Description

Technical Field

[0001] This utility model relates to the field of transmission connection components technology, and more specifically, to a connecting component. Background Technology

[0002] Connecting components are often used in various mechanical devices for transmission. For example, in a circular guide rail conveyor mechanism, adjacent sliders are connected by connecting components to form a circular conveyor chain. A drive mechanism drives one or more sliders to move, and the sliders are transmitted through the connecting components to realize the movement of the entire circular conveyor chain. The path of the circular guide rail conveyor mechanism includes straight segments and curved segments. During the movement of the circular conveyor chain, the distance between the sliders will change to a certain extent. If the two ends of a fixed-length connecting component are rotatably connected to a slider, a jam will occur when switching between the straight segment and the curved segment, affecting the smooth movement.

[0003] To address this, existing technologies propose introducing local elastic expansion components into the connecting members to meet the requirements of varying spacing between the connected components. However, existing connecting members are integrally molded, and the elastic expansion components are prone to failure or defects due to frequent deformation, which necessitates the replacement of the entire connecting member, increasing production costs and affecting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting member that solves the problem of needing to replace the entire connecting member when the elastic expansion component fails or is defective. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0005] A connecting member includes: a first component and a second component, the first component being provided with a first connecting end, the second component being provided with a second connecting end, and an elastic telescopic member being detachably connected between the first component and the second component.

[0006] In this component, to clarify the specific structure of the elastic expansion member, the elastic expansion member includes a first elastic member and a second elastic member. The first end of the first elastic member is connected to component one, and the second end of the first elastic member is connected to component two. The first end of the second elastic member is connected to component two, and the second end of the second elastic member is connected to component one. When component one and component two move relative to each other, the elastic deformation states of the first elastic member and the second elastic member are opposite.

[0007] To facilitate accurate control of the elastic expansion and contraction direction of the elastic expansion member, preferably, the first elastic member and the second elastic member are arranged along the line connecting component one to component two.

[0008] To define a detachable connection structure for the elastic expansion joint to ensure stable connection, the elastic expansion joint is engaged with component one and component two respectively. When engaged, no additional materials such as fasteners, inserts, or adhesives are required; the elastic expansion joint is simply inserted directly between component one and component two. The shape of the elastic expansion joint is flexible and can be adjusted according to the spacing requirements of the connected components.

[0009] Preferably, the elastic telescopic component includes a block-shaped main body made of flexible material, with engaging portions provided at both ends of the block-shaped main body, and engaging grooves provided on component one and component two to cooperate with the engaging portions.

[0010] To clarify the structural form of the elastic expansion member, it is described as having a corrugated shape. One end of the elastic expansion member is detachably connected to component one, and the other end is detachably connected to component two. In this structure, the wavelength, amplitude, wall thickness, and overall length in the wavelength direction of the elastic expansion member are set according to specific needs, so that the elastic coefficient and telescopic stroke of the connecting components can flexibly meet different requirements.

[0011] Preferably, component one is provided on both sides of component two to facilitate the connection of this connecting member to a mechanism such as an annular guide rail conveying mechanism to form an annular conveying chain structure.

[0012] During the use of this connecting component, foreign objects may enter the interior of the connecting component. Preferably, a baffle is introduced, which is connected to component one or component two and covers the elastic telescopic component.

[0013] To allow for elastic expansion and contraction in a predetermined guiding direction and to ensure the required spacing between connected components, a guiding mechanism is provided along the line connecting the first and second connecting ends. The guiding mechanism includes a guide rod and a guide hole, one of which is located on component one and the other on component two. The guide rod and the guide hole are slidably engaged.

[0014] When there are precise requirements for limiting the extension and retraction stroke of the connecting component, and the connecting component needs to extend and retract within a limited range, the guide rod is provided with a limiting part that limits the movement in the guiding sliding direction.

