Description

The utility model relates to the construction industry and is intended for driving various fasteners into various materials during construction and installation works.

The prior art (RF patent No. 2242567, 12/20/2004) is known a device that can be used to hammer pointed objects into various objects, containing a multi-stage becoming coaxially placed guide glasses, the head of which is equipped with a punch, and the tail is driven. Each forward-running glass, under the influence of pressure springs located between the glasses, is supported by grooves on movable spherical bearings - balls placed in radial through grooves of the rear glasses. The balls are overlapped by axially arranged glasses having a bore on the side of the gauge with a depth equal to or greater than the diameter of the ball, with a width equal to its diameter. Starting from the tail of the stand, the cups and the springs pressing them are made with successively increasing lengths and decreasing diameters, and the distances between the grooves and bores in the interacting cups are equal to or less than half the length of the free springs compressing them. The assembly of the device begins with a drive cup, which is inserted into the tail glass to failure. A spring is placed in the tail glass, then the middle glass is introduced. Holding the spring in a compressed state, place the balls between the radial grooves and the groove and cover with plugs. In a similar way prepare the middle, head glasses and punch. The device operates as follows. To clog a pointed object, the drive cup of the described device is moved from right to left to support. Under the force of the spring of the tail glass, becoming, consisting of the tail, middle, head glasses and punch, sliding on the spherical surface of the balls, shifts them into the bore. When moving this stand forward, the through radial grooves with the balls of the middle glass will be combined with the groove of the tail glass and the balls of the middle glass, by analogy with the previous case, will be freed from the stationary state. Under the force of the spring of the head glass, the punch is pushed out of it on the spherical surface of the balls of the head glass. To clog the next pointed object, the device is again assembled according to the method described above.

The disadvantages of this device are the complexity of the design, as well as the complexity of the operation of the structure due to the need to reassemble the device before each use (before each clogging of the pointed device).

The technical problem to which the claimed utility model is directed is the development of a simple design of a manual semiautomatic tool for driving various fasteners, ensuring a high speed of the device and, as a result, acceleration of installation work.

The technical result of the patented solution is to increase operational characteristics by simplifying the design of the device, reducing the complexity when operating the device for driving fasteners.

The specified technical result is achieved in a device for driving fasteners, comprising an external hollow body made with the possibility of placing an internal hollow body in it, while the internal body contains a spring-loaded striker and a spring-loaded striker, an opening for passing the striker is made in the lower part of the internal body, and the outer casing includes a spring mounted in its cavity and a cock, mounted movably on the outer casing, and the cock is also mounted on the inner casing Vision and configured to provide a reciprocating movement of the striker to strike the firing pin, wherein the reciprocating movement of the striker is limited.

The external hollow body of the device (repeat) may be made of metal or plastic. One side of the spring is fixed in the upper part of the cavity of the outer casing.

In the outer casing (in the casing wall), a spring can be installed for springing the cock in order to guarantee automatic reset of the cock in its original position (impact position of the hammer), which leads to the absence of the need to reassemble (adjust) the device before each clogging procedure, and thus provides a reduction in time by one mounting point, which leads to an additional increase in the operational characteristics of the device. The drummer contains a pin (pin) for interacting with the platoon during the platoon of the drummer. The drummer can also be made with two pins located on opposite sides.

The cock contains a hole (groove) to ensure movement of the pin along it, made on the inner case, when the cock moves. The groove has an oval shape and large size, allowing the pin to slip to its initial position upon repeated exposure to muscular strength, which allows the cock to engage the hammer pin and repeat the entire process of driving the fastener again.

When a striker with two pins is used in the design of the device, the platoon is Y-shaped for its interaction with the pins of the striker and to ensure a more uniform load distribution during the platoon, which increases the reliability of the platoon mechanism, and further improves the operational characteristics of the device.

The inner casing is connected to the outer casing by a platoon, one side of which is fixed by a movable connection to the outer casing, and the second is movably fixed on the inner casing when the pin is placed in the groove.

