[0010] A connection assembly, the connection assembly is used in conjunction with the anti-slip ring as described above, wherein:

[0011] The connecting assembly comprises a connecting pipe and a gland;

[0012] The connecting pipe is provided with an anti-slip shoulder, the aperture of which is larger than the inner diameter of the anti-slip ring, smaller than the outer diameter of the anti-slip ring, and larger than or equal to the outer diameter of the connected part;

[0013] The pressure cover is detachably connected to the end of the connecting pipe, and the pressure cover can extend into the connecting pipe to squeeze and fix the outer end of the anti-slip ring on the anti-slip shoulder.

[0020] Preferably, the anti-slip assembly further comprises a sealing ring, and a sealing groove for accommodating the sealing ring is provided in the connecting pipe of the connecting assembly;

[0021] After assembly, the sealing ring, the anti-slip ring and the end cover are arranged in sequence from the inside to the outside along the axial direction of the connecting pipe.

[0022] Preferably, in the above-mentioned anti-slip assembly, the sealing groove is a tapered groove, wherein:

[0023] The end of the tapered groove away from the end cover has a larger aperture and is provided with a limiting boss;

[0024] The aperture of one end of the tapered groove close to the end cover is smaller and is adjacent to the anti-slip shoulder;

[0025] The axial length of the tapered groove is greater than the axial length of the sealing ring.

Then, after the gland and the connecting pipe are fixed in place, the anti-slip ring can be squeezed to prevent the connected part from slipping. The anti-slip process is specifically as follows:

[0030] As the gland gradually penetrates into the connecting pipe and squeezes the anti-slip ring, the anti-slip ring gradually deforms radially. The anti-slip ring is initially a conical cylindrical ring structure, and then gradually transforms into a flat ring structure. In this way, the aperture of the inner end of the anti-slip ring (that is, the end where the anti-slip teeth are located) will gradually become smaller. At this time, if the connected part is a flexible pipe fitting, the anti-slip teeth will penetrate the outer wall of the flexible pipe fitting; if the connected part is a rigid pipe fitting, the anti-slip teeth will squeeze and produce a great friction force, thereby achieving the effect of clamping and anti-slip.

[0031] It can be seen from the above technical solutions that the anti-slip ring, the connecting assembly and the anti-slip assembly provided by the present invention can achieve a good anti-slip effect through the radial deformation of the anti-slip ring.

[0032] Furthermore, in the anti-slip assembly provided by the present invention, a good sealing effect can be achieved through the sealing ring and the sealing groove.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] First specific embodiment

[0049] See also Figure 1 and Figure 2 , Figure 1 It is a triaxial side view of the anti-slip ring provided in the first specific embodiment of the present invention; Figure 2 It is a schematic diagram of the cross-sectional structure of the anti-slip ring provided in the first specific embodiment of the present invention when it is in two different states.

[0050] The first specific embodiment of the present invention provides an anti-slip ring, which is a conical cylindrical structure, with the end with a larger diameter being the outer end and the end with a smaller diameter being the inner end, and the inner end is provided with an anti-slip tooth 31.

[0051] The inner diameter of the anti-slip ring is set according to the outer diameter of the connected part. Under normal conditions, the inner diameter of the anti-slip ring is greater than or equal to the outer diameter of the connected part; when the anti-slip ring is axially squeezed, the inner diameter of the anti-slip ring is smaller than the outer diameter of the connected part.

[0052] Moreover, when selecting the material of the anti-slip ring, the material is required to have a certain rigidity and deformation capacity. For example, stainless steel, aluminum, copper or hard plastic can be used to manufacture the anti-slip ring.

[0053] Preferably, the inner end of the anti-slip ring is provided with a plurality of anti-slip teeth 31, and the plurality of anti-slip teeth 31 are sequentially arranged along the circumference of the inner end of the anti-slip ring;

[0054] Preferably, the outer end of the anti-slip ring is further provided with a push fold 32, and the push fold 32 is an annular fold, and the plane where the annular fold is located is perpendicular to the central axis of the anti-slip ring.

[0055] Second specific embodiment

[0056] The second specific embodiment of the present invention provides a connection assembly, which is used in conjunction with the anti-slip ring provided in the first specific embodiment of the present invention.

