Specific embodiment

Referring to figs. 1 to Fig. 5 it is found that the utility model: a kind of electronic counter, including ontology 1, display window 3 and fixinig plate 2, the ontology 1 includes shell 11 and counting component, and the counting component includes wiring board 12, is located at 12 both ends of wiring board And display screen 13 and rear cover 14 normal thereto, the rear cover 14 are equipped with limit fastener 4 and connecting terminal 5；On wiring board 12 Equipped with component is counted, 13 grades of counting element, display screen rear covers 14 are respectively positioned on the same side of wiring board 12, the structure setting Structure is clean and tidy, and when being inserted into shell 11, contraposition is accurate, and installation quickly, improves operating efficiency.It states on 11 upper and lower surface of shell respectively Arrangement is equipped with limit hole 6 and limiting slot corresponding with limit hole 6, is equipped with skid-proof regions 7 and hole 41 on the two sides of left and right；Shell 11 It is fixedly arranged at the front end with the panel 31 equipped with display window 3, holding is detachably connected fixinig plate 2, fixinig plate 2 on the upper and lower surface of panel 31 Trapezoidal raised 22 for being equipped with fixation hole 21 and matching with limit hole 6 and limiting slot pass through elastic rope between two fixinig plates 2 8 connections.The fixation hole 21 is for wearing screw and then being fixed on equipment or rack.

Trapezoidal raised 22 side is equipped with slot 91, is fixed with piece 9 by elastic component 92 in slot 91, and described 9 separate Sheet rubber 93 is posted on the one side of slot 91, described 9 parallel with the trapezoidal raised 22 setting face of slot 91.Pass through elastic component 92 push jacks 9 drive sheet rubber 93 and the side wall of limit hole 6 or limiting slot to fit closely, and are connected firmly, and avoid shell 11 and fix It is opposite between piece 2 to shake.

The left and right sides of panel 31 are respectively equipped with bar shaped groove 32.Bar shaped groove 32 is whole for placing elastic rope 8 Beauty, protection elastic rope 8 are not damaged.

The connecting terminal 5 is located at side of the rear cover 14 far from wiring board 12.

Button switch 33 is additionally provided on the panel 31.

Transparent glass is housed, while protecting display screen 13, it can be observed that the note on display screen 13 at the display window 3 Record numerical value.When installation, display screen 13 is contradicted on transparent glass.

The skewed slot 71 that bottom is directed away from 3 direction of display window is equipped at the skid-proof regions 7, and skewed slot 71 is uniformly distributed.? During assembling electronic counter, skid-proof regions 7 are pinched for left hand thumb and index finger pressing, and the right hand holds rear cover 14, will be counted In component plug to shell 11, until limit fastener 4 is placed in hole 41, the inclined direction of skewed slot 71 is identical as left hand Impact direction, Increase frictional force, places left-hand finger and occur to slide relatively with skid-proof regions 7, using effect is good.

The limit hole 6 and limiting slot are to be arranged with trapezoidal raised 22 corresponding trapezium structure, equipped with limiting slot The face of shell 11 fits with wiring board 12 during installation, and the face of the shell 11 of limit hole 6 is arranged far from wiring board 12, setting limit The thickness in the face of the shell 11 of position slot is greater than the thickness in the face of the shell 11 of setting limit hole 6, and limiting slot is made not influence wiring board 12。

Specifically, when mounting groove is deep enough in equipment, fixinig plate 2 is located at position as shown in Fig. 1, i.e., on fixinig plate 2 Trapezoidal raised 22 be placed in 31 upper groove of panel, fixinig plate 2 and display window 3 are in the same plane；Ontology 1 is placed in equipment In mounting groove, fixinig plate 2 is mutually posted with equipment, and screw is screwed or followed closely across fixation hole 21 and is set in equipment, electronic counter Be installed.It is limited when installing groove depth in equipment, as shown in Fig. 2, according to the depth of mounting groove in equipment, determines and fix The position that piece 2 is fixed removes two opposite fixinig plates 2 from panel 31, is respectively placed in opposite limit hole 6 and limiting slot It is interior, distance of the depth of mounting groove not less than fixinig plate 2 at this time to 14 upper connecting terminal 5 of rear cover in equipment, it is ensured that when installation, Gu Stator 2 is affixed with equipment surface.During fixinig plate 2 is mobile, the elastic rope 8 between two fixinig plates 2 is in quilt always Tensional state prevents fixinig plate 2 from falling, while elastic telescopic 8 is also to trapezoidal raised 22 holding of two fixinig plates 2 in opposite limit Reference by location is provided in position hole 6 and limiting slot, opposite limit hole 6 and limiting slot is quickly found accurately, saves the time.

The utility model effectively improves existing electronic counter installation inconvenience and electronic counter assembly operation Complicated problem, the electronic counter is reasonable in design simple, is arranged by the removable frame of fixinig plate 2, electronic counting Device is not limited by mounting groove or hole depth, and electronic counter can be securely fixed to installation；Simultaneously by limit fastener 4 with The cooperation in hole 41 settles the assembling of electronic counter at one go, and securely, is easy to remove and repair or safeguards.

Every technical staff's notice: although the utility model is described according to above-mentioned specific embodiment, this The invention thought of utility model is not limited to that utility model, and any repacking with inventive concept will all be included in this specially In sharp scope of patent protection.
