Description

Technical Field

[0001] The utility model relates to the technical field of leather case measuring tapes, in particular to a leather case measuring tape capable of being unlocked by pressing. Background Art

[0002] The tape measure is a commonly used measuring tool in life. Usually, the tape measure consists of a shell, a tape and a hook at the end of the tape. The tape can be retracted into the shell and extended out of the shell. When in use, the tape is pulled out by pulling the hook, and the hook is hung in a suitable position. The clamping plate on the inner wall of the shell is used to fix the tape to the inner wall of the shell to start measuring. After the measurement work is completed, the clamping plate is pushed back to the inner wall of the shell to quickly reel the tape into the inner wall of the shell.

[0003] However, in use, the existing tape measure uses the clamping plate provided on the inner wall to cooperate with the inner wall of the shell to push the tape against the inner wall of the shell, thereby fixing the tape on the inner wall of the shell. The clamping plate and the inner wall of the shell interact with each other through friction, so that the clamping plate is fixed to the inner wall of the shell. When the user pulls back the clamping plate, it is necessary to use a large force to overcome the friction, resulting in the rapid separation of the clamping plate from the inner wall of the shell, and one end of the tape that is quickly rewound is prone to uneven force and rapid swinging, and the user will not react in time, which is easy to cause damage to the user's hand, which is not conducive to the user's recovery of the tape after the measurement work is completed. For this reason, we propose a leather case tape measure with a push-to-unlock function. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leather measuring tape with a push-to-unlock function, comprising a measuring tape body; a measuring tape, which is wrapped around the inner wall of the measuring tape body and is used by the user to stretch the measuring tape to perform measurements; and a pressing mechanism, which is located on the inner wall of the measuring tape body and is used to press and drive the measuring tape to retract and roll back into the inner wall of the measuring tape body.

[0006] Among them, the pressing mechanism includes a cylinder rotatably connected to the inner wall of the tape measure body, the tape is wrapped around the surface of the cylinder, the inner wall of the cylinder is fixedly connected with a coil spring, one end of the tape measure is fixedly connected to the inner wall of the tape measure body, and a clamp is provided on one side of the cylinder, which is slidably connected to the inner wall of the tape measure body.

[0007] Among them, the clamping part includes a round rod slidably connected to the inner wall of the tape measure body, a ratchet 1 is provided on the inner wall of the cylinder near the round rod, the round rod is slidably connected to the ratchet 1, one end of the round rod is fixedly connected to the ratchet 2, the ratchet 2 is slidably connected to the ratchet 1, a steel sheet is fixedly connected to the surface of the round rod, and one end of the steel sheet is fixedly connected to the inner wall of the ratchet body.

[0008] Wherein, a sliding area and a clamping groove area are provided between the first ratchet and the second ratchet.

[0009] Wherein, limit blocks are arranged on both sides of the surface of the round rod, and a limit groove is arranged on the inner wall of the tape measure body, and the limit groove is slidably connected with the limit block.

[0010] Among them, a port is provided on the inner wall of the tape measure body, the port is slidably connected to the tape measure, an arc-shaped groove is provided on the inner wall of the port, a clamping block is slidably connected to the inner wall of the arc-shaped groove, a roller one is rotatably connected to the inner wall of the clamping block, roller one is slidably connected to the surface of the tape measure, and roller two is rotatably connected to the side of the inner wall of the port away from the arc-shaped groove.

[0011] The first roller is located on the opposite side of the second roller, and the inner wall of the arc groove is provided with an extrusion area, which is placed close to the second roller.

[0012] The utility model has at least the following beneficial effects: when the user uses the tape measure body to perform measurement, the user stretches the length of the tape from the inner wall of the tape measure body. After the measurement is completed, the round rod is pressed to separate the ratchet 1 from the ratchet 2, and the cylinder is driven by the winding spring to reverse and wind the tape. When the tape slides from the inner wall of the port, the tape drives the roller 1 to move, so that the roller 1 squeezes the tape, thereby limiting the speed of the tape when it is rewound, which is beneficial to reduce the swing of the tape when it is rewound and protect the safety of the user when operating the tape rewinding.