[0015] The beneficial effects of this utility model are:

[0016] In this connecting component, the parts are detachable. When parts one, parts two, and the elastic telescopic component experience local structural failure or defects, the parts can be easily disassembled and replaced, avoiding the need to replace or scrap the entire component. This extends the service life of the parts and significantly reduces production costs. When this connecting component is applied to a ring guide rail conveying mechanism, parts one are respectively set on both sides of parts two. Connecting end one can connect with the slider in the ring guide rail conveying mechanism, and connecting end two can cooperate with the drive mechanism in the ring guide rail conveying mechanism. Adjacent sliders in the ring guide rail conveying mechanism are connected by the connecting component to form a ring conveying chain. Compared with the existing ring guide rail conveying mechanism that only drives the slider to move, this connecting component has more and more uniform contact points with the slider, which can accurately reset to ensure precise spacing between connected parts. The structure is simple, compact, strong, and stable.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0033] like Figure 1 and Figure 2 As shown, a connecting member includes: component 1 and component 2. Component 1 is provided with a connecting end 11, and component 2 is provided with a connecting end 2 12. An elastic telescopic member 3 is detachably connected between component 1 and component 2.

[0034] In this connecting component, the parts are detachable. When parts 1, 2, and the elastic expansion member 3 experience local structural failures or defects, the parts can be easily disassembled and replaced locally, avoiding the need to replace or scrap the entire component. This extends the service life of the parts and greatly reduces production costs.

[0035] This connecting component can be used in a ring guide rail conveying mechanism. Component 1 is provided on both sides of component 2, wherein connecting end 11 can connect with the slider in the ring guide rail conveying mechanism, and connecting end 12 can cooperate with the drive mechanism in the ring guide rail conveying mechanism. Specifically:

[0036] like Figure 10 and Figure 11 As shown, adjacent sliders 70 in the annular guide rail conveying mechanism are connected by connecting members to form an annular conveying chain. Specifically, for the connecting members, the connecting end 11 of one component 1 is rotatably connected to the previous slider 70, and the connecting end 11 of the other component 1 is rotatably connected to the next slider 70. A driving part 71 that cooperates with the driving mechanism is provided on the slider 70, and a driving part 72 that cooperates with the driving mechanism is provided on the connecting end 12. The driving part 71 and the driving part 72 are preferably rollers. The driving mechanism drives the driving part 71 and the driving part 72 on the slider 70 simultaneously to make the annular conveying chain move.

[0037] In a preferred embodiment, the driving mechanism can be a rotating drive wheel at the arc segment of the guide rail of the annular guide rail conveying mechanism. The rotating drive wheel is provided with push arms that cooperate with the first drive part 71 and the second drive part 72 respectively. When the rotating drive wheel rotates, it drives the annular conveying chain to move in a circular motion. By simultaneously driving the slider 70 and the connecting member, the slider 70 can pass through the arc segment of the guide rail more smoothly and quickly, thereby improving the travel speed and conveying efficiency.

[0038] In this connecting component, on the one hand, since the elastic expansion member 3 is elastically arranged between the first component 1 and the second component 2, this component can elastically expand and contract to adapt to the spacing change requirements of the first component 1 and the second component 2. Moreover, when the first component 1, the second component 2 and the elastic expansion member 3 suffer structural failure or defects, it is convenient to disassemble and replace them, avoiding the need to replace the entire component.

[0039] On the other hand, compared with the existing ring guide rail conveying mechanism that only drives the slider 70 to move, this connecting component has more and more uniform mating parts with the slider 70, which can accurately reset to ensure that there is a precise distance between the connected parts. The structure is simple, compact, strong and stable.

[0040] like Figure 3As shown, when there is relative movement between component 1 and component 2, a guiding mechanism is provided in the direction of the line connecting the first connection end 11 and the second connection end 12 to guide the movement position of the components. The guiding mechanism includes a guide rod 41 and a guide hole 42. One of the guide rod 41 and the guide hole 42 is provided on component 1 and the other is provided on component 2. The guide rod 41 and the guide hole 42 are slidably engaged. At this time, the component can elastically expand and contract in the preset guiding direction to ensure the spacing change requirements of the connected components.

[0041] Furthermore, when there are precise requirements for limiting the extension and retraction stroke of the connecting member, and the connecting member needs to extend and retract within a limited range, the guide rod 41 is provided with a limiting part 43 that limits the movement in the guiding sliding direction.

[0042] The specific structure of the guide rod 41 can be as follows: the guide rod 41 can be in the form of a T-shaped rod, the head of the T-shaped rod is set as a limiting part 43, the component 1 is provided with a T-shaped groove, the opening of the T-shaped groove is the guide hole 42, the head of the T-shaped rod is inserted into the T-shaped groove, when the connecting component is extended, the limiting part 43 abuts against the step at the guide hole 42 to achieve limiting, when the connecting component is compressed, the limiting part 43 abuts against the bottom of the T-shaped groove to achieve limiting.

