Description

Technical Field

[0001] The utility model relates to the technical field of fluid transmission and processing, in particular to a hot-melt adhesive hose with multiple bearings that is conducive to multi-angle spraying. Background Art

[0002] With the continuous development of industrial technology, hot melt adhesive spraying technology has been widely used in various fields due to its efficient and convenient bonding properties.

[0003] In practical applications, the traditional hot melt hose design faces limitations due to its straight shape and lack of flexibility, such as:

[0004] 1. In the field of automobile maintenance, when a vehicle suffers from scratches, collisions or other forms of damage, it is usually necessary to repair and spray the damaged parts locally. It is relatively difficult to spray the traditional linear hot melt hose accurately to the target position without disassembling the entire component. Not only does it increase the complexity and cost of repairs, but it may also bring additional risks due to potential damage to other parts of the vehicle during disassembly and reinstallation.

[0005] 2. In the field of furniture renovation, problems such as wear, scratches or fading in the use of furniture also need to be partially repaired and sprayed. In addition, when the shape and structure of furniture are diverse, traditional hot melt hoses are difficult to adapt to these complex working environments, thus affecting the spraying effect and maintenance efficiency.

[0006] 3. Similar problems also exist in the fields of building restoration, ship maintenance, and aircraft maintenance. The working environment in these fields is usually limited in space and complex and changeable, and traditional linear hot melt hoses are often unable to cope with them.

[0007] Therefore, how to facilitate hot melt adhesive spraying in a space-constrained or complex working environment has become a technical problem to be solved by the present utility model. Utility Model Content

[0008] The technical problem solved by the utility model is to provide a hot melt hose with multiple bearings that is conducive to multi-angle spraying in view of the defects existing in the above-mentioned prior art, so as to solve the problem raised in the above-mentioned background technology that traditional hot melt hoses are not conducive to adapting to complex working environments due to their straight shape and lack of flexibility in the fields of automobile repair, furniture renovation, construction, shipbuilding, and aircraft maintenance.

[0009] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0010] A hot melt adhesive hose with multiple bearings that is conducive to multi-angle spraying, comprising a first tube body, a second tube body, a first pipeline connecting bearing, a third tube body, a second pipeline connecting bearing, a first elastic thin tube and a second elastic thin tube;

[0011] The first tube body and the second tube body are connected via a first pipe connecting bearing, and the second tube body and the third tube body are connected via a second pipe connecting bearing;

[0012] The center lines of the first tube body, the second tube body and the third tube body are not on the same straight line so that the first tube body has a certain angle relative to the second tube body and the third tube body respectively;

[0013] A first elastic thin tube is sleeved on the outer side of the first pipeline connection bearing and located at the connection position between the first pipeline and the second pipeline;

[0014] A second elastic thin tube is sleeved on the outer side of the second pipeline connecting bearing and located at the connecting position of the second pipeline and the third pipeline.

[0015] As a further solution of the utility model, the inner side surface of the first elastic thin tube is tightly matched with the first pipeline, the second pipeline and the first pipeline connecting bearing respectively.

[0016] As a further solution of the utility model, the inner side surface of the second elastic thin tube is tightly matched with the second pipeline, the third pipeline and the second pipeline connecting bearing respectively.

[0017] As a further solution of the utility model, the first elastic thin tube and the second elastic thin tube are made of silicone rubber or polyurethane material with elasticity and wear resistance.

[0018] As a further solution of the present invention, the thickness of the first elastic thin tube and the second elastic thin tube is between 0.5 mm and 2 mm.

[0019] As a further solution of the utility model, the diameters of the first tube body, the second tube body and the third tube body are equal.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. Enhanced flexibility and adaptability: By introducing the structural design of the first elastic thin tube and the second elastic thin tube, the hot melt hose of the present application can be easily bent and inserted in a complex environment. This flexibility enables the hot melt hose to adapt to changes in various angles and shapes, thereby solving the problem that traditional hot melt hoses are easily restricted when bending or inserting. This improvement not only improves work efficiency, but also reduces the difficulty of operation.

[0022] 2. Improve structural stability: The cooperation between the elastic thin tube, the pipeline and the connecting bearing increases the friction resistance at the pipeline connection, making it difficult for the hot melt hose to rotate accidentally during operation. It is beneficial for it to change its angle in complex environments only when it is subject to resistance limited by the environment, so as to adapt to the needs of relatively complex environments.

[0039] The diameters of the first tube body 1, the second tube body 2 and the third tube body 3 are equal.

[0040] Embodiment 1:

[0041] This embodiment provides a hot melt hose with multiple bearings that is conducive to multi-angle spraying, including a first tube body 1, a second tube body 2, and a third tube body 3. These tube bodies are connected to each other through a first pipe connecting bearing 6 and a second pipe connecting bearing 7. The key innovation is that the center lines of the first tube body 1, the second tube body 2, and the third tube body 3 are not on the same straight line, so that the first tube body 1 has a certain angle relative to the second tube body 2 and the third tube body 3, respectively, thereby enhancing the flexibility and bendability of the hot melt hose.

