upwards, the second rack drives the whole sliding sleeve to move upwards, and the sliding sleeve is gradually sleeved on the outer wall of the mounting rod. When lockplate pegging graft in the locking groove completely, the sliding sleeve cladding is in the junction of bracing piece and installation pole, and in the elasticity fixture block embedding draw-in groove simultaneously, and then realize the locking of bracing piece, installation pole and sliding sleeve fixed, realize the auto-lock of support and shed top simultaneously. Therefore, the self-locking mechanism capable of automatically locking and fixing is arranged, the supporting rod and the mounting rod are locked and fixed, namely the self-locking of the support and the shed top is fixed, so that the support and the shed top are assembled more easily and conveniently, and the effect of convenience in mounting is achieved.

The invention is further provided with: the elasticity fixture block includes the block of rectangular shape, the outer wall setting of installation pole holds the holding tank of block, the lower extreme of block articulate in the diapire of holding tank, the diapire of holding tank is provided with and is used for contradicting the fixed block of block lower extreme outer wall, and the upper end inner wall of block with be provided with the spring between the upper end lateral wall of holding tank still.

Through adopting above-mentioned technical scheme, when the sliding sleeve upward movement, the sliding sleeve inner wall pressure moves the upwards upset of block, and this moment the block pressure moves in the spring compression and imbeds the holding tank gradually. When the locking groove is completely inserted into the locking plate, the block body is aligned to the clamping groove, the spring is bounced open and drives the block body to turn outwards, and the driving block is gradually embedded into the clamping groove. When the block is embedded into the clamping groove and is abutted against the fixing block, the upper end of the block is inclined towards the upper part, so that the limiting fixation among the supporting rod, the mounting rod and the sliding sleeve is realized.
