Description

Technical Field

[0001] The invention relates to the field of lighting, and in particular to a lampshade fixing method. Background Art

[0002] For the floodlights commonly used on the market, the cover between the lampshade and the lamp body is basically fixed by screws or spring clips to tighten the glass pressure ring or glass, and the glass is pressed and deformed by the silicone ring to achieve a waterproof effect. The solution of tightening the glass pressure ring or glass by screws or spring clips, and the glass is pressed and deformed by the waterproof silicone ring to achieve a waterproof effect, has the following disadvantages: First, using screws or spring clips to tighten the lampshade and the lamp body requires punching holes in the lampshade. If the holes are loose, it is easy to cause the cover between the lampshade and the lamp body to be loose, and the holes often cause damage to the lampshade; second, the screws or spring clips are easy to be disassembled, resulting in the inability to prevent disassembly. It is easy to remove them with conventional screwdrivers or wrenches on the market, and the anti-theft effect is poor. Third, the seal between the lampshade and the lamp body is not strong, and water is easy to enter. Fourth, screws are punched on the lampshade or the lamp body, and the screw heads are exposed, affecting the overall appearance of the product. Summary of the invention

[0003] The object of the present invention is to provide a lamp in order to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A lamp comprises a lamp body and a lampshade, and also comprises a press buckle. Under the constraint of the press buckle, the lampshade can stably cover the opening of the lamp cavity of the lamp body. When the constraint applied by the press buckle is released, the lampshade can be detached from the lamp body.

[0006] In this way, a detachable cover can be formed between the lamp body and the lampshade, which is convenient for replacement and maintenance of the lampshade and the lamp body after removal, thereby improving the utilization rate of the lampshade and the lamp body, and there is no need to drill holes to damage the lampshade and the lamp body.

[0007] Specifically, the pressing buckle includes a pressing block, and when the constraint is applied, the pressing block presses the joint between the lampshade and the lamp body. This can prevent the lampshade from loosening from the lamp body and improve the stability of the cover between the lampshade and the lamp body. The shape of the outer periphery of the lampshade is consistent with the shape of the inner wall of the lamp cavity opening.

[0008] The lamp also includes: a limit pin, and a limit hole is arranged on the buckle. When the limit pin is inserted into the limit hole, the constraint is applied, and when the limit pin is separated from the limit hole, the constraint is released.

[0009] When the limiting hole is worn and deformed, the limiting pin is replaced to adapt to the worn and deformed limiting hole, thereby improving the utilization rate of the buckle.

[0010] When the limiting pin is inserted into the limiting hole, the limiting pin and the limiting hole are loosely matched.

[0011] On the one hand, the wear between the limiting pin and the limiting hole can be reduced; on the other hand, it is easy to take out and insert the limiting pin, thereby improving the working efficiency of covering and separating between the lamp body and the lampshade.

[0012] A guide groove and a guide hole are provided on the lamp body; the buckle includes a guide portion, and when the guide portion is inserted into the guide groove, the limiting hole is aligned with the guide hole, and the limiting pin can pass through the guide hole and be inserted into the limiting hole.

[0013] On the one hand, the cooperation between the guide part and the guide groove facilitates the positioning of the buckle, thereby improving the efficiency of using the buckle to constrain the covering of the lampshade and the lamp body. On the other hand, the buckle is restricted in the guide groove to prevent the buckle from shaking, thereby improving the stability of the covering between the lampshade and the lamp body.

[0014] The limiting pin comprises a locking protrusion, and when the limiting pin is inserted into the limiting hole, the locking protrusion is locked in a side of the guide groove close to the guide hole.

[0015] The locking projection is locked on the side of the guide groove close to the guide hole so that the limit pin cannot be inserted further. On the one hand, the insertion depth of the limit pin into the lamp body can be located, thereby improving the efficiency of positioning the limit pin; on the other hand, the non-insertion end of the limit pin can be prevented from completely passing over the wall of the lamp body at the guide groove, thereby preventing the limit pin from being stuck on the side of the wall close to the guide groove and making it difficult to remove the limit pin.

[0016] Specifically, the locking protrusion surrounds the positioning pin for one circle, or the locking protrusion may not surround the positioning pin for one circle, but for half a circle, or more than half a circle and less than one circle, or less than half a circle.

