[0026] In order to make the technical problems, technical solutions and advantages of the utility model clearer, the following will be described in detail in combination with the drawings and specific embodiments.

[0027] As shown in the utility model discloses an embodiment provides a lock catch 20 structure, including connecting piece 10, lock catch 20 and bolt 30. Figs. 1-3 The connecting piece 10 is used to be half-enclosed on the closed section bar A from the side, and the closed section bar A is preferably a square tube. The connecting piece 10 includes oppositely arranged side plates 11 and a connecting plate 12 connecting the two side plates 11, and the connecting plate 12 is located on the same side of the two side plates 11. Locking windows 13 are formed on each side plate 11, and the inner side of the locking window 13 has internal teeth. The two rows of internal teeth are oppositely arranged along the height direction of the locking window 13. The lock catch 20 includes a locking piece 21 which can be arranged in the locking window 13. The locking piece 21 has external teeth which are engaged with the internal teeth. The height of the locking window 13 is greater than the height of the locking piece 21, so that the locking piece 21 can be installed at any position in the locking window 13. The aforementioned bolt 30 is used to fix the lock catch 20 in the locking window 13, and the bolt 30 is connected with the closed section bar A.

[0028] In the present application, the connecting piece 10 is used to connect horizontal members such as pipeline support hangers. The horizontal members are fixed on the vertical members through the connecting piece 10. When the connecting piece 10 is fixed on the vertical members, the closed section bar A is first punched according to the approximate position of installation, and then the connecting piece 10 is sleeved on the closed section bar A. The locking piece 21 is fixed in the locking window 13 and the side plate 11 is fixed on the closed section bar A through the bolt 30, realizing the connection of the horizontal members and the vertical members.

[0029] When it is necessary to adjust the levelness of the horizontal members, the height of the locking piece 21 in the locking window 13 can be adjusted.

[0030] In the present application, not only the fixation of the connecting piece 10 relative to the closed section bar A is realized, but also the height of the connecting piece 10 relative to the locking piece 21 can be adjusted by moving the position of the connecting piece 10, thereby realizing the fine adjustment of the height of the connecting piece 10.

[0031] Preferably, the locking window 13 and the locking piece 21 are both rectangular.

[0032] In the present embodiment, the external teeth are arranged on both sides of the locking piece 21 along the height of the locking piece 21. The locking piece 21 and the locking window 13 are engaged with each other through the teeth, thereby avoiding the relative sliding of the locking piece 21 and the connecting piece 10 in the vertical direction, thereby improving the safety of the present application. Moreover, the locking piece 21 and the locking window 13 both have multiple teeth, which can still maintain the relative fixation effect of the locking piece 21 and the connecting piece 10 in the case that one or more teeth are broken.

[0033] The aforementioned lock catch 20 further comprises a round gasket 22 fixedly attached to the locking piece 21, the round gasket 22 is concentrically arranged with the locking piece 21, and the center of the locking piece 21 and the round gasket 22 are both provided with a center through hole penetrating the locking piece 21 and the round gasket 22 along the thickness direction of the locking piece 21 and the round gasket 22. The thickness of the locking piece 21 is the same as the thickness of the side plate 11, the length and width of the locking piece 21 are both smaller than the diameter of the round gasket 22, and the diameter of the round gasket 22 is larger than the width of the locking window 13.

[0034] In the use of the lock catch 20 provided by the embodiment, the locking piece 21 is arranged in the locking window 13, and the locking piece 21 is closer to the closed profile A than the round gasket 22, and the bolt 30 is installed on the lock catch 20 by penetrating the center through hole of the locking piece 21 and the round gasket 22, wherein the locking piece 21 and the bolt 30 are used to limit the relative movement of the lock catch 20 and the connecting piece 10 in the vertical direction, and the round gasket 22 and the bolt 30 are used to limit the disengagement of the lock catch 20 and the connecting piece 10 in the horizontal direction.

[0035] Preferably, the locking piece 21 and the round gasket 22 are integrally formed.

[0036] In the present application, the lock catch assembly further comprises a nut 40, and the aforementioned bolt 30 is screwed with the nut 40 after penetrating the locking piece 21, the closed profile A and the other locking piece 21. The bolt 30 with a relatively long length penetrates the closed profile A along the width direction of the closed profile A, which facilitates the fixation of the bolt during the installation of the connecting piece 10.

[0037] Preferably, the connecting plate 12 is further provided with a receiving piece 14 for connecting a horizontal member, and the receiving piece 14 and the side plate 11 are respectively located on both sides of the connecting plate 12. Preferably, the connecting piece 10 is provided with a connecting hole.

[0038] The above is the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
