[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned rope threading device is long in length and large in size, is not suitable for home use, and is not convenient for storage and carrying. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a trousers stringing device.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a trousers stringing device, comprising a shell, a through hole is penetrated through the side wall of the shell, a rotating shaft rotatably connected to the shell is penetrated through the shell, the lower end of the rotating shaft is rotatably connected to the inner bottom wall of the shell, a turntable is fixed to the upper end of the rotating shaft, a steel coil is sleeved on the rotating shaft, the end of the steel coil away from the rotating shaft passes through the through hole, a mounting block is fixed to the end of the steel coil away from the rotating shaft, a fixing clamp is fixed to the side wall of the mounting block, a movable clamp symmetrically arranged with the fixing clamp is slidably connected to the side wall of the mounting block, and a driving component for driving the movable clamp to move is installed on the mounting block.

[0007] By adopting the above technical solution, when it is necessary to thread the drawstring, the user pulls the steel coil outward through the mounting block and inserts it into the seam at one end of the pants, and then extends it out from the seam at the other end of the pants, places the drawstring on the fixed clip, drives the movable clip to move downward and press against the drawstring through the driving component, and then pulls the steel coil out of the seam, thereby threading the drawstring into the pants. After use, the user rotates the rotating shaft through the turntable to retract the steel coil into the shell, which is convenient for storing and carrying the drawstring device.

[0008] Furthermore, a side wall of the mounting block away from the steel coil is provided with a sliding groove, and the driving assembly includes a slider fixed to the side wall of the movable clamp and slidingly connected to the inner wall of the sliding groove, a screw rod penetrating the mounting block and rotatably connected, and a rotating block fixed to the upper end of the screw rod, the lower end of the screw rod is rotatably connected to the inner bottom wall of the sliding groove, and the screw rod penetrates the slider and is threadedly connected to the slider.

[0009] By adopting the above technical solution, when the drawstring needs to be fixed, the user rotates the screw by turning the block. Since the screw is threadedly connected to the slider, and the slider is slidingly connected to the inner wall of the slide groove, the slider moves axially along the screw, driving the movable clamp downward to cooperate with the fixed clamp and press against the drawstring, thereby reducing the probability of the drawstring falling off during the threading process.

[0010] Furthermore, a coil spring is sleeved on the rotating shaft, one end of the coil spring is fixed to the side wall of the rotating shaft, the steel coil is sleeved on the coil spring, and one end of the coil spring away from the rotating shaft is fixed to the end of the steel coil.

[0011] By adopting the above technical solution and setting the coil spring, the steel coil automatically contracts under the action of the coil spring, which facilitates the rapid recovery of the steel coil and reduces the probability of the steel coil moving outward.

[0012] Furthermore, a fixing groove is provided on the upper surface of the shell, and a limiting assembly for limiting the turntable is installed on the turntable. The limiting assembly includes a threaded rod that passes through the turntable and is threadedly connected, a handle fixed to the upper end of the threaded rod, and a limiting block fixed to the lower end of the threaded rod.

[0013] By adopting the above technical solution, after the steel coil is pulled out, the staff rotates the threaded rod by the handle to move the threaded rod downward, and makes the limit block press downward against the bottom wall of the fixed groove, thereby limiting the turntable and facilitating the steel coil to maintain a fixed length.

[0014] Furthermore, a rubber sheet is fixed to the bottom of the limit block.

[0015] By adopting the above technical solution, the rubber sheet is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the limit block and the fixing groove and enhances the limiting effect of the limit assembly.

[0016] Furthermore, the upper surface of the fixed clamp and the lower surface of the movable clamp are both provided with serrated grooves.

[0017] By adopting the above technical solution and setting the serrated groove, the friction between the upper surface of the fixed clamp and the lower surface of the movable clamp is increased, further reducing the probability of the drawstring falling off.

[0018] Furthermore, a rubber pad is fixed to the side wall of the mounting block close to the shell.

[0019] By adopting the above technical solution, the rubber pad is made of rubber material, and the material is elastic, which plays a buffering role between the mounting block and the shell, thereby reducing the wear between the mounting block and the shell.

[0020] Furthermore, a rounded corner is provided at the intersection between the inner wall of the through hole and the side wall of the shell.

