Abstract
An enclosing device for the hole to accept opener on manhole cover is composed of main cover body, locking axle and fastening plate. Said main cover body consists of tubular axle inserted in the hole and top disk connected to top of tubular axle and embedded in top recess. Said locking axle is inserted int he tubular axle and pushed upward by spring, and has a slave part at top for matching with the drive part of operating handle. Said fastening plate is fixed to lower end of locking axle and its upper arm can be fastened to or separated from the wall of underground way.
Description
The present invention relates to device and be located at locking device on the manhole cover opener receiver hole.
In manhole cover in the past, the receiver hole that the insertion opener of portion located in the above is used be the state with opening be positioned on the road surface and no matter, therefore, through being stopped up by silt particle dust etc. after long-time.Therefore, when opening manhole, desire need carry out preceding operations such as removing silt particle, quite time-consuming for this reason taking a lot of work.
Certainly, also have the proposal in the setting-in receptor holes such as rubber cap, but only embed cap, will be owing to the contact of the tire of driving vehicle and pedestrian's shoes etc. and vibration and break away from receiver hole easily, can't the original inaccessible function of long term maintenance.
Therefore, the object of the present invention is to provide a kind of locking device that can protect receiver hole not to be subjected to the manhole cover opener receiver hole that silt particle dust etc. stops up for a long time.
The present invention is as follows referring now to the explanation of the component part numbers in the accompanying drawing.The present invention's locking device ends plate 15 by cap body 5, locking shaft 9 and button and constitutes.Cap body 5 is inserted beam barrel portion 6 with receiver hole 3, is connected these beam barrel portion 6 upper ends and is flush-mounted in the interior last face portion 8 of the top recess 7 of the horizontal walls 4 around this receiver hole 3 by the opener 2 that is intercalated in manhole cover 1 and constituted.
As shown in Figures 1 and 2, not during the opener 2 of end user's port lid 1, there is the beam barrel portion 6 of cap body 5 to be flush-mounted in the receiver hole 3 of opener, on face portion 8 is flush-mounted in around this receiver hole 3 on this cap body 5 in the face recess 7, can entirely shuts receiver hole 3 thus and can stop the intrusion of silt particle and dust really.
Under this blocked state, what button ended plate 15 is fastened on face ditch portion 14 under the horizontal wall 4 to upper arm parts 16, firmly keep this fastening by the elastic force pressure of spring 10, therefore, cap body 5 can not break away from unintentionally because of contacting or vibrate from receptor hole 3 with tire of driving vehicle etc.
When desire was extracted cap body 5 from receptor hole 3, as shown in Figure 2, the drive division 12 of operating handle 11 was fastened on the follower 13 of locking shaft 9, as shown in Figures 3 and 4, and push handle 11.So button ends the slot part 14 below upper arm parts 16 disengaging horizontal walls 4 of plate 15, locking shaft 9 becomes revolution freely.
As Fig. 5 and shown in Figure 6, operating handle 11 depressed and state revolution to depress, make locking shaft 9 when unblanking the direction revolution, end plate 15 with the rotating button of locking shaft 9 one and come the position that is arranged in receiver hole 3 belows.This in stage remove operating handle 11 press action the time, locking shaft 9 moves up because of the elastic pushing pressure of spring 10, button ends on the plate 15 in arm 16 enters receptor hole 3.
Catch the locking shaft of giving prominence to from the upper end open of the beam barrel portion 6 of cap body 59 the upper end and when receiver hole 3 is extracted cap body 5, but all-round opening receiver hole 3, as Fig. 7 and shown in Figure 9.Therefore, the T font of opener 2 elder generation end 17 is inserted in receiver hole 3, turn round certain angle and is fastened under the horizontal walls 4 after the face ditch portion 14, pulling opener 2 and opening manhole cover 1.
Below, accompanying drawing is carried out simple explanation.
Fig. 1 is the longitudinal diagram of manhole cover opener receiver hole blocked state that is applicable to the locking device of one embodiment of the invention.
Fig. 2 is the planar view of the opener receiver hole blocked state of this manhole cover.
Fig. 3 is the longitudinal diagram of state of pressing the operating handle of this locking device.
Fig. 4 is the planar view of state of pressing the operating handle of this locking device.
Fig. 5 is for returning the operating handle of this locking device the longitudinal diagram of the state that turn 90 degrees.
Fig. 6 is for returning the operating handle of this locking device the planar view of the state that turn 90 degrees.
Fig. 7 is for extracting the longitudinal diagram of the state of this locking device from the opener receiver hole of manhole cover.
Fig. 8 is for extracting the planar view of the state of this locking device from the opener receiver hole of manhole cover.Numbering in the accompanying drawing is described as follows: the elasticity accumulation of energy bullet of last face portion 9-locking shaft, the 10-locking shaft of the top recess 8-cap body of the beam barrel portion 7-horizontal walls of horizontal walls 5-cap body 6-cap body of receiver hole 4-clean-out cover that 1-manhole cover, 2-opener 3-the insertion opener is used

Below, embodiments of the invention are described.
In illustrated embodiment, the top recess 7 of the horizontal walls 4 of manhole cover 1 forms circle, and receiver hole 3 forms elongated groove shape on the diameter of recess 7 in the above, and two inwalls of central portion are provided with the circular arc expansion section.The beam barrel portion 6 of cap body 5 is, is connected with the central portion of face portion 8 on circle, states the circular arc expansion section before being intercalated in receiver hole 3.Button ends plate 15 and is made of the band-like plate that is bent to the U font.
The follower 13 of locking shaft 9 is made of 13a of rounded protuberance portion and eccentric recess 13b, the drive division 12 of operating handle 11 is by have can not be with the simple and easy lock function of common instrument rotating operations such as screwdriver to should being made of circular depressions 12a and eccentric projection 12b by follower 13, possessing.
In addition, locking shaft 9 bottoms that are inlaid in the beam barrel portion 6 of cap body 5 with freely the state of moving up and down are fixed with button and end plate 15, under above-mentioned blocked state, this button ends on the plate 15 to arm 16 to being fastened on face ditch portion 14 under the horizontal walls 4 really, therefore, can not have cap body 5 for because of with the contacting and situation that vibration breaks away from receptor hole 3 of driving vehicle tire etc., can keep blocked state steadily in the long term.
