Detailed Description

In order to better understand the above technical solutions, the following detailed description of the technical solutions of the embodiments of the present application is made by using the accompanying drawings and the specific embodiments, and it should be understood that the specific features of the embodiments of the present application are detailed descriptions of the technical solutions of the embodiments of the present application, and not limit the technical solutions of the present application, and the technical features of the embodiments of the present application may be combined with each other without conflict.

In view of this, according to an embodiment of the present application, there is provided a lock for locking a disc-type valve hand wheel, including a first column 1, a second column 2, a first beam 3, a second beam 4, and a locking belt 5; one end of the first upright 1 is connected with one end of the first cross beam 3; one end of the second upright post 2 is connected with one end of the second cross beam 4; the first cross beam 3 and the second cross beam 4 are connected in a sliding manner in the length direction of the first cross beam 3 and the second cross beam 4; one end of the locking belt 5 is rotatably connected with one end of the first upright 1 far away from the first cross beam 3; the portion of the locking strap 5 remote from the first upright 1 can be locked or unlocked with the end of the second upright 2 remote from the second cross member 4.

In a specific embodiment, as shown in fig. 1, the first upright 1 and the first beam 3 are at right angles, the second upright 2 and the second beam 4 are also at right angles, and after the first beam 3 is connected with the second beam 4, the first upright 1 and the second upright 2 are parallel to each other, that is, the whole lockset is rectangular. The first cross beam 3 is in sliding connection with the second cross beam 4, and the width of the lockset can be adjusted, so that the lockset can adapt to disc-type valves with different sizes. The locking belt 5 is rotatably connected with the first upright 1, so that the locking belt 5 can rotate to be overlapped with the first upright 1, the first upright 1 can conveniently penetrate through a handle gap of the disc-type valve hand wheel 7 and various other structures, and the lock is more convenient to carry. In addition, in order to reduce the weight and cost of the lock, on the basis of ensuring the strength of the lock, the first upright 1, the second upright 2, the first cross beam 3 and the second cross beam 4 may be hollow pipes.

In the actual process of locking the disc valve, the locking belt 5 is first rotated to overlap the first upright 1, and then the first upright 1 and the second upright 2 are respectively passed through two different handle gaps of the disc valve hand wheel 7 and respectively passed through two sides of the fixture 8; the first cross beam 3 and the second cross beam 4 are adjusted to enable the width of the lockset to be matched with the sizes of the disc-type valve hand wheel 7 and the fixed object 8; the locking belt 5 is rotated so that the part of the locking belt 5 away from the first upright 1 is close to the second upright 2, the locking belt 5 is positioned on the side of the fixture 8 away from the disc-type valve hand wheel 7, and then the locking belt 5 and the second upright 2 are tensioned and locked together. As shown in fig. 2, the lock according to the present application can lock the disc-type valve hand wheel 7 and the fixture 8 together, thereby locking the disc-type valve hand wheel 7 from rotation. The fixing object 8 may be a fixed pipe or a disc valve bracket, etc. which is a fixing structure convenient for use.

Preferably, in a specific embodiment, as shown in fig. 1, the second beam 4 is inserted into the first beam 3 and can slide along the length direction of the first beam 3. This setting results in the lock having a minimum width that is the length of the first beam 3 and a maximum width that is slightly less than the sum of the lengths of the first beam 3 and the second beam 4. In practical operation, the width is designed to be 8-28cm, and the length of the first upright 1 and the second upright 2 is 30cm, which is enough to meet the requirement of locking disc valves with various sizes.

Further, in one embodiment, the first beam 3 and the second beam 4 are provided with a disengagement preventing member for limiting the second beam 4 in the length direction of the first beam 3 and the second beam 4.

