Description

Technical Field

[0001] The present invention relates to a hydraulic pipe, in particular to a labeled pipe; in addition, it also relates to an engineering machine having the labeled pipe and a label arrangement method. Background Art

[0002] Hydraulic systems are widely used in engineering machinery and other industrial equipment. Hose assemblies are commonly used auxiliary devices in hydraulic systems to transmit hydraulic power or transport high-pressure media such as water, gas, and oil to ensure liquid circulation and transfer liquid energy.

[0003] As a spare part with a limited life cycle, the hose assembly needs to be permanently labeled with its model, specification, production date and other attribute information to facilitate quality traceability or component replacement.

[0004] Usually, the hose assembly is attached with a label paper, which records important information such as the corresponding hose assembly's connector size, hose type and size, and installation type. However, once the label paper is damaged and falls off, or the label ink fades and the writing becomes blurred, it will cause inconvenience to the user and subsequent maintenance. Therefore, the reasonable arrangement of the label paper on the hose assembly has become one of the important items for hose manufacturers to control product quality.

[0005] At present, one label arrangement method used in hose assemblies is the self-adhesive label pasting method, in which, for example Figure 1 As shown, the label is made of a self-adhesive label paper 1a made of paper coated with self-adhesive, and the label information is displayed by ink spraying. The self-adhesive label paper 1a is directly attached to the surface of the hydraulic hose 2a; however, the self-adhesive label paper 1a itself has poor adhesive performance. Under the harsh working conditions of outdoor operations, the self-adhesive label paper 1a is prone to debonding, causing the self-adhesive label paper to fall off; for this reason, it is necessary to wrap a transparent tape on the surface of the label, which can be reinforced, but the appearance is untidy and the image is poor. Moreover, if Figure 3 As shown, a sheath 3a is usually required to be installed on the outside of the hydraulic hose 2a, which causes the information on the label to be blocked and cannot be effectively identified.

[0006] For this purpose, the hose assembly adopts another label arrangement, such as Figure 2 As shown, a hole is punched on the label and a plastic tie 4a is used for bundling. However, this increases the cost of a single hose assembly and is not suitable for cost control during mass production. Moreover, the plastic tie 4a has a high rate of breakage and falling off under the action of external force. Once the plastic tie 4a falls off, the label will be lost, making the hose information unrecognizable.

[0007] Therefore, it is necessary to design a novel labeling tube to overcome or alleviate the above-mentioned technical problems. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a labeling tube, which can reduce the risk of label falling off, and can effectively reduce production costs and improve production efficiency.

[0009] A further technical problem to be solved by the present invention is to provide an engineering machine whose hydraulic pipe can reduce the risk of label falling off.

[0010] In addition, the technical problem to be solved by the present invention is to provide a label arrangement method, which can reduce the risk of labels falling off, and effectively reduce production costs and improve production efficiency.

[0011] In order to achieve the above object, the present invention provides a labeling tube, including a connecting tube assembly and a label, wherein the connecting tube assembly includes a connecting tube and a joint, and a fixed end of the label is fastened between a connecting end of the connecting tube and the joint.

[0012] Preferably, the joint comprises a pressing piece, and the pressing piece is tightly connected to the connecting end of the connecting pipe.

[0013] Specifically and preferably, the buckling piece includes an outer sleeve and a core, the connecting end of the connecting tube is fastened between the outer sleeve and the core, and the fixed end of the label is located between the connecting end of the connecting tube and the outer sleeve.

[0014] Furthermore, at least one buckling structure is axially arranged on the inner surface of the outer sleeve or the outer surface of the core.

[0015] Specifically, the buckling structure is an annular protrusion arranged circumferentially along the outer sleeve or the core, or a plurality of protrusions arranged at intervals in the circumferential direction.

[0016] Preferably, the outer sleeve or the core is fastened to the connecting tube via the buckling structure, and the fixed end of the label is located between the outer sleeve and the connecting tube.

[0017] Specifically and preferably, the end of the fixed end of the label is located between the first pressing structure on the outer sleeve close to the label and the connecting tube.

[0018] Specifically, the joint is threadedly connected to the connecting pipe.

[0019] Preferably, the label is a tamper-proof label.

[0020] The present invention also provides an engineering machinery, comprising the labeling tube described in any one of the above technical solutions.

