Description

Technical Field

[0001] The invention relates to the technical field of lamp bases, in particular to a lamp protection base with an anti-tilt function. Background Art

[0002] At present, with the discovery of electricity, electric lights are used more and more widely in people's daily lives. Lamps are tools that people use electric lights for lighting, especially at night, which can bring people light like daylight.

[0003] When fixing a wall lamp on an exterior wall, a hole is usually drilled on the wall first, and the depth of the hole should exceed the depth of the expansion tube so that the expansion tube can be fully embedded in the hole when the nut is tightened. Secondly, during the drilling process, the hole diameter of the drill bit is often larger than the size of the expansion tube, which makes the hole diameter larger. In addition, when drilling, the drill bit is moved in the hole by reciprocating to increase the depth of the hole, which will cause the hole diameter on the wall to become larger accordingly. In order to prevent the conical bolt from being unable to be tightened after the hole diameter increases, a wooden block is embedded around the expansion tube, and the expansion tube is supported by the wooden block, so that the bottom plate of the wall lamp can be fixed when the nut is tightened.

[0004] However, since the wall lamp is fixed outdoors and is eroded by rain for a long time, the wood blocks are prone to rot, mold, etc., causing the wood blocks to lose the restriction on the expansion tube. At this time, the expansion tube is loose and under the action of the gravity of the wall lamp, the base plate and the wall lamp become tilted, resulting in incorrect light projection direction, affecting the comfort and visual effect of the living environment.

A counterweight block is slidably connected inside the oblique branch pipe. The mass of the counterweight block is less than the mass of the ejection block, and the top of the counterweight block is close to the end of the oblique branch pipe.

[0013] As a further improvement of the technical solution, the upper surface of the ejection block is rotatably connected to an arc-shaped lever, and a limit block provided on the right side of the arc-shaped lever is fixedly connected to the ejection block.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] Example like Figure 1-Figure 4As shown, a protective base for a lamp with anti-tilt is provided, including a bottom plate 100 connected to the wall lamp, the bottom plate 100 is fixed to the wall by two upper and lower conical screws, a U-shaped tube 120 is arranged on the front side of the bottom plate 100 (the back side is the side close to the wall), the U-shaped tube 120 is composed of two upper straight tubes and a lower curved tube, an impact mechanism is arranged inside the left upper straight tube, and a power unit 200 and a telescopic airbag 140 are arranged inside the right upper straight tube, the power unit 200 uses wind power as a driving force for The telescopic airbag 140 is squeezed, and the gas released from the telescopic airbag 140 pushes the impact mechanism to move. The impact mechanism includes an ejection block 150 and a counterweight block 160. A limit body 170 is provided above the counterweight block 160. The counterweight block 160 is used to impact the limit body 170, and cooperate with the ejection block 150 to move the gasket gear 110 provided on the outer ring of the conical screw to realize the rotation of the gasket gear 110, thereby tightening the loose base plate 100 again to prevent the base plate 100 from tilting.

[0024] It should be noted that: Figure 3 For example, the position where the telescopic airbag 140 is located is the right upper straight tube, and vice versa is the left upper straight tube, hereinafter referred to as the left upper straight tube and the right upper straight tube.

[0025] First, when the wall lamp is tilted (i.e. the bottom plate 100 is tilted), the two upper and lower conical screws are loosened. Under the effect of the gravity of the wall lamp, the bottom of the bottom plate 100 is in contact with the wall, while the upper part is separated from the wall. For details, please refer to Figure 2 shown.

[0026] The washer gear 110 not only serves as a washer, but also can fix the base plate 100 by rotating.

[0027] Therefore, when the gasket gear 110 is tightened, the power unit 200 is used to squeeze the telescopic airbag 140, and the gas squeezed out of the telescopic airbag 140 pushes the ejection block 150 and the counterweight block 160 to move, and under the action of the ejection block 150 and the counterweight block 160, the counterweight block 160 knocks the limiter 170 to make the gasket gear 110 drive the expansion tube to move outward, so that the expansion tube is tightly against the wall surface, preventing the conical screw from slipping when the gasket gear 110 rotates, and then cooperates with the ejection block 150 to drive the gasket gear 110 to rotate, thereby fixing the base plate 100.

