Abstract
The utility model discloses a flexible cover, including the flexible cover body, the flexible cover body includes first cavity connecting pipe, second cavity connecting pipe, third cavity connecting pipe, second cavity connecting pipe links to each other with first cavity connecting pipe, third cavity connecting pipe respectively, the external diameter of first cavity connecting pipe equals the external diameter of third cavity connecting pipe, the internal diameter of first cavity connecting pipe is greater than the internal diameter of third cavity connecting pipe, the external diameter of first cavity connecting pipe is greater than the external diameter of second cavity connecting pipe, the internal diameter of first cavity connecting pipe is greater than the internal diameter of second cavity connecting pipe. A flexible cover, its simple to operate avoids the two shafts contact friction through the setting of external diameter in the connecting pipe to the damage produces, while can be adjusted according to the size of axle is nimble, improves flexible cover's performance.
Description
Technical field
The utility model relates to a kind of telescopic cover.
Background technique
Telescopic cover is well used in the axle of lathe is connected with axle.The telescopic cover used at present its mainly play connection function, but be arranged on two its Long Term Contacts of axle frictions in telescopic cover, easily produce damage, thus affect the normal use of lathe.
Model utility content
The purpose of this utility model is to provide a kind of telescopic cover, and it is easy for installation, avoids two axle contact frictions by the setting of connecting tube internal-and external diameter, thus produces damage; Can regulate according to the flexible in size of axle simultaneously, improve the usability of telescopic cover.
In order to achieve the above object, the technical solution of the utility model is:
A kind of telescopic cover, comprise telescopic cover body, described telescopic cover body comprises the first hollow connection tube, second hollow connection tube, 3rd hollow connection tube, described second hollow connection tube respectively with the first hollow connection tube, 3rd hollow connection tube is connected, the external diameter of described first hollow connection tube equals the external diameter of the 3rd hollow connection tube, the internal diameter of described first hollow connection tube is greater than the internal diameter of the 3rd hollow connection tube, the external diameter of described first hollow connection tube is greater than the external diameter of the second hollow connection tube, the internal diameter of described first hollow connection tube is greater than the internal diameter of the second hollow connection tube.
The outer side wall of described second hollow connection tube and the outer side wall antarafacial of the first hollow connection tube are installed, and the madial wall of described second hollow connection tube and the madial wall antarafacial of the first hollow connection tube are installed.
Be separately installed with the first positioning block, the second positioning block in described first hollow connection tube, and all conflict with the first positioning block, the second positioning block and be connected in the top of described second hollow connection tube.
The beneficial effects of the utility model are: a kind of telescopic cover, and it is easy for installation, avoid two axle contact frictions by the setting of connecting tube internal-and external diameter, thus produce damage; Can regulate according to the flexible in size of axle simultaneously, improve the usability of telescopic cover.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of telescopic cover as shown in Figure 1, comprise telescopic cover body 1, described telescopic cover body 1 comprises the first hollow connection tube 2, second hollow connection tube 3, 3rd hollow connection tube 4, described second hollow connection tube 3 respectively with the first hollow connection tube 2, 3rd hollow connection tube 4 is connected, the external diameter of described first hollow connection tube 2 equals the external diameter of the 3rd hollow connection tube 4, the internal diameter of described first hollow connection tube 2 is greater than the internal diameter of the 3rd hollow connection tube 4, the external diameter of described first hollow connection tube 2 is greater than the external diameter of the second hollow connection tube 3, the internal diameter of described first hollow connection tube 2 is greater than the internal diameter of the second hollow connection tube 3.
The outer side wall of described second hollow connection tube 3 and the outer side wall antarafacial of the first hollow connection tube 2 are installed, and the madial wall of described second hollow connection tube 3 and the madial wall antarafacial of the first hollow connection tube 2 are installed.
Be separately installed with the first positioning block 5, second positioning block 6 in described first hollow connection tube 2, and all conflict with the first positioning block 5, second positioning block 6 and be connected in the top of described second hollow connection tube 3.
In use, thicker coupling shaft can be inserted in the first hollow connection tube 2, thinner coupling shaft inserts telescopic cover described in the present embodiment in the 3rd hollow connection tube 4; The setting of the first positioning block 5 and the second positioning block 6 can not only avoid two coupling shaft frictions impaired, and can play the effect of buffering, thus avoids coupling shaft can not normally use because impact force is impaired.Because the madial wall of the second hollow connection tube 3 and the madial wall antarafacial of the first hollow connection tube 2 are installed, can be positioned the second hollow connection tube 3 for thinner coupling shaft, can be positioned in the 3rd hollow connection tube 4 for thicker coupling shaft, described telescopic cover can connect the coupling shaft of different size.
A kind of telescopic cover of the present embodiment, it is easy for installation, avoids two axle contact frictions by the setting of connecting tube internal-and external diameter, thus produces damage; Can regulate according to the flexible in size of axle simultaneously, improve the usability of telescopic cover.
