Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a belt hole opener. Background Art

[0002] Belts are frequently used in weightlifting, fitness and daily use, but the holes are often limited when they leave the factory, so you need to drill holes yourself. The current simple punching tools are often punch nails or perforating nails, which penetrate the belt by hitting the upper end. This method not only easily causes the nail body to bend, but also cannot ensure that the hole is located in the center each time, and the distance between the two holes cannot be consistent. At present, industrial punching equipment cannot be small and easy to carry. Summary of the invention

[0003] The utility model aims at solving the problems existing in the prior art and provides a belt hole opener.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a puncher includes a fixed seat, clamping components arranged opposite to each other on both sides of the fixed seat along the belt punching direction, and a punching mechanism is provided at the center of the fixed seat; the clamping component includes a clamping piece installed on the side of the fixed seat, and the clamping piece maintains a tendency to move toward the fixed seat through an elastic piece; the two clamping pieces and the fixed seat surround and form a channel for the movement of the belt.

[0005] Preferably, it also includes a positioning wheel rotatably connected to the clamping member, the positioning wheel protrudes from the clamping member into the channel, and can rotate synchronously with the movement of the belt in the channel. The positioning wheel protrudes from the clamping member into the channel, and contacts the edge of the belt when the belt is located in the channel. When the belt moves along the length direction, the positioning wheel is driven to rotate synchronously under the action of friction. Positioning marks or scales are set on the positioning wheel along the circumferential direction. During operation, by observing the positioning marks or scales on the positioning wheel, the change in the distance of the belt movement in the channel that cannot be directly observed is converted into a change in the scale that can be directly observed. Without picking up the utility model, the distance between the two holes can be accurately located to achieve equidistant punching; unlike the current punching tools that use the naked eye to estimate the distance inaccurately, or measure with a ruler before operating to cause the punching position to be offset, the utility model is easy to operate and ensures that the distance between the two holes is more accurate.

[0006] Preferably, the clamping assembly further comprises a connecting rod, the outer end of the connecting rod is connected to the clamping member, and the inner end of the connecting rod is connected to the elastic member; notches are symmetrically arranged on both sides of the fixing seat, and the elastic member is connected to the fixing seat in the notches. The connecting rod and the elastic member are arranged in the notches, which shortens the width of the utility model in the belt width direction, makes the utility model smaller, protects the elastic member and the connecting rod, makes them less likely to be bent, and increases the structural strength.

[0007] Preferably, the fixing seat is a hollow structure, in which the punching mechanism is located, and the structure is compact.

[0008] Preferably, the punching mechanism includes a cylindrical punching nail penetrating the fixing seat and a speed reducing mechanism driving the punching nail to move up and down. The speed reducing mechanism drives the punching nail, and the punching nail moves smoothly, avoiding the problem of the nail body being bent due to the sudden force of the existing hammer, or the problem of the belt bending causing the shape of the hole to change.

[0009] Preferably, the punching nail comprises a punching portion with a smooth surface and a gradually decreasing diameter and a connecting portion with a threaded outer edge, and the connecting portion is threadedly connected to the fixing seat. The smooth surface of the punching nail is more conducive to punching, and the connecting portion is threadedly connected to the fixing seat to ensure that the punching nail remains in the same straight line when moving up and down. The speed reduction mechanism can be a component that uses a planetary gear or a gear set to drive the punching nail to move in the vertical direction.

[0010] Preferably, the deceleration mechanism includes a worm wheel ring, a worm and a knob; the worm wheel ring is rotatably connected to the fixed seat, the inner surface of the worm wheel ring is meshed with the thread of the punching nail connection part, the outer side of the worm wheel ring is meshed with the worm, and the outer end of the worm extends out of the fixed seat and is fixedly connected to the knob. The worm is driven to rotate by rotating the knob outside the fixed seat, the worm drives the worm wheel ring to rotate, and the worm wheel ring drives the punching nail to rotate, so that the punching nail moves up and down at a stable speed; and when the punching nail moves up and down, it also rotates along the thread, and the lower end of the punching part acts on the belt surface with not only vertical pressure, but also tangential force along the thread direction, making it easier for the utility model to punch holes on thicker belts.

[0011] Preferably, the punching nail is through in the middle. When the punching nail is through in the middle, the contact area between the lower end surface of the punching part and the belt is reduced, the pressure is greater under the same force, it is easier to cut the belt, and more labor can be saved during the punching process.

[0012] The punching nail is provided with a guide groove, the fixing seat is provided with a guide block, and a sliding block is connected between the guide block and the guide groove.

[0013] The beneficial effect of the utility model is that the clamping assembly and the fixing seat arranged relatively to each other surround and form a channel for the movement of the belt, and the clamping member and the fixing seat are connected by an elastic member. When an outward pulling force is applied to the clamping member, the elastic member is stretched, and the belt is placed in the channel at this time; when the pulling force is removed, the elastic member tends to retract, and the two clamping members automatically move toward the fixing seat until both clamping members contact the belt, thereby providing a continuous clamping force in the width direction of the belt, ensuring that the punching position is located at the center of the belt width, avoiding skewed punching, and it is easy to operate and can adapt to belts of different widths. The utility model has a simple structure and is easy to maintain; it is compact and easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0026] like Figure 1-7As shown, it is a specific embodiment of the utility model, comprising a fixed seat 1, a clamping assembly 2 arranged oppositely on both sides of the fixed seat 1 along the belt punching direction, and a punching mechanism 3 is arranged at the center of the fixed seat 1; the clamping assembly 2 comprises a clamping member 11 installed on the side of the fixed seat 1, and the clamping member 11 maintains a tendency to move toward the fixed seat through an elastic member; the two clamping members 11 and the fixed seat 1 surround and form a channel for the belt to move. The clamping member 11 is connected to the fixed seat 1 through an elastic member. When an outward pulling force is applied to the clamping member 11, the elastic member is stretched, and the belt is placed in the channel at this time; when the pulling force is removed, the elastic member tends to retract, and the two opposite clamping members 11 automatically move toward the fixed seat 1 until both clamping members 11 are in contact with the belt, thereby providing a continuous clamping force in the belt width direction, ensuring that the punching position is located at the center of the belt width, avoiding skewed punching, and it is easy to operate and can adapt to belts of different widths. This embodiment has a simple structure and is easy to maintain; it is compact and easy to carry.

