Description

Technical Field

[0001] The utility model belongs to the technical field of tape measure hooks, in particular to a rotating tape measure hook. Background Art

[0002] The existing tape measure hook is generally made of metal material and is L-shaped. For example, the Chinese invention patent application with application number 200910095552.4 discloses a reinforced tape measure hook, the horizontal part of which is riveted to the end of the tape by rivets, and the vertical part is used to hook and pull the measured object. When using the tape measure to measure the length of an object, the vertical part of the tape measure hook is hooked to one end of the measured object, and then the tape measure is pulled to gradually pull out the tape wound on the roller.

[0003] The existing structure of the ruler hook will have the following technical problems in actual use: when the tape measure is actually used, it not only has the function of measuring the length of an object, but also has the function of drawing lines on the surface of an object for operators in certain fields, such as carpenters, that is, using one side edge of the ruler tape as a reference line to draw a straight line. In the process of drawing a straight line, the vertical part of the existing ruler hook will abut against the surface of the object to cause interference, thereby forming a triangular space between the vertical part, the surface of the object and the ruler tape, so that one side edge of the ruler tape close to the ruler hook is too far away from the surface of the object, which makes it inconvenient for the operator to draw lines and the accuracy of the drawn straight line is poor. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the present application provides a rotating ruler hook, the hook head of which can be rotated and can be kept in a vertical and horizontal state, so as to hook an object for measurement in a vertical state and facilitate line drawing in a horizontal state.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rotating ruler hook comprises a connecting plate arranged at the end of a ruler tape, a rotating shaft is arranged on the connecting plate along the width direction thereof, and a hook head is rotatably connected to the connecting plate via the rotating shaft; the hook head comprises a longitudinal portion, a transverse portion fixedly connected to the longitudinal portion, and a limiting portion arranged at the upper end of the longitudinal portion; the transverse portion is rotatably sleeved on the rotating shaft, and the longitudinal portion can be rotated to a vertical state and a horizontal state respectively with the rotating shaft as an axis, and when the longitudinal portion is in a vertical state, the limiting portion abuts against the connecting plate and the longitudinal portion cannot rotate clockwise with the rotating shaft as an axis.

[0007] Preferably, a fixing plate is provided on the connecting plate, the rotating shaft is fixedly inserted in the fixing plate, two fixing holes are opened on the fixing plate, and a fixing protrusion is provided on the transverse part. When the fixing protrusion is respectively clamped in the two fixing holes, the longitudinal part is respectively in a vertical state and a horizontal state.

[0008] Preferably, a hook plate is vertically arranged at the end of the connecting plate close to the hook head.

[0009] Preferably, the connecting plate includes a first connecting plate fixedly connected to the ruler tape, a transition plate fixedly connected to the first connecting plate and arranged obliquely, and a second connecting plate horizontally fixedly connected to the upper end surface of the transition plate, and the fixed plates are arranged on both sides of the second connecting plate.

[0010] Preferably, reinforcing ribs are provided between the transition plate and the second connecting plate.

[0011] Preferably, the limiting portion includes a limiting plate horizontally fixedly connected to the upper end surface of the longitudinal portion. When the longitudinal portion is in a vertical state, the upper end surface of the limiting plate abuts against the lower end surface of the second connecting plate. When the longitudinal portion is in a horizontal state, the limiting plate is detached from the second connecting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can realize the conversion of the hook head between the vertical state and the horizontal state by rotating the hook head to the connecting plate. Compared with the existing tape measure hook with a fixed hook head, the hook head of the utility model can hook the object to measure the length in the vertical state and avoid the interference between the hook head and the surface of the object in the horizontal state so as to draw lines on the surface of the object; in addition, the utility model can limit the vertical state and the horizontal state of the hook head and improve the overall connection strength of the hook by setting a fixing hole, a fixing protrusion and a limiting part. By setting a hook plate, the hook plate can be used to hook the inner cavity of the object, thereby increasing the application range of the hook. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. The description of the vertical and horizontal states in the embodiments of this specification only refers to the relative positional relationship of the corresponding components. In the embodiments of this specification, the relative positional relationship can be combined with the attached drawings. Figure 7 , 8 The longitudinal portion of the middle hook head is respectively in a vertical state and a horizontal state. Of course, when the utility model is used for actual measurement, the vertical and horizontal states may be different due to the different structures of the measured objects and the measuring angles. Example

[0025] See also Figures 1 to 6 As shown, a rotary ruler hook comprises a connecting plate 1 mounted on one end of a ruler tape 4, a rotating shaft 2 arranged on the connecting plate 1 and a hook head 3 rotatably connected to the rotating shaft 2.

[0026] See also Figure 2 ,3 As shown, the connecting plate 1 includes a first connecting plate 11, a transition plate 12, a second connecting plate 13 and a fixing plate 14. Among them, two waist-shaped connecting through holes 111 are opened on the first connecting plate 11 along its length, and the connecting rivets 112 are penetrated in the connecting through holes 111 and fixedly penetrated on the tape 4, so that the connecting plate 1 is fixedly installed on the tape 4. Of course, the first connecting plate 11 can move along its length direction, and the movement can offset the difference caused by the hook head 3 hooking or holding the object for measurement, which is the prior art and will not be repeated here.