DETAILED DESCRIPTION

[0019] 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 the embodiments. 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.

[0020] Embodiment 1

[0021] See also Figure 1-5 The utility model provides a technical solution: a push-to-unlock leather measuring tape, comprising a measuring tape body 1; a measuring tape 2, which is wound around the inner wall of the measuring tape body 1 and is used by a user to stretch the measuring tape 2 to perform measurements; a pressing mechanism 3, which is located on the inner wall of the measuring tape body 1 and is used to press and drive the measuring tape 2 to retract and rewind into the inner wall of the measuring tape body 1. When the user uses the measuring tape body 1 to perform measurements, the user first pulls one end of the measuring tape 2 and stretches the length, and after the measurement is completed, presses the pressing mechanism 3 to retract and rewind the measuring tape 2, and prevents one end of the measuring tape 2 from swinging when the measuring tape 2 is rewound quickly, thereby causing accidental injury to the user. This is beneficial for the user to quickly and conveniently recover the measuring tape 2 and perform the next step of measurement.

[0022] The pressing mechanism 3 includes a cylinder 30 rotatably connected to the inner wall of the tape measure body 1, and the tape 2 can be wound around the surface of the cylinder 30 in an orderly manner, so that when the tape 2 is not in use, the length of the tape 2 can be retracted to the inner wall of the tape measure body 1. The tape 2 is wound around the surface of the cylinder 30, and a coil spring 31 is fixedly connected to the inner wall of the cylinder 30. When the cylinder 30 rotates to stretch the length of the tape 2, the cylinder 30 squeezes the coil spring 31 to deform, and when the tape 2 needs to be recovered, the coil spring 31 drives the cylinder 30 to rotate in the opposite direction, so that the tape 2 is rewound around the surface of the cylinder 30, and one end of the tape measure is connected to the inner wall of the cylinder 30. The inner wall of the tape measure body 1 is fixedly connected, and a clamp 32 is provided on one side of the cylinder 30, which can limit the movement of the tape 2 on the inner wall of the tape measure body 1, so that when the clamp 32 releases the restriction on the tape 2, the tape 2 can quickly and easily enter the inner wall of the tape measure body 1. The clamp 32 is slidably connected to the inner wall of the tape measure body 1. When the user presses the clamp 32 on one side of the tape measure body 1, the clamp 32 releases the restriction on the cylinder 30. Under the reaction force of the winding spring 31, the cylinder 30 drives the cylinder 30 to reverse and wrap around the tape 2, so that the tape 2 shrinks orderly on the inner wall of the tape measure body 1.

[0023] The clamp 32 includes a round rod 33 slidably connected to the inner wall of the tape measure body 1, and can slide linearly on the inner wall of one side of the tape measure body 1. The inner wall of the cylinder 30 near the round rod 33 is provided with a ratchet 1 34, which can be used in conjunction with a ratchet 2 35, so that the rotation of the cylinder 30 on the inner wall of the tape measure body 1 is limited. The round rod 33 is slidably connected to the ratchet 1 34, and one end of the round rod 33 is fixedly connected to the ratchet 2 35, which can limit the sliding of the ratchet 1 34 on the surface of the ratchet 2 35, and make the ratchet 1 34 move in a specific direction when sliding on the surface of the ratchet 2 35. The ratchet 2 35 is slidably connected to the ratchet 1 34, and a steel sheet 36 is fixedly connected to the surface of the round rod 33, which can be So that the round rod 33 can reciprocate on the inner wall of the tape measure body 1, one end of the steel sheet 36 is fixedly connected to the inner wall of the ratchet body, and the user presses the round rod 33 to squeeze the steel sheet 36. At the same time, the round rod 33 drives the second ratchet 35 to separate from the first ratchet 34, so that the cylinder 30 drives the first ratchet 34 to rotate synchronously under the action of the coil spring 31, or when the cylinder 30 rotates to stretch the length of the tape 2, the cylinder 30 drives the first ratchet 34 to slide on the surface of the second ratchet 35, so that the second ratchet 35 drives the round rod 33 to repeatedly squeeze the steel sheet 36, which is beneficial to control the tape 2 to move in a single direction from the inner wall of the ratchet body to prevent the tape 2 from suddenly shrinking.