[0021] In addition, the present invention also provides a label arrangement method, comprising the following steps: arranging the label at the connecting end of the connecting tube, and connecting the fixed end of the label to the connecting end of the connecting tube; assembling the joint, fastening the connecting end of the connecting tube to the joint, and positioning the end of the fixed end of the label between the connecting tube and the joint.

[0022] Preferably, the end of the fixed end of the label extends between the buckling structure on the outer sleeve of the connector and the connecting pipe.

[0023] Specifically and preferably, the end of the fixed end of the label extends between the first buckling structure on the outer sleeve close to the label and the connecting tube.

[0024] Specifically, the joint is connected to the connecting pipe by buckling.

[0025] Through the above technical solution, the beneficial effects of the present invention are as follows:

[0026] In the basic technical solution of the present invention, the fixed end of the label is arranged between the connecting pipe and the joint, so that the fixed end of the label is firmly fastened to both the connecting pipe and the joint without the risk of falling off. At the same time, the other end of the label can be a free end. In this way, when the outer surface of the connecting pipe is wrapped with a winding sheath, it is only necessary to flip the free end to the outer surface of the sheath to expose the label information to the outside for easy reading. Moreover, there is no need to punch holes in the label or use cable ties, which can reduce production costs and, to a certain extent, improve production efficiency.

[0027] In addition, the label can be an anti-damage label, which can be made of non-woven fabrics, for example, non-woven fabrics made of polyester fiber, polypropylene fiber (PP), polyester (PET), nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), polyvinyl chloride (PVC) and other materials. They are strong, tensile-resistant and fold-resistant, and the inkjet information on the label is stable and not easy to fade.

[0044] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In addition, in the description of the present invention, it is necessary to understand that the orientation terms are based on the labeling tube itself. For example, the outer sleeve 31 is arranged on the outside of the core 32, and relatively, the core 32 is arranged on the inside of the outer sleeve 31; the orientation or position relationship shown in the drawings is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] like Figure 4 and Figure 5 As shown, the labeling tube of the basic embodiment of the present invention includes a connecting tube assembly and a label 1, wherein the connecting tube assembly includes a connecting tube 2 and a joint 3, and the fixed end of the label 1 is fastened between the connecting end of the connecting tube 2 and the joint 3.

[0048] The present invention divides the two ends of the label 1 into a fixed end and a free end. The fixed end of the label 1 is arranged between the connecting end of the connecting tube 2 and the joint 3. By fastening the connecting end of the connecting tube 2 and the joint 3, the fixed end of the label 1 can be firmly fixed between the connecting tube 2 and the joint 3. At the same time, the free end of the label 1 can be flipped freely. Therefore, when it is necessary to wrap a sheath around the outside of the connecting tube 2, the free end of the label 1 can be flipped to expose the label information outside the sheath, which is convenient for staff to read the label information. In this way, not only can the label be effectively fixed to prevent the label 1 from falling off, but also the reading of the label information is not affected. There is no need to punch holes in the label 1 or tie it with a cable tie, which improves production efficiency. In particular, when mass production is carried out, the production cost can be effectively reduced.

[0049] Among them, the connecting pipe 2 can be a hose, such as a rubber hose, a silicone hose, etc. Specifically, the connecting pipe 2 can be composed of a three-layer structure including an inner rubber layer 21, a reinforcement layer 22 and an outer rubber layer 23. The inner rubber layer 21, the reinforcement layer 22 and the outer rubber layer 23 are arranged in sequence from the inside to the outside. The reinforcement layer 22 can be formed by materials such as steel wire to enhance the overall strength of the connecting pipe 2.

[0050] Furthermore, the connection end of the connecting pipe 2 and the joint 3 can be connected by crimping. Specifically, the joint 3 includes a crimping piece, which is tightly connected to the connection end of the connecting pipe 2.

[0051] Furthermore, the structure of the buckle piece is varied. For example, the buckle piece can be composed of a jacket 31 and a core 32. The connecting end of the connecting tube 2 is inserted into the gap formed between the jacket 31 and the core 32. At the same time, the fixed end of the label 1 is also inserted together with the connecting tube 2, so that the fixed end of the label 1 is located between the connecting end of the connecting tube 2 and the jacket 31. The connecting end of the connecting tube 2 is fastened to the jacket 31 and the core 32 by pressing, so that the fixed end of the label 1 is clamped between the connecting end of the connecting tube 2 and the jacket 31, so as to effectively fix the label 1. The buckle pressing method refers to: applying pressure through special equipment (such as a crimping machine) to shrink the size of the jacket 31 of the buckle piece to achieve the purpose of interference fit with the connecting tube 2, or to cause the jacket 31 and the connecting tube 2 to produce extrusion deformation to achieve a bite-locking relationship.