[0042] In addition, a first elastic thin tube 4 is provided outside the first pipe connection bearing 6, at the connection position between the first pipe 1 and the second pipe 2. Similarly, a second elastic thin tube 5 is provided outside the second pipe 2 connection bearing 7, at the connection position between the second pipe 2 and the third pipe 3. These elastic thin tubes are made of silicone rubber with a thickness of about 1 mm, which not only ensures sufficient elasticity to adapt to the exploration in complex environments, but also provides the necessary structural strength.

[0043] During the automobile maintenance process, when it is necessary to spray the external parts of the vehicle such as the bumper and side skirt locally, the maintenance personnel can use the hot melt hose provided in this embodiment. Since the hot melt hose has multiple sections of pipe body and multiple pipe connection bearings, it can be easily bent and sprayed to the target position without disassembling the parts. At the same time, the design of the elastic thin tube enables the hot melt hose to remain stable when bent, and is not easy to rotate by mistake, and this bending refers to between the first pipe body 1 and the second pipe body 2, between the second pipe body 2 and the third pipe body 3, or between the first pipe body 1 and the third pipe body 3, and between these three pipe bodies. During the exploration process, when two or three of them touch the inner wall of the complex environment respectively, the angle conversion between them is conducive to self-correction and adaptation to the needs of this complex environment; and the structure of the utility model is only more conducive to the use of complex environments relative to the existing straight pipe structure, but not very suitable for any unlimited complex environment, and all belong to the implementation methods known to ordinary technicians in the field.

[0044] Similarly, in the field of furniture renovation, when the furniture has problems such as wear and scratches, the hot melt hose provided in this embodiment can also be used for local spraying. Similarly, since the hot melt hose has high flexibility and bendability, it can easily adapt to various shapes and structures of furniture to achieve accurate spraying.

[0045] The hot melt hose with multiple bearings that facilitates multi-angle spraying provided by this embodiment not only greatly improves the accuracy and efficiency of spraying, but also reduces the difficulty and cost of the maintenance process. At the same time, this technology also fills the gap in the prior art and brings substantial progress and convenience to industrial production in automobile maintenance, furniture renovation and other related fields.

[0046] Embodiment 2:

[0047] The present embodiment relates to the field of fluid transmission and processing in mechanical engineering, and in particular to the working principle of a hot melt hose with multiple bearings that is conducive to multi-angle spraying and its key component, an elastic thin tube.

[0048] On the basis of Example 1, this example further describes in detail the working principle of the first elastic thin tube 4 and the second elastic thin tube 5 and their functions in the hot melt adhesive tube.

[0049] The hot melt hose comprises a first tube body 1, a second tube body 2 and a third tube body 3, which are connected to each other via a first pipe connecting bearing 6 and a second pipe connecting bearing 7. In order to achieve flexible application of the hot melt hose in space-constrained or complex environments, especially in local spraying operations in the fields of automobile repair, furniture renovation, etc., this embodiment sets an elastic thin tube at a key connection position.

[0050] Specifically, the outer side of the first pipe connection bearing 6, located at the connection position of the first pipe and the second pipe, is sleeved with a first elastic thin tube 4. The inner side of the first elastic thin tube 4 is tightly matched with the first pipe, the second pipe and the first pipe connection bearing 6, respectively, to form a relatively fixed connection structure. Similarly, the outer side of the second pipe connection bearing 7, located at the connection position of the second pipe and the third pipe, is also sleeved with a second elastic thin tube 5, and the inner side of the tube is tightly matched with the second pipe, the third pipe and the second pipe connection bearing 7, respectively.

[0051] When the hot melt hose needs to be bent or inserted in a complex environment, the first elastic thin tube 4 and the second elastic thin tube 5 can be squeezed and deformed within a certain angle through the elastic deformation ability of their materials. This deformation allows the hot melt hose to change its direction or angle when passing through a narrow space or bypassing an obstacle. At the same time, due to the close fit between the elastic thin tube, the pipeline and the connecting bearing, they can maintain the overall structural stability and sealing of the hot melt hose during the deformation process.

[0052] In addition, the presence of the elastic thin tube also increases the friction resistance at the pipe connection, making it relatively difficult for the first pipe and the second pipe, and the second pipe and the third pipe to rotate by mistake under the action of the connecting bearing. This stability is essential for accurately controlling the spraying direction and preventing accidental operation.

[0053] During the automobile maintenance process, for example, when spraying parts in the engine compartment, the traditional straight hot melt hose is difficult to adapt to the narrow space and dense parts. The hot melt hose with an elastic thin tube provided in this embodiment can be easily bent and stably probed into the target position for spraying.

[0054] The same is true in the field of furniture renovation. When it is necessary to spray hard-to-reach areas such as corners and grooves of furniture, the hot melt hose of this embodiment can easily adapt to changes in various shapes and structures through the deformation ability of the elastic thin tube, achieving a uniform and accurate spraying effect.

[0055] It can be seen from the detailed description of this embodiment that the first elastic thin tube 4 and the second elastic thin tube 5 play a key role in the hot melt adhesive hose. They not only enhance the flexibility and adaptability of the hot melt adhesive hose through their own elastic deformation ability, but also improve the stability of the pipeline connection by increasing the friction resistance. These advantages make the hot melt adhesive hose provided by this embodiment more practical and reliable in complex working environments.

[0056] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical 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. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0057] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
