Description

Portable umbrella fixing device

Technical Field

The invention belongs to the field of umbrella fixing devices, in particular to a portable fixing device for large-sized umbrellas and eccentric umbrellas on hardened ground.

Background

In engineering measurement, outdoor exercises, standing post and other production and living, umbrella is often used, and the umbrella cover is generally large in order to obtain a large working or activity space. The large umbrella is fixed in a common counterweight or ground insertion mode because of the large umbrella cover and the large umbrella body weight, and the large acting force required for stabilizing the umbrella body. The counterweight is generally heavy and is not suitable for moving; the ground insertion fixation has high requirements on the field, the hardened ground cannot be used, the too weak soil ground cannot be used, and the capsizing easily occurs; the eccentric umbrella is generally used in a mode of directly fixedly connecting to the ground because the gravity center is not at the position of the umbrella handle, and cannot move. And the movable sites such as engineering measurement are not fixed, the site conditions are not fixed, and the large umbrella and the eccentric umbrella are difficult to use.

The aim of the invention is realized by the following technical scheme:

the portable umbrella fixing device is characterized by comprising a central sleeve, a plurality of horizontal cross bars, a plurality of steerable cross bars, a central grounding fixing piece and a remote grounding fixing piece, wherein the horizontal cross bars are arranged in a stacked mode and sleeved on the central sleeve and can rotate around the central sleeve, the horizontal cross bars are rotatably connected with the steerable cross bars, the central grounding fixing piece is arranged at the lower part of the horizontal cross bars and sleeved on the central sleeve, and the remote grounding fixing piece is rotatably connected with the steerable cross bars; the horizontal cross rod can rotate around the central sleeve in parallel with the ground, and the steerable cross rod and the far-end grounding fixing piece can both rotate perpendicular to the ground to form a central fixing point and a plurality of far-end fixing points.

Further, the central grounding fixing piece is a ground plug or a sucker.

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

Further, the distal grounding fixing member is connected with the steerable cross bar through an end connecting member and an end connecting screw member, the sleeve end of the end connecting member is fixedly connected with the distal grounding fixing member, and the other end of the end connecting member is connected with the steerable cross bar through the end connecting screw member.

Further, the horizontal cross rod and the steerable cross rod are spirally fixed through the cross rod connection.

Further, the number of the horizontal cross bars and the number of the steerable cross bars are three, and each horizontal cross bar is connected with one steerable cross bar.

Further, the horizontal cross rod and the steerable cross rod are hollow round rods.

The beneficial effects of the invention are as follows:

(1) The two fixing modes of center fixing and far-end fixing can be replaced according to the field type, and the hardened ground and the soil ground are applicable;

(2) The portability is strong. The distal end point increases the overturning moment through increasing the moment arm, so that the weight of the fixing device is reduced, and the movement is convenient; the cross rod is folded to fold the device into a V shape, and the device is convenient to carry.

(3) The transverse rods can be unfolded to form any angle, and the steerable transverse rods can rotate in the vertical plane, so that the novel multifunctional steering wheel is suitable for different terrains.

Detailed Description

The objects and effects of the present invention will become more apparent from the following detailed description of the preferred embodiments and the accompanying drawings, in which the present invention is further described in detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

As shown in figures 1-7, the portable umbrella fixing device is provided with four fixing points in total, wherein the four fixing points comprise a central fixing point below the umbrella handle and three far-end fixing points. The umbrella lower center fixed point is connected with the umbrella handle 5 through the upper end of the center sleeve 6, and the lower end of the center sleeve 6 is connected with the center sucker 14-1 or the center ground plug 15-1. The umbrella handle 5 is connected with the central sleeve 6 in a socket joint mode and is fixed by the umbrella handle fixing screw 7. The far-end fixed point is connected with the central sleeve 6 through the horizontal cross bars 8-1, 8-2, 8-3 and the steerable cross bar 9; the upper, middle and lower layers of the horizontal cross bars 8-1, 8-2 and 8-3 are sleeved into the central sleeve 6 in sequence, and then the horizontal cross bars are screwed into the cross bar fixing screw 13 for fixing; the horizontal cross bars 8-1, 8-2 and 8-3 and the steerable cross bar 9 are fixed through a cross bar connecting screw 10; the distal fixed point end suction cup 14-2 or the end ground insert 15-2 is bolted to the end connector 11, and the end connector 11 is fixed to the steerable rod 9 with the end connection screw 12.

The umbrella fixing device is fixed with the ground in two ways, the sucker 14 is suitable for hardening the ground, and when in use, vaseline dry ground or plasticine wet ground is smeared at the fixed point, and the sucker is pressed on the ground; the ground plug 15 is suitable for soil, directly extrudes and pierces soil, the central ground plug 15-1 adopts a gate shape to strengthen anchoring force, the end ground plug 15-2 adopts a straight shape, and the end is provided with threads to be connected with the central sleeve 6 and the end connecting piece 11.

Four points are fixed, and three points at the far end improve the overturning moment through increasing the moment arm, so that the weight of the fixing device is reduced, and the movement is convenient. The horizontal directions of the three cross bars can be adjusted to form different included angles so as to adapt to the limitation of the horizontal position of the field; the position of the steerable cross rod in the vertical plane can be adjusted to adapt to the situation of the height fluctuation of the field; the steerable cross bar can be disconnected, and the end connecting piece is directly fixed on the horizontal cross bar so as to adapt to the limitation of space; the end connector can be rotated to ensure that the ground insert is perpendicular to the ground or the sucker is always in a close fit state with the ground.
