Description

Technical Field

[0001] The invention relates to the technical field of lamp installation, and in particular to a fixing structure of a lamp. Background Art

[0002] Work lights refer to lighting tools designed for various work scenarios, aiming to provide a stable, concentrated and comfortable light source. They are widely used in manufacturing workshops, maintenance stations, construction sites, outdoor activities, etc. With their high brightness, adjustable illumination angle, durability and shockproof features, work lights not only improve work efficiency and accuracy, but also ensure the safety of workers at night or in low-light environments. They are important auxiliary equipment in modern production and life.

[0003] For various usage scenarios, work lights need to have different characteristics. For example, in construction and high-vibration places, work lights need stronger shock resistance, but the existing threaded connection method is prone to loosening. Although additional measures such as using locking washers and applying thread lockers are usually taken to enhance the stability and firmness of the connection, these measures improve the reliability and durability of the connection by increasing the tightening force and bonding and solidification. However, the thread locker causes the threads of the nut and the screw to stick together, which makes it inconvenient to disassemble the threads and the nut, and it is easy to cause damage to the threads during disassembly. In a high-vibration environment, the nut and the screw will still move together, resulting in the problem of loose connection not being fundamentally solved. Based on this, the present invention purposely provides a fixing structure of a lamp that can fix the screw and the nut separately and can be disassembled and used repeatedly. Summary of the invention

[0004] The purpose of the present invention is to provide a fixing structure of a lamp in view of the deficiencies of the prior art, so as to solve the technical problems in the prior art.

The extrusion block is driven to move by a driving assembly arranged on it. The radii of the extrusion block and the extrusion cavity decrease upward along the axis direction of the first screw. The radius of the bottom end of the extrusion block is greater than the radius of the top end of the extrusion cavity. When the driving assembly drives the extrusion block to rise, the extrusion block causes multiple deformation blocks to expand outward, thereby tightening the nut, and at the same time, the driving assembly drives the plug block to be inserted into the groove through the locking assembly.

[0006] As a further solution of the present invention: the locking assembly includes a sliding block, an inclined groove, a transverse groove and a round rod, the sliding block is sleeved on the limit block, and the two are slidably connected, the inclined groove is opened on the sliding block, it is inclined, and its horizontal height away from one end of the first screw is higher than its horizontal height close to one end of the first screw, the transverse groove is opened on the limit block, the round rod is slidably installed in the transverse groove, one end of it is slidably installed in the inclined groove, and the other end is fixedly connected to the insert block, when the driving assembly drives the extrusion block to rise, the driving assembly drives the sliding block to rise.

[0007] As a further solution of the present invention: the driving assembly includes a second screw, a rotating block, a through hole and an insertion rod, the rotating block is rotatably installed in the through hole, the second screw is threadedly connected in the rotating block, and its bottom end is fixedly connected to the extrusion block, the through hole is opened at the top of the second screw, the insertion rod is slidably inserted on the sliding block, and it is slidably inserted with the through hole.

[0008] As a further solution of the present invention: the locking assembly further comprises a spring, the sliding block is connected to the top end of the limiting block via the spring, and the pre-tightening force of the spring causes the sliding block to move away from the limiting block.

[0009] As a further solution of the present invention: an end of the insert block close to the first screw is provided with an oblique angle, and the oblique angle is slidably matched with the bottom edge of the screw head of the first screw.

[0010] As a further solution of the present invention: a block with a groove is fixedly mounted on the sliding block, and a protrusion is fixedly mounted on the insertion rod. When the insertion rod passes through the sliding block and is inserted into the through hole, the protrusion is rotatably engaged with the block with the groove.

[0011] As a further solution of the present invention: a locking washer is sleeved on the threaded section of the first screw, and when the support seat is fixedly mounted on the mounting plate through the first screw, the locking washer is located between the nut and the mounting plate.

