Abstract

The utility model relates to a trigger switch, which is mainly composed of a trigger (4), a push rod (1) a main body (5), wherein a trigger iron frame (2) which has a box-shaped structure is connected with the trigger (4) to form a combined trigger, and an upper cover iron sheet (3) is arranged on an upper cover of the switch body (5) and connected with the combined trigger to form a structural entirety; the inner part of the structure of the push rod (1) is provided with a steel wire (6) in plastic mounting, and the steel wire is connected with the combined trigger. The utility model has the advantages of large structural strength and rigidity, firmness, high durability, strong breaking and locking ability, simple structure, and simple operation, maintenance and repair.

Description

Trigger

Technical field

The utility model relates to a kind of trigger, refers to that especially this switch has carried out important improvement to main member and the load-carrying member of commonly using trigger, makes it reach sturdy and durable and thorough improvement and resolves and unblank to decide function.

Background technology

Trigger is widely used in Machine Tool Electric Appliance on the current market, household electrical appliance, hardware ﹠ tools, electric tools etc. are located, and its function is similar substantially, but the product quality of different manufacturers differs greatly and integrates following functional defect: 1, the push rod of the type trigger all is to adopt the PA66 nylon material to make, this material plasticity is good, but to the variation sensitivity of weather, long-term use easily deforms, thereby cause switch motion dumb, accurate even inefficacy.2, the normal ABS plastic that adopts in the trigger ground of switch, this material stiffness and undercapacity usually make the disconnection lock function realize.3, the loam cake of switch also often adopts the PA66 nylon material, and this material stiffness and undercapacity can make the disconnection lock function realize equally.In sum, what influence the switch quality is these main members and load-carrying member, in order to ensure the quality of switch, must improve commonly using product, and make high-quality trigger electric switch.

Summary of the invention

According to background technology, the purpose of this utility model is to provide a kind of modified model trigger of commonly using the trigger functional defect that overcomes.Employing improves pusher structure, and the way that adds steel wire in the push rod moulding is strengthened its strength and stiffness, makes it no longer be subjected to climatic influences.

Strengthen with brandreth in the switch trigger, the switch loam cake is strengthened with iron plate, and the new structural member of formulating with these corrective measures can make switch become permanently effective work, and is sturdy and durable, disconnects the very strong trigger of lock function.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of trigger, mainly by trigger 4, push rod 1 and main body 5 are formed, wherein: trigger brandreth 2 is a box structure, and the trigger 4 of packing into connects to form the combination trigger, and loam cake iron plate 3 is formed switch main body with the loam cake of main body 5, and is connected to become a structural entity with the combination trigger, the inside configuration of push rod 1 is moulded and is adorned a steel wire 6 and become composite construction, and is connected with the combination trigger.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, in the utility model trigger configuration liner the trigger brandreth strength and stiffness of structure are increased greatly, support connecting piece as trigger and main body, adopt the loam cake iron plate to increase strength and stiffness equally, thoroughly improved the problem that trigger disconnects the lock function difference of commonly using.The utlity model has and stand long-term use, disconnect the strong effect of locking ability.

2, the push rod of the utility model trigger is moulded the structure of holding in the mouth steel wire in being, strength and stiffness are big, makes operation accurately, and is sturdy and durable.

3, the utility model is simple in structure, and is cheap, and working service is repaired simple and easy.

Embodiment

By Figure 1A to Fig. 3 illustrate, a kind of trigger electric switch, mainly by trigger 4, push rod 1 and main body 5 are formed, and wherein: trigger brandreth 2 is a box structure, and the trigger 4 of packing into connects to form the combination trigger, loam cake iron plate 3 is formed switch main body with the loam cake of main body 5, and being connected to become a structural entity with the combination trigger, the inside configuration of push rod 1 is moulded and is adorned a steel wire 6 and become composite construction, and is connected with the combination trigger.

As seen from the figure, trigger brandreth 2 is a box structure, and its strength and stiffness are enough big, adds a loam cake iron plate 3 again simultaneously on switch, has increased support rigidity, causes the disconnection lock function of trigger very strong.

By Fig. 4 the structure of push rod 1 is shown, its main structure body is by the nylon material manufacturing, and moulds rank one steel wire 6 in inside configuration, the strength and stiffness of push rod are greatly increased, nor be subjected to climatic influences again, can make switch be fit to long-term work, and can keep flexibility and do not lose efficacy.

Claims

1, a kind of trigger, mainly by trigger (4), push rod (1) and main body (5) are formed, it is characterized in that: trigger brandreth (2) is a box structure, and the trigger of packing into (4) connects to form the combination trigger, and loam cake iron plate (3) is formed switch main body with the loam cake of main body (5), and is connected to become a structural entity with the combination trigger, the inside configuration of push rod (1) is moulded and is adorned a steel wire (6) and become composite construction, and is connected with the combination trigger.