[0052] In a specific embodiment, a buckling structure can be provided on the inner surface of the outer sleeve 31, and the number of the buckling structures can be set as needed, so that the outer sleeve 31 is buckled together with the connecting end of the connecting pipe 2 through the buckling structure thereon to form a tight and sealed connection relationship; the buckling structure can be a protrusion or a groove, specifically, the buckling structure can be an annular protrusion arranged along the circumference of the outer sleeve 31, or the buckling structure can also be composed of a plurality of protrusions, each of which is arranged around the circumference of the outer sleeve 31 at intervals; of course, the buckling structure can also be arranged on the outer surface of the core 32, the buckling structure can be an annular protrusion arranged along the circumference of the core 32, or the buckling structure can also be composed of a plurality of protrusions, each of which is arranged around the circumference of the core 32 at intervals; the connecting pipe 2 is squeezed by the buckling structure, so that the outer sleeve 31, the connecting end of the connecting pipe 2 and the core 32 can be tightly connected to each other. Wherein, when the buckling structure is composed of a plurality of protrusions, the lengths of each protrusion along the circumference can be the same or different. In the above technical solution, the protrusion is taken as an example for explanation. Similarly, the protrusion can also be replaced with a groove, which can also achieve the same function as the protrusion.

[0053] In order to ensure the sealing between the joint 3 and the connecting tube 2, the fixed end of the label 1 may not completely cover all the buckling structures, that is, the fixed end of the label 1 may be buckled together with part of the buckling structure close to the label 1, so that part of the buckling structure is directly buckled together with the connecting end of the connecting tube 2, and the other part of the buckling structure is buckled together with the connecting tube 2 through the fixed end of the label 1, which can not only effectively fasten the label 1, but also ensure the sealing. Preferably, the fixed end of the label 1 can be buckled only with the first buckling structure close to the label 1, where the "first buckling structure" refers to the buckling structure on the joint 3, which is arranged in sequence from one end close to the label 1 to the other end away from the label 1, and is located at the first position.

[0054] For another example, the buckling piece can also be a clamp, and the joint 3 can be a structure with only a core 32, so that the connecting end of the connecting pipe 2 is sleeved on the core 32, and an annular protrusion or an annular groove can be provided on the outer surface of the core 32 along the axial direction. The connecting pipe 2 and the joint 3 are fastened together by the clamp, and the fixed end of the label 1 can be provided between the clamp and the connecting pipe 2, or the fixed end of the label 1 can also be provided between the connecting pipe 2 and the joint 3, which can also effectively fasten the label 1 while ensuring the sealing.

[0055] In addition, the connecting pipe 2 can also be a hard pipe, such as a metal pipe, etc. The joint 3 and the connecting pipe 2 can be threadedly connected and sealed by the thread structure; preferably, the joint 3 is sleeved on the connecting end of the connecting pipe 2, so that a part of the thread teeth is directly connected to the connecting end of the connecting pipe 2, and the other part of the thread teeth is connected to the connecting pipe 2 through the fixed end of the label 1, thereby effectively fastening the label 1 to prevent the label 1 from falling off; specifically, as Figure 6As shown, the joint 3 and the connecting pipe 2 are connected by a nut 4. In order to ensure the sealing between the joint 3 and the connecting pipe 2, a sealing ring 5 is arranged between the joint 3 and the connecting pipe 2, and the sealing ring 5 is limited by a sleeve 6 to prevent the sealing ring 5 from moving. Moreover, a protrusion is formed on the inner side surface of the nut 4 at the end close to the label 1, which limits the sleeve 6 on the one hand and tightens the fixed end of the label 1 on the other hand, wherein a thread can be arranged on the protrusion of the nut 4 and is threadedly connected to the connecting pipe 2 to achieve the tightening of the fixed end of the label 1; in addition, a transition joint 33 can also be arranged at the other end of the joint 3 so that it can be connected to the hydraulic equipment.

[0056] In order to prevent the label information on the label 1 from fading, an anti-damage label can be used. For example, the label 1 can be made of non-woven fabrics made of polyester fiber, polypropylene fiber, polyester fiber, nylon fiber, viscose fiber, acrylic fiber, polyethylene fiber, chloroprene fiber, etc., or other materials that can prevent fading and are strong and durable; in this way, even when used in outdoor conditions, the information sprayed on the label 1 is highly stable, not easy to fade, strong, tensile-resistant, fold-resistant, and durable.

