Description

Technical Field

[0001] The invention relates to the technical field of wiring maintenance equipment, and in particular to an audio distribution frame fuse plugging and unplugging tool and a construction method. Background Art

[0002] As an effective means of managing wired telephones and various 64K analog signal services, and effectively ensuring the independence and confidentiality of the services, external line-side audio patch panel fuses have been widely used. The fuse models plugged on them are roughly the same in shape, with slightly different sizes. With the tight space resources in the computer room, the size of the fuses has tended to shrink in recent years, and the fuse models, shell structures and sizes produced by different manufacturers are inconsistent.

[0003] In order to enhance the reliability of the fuse, the pressure and friction during the process of inserting the fuse into the audio wiring module are relatively large. It is often difficult to push it in and pull it out by hand. Sometimes the operation and maintenance personnel are in a hurry and perform violent construction, which often causes the fuse to be damaged and cracked, or even the audio wiring to be pulled off.

[0004] At present, there is no effective solution to the above problems, so it is urgent to design an audio patch panel insurance plug-in tool to break the outdated thinking, expand the operation method of the process, and improve the quality of audio patch panel operation and maintenance. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to provide an audio patch panel fuse plugging and unplugging tool and a construction method. The tool solves the defects of the existing pure manual operation and has wide promotion and application space.

[0006] An audio patch panel fuse plugging and unplugging tool comprises a handle, one end of the handle is movably connected with a clamping unit which can adjust the spacing in opposite directions and provide a flexible clamping force for the audio patch panel fuse so as to remove the fuse, the other end of the handle is compositely bonded with a rubber pad which can provide a flexible pushing force for the audio patch panel fuse so as to plug and install the fuse, and the handle is fixed with a hanging ring which is convenient for hanging and receiving and carrying the plugging and unplugging tool.

[0007] Preferably, the clamping unit comprises a fixed clamping frame and a movable clamping frame, wherein the fixed clamping frame is fixedly arranged at the end of the handle, and the movable clamping frame is slidably and elastically limitedly connected to one side of the end of the handle;

[0008] A sliding rod is vertically fixed at the root of the movable clamp frame, which radially penetrates and is slidably connected to the front end of the handle. A preload spring is sleeved on the upper part of the sliding rod, and a gasket is axially pressed and connected to the top of the sliding rod through a preload adjustment nut connected by threaded engagement; one end of the preload spring is elastically supported on the outer wall of the handle, and the other end of the preload spring is elastically supported on the axial end face of the gasket.

[0009] Preferably, clamping buffer pads are fixedly provided on the clamping ends of the fixed clamping frame and the movable clamping frame.

[0010] A construction method for an audio distribution frame fuse plugging and unplugging tool comprises the following steps:

[0011] When pulling out the insurance, first press down the clamping buffer pad of the fixed clamp frame to position it on the top surface of the insurance shell, then rotate the movable clamp frame to the bottom surface of the insurance shell with the slide bar as the axis, and finally tighten the preload adjustment nut to put the preload spring in a compressed state until the clamping buffer pads of the fixed clamp frame and the movable clamp frame are respectively attached and clamped on the top and bottom surfaces of the insurance shell, and adjust the clamping force output by the fixed clamp frame and the movable clamp frame and the maximum stroke spacing through the preload adjustment nut to ensure that sufficient static friction is generated between the insurance shell and the insurance shell when the insurance is pulled out;

[0012] When installing the fuse, initially align the fuse with the socket of the audio patch panel, and then use the handle with a rubber pad to push the end of the fuse until the fuse is firmly inserted into the socket.

[0013] The advantages and technical effects of the present invention are:

[0014] The present invention discloses an audio distribution frame fuse plugging and extraction tool and a construction method. The opening positions of a fixed clamp frame and a movable clamp frame are adjusted by pressing a pre-tightening adjustment nut, so that a clamping buffer pad can penetrate into and fit with the audio distribution fuse head. Subsequently, the pre-tightening adjustment nut is loosened to clamp the fixed clamp frame and the movable clamp frame. The fuse is clamped by parallel movement of the movable frame toward the fixed frame. The movable frame can be rotatably connected to the end of a handle with a sliding rod as the axis, so as to provide a space when the fuse size is large or adjacent fuses are densely plugged. In addition, the spacing between the movable clamp frame and the fixed clamp frame is adjusted by adjusting the axial connection position of the pre-tightening adjustment nut and the gasket on the sliding rod. Finally, the movable clamp frame and the fixed clamp frame are elastically clamped to the fuse housing by a pre-tightening spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Preferably, clamping buffer pads 9 are fixedly provided at the clamping ends of the fixed clamping frame and the movable clamping frame.

