Abstract
The utility model discloses a locking handle, which mainly comprises a handle and locking wheel components. The locking wheel components are respectively arranged at the two ends of the handle in a symmetric way, are connected with the two ends of the handle through riveting or interference fit and are formed by mainly connecting a rotating handle and two positioning clamps fixing the rotating handle, the two ends and the middle part of the positioning clamps are respectively provided with a through hole, and the rotating handle is provided with a through hole corresponding to two through holes on the positioning clamps, is clamped between the two positioning clamps to form a clamping wall, and is fixed through a rivet penetrating through the corresponding through holes on the positioning clamps and the rotating handle. The utility model has simple structure and adopts rolling friction due to the roller cantilever locking mode. Moreover, the utility model can lock reliably with small force and good elasticity.
Description
Technical field
The utility model relates to the connector of appliance field, specifically relates to the connector of industrial equipment, city rail and bullet train appliance field, the set lever that uses on especially a kind of rectangular electric connector.
Background technology
Electric connector is electrically connected and the signal transmission between device and device, assembly and assembly, system and system, is to constitute the necessary base components of holonomic system.The housing of general connector connects and adopts screw to connect or other similar handle connects, and makes quite difficulty of connector dismounting inconvenience or dismounting, is unfavorable for changing, and maintenance brings very big inconvenience to the higher operating position of dismounting frequency requirement especially.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, effectively ensureing the set lever of data delivery quality.
The technical problem that the utility model proposed is to solve like this: a kind of set lever, described set lever is mainly by handle be arranged at the locking wheel assembly that the handle two ends are symmetrical distribution respectively and connect and compose, and described locking wheel assembly staking or interference fit are connected in the two ends of handle.
Described locking wheel assembly is is mainly connected and composed by turning handle and two locator cards of fixing this turning handle, the termination, two ends and the middle part of described locator card offer through hole respectively, offer on the described turning handle with locator card on two corresponding through holes of through hole wherein, described turning handle is sticked between two locator cards and constitutes in the double wall, and passes in the corresponding through hole on locator card and the turning handle fixing by rivet.
Described locator card is circular arc, rectangle or other shape and structure, and the through hole that through hole that the locator card middle part is provided with and end, two ends are provided with is asymmetric setting.
Constitute cantilever mechanism apart from the area segments between the through hole at an end termination of middle part through hole far-end and this middle part on the described locator card.
End termination apart from middle part through hole far-end on the described locator card also is provided with roller.
The connecting portion that described handle two ends are connected with the locking wheel assembly offers the hole that is connected and fixed of fixing and locking wheel assembly, and described locking wheel assembly staking or interference fit are connected in this and are connected and fixed on the hole.
All parts seamed edges of the utility model all have fillet or chamfering in various degree, scratch the user when preventing to use.
In sum, the utility model is simple in structure, adopts roller cantilever type locking mode, and its friction type is rolling friction, has that reliable lock, the application of force are little, the advantage of good springiness.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model handle arrangement schematic diagram;
Among the figure: 1-handle, 2-turning handle, 3-cantilever, 4-roller, 5-locator card, 6-rivet, 7-are connected and fixed the hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of set lever, described set lever are mainly by handle 1 be arranged at the locking wheel assembly that handle 1 two ends are symmetrical distribution respectively and connect and compose, and described locking wheel assembly staking or interference fit are connected in the two ends of handle 1.
As shown in Figure 1, described locking wheel assembly is is mainly connected and composed by turning handle 2 and two locator cards 5 of fixing this turning handle 2, the termination, two ends and the middle part of described locator card 5 offer through hole respectively, offer on the described turning handle 2 with locator card 5 on two corresponding through holes of through hole wherein, described turning handle 2 is sticked between two locator cards 5 and constitutes in the double wall, and passes in the corresponding through hole on locator card 5 and the turning handle 2 fixing by rivet 6.Described locator card 5 is circular arc, rectangle or other shape and structure, the through hole that through hole that locator card 5 middle parts are provided with and end, two ends are provided with is asymmetric setting, after set lever is finished locking, moment is very little between locking mechanism place and the center of rotation, under the situation of the external force that has not applied the dismounting effect, lock quite reliable.Constitute cantilever 3 mechanisms apart from the area segments between the through hole at an end termination of middle part through hole far-end and this middle part on the described locator card 5, make set lever have good elasticity, reliable lock.End termination apart from middle part through hole far-end on the described locator card 5 also is provided with roller 4, and the friction type that produces when the rivet corresponding with it cooperates is rolling friction, has reduced to make it to finish the active force of locking function greatly.
As shown in Figure 2, what the connecting portion that described handle 1 two ends are connected with the locking wheel assembly offered the fixing and locking wheel assembly is connected and fixed hole 7, and described locking wheel assembly staking or interference fit are connected in this and are connected and fixed on the hole 7.
