Description

Technical Field

[0001] This utility model belongs to the field of wire harness processing and manufacturing technology, and in particular relates to a telescopic device and its wire harness installation device. Background Technology

[0002] In the wire harness manufacturing process, wire harnesses typically need to be fixed to mounting plates to ensure neat, stable, and safe wiring. However, due to the varying lengths, diameters, and layout requirements of different wire harness specifications, the positioning and tension of the wire harness often need to be adjusted during installation to avoid overstretching or slack, thereby ensuring the reliability and lifespan of the wire harness. Existing fixing methods usually involve manual adjustment using cable ties, clamps, or other fasteners, but these methods suffer from numerous problems, including being time-consuming, difficult, inconsistent, inaccurate, and lacking adaptability.

[0003] Therefore, a support fork has been developed in the existing technology and set on the wire harness mounting plate to support the wire harness and prevent it from falling. However, since the wire harnesses have different directions, the fixed support fork may sometimes obstruct the direction of the wire harness. If it is temporarily removed, it will take a lot of time. When the support fork is needed later, it will take a lot of time to reinstall it.

[0004] Therefore, how to provide a telescopic device that enables rapid switching between telescopic states, is simple to operate, has a compact structure, and can quickly adjust the installation height of the wiring harness is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To solve at least one of the above-mentioned technical problems, the present invention provides a telescopic device, comprising: a mounting base, a limiting component, and a locking component;

[0006] The mounting base is provided with a sliding cavity that extends through the mounting base;

[0007] The limiting component includes: a pusher head disposed at a first end, a limiting block disposed at a second end, and a limiting groove disposed between the first end and the second end; wherein the width of the pusher head and the limiting block are both greater than the width of the sliding cavity.

[0008] The locking component is rotatably mounted on one side of the sliding cavity and has a locking groove that corresponds to the groove edge of the limiting groove.

[0009] Furthermore, the mounting base also includes: a rotating groove disposed on one side of the sliding cavity;

[0010] The locking component is rotatably mounted within the rotating groove.

[0011] Furthermore, the mounting base also includes a mounting interface disposed on one side of the mounting base along the telescopic direction of the limiting component.

[0012] Furthermore, dustproof sealing rings are provided at the inlet and outlet positions of the sliding cavity.

[0013] Furthermore, the limiting groove includes several limiting slots arranged along the sliding direction of the limiting component; the pusher is movably disposed at the first end of the limiting component.

[0014] Furthermore, the locking slot includes: a first locking slot and a second locking slot;

[0015] The first locking slot and the second locking slot are symmetrically arranged on both sides of the locking component.

[0016] Furthermore, the first locking groove, and / or the second locking groove, is a "V" shaped groove; the pusher is a wedge shape corresponding to the "V" shaped groove.

[0017] Furthermore, the telescopic device also includes an elastic element disposed between the pusher and the mounting base, surrounding the limiting component.

[0018] Furthermore, the telescopic device also includes: a branch fork disposed at the second end of the limiting component; the branch fork is provided with branch teeth.

[0019] A telescopic device includes: a wire harness mounting plate and any one of the above-mentioned telescopic devices disposed on the wire harness mounting plate;

[0020] Telescopic device used to support the wiring harness to be installed.

