Abstract
The utility model discloses a plug withdrawal force measuring apparatus, comprising a base, an n-shaped support, a clamping apparatus, a steel wire rope and a weight, wherein the middle of the transverse rod of the top portion of the n-shaped support is provided with a hole used for getting the steel wire rope through, the clamping apparatus comprises two clamping plates and four adjusting screws, the n-shaped support is vertically arranged on the base, the clamping plates are fixedly connected with one end of the steel wire rope, and the weight are connected with the other end of the steel wire rope. One end of the steel wire rope is connected with the clamping apparatus for clamping a plug, the other end is connected with the weight, the plug can be pulled out through the gravity effect of the weight, and the gravity of the weight is the required maximum force to pull the plug out of a socket, thereby achieving the purpose of being simple in structure, convenient in use and accurate in withdrawal force measurement.
Description
Technical field
The utility model relates to the checkout equipment field, is specifically related to a kind of plug withdrawal force device.
Background technology
In daily life and work; Being connected of attaching plug and socket is modal appliances power source connected mode, yet, because plug and socket needs often plug; Just need plug and socket repeatedly still can contact firmly after the plug for a long time; Guarantee that the plug and socket contact is good, be easy to conduction, therefore; According to the relevant regulations of GB2099.1, IEC884-1 and other electric accessories, plug needed maximum, force and one pole latch when socket is extracted are extracted required minimum force from sleeve component and will be detected.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of simple in structure, easy to use and detect withdrawal force plug withdrawal force device accurately.
For achieving the above object, the technical scheme of the utility model is following:
A kind of plug withdrawal force device is made up of base, n shape support, clamping device, steel wire rope and counterweight; Be provided with the hole that is used to pass said steel wire rope in the middle of the said n shape support top cross bar; Said clamping device comprises two clamping plate and four set screw; Said n shape support is vertical on the said base; Said clamping plate are fixedly connected on said steel wire rope one end, and said counterweight is connected in the other end of said steel wire rope.
Preferably, side is provided with support bar between said n shape support two root posts.
Preferably, an end of said counterweight connection steel wire rope is provided with and is used to change and the hook that is connected counterweight.
Pass through technique scheme; The utility model connects the clamping device that clamps plug through the end with steel wire rope; The other end connects counterweight; Plug is extracted in action of gravity through counterweight, this moment counterweight the gravity needed maximum, force that is exactly plug when socket is extracted, thereby reached simple in structure, easy to use and detected withdrawal force purpose accurately.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of plug withdrawal force device, and its operation principle is through the action of gravity of counterweight plug to be extracted in socket, this moment required counterweight the minimum weight needed maximum, force that is exactly plug when socket is extracted.
Below in conjunction with embodiment and embodiment the utility model is done further detailed explanation.
Embodiment.
Like Fig. 1, shown in Figure 2, a kind of plug withdrawal force device is made up of base 1, n shape support 2, clamping device 3, steel wire rope 4 and counterweight 5; Be provided with the hole that is used to pass said steel wire rope 4 in the middle of the said n shape support top cross bar 21; Said clamping device 3 comprises two clamping plate 31 and four set screw 32; Said n shape support 2 is vertical on the said base 1; Said clamping plate 31 are fixedly connected on said steel wire rope 4 one ends, and said counterweight 5 is connected in the other end of said steel wire rope 4.Wherein, side is provided with support bar 6 between said n shape support two root posts 22; The end that said counterweight 5 connects steel wire rope 4 is provided with and is used to change and the hook that is connected counterweight 5 41.
Carrying out pull out force when detecting to inserting plug in the socket, as shown in Figure 2, the set screw 32 that at first will be positioned on the clamping plate 31 of clamping device 3 is unclamped; With plug place clamp in the two clamping plates 31 after; The set screw of screwing 32 clamps plug, and is as shown in Figure 1, and then ascending replacement is one by one hung counterweight 5 on the hook 41 of being located at steel wire rope 4 one ends; Fall up to counterweight; Plug is extracted in socket, and according to the principle of active force and reaction force, the counterweight weight of the minimum that can extract plug this moment is exactly the withdrawal force of plug from socket.
Can find out from the operation principle of a kind of plug withdrawal force device of above employing the utility model; End through with steel wire rope 4 connects the clamping device 3 that clamps plug; The other end connects counterweight 5; Plug is extracted in action of gravity through counterweight 5, this moment counterweight 5 the gravity needed maximum, force that is exactly plug when socket is extracted, thereby reached simple in structure, easy to use and detected withdrawal force purpose accurately.
To the above-mentioned explanation of disclosed plug withdrawal force device embodiment, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
