Abstract

The utility model provides a suppress piecing devices, includes application of force subassembly, fixing sleeve, smooth movable sleeve and screwed joint. Application of force subassembly includes eccentric depression bar and eccentric briquetting, and on eccentric depression bar was fixed in eccentric briquetting, eccentric briquetting was connected with fixing sleeve through the round pin axle, smooth movable sleeve overlaps in fixing sleeve, is equipped with convex structure in the smooth movable sleeve, and raised head face is with to suppress target up end machinery hard sealed, screwed joint and fixing sleeve are connected. The utility model discloses a glue ring soft seal, terminal surface machinery seal structure firmly, improve the leakproofness of device, adopt smooth movable sleeve, eccentric depression bar, briquetting structure, easy operation, labour saving and time saving improves work efficiency, the device adopts prevents suppressing target drunkenness structure, the security that greatly improves the device.

Description

One suppresses piecing devices
Technical field
This utility model relates to gas pressure test field, is specifically related to one and suppresses piecing devices.
Background technology
During flat plate collector gas pressure test, the very easy pressure device of commonly used one: one block of rubber is placed between heat collector copper pipe End and machinery capping apparatus, copper pipe end face is made to fit tightly with rubber by extruding, when carrying out gas pressure test due to pressure fluctuations, this device can increase suddenly because of pressure causes copper pipe to be subjected to displacement with rubber surface and misplace, so that copper pipe jumps out, the person is damaged.Simultaneously because copper pipe tube wall is relatively thin, easily rubber is cut badly and because of unbalance stress, make copper pipe deformation not re-use.Needing 3-4 people when suppressing, suppressing a set of copper core net needs about 5 minutes.It can thus be appreciated that traditional pressure device existence takes time and effort, extremely inefficient, material consumption security problems excessive, inadequate.
Utility model content
This utility model by provide a kind of suppress that piecing devices solve that existing pressure device exists take time and effort, extremely inefficient, material consumes security problems excessive, inadequate.
This utility model is solved the technical problem that to adopt the following technical scheme that and realize:
Piecing devices suppressed by a kind of copper pipe, including force assembly, fixing sleeve, sliding sleeve and nipple.Described force assembly includes eccentric compressive bar and eccentric briquetting, and eccentric compressive bar is fixed on eccentric briquetting, and eccentric briquetting is by bearing pin and fixing sleeve connection;Described sliding sleeve is placed in fixing sleeve, and described sliding sleeve is with air pipe interface, and air pipe interface snaps in fixing sleeve sliding tray;Being provided with boss structure in sliding sleeve, raised head face seals firmly with suppressing target upper surface machinery;Described nipple and fixing sleeve connection.
Described eccentric briquetting is by bearing pin and fixing sleeve connection, in case briquetting horizontal looseness.
Described fixing sleeve side has sliding tray, makes sliding sleeve freely up and down move.
Described nipple screw thread is provided with back-up ring, and described back-up ring is threaded collar, to adjust the degree of depth of the fixing sleeve of nipple entrance.
The technique effect that this utility model is useful: use glue ring soft seal, mechanical end face hard sealing structure, improves the sealing of device;Employing sliding sleeve, eccentric compressive bar, briquette structure, simple to operate, time saving and energy saving, improve work efficiency;Device uses to be prevented suppressing target play structure, is greatly enhanced the safety of device.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, achieve the goal and effect is readily apparent from, below in conjunction with the accompanying drawings this utility model be described in further detail:
One suppresses piecing devices, including force assembly, fixing sleeve 3, sliding sleeve 4 and nipple 6.Described force assembly includes eccentric compressive bar 1 and eccentric briquetting 2, and eccentric compressive bar 1 is fixed on eccentric briquetting 2, and eccentric briquetting 2 is connected with fixing sleeve 3 by bearing pin;Described sliding sleeve 4 is placed in fixing sleeve 3, and described sliding sleeve 4 is with air pipe interface, and air pipe interface snaps in and is provided with boss structure in fixing sleeve 3 sliding tray in sliding sleeve 4, and raised head face seals firmly with suppressing target 8 upper surface machinery;Described nipple 6 is connected with fixing sleeve 3.
As shown in figures 1 and 3, copper pipe is stretched in fixing barrel casing 3, lower pressure eccentric compressive bar 1, sliding sleeve 4 is pushed away forward by the eccentric briquetting 2 of eccentric compressive bar linkage, make raised head face and suppress the hard sealing of target 8 upper surface machinery, ring 5 end face of sliding sleeve 4 lower end crush seal simultaneously so that it is target 8 radially deformation is protruding along suppressing, it is squeezed in and suppresses on target 8 outer wall, form soft sealing structure.Back-up ring 9 can adjust the degree of depth within the fixing sleeve 3 of nipple 6 entrance at any time according to suppressing target 8 length, to ensure that suppressing target 8 upper surface fitted with sliding sleeve 4 moment, thus different length is suppressed target 8 and carries out stress test.Additionally, interior hoop 7 carry anti-skidding locking groove and termination with locking jaw structure, to prevent from suppressing target 8 play during suppressing.
Of the present utility model ultimate principle and principal character and of the present utility model advantage be more than shown and described, but this utility model being not restricted to the described embodiments.On the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.
