Specific embodiment

It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality The feature applied in example can be combined with each other.

Many details are explained in the following description in order to fully understand the utility model, still, this is practical Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below The limitation of the specific embodiment of specification.

Embodiment 1, as shown in Figure 1, Figure 2, Figure 3 shows, short time consumption is long when the present embodiment aims to solve the problem that the connection of existing earth brace The technical issues of, for this purpose, the earth brace provided in this embodiment with quick-inserting structure, including upper earth brace and lower ground connection Bar, the bottom of upper earth brace be provided with insertion protrusion, be inserted into protrusion global shape be also it is cylindric, diameter is less than The diameter of earth brace is provided with cross recess far from one end of upper earth brace in insertion protrusion, and raised bottom is being inserted into cross recess setting Portion, depth is in 2~3cm or so, and there are two effects for cross recess, as soon as it is to play certain fixed function, another effect It is guiding, realizes quickly insertion, for this purpose, the insertion blind hole matched with insertion protrusion is provided at the top of lower earth brace, For the internal diameter of blind hole slightly larger than the outer diameter of insertion protrusion, the purpose being arranged in this way is to be inserted into for convenience, is arranged in insertion blind hole There is the cross leading truck matched with cross recess, cross leading truck is exactly the cross structure that two vertically disposed cylinders are formed, It, which possesses, blocks cross recess, another effect of cross leading truck is exactly that the effect limited can by above-mentioned structure setting Make to realize between earth brace and lower earth brace and quickly and accurately connect.

It is more firm in order to connect upper earth brace with lower earth brace, it is further sleeved with retaining mechanism on upper earth brace, Specifically, in the lock sleeve that retaining mechanism includes the locknut being sleeved on upper earth brace and is sleeved on locknut, locknut its Be integrated with lock sleeve setting in fact, as shown in figure 3, in the present embodiment, state for convenience, its is described separately, Be set on locknut for lock sleeve limit spacing collar, the setting of spacing collar, primarily to avoid lock sleeve departing from Locknut, lower earth brace is inserted on the outer wall of blind hole and is provided with the external screw thread that locknut internal screw thread matches, in order to keep locknut fast The work of speed, is provided with lock ball in the bottom of lock sleeve, lock ball is annularly distributed along the inner wall of lock sleeve, on lower earth brace It is provided with the card slot matched with lock ball, the structure that the structure setting of lock ball and card slot is similar to existing umbrella telescopic rod is set Set, lock sleeve is exactly fixed on lower earth brace by purpose, so when in use, when insertion protrusion be inserted into insertion it is blind Kong Hou quickly gets off lock sleeve, is stuck in lock ball in card slot, then, rotates locknut, upper earth brace and lower earth brace are consolidated It is fixed.

In order to further facilitate the use of locknut, makes locknut in locking, keep one between upper earth brace and lower earth brace Fixed stability is additionally provided with auxiliary lock ball on the side wall of insertion protrusion, and it is convex that auxiliary lock ball is annularly distributed in insertion On the outer wall risen, it is inserted on the inner wall of blind hole and is provided with the through-hole that auxiliary lock ball matches, the structure of this structure and lock ball Unanimously, therefore in the present embodiment, detailed description is not added.

It is useful in upper earth brace and the junction setting of insertion protrusion in order to enable locknut and the complete use of upper earth brace In the limiting locking ring of limit locknut, the effect of limiting locking ring can make locknut in upper ground connection as the effect of spacing collar Bar is moved up and down, is rotated, but can not be detached from earth brace, and the purpose being arranged in this way can further promote installation speed.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this The protection scope of type technical solution.
