Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping technology, and in particular to an adjustable locking quick clamp. Background Technology

[0002] As a basic mechanical component, clamps are widely used in manufacturing, transportation, and daily life to fix and hold various workpieces or equipment, especially tubular objects. A well-designed clamp needs to provide a stable and reliable clamping force to ensure the safety of the fixed object during operation or transportation.

[0003] With the diversification of application scenarios, the tubular objects that need to be fixed often have different diameter specifications. To meet this need, some existing clamps use different thickness rubber pads to change the clamping inner diameter. However, this method has obvious shortcomings. Users need to prepare multiple sets of pads, and they need to disassemble and replace them during adjustment. The process is cumbersome, time-consuming, and labor-intensive. Moreover, the replaced pads are easy to lose, which greatly reduces the convenience of use.

[0004] More importantly, in many public or semi-public settings, such as when securing equipment to the exterior of vehicles or public facilities, the security of the clamps becomes a critical consideration. Existing adjustment methods, whether replacing gaskets or simply tightening screws, lack anti-theft mechanisms in their adjustment mechanisms. This means anyone can easily loosen the clamps, potentially leading to the theft of valuable equipment and even safety incidents due to loosening. Current technological solutions often fail to effectively combine convenient size adjustment with reliable anti-theft locking in a single, compact structure.

[0005] Therefore, this utility model proposes an adjustable locking quick clamp to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adjustable locking quick clamp, which aims to improve the existing adjustable locking quick clamps, which have cumbersome adjustment process, limited application range, and generally lack effective anti-theft locking function, resulting in inconvenience and low security.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable locking quick clamp, comprising: an adjustment mechanism and a clamping mechanism, wherein the adjustment mechanism is mounted on the top of the clamping mechanism; The adjustment mechanism includes a key, a lock cylinder, a lock block protective cover, a lock cylinder cover, and a lock block, as well as a clamping mechanism. The lock cylinder is adapted to the key, the lock block is rotatably connected to the end of the lock cylinder, and the lock cylinder cover covers the outside of the lock cylinder. The clamping mechanism includes a first pipe clamp, a second pipe clamp, a third pipe clamp, a first soft rubber, a second soft rubber, an iron sheet, and a first fastening screw. The lock block protective cover covers the outside of the lock cylinder cover. The first pipe clamp, the second pipe clamp, and the third pipe clamp together form a clamping space for clamping pipe fittings. The first soft rubber is fixedly connected to the inner wall of the first pipe clamp, and the second soft rubber is fixedly connected to the inner walls of the second and third pipe clamps. The bottoms of the second and third pipe clamps are connected by the iron sheet.

[0008] Preferably, the first fastening screw passes through the iron plate to fix the second pipe clamp to the third pipe clamp.

[0009] Preferably, it also includes a second fastening screw, which is disposed on the clamping mechanism for fixing the entire clamp to the external carrier.

[0010] Preferably, the gear adjustment part of the first pipe clamp has a pressable button and a rack integrally formed with the button.

[0011] Preferably, the second and third pipe clamps are provided with corresponding toothed grooves that mesh with the rack, and the first pipe clamp can slide relative to the second and third pipe clamps to adjust the gear position.

[0012] Preferably, the lock block can rotate 90 degrees under the drive of the lock cylinder to switch between the locked position and the unlocked position.

[0013] Preferably, when the lock block is in the locked position, the side wall of the lock block abuts against the button to restrict its pressing.

[0014] Preferably, when the lock block is in the unlocked position, the sidewall of the lock block is separated from the button to allow it to be pressed.

[0015] Preferably, the structural dimensions of the first pipe clamp, the second pipe clamp, and the third pipe clamp are adapted to pipe fittings with a diameter of 1.2 to 2.0 inches.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting an adjustment mechanism composed of a key, a lock cylinder and a lock block, and by using the rotation of the lock block to selectively lock or release the gear adjustment part of the clamping mechanism, the problem of existing clamps not having anti-theft function and clamped pipes being easily stolen or arbitrarily disassembled is solved, thus achieving reliable locking of the clamping state and significantly improving the security and anti-theft performance of the equipment.

