[0002] Secure binding devices are widely used in cargo transportation and equipment securing. However, some defects exist in the safety binding devices currently on the market. First, during the retraction process, most binding devices cannot achieve uniform retraction speed, and some devices may even cause the webbing to hit the consumer's hand due to excessive retraction speed, posing a potential safety hazard. Second, during the retraction of the webbing, the unreasonable design of the gear structure assembled on the left and right sides of the webbing can easily cause jamming, resulting in uneven retraction of the webbing. Utility Model Content
[0003] In view of the above, the purpose of this utility model is to provide a binding device with a press-release mechanism to address the problems mentioned in the background art.
[0004] This solution provides a binding device with a press-release mechanism, comprising a main body; a central shaft rotatably mounted within the main body for winding webbing, with a left gear and a right gear at each end of the central shaft, both edges of which have internal grooves; a spring-loaded spring located on one side of the central shaft for providing power for webbing retraction; a press-release mechanism mounted on the main body, including a button mounted on the main body; a pressure plate cooperating with the button; a button spring providing a reset force for the button; and a handle spring providing a reset force for the pressure plate. The pressure plate restricts the rotation of the central shaft. When the button is pressed, the pressure plate releases the rotation restriction on the central shaft. When the button is not pressed, under the elastic force of the button spring and the handle spring, the pressure plate engages with the internal grooves of the left and right gears, restricting the rotation of the central shaft.
[0005] Furthermore, the bottom of the button is provided with a protrusion, and the pressure plate is provided with an end face that mates with the protrusion. When the button is pressed, the protrusion presses against the end face of the pressure plate, causing the pressure plate to disengage from the inner grooves of the left and right gears.
[0006] Furthermore, the protrusion of the button is the left and right end feet set at the bottom, and the end of the pressure plate is the first end face set in the middle. When the button is pressed, the left and right end feet press against the first end face, so that the left and right ends of the upper part of the pressure plate are respectively disengaged from the inner grooves of the left and right gears.
[0007] Furthermore, the protrusion of the button is a lower end foot set at the bottom, and the end face of the pressure plate is a second end face set at the lower part. When the button is pressed, the lower end foot presses against the second end face, causing the left and right ends of the second upper part of the pressure plate to disengage from the inner grooves of the left and right gears, respectively.
[0008] Furthermore, a damper is provided, which is assembled inside a left cover fixed to the left end of the main body. The head of the damper is provided with an inner groove that engages with the end of the central shaft. The upper and lower ends of the damper are prismatic structures. The interior of the left cover is provided with a prismatic inner groove that matches the prismatic structure of the damper. The damper and the left cover are fixed together by the prismatic structure.
[0009] Furthermore, it also includes a baffle plate, a safety plate, and a safety plate spring. The baffle plate is fixed to the main body, and the safety plate spring is connected to the safety plate. Under the action of the safety plate spring, the safety plate can prevent the left gear and the right gear from rotating.
[0010] Furthermore, it also includes a handle and a handle pin, the handle being assembled to the body via the handle pin, and the handle spring being connected to the handle to provide a restoring force for the handle.
[0011] Furthermore, it also includes a main shaft and a main shaft disc, the main shaft disc being assembled inside the main shaft, and the main shaft being connected to the central shaft.
[0012] Furthermore, the main body is also equipped with a front cover, which is fixed to the right end face of the main body by rivets.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By setting up a press-to-release mechanism, the restriction on the central axis can be released simply by pressing the button, which can effectively control the retraction of the webbing, making it safer and faster to use.
[0015] 2. The spring mechanism can serve as the driving force for the retraction of the webbing, preventing the webbing from retracting unevenly. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1 to 8The binding device shown includes a main body 24, a central shaft 08, a spring 03, a press-release mechanism, and a damper 18. The central shaft 08 is rotatably mounted inside the main body 24 for winding webbing. The spring 03 is located on one side of the central shaft 08, with one end connected to the central shaft 08 and the other end connected to the main body 24 or a right cover 02 on the main body 24, for providing power for the webbing to retract. The press-release mechanism is mounted on the main body 24 and includes a button 20, a pressure plate 22, a button spring 19, and a handle spring 21. The button 20 is mounted on the main body 24. The pressure plate 22 cooperates with the button 20. The button spring 19 and the handle spring 21 provide a restoring force for the button 20 and the pressure plate 22, respectively. The two ends of the central shaft 08 are respectively provided with a left gear 14 and a right gear 07. The edges of the left gear 14 and the right gear 07 are provided with inner grooves. The pressure plate 22 can cooperate with the inner grooves to restrict the rotation of the central shaft 08. The damper 18 is mounted in the left cover 17 located at the left end of the main body 24, and the head of the damper 18 cooperates with the inner groove at the end of the central shaft 08 to make the webbing retract at a uniform speed.
