Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for installing sealing rings, specifically to an auxiliary tooling and fixture for installing lamp sealing rings. Background Technology

[0002] When assembling a lamp, the cable entry point needs to be sealed with a sealing ring. Therefore, the reliability of the seal at the cable entry point is an important factor in determining the quality of the entire lamp.

[0003] One existing method for installing sealing rings is manual assembly. This involves aligning the sealing ring with the sealing groove on the light fixture and pressing it into the groove with your fingers. While this method doesn't rely heavily on tools, it requires workers to use one hand to hold the sealing ring against the light fixture and pull the wire with the other, forcing the sealing ring into the sealing groove under pressure. This method demands a high level of skill from the worker, as it requires ensuring the sealing ring remains coaxial with the sealing groove throughout the pressing process.

[0004] Another installation method involves assembling the lamp housing using a benchtop pressure bar fixture: the lamp housing is fixed to the workbench, and the sealing ring is pressed into the stop from top to bottom using a vertical pressure bar. While this method ensures coaxiality, it relies entirely on a rigid external support, resulting in a large and heavy assembly that cannot be used in high-altitude lamp posts, confined underground pits, or explosion-proof chambers. Furthermore, the fixed stroke of the pressure bar leaves no room for applying force to the pre-installed cable or the single-sided open lamp port, leading to installation failure.

[0005] Therefore, the existing technology lacks an auxiliary tooling that can complete the sealing ring press-fitting with one hand within a single open port. Utility Model Content

[0006] The purpose of this utility model is to address the problems existing in the prior art by providing an auxiliary tooling and fixture for installing lamp sealing rings.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an auxiliary tooling for installing a lamp sealing ring, including a plastic substrate, a wire channel housing provided above the plastic substrate, the wire channel housing being made of lightweight metal, a lead channel for guiding cables being provided on the inner wall of the wire channel housing, and a press-fit semi-plane being provided at one end of the wire channel housing along its length direction.

[0008] In the above technical solution, when the sealing ring needs to be installed, the worker can place the wire in the lead-in channel of the wire tray housing, so that the sealing ring abuts against the pressing half-plane. Then, the worker pulls the wire, which moves the lamp. The sealing ring enters the sealing groove under the joint pressure of the lamp and the pressing half-plane. During this process, the worker can align the sealing ring with the sealing groove with one hand and pull the wire with the other hand, thereby reducing the difficulty of pressing the sealing ring. Moreover, this solution does not require the lamp to be fixed on the workbench, so it is more convenient to move the lamp. There is no need for fixing and disassembly steps, and there is no need to adopt a large-volume design, which reduces equipment costs and improves the ease of use.

[0009] The plastic substrate supports the cable tray housing and raises the cable tray housing, making it easier for users to install the sealing ring on the lamp using the cable tray. Because the cable tray housing is made of lightweight metal, it can improve the tensile strength of the cable tray housing while ensuring that the overall weight of the tooling is not too large. The lead wire channel is used to guide and support the wire, making it convenient for the wire to be placed.

[0010] Preferably, the plastic matrix is ​​made of modified polypropylene, polyethylene, or ABS.

[0011] Preferably, the material of the cable tray housing is one of aluminum alloy, magnesium alloy, and titanium alloy.

[0012] Preferably, the cable tray housing is fixedly connected to the plastic substrate via a transition support plate.

[0013] Preferably, one side of the transition support plate is flush with the end face of the wire groove housing away from the press-fit semi-plane, forming a continuous transition.

[0014] Preferably, a solid lubricating layer is provided on the inner wall of the wire groove housing.

[0015] A press-fit housing is detachably installed on the cable tray housing. One end face of the press-fit housing is aligned with the press-fit half-plane, and the press-fit housing and the cable tray housing are joined to form a press-fit full-plane.

[0016] Preferably, a press-fit housing is detachably installed on the cable tray housing, with one end of the press-fit housing aligned with one end of the cable tray housing.

[0017] Preferably, the top of the cable tray housing is provided with a slot, and the bottom of the press-fit housing is provided with a tongue that inserts into the slot.

[0018] Preferably, the wire channel housing and the press-fit housing are connected by a magnetic chuck.

[0019] This utility model also provides a tooling fixture, including the lamp sealing ring installation auxiliary tooling as described in any one of the above, including a fixture body, wherein the lamp sealing ring installation auxiliary tooling is installed on the fixture body.

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

[0021] 1. This lamp's sealing ring installation auxiliary tooling allows the operator to place the wire in the lead-in channel of the wire tray housing when installing the sealing ring, making the sealing ring abut against the pressing half-plane. Then, pulling the wire moves the lamp, and the sealing ring enters the sealing groove under the combined pressure of the lamp and the pressing half-plane. During this process, the operator can align the sealing ring with the sealing groove with one hand and pull the wire with the other, thus reducing the difficulty of pressing the sealing ring. Furthermore, this solution does not require fixing the lamp to the workbench, making it easier to move the lamp. It eliminates the need for fixing and disassembly steps and does not require a large-volume design, reducing equipment costs and improving ease of use.

