UTILITY MODEL CONTENTS

[0004] In order to make up for the above shortage, the utility model provides a new type prevent loosening lower cylinder body, aims at improving the instability and inconvenience of lower cylinder body fixation in prior art.

[0005] In order to realize the above purpose, the utility model adopts the following technical scheme:

[0006] A new type prevent loosening lower cylinder body, including sleeve, the inner wall of the sleeve is detachably connected with inner sleeve, the inner wall of the inner sleeve is detachably connected with lower cylinder body, the inside of the inner sleeve is detachably connected with two flat pins, and the one end of the flat pin is provided with glue plug installation place;

[0007] As a further description of the above technical scheme:

[0008] The outer wall of two flat pins is detachably connected in the inside of the sleeve, and the outer wall of two flat pins is detachably connected in the inside of the lower cylinder body.

[0009] As a further description of the above technical scheme:

[0010] The internal structure of the lower cylinder body is barb structure, and the assembly and fixation of the lower cylinder body, the inner sleeve, the sleeve and the flat pin are achieved.

[0011] The utility model has the following beneficial effects:

[0012] The novel anti-loose lower cylinder body has the advantages of stable fixation, convenient assembly and disassembly, guaranteed production efficiency, saved manpower, improved worker safety, environmental protection, improved product quality and high economic benefits. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 A novel anti-loose lower cylinder body is provided in the utility model.

[0014] Figure 2 A structure diagram of the flat pin of the novel anti-loose lower cylinder body is provided in the utility model.

[0015] LEGEND:

[0016] 1, outer sleeve; 2, inner sleeve; 3, lower cylinder body; 4, flat pin; 5, rubber plug installation position. DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] REFERENCE Figure 1 With Figure 2 The utility model provides an embodiment: a novel anti-loose lower cylinder body 3, including outer sleeve 1, outer sleeve 1 is the outermost protective shell of whole device, provides preliminary structural support and protection, the inner wall detachable connection of outer sleeve 1 has inner sleeve 2, the inner wall detachable connection of inner sleeve 2 has lower cylinder body 3, and lower cylinder body 3 is core working part, directly participates in material handling process. The inside detachable connection of inner sleeve 2 has two flat pins 4, and the flat pin 4 is used to strengthen the connection stability between lower cylinder body 3 and other components, so that outer sleeve 1 and inner sleeve 2 and lower cylinder body 3 are connected. The outer wall detachable connection of two flat pins 4 is in the inside of outer sleeve 1, and the outer wall detachable connection of two flat pins 4 is in the inside of lower cylinder body 3. One end of flat pin 4 is provided with rubber plug installation position 5, and the design of rubber plug installation position 5 is used to install rubber plug to enhance sealing effect and prevent leakage. The inside structure of lower cylinder body 3 is barb structure, so that lower cylinder body 3 and inner sleeve 2, outer sleeve 1 and flat pin 4 are assembled and fixed.

[0019] Working principle: first, the lower cylinder 3 is put into the inner sleeve 2, then the inner sleeve 2 is put into the outer sleeve 1, then the flat pin 4 is aligned and pressed to the corresponding hole position, and then the rubber plug is installed to the rubber plug installation position 5, so as to complete the assembly. When the equipment starts, because the lower cylinder 3 is provided with barb structure, the barb can effectively prevent any force from outside from causing it to move or fall off. When the interior is overhauled, it can be easily and quickly disassembled by removing each part in the reverse order of installation.

[0020] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
