Abstract
The invention discloses a protective door structure for a five-jack socket. The protective door structure is characterized in that: a pressure plate is arranged in a base; the surface of the pressure plate is provided with a protective door; one end of the protective door is pressed against one end of a spring; and the other end of the spring is pressed against the inner wall of a front cover. The one-piece independent protective door structure realizes a multi-jack socket protection function, has a simple and rational integral product structure, high working stability performance and high practicability, can effectively prevent the phenomenon of single-jack locking, can be popularized to the five-jack socket and a three-jack socket, and compared with the prior art, has prominent substantive characteristics and achieves remarkable improvements.
Description
Technical field:
The present invention relates to the technical field of carriageway inspection shaft cover plate, a kind of specifically shutter structure that is used for five spring hole scokets, particularly its mechanical connecting structure.
Background technology:
Documents; the patent No.: ZL200720122183.X; notification number: CN201075448; patentee: Shenzhen City Baoan District Songgang Yisheng Products Factory; this case discloses " a kind of socket protective door "; comprise socket panel in this product structure; its inboard is provided with spring and two shutters; each shutter comprises rotating shaft and the plugging block that connects as one; described two plugging block correspondences are plugged in two jacks of socket panel, can be opened one inboard that is placed on this socket panel by the plug end subitem; this support or socket panel one of them is provided with circular groove at least; the two ends of described shutter rotating shaft are rotatable to be placed in this groove, and this mid-stent is established a spring stack, and described spring is a helical spring; it is arranged on the spring stack, and its bipod is connected with the shutter of both sides.
From above-mentioned existing socket protective structure, can not find out; this class formation only is applicable to simple two spring hole scokets; and two independent protection doors have been adopted; this class formation failure rate in actual use is high; stuck the manifesting of simple gate often appears; Total tune and functional extreme difference, and can't be applied in five spring hole scokets and three pole sockets.
So still need existing socket protective door is further improved, require it to be applied in the porous socket, and have good job stability and Total tune.
Summary of the invention:
The object of the present invention is to provide a kind of shutter structure that is used for five spring hole scokets; it adopts single shutter structure; utilize it to cooperate with the single of pressing plate; realize the united and coordinating of each jack; stuck the manifesting of single jack can not appear; and can be applied to overcome the shortcoming and defect that exists in the prior art in five spring hole scokets.
To achieve these goals; technical scheme of the present invention is: a kind of shutter structure that is used for five spring hole scokets; it mainly comprises base; the cover that matches with base; be provided with utmost point connector assembly in the base, it is characterized in that: be provided with pressing plate in the described base, clamp surface is provided with shutter; shutter one end props up spring one end, and the spring other end props up the cover inwall.
The invention discloses a kind of shutter structure that is used for five spring hole scokets; it adopts single piece type independent protective door; realize the slotting defencive function of porous; product overall structure advantages of simple; and single piece type shutter structure can effectively prevent stuck the manifesting of single jack, has good working stability performance, and this kind structure can be promoted and arrive in five spring hole scokets and the Three-hole socket; have good practicability, have outstanding substantive distinguishing features and marked improvement compared to existing technologies.
Description of drawings:
Fig. 1. be general assembly drawing of the present invention
Fig. 2. be structural representation of the present invention
Embodiment:
With reference to the accompanying drawings, the present invention further is described
The present invention is a kind of shutter structure that is used for five spring hole scokets; it mainly comprises end base 1; the cover 2 that matches with base 1 is provided with utmost point connector assembly 15 in the base 1, it is different from prior art and is: be provided with pressing plate 3 in the described base 1; pressing plate 3 surfaces are provided with shutter 4; shutter 4 one ends prop up spring 5 one ends, and spring 5 other ends prop up cover 2 inwalls, and spring can assist shutter to reset; when plug pulls away socket, shutter is upwards resetted.
In the specific implementation; one end of described shutter 4 is provided with breach 6; the bottom of breach 6 is provided with the spring joint pin 7 of projection; one end of shutter 4 is provided with three inclined-planes 8 side by side; the inclined-plane can form plugging effect at the jack place; separate interval between the inclined-plane 8, shutter 4 places of spring joint pin 7 both sides are provided with shutter oblique cutting hole 9, and shutter 4 lower surfaces are provided with chute.
In the specific implementation; described pressing plate 3 centers are provided with the shutter gib block 10 that matches with chute; (shutter 4 can be along gib block 10 upper and lower displacements; and utilize spring to reset); the both sides of gib block 10 are provided with pressing plate oblique cutting hole 11; shutter gib block 10 tops are provided with pressing plate earth jack 12, and pressing plate 3 places of pressing plate earth jack 12 both sides offer pressing plate twin jack 13.
In the specific implementation, four jiaos of described pressing plate 3 all form inside circular arc chamfering 14, cooperate the inner erection column structure of base, have good locating effect.
This product is a kind of shutter structure of using more; the seesaw structure of the dual-purpose slotting employing in the two poles of the earth; what the two poles of the earth band grounding receptacle was adopted is only just can open L after earth electrode is opened earlier; the combined protective door of the N utmost point; the dual-purpose slotting shutter motion principle in the two poles of the earth: when the shutter one pole inserts; shutter swings up and down and is stuck in cover and the pressing plate draw-in groove; can not be toward lower slider; play the protection effect of jack; when two polar circles are inserted or during the flat insertion in the two poles of the earth; shutter place both sides force balance; can not swing up and down, under the effect of plug power, move down and open jack; plug can very smooth and easy insertion jack in (when one pole inserts; effective displacement of shutter has only 0.6mm, can be fixed in 0.6mm from marketing, diameter 1mm probe can not insert).
