Description

Technical Field

[0001] This utility model relates to the field of high-voltage discharge lamp technology, specifically a safety installation auxiliary device for high-voltage discharge lamps. Background Technology

[0002] During the installation of the high-pressure discharge lamp, the glass bulb part of the high-pressure discharge lamp needs to be passed through the reserved hole in the center of the reflector bowl, and finally the electrode pins at both ends are precisely fixed and electrically connected to the lamp holder of the base.

[0003] However, existing installation methods have significant technical flaws and safety risks. Because the glass bulb of a high-pressure discharge lamp is thin-walled and fragile, and the mounting holes of the reflector bowl typically have a small clearance with the outer diameter of the bulb, the bulb is highly susceptible to direct contact or friction with the edge of the reflector bowl's holes during installation. This contact easily leads to scratches and abrasions on the bulb surface.

[0004] In actual operation, even minor, unavoidable lateral impacts or pressure can cause the bulb to rupture at the point of damage, resulting in a "bulb explosion." Once the bulb explodes, the high-speed flying glass shards can cause irreversible scratches to the reflector's coating, rendering the entire reflector unusable and incurring high repair and replacement costs. More seriously, the flying glass fragments may pose a direct threat to the personal safety of on-site personnel, creating a safety hazard.

[0005] Therefore, the installation process of high-pressure discharge lamps in existing technologies requires high skill levels from operators, has a low margin for error, and is always accompanied by the risk of lamp damage and personal injury. There is an urgent need for an installation solution that can effectively prevent hard contact between the bulb and the reflector bowl during installation, thereby fundamentally eliminating scratches and lamp explosions. Utility Model Content

[0006] To address the technical problems in the background art, this utility model discloses an auxiliary device for the safe installation of a high-voltage discharge lamp.

[0007] This utility model provides a safety installation auxiliary device for high-voltage discharge lamps, including a sleeve; One end of the high-voltage discharge lamp is fixedly connected to one end of the sleeve; The sleeve covers the high-pressure discharge lamp, and there is a gap between the sleeve and the bulb of the high-pressure discharge lamp; The sleeve is inserted into the reflector bowl, and its other end abuts against the base; The other end of the high-voltage discharge lamp is fixedly connected to the base.

[0008] The high-voltage discharge lamp is directly connected to the sleeve, which results in a small operating space and high difficulty. Based on this, a further improvement is made: the present invention also includes a fixing plate; one end of the high-voltage discharge lamp is fixedly connected to the fixing plate; the fixing plate is fixedly connected to one end of the sleeve.

[0009] To facilitate the assembly and disassembly of the fixing plate and the sleeve, the following design is implemented: the fixing plate has a first threaded hole in the radial direction; one end of the sleeve has a radially extending through hole; the locking bolt passes through the through hole and is threadedly connected to the first threaded hole.

[0010] Because the first threaded hole and the through hole may be misaligned, the fixing plate needs to be rotated for adjustment. However, conventional fixing plates do not have gripping points, making it difficult to rotate the fixing plate. Based on this, a further improvement is made: a threaded gripping bolt is provided on the side of the fixing plate opposite to the high-voltage discharge lamp.

[0011] The high-voltage discharge lamp is located inside the sleeve, making it difficult to connect it accurately to the base. Therefore, a further improvement is made: the base is equipped with a locking platform; the other end of the sleeve is engaged with the locking platform.

[0012] If the high-voltage discharge lamp is already tightened on the base before the sleeve is engaged with the clamping platform, continuing to rotate the sleeve at this time will cause the high-voltage discharge lamp to explode. Based on this, the further modification is: when rotating the sleeve to engage with the clamping platform, the other end of the high-voltage discharge lamp is threadedly connected to the base and is in an untightened state.

[0013] The beneficial effects of this utility model are: the sleeve forms a reliable physical isolation between the bulb of the high-voltage discharge lamp and the mounting hole of the reflector bowl, ensuring that there is no hard contact or friction between the two during the entire installation process, thereby completely avoiding scratches and abrasions on the surface of the bulb. In addition, there is a gap between the sleeve and the bulb, so even if the sleeve is subjected to radial impact, the impact force will not act on the bulb, thus effectively protecting the bulb and preventing the bulb from breaking.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1 and Figure 2 As shown, and with Figure 1 For reference, this utility model discloses a safety installation auxiliary device for a high-voltage discharge lamp, including a cylindrical sleeve 1; the upper end of the sleeve 1 is provided with an inwardly protruding annular convex plate 102.

