Description

Technical Field

[0001] The utility model relates to the field of sunshades, in particular to a connection structure between an end cover and a push rod. Background Art

[0002] Several groups of blinds are arranged on the awning. In order to ensure the linkage flipping between the groups of blinds, end covers are set on both sides of the blinds. The end covers on the same side are hinged to a push rod, and the push rod is controlled by controlling the driving assembly on the awning, so that the blinds can be flipped synchronously.

[0003] In this structure, the traditional end cover side and push rod are both flat, and the end cover and the push rod side are in close contact. When the push rod is moving, the two sides are directly rubbed against each other, and the friction area is large. This not only increases the convenience of operation, but also reduces the lifespan due to wear.

[0004] The existing structure is improved by arranging a sliding plate between the end cover and the push rod. Although this can reduce friction to a certain extent, it is still inconvenient because the friction contact surface is still large and the sliding plate needs to be replaced regularly. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a connection structure between an end cover and a push rod, which can effectively solve the problems existing in the above-mentioned traditional awnings.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a connection structure between an end cover and a push rod, the end covers are arranged laterally and evenly on the end face of the push rod in the length direction, a protrusion with a contact area smaller than the side surface of the end cover is arranged on the end cover and located on one side of the push rod, a connecting piece is provided that passes through the protrusion and is embedded in the push rod, so that the end cover is rotatably arranged on the push rod.

[0007] In the above technical solution, further, a recessed portion is provided on the end cover and located on the opposite side of the push rod, behind the protruding portion, and the connecting member enters from the direction of the recessed portion and extends from the direction of the protruding portion.

[0008] In the above technical solution, further, the connecting part of the connecting piece is composed of two sections, including a threaded part located at the end and a smooth part located at the head end, the threaded part is screwed into the push rod, and the smooth part is located in the end cover.

[0009] In the above technical solution, further, a step is formed in the recessed portion, and the connecting member is abutted against the step.

[0010] In the above technical solution, the end cover includes a base and a convex portion located above the base, and a riveting shaft installed in a flip sleeve is provided on the convex portion and located on one side of the push rod. The convex portion is located on the base and at the end position on one side of the push rod.

[0011] In the above technical solution, further, a link plate is provided on the push rod, and a driving assembly is provided to be connected to the link plate, the driving assembly includes a driving shaft, a first connecting rod, and a second connecting rod, one end of the first connecting rod is fixed to the end of the driving shaft, and both ends of the second connecting rod are respectively rotatably provided on the first connecting rod and the link plate.

[0012] The beneficial effects of the utility model are as follows: under the premise of ensuring the original functions, a protrusion with a smaller area is arranged on the end cover, thereby reducing the contact area between the end cover and the push rod, increasing the convenience of operation, reducing friction, and increasing the service life.

DETAILED DESCRIPTION

[0022] Reference Figure 1-7As shown, a connection structure between an end cover 1 and a push rod 2 is provided, wherein the end cover 1 is evenly arranged laterally on the end face of the push rod 2 in the length direction, a protrusion 3 with a contact area smaller than that of the side surface of the end cover 1 is provided on the end cover 1 and located on one side of the push rod 2, and a connecting piece 4 is provided which passes through the protrusion 3 and is embedded in the push rod 2, so that the end cover 1 is rotatably set on the push rod 2.

[0023] Among them, reference Figure 1-2 As shown, this connection structure is installed at the side of the awning, and the movement of the push rod 2 controls the synchronous rotation of several groups of end covers 1, so that the shutters on the awning are turned over.

[0024] Among them, Figure 7 As shown, the left side is the connecting member 4, the right side end cover 1 is attached to the side of the push rod 2, and the mounting holes thereon are aligned with each other, and a recessed portion 5 is provided behind the protrusion 3 and on the opposite side of the push rod 2, thereby forming a step 6 in the recessed portion 5, and the connecting member 4 enters from the direction of the recessed portion 5 and extends from the direction of the protrusion 3, and is restricted by the step 6, so that the connecting member 4 is restricted in the recessed portion 5.

[0025] The connecting part shown in the figure is a plug screw, including a threaded part 41 at the end and a smooth part 42 at the head end, and an end head with a diameter larger than the screw body is provided on the left side. When the connecting member 4 is fully installed, the threaded part 41 is screwed into the push rod 2, the smooth part 42 is located in the end cover 1, and the end head on the connecting member 4 rests on the step 6.

[0026] Among them, Figure 3-5 As shown, in order to ensure the flipping of the end cover 1, the end cover 1 includes a base 11 and a protrusion 12 arranged on the base 11, the protrusion 12 is not located at the center of the base 11, and a riveting shaft 8 installed in the flip sleeve 7 is arranged on the side of the protrusion 12 and located on one side of the push rod 2. The flip sleeve 7 is in a fixed state, and the end cover 1 rotates with the riveting shaft 8 as a rotation fulcrum. The protrusion 3 is located on the base 11 and at the end position (long side) on one side of the push rod 2. By pulling the push rod 2, each group of the end covers 1 rotate synchronously with their own riveting shaft 8 as a rotation fulcrum.
