Description

Technical Field

[0001] The utility model relates to the technical field of hook scales, in particular to a hook scale structure. Background Art

[0002] A hook scale is a device used to measure the weight of a hanging object. It is widely used in industrial and commercial fields. Common hook scales include single hook and double hook scales. Double hook scales are usually equipped with two hooks, which can hang heavy objects more stably and reduce measurement errors caused by swinging or unstable objects.

[0003] The number of hooks in a double-hook crane scale is fixed. For objects with larger areas or when there are many items to be weighed, the double-hook crane with fixed specifications cannot meet various requirements such as multi-directional balance and large capacity. Therefore, this solution provides a crane scale structure that can adaptively adjust the number of hooks. Utility Model Content

[0004] The utility model aims at least to solve the problem in the prior art that the size of the hook is fixed and cannot be expanded.

[0005] The present invention provides a hook scale structure, which is achieved by the following specific technical means: it includes a hook scale body, a double hook is fixed at the bottom of the vertical rod connecting the bottom side of the hook scale body and the weighing module in the hook scale body, an arc cavity is opened in the double hook, a connecting shaft is rotated in the middle of the arc cavity, a movable hook is fixed on the connecting shaft, and the movable hook is located in the arc cavity. When necessary, the two ends of the movable hook can be rotated out of the arc cavity by rotating the connecting shaft to form four groups of hooks.

[0006] Optimal technical solution 1: the connecting axis and the vertical rod are located on the same straight line.

[0007] Preferred technical solution 2: The lower outer wall of the vertical rod is provided with a thread, and a pressure ring is sleeved on the vertical rod. The pressure ring engages with the thread on the vertical rod through a threaded hole opened in the center, and its height on the vertical rod can be adjusted by rotating the pressure ring.

[0008] Preferred technical solution three: an angle locking assembly is connected between the connecting shaft and the vertical rod, and the angle locking assembly is used to limit the rotation angle of the connecting shaft.

[0009] Preferred technical solution four: the bottom end of the connecting shaft passes through the bottom wall of the double hooks, and the angle locking assembly includes an adjusting shaft that slides through the connecting shaft, and the top end of the adjusting shaft extends into a chamber opened in the vertical rod, and the top end of the adjusting shaft is fixedly connected to a limit plate slidably arranged in the chamber, and a supporting spring is connected between the limit plate and the bottom wall of the chamber, and at the same time, the connecting shaft can rotate around the adjusting shaft, and the limit plate is located at the top of the chamber under the push of the supporting spring. At this time, the pressure cap fixed at the bottom end of the adjusting shaft presses and contacts with the bottom end surface of the connecting shaft to limit the connecting shaft.

[0010] Preferred technical solution five: the outer diameter of the pressure ring is larger than the distance between the vertical rods of the double hooks and the movable hook ends.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. The number of working hooks can be increased when needed through the setting of movable hooks to increase the hook capacity, and hooks in different directions can also be added;

[0013] 2. The movable hook can be hidden in the arc-shaped cavity inside the double hook when not in use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 2 The structure of the hook scale includes a scale body 1, a double hook 3 is fixed at the bottom of the vertical rod 2 connecting the bottom side of the scale body 1 and the weighing module in the scale body 1, an arc cavity 31 is opened in the double hook 3, a connecting shaft 4 is rotated and penetrates the middle of the arc cavity 31, the connecting shaft 4 and the vertical rod 2 are located on the same straight line, and a movable hook 5 is arranged on the connecting shaft 4, the middle part of the movable hook 5 is fixedly sleeved with the connecting shaft 4, and the movable hook 5 is located in the arc cavity 31. When necessary, the two ends of the movable hook 5 can be rotated out of the arc cavity 31 by rotating the connecting shaft 4 to form four groups of hooks, which can be used to increase the hook capacity. At the same time, hooks in different directions can also be added, which can be more stable when hanging objects with relatively large length and width.

[0022] See also Figure 1-Figure 2 , hook scale structure, the lower outer wall of the vertical rod 2 is provided with a thread 21, and the vertical rod 2 is sleeved with a pressure ring 6, which engages with the thread 21 on the vertical rod 2 through the thread 21 hole opened in the center. The height of the pressure ring 6 on the vertical rod 2 can be adjusted by rotating the pressure ring 6. The outer diameter of the pressure ring 6 is larger than the distance between the ends of the double hook 3 and the movable hook 5 and the vertical rod 2, thereby realizing the anti-detachment shielding of the hook mouths of the double hook 3 and the movable hook 5.

[0023] See also Figure 3-Figure 4 , hook scale structure, an angle locking assembly 7 is connected between the connecting shaft 4 and the vertical rod 2, and the angle locking assembly 7 is used to limit the rotation angle of the connecting shaft 4; the bottom end of the connecting shaft 4 passes through the bottom wall of the double hook 3, and the angle locking assembly 7 includes an adjusting shaft 71 that slides through the connecting shaft 4, and the top end of the adjusting shaft 71 slides into the chamber 22 opened in the vertical rod 2, and the top end of the adjusting shaft 71 is fixedly connected to a limit plate 73 slidably arranged in the chamber 22, and a supporting spring 74 is connected between the limit plate 73 and the bottom wall of the chamber 22, and at the same time, the connecting shaft 4 can rotate around the adjusting shaft 71, and the limit plate 73 is located at the top of the chamber 22 under the pushing of the supporting spring 74. At this time, the pressure cap 76 fixed at the bottom end of the adjusting shaft 71 is pressed and contacted with the bottom end surface of the connecting shaft 4 to limit the connecting shaft 4;

[0024] At the same time, a connecting cap 75 is fixed to the bottom end of the connecting shaft 4, and the connecting cap 75 is connected to the inner cavity of the connecting shaft 4. A vertical groove 751 is opened on the inner wall of the connecting cap 75. A protrusion 72 is fixed to the side of the bottom end of the adjusting shaft 71. The protrusion 72 slides in the vertical groove 751. When the pressing cap 76 contacts the bottom end of the connecting cap 75, the protrusion 72 slides into the vertical groove 751. Since the adjusting shaft 71 can only undergo relative displacement up and down with the vertical rod 2, the adjusting shaft 71 cannot rotate, causing the connecting shaft 4 to be locked at this time. The movable hook 5 is in a crossed state with the double hook 3 and cannot be rotated, and at this time the connecting shaft 4 drives the movable hook 5 to be in a crossed state with the double hook 3, that is, at this time the end of the movable hook 5 extends out from the double hook 3; when it is necessary to rotate, it is necessary to pull down the pressing cap 76 so that the protrusion 72 is pulled out of the vertical groove 751 to release the limiting effect on the connecting shaft 4. At this time, the connecting shaft 4 can rotate freely. A finger ring 77 is fixed on the pressing cap 76. When in use, use one finger to insert into the finger ring 77 to pull down the adjusting shaft 71, and then the remaining fingers can cooperate to twist the connecting shaft 4.