[0017] When the limiting pin is inserted into the limiting hole, the non-insertion end of the limiting pin sinks into the guide hole.

[0018] On the one hand, it prevents the limit pin from being exposed outside the lamp body and causing harm to the staff; on the other hand, it prevents the limit pin from being exposed outside the lamp body and being loosened by collision and affecting the overall neatness of the product.

[0019] The guide groove is provided with a protrusion, and when the limiting pin is inserted beyond the limiting hole, the protrusion fits with the side of the limiting pin close to the lampshade.

[0020] This can prevent the limit pin from tilting toward the side close to the lampshade, so that the force of the limit pin on the buckle is stable, thereby ensuring the restraining force of the buckle and improving the stability of the covering between the lampshade and the lamp body.

[0021] Specifically, the protrusion is a step on the guide groove, or the protrusion is a rectangular block or a trapezoidal block on the guide groove, or the protrusion is a block with an arc surface on the guide groove.

[0022] The limiting hole is provided with a gear gap, and the limiting pin is provided with a protruding gear. When and only when the protruding gear is aligned with the gear gap, the limiting pin can be inserted into or out of the limiting hole. When the limiting pin is inserted into the limiting hole, the protruding gear is located in the gear gap, and the protruding gear does not cross the gear gap.

[0023] The alignment of the protruding gear position with the gear position notch can prevent the locating pin from rotating in the radial direction, thereby preventing the locating pin from loosening in the radial direction, improving the stability of the locating pin in the limiting hole, improving the stability of the fit between the locating pin and the buckle, and improving the stability of the cover between the lampshade and the lamp body.

[0024] Preferably, a gear notch is provided on the limiting hole, and a protruding gear is provided on the limiting pin. The limiting pin can be inserted into or disengaged from the limiting hole when and only when the protruding gear is aligned with the gear notch. When the protruding gear passes over the gear notch, the limiting pin is rotated at a certain angle so that the protruding gear is stuck on the side of the buckle away from the guide hole.

[0025] In this way, after the pressing buckle constrains the lampshade and the lamp body to cover, the protruding gear is stuck around the limiting hole of the pressing buckle, which can prevent the limiting pin from falling off from the limiting hole, thereby enhancing the stability of the covering of the lampshade and the lamp body.

[0026] Preferably, the lamp further comprises an elastomer, and when the elastomer is located between the lampshade and the lamp body, the elasticity of the elastomer can press the lampshade and the buckle tightly, and can also press the buckle and the limit pin tightly.

[0027] This can prevent the lampshade and the buckle from loosening, which would cause an unstable cover between the lampshade and the lamp body.

[0028] Preferably, the elastomer is silicone.

[0029] Preferably, the elastomer is a circle, and a ring groove is provided on the lamp body, the ring groove surrounds the lamp cavity opening, the shape of the elastomer is adapted to the ring groove, the elastomer can be installed in the ring groove, so as to position the elastomer, and the outer edge of the lampshade is consistent with the shape of the lamp cavity opening. When the lampshade is covered over the ring groove with the elastomer installed, the elastomer seals the joint between the lampshade and the lamp body to prevent water from entering the joint between the lampshade and the lamp body.

[0030] Preferably, the axial distance between the protruding gear position and the locking protrusion on the limit pin is equal to the thickness of the buckle around the limit hole. When the protruding gear position passes over the gear position gap, the limit pin is rotated at a certain angle, and the protruding gear position is stuck on the side of the buckle away from the guide hole, while at the same time, the locking protrusion is just stuck on the side of the buckle close to the guide hole, thereby further preventing the buckle from shaking and improving the stability of the cover between the lampshade and the lamp body.

[0031] Preferably, the number of buckles is more than three, and the number of buckles, the number of guide grooves, the number of guide holes and the number of limit pins are the same. The buckles, guide grooves, guide holes and limit pins are evenly distributed around the periphery of the lampshade, thereby improving the stability of the cover between the lampshade and the lamp body.

