Abstract
The utility model discloses a foldable self-locking handle, which comprises a ball, a cushion plate, a handle and a shaft. The handle and the cushion plate are connected with each other through the shaft in a rotating way; a thread projecting part and a through hole projecting part are arranged on the cushion plate; the shaft end is provided with threads and is fastened on the thread projecting part; a ball consists of a ball cap and a spring; the spring is arranged in the ball cap; the ball cap and the spring are packaged in a hollow cavity of the handle through a cover plate; and the head part of the ball cap is embedded in a hole of the through hole projecting part under the function of the spring. The handle is folded and arranged on a side plate of a chassis, and the handle can also be embedded in an inner wall of the chassis, therefore, the installation space is saved, and the handle conforms to human-machine engineering.
Description
Technical field
The utility model belongs to electronic devices structure, particularly a kind of collapsible self-locking handle.
Background technology
The radar cabinet needs mounting knob annex on cabinet for ease of turnover.Present stage radar cabinet handle to be mainly U-shaped fixed, be fixed in the front and rear portions of cabinet according to demand.When master-plan, need to consider the protrusion installation dimension of this part, in small space (as shelter, cabin), easy hook operator, and because designing requirement, case front panel requires cloth dress electric connector, the installation site of handle needs special design, and for satisfying load-bearing and appearance requirement, this handle requires to occur in pairs simultaneously, thereby influence the global design of cabinet, be difficult to realize the coordination layout of cabinet panel.The moulding of this kind handle is simple, and the operation contact site considers that without crossing human engineering feel is poor during use, and long-time use is easily slipped out of the hand.Because above-mentioned factor, it is good newly to develop a kind of human engineering, and good looking appearance requires few handle to global design.
The utility model content
The purpose of this utility model is to provide a kind of collapsible self-locking handle.
The technical scheme that realizes the utility model purpose is: a kind of collapsible self-locking handle, comprise ball, backing plate, handle, axle composition, handle is rotatably connected by axle with backing plate, and screw thread protuberance and through hole protuberance are set on the backing plate, the axle head car has screw thread, is anchored on the screw thread protuberance; Ball is made up of ball cap and spring, and spring is contained in the ball cap, and ball cap and spring are packaged in by cover plate in the cavity of handle, and when handle was closed, the head of ball cap embedded in the hole of through hole protuberance under the effect of spring.
The utility model compared with prior art, its remarkable advantage is: (1) handle handle is realized folding, is installed on cabinet side board, but also coil insertion device chamber interior wall is saved installing space, handle meets human engineering.(2) for satisfying carrier aircraft requirement such as aircraft, in light weight, single supporting power big (≮ 50Kg) under abominable flight environment of vehicle, realizing self-locking, effectively avoid the wearing and tearing of cabinet side board painted surface and reduce noise.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the collapsible self-locking handle of the utility model.
Fig. 2 is the ball generalized section.
Embodiment
In conjunction with Fig. 1 and Fig. 4, the collapsible self-locking handle of the utility model comprises ball 1, backing plate 2, handle 3, axle 4 compositions, handle 3 is rotatably connected by axle 4 with backing plate 2, screw thread protuberance and through hole protuberance are set on the backing plate 2, and axle 4 end cars have screw thread, are anchored on the screw thread protuberance; Ball 1 is made up of ball cap 1-1 and spring 1-2, spring 1-2 is contained in the ball cap 1-1, ball cap 1-1 and spring 1-2 are packaged in by cover plate in the cavity of handle 3, and during handle 3 closures, the head of ball cap 1-1 embeds in the hole of through hole protuberance under the effect of spring 1-2.Only need handle 3 is mentioned, ball 1 is slided in the hole, and handle 3 promptly is unlocked, and as handle 3 is incorporated into to backing plate 2 positions, ball 1 slips in the hole, and handle is locked, as schemes shown in Figure 2.
Wherein, on the backing plate 2 installing hole is set.Axle 4 is by the stainless steel turning moulding, and the remaining parts material is aluminium alloy, and the surface applies paint as required.Spring 1-2 selects cylindroid helical-coil compression spring for use, and the spring wire diameter d is 0.5～1mm, curls up than being recommended as 5～12.
Suppose that cabinet is 50kg, in the handling process, the shape of handle has influenced operator's feel, and cabinet weight is heavy more, and the operator reins in hand more when gripping.The design of this handle is from human engineering, and handle is according to the staff shaped design, and at the equal rounding in the corner of holding area.According to the human body limb strength of ergonomics introduction, when the people stands, the pulling force difference that is produced when arm is finished different angles.With the body weight is that 50kg is an example, and when carrying handle, arm becomes about 60 with health.Angle, the pulling force that arm stretches is 15% of a body weight, and the power that produces of moving up and down be equivalent to before and after push-and-pull 1/3, can get the maximum pull that human body can apply when carrying handle is 25N.
Handle is designed novel handle, is fixed in cabinet side board with four M4 sunk screws, and backing plate sinks to the cabinet sidewall, and present condition is closed, as need carrying turnover, handle is lifted from backing plate can use.
