Emergency power supply device

Abstract

The utility model relates to an emergency power supply device. A sliding block is accommodated through a through hole of a base. Actually, the through hole penetrates through the opposite side walls of the base between the top surface and the bottom surface of the base. The first sliding rod serves as a guide rod of the sliding block, and when the second sliding rod abuts against the sliding block and gives thrust to the sliding block, the first sliding rod guides the sliding block to be close to the top face of the base. The process that the sliding block is close to the top face of the base is the process that the emergency power supply device is meshed with the power supply busbar. The hinge groove is rotationally connected with a connecting block through a connecting rod, and the connecting block can be fixedly connected with the conductive tube and guide current. In fact, the connecting block is rotatably connected with the base, so that the emergency power supply device can adapt to power supply busbars with different specifications and different working states. The emergency power supply device overcomes the defect that a traditional emergency power supply device cannot cope with power supply busbars of different specifications and different working states.

Description

[0062] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0063] The present application provides an emergency power supply device.

[0064] like Figure 1 As shown, in one embodiment of the present application, an emergency power supply device includes a base 100 , a sliding device 200 , a conductive rod 300 and a protective cover 400 .

[0065] The base 100 is set to be C-shaped, and the base 100 is provided with a hinge groove 110, a through hole 120, a first guide hole 130 and a second guide hole 140. The base 100 includes a first plate body 101, a second plate body 102 and a connecting plate body 103, the first plate body 101 and the second plate body 102 are parallel to each other, the connecting plate body 103 is perpendicular to the first plate body 101, and the connecting plate body 103 is also perpendicular to the second plate body 102, and the connecting plate body 103 is connected between the first plate body 101 and the second plate body 102 so that the first plate body 101, the second plate body 102 and the connecting plate body 103 are sequentially connected to form a C-shaped structure. The first guide hole 130 is provided on the top surface of the first plate body 101 base 100, and the axis of the first guide hole 130 along the axial center is perpendicular to the top surface of the first plate body 101 base 100. The second guide hole 140 is provided on the second plate body 102, and the axis of the second guide hole 140 along the axial center is perpendicular to the top and bottom surfaces of the second plate body 102 base 100. The axis of the first guide hole 130 along the axial center is parallel to the axis of the second guide hole along the axial center. The through hole 120 is provided on the connecting plate body 103, and the extension direction of the through hole 120 along the center line is perpendicular to the axis of the second guide hole 140 along the axial center. The hinge groove 110 is provided near the second guide hole 140, and the extension direction of the hinge groove 110 is perpendicular to the extension direction of the through hole 120.

[0066] The sliding device 200 includes a slider 210, a first slider 220 and a second slider 230. One end of the first slider 220 is provided with a thread. The threaded portion of the first slider 220 is threadedly connected to the first guide hole 130. The smooth portion of the first slider 220 extends into the through hole 120. The second slider 230 is threadedly connected to the second guide hole 140. The slider 210 is arranged in the through hole 120. The slider 210 is sleeved on the outer peripheral surface of the smooth portion of the first slider 220 through the through hole at the top, and the bottom of the slider 210 is clamped on the second slider 230.

[0067] The connection between the second plate body 102 and the connecting plate body 103 is recessed in a preset direction to form a hinge groove 110 at the connection between the second plate body 102 and the connecting plate body 103, and the preset direction is perpendicular to both the extension direction of the axis of the first guide hole 130 and the extension direction of the center line of the through hole 120, and the connecting rod 150 is fixedly connected to the bottom surface of the hinge groove 110.

[0068] The conductive rod 300 is rotatably connected to the base 100, and the conductive rod 300 includes a conductive tube 310 and a connecting block 320. The conductive tube 310 is fixedly connected to the connecting block 320. The groove wall surface of the connecting block 320 close to the side hinge groove 110 of the base 100 is an arc surface. The hinge groove 110 is fixedly connected with a connecting rod 150. The connecting block 320 is sleeved on the outer peripheral surface of the connecting rod 150 through a through hole so that the conductive rod 300 is rotatably connected to the base 100. The top surface of the connecting block 320 is a convex arc surface, and there is a gap between the top surface of the connecting block 320 and the groove wall surface of the hinge groove 110 that abuts against the base 100.

[0069] The protective cover 400 covers the surfaces of the base 100 and the conductive rod 300 .

[0070] Specifically, the widest surface of the power busbar may be parallel to the horizontal plane or perpendicular to the horizontal plane, and the base 100 and the conductive rod 300 can rotate relative to each other, so that the emergency power supply device can operate in various positions of the power busbar. The thickness and the area of ​​the widest surface of the power busbar are different, and the size of the power busbar engaged by the slider 210 and the base 100 can be adjusted.