The outer hollow body at the top of the outer body may include a hole for accessing a threaded screw. The presence of a hole, as well as a screw and a support plate as part of the inner case, allows you to screw or unscrew a screw with a thread, for example, with a screwdriver, which makes it possible to adjust the position of the support plate and additionally improves the performance of the device due to the possibility of adjusting the tension force of the spring of the hammer.

In the middle part of the cavity of the inner case, elements can be made (for example, protrusions on the inner wall of the cavity of the case), restricting the movement of the striker and, thus, dividing the cavity of the inner case into two compartments: the upper one for placement and movement of the striker and the lower one for placing and moving striking it.

A spring-loaded striker can have a different shape and can be made of various high-density materials, for example, metals.

The lower compartment of the inner case contains a spring-loaded striker.

The firing pin can be centered inside the inner body with elements that limit the movement of the hammer.

The firing pin can be movably fixed in the cavity of the inner body. For this, the striker may contain a longitudinal groove (or a pair of oppositely located grooves) in its upper part, and a protrusion / pair of protrusions is formed inside the cavity of the inner case for its / their placement in the groove / grooves. For example, the hammer may be a rod with a helical surface in its upper part. The helical surface contains grooves (acting as grooves). For placement in them (in the initial position) a pair of protrusions located in the cavity of the inner case.

The tip of the striker rod can be flat for efficient hammering of nails or have a cruciform shape under a cruciform slot for driving a dowel-nail or contain any other shape depending on the object to be hammered.

To limit the reciprocating movement of the striker through the hole in the lower part of the inner case, a limiter can be made on the striker rod (for example, in the form of a protrusion). Thus, the limiter abuts against the protrusions of the lower part of the inner case, which thereby prevent the striker from falling out of the inner case.

In another embodiment, to limit the reciprocating movement of the striker in the device, a striker is used with a stopper made on its rod, as well as a cover, for installation on the outside of the lower part of the device’s inner case. In this case, the cover is connected to the housing by means of a threaded connection and has an opening for the passage of the striker rod. In addition, the hole in the lower part of the inner case of the device does not interfere with the passage of the striker stopper, however, the striker stopper rests against the cover body when the rod passes through the hole in the cover. The implementation of the device according to this option allows the replacement of the strikers, depending on the type of slots of the fastener and to select the strikers with a suitable slot tip. Thus, this provides an additional increase in the operational characteristics of the device due to the expansion of the functional characteristics of the device due to the possibility of using the device for efficient and convenient hammering of nails (the cap of which does not have a slot) and dowel nails (the cap of which has a cross slot).

The simplicity of the design of the device helps to increase the speed of the device due to the minimum number of operations performed by the device in a single cycle of clogging of the fastener, and also eliminates the need for reassembly when clogging each individual fastener. This leads to a reduction in installation time, requiring clogging of the fasteners, and, as a result, provides an increase in the operational characteristics of the device.

The absence of the need for reassembly when driving each individual fastener significantly reduces the complexity of the operation of the device, on the one hand, and on the other hand, it accelerates installation work, which leads to an increase in the operational characteristics of the device.

A device for driving various types of fasteners contains an outer casing (cocking handle) 1 and an inner casing 2. A return spring 3 is installed in the cavity of the outer casing 1, and a hole 4 is made in the upper part of the casing 4. A cocking spring 5 and a charging cock are located in the lower part of the outer casing 1 6. The cock 6 is connected to the outer casing by a movable joint 7. In addition, the cock has an oval groove (groove) 8 for accommodating a pin 9 located on the wall of the inner housing 2. The return spring 3 is attached to eshnemu 1 body. A hole with a thread is made in the upper part of the inner case for screwing a screw 10 into it, so that the screw shaft can enter the cavity of the inner case. In the cavity of the inner casing 2, a spring 12 of the hammer 13 is mounted. On the upper side of the spring 12, a support plate 11 is fixed so that when the screw 10 is screwed into the cavity of the inner housing 2, the shaft of the screw 10 abuts the plate 11. The spring of the hammer 12 is connected to the hammer 13. Pin 14 is located on the drummer. In the middle part of the device’s inner case 2 there are projections 15. The spring of the hammer 16 and hammer 17 are located in the lower part of the internal housing 2. There are grooves (grooves) 18 on the upper part of the hammer, on its screw surface, and lower cha minute protuberances 19. The striker has a cross-shaped tip 20 under the cruciform slot dowel-nail. A cover 22 is screwed onto the lower part of the inner case due to a threaded connection. In the cover 22 there is an opening for the passage of the rod of the striker 17, however, preventing the passage of the protrusions 19 located on the rod of the striker 17.