[0030] A construction method for an audio distribution frame fuse plugging and unplugging tool comprises the following steps:

[0031] When pulling out the insurance, first press down the clamping buffer pad of the fixed clamp frame to position it on the top surface of the insurance shell, then rotate the movable clamp frame to the bottom surface of the insurance shell with the slide bar as the axis, and finally tighten the preload adjustment nut to put the preload spring in a compressed state until the clamping buffer pads of the fixed clamp frame and the movable clamp frame are respectively attached and clamped on the top surface and bottom surface of the insurance shell, and adjust the clamping force output by the fixed clamp frame and the movable clamp frame through the preload adjustment nut to ensure that sufficient static friction is generated between the insurance shell and the insurance shell when the insurance is pulled out;

[0032] When installing the fuse, initially align the fuse with the socket of the audio patch panel, and then use the handle with a rubber pad to push the end face of the fuse until the fuse is firmly inserted into the socket.

[0033] In addition, the clamping ends of the fixed clamping frame, the movable clamping frame and a pair of clamping frames of the present invention can be designed as embracing clamping heads, which clamp the composite adhesive clamping buffer pads on the top and bottom surfaces of the fuse shell, and baffles are constrained on the left and right side surfaces of the fuse shell to isolate adjacent fuses.

[0034] In order to more clearly describe the specific embodiments of the present invention, several embodiments are provided below:

[0035] Embodiment 1, as Figures 1 to 3 As shown:

[0036] The clamping unit includes a fixed clamping frame and a movable clamping frame, wherein the fixed clamping frame is fixed at the end of the handle, and the movable clamping frame is slidably and elastically limitedly connected to one side of the end of the handle; a sliding rod is vertically fixed at the root of the movable clamping frame, which radially penetrates and is slidably connected to the front end of the handle, and a pre-tightening spring is sleeved on the upper part of the sliding rod, and a gasket is axially pressed and connected to the top end of the sliding rod through a pre-tightening adjustment nut connected by threaded engagement; one end of the pre-tightening spring is elastically supported on the outer wall of the handle, and the other end of the pre-tightening spring is elastically supported on the axial end face of the gasket.

[0037] When pulling out the safety, first press the clamping buffer pad of the fixed clamp frame down and position it on the top surface of the safety shell, then rotate the movable clamp frame to the bottom surface of the safety shell with the sliding rod as the axis, and finally tighten the preload adjustment nut to put the preload spring in a compressed state until the clamping buffer pads of the fixed clamp frame and the movable clamp frame are respectively attached and clamped on the top and bottom surfaces of the safety shell, and adjust the clamping force output by the fixed clamp frame and the movable clamp frame and the maximum stroke spacing through the preload adjustment nut to ensure that sufficient static friction is generated between the outer shell of the safety when the safety is pulled out.

[0038] When installing the fuse, initially align the fuse with the socket of the audio patch panel, and then use the handle with a rubber pad to push the end of the fuse until the fuse is firmly inserted into the socket.

[0039] Implementation 2, such as Figures 4 to 6 As shown:

[0040] The clamping unit comprises a pair of clamping frames hingedly connected to the ends of the handles in opposite directions, and an adjusting frame sleevedly connected to the outside of the pair of clamping frames and sliding forward and backward to adjust the opposite spacing between the clamping ends of the pair of clamping frames; a pin shaft at one end of the clamping frame is connected to the embedded groove at the front end of the handle, a vertically penetrating and horizontally extending clearance channel is provided inside the clamping frame, and a limit stopper is fixed on the inner wall of the clamping frame; a horizontally extending and vertically penetrating limit sliding hole is provided in the middle of the adjusting frame, and the limit sliding hole vertically penetrates and is horizontally slidably connected to a limit rod; the limit rod vertically penetrates the clearance channel inside the clamping frame, and the limit rod is provided with radial limit overlap by the limit stopper;

[0041] In the second embodiment, the clamping frame connected by opposite hinges provides clamping force for the fuse, so that the audio distribution frame can be pulled out after the fuse is clamped and fixed. The adjustment frame is slid on the outside of the two clamping frames to adjust the maximum spacing between the clamping ends of the two clamping frames. Finally, the limit rod sliding in the upper limit sliding hole of the adjustment frame is selected and an appropriate limit block is hung to fix the adjustment frame on the clamping frame, so that the clamping force of the clamping end of the clamping frame remains stable.