[0022] 2. This lamp's sealing ring installation auxiliary fixture has a plastic base that supports the wire channel housing and raises it, making it easier for users to install the sealing ring on the lamp using the wire channel. Because the wire channel housing is made of lightweight metal, it can improve the tensile strength of the wire channel housing while ensuring that the overall weight of the fixture is not too large. The lead wire channel is used to guide and support the wire, making it convenient for wire placement.

[0023] 3. The auxiliary tooling for installing the sealing ring of this lamp has a solid lubricating layer that can reduce the coefficient of friction between the cable and the inner wall of the housing, reduce surface wear of the cable during repeated pulling and pulling, and is especially suitable for the protection of flexible cables or precision cables; the lubricating layer also has wear-resistant properties, which can extend the service life of the cable tray housing, while maintaining long-term stable low friction performance and reducing maintenance requirements.

[0024] 4. The auxiliary tooling for installing the sealing ring of this lamp has a detachable design that allows for the installation and removal of the press-fit housing, making it easy to place the wire into the cable tray housing and the press-fit housing. The end alignment structure ensures that the press-fit housing and the cable tray housing form a complete press-fit plane, avoiding tilting or deformation of the sealing ring due to positioning deviation during the press-fit process, thus improving the sealing assembly accuracy. At the same time, since the press-fit housing and the cable tray housing together form a complete press-fit plane, when pressing the sealing ring, only the wire needs to be pulled once to install the sealing ring on the lamp, without the need to rotate the sealing ring and the lamp for secondary press-fit.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figures 1 to 5 The lamp sealing ring installation auxiliary tooling in this solution includes a plastic base 1, a wire groove housing 2 on the plastic base 1, the wire groove housing 2 is made of lightweight metal, and a press-fit semi-plane 21 is provided at one end of the wire groove housing 2 along its length direction. The cross section of the wire groove housing can be U-shaped, V-shaped, semi-circular or other shapes.

[0033] In the above technical solution, when the sealing ring needs to be installed, the worker can place the wire in the lead-in channel of the wire tray housing 2, so that the sealing ring abuts against the pressing half-plane 21. Then, the worker can pull the wire, which will move the lamp. The sealing ring will enter the sealing groove under the pressure of the lamp. During this process, the worker can align the sealing ring with the sealing groove with one hand and pull the wire with the other hand, thereby reducing the difficulty of pressing the sealing ring. Moreover, this solution does not require the lamp to be fixed on the workbench, so it is more convenient to move the lamp. There is no need for fixing and disassembly steps, and there is no need to adopt a large-volume design, which reduces the equipment cost and improves the ease of use.

[0034] The plastic substrate 1 is used to support the wire channel housing 2. At the same time, the plastic substrate 1 can raise the wire channel housing 2, so that the user can use the wire channel to install the sealing ring on the lamp. Since the wire channel housing 2 is made of lightweight metal, it can improve the tensile strength of the wire channel housing 2 while ensuring that the overall weight of the tooling is not too large. The lead wire channel is used to guide and support the wire, making it convenient for the wire to be placed.

[0035] The plastic matrix 1 is made of modified polypropylene, polyethylene or ABS.

[0036] In the above technical solution, since the plastic matrix 1 does not need to rub against the wire, the requirement for tensile strength is low. It only needs to meet the requirements of light weight and low price. ABS is an acrylonitrile-butadiene-styrene copolymer, which is a recyclable material. After it is scrapped, it can be crushed and reused, which meets the requirements of green manufacturing.

[0037] The material of the cable tray housing 2 is one of aluminum alloy, magnesium alloy and titanium alloy.

[0038] In the above technical solutions, aluminum alloy, magnesium alloy and titanium alloy have low density, are lightweight metals, and have high tensile strength, which can meet the requirements of tensile strength and light weight of the wire trough housing 2.

[0039] The cable tray housing 2 is fixedly connected to the plastic substrate 1 through the transition support plate 3, and the upper end face of the transition support plate 3 is connected to the cable tray housing 2.

[0040] In the above technical solution, when the tooling and other components of this solution are integrated on the same base, the height of the other components is equivalent to the working height of this solution. The height provided by the plastic substrate 1 is insufficient to create a height difference between the wire groove housing 2 and other components, thus facilitating the installation of the sealing ring onto the lamp. The transition support plate 3 can further raise the wire groove housing 2, creating a height difference between the wire groove housing 2 and other components, thus facilitating the user to install the sealing ring onto the lamp.