[0028] Therefore, based on the above structure, Figure 3The structure of the power unit 200 is further disclosed. The power unit 200 includes an auxiliary block 230, which is slidably connected to the upper straight tube on the right side. The auxiliary block 230 is threadedly matched with the reciprocating screw 220. The reciprocating screw 220 is located on the upper straight tube on the right side. The connecting rod 211 coaxially connected to the top of the reciprocating screw 220 is rotatably connected to the upper straight tube on the right side. The top of the connecting rod 211 is symmetrically provided with a power wind cup 210. On the other hand, the telescopic airbag 140 is located at the bottom of the auxiliary block 230. The telescopic airbag 140 and the reciprocating screw 220 are supported by a support plate fixed inside the upper straight tube on the right side, and air holes are opened on the support plate. In this way, the power wind cup 210 is driven to rotate by the external airflow, and the connecting rod 211 drives the reciprocating screw 220 to rotate. Because the reciprocating screw 220 is threadedly matched with the auxiliary block 230, the rotation of the reciprocating screw 220 causes the auxiliary block 230 to move downward to squeeze the telescopic airbag 140. As the telescopic airbag 140 is continuously squeezed, the gas stored in the telescopic airbag 140 is discharged from the air holes, so that force can be accumulated for pushing the ejection block 150 and the counterweight block 160 later.

[0029] Secondly, considering that the telescopic airbag 140 will expand outward during the squeezing process, causing friction between it and the reciprocating screw 220, a partition is arranged between the telescopic airbag 140 and the reciprocating screw 220, and the partition is slidably connected to the auxiliary block 230, so that the telescopic airbag 140 and the reciprocating screw 220 are separated by the partition, thereby protecting the telescopic airbag 140.

[0030] Then, the gas discharged from the telescopic airbag 140 is stored in the lower curved tube of the U-shaped tube 120, as shown below: a horizontal plate is provided at the end of the lower curved tube, a pressure relief valve is provided on the horizontal plate, an air inlet hole 121 is provided in the middle of the lower curved tube, and a one-way valve is provided in the air inlet hole 121. When the gas is stored in the lower curved tube of the U-shaped tube 120, during this process, the one-way valve in the air inlet hole 121 is closed, the pressure relief valve on the horizontal plate is closed, and when the gas in the lower curved tube breaks through the pressure relief valve, the compressed gas is discharged from the upper straight tube on the left side to push the ejection block 150 to move. On the contrary, when the telescopic airbag 140 inhales gas, the one-way valve in the air inlet hole 121 is opened, the pressure relief valve on the horizontal plate is closed, and the telescopic airbag 140 inhales air from the outside to prepare for the next power storage.

[0031] Further, combined with Figure 4As shown, after the gas breaks through the pressure relief valve, the gas instantly pushes the ejector block 150 to move upward, and the ejector block 150 is slidably connected to the upper straight pipe on the left side, and the upper part of the upper straight pipe on the left side is connected to the oblique branch pipe 130, and the counterweight block 160 is slidably connected inside the oblique branch pipe 130. In this way, when the ejector block 150 moves upward to exceed the connection between the upper straight pipe on the left side and the oblique branch pipe 130, at this time, a small part of the gas pushes the ejector block 150 so that the ejector block 150 continues to move upward under the action of inertia, while most of the gas enters the oblique branch pipe 130 to push the counterweight block 160 to move upward.

[0032] Because the mass of the counterweight block 160 is smaller than that of the ejector block 150, the top of the counterweight block 160 is close to the end of the oblique branch pipe 130, and the washer gear 110 is threadedly connected to the conical screw. In this way, when the ejector block 150 moves upward from the connection between the oblique branch pipe 130 and the left upper straight pipe, and before the ejector block 150 reaches the top, the gas flowing through the oblique branch pipe 130 has already pushed the counterweight block 160 to hit the limiter 170, that is, the counterweight block 160 hits the limiter 170 first, and then the ejector block 150 realizes the toggle of the washer gear 110.