[0071] More specifically, the top of the through hole 120 of the base 100 is provided with a bite tooth, and the top of the slider 210 is provided with a bite tooth, and the mutual bite of the bite teeth can enhance the connection strength between the emergency power supply device and the power supply busbar. The inner cavity of the conductive tube 310 is provided with a clamping rod 500 to clamp the joint of the power supply and the power supply cable.

[0072] In fact, a slide groove is provided at the bottom of the slider 210, and a clamping head is provided at the end of the second slide rod 230, and the clamping head is clamped in the slide groove.

[0073] During the assembly process, the second slide rod 230 passes through the second guide hole 140 to expose the clamping head, and the slider 210 enters the through hole 120 along the extension direction of the through hole 120. At the same time, the slide groove is clamped in the clamping head, and the first slide rod 220 is slidably connected with the slider 210 through the first guide hole 130.

[0074] The present application relates to an emergency power supply device, in which a slider 210 is accommodated through a through hole 120 of a base 100. In fact, the through hole 120 penetrates the side wall of the base 100 that is relatively arranged between the top surface and the bottom surface of the base 100. The first slide bar 220 serves as a guide bar for the slider 210. When the second slide bar 230 abuts against the slider 210 and gives a thrust to the slider 210, the first slide bar 220 guides the slider 210 to approach the top surface of the base 100. The process of the slider 210 approaching the top surface of the base 100 is the process of the emergency power supply device engaging the power supply busbar. The hinge groove 110 is rotatably connected to the connecting block 320 through the connecting rod 150. The connecting block 320 can be fixedly connected to the conductive tube 310 and guide the current.

[0075] In fact, the rotational connection between the connection block 320 and the base 100 can make the emergency power supply device adapt to power supply busbars of different specifications and different working states. This application solves the defect that the traditional emergency power supply device cannot cope with power supply busbars of different specifications and different working states.

[0076] like Figure 1 As shown, in one embodiment of the present application, the connecting rod 150 is provided with a threaded hole 151. The threaded hole 151 of the connecting rod 150 is threadedly connected with a bolt 152. The bolt 152 includes a nut 153 and a screw rod 154. The nut 153 and the screw rod 154 are fixedly connected. The diameter of the nut 153 is larger than the diameter of the connecting rod 150.

[0077] Specifically, the rotational connection between the base 100 and the connecting block 320 also requires the base 100 to be electrically connected to the connecting block 320. Therefore, the base 100 and the connecting block 320 need to be tightly abutted. The diameter of the nut 153 is larger than the diameter of the connecting rod 150, which ensures that the hinge groove 110 is tightly abutted against the side wall of the connecting block 320. The tightly abutted base 100 and the connecting block 320 improve the conductivity of the emergency power supply device.

[0078] The present application relates to an emergency power supply device, wherein the hinge slot 110 is rotatably connected to the connection block 320 through the connection rod 150, and the connection block 320 can be fixedly connected to the conductive tube 310 and guide the current. In fact, the rotational connection between the connection block 320 and the base 100 can enable the emergency power supply device to adapt to power supply busbars of different specifications and different working states. The present application solves the defect that the traditional emergency power supply device cannot cope with power supply busbars of different specifications and different working states.

[0079] like Figure 1As shown, in one embodiment of the present application, the protective cover 400 includes a first sub-portion 410. The first sub-portion 410 is sleeved on the outer peripheral surface of the connecting block 320. A notch 311 is provided at one end of the conductive tube 310 close to the connecting block 320. A retaining spring 411 is clamped in the inner cavity of the first sub-portion 410. The retaining spring 411 is clamped at the connecting portion between the conductive tube 310 and the connecting block 320 through the notch 311.

[0080] Specifically, during the assembly process, the first sub-portion 410 is sleeved along the connecting block 320 toward the conductive tube 310. The first sub-portion 410 has reserved holes for bolts 152, through which the bolts 152 connect the base 100 and the connecting block 320 for rotation.

[0081] like Figure 4 As shown, in one embodiment of the present application, the protective cover 400 further includes a second sub-portion 420. The second sub-portion 420 is sleeved on the conductive tube 310. The second sub-portion 420 abuts against the retaining spring 411. A recoil spring 421 is provided between the inner circumference of the second sub-portion 420 and the outer circumference of the conductive tube 310. The axis of the recoil spring 421 coincides with the axis of the conductive tube 310.

[0082] Specifically, the clamping spring 411 can be removed through the notch 311 and inserted into the connection portion between the conductive tube 310 and the connection block 320 .

[0083] like Figure 1 As shown, in one embodiment of the present application, the second sub-portion 420 includes a retaining ring plate 422. The retaining ring plate 422 is fixedly connected to the inner wall of the second sub-portion 420. The retaining ring plate 422 abuts against the bottom of the retaining spring 411. The retaining ring plate 422 is disposed between the retaining spring 411 and the recoil spring 421.