[0027] The transition plate 12 is arranged obliquely and one end thereof is integrally formed with the first connecting plate 11, and the other end thereof is integrally formed with the second connecting plate 13. In order to improve the connection strength between the transition plate 12 and the second connecting plate 13, a reinforcing rib 15 is integrally formed and fixedly connected to the transition plate 12 and the second connecting plate 13 at the inner connection of the transition plate 12 and the second connecting plate 13. Two fixing plates 14 are relatively parallel and vertically arranged and are integrally formed and fixedly connected to both sides of the second connecting plate 13, respectively, so that the transition plate 12, the fixing plate 14, and the second connecting plate 13 enclose a receiving cavity for accommodating the rotating shaft 2 and the hook head 3.

[0028] In addition, coaxial rotation holes 141 are respectively provided in the middle of the two fixing plates 14, and the rotating shaft 2 can be fixedly inserted into the rotation holes 141. Two fixing holes 142 are provided on each fixing plate 14. In this embodiment, the axes of the two fixing holes 142 are in a horizontal state and the distance between the axes of the two fixing holes 142 and the axis of the rotation hole 141 is the same.

[0029] A hook plate 16 is vertically arranged on the end of the second connecting plate 13 near the hook head 3, and the hook plate 16 is integrally formed with the second connecting plate 13. In this embodiment, by arranging the hook plate 16, the inner cavity of the object to be measured can be hooked, thereby facilitating measurement and reading.

[0030] See attached Figure 4 , 5 As shown, the hook head 3 includes a vertically arranged longitudinal portion 31 in a convex plate-like structure, a vertically arranged transverse portion 32 of a plate-like structure on both sides of the upper portion of the longitudinal portion 31 and fixedly connected along the length direction of the first connecting plate 11, and a stopper 33 arranged at the upper end of the longitudinal portion 31. A coaxial hook head through hole 321 is opened in the middle of the two transverse portions 32, thereby, it can be seen Figure 1 As shown, the shaft 2 is inserted into the hook head through hole 321 and the rotation through hole 141. In this embodiment, the shaft 2 can be a rivet structure, that is, the shaft 2 is riveted on the transverse portion 32, and the hook head 3 can rotate relative to the fixed plate 14 with the shaft 2 as the axis.

[0031] In this embodiment, the longitudinal portion 31 of the hook head 3 can be rotated to a vertical position. Figure 7As shown, it can also be rotated counterclockwise to a horizontal state as shown Figure 8 In order to make the hook head 3 shake when it is in the two states, fixing protrusions 322 are provided on the opposite end faces of the two transverse parts 32. The fixing protrusions 322 can be integrally formed with the transverse parts 32 and can be hemispherical. The diameter of the hemispherical fixing protrusions 322 is the same as the diameter of the fixing holes 142, so that when the longitudinal part 31 is in the vertical or horizontal state, the fixing protrusions 322 are respectively clamped in different fixing holes 142.

[0032] Furthermore, when the object to be measured is longer, the length of the tape 4 pulled out is longer and the spring force exerted on the hook head 3 is also greater. In order to prevent the fixing protrusion 322 from escaping from the fixing hole 142 due to excessive force when the longitudinal portion 31 is in a vertical state, so that the longitudinal portion 31 rotates clockwise, thereby causing measurement failure, a limiting portion 33 needs to be provided on the longitudinal portion 31. The limiting portion 33 can have various forms as long as it can limit the longitudinal portion 31 when it is in a vertical state to avoid its clockwise rotation. For example, in a certain embodiment, the limiting portion 33 can be directly formed by extending from the longitudinal portion 31 to its upper part to exceed the lower end face of the second connecting plate 13. At this time, the inner end face of the limiting portion 33 abuts against the outer end face of the hook plate 16. In this embodiment, the limiting portion 33 is a limiting plate fixedly connected horizontally to the upper end surface of the longitudinal portion 31. The limiting plate and the longitudinal portion 31 are integrally formed and arranged. When the longitudinal portion 31 is in a vertical state, the limiting plate is inserted into the above-mentioned accommodating cavity and its upper end surface abuts against the lower end surface of the second connecting plate 13. When the longitudinal portion 31 is in a horizontal state, the limiting plate is separated from the second connecting plate 13 and the accommodating cavity. Figure 8 shown.

[0033] The working process of the embodiment of the utility model is as follows:

[0034] like Figure 7 As shown, when the length of an object needs to be measured, the longitudinal portion 31 is in a vertical state, at this time, the fixing protrusion 322 on the transverse portion 32 is clamped in the fixing hole 142 on the right side of the fixing plate 14, the limiting portion 33 is penetrated in the accommodating cavity and its upper end surface is in contact with the lower end surface of the second connecting plate 13. In this state, the ruler hook can use the longitudinal portion 31 and the hook plate 16 to hook or support the object to be measured to measure its length;

[0035] like Figure 8 As shown, when it is necessary to draw a line on the surface of an object to avoid interference between the longitudinal portion 31 and the object, the longitudinal portion 31 can be rotated counterclockwise around the rotating shaft 2 until the longitudinal portion 31 is in a horizontal state. At this time, the fixing protrusion 322 on the transverse portion 32 is clamped in the fixing hole 142 on the left side of the fixing plate 14, and the limiting portion 33 is separated from the accommodating cavity. In this state, the ruler hook can place the longitudinal portion 31 and the corresponding ruler tape on the surface of the object, and the operator can draw a line on the object along one side edge of the ruler tape.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