[0042] When pulling out the safety, first slide the adjustment frame to the root of the clamping frame to ensure that the clamping end of the clamping frame can be manually opened, and the opening angle is not less than the thickness of the outer shell of the safety, and then push the adjustment frame toward the clamping end of the clamping frame until the clamping buffer pad at the clamping end of the clamping frame is elastically clamped on the outer shell of the safety. When the clamping force is sufficient to ensure the static friction required when pulling out the safety, the adjustment limit rod is overlapped on the limit block on the inner wall of the clamping frame; preferably, the clamping frame is made of metal with certain elastic properties. When clamping the safety, the adjustment frame can be pushed to a limit block with a larger clamping force to hang the positioning limit rod, and the deformation of the clamping frame and the clamping buffer pad provide elastic clamping force.

[0043] In addition, the second implementation method of the second embodiment is: Figure 4 The pin-hinged connection between one end of the clamping frame and the end of the handle is changed to a fixed connection, the metal elastic deformation of the clamping frame is used to clamp the insurance shell, and the elastic deformation and clamping force of the clamping frame are provided by the adjustment frame sliding on the clamping frame. In addition, the handle is divided into two ends, which can be rotated to open, and the limit block can be inserted into the upper clamping frame and then rotated and fixed. In the locked position, the protruding part of the lower end of the limit block can overlap with the shielding part of the lower clamping frame, which plays a role in fixing the radial sliding of the limit block. The two clamping frames are bent and clamped in opposite directions by the metal elastic deformation of the limit block itself combined with the sliding constraint of the adjustment frame. Finally, preferably, the limit block is a consumable material and can be replaced after deformation after repeated use.

[0044] When installing the fuse, you only need to initially plug the fuse into the socket of the audio patch panel, and then use the handle with a rubber pad to push the end face of the fuse until the fuse is firmly inserted into the socket.

[0045] In addition, the present invention preferably, in the above two embodiments, the clamping buffer pads are horizontally fitted on the top and bottom surfaces of the fuse to provide a flexible and fitted static friction force, which is convenient for clamping and fixing the plug-in tool and the fuse outer shell; in addition, the clamping buffer pad can also be arranged to be vertically fitted on the top and bottom surfaces of the fuse, and the orientation design of this clamping buffer pad is suitable for embodiment one, that is, the surface contact translation clamping embodiment; in addition, the clamping buffer pad can also be designed as two oppositely arranged U-shaped clamps, which are clamped on the outer periphery of the fuse outer shell during opposite clamping, and rubber pads are compositely bonded on the side inner walls that fit the top and bottom surfaces of the fuse outer shell, so that not only the upper and lower end surfaces of the fuse shell can be clamped, but also the left and right sides of the fuse shell can be limited, which is convenient for pulling out the corresponding fuse on the audio distribution frame where the fuses are densely plugged in without being interfered by the adjacent plugged in fuses.

[0046] It should be noted that, in the first embodiment of the present invention, a movable clamping frame is used to rotate horizontally with the sliding rod as the axis to make way for the adjacent fuse, so as to facilitate the movable clamping frame to be positioned below the fuse to be plugged in and out, and finally a translational clamping method of a fixed clamping frame and a movable clamping frame is used to perform surface contact clamping on the fuse outer shell to avoid damage to the fuse shell due to concentrated clamping stress.

[0047] The second embodiment of the present invention adopts two clamping frames with hinged ends to clamp the outer shell of the fuse by the line contact principle of pliers, which is suitable for the working conditions where the outer shell of the fuse is small and adjacent fuses are plugged in very densely and it is difficult to avoid giving way.

[0048] Finally, all the parts not described in the present invention adopt mature products and mature technical means in the prior art.