[0043] like Figure 4 and Figure 5 As shown, in this connecting component, to clarify the specific structure of an elastic expansion member 3, it specifically includes: the elastic expansion member 3 includes a first elastic member 31 and a second elastic member 32. The first end of the first elastic member 31 is connected to component 1, and the second end of the first elastic member 31 is connected to component 2. The first end of the second elastic member 32 is connected to component 2, and the second end of the second elastic member 32 is connected to component 1. When there is relative movement between component 1 and component 2, the elastic deformation states of the first elastic member 31 and the second elastic member 32 are opposite.

[0044] Preferably, the first elastic element 31 and the second elastic element 32 are arranged along the line connecting component 1 to component 2, in which case the direction of elastic stretching deformation is easy to control accurately.

[0045] To ensure the connection stability of different components, an extension portion one is provided on the side where component 1 is located towards component 2, and an extension portion two is provided on the side where component 2 is located towards component 1. The first end of the first elastic member 31 is connected to the main body of component 1, and the second end of the first elastic member 31 is connected to one side of the extension portion two. The first end of the second elastic member 32 is connected to the other side of the extension portion two, and the second end of the second elastic member 32 is connected to the extension portion one. The first elastic member 31 and the second elastic member 32 are arranged along the line connecting component 1 and component 2. When component 1 moves away from component 2, the first elastic member 31 undergoes tensile deformation under the tension of the main body of component 1, and the second elastic member 32 undergoes compressive deformation under the pressure of the extension portion one. That is, the elastic deformation states of the first elastic member 31 and the second elastic member 32 are opposite.

[0046] When component 1 approaches component 2, the first elastic element 31 undergoes compressive deformation under the pressure of the main body of component 1, and the second elastic element 32 undergoes tensile deformation under the tension of extension 1. That is, the elastic deformation states of the first elastic element 31 and the second elastic element 32 are opposite.

[0047] To guide the movement of the components, in the above structure, such as Figure 4 and Figure 5 As shown, a guiding mechanism can be provided in the line direction connecting the first connecting end 11 and the second connecting end 12 to perform elastic expansion and contraction deformation in a preset guiding direction, so as to ensure the spacing change requirements of the connected components.

[0048] In this connecting component, to clarify a detachable connection structure of the elastic telescopic member 3, the elastic telescopic member 3 is respectively engaged with component 1 and component 2; when engaged, no additional materials such as fasteners, plugs, or adhesives are needed, and the elastic telescopic member 3 is simply inserted directly between component 1 and component 2. The shape of the elastic telescopic member 3 is free and can be set according to the spacing requirements of the connected components.

[0049] like Figures 2 to 5 In the illustrated embodiment, the elastic telescopic member 3 includes a block-shaped main body made of flexible material. Each end of the block-shaped main body has a locking portion, and the first component 1 and the second component 2 are provided with locking grooves that mate with the locking portions. The flexible material can be rubber, silicone, etc. The locking portion can have a structure with a large head and a small base, specifically a T-shaped or dovetail structure. Correspondingly, the locking groove has a structure with a wide bottom and a narrow opening, specifically a T-shaped groove or a dovetail groove. To improve the elasticity of the elastic telescopic member 3 and enhance the elastic restoring ability of the connecting component, an elastic skeleton can be provided within the block-shaped main body made of flexible material.

[0050] In this connecting component, to clarify another detachable connection structure of the elastic telescopic member 3, the elastic telescopic member 3 is corrugated, wherein one end of the elastic telescopic member 3 is detachably connected to component 1, and the other end of the elastic telescopic member 3 is detachably connected to component 2. In this structure, the wavelength, amplitude, wall thickness, and overall length in the wavelength direction of the elastic telescopic member 3 are set according to specific needs, so that the elastic coefficient and telescopic stroke of the connecting component can flexibly meet different requirements.

[0051] In the above structure, the corrugated elastic telescopic member 3 can be fixed to component 1 and component 2 respectively by screws, or slots can be provided on component 1 and component 2, and the end of the corrugated elastic telescopic member 3 can be inserted into the slot to achieve connection.

[0052] like Figure 1 In one embodiment shown, two sets of corrugated elastic expansion members 3 are arranged side by side to perform elastic expansion and contraction deformation synchronously, further improving the reliability and stability of the expansion and contraction activities of component 1 and component 2.