[0032] A covering method, using the lamp described in the previous embodiment, the steps are as follows:

[0033] 1) Place the elastic body between the lampshade and the lamp body;

[0034] 2) The lampshade is pressed by a pneumatic jig, and the lampshade is pressed on the elastic body, causing the elastic body to deform under pressure;

[0035] 3) inserting the pressing buckle and the limiting pin; the limiting pin, the pressing buckle is provided with a limiting hole, when the limiting pin is inserted into the limiting hole, the pressing buckle can make the lampshade stably cover the open part of the lamp cavity of the lamp body;

[0036] 4) After confirming that the buckle and limit pin are inserted, open the pneumatic fixture;

[0037] 5) The elastic body rebounds and squeezes the lampshade and the buckle tightly, and at the same time squeezes the contact between the limit hole of the buckle and the limit pin, and squeezes the limit pin and the guide groove tightly, so as to achieve the effect of stably covering the lampshade and the lamp body.

[0038] This ensures that the lampshade and the lamp body are covered stably without shaking.

[0039] In step 1), the elastomer is a circle, and a ring groove is provided on the lamp body. The ring groove surrounds the opening of the lamp cavity. The shape of the elastomer is adapted to that of the ring groove. The elastomer can be installed in the ring groove to position the elastomer. The outer edge of the lampshade is consistent with the shape of the opening of the lamp cavity. The lampshade is covered on top of the ring groove with the elastomer installed, so that after step 5), the elastomer can seal the joint between the lampshade and the lamp body to prevent water from entering the joint between the lampshade and the lamp body.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1) The pressing buckle restraint method can form a detachable cover between the lamp body and the lampshade, which is convenient for replacing and repairing the lampshade and the lamp body after disassembly, thereby improving the utilization rate of the lampshade and the lamp body, and there is no need to drill holes to damage the lampshade and the lamp body.

[0042] 2) By using the matching method of the limit hole and the limit pin of the buckle, when the limit hole is worn and deformed, the limit pin can be replaced to adapt to the worn and deformed limit hole, thereby improving the utilization rate of the buckle. There is no need to punch holes on the lampshade, the lampshade will not be damaged, and there will be no looseness at the punching point.

[0043] 3) The cooperation between the guide part, the guide groove, the limiting hole and the guide hole is beneficial to the cooperation between the guide part and the guide groove, which facilitates the positioning of the buckle and improves the efficiency of using the buckle to constrain the covering of the lampshade and the lamp body. The buckle is restricted in the guide groove to prevent the buckle from shaking, thereby improving the stability of the covering between the lampshade and the lamp body.

[0044] 4) The guide groove is provided with a protrusion. When the limit pin is inserted beyond the limit hole, the protrusion fits with the side of the limit pin close to the lampshade. This can prevent the limit pin from tilting toward the side close to the lampshade, making the force of the limit pin on the buckle stable, thereby ensuring the restraining force of the buckle and improving the stability of the cover between the lampshade and the lamp body.

[0045] 5) The covering method utilizes an air pressure fixture, which can ensure that the lampshade and the lamp body are covered stably without shaking. The elastic body seals the joint between the lampshade and the lamp body to prevent water from entering the joint between the lampshade and the lamp body, and the lampshade is not easily stolen, thereby playing an anti-theft role.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0063] The present invention will be further described below in conjunction with the accompanying drawings:

[0064] The above shows and describes a lamp of the present invention, including a lamp body 6 and a lampshade 2, and also includes: a buckle 1, under the constraint of the buckle 1, the lampshade 2 can stably cover the open part of the lamp cavity of the lamp body 6, when the constraint imposed by the buckle 1 is released, the lampshade 2 can be detached from the lamp body 6.

[0065] In this way, a detachable cover can be formed between the lamp body 6 and the lampshade 2 , which facilitates replacement and maintenance of the lampshade 2 and the lamp body 6 after they are disassembled, thereby improving the utilization rate of the lampshade 2 and the lamp body 6 .

[0066] Specifically, the pressing buckle 1 includes a pressing block, and when the constraint is applied, the pressing block presses the joint between the lampshade 2 and the lamp body 6. This can prevent the lampshade 2 from loosening from the lamp body 6, and improve the stability of the covering between the lampshade 2 and the lamp body 6. The shape of the outer periphery of the lampshade 2 is consistent with the shape of the inner wall of the lamp cavity opening.

[0067] The lamp also includes: a limit pin 7, and a limit hole 9 is arranged on the buckle 1. When the limit pin 7 is inserted into the limit hole 9, the constraint is applied, and when the limit pin 7 is separated from the limit hole 9, the constraint is released.

