Description
Technical Field
The invention discloses a circular tube sleeving device.
Background
In many cases, it is desirable to use a longer tube, such as: when the axial nailing device is in actual use, the nailing treatment is required to be carried out on the ceiling, the nailing device is required to be installed on the upper portion of the circular tube (supporting rod), personnel can hold the tail end of the circular tube on the ground to carry out axial force application operation, and the circular tube with various lengths cannot be provided in practice due to different layer heights of various houses, so that the adjustable design is required for the length of the circular tube.
The conventional length adjustment mode is to divide the circular tube into sections, the joint is respectively provided with an internal thread and an external thread, and the length is increased after a plurality of circular tubes are screwed, but the device has the defects that: the storage, arrangement and transportation of a plurality of pipes are all very inconvenient, and time and energy are wasted in the assembly and disassembly, in addition, when the number of the sections of the pipes is too much, the nail shooter at the upper end has the swing phenomenon (because the clearance exists all the time between the threaded fit, the locking function is not enough).
In order to overcome the defects, a circular tube sleeving device appears in the market, namely circular tubes with different tube diameters are used, the circular tube of the upper stage can be stored in the circular tube of the lower stage, the length is relatively short when the circular tube sleeving device is not used, the circular tube can be stretched out step by step when the circular tube sleeving device is used, and the length is fixed by matching a bolt with a pin hole. This type of device has better solved the accomodate problem, but the fixed mode of bolt needs additional annex and technology hole, and the location is also comparatively inconvenient when using, and the biggest defect lies in: when the nail shooting device shoots nails, a large impact force (20-30 newtons) is generated, and the force can greatly damage the pin hole matching structure, and in fact, after the nail shooting device is used for several times, the pin holes are severely deformed.

the thread A is matched with the thread B;
a bushing is arranged between the opening spring A and the opening spring B; the two end surfaces of the bushing can respectively act on the opening spring A and the opening spring B;
the upper tube can slide in the nut, the lower tube assembly, the opening spring A, the opening spring B and the bushing before the threads A and the threads B are not completely matched.
Further optimizing: the outer wall of the upper pipe is provided with an annular blind groove.
Further optimizing: the lower pipe assembly is provided with an observation hole, and the opening spring A can be observed.
Further optimizing: the upper pipe is provided with a positioning mark.
Further optimizing: spring anti-drop grooves are arranged in the inclined table A and the inclined table B.
Further optimizing: the lower pipe assembly and the nut are provided with force applying devices.
The invention has the beneficial effects that: the problem that the casing structure can effectually solve the multitube and accomodate, the cooperation of innovative use sloping platform and opening spring utilizes bush oppression opening spring, makes it shrink along the inclination to hold tightly the upper tube, reach the purpose of the fixed locking of axial of high strength, can bear very big impact force, two upper and lower springs lock simultaneously moreover, have guaranteed holistic rigidity, have avoided the rocking phenomenon after the installation between two section circular tubes.
The invention is further described below by way of examples with reference to the accompanying drawings.

Fig. 2 is a cross-sectional view of fig. 1.
FIG. 3 is a schematic diagram of an unlocked state.
Fig. 4 is a cross-sectional view of fig. 3.
Fig. 5 is a schematic view of the locked state.
Detailed Description
In the figure: 1 is an upper pipe, the lower pipe assembly comprises a lower pipe body 17 and outer sleeves 2,3 are inclined tables B,4 is an opening spring A,5 is a thread A,6 is a nut, 7 is a thread B,8 is an inclined table A,9 is an opening spring B,10 is a bushing, 11 is an annular blind groove, 12 is an observation hole, and 16 is a spring anti-falling groove.
Example 1:
in the unused state, the pipe diameter of the upper pipe 1 is smaller than that of the lower pipe assembly, so that the upper pipe 1 can be accommodated in the lower pipe assembly.
When the upper tube 1 is used, the upper tube 1 is pulled out to a required position, and the pipe diameter of the upper tube 1 is smaller than the inner diameters of the nut 6, the bushing 10, the opening spring A4 and the opening spring B9, so that the nut 6 and the bushing 10 do not hinder the action of the upper tube 1.
After the upper tube 1 is pulled out to a desired position (where the lower end of the upper tube 1 is still within the lower tube assembly), the nut 6 is tightened, and the nut 6 moves down the lower tube assembly due to the engagement of threads A5 and B7.
The following is the core of the technology: during the downward movement of the nut 6, the force transmission relationship is: nut 6-ramp B3-opening spring B9-bushing 10-opening spring A4-ramp A8-down tube assembly. The nut 6, the inclined table B3, the bushing 10, the inclined table A8 and the lower pipe assembly are all rigid bodies, and only the opening spring B9 and the opening spring A4 have deformation effect.
That is to say: the bushing 10 applies force to the opening springs B9 and A4 which are contacted with the two ends of the bushing, and the opening springs B9 and A4 are respectively arranged on the inclined table B3 and the inclined table A8, so that the two opening springs shrink and deform along the inclination, thereby tightly holding the upper pipe 1 therein and achieving the effect of fixedly locking the upper pipe 1.
When the upper tube 1 needs to be released, the nut 6 is unscrewed, and the two opening springs are reset, so that the upper tube 1 is also released.
Example 2:
in embodiment 1, two opening springs are tightly held on the wall of the upper pipe 1, in order to obtain larger axial bearing force, an annular blind groove 11 is arranged on the upper pipe 1 on the basis of embodiment 1, and the opening springs A4 are tightly held on the annular blind groove 11, so that larger axial impact force can be borne.
Example 3:
on the basis of embodiment 2, in order to accurately realize the matching of the opening spring A4 and the annular blind groove 11, an observation hole 12 is formed in the lower pipe assembly so as to observe and position, and then the nut 6 is screwed down, so that the opening spring A4 can accurately clamp the annular blind groove 11.
Example 4:
on the basis of the embodiment 2, in order to accurately realize the matching of the opening spring A4 and the annular blind groove 11, the following different ways from the embodiment 3 are adopted: the upper pipe 1 is provided with a positioning mark, the positioning mark is always positioned at an observable position, the spacing between the parts is controlled equally, and when the positioning mark is level with the upper end face of the nut 6, the opening spring A4 can be accurately matched with the annular blind groove 11.
Example 5:
in the assembly process, the opening springs B9 and A4 are fed onto the inclined platform B3 and A8 from the end parts, so that the two opening springs can fall off when the two opening springs are inverted, a spring falling-off prevention groove 16 is formed in the inclined platform A8 and B3, and the opening springs B9 and A4 can fall into the spring falling-off prevention groove 16 after slightly deforming when assembled. After falling, even if inverted, the two opening springs are not separated.
Example 6:
after all, the nut 6 needs a large force for screwing and unscrewing, and for convenience of operation, a force application device can be arranged outside the nut 6 and the lower pipe assembly, and the force application device can be in the following form: knurling, slot milling, processing into flat square forms, etc., so as to use external equipment such as wrenches, etc.