[0057] Specifically, see Figures 3 to 5 The connection assembly provided in the second specific embodiment of the present invention includes a connection pipe 1 and a gland 4. Wherein:

[0058] The connecting tube 1 is provided with a cavity 11 for accommodating the connection piece to pass through, and is provided with a stop shoulder 13; the aperture of the stop shoulder 13 is larger than the inner end diameter of the stop ring 3 and smaller than the outer end diameter of the stop ring, so as to cooperate with the gland 4 to axially squeeze the stop ring 3; and the aperture of the stop shoulder 13 is larger than or equal to the outer diameter of the connection piece to accommodate the connection piece to pass through;

[0059] The gland 4 is a hollow structure through which the connected part can pass, and the gland 4 is detachably connected to the end of the connecting pipe 1; moreover, the gland 4 can extend into the connecting pipe 1 to squeeze and fix the outer end of the anti-slip ring 3 on the anti-slip shoulder 13.

[0060] When the outer end of the locking ring 3 is not squeezed by the gland 4, its state can be seen in Figure 2A1 in the figure; as the outer end of the anti-slip ring 3 is squeezed by the gland 4 and approaches the anti-slip shoulder 13, the anti-slip shoulder 13 squeezes the middle section of the anti-slip ring 3 outwards. At this time, the anti-slip ring 3 is radially deformed due to the axial extrusion force, and the inner end aperture becomes smaller and the outer end aperture becomes larger, so that the anti-slip teeth 31 squeeze the connected part in the connecting pipe 1 to achieve the anti-slip effect. At this time, the state of the anti-slip ring 3 can be seen in Figure 2 A2 in .

[0061] When in use, when the connected part passes through the hollow structure of the gland 4 and the cavity 11 of the connecting tube 1, it is either tightly connected to the hollow structure of the gland 4, or tightly connected to the cavity 11 of the connecting tube 1, or tightly connected to the hollow structure of the gland 4 and the cavity 11 of the connecting tube 1 at the same time to achieve the connection purpose. Then, after the gland 4 and the connecting tube 1 are fixed in place, the anti-slip ring 3 can be squeezed to prevent the connected part from slipping. The anti-slip process is specifically as follows:

[0062] As the gland 4 gradually penetrates into the connecting pipe 1 and squeezes the locking ring 3, the locking ring 3 gradually undergoes radial deformation. The locking ring 3 is initially a conical cylindrical ring structure (see Figure 2 A1 in ), and then gradually transforms into a ring with a planar structure (see Figure 2 A2 in the figure), so that the inner end of the anti-slip ring 3 (i.e., the end where the anti-slip teeth 31 are located) will gradually become smaller. At this time, if the connected part is a flexible pipe, the anti-slip teeth 31 will penetrate the outer wall of the flexible pipe; if the connected part is a rigid pipe, the anti-slip teeth 31 will squeeze and produce a great friction force, thereby achieving the effect of clamping and anti-slip.

[0063] Specifically, the hole diameter of the anti-slip shoulder 13 is greater than or equal to the inner diameter of the gland 4 .

[0064] Specifically, a first clamping structure for tightening with a wrench is provided on the outside of the connecting pipe 1, which is preferably a planar structure arranged on both sides of the outer wall of the connecting pipe 1; a second clamping structure for tightening with a wrench is provided on the outside of the pressure cover 4, which is preferably a hexagonal structure arranged at the outer end of the pressure cover 4 (similar to the tightening end structure of a bolt).

[0065] Specifically, both ends of the connecting pipe 1 are respectively provided with the above-mentioned anti-slip shoulders 13 and the pressure cap 4 .

[0066] Specifically, the connecting pipe 1 and the gland 4 are threadedly connected. However, this is not limited thereto, and the connecting pipe 1 and the gland 4 may also be connected by bolts, screws or other connecting structures, which are not specifically limited in the present invention.

[0067] Furthermore, a relief groove 15 is provided between the anti-slip shoulder 13 and the thread 14 for accommodating the anti-slip ring which is radially deformed after being axially squeezed.

[0068] Third specific embodiment

[0069] See also Figures 3 to 7 , Figure 3 It is an exploded view of the assembly of the anti-slip assembly provided in the third specific embodiment of the present invention; Figure 4 A partial cross-sectional view of the anti-slip assembly provided in the third specific embodiment of the present invention; Figure 5 A partial cross-sectional view of a connecting pipe provided in a third specific embodiment of the present invention; Figure 6 A partial cross-sectional view of a sealing ring provided in a third specific embodiment of the present invention; Figure 7 This is a schematic diagram of the position structure of the sealing ring provided in the third specific embodiment of the present invention when it is in two different states.

[0070] The third specific embodiment of the present invention provides an anti-slip assembly, which includes the anti-slip ring provided in the first specific embodiment of the present invention and the connecting assembly provided in the second specific embodiment of the present invention.