Preferably, in a specific embodiment, the anti-disengaging member includes a first limiting plate 31 and a second limiting plate 41; the first limiting piece 31 is arranged inside a port of one end of the first cross beam 3, which is far away from the first upright 1; the second limiting piece 41 is disposed at one end of the second cross beam 4 away from the second upright 2, and is used for abutting against the first limiting piece 31. The second cross beam 4 provided with the second limiting piece 41 can slide inside the first cross beam 3, and when one end of the second cross beam 4, which is far away from the second upright 2, slides to the port of the first cross beam 3, which is far away from one end of the first upright 1, the first limiting piece 31 is abutted against the second limiting piece 41, so that the second cross beam 4 is prevented from sliding in a direction away from the first cross beam 3, and the second cross beam 4 cannot be separated from the first cross beam 3, so that the problem of lock separation when carrying and installing locks is avoided. In a specific operation, the second limiting piece 41 may be a protrusion slightly larger than the pipe diameter of the second cross member 4.

Further, in one embodiment, the first beam 3 and the second beam 4 are connected by damping, that is, friction force between the inner wall of the first beam 3 and the outer wall of the second beam 4 is increased, so that sliding connection between the first beam 3 and the second beam 4 is more stable, and after the lock is adjusted and locked, the first beam 3 and the second beam 4 cannot slide easily due to external force, so that the lock becomes loose.

The damping connection here may be either a hard connection or a soft connection. The hard connection is that the inner wall of the first beam 3 is tightly contacted with the outer wall of the second beam 4 to increase the friction force between the two, as described in the 29 th paragraph of the specification of CN219668748U, "the outer wall of the storage cylinder 2 is provided with a vertical operation slot 11, the operation end block 12 is disposed outside the storage cylinder 2 through the operation slot 11, and the operation end block 12 is in damping connection with the operation slot 11. In the soft connection, that is, a damping member for increasing friction force is disposed between the inner wall of the first beam 3 and the outer wall of the second beam 4, for example, a material with damping performance such as rubber, silica gel, etc., for example, a "soft connection member described in paragraph 31 of the specification of CN116649870a may include a damping member 500, and at least one of the housing 100 and the lever 200 is disposed between the corresponding dial 300 or pointer 400, and the damping member 500 may be made of a material with damping performance such as rubber, silica gel, etc. The damping member 500 can be in abutting connection with the associated dial 300 or pointer 400. The damping member 500 is fixed by, but not limited to, clamping, bonding, and crimping. In an embodiment of the present application, the damping member may be connected to an inner wall of the first beam 3, and a surface of the damping member away from the inner wall of the first beam 3 abuts against an outer wall of the second beam 4.

Further, in one embodiment, the connector 6 is further included; a lock hole 51 is arranged on the locking belt 5, and a connecting hole 21 is arranged at one end of the second upright 2 far away from the second cross beam 4; the connecting piece 6 passes through the locking hole 51 and the connecting hole 21 to connect the locking strap 5 and the second upright 2.

Further, in one embodiment, as shown in fig. 1, the lock holes 51 are plural, and the plural lock holes 51 are arranged along the length direction of the locking belt 5. This arrangement allows the locking strap 5 to be movably connected between the second upright 2 at different lengths, thereby ensuring that the lock is adaptable to different sizes. In a specific operation, the number of the lock holes 51 and the intervals between a plurality of the lock holes 51 may be set according to actual needs, so as to ensure that the lock can realize the locking function under different conditions.

Further, in one embodiment, the locking belt 5 is made of soft material, and the length of the locking belt 5 is greater than the maximum length formed by the first beam 3 and the second beam 4. If the locking belt 5 is made of a hard material, the contact surface between the locking belt 5 and the fixed object 8 is in linear contact, the friction force between hard-touch and hard-connection is small, and displacement is easy to occur under the condition of encountering external force, so that the lockset becomes loose. The flexible locking belt 5 not only can penetrate through various complex structures, but also can fully wrap the outer surface of the fixed object 8 so that the contact area between the locking belt 5 and the fixed object 8 is greatly increased, and meanwhile, the friction force between the surface of the flexible material and the surface of the fixed object 8 is utilized, so that the locking is firmer.

Preferably, in a specific embodiment, the locking belt 5 is made of canvas material, the periphery of the locking hole 51 is made of metal material, and in actual operation, the locking hole 51 can be increased at any time according to needs. In addition, the locking belt 5 may be made of other soft and firm materials.

Preferably, in a specific embodiment, the connecting member 6 comprises a padlock, and may be other means capable of connecting the locking strap 5 and the second upright 2 and locking against falling off.
