AI Technical Summary
When the traditional lock structure is subjected to a large external force perpendicular to the direction of the clamping rod, the connection is not stable enough, which easily causes the clamping rod to fall out of the clamping ring.
Using a lift-type locking structure, a secure connection is achieved through two vertical first support rods and two movable second support rods, and a slot and position connection of the first connecting block and the second connecting block is achieved by combining the rotating shaft and the sliding groove design.
When subjected to a large horizontal direction force, the connection between the clamp block and the clamp slot is still stable, and the limiting plate maintains the horizontal state of the second support rod, improving the stability and operational convenience of the lock.

Abstract
Description
Technical Field
[0001] The present application relates to the field of lock buckle structures, and in particular to a pull-type lock buckle. Background Art
[0002] In order to provide a larger usable area, campervans generally rotate some side panels to connect with the bottom panel. When the side panels are rotated to be flush with the bottom panel, the usable area of the campervan can be expanded. When the campervan is stored, the side panels are rotated to a vertical state and fixed by a locking structure. The locking structure generally consists of a movable part and a fixed part. When in use, the connection and disconnection between multiple side panels are achieved by combining and separating the movable part and the fixed part.
[0003] The traditional locking structure has an arc-shaped fixed part and a cylindrical clamping rod as the movable part. The connection is achieved by inserting the clamping rod into the clamping ring. When this connection method is subjected to a large external force perpendicular to the direction of the clamping rod, the clamping rod is easy to fall out of the clamping ring, and the connection is not stable enough.

[0037] The following is combined with Figure 1-5 This application is described in further detail.
[0038] The embodiment of the present application discloses a pull-type lock. Figure 1 as well as Figure 2 A lifting lock includes two first support rods 1 and two second support rods 2. The two first support rods 1 are vertically arranged and spaced apart from each other. The two second support rods 2 are movably connected to the lower end of the first support rod 1 through a connecting block 3. The connecting block 3 includes a vertical first connecting plate 31 and a horizontal second connecting plate 32. The first connecting plate 31 is used to be fixedly connected to the first support rod 1, and the second connecting plate 32 is fixedly connected to the first connecting plate 31. A rotating shaft 33 is fixed to the end of the second connecting plate 32. The side wall of the second support rod 2 is provided with a sliding groove 21 arranged along the length direction of the second support rod 2, and the rotating shaft 33 is slidably connected to the sliding groove 21 along the length direction of the sliding groove 21.
[0039] Reference Figure 3 、 Figure 4 as well as Figure 5A first connecting block 11 is installed on the side of the first support rod 1 facing the second support rod 2. The first connecting block 11 is a hollow structure, and a card slot 111 is opened at the upper end of the first connecting block 11. A second connecting block 22 is installed on the side of the second support rod 2 facing the first support rod 1. The second connecting block 22 is a hollow structure, and a card block 221 is fixed to the lower end of the second connecting block 22. When the card block 221 is inserted into the card slot 111, the pull-up lock is in a locked state.
[0040] Reference Figure 4 as well as Figure 5 , the inner side walls of the first connecting block 11 and the second connecting block 22 are fixed with a limiting cylinder 4, and a fixing member 5 for respectively installing the first connecting block 11 and the second connecting block 22 on the first support rod 1 and the second support rod 2 is installed in the limiting cylinder 4. The fixing member 5 includes a fixing rod 51 and two fixing plates 52. When installing the first connecting block 11, the operator passes the fixing rod 51 with a fixing plate 52 at one end through the limiting cylinder 4, the first connecting block 11 and the first support rod 1, and then uses a tool to extend the fixing rod 51 out of one end of the first support rod 1 and flatten it to form another fixing plate 52. The fixing plate 52 is locked with the first support rod 1, thereby locking the first connecting block 1 1 is connected and fixed with the first support rod 1. When installing the second connecting block 22, the operator passes the fixing rod 51 with a fixing plate 52 at one end through the limiting cylinder 4, the second connecting block 22 and the second support rod 2, and then uses a tool to extend the fixing rod 51 out of the end of the second support rod 2 and flatten it to form another fixing plate 52. The fixing plate 52 is locked with the second support rod 2, thereby connecting and fixing the second connecting block 22 to the second support rod 2. A limiting groove 41 is provided on the end of the first connecting block 11 away from the first connecting rod and the end of the second connecting block 22 away from the first connecting rod. The fixing plate 52 is arranged in the limiting groove 41 to reduce the situation where the limiting plate 34 is hooked onto people or objects.
[0041] Reference Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 The two second support rods 2 are connected by a handle rod 6, and the handle rod 6 drives the two second support rods 2 to rotate at the same time. The connection between the handle rod 6 and the second support rod 2 is chamfered to protect the operator.
[0042] Reference Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5When the second support rod 2 moves, the rotating shaft 33 moves along the length direction of the sliding groove 21 from the end of the sliding groove 21 close to the second connecting block 22 to the end of the sliding groove 21 away from the second connecting block 22. When the rotating shaft 33 moves in the sliding groove 21, the lifting function of the second support rod 2 is realized. The operator rotates the second support rod 2 to a state parallel to the first support rod 1. At this time, the distance between the block 221 and the rotating shaft 33 is greater than the distance between the block 221 and the rotating shaft 33. Then press the second support rod 2. When the second support rod 2 moves, the rotating shaft 33 moves along the length direction of the sliding groove 21 from the sliding block 22 to the end of the sliding groove 21 away from the second connecting block 22. When the second support rod 2 moves, the rotating shaft 33 moves along the length direction of the sliding groove 21 from the end of the sliding groove 21 close to the second connecting block 22 to the end of the sliding groove 21 away from the second connecting block 22.
