Description
Technical field
The utility model relates to a kind of T-shaped pin pin removal, particularly a kind of pin removal being applicable to dismounting T-shaped pin.
Background technology
In machine and parts, often use pin as location and the part be connected, general method for dismounting is: for the pin of through hole, is with instrument, pin to be beaten out, troublesome poeration, and labour intensity is large, and potential safety hazard is many; For the pin of band screw, a kind of band of usual use is pulled pin the pin removal of screw, by pulling pin, screw is screwed in the screw of pin, then pin removal axostylus axostyle is screwed into the nail other end of pulling pin, and uses sliding hammer to knock the large end of pin removal axostylus axostyle along the direction of extracting pin and can extract pin.But under certain conditions, restriction uses straight pin, and T-shaped pin need be used as shop bolt, and existing extracting tool cannot dismantle T-shaped pin.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of instrument extracting T-shaped pin, reduces labour intensity.
The purpose of this utility model is achieved through the following technical solutions: a kind of T-shaped pin pin removal, it comprises bolt, sliding hammer, nylon jacket and pin pulling head, bolt is made up of bolt head and screw rod, bolt head and screw rod one-body molded, pin pulling head is provided with internal thread, bolt and pin pulling head are threaded connection, side near pin pulling head on screw rod is installed with nylon jacket by interference fit, sliding hammer is provided with between nylon jacket and bolt head, pin pulling head is also provided with the first baffle plate and second baffle, and the shape of the first baffle plate is U-shaped.
Further, the shape of described second baffle is semicircle.
Further, the end face of the first described baffle plate is convex globoidal.
Further, described nylon jacket shape is round table-like, and the bottom surface of round platform is towards sliding hammer.
The beneficial effects of the utility model are:
1) T-shaped pin can be extracted by the impulsive force, utilizing sliding hammer to move generation;
2), the shape of the first baffle plate is set to U-shaped, and be convenient to the head blocking T-shaped pin, the shape of second baffle is semicircle, even if the external screw thread region of screw rod is long, screw rod is also unlikely to the region of stretching out second baffle place when being screwed into pin pulling head;
3), the end face of the first baffle plate is convex globoidal, be the design of plane compared to the end face of the first baffle plate, this design is more reasonable, when the end face of the first baffle plate encountered by T-shaped pin, the resistance run into will reduce greatly, is convenient to the first baffle plate and blocks T-shaped pin rapidly;
4), nylon jacket is set to round table-like one side and can prevents the hand holding nylon jacket from being injured by a crashing object, is conducive to extracting T-shaped pin rapidly under the effect of both hands on the other hand.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As Fig. 1, shown in Fig. 4, a kind of T-shaped pin 10 pin removal, it comprises bolt 2, sliding hammer 4, nylon jacket 5 and pin pulling head 6, bolt 2 is made up of bolt head 1 and screw rod 3, bolt head 1 is one-body molded with screw rod 3, pin pulling head 6 is provided with internal thread 9, bolt 2 and pin pulling head 6 are threaded connection, side near pin pulling head 6 on screw rod 3 is installed with nylon jacket 5 by interference fit, sliding hammer 4 is provided with between nylon jacket 5 and bolt head 1, pin pulling head 6 is also provided with the first baffle plate 8 and second baffle 7, as shown in Figure 2, the shape of the first baffle plate 8 is U-shaped, be convenient to the head blocking T-shaped pin 10, the shape of second baffle 7 is semicircle, even if the external screw thread region of screw rod is long, screw rod is also unlikely to the region of stretching out second baffle 7 place when being screwed into pin pulling head 6.
As shown in Figure 3, the end face of the first described baffle plate 8 is convex globoidal, is the design of plane compared to the end face of the first baffle plate 8, this design is more reasonable, when the end face of the first baffle plate 8 encountered by T-shaped pin 10, the resistance run into will reduce greatly, is convenient to the first baffle plate 8 and blocks T-shaped pin 10 rapidly.
As shown in Figure 5, described nylon jacket 5 shape is round table-like, and the bottom surface of round platform is towards sliding hammer 4.When pulling out T-shaped pin 10, one of operating personnel holds sliding hammer 4, and another holds nylon jacket 5, and two hands are simultaneously toward extracting the direction of T-shaped pin 10 firmly, sliding hammer 4 is beaten on bolt head 1, can extract T-shaped pin 10 through the above-mentioned action of one or many.Nylon jacket 5 is set to round table-like one side and can prevents the hand holding nylon jacket 5 from being injured by a crashing object, is conducive to extracting T-shaped pin 10 rapidly under the effect of both hands on the other hand.
The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