[0053] The introduction of the corrugated elastic expansion member 3 allows the elastic expansion member 3 to undergo elastic deformation in its wavelength direction to achieve the change in the distance between the first connection end 11 and the second connection end 12. The corrugated elastic expansion member 3 has a compact structure and good stability, which helps to make the distance between the parts to be connected more accurately meet the requirements.

[0054] The elastic expansion member 3 is corrugated, specifically including one or a combination of rectangular wave shape, triangular wave shape, sine wave shape, and U-shaped wave shape.

[0055] Among them, rectangular and triangular wave shapes have larger bending angles and no transition area, while sine and U-shaped wave shapes have smooth transition areas. Rectangular and triangular wave shapes are less stable than sine and U-shaped wave shapes, so sine and U-shaped wave shapes are preferred.

[0056] When the elastic expansion member 3 is corrugated, its elastic deformation direction is not only in the wavelength direction, but also in the amplitude direction. That is, there will be relative yaw and torsional activity between the first connection end 11 and the second connection end 12. As a result, the overall expansion and contraction of the connecting component is not linear, but there will be a certain degree of torsion. Therefore, a guiding mechanism can be provided in the line direction connecting the first connection end 11 and the second connection end 12 for guiding. For example, the guiding mechanism includes a guide rod 41 and a guide hole 42. One of the guide rod 41 and the guide hole 42 is set on the first component 1, and the other is set on the second component 2. The guide rod 41 and the guide hole 42 are slidably engaged. At this time, the guiding sliding direction of the guide rod 41 and the guide hole 42 is along the wavelength extension direction of the elastic expansion member 3, ensuring that the first component 1 and the second component 2 can only accurately expand and contract relative to each other in a straight line.

[0057] like Figure 6 As shown, during the use of this connecting component, foreign objects may enter the interior of the connecting component. Therefore, a baffle plate 5 can be introduced. The baffle plate 5 is connected to component 1 or component 2. The baffle plate 5 covers the elastic telescopic component 3 to effectively prevent foreign objects from entering the gaps in the component connection, prevent dust accumulation inside the connecting component, and ensure that the connecting component can perform telescopic activities stably for a long time.

[0058] like Figure 7 As shown, in this connecting member, in order to protect the connecting member, a mounting shell 6 is wrapped around and connected to cover component 1 and component 2. In addition, the mounting shell 6 can also provide a mounting point for fixed connection of component 1 or component 2, such as fixing component 2 to the mounting shell 6. The elastic telescopic member 3 is detachably connected between component 1 and component 2, and component 1 moves relative to component 2.

[0059] like Figure 4 and Figure 5 As shown, two sets of elastic telescopic members are provided between component 1 and component 2. The first elastic member 31 and the second elastic member 32 of each elastic telescopic member are inserted into component 1 and component 2 in the same direction. That is to say, all the slots on component 1 and component 2 that are used to cooperate with the elastic telescopic member 3 have the same insertion direction.

[0060] like Figure 8The diagram shows a structure with multiple elastic telescopic components having different installation directions. The line connecting component 1 and component 2 is set as the reference X-axis direction. Two sets of elastic telescopic components 3 are arranged between component 1 and component 2. The first elastic element 31 and the second elastic element 32 of each elastic telescopic component 3 are arranged along the reference X-axis direction. Furthermore, the first elastic element 31 and the second elastic element 32 of one set of elastic telescopic components 3 are inserted into component 1 and component 2 along the Y-axis direction, and the first elastic element 31 and the second elastic element 32 of the other set of elastic telescopic components 3 are inserted into component 1 and component 2 along the Z-axis direction. That is to say, the slots on component 1 and component 2 for cooperating with the elastic telescopic components include different insertion directions. When the elastic telescopic components are engaged between component 1 and component 2 from different directions, they can be limited in different directions. Specifically, the first elastic component 31 and the second elastic component 32 inserted along the Y-axis can be limited in the Z-axis direction, while the first elastic component 31 and the second elastic component 32 inserted along the Z-axis can be limited in the Y-axis direction, effectively preventing misalignment and separation between component 1 and component 2 and improving the stability of the connecting components.

[0061] like Figure 9 As shown, only one component 1 can be connected to one component 2 to accommodate the varying spacing requirements between individual component 1 and individual component 2 in the corresponding mechanism.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