[0017] 2. This utility model solves the problems of existing clamps that are only suitable for a single pipe diameter or require the replacement of rubber pads of different thicknesses for adjustment, by setting a first pipe clamp with a pressable button and a rack, and making it slide to engage with the second and third pipe clamps with toothed grooves. This solves the problems of existing clamps that are cumbersome to operate and inefficient, because they are only suitable for a single pipe diameter or require the replacement of rubber pads of different thicknesses for adjustment. It achieves the effect of quickly adjusting the clamping diameter without any tools or additional parts, and can be adapted to various specifications of pipe fittings, which greatly improves the convenience of use and work efficiency.

[0020] 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.

[0021] Reference Figures 1-5 This utility model provides an adjustable locking quick clamp, which aims to solve the problems of existing clamps having a single applicable pipe diameter, cumbersome adjustment, and lack of locking function, resulting in inconvenience and insufficient safety.

[0022] Specifically, it includes an adjustment mechanism 1 and a clamping mechanism 2 fixedly connected to the adjustment mechanism 1. The adjustment mechanism 1 is used to control the locking and unlocking of the pipe diameter adjustment function of the clamping mechanism 2, while the clamping mechanism 2 is used to securely clamp pipe fittings of different diameters.

[0023] The adjustment mechanism 1 includes a key 101, a lock cylinder 102, a lock block protective cover 103, a lock cylinder cover 104, and a lock block 105. The clamping mechanism 2 includes a first tube clamp 201, a second tube clamp 202, a third tube clamp 203, a first soft rubber 204, a second soft rubber 205, an iron sheet 206, and a first fastening screw 207. The adjustment mechanism 1 is installed on top of the clamping mechanism 2. This integrated setup allows the locking and adjustment operations to be located in the same area, making it convenient for users to control with one hand. The lock cylinder 102 and the key 101 are compatible with each other and are used to receive the user's rotation command. The lock block 105 is rotatably connected to the end of the lock cylinder 102 and acts as an actuator to directly lock or release the clamping mechanism 2. The lock cylinder cover 104 covers the outside of the lock cylinder 102 and provides support and protection for the lock cylinder 102. The lock block protective cover 103 covers the outside of the lock cylinder cover 104, further enhancing the dustproof and waterproof performance and structural strength of the entire adjustment mechanism 1.

[0024] In the structure of clamping mechanism 2, the first pipe clamp 201, the second pipe clamp 202, and the third pipe clamp 203 together enclose a clamping space for clamping pipe fittings. The first soft rubber 204 is fixedly connected to the inner wall of the first pipe clamp 201, and the second soft rubber 205 is fixedly connected to the inner walls of the second pipe clamp 202 and the third pipe clamp 203. The presence of the first soft rubber 204 and the second soft rubber 205 increases the friction during clamping and can effectively protect the surface of the clamped pipe fittings from damage. The bottoms of the second pipe clamp 202 and the third pipe clamp 203 are connected by an iron plate 206. The first fastening screw 207 passes through the iron plate 206 to fix the second pipe clamp 202 and the third pipe clamp 203, so that the second pipe clamp 202 and the third pipe clamp 203 form a structurally stable whole, which facilitates subsequent sliding adjustment. The first fastening screw 207 can also be used to fine-tune the clamping force between the second pipe clamp 202 and the third pipe clamp 203.

[0025] The first clamp 201 is provided with a gear adjustment part, which includes a pressable button and a rack integrally formed with the button. The second clamp 202 and the third clamp 203 are respectively provided with toothed grooves that mesh with the rack. When the button is pressed, the rack disengages from the toothed groove, and the first clamp 201 can slide relative to the second clamp 202 and the third clamp 203 to adjust the inner diameter of the clamping space, thereby adapting to different gears. The locking block 105 is used to selectively abut against or release the gear adjustment part of the first clamp 201 by rotation. In the locked state, the side wall of the locking block 105 abuts against the button to restrict its pressing, so that the gear cannot be adjusted. In the unlocked state, the locking block 105 rotates open, and the side wall separates from the button to allow it to be pressed, thereby realizing the gear adjustment function. This mechanical locking structure of the locking block and the button ensures the high stability and anti-theft performance of the clamp after locking.