[0021] By adopting the above technical solution, the rounded corners reduce the friction between the steel coil and the through hole, thereby reducing the wear on the steel coil.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In the present application, when the drawstring needs to be threaded, the user pulls the steel coil outward through the mounting block and inserts it into the seam at one end of the pants, and then extends the drawstring from the seam at the other end of the pants, places the drawstring on the fixed clip, drives the movable clip to move downward and press against the drawstring through the driving assembly, and then pulls the steel coil out of the seam, thereby threading the drawstring into the pants. After use, the user rotates the rotating shaft through the turntable to retract the steel coil into the housing, which is convenient for storage and carrying of the drawstring device;

[0024] 2. In the present application, when the drawstring needs to be fixed, the user rotates the screw by turning the block. Since the screw is threadedly connected to the slider, and the slider is slidably connected to the inner wall of the slide groove, the slider moves along the axial direction of the screw, driving the movable clamp downward to cooperate with the fixed clamp and press against the drawstring, thereby reducing the probability of the drawstring falling off during the threading process;

[0025] 3. In the present application, the setting of the coil spring enables the steel coil to automatically contract under the action of the coil spring, which facilitates the rapid recovery of the steel coil and reduces the probability of the steel coil moving outward.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-3 As shown, the embodiment of the present application discloses a trousers stringing device, including a housing 1, a rotating shaft 2, a rotating disk 21, a steel coil 3, a mounting block 4, a fixed clamp 5, a movable clamp 6 and a driving assembly 7.

[0032] The shell 1 is a rectangular parallelepiped structure, and a through hole 101 is provided through the side wall of the shell 1. The rotating shaft 2 is a vertically arranged round rod-shaped structure, and the rotating shaft 2 is provided through the shell 1 and is rotatably connected, and the lower end of the rotating shaft 2 is rotatably connected to the inner bottom wall of the shell 1. The turntable 21 is a disc-shaped structure, and the turntable 21 is fixed to the upper end of the rotating shaft 2, and the axis of the turntable 21 coincides with the axis of the rotating shaft 2. The steel coil 3 is sleeved on the rotating shaft 2, and the end of the steel coil 3 away from the rotating shaft 2 passes through the through hole 101. The mounting block 4 is a rectangular parallelepiped structure, and the mounting block 4 is fixed to the end of the steel coil 3 away from the rotating shaft 2, and a sliding groove 41 is provided on the side wall of the mounting block 4 away from the steel coil 3. The fixed clamp 5 is fixed on the side wall of the mounting block 4, and the fixed clamp 5 is arranged at a position on the side wall of the mounting block 4 near the bottom of the mounting block 4. The movable clamp 6 is slidably connected to the side wall of the mounting block 4, and the movable clamp 6 and the fixed clamp 5 are symmetrically arranged.

[0033] The driving assembly 7 is mounted on the mounting block 4 and is used to drive the movable clamp 6 to move. The driving assembly 7 includes a slider 71, a screw rod 72 and a rotating block 73. The slider 71 is a rectangular parallelepiped structure. The slider 71 is fixed to the side wall of the movable clamp 6. The slider 71 is slidably connected to the inner wall of the slide groove 41. The screw rod 72 is a vertically arranged rod-shaped structure. The screw rod 72 is penetrated and rotatably connected to the mounting block 4. The lower end of the screw rod 72 is rotatably connected to the inner bottom wall of the slide groove 41. The screw rod 72 penetrates the slider 71 and is threadedly connected to the slider 71. The rotating block 73 is a round block structure. The rotating block 73 is fixed to the upper end of the screw rod 72, and the axis of the rotating block 73 coincides with the axis of the screw rod 72.

[0034] When it is necessary to thread the drawstring, the user pulls the steel coil 3 outward through the mounting block 4 and inserts it into the seam at one end of the pants, then extends it out from the seam at the other end of the pants, places the drawstring on the fixing clamp 5, and rotates the screw 72 through the rotating block 73. Since the screw 72 is threadedly connected to the slider 71, the slider 71 is slidingly connected to the inner wall of the slide groove 41, so that the slider 71 moves axially along the screw 72, driving the movable clamp 6 downward to cooperate with the fixing clamp 5 and press against the drawstring, and then the steel coil 3 is pulled out from the seam, thereby threading the drawstring into the pants. After use, the user rotates the rotating shaft 2 through the turntable 21 to recycle the steel coil 3 into the shell 1, which is convenient for storing and carrying the drawstring device.