[0013] Beneficial effects of the present invention: 1. In the present invention, after the first screw and nut fix the support seat and the lamp body on the mounting plate, the driving component drives the extrusion block to rise, and the extrusion of the extrusion block causes the multiple deformation blocks to expand outward, thereby tightening the nut and improving the connection strength between it and the first screw. This connection method is convenient for disassembly and will not damage the threads of the first screw and the nut. While the driving component drives the extrusion block to rise, the driving component drives the insert block inside the limit block to be inserted into the groove through the locking component, thereby establishing a rigid connection between the first screw and the limit block on the support seat, avoiding the problem that the first screw itself loosens due to vibration and causes the overall connection strength to decrease; 2. In the present invention, through the design of the bevel, when installing the first screw, the first screw is directly installed along the limit block. At the beginning, the bottom edge of the screw head of the first screw will abut against the bevel, and as the first screw is pressed downward, the bottom edge of the screw head of the first screw will slide downward on the bevel, gradually squeezing the bevel into the cavity, thereby facilitating the installation of the first screw; 3. In the present invention, by setting the spring, the sliding block can be located away from the limit block in the absence of external force, that is, when the first screw is installed, when the groove and the cavity are aligned, the insert block is inserted into the groove, thereby limiting the rotation of the first screw. At this time, the nut can be threadedly tightened, so that the first screw can be temporarily limited when the nut is installed, thereby making it more convenient to install the overall lamp.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 12 As shown, the present invention is a fixing structure of a lamp, comprising: A support base 1, on which a lamp body 2 is fixedly mounted, and which is fixedly mounted on a mounting plate 3 via a first screw rod 4, a locking assembly 7 is provided on the support base 1, a nut 402 is threadedly connected to a threaded section of the first screw rod 4, and a groove 401 is provided on the screw head, a through hole 8 is provided in the screw head of the first screw rod 4, and the threaded section is composed of a plurality of circumferentially arranged deformation blocks 802, and a gap 801 is provided between two adjacent deformation blocks 802, and an extrusion cavity 804 is provided in the threaded section of the first screw rod 4, and the extrusion cavity 804 is communicated with the through hole 8; The limit block 5 is fixedly mounted on the support seat 1, and the two limit blocks 5 are symmetrically arranged about the first screw rod 4. A cavity 501 is provided in the limit block 5, and an insert block 6 is slidably mounted in the cavity 501. The insert block 6 is driven to move by the locking assembly 7. When the groove 401 is aligned with the cavity 501, the insert block 6 slides and fits with the groove 401; The extrusion block 803 is slidably installed in the extrusion cavity 804. The extrusion block 803 is driven to move by the driving component 9 arranged on 1. The radii of the extrusion block 803 and the extrusion cavity 804 decrease upward along the axis direction of the first screw 4. The radius of the bottom end of the extrusion block 803 is greater than the radius of the top end of the extrusion cavity 804. When the driving component 9 drives the extrusion block 803 to rise, the extrusion block 803 causes the multiple deformation blocks 802 to expand outward, thereby tightening the nut 402, and at the same time, the driving component 9 drives the plug block 6 to be inserted into the groove 401 through the locking component 7.

[0019] In one case of this embodiment, the support seat 1 and the mounting plate 3 are both provided with reserved holes in advance for allowing the first screw rod 4 to pass through.

