Abstract

The utility model discloses a triangular core key which comprises a key head, a first key rod, a second key rod, a pin and a handle, wherein a groove is formed in the bottom of the key head, one end of the first key rod is matched with the groove in shape and embedded into the groove to be fixed through the pin, the second key rod is stored in the other end of the first key rod, and one end of the second key rod is fixedly connected with the handle. The triangular core key has the advantages that rotation can be achieved between the key rod and the key head, the key moves flexibly, and space required by the key rod during operation is reduced. Furthermore, the key rod can perform telescopic motion, the length can be regulated at will according to needs, and the triangular core key can be used in the small regulation region and the farther region. Installing, debugging and maintaining are convenient and fast, work efficiency is effectively increased, protective properties and safety of products are ensured, and potential safety hazards of products during operation are eliminated.

Description

Triangle core key

Technical field

The utility model relates to a kind of triangle core key; Particularly relate to wind-powered electricity generation field, open the triangle core key of pitch-controlled system control cabinet.

Background technology

A plurality of control cabinets of pitch-controlled system, motor are installed in the wheel hub of wind-powered electricity generation complete machine, and due to the limited space in complete machine wheel hub, therefore, the operating space between each control cabinet is narrow and small, and there will be the phenomenon of blocking mutually mutually between control cabinet; Yet, when installation, debugging and service equipment, can frequently open the door lock of control cabinet; The column structure that the key bit of existing triangle core key and key bar are formed as one, when running into the door lock being blocked, cannot normally open control cabinet, for installing, debug, safeguarding, brought very large difficulty, cannot normally closed control cabinet, will bring great potential safety hazard.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of flexibility strong triangle core key.

The technical scheme that the utility model adopts is: a kind of triangle core key, comprises key bit, the first key bar, the second key bar, bearing pin and handle; The base of described key bit is formed with groove, and one end shape and the groove of described the first key bar are suitable, and embeds in groove and be fixed by bearing pin; The other end of described the first key bar has been taken in the second key bar, and one end of described the second key bar is fixedly connected with handle.

Described the first key bar can rotate centered by bearing pin; Described the first key bar is hollow structure, is set with the second key bar.

The beneficial effects of the utility model are: owing to can rotating between key bar and key bit, and the needed space of key bar when key has reduced operation flexibly; In addition, because key bar can stretch, make length free adjustment as required, be also conducive to regulate and control territory, little You compare far field, region and use; Make to install, debug and safeguard more convenient, effectively improved operating efficiency, guaranteed barrier propterty and the security performance of product, eliminated the potential safety hazard of product in running.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

As shown in Figure 1 to Figure 3, the utility model triangle core key, comprises, key bit 1, the first key bar 2, the second key bar 3, bearing pin 4 and handle 5; The base of described key bit 1 is formed with groove, and one end shape and the groove of described the first key bar 2 are suitable, and embeds in groove and be fixed by bearing pin 4, and described the first key bar 2 can rotate centered by bearing pin; Described the first key bar 2 is hollow structure, is set with the second key bar 3, and one end of described the second key bar 3 is fixedly connected with handle 5.

The utility model triangle core key, when the control cabinet of operation normal condition, can complete the repertoire to the unlatching of control cabinet and locking without extending key bar and rotating the first key bar; When the operation control box of narrow region, need be by the first key bar along bearing pin half-twist, the two becomes plumbness the first key bar and key bit base, parallel with control cabinet door-plate, hold handle, from door-plate side, the lock core that key bit is inserted into door lock is opened and locking control cabinet; Operation control box in narrow region and when distant, need be by the first key bar along bearing pin half-twist, the two becomes plumbness the first key bar and key bit base, parallel with control cabinet door-plate, the first key bar is pulled out from the second key bar, hold handle from door-plate side, the lock core that key bit is inserted into door lock is opened and locking control cabinet.

The utility model is owing to can rotating between key bar and key bit, the needed space of key bar when key has reduced operation flexibly; In addition, because key bar can stretch, make length free adjustment as required, also being conducive to zonule far away uses, make to install, debug and safeguard more convenient, effectively improve operating efficiency, guaranteed barrier propterty and the security performance of product, eliminated the potential safety hazard of product in running.