[0021] In this embodiment, a telescopic device is provided. When the operator performs telescopic operation on the telescopic device, he directly pushes the first end or the second end of the limiting component, causing the limiting component to slide in the sliding cavity of the mounting base. When the push head abuts against the locking component, it can make the locking component rotate flexibly. In the first state, the limiting block in the limiting assembly is located at the outlet of the sliding cavity. Because the width of the limiting block is greater than the width of the sliding cavity, the limiting assembly cannot move further. At this time, the second end of the limiting assembly is in a fully retracted state. In the second state, the operator acts on the first or second end of the limiting assembly to push the limiting assembly to move and extend within the sliding cavity. After the push head abuts against the first position of the locking assembly, it pushes the locking assembly to rotate in the first direction. When the push head reaches the sliding cavity, because the width of the push head is greater than the width of the sliding cavity, the push head cannot continue to move forward. At this time, the first end of the locking groove rotates into the limiting groove, and the second end of the locking groove is located above the top edge of the limiting groove. Then, the operator retracts the limiting assembly, and the side of the limiting groove abuts against and pushes the first end of the locking groove. The locking assembly rotates in the second direction, and the second end of the locking groove abuts against the top edge of the limiting groove. The groove on the locking assembly engages with the groove edge formed by the top edge and side edge of the limiting groove, preventing the limiting assembly from continuing to retract and slide. At this time, the second end of the limiting assembly is in a fully extended state. Understandably, the operator only needs to continue pushing the limiting component outwards. The limiting groove on the limiting component moves with the limiting component, and the pusher on the limiting component abuts against the second position of the locking component, pushing the locking component to rotate in the first direction. The second end of the locking groove of the locking component also rotates into the limiting groove, and the locking component releases the locking state of the limiting component. At this time, the groove of the locking component disengages from the groove edge formed by the top and side edges of the limiting groove, restoring a free rotation state, and the limiting component can slide freely in the sliding cavity. The operator returns the locking component to the initial state and retracts the limiting component, so that the locking device returns from the second state to the first state. In this embodiment, a telescopic device is provided. The operator can complete the telescopic device by directly applying force to both ends of the limiting component. The telescopic state can be quickly switched without complicated tools or other additional operations, which greatly improves the telescopic efficiency. When the telescopic device is used for wire harness installation, placing the wire harness at the second end of the limiting component can quickly adjust the installation height of the wire harness. In summary, this application provides a telescopic device that realizes rapid switching between telescopic states, and is simple to operate, compact in structure, and can quickly adjust the installation height of the wire harness.

[0028] This utility model provides a telescopic device, for reference. Figure 1 and Figure 2 It includes: mounting base 1, limit component 2 and locking component 3;

[0029] Mounting base 1 is provided with a sliding cavity that extends through mounting base 1;

[0030] The limiting component 2 includes: a pusher 21 disposed at a first end, a limiting block disposed at a second end, and a limiting groove 22 disposed between the first end and the second end; wherein the width of the pusher 21 and the limiting block is greater than the width of the sliding cavity.

[0031] The locking component 3 is rotatably disposed on one side of the sliding cavity and has a locking groove corresponding to the groove edge of the limiting groove 22.

[0032] In this embodiment, a telescopic device is provided. When the operator performs telescopic operation on the telescopic device, he directly pushes the first end or the second end of the limiting component, causing the limiting component to slide in the sliding cavity of the mounting base. When the push head abuts against the locking component, it can make the locking component rotate flexibly. In the first state, the limiting block in the limiting assembly is located at the outlet of the sliding cavity. Because the width of the limiting block is greater than the width of the sliding cavity, the limiting assembly cannot move further. At this time, the second end of the limiting assembly is in a fully retracted state. In the second state, the operator acts on the first or second end of the limiting assembly to push the limiting assembly to move and extend within the sliding cavity. After the push head abuts against the first position of the locking assembly, it pushes the locking assembly to rotate in the first direction. When the push head reaches the sliding cavity, because the width of the push head is greater than the width of the sliding cavity, the push head cannot continue to move forward. At this time, the first end of the locking groove rotates into the limiting groove, and the second end of the locking groove is located above the top edge of the limiting groove. Then, the operator retracts the limiting assembly, and the side of the limiting groove abuts against and pushes the first end of the locking groove. The locking assembly rotates in the second direction, and the second end of the locking groove abuts against the top edge of the limiting groove. The groove on the locking assembly engages with the groove edge formed by the top edge and side edge of the limiting groove, preventing the limiting assembly from continuing to retract and slide. At this time, the second end of the limiting assembly is in a fully extended state. Understandably, the operator only needs to continue pushing the limiting component outwards. The limiting groove on the limiting component moves with the limiting component, and the pusher on the limiting component abuts against the second position of the locking component, pushing the locking component to rotate in the first direction. The second end of the locking groove of the locking component also rotates into the limiting groove, and the locking component releases the locking state of the limiting component. At this time, the groove of the locking component disengages from the groove edge formed by the top and side edges of the limiting groove, restoring a free rotation state, and the limiting component can slide freely in the sliding cavity. The operator returns the locking component to the initial state and retracts the limiting component, so that the locking device returns from the second state to the first state. In this embodiment, a telescopic device is provided. The operator can complete the telescopic device by directly applying force to both ends of the limiting component. The telescopic state can be quickly switched without complicated tools or other additional operations, which greatly improves the telescopic efficiency. When the telescopic device is used for wire harness installation, placing the wire harness at the second end of the limiting component can quickly adjust the installation height of the wire harness. In summary, this application provides a telescopic device that realizes rapid switching between telescopic states, and is simple to operate, compact in structure, and can quickly adjust the installation height of the wire harness.