[0057] In order to facilitate understanding of the technical concept and advantages of the labeling tube of the present invention, relatively preferred features and a relatively comprehensive structural form of the present invention are described below.

[0058] like Figure 4 and Figure 5 As shown, the labeling tube of the preferred embodiment of the present invention comprises a label 1, a connecting tube 2 and a joint 3, the joint 3 comprises a jacket 31 and a core 32, the connecting end of the connecting tube 2 is inserted into the gap between the jacket 31 and the core 32, the fixed end of the label 1 is inserted into the gap between the jacket 31 and the core 32 together with the connecting end of the connecting tube 2, the inner surface of the jacket 31 is provided with a plurality of buckling structures along the axial direction, the buckling structures can be annular protrusions arranged along the circumference of the jacket 31 or a plurality of protrusions arranged at intervals along the circumference; by buckling the joint 3 and the connecting tube 2, one end of the label 1 is fastened between the connecting tube 2 and the jacket 31; preferably, the end of the fixed end of the label 1 is located between the first buckling structure on the jacket 31 close to the label 1 and the connecting tube 2. Wherein, the label 1 is made of non-woven fabric.

[0059] The fixed end of the label 1 is inserted into the gap between the outer sleeve 31 and the core 32 together with the connecting tube 2. After the buckling operation, the fixed end of the label 1 can be fastened between the connecting tube 2 and the outer sleeve 31 without the risk of falling off. There is no need to punch holes on the label 1 or use cable ties, which effectively reduces production costs and improves production efficiency. Moreover, only one end of the label 1 is buckled and the other end is a free end. When the connecting tube 2 needs to be wrapped with a sheath, the free end of the label 1 can be flipped to expose the information on the label 1 to the outside of the sheath for easy reading. In addition, non-woven fabric is used to make the label 1, and the inkjet information on the label 1 is highly stable, not easy to fade, strong, tensile-resistant, and fold-resistant, and durable.

[0060] The buckle connection between the label 1 and the hose of the present invention was subjected to aging test, burst test and pulse test of not less than 150,000 times according to the national standard GBT 7939-2008 hydraulic hose assembly test method, and achieved good test results.

[0063] Assemble the joint, and fasten the connecting end of the connecting tube 2 to the joint 3 , and make the end of the fixed end of the tag 1 located between the connecting tube 2 and the joint 3 .

[0064] By adopting the above method, one end of the label 1 is inserted into the joint 3 together with the connecting tube 2, and after the buckling operation, the label 1 and the connecting tube 2 can be firmly fastened together without the risk of falling off. At the same time, only one end of the label 1 is buckled, and the other end is a free end. When the connecting tube 2 needs to be wrapped with a sheath, the free end of the label 1 can be turned over to expose the information on the label 1 to the outside of the sheath for easy reading.

[0065] In order to firmly connect the connecting tube 2 with the joint 3, a plurality of buckling structures are arranged axially on the inner surface of the outer sleeve 31 of the joint 3 or the outer surface of the core 32.

The buckling operation is performed to firmly connect the connecting tube 2 with the joint 3, and to tightly fix the label 1 with the connecting tube 2 without falling off.

[0066] Preferably, the end of the fixed end of the tag 1 extends between the first buckling structure on the outer sleeve 31 close to the tag 1 and the connecting tube 2, so as to achieve better sealing between the connecting tube 2 and the joint 3.

[0067] As a preferred embodiment of the label arrangement method of the present invention, the following steps are included:

[0068] Cutting: Cut the connecting pipe 2 to a suitable length as required;

[0069] Paste the label: paste the label 1 on one end of the connecting tube 2, and ensure that one end of the label 1 is pasted in the corresponding length area of ​​the first buckling structure of the connecting end of the connecting tube 2 and the outer sleeve 31 of the connector 3, and the other end of the label 1 is a free end and is not pasted;

[0070] Assemble the connector: ensure that the first pressing structure of the outer sleeve 31 of the connector 3 presses the label 1;

[0071] Crimping the joint: Use special equipment (such as a crimping machine) to press the joint 3 and the connecting pipe 2 to a suitable size to complete the fastening connection between the label 1, the connecting pipe 2 and the joint 3.

[0072] The label arrangement method of the present invention can effectively fasten the label 1 without punching holes in the label 1 or using cable ties, thereby reducing production costs and effectively improving production efficiency.