[0024] A sliding area 37 and a groove area 38 are provided between the ratchet tooth 1 34 and the ratchet tooth 2 35. The sliding area 37 allows the ratchet tooth 1 34 to move in a specific direction on the surface of the ratchet tooth 2 35, and the groove area 38 allows the ratchet tooth 1 34 and the ratchet tooth 2 35 to squeeze each other, limiting the tendency of the cylinder 30 to drive the ratchet tooth 1 34 to move in the opposite direction under the action of the coil spring 31.

[0025] Limit blocks 39 are provided on both sides of the surface of the round rod 33, which can be used in conjunction with the limit groove 310 to allow the round rod 33 to move linearly along the inner wall of the tape measure body 1. The limit groove 310 is provided on the inner wall of the tape measure body 1, so that when the ratchet 1 34 and the ratchet 2 35 are squeezed against each other, the round rod 33 will not be driven by the ratchet 2 35 to rotate, which is beneficial to limiting the movement of the ratchet 1 34 and the cylinder 30. The limit groove 310 is slidably connected to the limit block 39.

[0026] The inner wall of the tape measure body 1 is provided with a port 311, which allows the tape 2 to be retracted and released from the port 311, which is conducive to controlling the tape 2 to be wound around the surface of the cylinder 30 in an orderly manner. The port 311 is slidably connected to the tape 2, and the inner wall of the port 311 is provided with an arc groove 312, which allows the block 313 to move along the inner wall of the arc groove 312. The inner wall of the arc groove 312 is slidably connected with the block 313, which can drive the roller 1 314 to move on the inner wall of the arc groove 312. The inner wall of the block 313 is rotatably connected with the roller 1 314. Under the drive of the tape 2, the inner wall of the block 313 rotates, and at the same time, it is subjected to the sliding friction force generated between the tape 2 and the roller 1 314 and the surface of the tape 2 are slidably connected. The inner wall of the port 311 away from the arc groove 312 is rotatably connected with the roller 2 315, which can slide on the upper end of the tape 2, so that the roller 1 314 and the roller 2 315 are respectively located above and below the surface of the tape 2.

[0027] When the tape 2 is retracted and rolled back, the tape 2 has a relatively high speed at the initial stage of rolling back, so that the tape 2 and the port 311 are squeezed and collided. At the same time, the tape 2 moves between the roller 1 314 and the roller 2 315, so that the friction between the tape 2 and the roller 1 314 drives the clamping block 313 to move along the arc groove 312, so that the roller 1 314 squeezes the tape 2, thereby limiting the speed of the tape 2 when it is rolled back. When the speed of the tape 2 gradually slows down, the friction force on the tape 2 is reduced. Under the action of the inner wall of the tape 2, the clamping block 313 is driven to move in the opposite direction on the inner wall of the arc groove 312, which is beneficial to controlling the speed of the tape 2 when it is rolled back, and preventing the tape 2 from rolling back too much, causing one end of the tape 2 to swing, affecting the user's use of the tape measure body 1 to roll back the tape 2.

[0028] Embodiment 2

[0029] Roller 1 314 is located on the positive opposite side of roller 2 315, and an extrusion area 316 is provided on the inner wall of the arc groove 312. When the tape 2 enters the port 311 at a normal speed, roller 1 314 and roller 2 315 slide on the surface of the tape 2 at the same time. When the speed of the tape 2 is faster, the block 313 is pulled to move on the inner wall of the arc groove 312, so that roller 1 314 is squeezed on the surface of the tape 2, which has the effect of slowing down the speed of the tape 2. When the speed of the tape 2 changes, the friction between the tape 2 and roller 1 314 changes in time, so that the extrusion pressure between roller 1 314 and the tape 2 changes, which is beneficial to control the speed of the tape 2 when it is rolled back, thereby protecting the safety of the tape measure body 1 when using it. The extrusion area 316 is placed close to roller 2 315.
