Rod body assembly and there is its retractable spontoon
Technical field
This utility model relates to defending fixture fields, in particular to a kind of rod body assembly and the flexible police with it
Rod.
Background technology
Retractable spontoon of the prior art is typically assembled by many rod body assembly combinations, can between many rod body assemblies
With the most flexible.Rod body assembly is made up of tube head and body, and the connection transition position of tube head and body is provided with cannelure, cannelure
Inside it is arranged with to change the regulation ring of rod body assembly external diameter such that it is able to regulation rod body assembly and other one section of rod body assembly dress
The gap joined.
Tube head and the body of existing rod body assembly are formed in one, it is impossible to dismantle.Install for convenience, existing
Regulation ring is the annular solid with opening, when installing regulation ring, by being broken into two with one's hands by the opening of regulation ring, and then is fastened on tube head
With in the cannelure of the transition position of body, thus ensure between two sticks body assembly when another root rod body assembly assembles
It is in suitable gap, it is to avoid two sticks body assembly rocks.
But, the regulation ring of open type the most easily comes off, and easily slide into the body of rod body assembly
Other positions cause two sticks body assembly stuck, affect the service life of retractable spontoon.
Additionally, due to the tube head of rod body assembly and body are formed in one, cause the peace of the spacing ring being arranged on body
Dress bothers the most very much.

Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Combination mutually.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Rod body assembly according to this utility model embodiment, as depicted in figs. 1 and 2, including body 10, tube head 20 and regulation
Ring 30, tube head 20 is detachably connected with body 10, and one end of body 10 is provided with the first location division, and one end of tube head 20 is arranged
Having the second location division, form locating slot 40 between the first location division and the second location division, regulation ring 30 is set in locating slot 40.
The rod body assembly of application the technical solution of the utility model, by arranging body 10, tube head 20 and regulation ring 30, pipe
20 detachably connected with body 10, and one end of body 10 is provided with the first location division, and one end of tube head 20 is provided with second
Location division, forms locating slot 40 between the first location division and the second location division, regulation ring 30 is set in locating slot 40, thus
When rod body assembly and another root rod body assembly use after assembling, regulation ring 30 is not easy to come off or slide into other of rod body assembly
Position by stuck for two sticks body assembly, solve the most stuck between the two sticks body assembly of retractable spontoon of the prior art,
The problem affecting service life.
When being embodied as, regulation ring 30 is closed-loop, outside the external diameter of regulation ring 30 maximum more than body 10 and tube head 20
Footpath such that it is able to increase the assembling diameter of body 10.Body 10 is hollow pipe, and the end of body 10 has first step structure
11, the first location division is the step surface of first step structure 11;The end of tube head 20 has that the tube chamber with body 10 mates
Two ledge structures 21, the second location division is the step surface of second step structure 21, the insertion body 10 of second step structure 21
In tube chamber, the fin of the fin of first step structure 11 and step surface and second step structure 21 forms locating slot 40, regulation
Ring 30 is set in locating slot 40, and be limited in the fin of first step structure 11 and second step structure 21 fin it
Between.
Alternatively, tube head 20 uses the mode of interference fit or uses the mode of threaded engagement to be connected with body 10,
Before connection, first regulation ring 30 is set in the step surface of first step structure 11, then tube head 20 is assembled with body 10.
Owing to tube head 20 and body 10 are detachable assembling, therefore, the assembling of enclosed regulation ring 30 is not interfered with, and in assembling
After Hao, regulation ring 30 is stuck in locating slot 40, and its shape will not change, and therefore, regulation ring 30 will not go out after assembling
Now slide, thus avoid rod body assembly and another root rod body assembly after assembling, to regulate ring 30 and be stuck in other positions general of body 10
Two sticks body assembly is stuck.
In order to make rod body assembly and another root rod body assembly avoid rod body assembly by another root rod body assembly after assembling
It is drawn out of or is thrown out of, as shown in Figures 2 and 3, the body 10 of rod body assembly is also arranged with spacing ring 50, alternatively, body
Being provided with mounting groove 60 on 10, mounting groove 60 is near one end of tube head 20, and spacing ring 50 is set in mounting groove 60.Rod body assembly
It is plugged in another root rod body assembly by one end of its tube head 20, after assembling, when rod body assembly is by another root rod body assembly
When reaching maximum position, limited ring 50 blocks, it is possible to prevent rod body assembly to be drawn out of by another root rod body assembly or get rid of
Go out.
Alternatively, spacing ring 50 has two, is provided with barrier ring 70 between two spacing rings 50, and barrier ring 70 is the most sheathed
In mounting groove 60, thus two spacing rings 50 are spaced from each other.Arrange two spacing rings 50 to damage at a spacing ring 50
In bad time, continue to play position-limiting action, prevent rod body assembly to be drawn out of or be thrown out of.Spacing ring 50 uses the higher steel system of hardness
Become, spacing ring 50 has an opening, when installing spacing ring 50, first spacing ring 50 is enclosed within the first step of body 10
In structure 11, using the instrument with certain taper to be strutted by the opening of spacing ring 50 subsequently, the internal diameter making spacing ring 50 is bigger
In the fin of first step structure 11, so that the fin that spacing ring 50 can cross first step structure 11 enters into mounting groove
In 60, after spacing ring 50 reinstatement, the external diameter of its internal diameter and mounting groove 60 matches, and can be enclosed within mounting groove 60.Barrier ring
70 is identical with the installation method of spacing ring 50, does not repeats at this.
According to another embodiment of the present utility model, it is provided that a kind of retractable spontoon, including rod body assembly, this rod body assembly
Rod body assembly for above-described embodiment.The retractable spontoon of the rod body assembly of application above-described embodiment, it is possible at rod body assembly with another
When using after a piece rod body assembly assembling, regulation ring 30 is not easy to come off or slide into other positions of rod body assembly by two sticks
Body assembly is stuck, solve the most stuck between the two sticks body assembly of retractable spontoon of the prior art, affect service life
Problem.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
