Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a handle butterfly valve comprises a valve body 2, wherein a wheel disc 1 and a handle 3 are arranged on the valve body 2; a notch 31 is formed in the handle 3, and a positioning pin 32 is arranged in the notch 31; the positioning pin 32 is inserted into the tooth slot on the wheel disc 1 by sliding the positioning pin 32 in the notch 31, so as to realize the positioning after the handle 3 rotates.

Through the mode, the handle 3 is matched with the positioning pin 32, the rotation of the handle 3 is realized by pulling the positioning pin 32 while the positioning of the handle is realized, and on the basis of realizing the basic functions of the rotation and the positioning of the handle 3, compared with the existing handle structure, the structure is compact, the handle 3 is not provided with an obvious convex part, the whole handle 3 is more flat and smooth in the aspect of external outline, and the space occupancy rate is lower.

Furthermore, a spring 30 is further arranged on one surface of the positioning pin 32, which is far away from the wheel disc 1, and the other end of the spring 30 is connected with the notch 31, so that the positioning pin 32 is urged to abut against a tooth pin on the wheel disc 1 by the spring 30. The positioning pin 32 is urged to abut against the tooth grooves of the wheel disc 1 by the spring 30 during the extension process, so that the positioning pin 32 is stably connected with the wheel disc 1.

On the basis of the scheme, the positioning pin 32 is connected with the pull rod 33, the pull rod 33 penetrates through the sliding groove 35 formed in the side surface of the handle 3 and then is movably connected with the positioning pin 32, and therefore the positioning pin 32 is driven to slide in the groove opening 31 by holding the pull rod 33 by hand, a user can conveniently control the positioning pin 32 to move outside, and the force of the user pulling the positioning pin 32 can be reduced.

In order to ensure that the handle 3 is smoothly and stably locked in the rotating process and the positioning pin 32 is reliably separated from the wheel disc 1, the chute 35 is further provided with a positioning groove 34, and after the pull rod 33 is pulled outwards, the positioning groove 34 is locked in the positioning groove, so that the sliding of the positioning pin 32 can be limited, and the reliable separation of the positioning pin 32 and the wheel disc 1 in the rotating process of the handle 3 is ensured; in addition, the number of the positioning grooves 34 may be two, and the specific arrangement manner is as follows: when one positioning groove 34 of the pull rod 33 is connected, the positioning pin 32 is ensured to be meshed with the tooth socket on the wheel disc 1, and when the pull rod 33 is connected with the other positioning groove 34, the positioning pin 32 is ensured to be completely separated from the tooth socket on the wheel disc 1. In particular, the positioning of the positioning slot 34 provides fewer parts for the fingers to grasp when turning the handle 3.

Because the back of the positioning pin 32 and one end of the notch 31 facing the wheel disc 1 are both used for fixing the fixing groove 36 of the spring 30, one end of the spring 30 is fixed in the fixing groove 36 on the positioning pin 32, and the other end of the spring 30 is fixed in the fixing groove 36 in the notch 31, the positions of the two ends of the spring 30 can be ensured to be stable, and the spring 30 can be prevented from popping out of the notch 31 due to the unstable end part of the spring 30; in addition, the maximum length of the spring 30 is larger than that of the notch 31 when the spring 30 is in a completely free state, so that the spring 30 is always in a pressed state, and the positioning pin 32 can be reliably ensured to be meshed with the tooth socket on the wheel disc 1.

Further, because the side surface of the positioning pin 32 is movably connected with the pull rod 33 through the internal threaded hole 37, the positioning pin 32 can be installed in the notch 31 first, and then the pull rod 33 is connected with the internal threaded hole 37, so that the positioning pin 32 and the notch 31 can be assembled conveniently, and the positioning pin 32 and the pull rod 33 can be assembled conveniently.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