[0027] Furthermore, in the press-release mechanism, the bottom of the button 20 is provided with a protrusion, and the pressure plate 22 is provided with an end face that cooperates with the protrusion. When the button 20 is pressed, the protrusion presses against the end face of the pressure plate 22, causing the pressure plate 22 to disengage from the inner grooves of the left gear 14 and the right gear 07.
[0028] Furthermore, when the button 20 is not pressed, under the elastic force of the button spring 19 and the handle spring 21, the pressure plate 22 engages with the inner grooves of the left gear 14 and the right gear 07 to restrict the rotation of the central shaft 08 and achieve a braking effect.
[0029] Furthermore, the upper and lower ends of the damper 18 are prismatic structures, and the interior of the left cover 17 is provided with a prismatic inner groove that matches the prismatic structure of the damper 18. The damper 18 and the left cover 17 are fixed together by the prismatic structure.
[0030] Furthermore, the binding device also includes a main shaft 13 and a main shaft disc 23, the main shaft disc 23 being assembled inside the main shaft 13, and the main shaft 13 being connected to the central shaft 08.
[0031] Furthermore, a front cover 10 is also assembled on the main body 24, and the front cover 10 is fixed to the right end face of the main body 24 by rivets 01.
[0032] Furthermore, the binding device also includes a handle 15 and a handle pin 16. The handle 15 is mounted on the main body 24 via the handle pin 16. The handle spring 21 is connected to the handle 15 to provide a restoring force for the handle 15.
[0033] Furthermore, the main body 24 is also equipped with a baffle 09, a safety plate 12, and a safety plate spring 11. The baffle 09 is fixed to the main body 24, and the safety plate spring 11 is connected to the safety plate 12. Under the action of the safety plate spring 11, the safety plate 12 can prevent the left gear 14 and the right gear 07 from rotating. The safety plate 12 is used to enhance the safety of the device. When the pressure plate 22 disengages from the inner groove, the safety plate 12, under the action of the safety plate spring 11, engages with the inner grooves of the left gear 14 and the right gear 07 to prevent the webbing from rotating accidentally.
[0034] The assembly steps are as follows:
[0035] The spindle disc 23 is assembled into the spindle 13 to form a component for fixing the webbing. After fixing, it is assembled into the central shaft 08.
[0036] Left gear 14 and right gear 07 are respectively installed at the left and right ends of the central shaft 08;
[0037] Assemble the above components into the main body 24, and then install the handle spring 21, the guard ring 6 and the handle 15;
[0038] The damper 18 is assembled into the left cover 17 and fixed to the left end of the main body 24 by rivets 01.
[0039] The spring 03 is assembled onto the right cover 02, and the right end of the right gear 07 is fitted with a retaining ring 06, a retaining ring 05, and a washer 04.
[0040] After assembling the baffle 09 to the main body 24 and the safety spring 11 to the safety piece 12, the assembly is then assembled to the main body 24.
[0041] After the above components are assembled, the front cover 10 of the assembly part is fixed to the right end face of the main body 24 by rivets 01;
[0042] After assembling the pressure plate 22 to the main body 24, assemble the button spring 19 to the button 20, and then assemble it to the main body 24.
[0043] Instructions for use:
[0044] The spring force of the spring 03 allows the webbing to maintain a tendency to be pulled back after it has been pulled out.
[0045] By pulling up and down the handle 15 and pressing the button 20, the protruding part at the bottom of the button 20 presses down on the pressure plate 22, causing the pressure plate 22 to disengage from the inner grooves of the left gear 14 and the right gear 07. The webbing then rotates and retracts smoothly under the action of the spring 03. Similarly, when the button 20 is not pressed down, the pressure plate 22 presses against the inner grooves of the left gear 14 and the right gear 07 due to the elastic force of the button spring 19 and the handle spring 21, thereby achieving a braking effect and controlling the retraction speed.
[0046] By matching the prismatic shape of the upper and lower ends of the damper 18 with the prismatic shape inside the left cover 17, and by matching the head of the damper 18 with the inner groove at the end of the central shaft 08, the webbing can achieve a uniform speed during retraction and rotation through the action of friction.
[0047] In this embodiment, two different button and pressure plate design schemes are also provided. The difference between Scheme 1 and Scheme 2 lies in the specific structure of the button 20 and the pressure plate 22, but the working principle is the same. In Scheme 1, by pressing down on the pressing point 20A of the button 20, the left and right ends 20B of the lower part of the button 20 press down on the first end face 22A of the pressure plate 22, so that the left and right ends of the upper part 22B of the pressure plate 22 disengage from the inner grooves of the left gear 14 and the right gear 07, respectively. In Scheme 2, by pressing down on the second pressing point 20-1A of the button 20, the lower end 20-1B of the button 20 presses down on the second end face 22-1A of the pressure plate 22, so that the left and right ends of the second upper part 22-1B of the pressure plate 22 disengage from the inner grooves of the left gear 14 and the right gear 07, respectively. Both schemes can achieve smooth retraction and braking control of the webbing.
[0048] 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.