[0068] When the limiting hole 9 is worn and deformed, the limiting pin 7 is replaced to adapt to the worn and deformed limiting hole 9, thereby improving the utilization rate of the buckle 1. It is not necessary to punch holes in the lampshade 2, the lampshade will not be damaged, and there will be no looseness at the punching position.

[0069] When the limiting pin 7 is inserted into the limiting hole 9 , the limiting pin 7 and the limiting hole 9 are clearance-matched.

[0070] On the one hand, the wear between the limiting pin 7 and the limiting hole 9 can be reduced; on the other hand, it is convenient to take out and insert the limiting pin 7, thereby improving the working efficiency of covering and separating between the lamp body 6 and the lampshade 2.

[0071] A guide groove 15 and a guide hole 8 are provided on the lamp body 6; the buckle 1 includes a guide portion, and when the guide portion is inserted into the guide groove 15, the limiting hole 9 is aligned with the guide hole 8, and the limiting pin 7 can pass through the guide hole 8 and be inserted into the limiting hole 9.

[0072] On the one hand, the cooperation between the guide portion and the guide groove 15 facilitates the positioning of the buckle 1, thereby improving the efficiency of using the buckle 1 to constrain the covering of the lampshade 2 and the lamp body 6. On the other hand, the buckle 1 is restricted in the guide groove 15 to prevent the buckle 1 from shaking, thereby improving the stability of the covering between the lampshade 2 and the lamp body 6.

[0073] The limiting pin 7 includes a locking protrusion 11 . When the limiting pin 7 is inserted into the limiting hole 9 , the locking protrusion 11 is locked in the guide groove 15 at a side close to the guide hole 8 .

[0074] The locking projection 11 is locked on the side of the guide groove 15 close to the guide hole 8 so that the stop pin 7 cannot be further inserted. On the one hand, the insertion depth of the stop pin 7 into the lamp body 6 can be located, thereby improving the efficiency of positioning the stop pin 7; on the other hand, the non-insertion end 10 of the stop pin 7 can be prevented from completely passing over the wall of the lamp body 6 at the guide groove 15, thereby preventing the stop pin 7 from being stuck on the side of the wall close to the guide groove 15 and making it difficult to remove the stop pin 7.

[0075] Specifically, the positioning protrusion 11 surrounds the positioning pin (eg Figure 3-7 ), the positioning protrusion 11 may not surround the positioning pin for a circle, but for half a circle, or more than half a circle and less than a circle, or less than half a circle.

[0076] The guide groove 15 is provided with a protrusion 14 . When the limiting pin 7 is inserted beyond the limiting hole 9 , the protrusion 14 fits with the side of the limiting pin 7 close to the lampshade 2 .

[0077] When the limiting pin 7 is inserted into the limiting hole 9 , the non-insertion end 10 of the limiting pin 7 sinks into the guide hole 8 .

[0078] On the one hand, it prevents the limit pin 7 from being exposed outside the lamp body 6 and causing harm to the staff; on the other hand, it prevents the limit pin 7 from being exposed outside the lamp body 6 and being loosened by collision and affecting the overall appearance of the product.

[0079] This can prevent the limit pin 7 from tilting toward the side close to the lampshade 2, so that the force of the limit pin 7 on the buckle 1 is stable, thereby ensuring the restraining force of the buckle 1 and improving the stability of the covering between the lampshade 2 and the lamp body 6.

[0080] Specifically, the protrusion 14 is a step on the guide groove 15 (such as Figure 8 and Fig. 9 ), or the protrusion 14 is a rectangular block on the guide groove 15, a trapezoidal block (such as Fig.10 and Fig.11 ), or the protrusion 14 is a block with an arc surface on the guide groove 15 (such as Fig.12 and Fig.13 ).

[0081] The limiting hole 9 is provided with a gear gap 13, and the limiting pin 7 is provided with a protruding gear position 12. The limiting pin 7 can be inserted into or out of the limiting hole 9 only when the protruding gear position 12 is aligned with the gear gap 13. When the limiting pin 7 is inserted into the limiting hole 9, the protruding gear position 12 is located in the gear gap 13, and the protruding gear position 12 does not cross the gear gap 13.

