Problems solved by technology

[0005] However, current injectors, in particular those shown in documents US-5 472 598 and US-5 482 628, do not allow for quick assembly / disassembly (components are assembled with screws) and require a non-directional free import and does not ensure optimum sealing after each assembly, nor smooth thermal regulation when necessary

Embodiment Construction

[0017] According to the drawings, the present invention relates to a device 1 for the axial fastening and precise positioning of elongate elements 2, in particular a detachable tubular element which can be hermetically inserted into a 1 in the circulation pipeline.

[0018] The main components of device 1 include:

[0019] A rigid body 3 determines the direction X of the axis and constitutes the base on which a stop 4 and a retaining part 6 are formed or fixed, the stop 4 comprising a first supporting element 5 supporting one end 2' of the elongated element 2 , the maintenance part 6 supports at least part of the elongated element 2, and there is a gap in the axial direction between the stopper 4 and the maintenance part 6;

[0020] The other main component of the device is a removable bracket 7 containing a channel 8 through which at least a part of the elongated element 2 can be slid to allow a calibrated reception of the element, which can be achieved by pressing the stop ...

Abstract

A rigid base (3) defines an axis (X). An abutment (4) forms a resting surface (5) for one end of the long component (2) and a retainer (6). These components (4, 6) are axially separated by a detachable support block with a through passage (8) for sliding adjustment and housing of part of the long component (2). It can be positioned and held between the retainer and the abutment, making surface contact against the abutment. An axially-guided moving component (9) has a second component (10) contacting the other end of the long component (2). The moving component (9) is articulated with two links (11, 11'). These rotate on eccentrics (12, 12'), which pivot on the base (3). They are assembled rigidly with a pivoting cover (13). This swings down over the assembly (4, 6, 9) and the components (5, 7, 10), corresponding with the locked state of the long component. The two eccentric assemblies (12, 12') and links (11, 11') transform the pivoting movement of the cover (13) into translation of the moving component (9).

Description

technical field [0001] The present invention relates to systems and devices for temporarily supporting elongate elements, such as column ovens of gel-filled injectors for use with high pressure chromatography, under pressure. The present invention is directed to a device for assembling elongated elements and corresponding ovens. Background technique [0002] There are currently many applications that allow high-frequency assembly / disassembly of an interchangeable component in a system while ensuring accurate positioning of said component during installation and possibly under stress. [0003] However, the existing devices satisfying these functions are relatively complex in structure, bulky, and require cumbersome operations. [0004] A special case of application of the above mentioned category is found within the scope of high pressure chromatography, more precisely with respect to sample injectors which are part of the instrument. [0005] However, current injectors, in...
