Description

A portable umbrella fixing device

Technical field

The invention belongs to the field of umbrella fixing devices, especially portable fixing devices for large umbrellas and eccentric umbrellas on hardened ground.

Background technique

Umbrellas are often used in production and life such as engineering surveying, outdoor sports, and guard duty. In order to obtain a larger space for work or activities, the umbrella surface is generally larger. Large umbrellas require a large force to stabilize the umbrella due to their large surface and heavy weight, so they are often fixed with counterweights or ground inserts. Counterweights generally have a large weight and are not suitable for mobile use; ground-mounted fixing requires high site requirements and cannot be used on hardened ground, nor can it be used on soil that is too soft, and is prone to overturning; eccentric umbrellas are generally used because the center of gravity is not at the handle. It is used directly fixed to the ground and cannot be moved. However, the location of activities such as engineering surveying is not fixed, and the site conditions are not fixed. It is difficult to use large umbrellas and eccentric umbrellas.

Contents of the invention

In view of the shortcomings of the existing technology, the present invention provides an umbrella fixing device that has a simple structure, is easy to carry, is simple to operate, and is suitable for various ground conditions.

The purpose of the present invention is achieved through the following technical solutions:

A portable umbrella fixing device, which is characterized in that the device specifically includes a central sleeve, a plurality of horizontal crossbars, a plurality of steerable crossbars, a central grounding fixture, a distal grounding fixture, and a plurality of horizontal horizontal rods. The cross bars are arranged in a stack, and are all sleeved on the central sleeve, and can rotate around the center sleeve. The horizontal cross bars are rotatably connected to the steerable cross bars, and the center is grounded. The fixing piece is arranged at the lower part of the horizontal cross bar and is also sleeved on the central sleeve. The distal grounding fixing piece is rotatably connected to the steerable cross bar; the horizontal cross bar The center sleeve can be rotated parallel to the ground, and both the steerable crossbar and the distal grounding fixture can be rotated perpendicular to the ground to form a central fixed point and several distal fixed points.

Further, the central grounding fixture is a ground plug or a suction cup.

Further, the distal grounding fixture is a ground plug or a suction cup.

Further, the distal grounding fixture is connected to the steerable crossbar through an end connector and an end connecting screw, and the sleeve end of the end connector is connected to the distal grounding member. The fixing piece is fixedly connected, and the other end is connected to the steerable crossbar through the end connecting screw piece.

Further, the horizontal crossbar and the steerable crossbar are screw-fastened through the crossbar connection.

Further, there are three horizontal crossbars and three steerable crossbars, and each horizontal crossbar is connected to one steerable crossbar.

Furthermore, the horizontal crossbar and the steerable crossbar are both hollow round bars.

The beneficial effects of the present invention are as follows:

(1) The two fixing methods of the present invention, the central fixation and the distal fixation, can be replaced according to the type of site, and are suitable for both hardened ground and soil ground;

(2) High portability. The far end point increases the overturning moment by increasing the force arm, which reduces the weight of the fixed device and makes it easy to move; after folding the crossbar, the device is folded into a V shape, making it easy to carry.

(3) Several crossbars can be deployed at any angle, and the steerable crossbars can rotate in the vertical plane, making them suitable for different terrains.

Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The purpose and effects of the present invention will become clearer. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

As shown in Figure 1-7, a portable umbrella fixing device is provided with four fixing points, including a central fixing point under the umbrella handle and three distal fixing points. The central fixed point under the umbrella is connected to the umbrella handle 5 through the upper end of the central sleeve 6, and the lower end of the central sleeve 6 is connected to the central suction cup 14-1 or the central ground plug 15-1. The umbrella handle 5 is connected to the central sleeve 6 in a socket manner and is fixed by the umbrella handle fixing screw 7 . The distal fixed point is connected to the central sleeve 6 through horizontal crossbars 8-1, 8-2, 8-3 and steerable crossbar 9; horizontal crossbars 8-1, 8-2, 8-3 are divided into The upper, middle and lower layers are inserted into the center sleeve 6 in turn, and then screwed into the crossbar fixing screw 13 to fix it; the horizontal crossbars 8-1, 8-2, 8-3 and the steerable crossbar 9 are fixed by the crossbar connecting screw 10 ; The distal fixed point end suction cup 14-2 or the end ground plug 15-2 is bolted to the end connector 11, and the end connector 11 and the steerable rod 9 are fixed with the end connection screw 12.

The umbrella fixing device is fixed to the ground in two ways. The suction cup 14 is suitable for hardened ground. When in use, apply Vaseline on dry ground or plasticine on wet ground at a fixed point, and press the suction cup on it; the ground plug 15 is suitable for soil sites. , directly squeezed and penetrated into the soil. The center ground plug 15-1 adopts a door type to enhance the anchoring force. The end ground plug 15-2 adopts a straight shape, and the end is provided with threads, a central sleeve 6 and an end connector. 11 connections.

Four-point fixation, the three distal points increase the overturning moment by increasing the force arm, reducing the weight of the fixation device and making it easy to move. The horizontal orientation of the three crossbars can be adjusted to form different angles to adapt to the horizontal position restrictions of the site; the position of the steerable crossbar in the vertical plane can be adjusted to adapt to the ups and downs of the site; the steerable crossbar does not need to be connected. The end connector is directly fixed on the horizontal crossbar to adapt to space limitations; the end connector can be rotated to ensure that the ground is inserted into the vertical ground or the suction cup and the ground are always in a tight fit. When not in use, the crossbar connecting screw and the crossbar connecting screw can be loosened, and the folded crossbar can be folded into a V shape for easy portability.

In order to further enhance the portability of the device, the transverse rods are hollow round rods to reduce mass. The material is generally steel, which has low cost, high strength and good durability.