[0020] The working principle of the present invention is as follows: first, the support base 1 is attached to the mounting plate 3 so that the reserved holes for the first screw 4 to pass through are aligned. Figure 8 As shown in the figure, the first screw rod 4 is passed through the support seat 1 and the mounting plate 3, and then the nut 402 can be threadedly fastened with the threaded section of the first screw rod 4. At this time, the state inside the first screw rod 4 is as follows: Figure 4 As shown, the extrusion block 803 is located at the bottom of the extrusion cavity 804, and the insert block 6 is located in the cavity 501, and then the extrusion block 803 is driven to rise in the extrusion cavity 804 by the driving component 9. At the same time, the driving component 9 drives the insert block 6 to be inserted into the groove 401 through the locking component 7, so as to fix the screw head of the first screw 4 to prevent the vibration during use from causing the connection between the first screw 4 and the support seat 1 and the first screw 4 and the mounting plate 3 to become loose; The radii of the extrusion block 803 and the extrusion cavity 804 both decrease upward along the axis direction of the through hole 8, that is, they are in the shape of a truncated cone, and the radius of the bottom end of the extrusion block 803 is greater than the radius of the top end of the extrusion cavity 804, which means that the extrusion block 803 will inevitably squeeze the extrusion cavity 804 during its rise, and the extrusion cavity 804 is connected to the notch 801, which means that the diameter of the extrusion cavity 804 can be changed by the elastic deformation of the deformation block 802. Therefore, when the extrusion block 803 rises and squeezes the extrusion cavity 804, the deformation block 802 will expand outward, thereby expanding the diameter of the extrusion cavity 804, and the outer diameter of the deformation block 802 will be increased. Expansion is to tighten the nut 402 so that the nut 402 and the threaded section of the first screw 4 fit more closely, thereby fixing the position of the nut 402, and this connection method is reversible. Different from increasing the connection strength between the nut 402 and the first screw 4 by a locking agent, the extrusion block 803 is driven down by the driving component 9, and the extrusion block 803 loses its extrusion effect, and the deformation block 802 will return to its original position, so that the thread loosening process of the nut 402 can be easily realized without damaging the thread structure of the nut 402 and the first screw 4, thereby achieving the purpose of easy disassembly and reuse.

[0021] like Figure 1-Figure 12 As shown, as a preferred embodiment of the present invention, the locking assembly 7 includes a sliding block 701, an inclined groove 703, a transverse groove 704 and a round rod 705. The sliding block 701 is sleeved on the limit block 5, and the two are slidably connected. The inclined groove 703 is opened on the sliding block 701, which is inclined, and its horizontal height away from the end of the first screw rod 4 is higher than its horizontal height close to the end of the first screw rod 4. The transverse groove 704 is opened on the limit block 5. The round rod 705 is slidably installed in the transverse groove 704, one end of which is slidably installed in the inclined groove 703, and the other end is fixedly connected to the insert block 6. When the driving assembly 9 drives the extrusion block 803 to rise, the driving assembly 9 drives the sliding block 701 to rise.

[0022] In practical application, if Fig. 9 As shown in the figure, at this time, the sliding block 701 is lowered to the limit block 5, and the round rod 705 is located at the end of the transverse groove 704 away from the first screw rod 4. Fig.10 Taking the example shown, when the sliding block 701 rises, that is, when it moves away from the limit block 5, the transverse groove 704 will drive the round rod 705 to move. At this time, the round rod 705 will move in the inclined groove 703, and the movement of the round rod 705 will drive the insert block 6 to move in the cavity 501. When the first screw rod 4 is installed on the support seat 1 and the mounting plate 3, and the groove 401 and the cavity 501 are aligned, the above process will insert the insert block 6 into the groove 401, thereby establishing a rigid connection between the first screw rod 4 and the limit block 5, and completing the position limitation of the first screw rod 4.

[0023] like Figure 1-Figure 12 As shown, as a preferred embodiment of the present invention, the driving assembly 9 includes a second screw 901, a rotating block 902, a through hole 903 and an insertion rod 904, the rotating block 902 is rotatably installed in the through hole 8, the second screw 901 is threadedly connected in the rotating block 902, and its bottom end is fixedly connected to the extrusion block 803, the through hole 903 is opened at the top of the second screw 901, the insertion rod 904 is slidably inserted on the sliding block 701, and it is slidably inserted with the through hole 903.

[0024] In actual application of this embodiment, after the nut 402 is threadedly tightened, the extrusion block 803 is located at the bottom of the extrusion cavity 804, and then the sliding block 701 is moved close to the limit block 5, and then the insertion rod 904 is inserted to establish a rigid connection between the sliding block 701 and the second screw rod 901, and then the rotating block 902 is rotated. Due to the threaded connection between the rotating block 902 and the second screw rod 901, and the second screw rod 901 is connected to the sliding block 701 through the insertion rod 904, the rotation of the second screw rod 901 is restricted. At this time, the rotation of the rotating block 902 drives the second screw rod 901 to rise. On the one hand, it drives the extrusion block 803 to rise and make the deformation block 802 expand outward, thereby tightening the nut 402. On the other hand, it drives the sliding block 701 to rise, thereby inserting the insertion block 6 into the groove 401, so as to simultaneously achieve the fixation of the first screw rod 4 and the nut 402.

