Abstract

The utility model discloses a quick outer locking device for connection of telescopic rods. The quick outer locking device comprises a plastic lock body, a wrench, an adjusting nut, a connection screw and a rotating pin. The wrench is connected with one end of the connection screw through the rotating pin, and the wrench is capable of rotating around the pin. The plastic lock body is provided with a gap, two sides of the gap are respectively provided with a lock hole in same size, and the other end of the screw penetrates through the lock holes respectively to be fixed with the plastic lock body through the adjusting nut. Compared with the existing products, the locking device is firmer in locking, not easy to loosen in the using process and capable of being adjusted quickly through the adjusting nut if the locking portion is loosened.

Description

Flexible rod connects with quick outer locking device

Technical field

The utility model relates to a kind of flexible rod connection set, relates in particular to flexible rod and connects with quick outer locking device.

Background technique

Mostly on the market is rotational lock formula means of fixation, and old-fashioned wrench-type means of fixation; It is fastening not firm that the former occurs this dual mode easily, loosening easily in the using process, is difficult for locking during improper use, and inconvenience is regulated in the loosening back of latter's lock portion.

Summary of the invention

To above-mentioned technological deficiency, the utility model proposes flexible rod and connects with quick outer locking device.

In order to solve the problems of the technologies described above, the technological scheme of the utility model is following:

Flexible rod connects with quick outer locking device; Comprise plastics lock body, spanner, adjusting nut, attachment screw and rotation pin, said spanner is connected through said rotation pin with an end of said attachment screw, and said spanner can rotate around said rotation pin; Said plastics lock body is provided with the gap; The both sides in said gap respectively are provided with a lockhole of identical size, after the other end of said attachment screw passes said lockhole respectively, fix through adjusting nut and said plastics lock body.

As possibility, be close to said plastic latch body portion after said spanner rotates and be provided with metallic shim.

The beneficial effect of the utility model is: it is more firm to compare existing product locking, is not easy in the using process to become flexible, but and after lock portion is loosening, passes through the adjusting nut rapid adjustment.

Fig. 2 is the plan view of the utility model;

Fig. 3 is the stereogram of the utility model;

Fig. 4 is the user mode figure of the utility model.

Embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explanation below.

Like Fig. 1, Fig. 2 and shown in Figure 3; Flexible rod connects with quick outer locking device; Comprise plastics lock body 1, spanner 5, adjusting nut 2, attachment screw 3 and rotate pin 4, said spanner 5 is connected through said rotation pin 4 with an end of said attachment screw 3, and said spanner 5 can rotate around said rotation pin 4; Said plastics lock body 1 is provided with gap 6; The both sides in said gap 6 respectively are provided with a lockhole 7 of identical size, after the other end of said attachment screw 3 passes said lockhole 7 respectively, fix through adjusting nut 2 and said plastics lock body 1; Be close to said plastics lock body 1 part after said spanner 5 rotates and be provided with metallic shim, can prevent that through this metallic shim the plastics lock body is by spanner 5 wearing and tearing.

During use, when being thickness pipe mosaic mode for telescopic rod tube, extra heavy pipe is connected with plastics lock body upper end close-fitting, and tubule is through plastics lock body lower end circular hole, and is as shown in Figure 4 when spanner 5 is opened, and can pull out or advance flexible rod; The spanner 5 that closes closes up the gap 6 on the lock body, i.e. fixing flexible rod.When the not enough perhaps spanner 5 of coupling mechanism force is too tight, can when spanner 5 open modes, rotate adjusting nut 2, regulate the size in lock body gap 6 and control coupling mechanism force.Regulate very convenient, fixed.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the utility model protection domain.

Claims

1. flexible rod connects with quick outer locking device, it is characterized in that, comprises plastics lock body, spanner, adjusting nut, attachment screw and rotation pin; Said spanner is connected through said rotation pin with an end of said attachment screw; Said spanner can rotate around said rotation pin, and said plastics lock body is provided with the gap, and the both sides in said gap respectively are provided with a lockhole of identical size; After the other end of said attachment screw passes said lockhole respectively, fix through adjusting nut and said plastics lock body.

2. flexible rod according to claim 1 connects with quick outer locking device, it is characterized in that, is close to said plastic latch body portion after said spanner rotates and is provided with metallic shim.
