Detailed Description

The present invention will be described in detail with reference to the following specific examples.

As shown in fig. 1-3, a telescopic arm device includes an arm large tube 1, an arm small tube 2 and an inner and outer member 3, the arm large tube 1 is connected with the arm small tube 2 through the inner and outer member 3, one end of the arm large tube 1 is connected with a large head connecting member 4, one end of the large head connecting member 4 extends into the arm large tube 1, a spring 101 and a steel wire rope 102 are arranged in the arm large tube 1, a first end of the spring 101 is connected with the bottom of the large head connecting member 4, one end of the large head connecting member 4 extending into the arm large tube 1 is provided with a through hole, and a first end of the spring 101 is connected with the through hole of the large head connecting member 4. One end of the steel wire rope 102 is connected with the second end of the spring 101, a groove 321 is arranged on the inner part 3 and the outer part 3, the depth of the groove 321 is 7mm-9mm, the steel wire rope 102 bypasses the groove 321, and the other end of the steel wire rope 102 is connected with the arm small tube 2.

Through set up recess 321 on inside and outside spare, and the degree of depth of recess 321 is 7mm-9mm, among the prior art, the degree of depth of the recess of articulated elements is about 3mm usually in the flexible arm, only plays the guide effect to wire rope, can not change wire rope's path, leads to the spring still to be in great stress throughout the year, and the time is of a specified duration, can influence the performance of spring, shortens its life. In this embodiment, the depth of the groove 321 is increased, so that the travel path of the steel wire rope 102 can be shortened, and when the external telescopic awning is retracted, the tension degree of the spring 101 in the arm large pipe 1 is reduced, so that the stress life of the spring 101 is longer, and the service life of the spring and the telescopic awning is prolonged.

The inner and outer pieces 3 comprise a large outer tube piece 31 and a small inner tube piece 32, the large outer tube piece 31 and the small inner tube piece 32 are connected together, and the grooves 321 are arranged on the small inner tube piece 32.

The other end of the arm large tube 1 is connected with a large tube outer part 31, and the head of the arm small tube 2 is connected with a small tube inner part 32.

The tail part of the arm small tube 2 is connected with a front edge tail part 5, and the front edge tail part 5 is connected with the front edge of the external telescopic tent.

The small pipe inner 32 is connected to the large pipe outer 31 by a pin 33.

The upper and lower both ends of round pin axle 33 all are equipped with decorative cover 34, set up decorative cover 34 and can shelter from the upper and lower both ends of round pin axle 33, improve the aesthetic property, and decorative cover 34 can plastic products, also can be metal products.

Be equipped with first dress trim cover 35 on interior outer part 3, be equipped with second dress trim cover 36 on the recess 321, through setting up dress trim cover 35, can shelter from wire rope 102 on interior outer part 3, avoid wire rope 102 to expose too long easy damage, also improve the whole aesthetic property of flexible arm simultaneously. Meanwhile, because the depth of the groove 321 is 7mm-9mm, the steel wire rope 102 can be completely sunk in the groove 321, so that the second decorative cover 36 can be installed on the groove 321, the steel wire rope 102 is further protected, and the steel wire rope 102 is prevented from being exposed when the first decorative cover 35 is damaged.

The diameter of the steel wire rope 102 is 4mm-6mm, in the prior art, two steel wire ropes with the diameter of 3mm can be used for pulling the spring generally, and the cost is high.

The depth of the groove 321 is 8mm-9mm, and the depth of the groove 321 is 8mm-9mm, so that the traveling path of the steel wire rope 102 can be shortened to the greatest extent.

As shown in fig. 4 and 5, in this embodiment, the state of the wire rope 102 is when the external telescopic awning is opened and retracted, and particularly when the external telescopic awning is retracted, because the groove 321 has a larger depth, the wire rope 102 is clamped in the groove 321, which can greatly shorten the travel path of the wire rope 102, so that the tension degree of the spring 101 is greatly reduced.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