[0033] Preferred, Reference Figure 1 The mounting base 1 also includes: a rotating groove 11 disposed on one side of the sliding cavity;

[0034] The locking component 3 is rotatably mounted in the rotating groove 11.

[0035] In this embodiment, a rotating groove is added to the mounting base, in which the locking component can be stably embedded and rotated, preventing the locking component from shifting due to improper installation or external force, thereby improving the stability and reliability of the overall structure of the rotating device and thus increasing the service life of the rotating device.

[0036] Preferred, Reference Figure 1 The mounting base 1 also includes: a mounting interface 12 disposed on one side of the mounting base and extending along the telescopic direction of the limiting component 2.

[0037] In this embodiment, an installation interface is added on one side of the mounting base along the telescopic direction of the limiting component. On the one hand, it can easily fix the telescopic device to external equipment or structure, such as brackets, frames, wire harness mounting plates or other mechanical devices, to achieve fast and stable installation. On the other hand, the direction of the installation interface is consistent with the telescopic movement, which helps to better counteract the force generated by the movement of the limiting component, so that the device can be more firmly fixed when subjected to tensile or compressive forces, avoiding loosening or misalignment.

[0038] Preferably, dustproof sealing rings are provided at the inlet and outlet positions of the sliding cavity to prevent external impurities from entering the sliding cavity, which could cause excessive wear or jamming of the limiting and sliding components, thereby extending the lifespan of the telescopic device and improving its long-term operational reliability to meet the needs of use in complex environments.

[0039] Preferably, the limiting block and the pusher 21 are provided with elastic buffers to reduce the impact force when the limiting block and the pusher 21 contact the mounting base, extend the service life of the device, and reduce the noise generated during operation.

[0040] Preferred, Reference Figure 1 The limiting groove 22 includes several limiting grooves arranged along the sliding direction of the limiting component; the push head 21 is movably arranged at the first end of the limiting component 2.

[0041] In this embodiment, the limiting groove includes several limiting slots arranged along the sliding direction of the limiting component. Each limiting slot corresponds to a preset locking position. The operator adjusts the position of the push head on the limiting component to adjust the distance between the push head and the locking component, so that the locking component can be precisely engaged at the groove edge of the preset limiting slot, allowing the limiting component to accurately stop at multiple preset locking positions to meet the needs of different extension lengths. Optionally, the limiting component is provided with a linear slide groove, in which the push head can be slidably arranged and locked in the slide groove by a threaded knob. Unscrewing the threaded knob can adjust the position of the push head in the linear slide groove; tightening the threaded knob can lock the specific position of the push head. It is worth noting that the depth, width, spacing, and number of the limiting slots can be arbitrarily set by those skilled in the art as needed.

[0042] Preferred, Reference Figure 2 The locking slot includes: a first locking slot 31 and a second locking slot 32;

[0043] The first locking groove 31 and the second locking groove 32 are symmetrically arranged on both sides of the locking component 3.