[0035] In order to facilitate the rapid recovery of the steel coil 3, a coil spring 8 is sleeved on the rotating shaft 2, one end of the coil spring 8 is fixed to the side wall of the rotating shaft 2, the steel coil 3 is sleeved on the coil spring 8, and the end of the coil spring 8 away from the rotating shaft 2 is fixed to the end of the steel coil 3. The setting of the coil spring 8 allows the steel coil 3 to automatically shrink under the action of the coil spring 8, thereby facilitating the rapid recovery of the steel coil 3 and reducing the probability of the steel coil 3 moving outward.

[0036] In order to keep the steel coil 3 at a fixed length, a fixing groove 102 is provided on the upper surface of the housing 1. A limiting assembly 9 is installed on the turntable 21 to limit the turntable 21. The limiting assembly 9 includes a threaded rod 91, a handle 92 and a limiting block 93. The threaded rod 91 is a vertically arranged rod-shaped structure. The threaded rod 91 is penetrated and threadedly connected to the turntable 21. The handle 92 is a vertically arranged round rod-shaped structure. The handle 92 is fixed at the upper end of the threaded rod 91, and the axis of the handle 92 coincides with the axis of the threaded rod 91. The limiting block 93 is a round block-shaped structure. The limiting block 93 is fixed at the lower end of the threaded rod 91, and the axis of the limiting block 93 coincides with the axis of the threaded rod 91. After the steel coil 3 is pulled out, the staff rotates the threaded rod 91 through the handle 92 to move the threaded rod 91 downward, and the limiting block 93 is pressed downward against the inner bottom wall of the fixing groove 102, thereby limiting the turntable 21, so as to facilitate keeping the steel coil 3 at a fixed length.

[0037] In order to enhance the limiting effect of the limiting assembly 9, a rubber sheet 10 is fixed to the bottom of the limiting block 93. The rubber sheet 10 is made of rubber material and has a large friction coefficient on its surface, which increases the friction between the limiting block 93 and the fixing groove 102, thereby enhancing the limiting effect of the limiting assembly 9.

[0038] In order to further reduce the probability of the drawstring falling off, a serrated groove 11 is provided on the upper surface of the fixed clamp 5 and the lower surface of the movable clamp 6. The setting of the serrated groove 11 increases the friction between the upper surface of the fixed clamp 5 and the lower surface of the movable clamp 6, thereby further reducing the probability of the drawstring falling off.

[0039] In order to reduce the wear between the mounting block 4 and the shell 1, a rubber pad 12 is fixed to the side wall of the mounting block 4 close to the shell 1. The rubber pad 12 is made of rubber material, which is elastic and has a buffering effect between the mounting block 4 and the shell 1, thereby reducing the wear between the mounting block 4 and the shell 1.

[0040] In order to reduce the wear on the steel coil 3 , a rounded corner 103 is provided at the intersection between the inner wall of the through hole 101 and the side wall of the shell 1 . The rounded corner 103 reduces the friction between the steel coil 3 and the through hole 101 , thereby reducing the wear on the steel coil 3 .

[0041] The operating principle of the trousers stringing device in this embodiment is as follows: when it is necessary to string the trousers, the user pulls the steel coil 3 outward through the mounting block 4 and inserts it into the seam at one end of the trousers, and then extends the drawstring from the seam at the other end of the trousers, places the drawstring on the fixing clamp 5, and rotates the screw rod 72 through the rotating block 73. Since the screw rod 72 is threadedly connected to the slider 71, and the slider 71 is slidably connected to the inner wall of the slide groove 41, the slider 71 moves axially along the screw rod 72, driving the movable clamp 6 downward to cooperate with the fixing clamp 5 and press against the drawstring, and then the steel coil 3 is pulled out from the seam, thereby threading the drawstring into the trousers. After use, the user rotates the rotating shaft 2 through the turntable 21 to recycle the steel coil 3 into the shell 1, which is convenient for storing and carrying the stringing device.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
