Abstract
Description
Technical Field
[0001] This utility model relates to the field of trousers, and more particularly to a training trouser that can be quickly tightened. Background Technology
[0002] The purpose of training is to enable trainees to acquire a behavior or skill, similar to education. It emphasizes that through certain practice and repetition, trainees can achieve a predetermined goal or behavior. In the context of exercise, training means high-intensity exercise and long-term repetitive exercise.
[0003] During such high-intensity, long-duration exercise, trainees need to wear standardized, specialized training gear such as outerwear, pants, and footwear to protect their bodies. The design of these gears also enhances training efficiency and safety. Since pants are standard equipment, they cannot perfectly fit various body types. Therefore, items such as belts, drawstrings, and Velcro are used to tighten the waistband of the pants to prevent them from slipping down, restricting movement, increasing friction and causing discomfort, and reducing protection.
[0004] To ensure there is no foreign body sensation in the waist, drawstrings are a popular choice for tightening pants. However, after tightening, drawstrings need to be tied with knots to prevent them from coming loose. During high-intensity training, if the drawstrings come loose, the trainee may not be able to quickly restore the knots, and there is a possibility that the knots may be tied incorrectly and become difficult to untie and tighten the pants again, which may significantly affect the trainee's training process. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to solve the problem that: after the pull rope is tightened, it needs to be tied with a knot to prevent the pull rope from loosening. However, during high-intensity training, if the pull rope becomes loose, the trainee cannot quickly restore the knot, and there is a possibility that the knot may be tied incorrectly and it may be difficult to untie and tighten the pants again.
[0006] To solve the problems of the prior art, the technical solution of this utility model is as follows: It includes trousers and a waistband at the top of the trousers. A drawstring is provided inside the waistband, and a tightening box is provided on the surface of the waistband. The two ends of the drawstring pass through the left and right sides of the tightening box and exit along the other side. A resistance plate is connected to the inner wall of the tightening box near the waistband via a support rod. A perforation is formed on the surface of the resistance plate, and friction texture is provided on the inner wall of the perforation. A movable seat is fitted outside the support rod on the inner wall of the tightening box. A movable rod passes through the perforation on the surface of the movable seat. A groove is formed on the surface of the movable rod near the movable seat. The end of the movable rod extends to the outside of the tightening box and is provided with a pressing piece. A spring is provided between the movable seat and the inner wall of the tightening box.
[0007] Furthermore, the resistance plate has a protrusion on the side away from the support rod, and a perforation is provided on the side of the protrusion on the resistance plate. The two ends of the perforation are provided with rounded chamfers, which increases the inner wall area of the perforation and the area of the friction texture on the inner wall of the perforation. The rounded chamfers can prevent the pull rope from being resisted by excessive bending angle when it moves inside the perforation.
[0008] Furthermore, the friction texture on the inner wall of the perforation is composed of several annular protrusions evenly arranged perpendicular to the extension direction of the perforation, so that the pull rope will come into contact with the friction texture regardless of its movement state when passing through the perforation.
[0009] Furthermore, the groove on the surface of the movable rod is strip-shaped, and the width of the groove is twice the width of the pull rope. The side of the movable rod near the movable seat has a smooth transition. The groove allows the pull rope to have appropriate room to move, avoiding the situation where the pull rope is squeezed together due to insufficient room to move, and the smooth transition part can ensure that there is no gap between the movable seat and the pull rope when they come into contact.
[0010] Furthermore, the spring is always in a relaxed state, pushing the movable seat close to the resistance plate. The movable seat and the side of the clamping box closest to the spring are provided with a limiting protrusion. The spring is sleeved on the outside of the limiting protrusion, ensuring that the spring can always push the movable seat in a fixed position and preventing the spring from deviating from the required position due to external factors. It can also limit the maximum contraction range of the spring.
[0011] Furthermore, the two ends of the pull rope enter the slot from the left and right sides respectively, cross each other in the slot, and then leave. Subsequently, the ends of the pull rope extend to the outside of the tightening box through the perforation, ensuring that the pull rope is always inclined when passing through the perforation due to the position restriction of the slot on the surface of the movable rod, thereby ensuring that the pull rope obtains the maximum contact area with the perforation.
[0012] Furthermore, there are two support rods between the clamping box and the resistance plate. The two support rods are located on the left and right sides of the perforation, and the two support rods are arc-shaped plate structures facing each other, to ensure the stability of the resistance plate and obtain the best support strength.
[0013] Furthermore, the support rod between the tension box and the resistance plate has a groove at its bottom on the side near the resistance plate that is wider than the pull rope. The support rod is in contact with the sliding pull rope for a long time, causing the pull rope to suffer excessive wear and breakage.
