DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a thin cylinder self-locking clamping device, comprising:

[0025] A cylinder body 3, wherein a telescopic rod 31 is arranged inside the cylinder body 3, and a self-locking mechanism 4 is detachably connected to one side of a front end cover of the cylinder body 3;

[0026] The self-locking mechanism 4 includes a locking plate 41, both sides of which are provided with through holes 42 for the telescopic rod 31 to be slidably inserted, the inner cavity of the locking plate 41 is fixedly connected with three groups of limit blocks 43 at equal angles, and connecting pipes 44 are connected between two adjacent groups of limit blocks 43, and a boost pipe 45 is connected to the middle of the outer side of one group of connecting pipes 44, and a side groove 46 is opened on one side of the three groups of limit blocks 43, and a plug hole 47 and an adjustment hole 48 are opened at the bottom of the side groove 46, and the adjustment hole 48 is connected with the two groups of connecting pipes 44, and a spring 411 is fixedly connected to the bottom of the adjustment hole 48, and one end of the spring 411 is in contact with a piston rod 410, and one end of the piston rod 410 is fixedly connected to a tooth plate 49, and the outer side of the telescopic rod 31 is provided with tooth grooves 6 at equal angles, and the teeth on the tooth plate 49 match the teeth in the tooth groove 6.

[0027] Three sets of fixing bolts 7 are threadedly connected to one side of the front end cover of the cylinder body 3, and the locking plate 41 is bolted to the front end cover of the cylinder body 3 through the three sets of fixing bolts 7. The fixing bolts 7 are used to facilitate the installation of the self-locking mechanism 4 on the front end cover of the cylinder body 3, and the disassembly and assembly are convenient, and the self-locking mechanism 4 is easy to maintain.

[0028] It also includes a limit plate 2, one side of the locking plate 41 abuts against one side of the limit plate 2, and a clamping mechanism 5 is provided on the other side of the limit plate 2. One end of the telescopic rod 31 is hinged to the clamping mechanism 5. The limit plate 2 is used to facilitate positioning of the cylinder body 3 and the limit mechanism, thereby improving the stability of the cylinder body 3 during use and making it easier to install the clamping mechanism 5.

[0029] The clamping mechanism 5 includes a fixed block 51 welded to the lower end of the other side of the limiting plate 2, and connecting rods 52 are hinged on both sides of the fixed block 51, and one end of the telescopic rod 31 is hinged with a fixing pin 54, and one end of the telescopic rod 31 is hinged with a pressure rod 53 through the fixing pin 54, and the middle parts of both sides of the pressure rod 53 are respectively fixedly connected with hinge blocks 56 hinged to two groups of connecting rods 52. When the telescopic rod 31 is extended or retracted, it is hinged to one end of the pressure rod 53 through the fixing pin 54, and the pressure rod 53 is hinged to one end of the connecting rod 52 through the hinge block 56, and the other end of the connecting rod 52 is hinged to both sides of the fixed block 51, so that the pressure rod 53 can be flipped to facilitate clamping of the object and improve the stability of the object during processing.

[0030] A clamping plate 55 is integrally formed at one end of the pressure rod 53, and an anti-skid pad is bonded to one side of the clamping plate 55. A round hole for the telescopic rod 31 to slide and insert is opened on one side of the limit plate 2. The clamping plate 55 increases the contact area with the object, thereby improving the stability of the clamped object. At the same time, the anti-skid pad reduces the rigid contact during clamping, thereby improving the protection effect of the object.

[0031] The device also includes a mounting member 1, which is a right-angle plate, the cylinder body 3 is mounted on the short plate side of the mounting member 1, the limit plate 2 is bolted to the long plate side of the mounting member 1, the mounting member 1 is used to facilitate the installation of the device as a whole, and the mounting member 1 is provided with holes for bolts to penetrate, so that the mounting member 1 can be easily installed at any position. The scope of application is increased.

[0032] An insert rod 412 is welded to one end of the tooth plate 49 away from the piston rod 410, and the insert rod 412 is slidably inserted into the inner cavity of the socket 47. The insert rod 412 improves the stability of the tooth plate 49 driven by the piston rod 410 to be embedded in the tooth groove 6, avoids angular deviation of the tooth plate 49, and improves the efficiency of locking the telescopic rod 31.

[0033] When in use, the mounting member 1 is fixed in a suitable position by connecting bolts. When the telescopic rod 31 of the cylinder body 3 is extended, the telescopic rod 31 drives the clamping plate 55 end of the pressure rod 53 to approach the limit plate 2 through the fixing pin 54, thereby facilitating the clamping of the object. Conversely, the telescopic rod 31 contracts and drives the clamping plate 55 end of the pressure rod 53 away from the limit plate 2, thereby separating from the object. When the telescopic rod 31 is extended and retracted, the pressure-boosting pipe 45 is pressed through the connecting pipe 44 into the adjusting hole 48, and the adjusting hole 48 is adjusted. The pressure at the end of the inner piston plate away from the spring 411 increases, which in turn causes the piston rod 410 to squeeze the spring 411, causing the tooth plate 49 to disengage from the tooth groove 6 of the telescopic rod 31, thereby facilitating the extension and retraction of the telescopic rod 31. Conversely, when there is no pressure increase in the boost pipe 45, the piston rod 410, under the elastic action of the spring 411, causes the tooth plate 49 to fit into the tooth groove 6 of the telescopic rod 31, thereby locking the telescopic rod 31 and preventing the telescopic rod 31 from moving after being extended to a specified length, thereby improving the stability of the clamped object.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