[0025] like Figure 3-Figure 12 As shown, as a preferred embodiment of the present invention, the locking assembly 7 also includes a spring 702, the sliding block 701 is connected to the top of the limit block 5 through the spring 702, and the pre-tightening force of the spring 702 makes the sliding block 701 move away from the limit block 5.

[0026] In practical application, if Figure 5 As shown in the example, by setting the spring 702, the sliding block 701 can be located away from the limit block 5 without the action of external force. At this time, the insert block 6 protrudes from the cavity 501. Therefore, when installing the first screw rod 4, when the groove 401 and the cavity 501 are aligned, the insert block 6 is inserted in the groove 401, thereby limiting the rotation of the first screw rod 4. At this time, the threaded tightening of the nut 402 can be carried out. In this way, the first screw rod 4 can be temporarily limited when the nut 402 is installed, thereby making it more convenient to install the overall lamp.

[0027] like Figure 5-Figure 6 As shown, as a preferred embodiment of the present invention, the end of the insert block 6 close to the first screw rod 4 is provided with an angled corner 601 , and the angled corner 601 is slidably matched with the bottom edge of the screw head of the first screw rod 4 .

[0028] In actual application of this embodiment, through the design of the bevel 601, when installing the first screw rod 4, the first screw rod 4 is directly installed along the limit block 5. At the beginning, the bottom edge of the screw head of the first screw rod 4 will abut against the bevel 601. As the first screw rod 4 is pressed downward, the bottom edge of the screw head of the first screw rod 4 will slide downward on the bevel 601, gradually squeezing the bevel 601 into the cavity 501, thereby facilitating the installation of the first screw rod 4.

[0029] like Figure 4-Figure 11As shown, as a preferred embodiment of the present invention, a grooved block 11 is fixedly installed on the sliding block 701, and a protrusion 10 is fixedly installed on the insertion rod 904. When the insertion rod 904 passes through the sliding block 701 and is inserted into the through hole 903, the protrusion 10 and the grooved block 11 are rotatably engaged.

[0030] In practical application, if Fig. 9 As shown, the insertion rod 904 is gradually inserted into the through hole 903, and then Fig.10 As shown, when the insertion rod 904 is fully inserted into the through hole 903, a rigid connection is established between the second screw 901 and the sliding block 701. The insertion rod 904 is then manually rotated so that the protrusion 10 is rotated and snapped into the groove of the grooved block 11, thereby ensuring that when the mounting plate 3 is vibrated, the insertion rod 904 will not be directly moved out of the through hole 903, thereby avoiding the vibration causing the rigid connection between the sliding block 701 and the second screw 901 to loosen, thereby further improving the limiting effect on the first screw 4.

[0031] like Figure 2-Figure 12 As shown, as a preferred embodiment of the present invention, a locking washer 12 is sleeved on the threaded section of the first screw 4. When the support seat 1 is fixedly mounted on the mounting plate 3 through the first screw 4, the locking washer 12 is located between the nut 402 and the mounting plate 3.

[0032] In actual application of this embodiment, when the nut 402 is tightened, the locking washer 12 is squeezed by the nut 402 and deformed, generating elastic force, so that the nut 402 is subjected to greater pressure and is not easy to loosen. This increased tightening force cooperates with the tensioning force of the nut 402 exerted by the outward expansion of the deformation block 802, making the connection between the first screw 4 and the nut 402 more stable.

[0033] like Figure 11-Figure 12 As shown, as a preferred embodiment of the present invention, the limit block 5 is located on one side of the first screw rod 4, and the limit block 5 forms an angle of forty-five degrees with the axis of the first screw rod 4.

[0034] In practical application, if Fig.12 As shown in the example, by limiting the position of the limit block 5 at a forty-five degree direction of the first screw 4, it is farther away from the edge of the support seat 1, so that the width of the support seat 1 can be reduced, and the limit block 5 is farther away from the edge of the support seat 1, and is not easy to deform or wear when it is vibrated.

[0035] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