The device operates as follows. An anchor nail or other fastener is inserted into the drilled hole in the wall. The tip of the striker of the cross-shaped type 17 is inserted into the dowel-nail head with a cross-shaped slot. The forces of one hand create muscle pressure, which compresses the return spring 3. As soon as the immersion of the striker 17 begins inside the device, the striker 17, made in the form of a rod with a screw surface located in the upper part of the rod, rotates around its axis counterclockwise approximately 90 ° degrees due to the fact that the protrusions of the middle part of the inner case 15 are moved along the grooves of the screw surfaces 18 (striking grooves). As a result of a 90 ° rotation, the cross-shaped tip of the striker enters the dowel-nail slots, which allows more reliable fixing of the dowel-nail on the striker tip and eliminates the need for additional rotation of the entire device for the tip to enter the dowel-nail slots. The firing pin 17 together with the platoon mechanism sets the firing pin 13 in motion and thereby finally presses the nail into the dowel. The influence of muscle force drives the platoon mechanism, namely: the outer part of the housing 1 compresses the spring 5 of the cock and moves the cock 6, which, on the basis of the lever, abuts the pin 14 of the hammer 13, thereby lifting the hammer 13 and compressing the spring of the hammer 12. A screw with a thread 10, by adjusting the position of the support plate 11 (when screwing the screw into the cavity of the inner case, the screw shaft presses on the plate located on the spring, thereby shifting the plate down) and allows you to adjust the impact force of the striker 17 due to m adjusting spring force impactor 12 by changing the position of the support plate 11. The opening in the top of the outer casing 4, is designed to access, for example, a screwdriver to screw 10 threaded for its screwing and unscrewing. The spring of the striker 16 is compressed until the platoon mechanism continues to cock the striker 6. Then the trigger is triggered and the striker 13 collides with the striker 17, which in turn clogs the dowel-nail fastener with a do-it-yourself. When releasing pressure on the outer casing 1, the spring of the cock 5 is unclenched and the cock 6 returns to its original position. Due to the large size of the groove 8, upon repeated exposure to muscular force, the pin 9 slips into its initial position, which allows the cock 6 to engage the hammer 13 and repeat the whole process again. In the middle part of the inner case there are protrusions 15 that allow you to block the hammer after the trigger is triggered. The reciprocating movement of the striker 17 inside the inner housing 2 is limited by a lid with a thread 22 mounted on the lower side of the inner housing 2, since the protrusions 19 on the stem of the striker 17 abut against the lid housing. Using the cover 22 as part of the device allows you to replace the striker 17 and use the striker with a tip suitable for any type of fasteners. In another embodiment, the device may be made without a threaded cover. However, in this case, to limit the reciprocating movement of the striker in the lower part of the inner body, protrusions 21 are made. Thus, with the reciprocating movement of the striker 17, the protrusions of the striker 19 abut against the protrusions 21 of the body 2, which prevents the striker 17 from falling out of the device. In this embodiment, there is no possibility of changing the striker.

The platoon mechanism allows you to use the utility model repeatedly without the need for reassembling the device and preparing for a single clogging, which significantly reduces the time by one attachment point.

The grooves 18, the protrusions of the middle part of the inner housing 15 and the possibility of axial rotation of the striker 17 can reliably and quickly fix the splines of the striker 20 with a fastener.

A screw with a thread 10 allows you to adjust the impact force, and the hole in the upper part of the handle adjusts the position of the support plate 11, therefore, adjusting the compression force of the spring, thereby reducing the number of impacts per attachment point and thereby increasing the operational characteristics of the device.