[0018] The upper end of the high-pressure discharge lamp 2 is provided with an axially protruding screw. The screw is inserted into the horizontally arranged fixing plate 5 and extends upward. The wing nut 8 located at the upper end of the fixing plate 5 is threadedly connected to this screw, thereby fixing the high-pressure discharge lamp 2 to the fixing plate 5. The inner diameter of the sleeve 1 is configured such that there is a gap between the inner wall of the sleeve 1 and the bulb of the high-pressure discharge lamp 2.

[0019] The diameter of the fixing plate 5 is larger than the inner diameter of the protruding plate 102 and slightly smaller than the inner diameter of the sleeve 1. The fixing plate 5 enters the sleeve 1 from the lower end and moves upward to abut against the lower end face of the protruding plate 102. The side of the fixing plate 5 is provided with a radially extending first threaded hole 51, and the upper end of the sleeve 1 is provided with a radially extending through hole 101. The locking bolt 6 passes through the through hole 101 from the outside to the inside and is threadedly connected to the first threaded hole 51, thereby realizing the connection and fixation between the fixing plate 5 and the sleeve 1. Compared with the direct fixed connection of the high-pressure discharge lamp 2 to the sleeve 1, the adapter setting of the fixing plate 5 has sufficient operating space and is easier to install.

[0020] The upper end of the fixed plate 5 is threaded with a gripping bolt 7 located inside the protrusion plate 102 and arranged vertically. The gripping bolt 7 provides a gripping point for the fixed plate 5. By fixing the gripping bolt 7 by hand, the fixed plate 5 can be driven to move up and down and rotate so that the fixed plate 5 rises to abut against the protrusion plate 102 so that the first threaded hole 51 is aligned with the through hole 101.

[0021] The base 4 is provided with an upwardly protruding locking platform 41 for engaging the lower end of the sleeve 1. This structure is used not only for the connection and positioning of the sleeve 1 and the base 4, but also for the connection and positioning of the high-pressure discharge lamp 2 and the base 4. After the sleeve 1 engages with the locking platform 41, rotating the sleeve 1 allows the screw at the lower end of the high-pressure discharge lamp 2 to be accurately threaded into the second threaded hole 42 on the base 4.

[0022] When the rotating sleeve 1 is engaged with the locking plate 41, the other end of the high-pressure discharge lamp 2 is threadedly connected to the second threaded hole 42 on the base 4 and is in a loose state. This setting can prevent the high-pressure discharge lamp 2 from being over-tightened to the base 4, which could cause the high-pressure discharge lamp 2 to explode.

[0023] The operation steps in this embodiment are as follows: S1. The screw at the upper end of the high-pressure discharge lamp 2 passes through the fixing plate 5 and is connected and fixed under the locking action of the wing nut 8; S2. Tighten the grab bolt 7 to the upper end of the fixing plate 5; S3. The grabbing bolt 7 passes through the lower end of the sleeve 1 upwards and drives the fixing plate 5 to abut against the lower end face of the protrusion plate 102. S4. By manually driving the gripping bolt 7 to move circumferentially, the position of the first threaded hole 51 is adjusted so that the first threaded hole 51 is aligned with the through hole 101. S5. Locking bolt 6 passes through through hole 101 and is threaded into first threaded hole 51; S6. Move the sleeve 1 so that the sleeve 1 engages with the protrusion on the upper side of the clamping table 41. S7. Drive the sleeve 1 to move towards the clamping table 41 until the screw at the lower end of the high-pressure discharge lamp 2 abuts against the upper end of the second threaded hole 42. S8. Rotate sleeve 1 so that the screw at the lower end of the high-pressure discharge lamp 2 is threadedly connected to the second threaded hole 42 until sleeve 1 abuts against the clamping platform 41. S9. Remove the wing nut 8 and take the sleeve 1 upwards to separate it from the high-voltage discharge lamp 2; S10. Tighten the screw at the lower end of the high-pressure discharge lamp 2 onto the base 4 to complete the installation of the high-pressure discharge lamp 2.

[0024] Compared with the prior art, the advantages of this embodiment are: the sleeve 1 forms a reliable physical isolation between the bulb of the high-voltage discharge lamp 2 and the mounting hole of the reflector bowl 3, ensuring that there is no hard contact or friction between the two during the entire installation process, thereby completely avoiding scratches and abrasions on the surface of the bulb. In addition, there is a gap between the sleeve 1 and the bulb, so even if the sleeve 1 is subjected to radial impact, the impact force will not act on the bulb, thereby effectively protecting the bulb and preventing the bulb from breaking.

[0025] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
