The specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, accompanying drawing only for exemplary and be not to draw in proportion, represent with identical Reference numeral among the figure by same or analogous element.Preferred embodiment shown in the accompanying drawing only is in order to describe the utility model better, not constitute restriction of the present utility model, and scope of the present utility model is limited by the scope of appended claim.
Fig. 1 is well seat elevation and subsidence regulating device of the present utility model and cement well ring and the well seat sectional view after assembling.This well seat elevation and subsidence regulating device comprises three of being used for can sliding up and down to link to each other with the annular base ring 1 that removably links to each other of cement well ring 5 that is generally annular, with base ring 1 or four elevators 2 (present embodiment is three) and the band handle adjusting bolt 3 that is used for regulating and fixing each elevator.Described elevator 2 can removably link to each other with annular wells seat 6, for example, links to each other with bolt 9 by the well seat.
Fig. 2 A be base ring in the utility model well seat elevation and subsidence regulating device along the sectional view in A-A cross section among Fig. 2 B, and Fig. 2 B is the vertical view of the base ring in the utility model well seat elevation and subsidence regulating device.Shown in Fig. 2 A and 2B, base ring 1 is an annular, wherein circumferentially is distributed with connecting hole 104 (among the figure being three), is used for removably linking to each other with cement well ring, for example is connected with nut 7 by bolt 8.Also be provided with three or four (in the present embodiment being three) circumferential elevator sliding eye 102 that distributes on the base ring 1, in sliding eye 102, slide up and down for elevator 2.Described elevator sliding eye 102 is a through hole, and is arranged to the inboard of contiguous base ring.
In the present embodiment, shown in Fig. 1 and Fig. 2 A, Fig. 2 B, the vertical section that each elevator sliding eye 102 directly makes progress along base ring is a right-angled trapezium, have inclined wall 107 and vertical wall 105, this elevator 2 makes the vertical wall 105 (inclined plane 203 of certain elevator is the inclined wall 107 of corresponding sliding eye also) of the corresponding vertical plane 204 corresponding sliding eyes of elevator from the insertion suitable for reading of sliding eye 102.Because the radially vertical section of sliding eye 102 is a right-angled trapezium, the horizontal rectangular breadth of section of sliding eye 102 diminishes from top to bottom gradually like this.
Shown in Fig. 1 and Fig. 2 A, each elevator sliding eye 102 is provided with screwed hole 101 on its vertical wall 105, regulate bolt 3 for the band handle and be screwed in it, the adjusting of regulating bolt by the band handle can make elevator upper and lower moving between the extreme higher position shown in the solid line and the extreme lower position shown in dotted lines in Figure 1 in Fig. 1.
Fig. 3 A is the sectional view of the elevator in the utility model well seat elevation and subsidence regulating device; Fig. 3 B is the vertical view of elevator in the utility model well seat elevation and subsidence regulating device; Fig. 3 C is the left view of elevator in the utility model well seat elevation and subsidence regulating device.Elevator 2 has horizontal arm 201 and vertical arm 202 for L shaped, wherein has screwed hole 205 on the horizontal arm 201, is used for removably linking to each other with the end flange of well seat 6, for example links to each other by bolt 9.Vertically the end of arm 202 is provided with stop mechanism, this stop mechanism is the combination of through hole and resilient key in the present embodiment, through hole 206 is located at the end of this vertical arm 202, the axis horizontal of this through hole is extended, resilient key 4 inserts in this through hole 206, the length of this resilient key 4 is deviate from from sliding eye to prevent elevator 2 greater than the end opening width of sliding eye 102.
Shown in Fig. 3 A-3B, the vertical arm 202 of this elevator 2 is shaped as right-angled trapezium, it is corresponding with the vertical radial section shape of elevator sliding eye 102, just its thickness is smaller than the correspondingly-sized of sliding eye 102, match with the inclined wall 107 of elevator sliding eye 102 in the inclined plane 203 of this vertical arm 202, thus at the process that the moves up and down medium dip face 203 of elevator all the time against this inclined wall 107.Shown in Fig. 1 and Fig. 2 A, along with the adjusting of band handle bolt 3 in screwed hole 101, the vertical arm 202 of elevator 2 rises in sliding eye 102 and descends.Preferably, when band handle adjusting bolt 3 was rotated counterclockwise, this elevator descended; When needing to rise, elevator and well seat are upwards knocked, mention, reach when needing height, will be with handle to regulate bolt and lock clockwise.Like this, elevator can be regulated at the arbitrary height between two positions shown in Fig. 1 dotted line and the solid line.
Preferably, the adjustable-height of well seat 6 is decided by the length of the vertical arm of elevator 2.By increasing the length of vertical arm 202, the adjusting altitude range of well seat 6 is enlarged.
The course of work of well seat elevation and subsidence regulating device of the present utility model is described below.
Well seat elevation and subsidence regulating device will assemble back integral body with base ring 1, elevator 2, band handle adjusting bolt 3 and the elasticity tip 4 and dispatch from the factory before dispatching from the factory.During installation, earlier that base ring 1 is fastening with cement well ring 5 usefulness bolts 8 and nut 7, then well seat 6 usefulness bolts 9 being connected with elevator 2 (can not be fastening, essential loosening), then elevator 2 is transferred in the higher position, will be with handle to regulate bolt 3 to counterclockwise slowly rotating, then elevator 2 descends with 6 of well seats thereupon, when reaching desired height, stopping operating gets final product; If falling head is crossed when low, well seat 6 and elevator 2 upwards can be knocked, mention, will be with handle to regulate bolt 3 clockwise directions and rotate, reaching needs height that bolt is locked to get final product.
Like this, reach the lifting effect with regard to the combining structure that makes full use of " inclined-plane slip+adjusting bolt ".
By said structure, it is simple to make the utility model make, and lift adjustment speed is fast, and resistance to overturning is good.And compared with prior art, the adjustable range of elevator is big, and (this example is 0～100mm), if the length of lengthening regulating block upright arm 202, adjustable range can be greater than 100mm.
This device can use the adjusting base ring of different size according to well seat size, regulates the well seat of all size.
In the utility model, the number of sliding eye is not limited to three or four, and it can be two or more, as long as can support the well seat.
