Plastic umbrella jump convenient to install

Abstract

A plastic umbrella jump convenient to install relates to the technical field of umbrellas, is suitable for straight-rod umbrellas and umbrella rods made of wood rods, bamboo rods, plastic rods, metal rods and the like, and is composed of a frame, elastic pieces, barbs, limiters, protrusions, buttons and hinges. The umbrella jump is formed by plastic with good elasticity and toughness in an injection molding mode, and in order to simplify the production process and facilitate installation on the umbrella rod, all the components are connected together in the injection molding process. Before installation, the protrusion at the upper end of the button of the umbrella jump is placed in the limiting stopper, and a long round hole with the appropriate size is punched in the umbrella rod; during installation, the umbrella jump is integrally pressed into the inner hole of the umbrella rod, and the umbrella jump is firmly embedded into the inner hole of the umbrella rod under the action of the barbs. The lower end of the button is connected with the frame through an integrated hinge, so that the button is flexible in action and can bear pressure generated when the umbrella is unfolded, and the service life can reach thousands of times. When the umbrella is opened, the umbrella support is pushed to move upwards along the umbrella rod, the umbrella jump button is pressed into the umbrella rod through the inner hole wall of the umbrella support, after the umbrella support is in place, the pressure of the umbrella support on the umbrella jump button disappears, the button is reset under the action of the internal elastic piece, and the umbrella jump hooks the umbrella support; when the umbrella is folded, the button is pressed to enter the umbrella rod, the umbrella support descends, and the button is reset again. The invention has the advantages of low cost, simple and quick installation, attractive appearance, durability and wide application range.

Description

Technical Field

[0001] The invention belongs to the technical field of umbrellas, in particular to a plastic umbrella that is easy to install. Background Art

[0002] There are several existing methods for manufacturing and installing parachute rigs: One method involves having a hardware factory produce them from sheet metal using spring wire, then punching holes or slotting them into the pole; another involves using metal sheets with springs or spring sheets, then punching holes and riveting them into the pole; and a more traditional method involves cutting bamboo rigs into bamboo rigs and inserting them into the pole. The corresponding punching equipment is also complex, and the rigs are entirely handmade. All of these methods share a common drawback: high material or labor costs, or both. These methods require high skills, skilled workers, and equipment, resulting in low production efficiency. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned shortcomings of the prior art and proposes solutions from the following aspects.

[0004] The parachute jump is made of plastic with good elasticity (PA, PC, PP, PS, etc.) by injection molding to reduce production costs. The corresponding oblong holes are punched on the umbrella pole.

[0005] The frame serves as the skeleton and foundation of the entire parachute jump. Its overall thickness (excluding the barbs) is smaller than the inner width of the oblong hole in the umbrella pole, making it easy to install and ensuring the flexible movement of the shrapnel and button.

[0006] Before installation, place the button inside the frame, and the protrusion on its upper end restricts its movement within the frame, thereby ensuring normal use of the button; during installation, press the parachute into the oblong hole of the umbrella pole until the barb is immersed in the umbrella pole; after installation, the outer part of the button frame is exposed to the umbrella pole, which is convenient for use.

[0007] The spring is pressed against the button, providing the button with power to reset.

[0008] The hinge connects the button and the frame and is the axis of rotation of the button. It is a typical plastic integrated hinge.

[0009] The barbs are provided to form a tight fit with the inner hole of the umbrella pole, and the one-way shape has the characteristics of easy entry and difficult exit, so it will not loosen during use.

[0010] This invention primarily addresses cost and efficiency issues on the production side, and therefore remains essentially identical in appearance and operation to traditional parachuting systems. During deployment, the support rises along the shaft and passes through the ramp. The inner wall of the support compresses the button and internal spring. After the support passes the jump, the button returns to its original position, absorbing the pressure on the support. During retraction, pressing the button causes the support to descend. After the support passes the jump, the button returns to its original position.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The parachute jump is made of one-piece injection molding, which is smooth to use, durable and has low overall cost.

[0013] It has strong applicability and is applicable not only to umbrella poles of various specifications such as wooden poles, plastic poles, and metal poles, but also to irregular umbrella poles such as bamboo poles.

[0014] Compared with existing equipment, the umbrella pole punching machine is simpler and only needs to punch an oblong hole of appropriate size along the axis of the umbrella pole through the axis.

[0015] The installation is very simple. First, place the button into the frame, and then press the frame into the umbrella pole. The process is simpler and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 、 2 These are the schematic diagrams before and after the parachute jump installation. Figure 3 、 4 , 5 are the positive, front and top views respectively.

[0017] Description of the accompanying drawings: frame 1, spring piece 2, barb 3, limiter 4, protrusion 5, button 6, hinge 7. DETAILED DESCRIPTION

[0018] The purpose of the present invention is to facilitate the production and installation of a parachute jumper. The technical solution is now described in detail as follows in conjunction with the figures in the embodiments.

[0019] Parachute jump is made of plastic with good elasticity (PA, PC, PP, PS, etc.) by injection molding, which reduces production costs.

[0020] like Figure 1 、 Figure 2 As shown, the frame 1 is the skeleton and foundation of the entire parachute jump, and the spring clip 2 provides the elastic force for the button 6 to return to its original position. Its overall thickness (excluding the barbs 3) is less than the inner width of the oblong hole in the umbrella pole, which facilitates installation and ensures the flexible movement of the spring clip 2 and button 6.

[0021] Before installation, the button 6 is placed inside the frame 1, and the upper end protrusion 5 is restricted in movement within the limiter 4 and the frame 1, thereby ensuring that the button 6 is easy to use; during installation, the entire umbrella jump is pressed into the oblong hole of the umbrella pole until the barb 3 is immersed in the umbrella pole. At this time, the outer part of the frame 1 of the button 6 is exposed to the umbrella pole, which is convenient for operation.

[0022] The hinge 7 connects the button 6 and the frame 1 and is also the axis of rotation of the button 6. It is a typical plastic integrated hinge.

[0023] The outer diameter of the barb 3 should be slightly larger than the inner width of the umbrella pole, so that it can form a tight fit with the inner hole of the umbrella pole, and the one-way shape has the characteristics of easy entry and difficult exit, so it will not loosen during use.

[0024] The present invention is described by way of examples, which are not exhaustive and do not limit the present invention to the specific embodiments described. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
