Example 1:
as shown in fig. 1-10, the utility model discloses a distance lock catch, which comprises a lock rod 3 and two lock sleeves 2, wherein the inside of each lock sleeve 2 is of a hollow columnar structure, positioning ribs 6 are arranged on the circumferential outer surface of the lock rod 3, the positioning ribs 6 are axially arranged along the lock rod 3, two distance grooves 7 are arranged on the positioning ribs 6 at intervals, positioning protrusions 8 are arranged on the inner wall of each lock sleeve 2, the positioning protrusions 8 are in fit and clamping connection with the distance grooves 7, and the lock sleeves 2 are used for being fixed on a display screen box body 1.
Wherein the length of the distance groove 7 on the positioning rib 6 is equal to the length of the positioning protrusion 8 on the lock sleeve 2.
In other embodiments, the number of the positioning ribs 6 may be one, at least one channel for the positioning ribs 6 to pass through is needed inside the lock sleeve 2, and positioning protrusions 8 are needed to be arranged on the side wall of the channel, the positioning ribs 6 pass through the channels on the sides of the positioning protrusions 8, and when the positioning protrusions 8 correspond to the distance grooves 7, the lock rod 3 is rotated, so that the positioning protrusions 8 are clamped in the distance grooves 7, and connection between the lock sleeve 2 and the lock rod 3 is achieved. The lock sleeve 2 is provided with a plurality of holes and is fixed on the display screen box body 1 through bolts. After the lock sleeve 2 is arranged on the display screen box body 1, the distance difference between the sum of the distances between the positioning protrusions 8 on the lock sleeve 2 on the corresponding display screen box body 1 and the edges of the display screen box body 1 and the distance between the two adjacent distance grooves 7 on the lock rod 3 is the distance between the adjacent display screens. Since the lock sleeve 2 is fixed on the display screen, the distance between the positioning bulge 8 and the edge of the display screen is determined, and the distance between the distance grooves 7 on the lock rod 3 is also determined, the distance between the adjacent display screen boxes 1 is determined after each assembly, and the distance assembly of the display screen boxes 1 is realized.
Of course, the distance groove 7 on the lock lever 3 may pass through the positioning rib 6, or may not pass through the positioning rib 6.
Wherein the axial length of the positioning protrusion 8 should be equal to the axial length of the positioning groove, and the positioning protrusion 8 and the positioning groove cannot be in clearance fit.
The number of the positioning ribs 6 on the lock rod 3 is more than 2, the distance grooves 7 on the positioning ribs 6 are positioned on two circumferences of the lock rod 3 in the axial direction, positioning protrusions 8 with the same number as the positioning ribs 6 are arranged on the inner wall of the lock sleeve 2, and channels for the positioning ribs 6 to pass through are formed between the adjacent positioning protrusions 8. Wherein more than 2 of them comprise 2. In this embodiment, the number of the positioning ribs 6 on the lock rod 3 is 4, the intervals between the positioning ribs 6 are the same, 4 positioning protrusions 8 are also arranged on the inner wall of the lock sleeve 2 at equal intervals, and the positioning ribs 6 pass through channels formed between adjacent positioning protrusions 8.
A handle 9 is provided at one end of the lock lever 3. The handle 9 on the lock rod 3 can facilitate the rotation of the lock rod 3 to realize the cooperation of the distance groove 7 and the positioning protrusion 8.
An axial limit groove 12 is formed in the lock rod 3 along the axial position, two circumferential limit grooves 13 are formed in the axial limit groove 12 in an extending mode at intervals, a limit pin 5 is arranged on the lock sleeve 2 or the display screen box body 1, and the end portion of the limit pin 5 is located in the axial limit groove 12 or the circumferential limit groove 13.