[0041] Please refer to Figure 1 and Figure 2 One side of the transition support plate 3 is flush with the end face of the wire groove housing 2 away from the press-fit half-plane 21, forming a continuous transition.

[0042] In the above technical solution, when the user holds the wire and pulls it axially, their thumb and forefinger can directly abut against the continuous, flat load-bearing end face formed by the transition support plate 3 and the wire channel housing 2. This end face provides a rigid reaction fulcrum in the axial direction, keeping the tension vector coaxial with the compression direction of the sealing ring, avoiding lateral force causing the sealing ring to twist or local overload; at the same time, the leverage effect reduces the torque on the wrist, reducing operator fatigue. The continuous transition eliminates the sharp edges of the steps, preventing stress concentration on the hand and the risk of scratches, thus improving assembly safety.

[0043] A solid lubricating layer 4 is provided on the inner wall of the cable tray housing 2.

[0044] In the above technical solution, the solid lubricating layer 4 can reduce the friction coefficient between the cable and the inner wall of the housing, reduce the surface wear of the cable during repeated pulling and retraction, and is especially suitable for the protection of flexible cables or precision cables; the lubricating layer also has wear-resistant properties, which can extend the service life of the cable tray housing 2, while maintaining long-term stable low friction performance and reducing maintenance requirements.

[0045] Working method: Attach the sealing ring to the wire, ensuring it is tightly fitted to the mounting part of the lamp. Then place the wire in the lead-in channel of the wire guide housing 2, and place the sealing ring against one end of the wire guide housing 2. Pull the wire, causing the wire and lamp to slide relative to the sealing ring. The lower half of the sealing ring is pressed into the lamp under the pressure of the wire guide housing 2. After that, release the wire and rotate the sealing ring and lamp to align the unpressed half of the sealing ring with the wire guide housing 2. Pull the wire again, and the other half of the sealing ring is pressed into the lamp, completing the pressing of the sealing ring.

[0046] Please refer to Figures 2 to 4 A press-fit housing 5 is detachably installed on the cable tray housing 2. The end face of one end of the press-fit housing 5 is aligned with the press-fit half-plane 21. The press-fit housing 5 and the cable tray housing 2 are connected to form a press-fit full-plane.

[0047] In the above technical solution, the detachable design enables the installation and removal of the press-fit housing 5, thereby facilitating the insertion of the wire into the wire channel housing 2 and the press-fit housing 5; the end alignment structure ensures that the press-fit housing 5 and the wire channel housing 2 form a complete press-fit plane, avoiding tilting or deformation of the sealing ring due to positioning deviation during the press-fit process, improving the sealing assembly accuracy. At the same time, since the press-fit housing 5 and the wire channel housing 2 together form a complete press-fit plane, when pressing the sealing ring, only the wire needs to be pulled once to install the sealing ring on the lamp, without the need to rotate the sealing ring and the lamp for secondary press-fit.

[0048] It should be noted that the cross-section of the press-fitted housing 5 can also be U-shaped, V-shaped, semi-circular, or other shapes.

[0049] Working method: The wire is placed into the lead channel of the wire tray housing 2, and then the pressing housing 5 is installed on the wire tray housing 2, so that the wire tray housing 2 and one end of the pressing housing 5 form a complete pressing plane. Then, the wire is pulled, and the wire drives the lamp to squeeze the sealing ring. The sealing ring can be pressed into the lamp in only one pressing.

[0050] In some embodiments, such as Figure 3 As shown, the top of the cable tray housing 2 has a slot 7, and the bottom of the press-fit housing 5 has a tongue 6 that inserts into the slot 7. In the above technical solution, the precise fit between the slot 7 and the tongue 6 enables rapid positioning of the press-fit housing 5, ensuring consistent installation.

[0051] In other embodiments, such as Figure 4 As shown, the cable tray housing 2 and the pressing housing 5 are connected by a magnetic chuck 8. The magnetic chuck 8 includes a first magnet 801 mounted on the cable tray housing 2 and a second magnet 802 mounted on the pressing housing 5. In the above technical solution, the magnetic connection method simplifies the loading and unloading operation, eliminates the need for additional fasteners, and provides a stable connection force to prevent the semi-ring from shifting during the pressing process.

[0052] Please refer to Figure 5 The present invention also provides a tooling fixture, including any of the above-mentioned lamp sealing ring installation auxiliary tooling, including a fixture body 9, wherein the lamp sealing ring installation auxiliary tooling is installed on the fixture body 9.

[0053] In the above solution, the lamp sealing ring installation auxiliary tooling can be integrated into the fixture body 9, thereby facilitating the user to use the lamp sealing ring installation auxiliary tooling and other types of fixtures at the same time.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