[0044] In this embodiment, when the locking component is unlocked, the operator directly retracts the limiting component, and the second end of the first locking groove enters the limiting groove. Under the push of the groove edge side, it rotates along the first direction to the symmetrical position of the initial state. Since the first locking groove and the second locking groove are symmetrically arranged on both sides of the locking component, the state of the locking component is completely consistent with the initial state. The operator does not need to return the locking component to the initial state, which greatly reduces the extra operation steps and makes the use of the telescopic device simpler and more intuitive, especially improving work efficiency when frequently switching telescopic states.

[0045] Preferred, Reference Figure 1 and Figure 2 The first locking groove 31, or / and the second locking groove 32, are “V” shaped grooves; the pusher 21 is a wedge shape corresponding to the “V” shaped groove.

[0046] In this embodiment, when the wedge-shaped pusher enters the first or second locking groove, it gradually contacts the inclined surfaces on both sides of the "V"-shaped groove, making the pusher push the locking assembly more smoothly. When the first or second locking groove engages with the groove edge of the limiting groove, the side and top of the groove edge fit against the two sides of the "V"-shaped groove, forming surface contact, which greatly enhances the locking effect of the locking assembly; at the same time, it can distribute the force on the locking assembly to both sides, enabling the first or second locking groove to withstand a larger load, greatly improving the reliability and applicability of the telescopic device.

[0047] Preferred, Reference Figure 1 The telescopic device also includes an elastic element 4 disposed between the push head 21 and the mounting base 1, surrounding the limiting component 2.

[0048] In this embodiment, an elastic element is added to the telescopic device. In the second state, when the operator pushes the limiting component to extend within the sliding cavity, the pre-tightened elastic element is compressed. When the pusher reaches the sliding cavity, the pre-tightening force of the elastic element pushes the limiting component back, causing the side of the limiting groove to abut against and push the first end of the locking groove. The locking component rotates in the second direction, and the second end of the locking groove abuts against the top edge of the limiting groove, thus completing the engagement between the locking groove and the limiting groove. On one hand, the pre-tightening force of the elastic element makes the engagement between the locking groove and the limiting groove tighter, preventing loosening caused by external forces or vibrations. On the other hand, the elastic element allows the locking process to be completed naturally without additional operation, reducing the operator's workload.

[0049] Preferably, the telescopic device further includes: a branch fork disposed at the second end of the limiting component 2; the branch fork is provided with branch teeth.

[0050] In this embodiment, a branching fork is added to the telescopic device. When the telescopic device is used for wire harness installation, the branching teeth on the branching fork separate multiple wire harnesses at fixed intervals, preventing the wire harnesses from tangling together. This ensures that the wire harnesses remain neat and tidy during installation and telescopic movement, thereby improving the installation efficiency. It is worth noting that the spacing, spatial direction, and number of the branching teeth can be arbitrarily set by those skilled in the art.

[0051] A wire harness mounting device includes: a wire harness mounting plate and any one of the above-mentioned telescopic devices disposed on the wire harness mounting plate;

[0052] Telescopic device used to support the wiring harness to be installed.

[0053] This implementation provides a wire harness installation device; a wire harness mounting plate for installing and testing the wire harness to be installed, and a telescopic device supported on the wire harness mounting plate; the wire harness to be installed is located at the second end of the telescopic device's limiting component. Through the extension and retraction of the telescopic component, the installation height of the wire harness can be quickly and flexibly adjusted, ensuring that the wire harness maintains the optimal height position during installation and testing, greatly improving the efficiency of wire harness installation and testing. Importantly, the telescopic device extends during use to support the wire harness to be installed; when not in use, it retracts to avoid obstructing the wire harness from swinging in a preset direction, eliminating the need for temporary disassembly or assembly, greatly reducing time and labor intensity. Specifically, the number of telescopic devices and their arrangement on the wire harness mounting plate can be set by those skilled in the art as needed to meet the installation requirements of different types of wire harnesses to be installed. When changing the type of wire harness to be installed, only the extension and retraction state of the telescopic device on the mounting plate needs to be adjusted to adapt to different installation height requirements of the wire harness, thereby improving the applicability of the wire harness installation device.

[0054] The aforementioned wire harness installation device is based on the aforementioned telescopic device, and its technical effects and combinations of technical features will not be elaborated further here. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