[0026] In order to reliably install the entire clamp onto the vehicle body or other external carrier, the clamp also includes a second fastening screw 3. The second fastening screw 3 is used to fix the clamping mechanism 2 to the external carrier. Specifically, the second fastening screw 3 can pass through the reserved mounting hole on the clamping mechanism 2 and achieve a firm fixation by means of threaded connection.

[0027] To achieve clear locking and unlocking operations, the lock block 105 can rotate 90 degrees under the drive of the lock cylinder 102, so as to quickly switch between the locked and unlocked positions. Users can complete the locking or unlocking action by turning the key 101 a quarter turn, making the operation intuitive and convenient.

[0028] To achieve multi-position adjustment, the dimensions and sliding stroke of the first pipe clamp 201, the second pipe clamp 202, and the third pipe clamp 203 have been precisely designed to accommodate pipes with diameters ranging from 1.2 to 2.0 inches. Within this range, through the engagement of the rack and pinion, nine precise positions can be formed: 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, and 2.0 inches, meeting the clamping requirements for various pipe sizes.

[0029] To improve durability and clamping reliability, the first pipe clamp 201, the second pipe clamp 202, the third pipe clamp 203, and the iron plate 206 are all made of high-strength metal materials, such as steel or aluminum alloy, to ensure that the structure remains stable when clamping heavy objects or in a vibrating environment. The first soft rubber 204 and the second soft rubber 205 are preferably wear-resistant and elastic rubber or polyurethane materials to extend service life and provide better cushioning effect.

[0030] To further enhance anti-theft performance, the lock cylinder 102 adopts an anti-theft lock cylinder with a complex pin tumbler structure, making it extremely difficult for non-original keys 101 to open it. The connection between the lock block protective cover 103 and the lock cylinder cover 104 is sealed with a waterproof sealing ring to prevent rainwater or dust from entering the lock cylinder and causing corrosion or jamming.

[0031] To help users identify the current gear, the outer surface of the first clamp 201 is engraved with a scale line corresponding to the gear. Meanwhile, an indicator mark is set on the edge of the second clamp 202 or the third clamp 203. By observing the alignment of the indicator mark with the scale line, the user can quickly and accurately adjust to the desired gear.

[0032] Working principle: When this equipment is used, the main body of the equipment consists of an adjustment mechanism 1 and a clamping mechanism 2. The entire equipment is fixedly connected to the vehicle body by the second fastening screw 3. When the lateral width of the lock block 105 is adjusted by the adjusting mechanism 1, the key 101 is paired with the lock cylinder 102, pressing the lock block protective cover 103 onto the lock cylinder cover 104. By turning the key 101, the lock cylinder 102 is rotated by the key 101, causing the lock block 105 to rotate 90°, thus reducing the lateral width of the lock block 105. This allows the button and teeth on the first clamp 201 inside the clamping mechanism 2 to be pressed, thereby allowing the first clamp 201 to engage with the second clamp 202 and the third clamp 204. The pipe clamp 203 can be unlocked. After unlocking the second pipe clamp 202 and the third pipe clamp 203, the gear can be adjusted. The second pipe clamp 202 and the third pipe clamp 203 cooperate with the first pipe clamp 201 to clamp securely. At the same time, the first soft rubber 204 is fixedly connected inside the first pipe clamp 201. The second pipe clamp 202 and the third pipe clamp 203 are connected by the first fastening screw 207 through the iron plate 206. The second soft rubber 205 is fixedly connected inside the second pipe clamp 202 and the third pipe clamp 203. This equipment is suitable for vehicles with pipe diameters of 1.2-2.0 inches, and has 9 gears: 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 and 2.0 inches. It also features a locking function and a gear adjustment function.