[0084] Specifically, the return spring 421 and the retaining spring 411 support the retaining ring plate 422 to fix the retaining ring plate 422. The retaining ring plate 422 is fixedly connected to the inner wall of the second sub-portion 420, and the return spring 421 and the retaining spring 411 further fix the second sub-portion 420.

[0085] like Figure 4 As shown, in one embodiment of the present application, the inner diameter of the retaining ring plate 422 is greater than the outer diameter of the conductive tube 310. The inner diameter of the retaining ring plate 422 is smaller than the outer diameter of the retaining spring 411. The inner diameter of the retaining ring plate 422 is smaller than the outer diameter of the recoil spring 421. The inner diameter of the second sub-portion 420 is greater than the outer diameter of the recoil spring 421.

[0086] Specifically, the size of the recoil spring 421, the clamping ring plate 422, the clamping spring 411, and the second sub-portion 420 is limited, not only to ensure that the recoil spring 421 and the clamping spring 411 support the clamping ring plate 422, but also to facilitate assembly. More specifically, the second sub-portion 420 abuts against the clamping spring 411 through the clamping ring plate 422. In the actual assembly process, the second sub-portion 420 is sleeved on the conductive tube 310, and the recoil spring 421 is then sleeved on the conductive tube 310 to complete the mechanical assembly process of this part.

[0087] like Figures 1 to 4 As shown, in one embodiment of the present application, the emergency power supply device further includes a support ring 423 and a retaining ring 424. The support ring 423 is sleeved on the outer peripheral surface of the conductive tube 310. The return spring 421 is arranged between the support ring 423 and the retaining ring plate 422. The conductive tube 310 is provided with an annular groove 425. The annular groove 425 is arranged away from the connecting block 320. The retaining ring 424 is retained in the annular groove 425. The support ring 423 is in contact with the retaining ring 424.

[0088] Specifically, the clamping ring 424 is used to abut and lock the abutting ring 423 on the outer circumference of the conductive tube 310. The abutting ring 423 is used to abut one end of the recoil spring 421 to ensure that one end of the recoil spring 421 abuts against the abutting ring 423 and the other end of the recoil spring 421 abuts against the clamping ring plate 422.

[0089] In fact, one function of the return spring 421 is to fix the second section 420 on the outer circumference of the conductive tube 310 .

[0090] This embodiment relates to the second sub-portion 420. The second sub-portion 420 is fixed to the outer peripheral surface of the conductive tube 310, and one function is to protect the operator from electric shock.

[0091] like Figure 4 As shown, in one embodiment of the present application, the second division 420 is provided with a receiving hole 426. The receiving hole 426 is provided with a retaining bead 427. The retaining bead 427 is abutted against the outer circumference of the abutment ring 423. The protective cover 400 also includes a third division 430. The third division 430 is sleeved on the outer circumference of the second division 420. The third division 430 is provided with a retaining groove 431. When the retaining bead 427 is accommodated in the retaining groove 431, the retaining ring 424 can slide freely relative to the recoil spring 421.

[0092] Specifically, the retaining bead 427 is disposed in the accommodating hole 426 , one end of the retaining bead 427 abuts against the outer peripheral surface of the abutting ring 423 , and the other end of the retaining bead 427 abuts against the third section 430 provided with a clamping groove 431 .

[0093] When the stopper bead 427 abuts against the clamping groove 431 provided in the third sub-portion 430, the abutting ring 423 can move along the outer peripheral surface of the conductive tube 310 and toward the clamping ring plate 422 to accommodate the joint of the power supply and the power supply cable, and make the joint of the power supply and the power supply cable clamp the clamping rod 500 provided in the inner cavity of the conductive tube 310. In fact, another function of the return spring 421 is to provide a reduction amount for the joint of the power supply and the power supply cable to extend into the inner cavity of the conductive tube 310.

[0094] On this basis, it can be understood that:

[0095] like Figure 1 As shown, in one embodiment of the present application, a positioning post 432 is provided on the outer circumference of the second sub-section 420. A positioning groove 433 is provided on the third sub-section 430. The positioning post 432 is inserted into the positioning groove 433 so that the relative positional relationship between the second sub-section 420 and the third sub-section 430 in the tangent direction of the outer circumferential surface of the third sub-section 430 remains unchanged.

[0096] Specifically, the third sub-section 430 is sleeved on the outer circumference of the second sub-section 420. When the third sub-section 430 slides along the outer circumference of the second sub-section 420, the third sub-section 430 will rotate along the axial center axis of the third sub-section 430. At this time, the positioning column 432 is inserted into the positioning groove 433, ensuring that the retaining bead 427 is disengaged from the track of the rotation trend of the locking groove 431. That is, the locking groove 431 can only slide along the axial center axis of the third sub-section 430.

[0097] When the locking groove 431 slides along the axial center axis of the third sub-portion 430 , the third sub-portion 430 locks the stopper bead 427 , thereby improving the connection strength between the joint of the power supply and the power supply cable and the conductive tube 310 .

[0098] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