[0082] The alignment of the protruding gear position 12 with the gear position notch 13 can prevent the locating pin from rotating in the radial direction, thereby preventing the locating pin from loosening in the radial direction, improving the stability of the locating pin in the limiting hole 9, improving the stability of the fit between the locating pin and the buckle 1, and improving the stability of the cover between the lampshade 2 and the lamp body 6.

[0083] In some embodiments, a gear gap 13 is provided on the limiting hole 9, and a protruding gear position 12 is provided on the limiting pin 7. When and only when the protruding gear position 12 is aligned with the gear gap 13, the limiting pin 7 can be inserted into or out of the limiting hole 9. When the protruding gear position 12 passes over the gear gap 13, the limiting pin 7 is rotated at a certain angle so that the protruding gear position 12 can be stuck on the side of the buckle 1 away from the guide hole 8.

[0084] In this way, after the buckle 1 constrains the lampshade 2 and the lamp body 6 to cover, the protruding gear 12 can be stuck around the limiting hole 9 of the buckle 1 to prevent the limiting pin 7 from falling off from the limiting hole 9, thereby enhancing the stability of the covering of the lampshade 2 and the lamp body 6.

[0085] In some embodiments, the lamp further includes an elastomer 3. When the elastomer 3 is located between the lampshade 2 and the lamp body 6, the elasticity of the elastomer 3 can press the lampshade 2 and the buckle 1 tightly, and can also press the buckle 1 and the limiting pin 7 tightly.

[0086] This can prevent the lampshade 2 and the buckle 1 from loosening, thereby preventing the lampshade 2 and the lamp body 6 from being unstable.

[0087] Preferably, the elastomer 3 is silicone.

[0088] In some embodiments, the elastomer 3 is a circle, and a ring groove is provided on the lamp body 6, and the ring groove surrounds the opening of the lamp cavity. The shape of the elastomer 3 is adapted to the shape of the ring groove, and the elastomer 3 can be installed in the ring groove to position the elastomer 3. The outer edge of the lampshade 2 is consistent with the shape of the opening of the lamp cavity. When the lampshade 2 is covered over the ring groove where the elastomer 3 is installed, the elastomer 3 seals the joint between the lampshade 2 and the lamp body 6 to prevent water from entering the joint between the lampshade 2 and the lamp body 6.

[0089] In some embodiments, the axial distance between the protruding gear position 12 and the locking protrusion 11 on the limit pin 7 is equal to the thickness of the buckle 1 around the limit hole 9. When the protruding gear position 12 passes over the gear notch 13, the limit pin 7 is rotated at a certain angle, and the protruding gear position 12 is locked on the side of the buckle 1 away from the guide hole 8, while the locking protrusion 11 is just locked on the side of the buckle 1 close to the guide hole 8, thereby further preventing the buckle 1 from shaking and improving the stability of the cover between the lampshade 2 and the lamp body 6.

[0090] In some embodiments, the number of buckles 1 is more than three, the number of buckles 1, the number of guide grooves 15, the number of guide holes 8 and the number of limit pins 7 are the same, and the buckles 1, guide grooves 15, guide holes 8 and limit pins 7 are evenly distributed around the periphery of the lampshade 2, thereby improving the stability of the cover between the lampshade 2 and the lamp body 6.

[0091] A covering method, using the lamps described in the above embodiments, comprises the following steps:

[0092] 1) Place the elastic body 3 between the lampshade 2 and the lamp body 6;

[0093] 2) The lampshade 2 is pressed by a pneumatic jig, and the lampshade 2 is pressed on the elastic body 3, and the elastic body 3 is deformed by the pressure;

[0095] 4) After confirming that the buckle 1 and the limit pin 7 are inserted, open the pneumatic fixture;

[0096] 5) The elastic body 3 rebounds and squeezes the lampshade 2 and the buckle 1 tightly, and at the same time squeezes the contact between the limiting hole 9 of the buckle 1 and the limiting pin 7, and squeezes the limiting pin 7 and the guide groove 15 tightly, so as to achieve the effect of stably covering the lampshade 2 and the lamp body 6.

[0097] In this way, the lampshade and the lamp body are stably covered and do not shake, and the lampshade is not easily stolen using common tools such as a screwdriver or a wrench, thus playing an anti-theft role.

[0098] Specifically, the pneumatic fixture is a cylinder.