[0071] Furthermore, the anti-slip assembly also includes a sealing ring 2, and a sealing groove 12 for accommodating the sealing ring 2 is provided in the connecting pipe 1 in the connecting assembly. After assembly, the sealing ring 2, the anti-slip ring and the end cover 4 are arranged in sequence from inside to outside along the axial direction of the connecting pipe 1.

[0072] Further, the sealing groove 12 is a tapered groove (whose cross section is roughly wedge-shaped), wherein:

[0073] The end of the tapered groove away from the end cover 14 has a larger aperture and is provided with a limiting boss 16;

[0074] The end of the tapered groove close to the end cover 14 has a smaller aperture and is adjacent to the anti-slip shoulder 13;

[0075] The axial length of the tapered groove is greater than the axial length of the sealing ring 2 , so that the sealing ring 2 has an axial displacement space greater than zero in the sealing groove 12 .

[0076] Furthermore, if Figure 4 , Figure 6 and Figure 7 As shown, a V-shaped groove 22 is provided at the inner end of the sealing ring 2 .

[0077] Specifically, the outer wall of the sealing ring 2 can fit with the bottom of the sealing groove 12, that is, the contact surfaces of the sealing ring 2 and the sealing groove 12 have similar shapes and also form tapered side walls (or wedge-shaped).

[0078] When using:

[0079] When the connected part is inserted into the anti-slip assembly, the sealing part of the sealing ring 2 will be deformed to a certain extent. Since the V-shaped groove 22 is provided, the deformation will be relatively easy.

[0080] In the initial state (or the normal state without external force), the inner diameter of the anti-slip ring 3 is larger than the outer diameter of the connected part, and the extension direction of the anti-slip teeth 31 is close to the insertion direction of the connected part, so that the connected part can be easily inserted;

[0081] Tighten the gland 4, which forces the locking ring 3 to deform (the state changes from Figure 2 A1 in the figure becomes A2), the deformed anti-slip teeth 31 will apply a clamping force to the outer wall of the connected member, so that the connected member can be prevented from moving outward, that is, the anti-slip effect is achieved;

[0082] When the sealing ring 2 loses its elasticity due to long-term compression, the connected part will gradually separate from the anti-detachment assembly (if the connected part is a pipe fitting, it will be subjected to outward pressure exerted by the fluid in the pipeline), thereby generating an axial displacement outward (the V-groove on the sealing ring 2 can increase the pressure-bearing area at this time). At this time, under the action of the conical sealing groove, the sealing ring 2 produces radial contraction, thereby preventing the sealing ring 2 from losing its elasticity and causing sealing failure.

[0083] Specifically, the sealing ring 2 is preferably made of rubber.

[0084] Specifically, in the above-mentioned anti-slip assembly, a pressure cover 4, an anti-slip ring, an anti-slip shoulder 13, a sealing groove 12 and a sealing ring 2 can be respectively provided at both ends of the connecting pipe 1, so that the two connected parts can be sealed and connected at the two ends of the anti-slip assembly through the anti-slip assembly, and the anti-slip effect can be achieved respectively.

[0085] Alternatively, the gland 4, the anti-slip ring, the anti-slip shoulder 13, the sealing groove 12 and the sealing ring 2 may be provided at only one end of the connecting pipe 1 to seal the connecting pipe 1 and the connected part and achieve the anti-slip effect.

[0086] It should be noted here that the anti-slip ring, connecting assembly and anti-slip assembly provided by the present invention can not only be used to connect straight pipe fittings, but also can be applied to connecting elbows, tees, reducers, etc., and can also be applied to connecting structures such as valves and pipe fittings. Moreover, the anti-slip ring, connecting assembly and anti-slip assembly provided by the present invention have very good anti-slip effect and sealing effect when connecting fluid conveying pipe fittings. However, the present invention is not only suitable for connecting fluid conveying pipe fittings, but also can be applied to the anti-slip connection and sealing connection of other connecting parts, such as solid cables. The present invention does not specifically limit the structural dimensions of the connected parts.

[0087] Fifth specific embodiment

[0088] The fifth specific embodiment of the present invention provides a connecting pipe, comprising a first connecting pipe and a second connecting pipe for conveying fluid, the first connecting pipe and the second connecting pipe are connected by the anti-slip assembly provided in the fourth specific embodiment of the present invention. The first connecting pipe and the second connecting pipe are the connected parts mentioned above.

[0089] Specifically, the first connecting pipe and the second connecting pipe can be flexible pipes such as PE (polyethylene) pipes or PVC (Polyvinyl chloride) pipes, or connected parts of other structural sizes.

[0090] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
