Description

Technical Field

[0001] The utility model belongs to the technical field of fire signal butterfly valves, and particularly relates to a fire signal butterfly valve which is convenient for wiring. Background Art

[0002] In the field of fire safety, the fire signal butterfly valve is a control valve used in fire protection systems. It is usually installed on fire protection pipes and plays an important role in controlling water flow and transmitting signals. As an important part of the fire protection system, the signal butterfly valve mainly controls the on and off of water flow to ensure the normal operation of fire protection facilities. When the fire signal butterfly valve is used, it is generally rotated by the valve plate of the controller butterfly valve, so that the water flow can be opened and closed, thereby controlling the flow of fire protection water.

[0003] However, the controller needs to be wired before use. The traditional wiring method is generally to insert the wire into the terminal and then crimp and fix it by rotating the bolt.

[0004] However, this method can only apply a longitudinal compression force to the wire. In actual use, the wire may also be affected by external factors such as external force or vibration, which may cause it to loosen or even fall off, seriously affecting the transmission of fire signals and the normal operation of the butterfly valve.

[0005] On the other hand, the existing fire signal butterfly valve wiring design also has certain challenges in terms of reliability. Due to loose wiring, it may cause signal loss, false alarms or other failures, which undoubtedly poses a potential threat to the stability and safety of the fire protection system.

[0006] To this end, we have proposed a fire signal butterfly valve that is easy to wire. The device can clamp the wires horizontally and press them vertically, making it difficult for the wires to fall off, thereby improving the fixing effect of the wires. Utility Model Content

[0007] The utility model aims to provide a fire signal butterfly valve which is convenient for wiring. The device can clamp the wires transversely and press them longitudinally, so that the wires are not easy to fall off, thereby improving the fixing effect of the wires.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A fire signal butterfly valve convenient for wiring comprises a butterfly valve body, a control box is arranged on the butterfly valve body, and a wiring assembly is arranged on the control box;

[0010] The wiring assembly includes a plurality of hollow conical shells arranged on the control box, each of the hollow conical shells is provided with through holes on both sides for allowing the wires to enter, and a conductive sheet is provided on the bottom inner wall of the hollow conical shell, each of the hollow conical shells is provided with a rotating assembly, a longitudinal pressure plate is provided on the rotating assembly, a first slide groove is provided on both sides of the longitudinal pressure plate, a moving assembly is provided inside the first slide groove, and a transverse trapezoidal fixing plate is provided on the moving assembly, and the inclined surface of the transverse trapezoidal fixing plate slides on the inner wall of the hollow conical shell.

[0011] Furthermore, the hollow conical shell is wider at the top and narrower at the bottom.

[0012] Furthermore, a second slide groove is provided on the hollow conical shell, a second slide block is provided inside the second slide groove, and one side of the second slide block is connected to the transverse trapezoidal fixing plate.

[0013] Furthermore, the longitudinal pressing plate and the transverse trapezoidal fixing plate are both provided with anti-slip surfaces.

[0014] Furthermore, the rotating assembly includes a rotating hole opened on the hollow conical shell, a rotating rod is arranged inside the rotating hole, a thread is arranged on the rotating rod located at the hollow conical shell, the thread is threadably connected to the longitudinal pressure plate, and a rotating disk is installed on the top of the rotating rod.

[0016] The technical effects achieved by this utility model are:

[0017] First, the wire on the butterfly valve body is passed through one of the through holes into the hollow conical shell and contacts one end of the conductive sheet, and then the external wire is passed through another through hole into the hollow conical shell and contacts the other end of the conductive sheet, and then the rotating assembly is rotated, and the rotating assembly drives the longitudinal pressure plate to move downward when rotating, so as to longitudinally press and fix the wire on the butterfly valve body and the external wire, and at the same time, when the longitudinal pressure plate moves downward, it drives the transverse longitudinal fixing plate to move downward. Since the inclined surface of the transverse trapezoidal fixing plate fits the inner wall of the hollow conical shell, the two transverse trapezoidal fixing plates drive the moving assembly to move relative to each other when moving, and then the wire on the butterfly valve body and the external wire are transversely clamped and fixed. The device can transversely clamp and longitudinally press the wire, and the wire is not easy to fall off, thereby improving the fixing effect of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-5 As shown, the technical solution adopted by the utility model is specifically as follows: a fire signal butterfly valve which is easy to connect, comprising a butterfly valve body 1, a control box 2 is arranged on the butterfly valve body 1, and a wiring assembly is arranged on the control box 2;

[0027] The wiring assembly includes a plurality of hollow conical shells 3 arranged on the control box 2, each hollow conical shell 3 is provided with through holes 4 for the wires to enter on both sides, and a conductive sheet 5 is provided on the inner wall at the bottom of the hollow conical shell 3, and each hollow conical shell 3 is provided with a rotating assembly, a longitudinal pressure plate 6 is provided on the rotating assembly, and first slide grooves 7 are provided on both sides of the longitudinal pressure plate 6, a moving assembly is provided inside the first slide groove 7, and a transverse trapezoidal fixing plate 8 is provided on the moving assembly, and the inclined surface of the transverse trapezoidal fixing plate 8 slides on the inner wall of the hollow conical shell 3.