[0027] The positioning wheel 14 is rotatably connected to the clamping member 11, and the positioning wheel 14 protrudes from the clamping member 11 into the channel, and can rotate synchronously with the movement of the belt in the channel. A scale is set on the positioning wheel 14 along the circumferential direction. During operation, it is not necessary to pick up this embodiment. By observing the scale on the positioning wheel 14, the distance between the two holes can be accurately located to achieve equidistant punching; unlike the traditional method of estimating the distance with the naked eye, which is inaccurate, or measuring with a ruler before operating, which leads to the deviation of the punching position, the utility model is easy to operate and ensures that the distance between the two holes is more accurate.

[0028] The clamping assembly 2 further includes a connecting rod 17, the outer end of which is connected to the clamping member 11, and the inner end of which is connected to the elastic member; slots 18 are provided on both sides of the fixing seat 1, and the connecting rod 17 is connected to the fixing seat 1 through the elastic member in the slots 18. The connecting rod 17 and the elastic member are arranged in the slots 18, which shortens the width of the utility model in the belt width direction, making the utility model smaller in size, and protecting the elastic member and the connecting rod 17, making them not easily bent, and increasing the structural strength.

[0029] The fixing seat 1 is a hollow structure, in which the punching mechanism 3 is located, and the structure is compact.

[0030] The punching mechanism 3 includes a cylindrical punching nail 12 penetrating the fixing seat 1 and a speed reducing mechanism driving the punching nail 12 to move up and down. The speed reducing mechanism drives the punching nail 12, and the punching nail 12 moves smoothly, avoiding the problem of the nail body being bent due to the sudden force of the existing hammer, or the problem of the belt bending causing the shape of the hole to change.

[0031] The punching nail 12 includes a punching portion 121 with a smooth surface and a gradually decreasing diameter and a connecting portion 122 with a threaded outer edge, and the connecting portion 122 is threadedly connected to the fixing seat 1. The smooth surface of the punching nail 12 is more conducive to punching, and the connecting portion 122 is threadedly connected to the fixing seat 1 to ensure that the punching nail 12 remains in the same straight line when moving up and down. The speed reduction mechanism can be a component that uses a planetary gear or a gear set to drive the punching nail 12 to move in the vertical direction.

[0032] The deceleration mechanism includes a worm wheel ring 16, a worm 15 and a knob 13; the worm wheel ring 16 is rotatably connected to the fixed seat 1, the inner surface of the worm wheel ring 16 is meshed with the thread of the connecting portion 122 of the punching nail 12, the outer side of the worm wheel ring 16 is meshed with the worm 15, and the outer end of the worm 15 extends out of the fixed seat 1 and is fixedly connected to the knob 13. The worm 15 is driven to rotate by rotating the knob 13 outside the fixed seat 1, the worm 15 drives the worm wheel ring 16 to rotate, and the worm wheel ring 16 drives the punching nail 12 to rotate, so that the punching nail 12 moves up and down at a stable speed; and when the punching nail 12 moves up and down, it also rotates along the thread, and the lower end of the punching portion 121 acts on the belt surface with not only vertical pressure, but also tangential force along the thread direction, making it easier for the utility model to punch holes on thicker belts.

[0033] The punching nail 12 is penetrated in the middle. The punching nail 12 is penetrated in the middle, and the contact area between the lower end surface of the punching part 121 and the belt is reduced. The pressure under the same force is greater, and it is easier to cut the belt, which can save more effort during the punching process. The upper part of the fixed seat 12 is symmetrically provided with a guide groove 20 at the left and right positions. The upper end surfaces of the guide grooves on both sides are fixedly provided with guide blocks 19. The guide blocks 19 are fixedly connected to the sliding blocks 21. The sliding blocks 21 are slidably connected in the guide grooves 20, which solves the guidance problem.

[0034] The specific usage of this embodiment is as follows:

[0035] Place the belt to be punched on the support, then pull the clamping member 11 of this embodiment outward to clamp the belt in the width direction, and place the bottom of the clamping member 11 on the upper surface of the support. The upper surface of the support, the inner surfaces of the two clamping members 11 arranged opposite to each other, and the lower surface of the bottom shell 18 form a channel, and the belt to be punched passes through the middle. Apply a force to the surface of the support by hand or other means to the embodiment so that the embodiment and the support remain relatively still when the belt is pulled.

[0036] The rotating knob 13 drives the worm 15 to rotate, the worm 15 drives the worm gear ring 16 to rotate, and the worm gear ring 16 drives the punching nail 12 to rotate, so that the punching nail 12 moves downward at a stable speed until the first hole is punched.

[0037] The belt is pulled in the length direction of the belt, and the positioning wheel 14 rotates with the movement of the belt. By observing the scale change of the positioning wheel 14, the belt is stopped from being pulled at the expected position and the holes are punched again.

[0038] The above-described embodiments are only descriptions of the preferred implementation methods of the utility model, and do not limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary personnel in this field to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