[0014] Compared with the prior art, the advantages of this utility model are as follows:
[0015] This invention increases the friction of the pull rope during movement by setting a resistance plate with perforations on its surface inside the tension box. The movable seat, pushed by a spring, clamps the pull rope between the resistance plate and the movable seat. At this time, the pull rope is also subjected to clamping force and thrust from the movable seat, keeping it tightly against the inner wall of the perforations. This makes it difficult for the pull rope to move through the perforations, ensuring that the tensioning effect of the pull rope is not weakened. To relax the rope, press the pressing plate to move the movable seat and release its free movement. To tighten the rope, simply hold both ends and pull them directly to the sides. The overall operation is simple and quick, preventing loosening during training and eliminating the need for knots. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] like Figure 1-5 As shown, a type of training pants that can be quickly tightened includes pants 101 and a waistband 1 at the top of the pants 101. A drawstring 2 is provided inside the waistband 1, and a tightening box 3 is provided on the surface of the waistband 1. The two ends of the drawstring 2 are respectively inserted into the left and right sides of the tightening box 3 and pass out along the other side. A resistance plate 4 is connected to the inner wall of the tightening box 3 near the waistband 1 by a support rod. There are two support rods between the tightening box 3 and the resistance plate 4. The two support rods are located on the left and right sides of the perforation 5, and the two support rods are facing arc-shaped plate structures to ensure the stability of the resistance plate 4 and obtain the best support strength, so as to avoid damage due to external factors during training.
[0024] The resistance plate 4 has a perforation 5 on its surface, and the inner wall of the perforation 5 is provided with friction texture 6. The side of the resistance plate 4 away from the support rod has a protrusion. The perforation 5 is located on the side of the protrusion of the resistance plate 4, and the two ends of the perforation 5 are provided with rounded chamfers to increase the inner wall area of the perforation 5 and the area of the friction texture 6 on the inner wall of the perforation 5. The rounded chamfers can prevent the pull rope 2 from being resisted by the excessive bending angle when it moves inside the perforation 5, ensuring that the resistance experienced by the pull rope 2 is within a reasonable range, avoiding difficulty in pulling the pull rope 2 or the pull rope 2 being too loose. The friction texture 6 on the inner wall of the perforation 5 is composed of several annular protrusions that are evenly arranged perpendicular to the extension direction of the perforation 5, so that the pull rope 2 will contact the friction texture 6 when it passes through the perforation 5, regardless of its movement state.
[0025] A movable seat 7 is fitted on the outer side of the inner wall support rod of the tightening box 3. A movable rod 8 passing through the through hole 5 is provided on the surface of the movable seat 7. A through groove 9 is opened on the side of the movable rod 8 near the movable seat 7. The through groove 9 on the surface of the movable rod 8 is strip-shaped, and the width of the through groove 9 is twice the width of the pull rope 2. The side of the movable rod 8 near the movable seat 7 is smoothly transitioned. The through groove 9 allows the pull rope 2 to have appropriate movement space, avoiding the situation where the pull rope 2 is squeezed together due to insufficient movement space and jamming. The smooth transition part can ensure that there is no gap between the movable seat 7 and the pull rope 2 when they come into contact. The two ends of the pull rope 2 enter the through groove 9 from the left and right sides respectively, cross each other in the through groove 9 and then leave. Then the ends of the pull rope 2 extend to the outside of the tightening box 3 through the through hole 5, ensuring that the pull rope 2 is always passed through the through hole 5 in an inclined state due to the position restriction of the through groove 9 on the surface of the movable rod 8, thereby ensuring that the pull rope 2 and the through hole 5 obtain the maximum contact area.
[0026] The end of the movable rod 8 extends to the outside of the tightening box 3 and is provided with a pressing piece 10. A spring 11 is provided between the movable seat 7 and the inner wall of the tightening box 3. The spring 11 is always in a relaxed state, pushing the movable seat 7 close to the resistance plate 4. A limiting protrusion is provided on the side of the movable seat 7 and the tightening box 3 near the spring 11. The spring 11 is sleeved on the outside of the limiting protrusion to ensure that the spring 11 can always push the movable seat 7 to a fixed position and to prevent the spring 11 from being displaced from the required position due to external factors. It can also limit the maximum contraction range of the spring 11.
[0027] Working principle description: First, when it is necessary to tighten the waistband 1, the user presses down on the pressing plate 10. The pressing plate 10 pushes the movable rod 8, causing the movable seat 7 to move away from the resistance plate 4. At the same time, the groove 9 inside the movable rod 8 moves the pull rope 2, so that there is a certain distance between the pull rope 2 and the inner wall of the perforation 5 of the resistance plate 4, and the pressure of the movable seat 7 is removed. At this time, the operator can directly pull the end of the pull rope 2 extending along the tightening box 3. When the tightness feels appropriate, the pressing plate 10 is released. Under the action of the spring 11, The movable seat 7 moves closer to the resistance plate 4, and the movable seat 7 drives the movable rod 8 to move towards the resistance plate 4. The movable rod 8 then drives the pull rope 2 to approach the friction texture 6 on the inner wall of the perforation 5 through the slot 9. At the same time, the movable seat 7 clamps the pull rope 2 between the resistance plate 4 and the movable seat 7. When the middle of the pull rope 2 receives tension, the interlaced pull ropes 2 inside the slot 9 will open to both sides and fit more tightly with the friction texture 6 on the inner wall of the perforation 5, ensuring that the middle of the pull rope 2 will not retract and loosen when subjected to tension.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
