Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
In embodiment, as shown in Fig. 1 ~ 3: a kind of periscope telescopic rod, including the mating outer tube 1 of pull and inner tube 2,
One end that the outer tube 1 is close to said inner tube 2 has been evenly arranged several holding claw teeth 3, axis of the holding claw tooth 3 along the outer tube 1
To extension, the sleeve 4 of slip is additionally provided on the outer tube 1；The sleeve 4, which has, to be slid onto 3 periphery of holding claw tooth, makes institute
State holding claw tooth 3 and hold the No.1 position of said inner tube 2 tightly, and be staggered with the holding claw tooth 3, to unclamp the holding claw tooth 3 described
No. two positions of inner tube 2.The present embodiment holds inner tube 2 tightly using the holding claw tooth 3 on outer tube 1, and sleeve 4 passes through sliding energy
Easily realize the fastening and release to holding claw tooth 3；Tightness is able to satisfy pipe between the present embodiment structure outer tube 1 and inner tube 2
The requirement of road periscope, holding claw tooth 3 and the fit structure of sleeve 4 are simple, and pull length can be adjusted easily and fast, can
It is also higher by property.
In embodiment, as shown in Fig. 3 ~ 4: the end of the holding claw tooth 3 is equipped with the mousing-hook 5 to periphery wall protrusion.This reality
The mousing-hook 5 for applying example plays position-limiting action to sleeve 4, is avoided that sleeve 4 falls off from 1 lower end of outer tube.
In embodiment, as shown in Fig. 3 ~ 4: the end of the mousing-hook 5 is small, root is big.The sleeve 4 of the present embodiment is assembling
When, it needs to collapse the lower end of holding claw tooth 3 to center, the structure that the end of mousing-hook 5 is small, root is big facilitates the dress of sleeve 4
Match.
In embodiment, as shown in Fig. 1 ~ 4: the periphery wall of the outer tube 1 sets stop collar 6, the stop collar 6 and the holding claw
The distance of the end of tooth 3 is greater than described twice of 4 length of sleeve.There are two effects for the tool of stop collar 6 of the present embodiment, first is that sleeve
4 are limited, and avoid sleeve 4 from sliding upwards too far, second is that the other end outer tube 1 to upper end limits, prevent it to downslide
Move it is too far, it is specific as shown in Figure 7.
In embodiment, as shown in Fig. 1 ~ 4: the outer tube 1 is assembled by two sections, the line of demarcation of the two sections
For the stop collar 6.Due to outer tube 1 be special pipe, processing cost is higher, therefore is divided into two sections, upper section be standard pipe, under
Section is shaped piece made of extrusion molding, is assembled by modes such as welding or screw threads, this structure, can compared with the special pipe of one
It is substantially reduced cost.
In embodiment, as shown in Fig. 4 ~ 5: the outer wall of the holding claw tooth 3 is the conical surface that root is small, end is big, the sleeve 4
Internal perisporium be the matched tapered surface of outer wall with the holding claw tooth 3.The present embodiment structure, fastening energy of the sleeve 4 to holding claw tooth 3
Realization gradually clamps, therefore reliability is higher.
In embodiment, as shown in figs. 3 and 5: the periphery wall of the sleeve 4 is equipped with stress ring 7.The stress ring 7 of the present embodiment
Convenient to operate to sleeve 4, outer wall is all round and smooth structure, and the feel of operation is also pleasant.
In embodiment, as shown in Fig. 3 ~ 4: one end that the outer tube 1 is close to said inner tube 2 is uniformly provided with several open slots 8,
The remaining position between the axially extending of the outer tube 1, the adjacent open slot 8 of twice constitutes the holding claw tooth 3.
After processing is completed, self-assembling formation holding claw tooth 3, structure is simple, and reliable performance for the open slot 8 of the present embodiment.
It is that the telescopic rod 01 for the multistage that the utility model embodiment assembles is applied to periscope as shown in Fig. 6,7,8
02 three kinds of states, respectively longest, it is most short, separate after schematic diagram, periscope 02 protrude into depth can again longest with most
It realizes and adjusts between short, the telescopic rod 01 of more multistage can also be assembled, to realize adjusting in larger scope, thus
Sufficiently meet the job requirements of periscope 02.
Obviously, the above embodiments of the present invention is merely to illustrate that examples for clearly illustrating the present invention, and is not
Limitations of the embodiments of the present invention.For those of ordinary skill in the art, on above explained basis
On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.
And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model
Protection scope.