[0033] Then combine Figure 6 As shown, the impact of the counterweight 160 on the limiter 170 is first described, wherein the two ends of the counterweight 160 are fixedly connected to the limiter rods 161, the limiter rods 161 are slidably connected to the oblique branch pipe 130, and the limiter 170 is provided with a blocking block 171 at the end of the oblique branch pipe 130. Figure 6 Based on and combined with Figure 7 and Figure 8 As shown, the two sides of the limiting body 170 are provided with slide rails 180, the slide rails 180 are fixedly connected to the bottom plate 100, and the sliding rails 180 and the limiting body 170 are both provided with saw teeth 181 at the joints, and the saw teeth 181 on both sides are arranged in opposite directions. In this way, when the gas pushes the counterweight block 160 to move upward instantly, the counterweight block 160 hits the blocking block 171, so that the limiting body 170 slides upward, that is, the saw teeth 181 on both sides are in sliding connection at this time, so as to realize the upward movement of the limiting body 170, and the spacer gear 110 is squeezed by the upward movement of the limiting body 170.

[0034] Next, because the limiting body 170 is provided with an inclined surface near the gasket gear 110, during the upward movement of the limiting body 170, the inclined surface squeezes the gasket gear 110, so that the gasket gear 110 drives the conical screw to move outward. At this time, the expansion tube is also driven by the conical screw to tightly abut against the wall in the hole, preventing the conical screw from slipping when the gasket gear 110 rotates, and can also make the base plate 100 tilt toward the wall with the gasket gear 110 as the fulcrum, thereby reducing the inclination angle of the base plate 100 and adjusting the illumination direction of the wall lamp.

[0035] When the limiter 170 stops moving upward, the serrations 181 on the slide rail 180 and the serrations 181 on the limiter 170 are interlaced with each other, that is, the slide rail 180 limits the downward movement of the limiter 170, thereby maintaining the state in which the limiter 170 squeezes the gasket gear 110.

[0036] In addition, when the counterweight block 160 is exposed from the end of the inclined branch pipe 130, the limit rods 161 on both sides are still located in the inclined branch pipe 130, and the gas is discharged to the outside from both sides of the counterweight block 160. When the thrust of the gas on the counterweight block 160 disappears, the counterweight block 160 slides downward into the inclined branch pipe 130 under the action of gravity.

[0037] Combine the following Figure 5 The moving process of the ejection block 150 is described as follows. The upper surface of the ejection block 150 is rotatably connected with an arc-shaped lever 151. The limit block 153 provided on the right side of the arc-shaped lever 151 is fixedly connected to the ejection block 150. The arc-shaped lever 151 is used to limit the rotation of the arc-shaped lever 151. The arc-shaped lever 151 is used to drive the gasket gear 110 to rotate during the upward movement. Figure 5 Based on and combined with Figure 6 and Figure 8 As shown, during the upward movement of the limit body 170, the arc-shaped lever 151 abuts against the tooth groove of the outer ring of the gasket gear 110, so that the gasket gear 110 rotates to squeeze the inclined surface of the limit body 170, and the conical screw is pulled outward at this time. The expansion tube is tightly abutted against the hole under the action of the conical screw, so that the base plate 100 gradually returns to a state of being in contact with the wall, thereby preventing the base plate 100 from tilting.

[0038] Furthermore, in order to prevent the ejection block 150 from detaching from the left upper straight tube, protrusions 122 are provided on both sides of the end of the left upper straight tube, and limiting grooves 154 are provided on both sides of the ejection block 150 corresponding to the protrusions 122 in the vertical direction. The protrusions 122 are used to limit the upward movement of the ejection block 150.

[0039] When the ejection block 150 moves downward, the return spring 152 is arranged on the opposite side of the limit block 153, and the two ends of the return spring 152 are respectively connected to the arc lever 151 and the ejection block 150. When the arc lever 151 moves downward, the return spring 152 limits the arc lever 151 to prevent the arc lever 151 from contacting the tooth groove and rotating in the opposite direction, thereby keeping the arc lever 151 close to the limit block 153.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