[0028] Its working principle is as follows: first, the wire on the butterfly valve body 1 enters the hollow conical shell 3 through one of the through holes 4 and contacts one end of the conductive sheet 5, then the external wire enters the hollow conical shell 3 through another through hole 4 and contacts the other end of the conductive sheet 5, and then the rotating assembly is rotated, and the rotating assembly drives the longitudinal pressing plate 6 to move downward when rotating, so as to longitudinally press and fix the wire on the butterfly valve body 1 and the external wire, and at the same time, when the longitudinal pressing plate 6 moves downward, it drives the transverse longitudinal fixing plate to move downward. Since the inclined surface of the transverse trapezoidal fixing plate 8 fits the inner wall of the hollow conical shell 3, the two transverse trapezoidal fixing plates 8 drive the moving assembly to move relative to each other when moving, and then the wire on the butterfly valve body 1 and the external wire are transversely clamped and fixed. The device can perform transverse clamping and longitudinal pressing of the wire, and the wire is not easy to fall off, thereby improving the fixing effect of the wire.

[0029] The hollow conical shell 3 is wide at the top and narrow at the bottom. This arrangement enables the transverse trapezoidal fixing plate 8 to move relatively when moving, thereby clamping the wire.

[0030] Meanwhile, a second slide groove 9 is provided on the hollow conical shell 3 , a second slide block 10 is provided inside the second slide groove 9 , and one side of the second slide block 10 is connected to the transverse trapezoidal fixing plate 8 .

[0031] When the transverse trapezoidal fixing plate 8 moves, the second sliding block 10 is driven to move inside the second sliding groove 9, thereby performing relative movement.

[0032] In order to prevent the wires from sliding when they are fixed, anti-slip surfaces are provided on the longitudinal pressing plate 6 and the transverse trapezoidal fixing plate 8, and the anti-slip surfaces can prevent the wires from sliding when they are fixed.

[0033] The conductive sheet 5 is a conductive copper sheet in the prior art, which can be powered on and work when in contact with the wire. It belongs to the prior art and will not be described in detail here.

[0034] The through holes 4 are arranged so that only wires can enter. The two through holes 4 correspond to the wires in the outside world and the wires on the butterfly valve body 1, so that they are connected and work can be performed.

[0035] like Figure 2-4 As shown, the rotating assembly includes a rotating hole opened on the hollow conical shell 3, a rotating rod 11 is arranged inside the rotating hole, and the rotating rod 11 is provided with a thread at the position of the hollow conical shell 3, the thread is threadedly connected to the longitudinal pressure plate 6, and a rotating disk 12 is installed on the top of the rotating rod 11.

[0036] The rotating rod 11 is driven to rotate in the rotating hole by the rotating disk 12 , and the rotating rod 11 drives the longitudinal pressing plate 6 to move downward when rotating, so as to fix the wire.

[0037] The moving assembly includes a fixed shaft 13 arranged inside the first slide groove 7, on which a first slider 14 and a spring 15 are sleeved, one side of the first slider 14 is connected to the spring 15, and a connecting rod 16 is arranged on the first slider 14, which is connected to the transverse trapezoidal fixed plate 8.

[0038] When the transverse trapezoidal fixed plate 8 moves, the connecting rod 16 is driven to move the first slider 14 on the fixed shaft 13 to squeeze the spring 15, thereby completing the contraction and moving, so that relative movement can be performed.

[0039] The first sliding block 14 is matched with the first sliding groove 7 , and the matching here means that the first sliding block 14 can move smoothly inside the first sliding groove 7 without getting stuck.

[0040] The working principle of the utility model is as follows: firstly, the wire on the butterfly valve body 1 enters the hollow conical shell 3 through one of the through holes 4 and contacts one end of the conductive sheet 5, then the wire from the outside enters the hollow conical shell 3 through another through hole 4 and contacts the other end of the conductive sheet 5, then the rotating assembly is rotated, and the rotating assembly drives the longitudinal pressing plate 6 to move downward when rotating, so as to longitudinally press and fix the wire on the butterfly valve body 1 and the wire from the outside, and at the same time, when the longitudinal pressing plate 6 moves downward, it drives the transverse longitudinal fixing plate to move downward, and since the inclined surface of the transverse trapezoidal fixing plate 8 fits the inner wall of the hollow conical shell 3, the two transverse trapezoidal fixing plates 8 drive the moving assembly to move relative to each other when moving, and then transversely clamp and fix the wire on the butterfly valve body 1 and the wire from the outside. The device can transversely clamp and longitudinally press the wire, and the wire is not easy to fall off, thereby improving the fixing effect of the wire.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
