Description

Technical field

The utility model relates to a cylinder wrench, which is used to tighten or loosen the clamping nuts placed on the hubs of motor vehicles.

The utility model relates, in particular, to the cylinder wrench used to tighten or loosen the clamping nuts connecting the hub to the rims on motor vehicles.

Prior art

Balloon wrenches are used to tighten or loosen the clamping nuts that connect the hub to the rims on motor vehicles. The handle of the balloon wrench has a cylindrical shape. The head of the cylinder wrench has a hexagonal configuration corresponding to the outer part, the wheel nut, and is stamped by pressing. The area covering the head of the balloon key and the handle of the balloon key is bent at a certain angle for ergonomic use and a knee is formed. The purpose of the knee is to ensure the comfortable use of the balloon wrench when turning. When you want to use the balloon wrench, the user, first of all, secures the head of the balloon wrench on the outside of the clamping nut. Then, firmly holding the end of the handle of the balloon wrench, he turns the balloon wrench, applying torque; and thus either tightens or loosens the nut with a balloon wrench according to the intended purpose.

In the prior art, it is necessary to apply additional torque to tighten or loosen the nuts, since the balloon wrenches are short. And this presents a difficulty for users when using a balloon key. To overcome this drawback, balloon keys are made up of inserted parts, and an extension of the gripping surface is achieved by lengthening this part. The assembly process for these parts is problematic; disassembling these parts is associated with hard work, and serious difficulties are experienced.

In the prior art, the length of the grip surface of the balloon keys should be small, so that they do not take up too much space in the place of transportation of goods by vehicle. However, during use, additional torque must be applied to tighten or loosen. To prevent this, an extension of the grip surface of the balloon keys is provided. For such an extension operation, on the other hand, parts that do not fit into vehicles are required. These parts take up extra space inside vehicles when the balloon keys are not in use.

One of the applications known in the art is described in application number TR 200402830, where the hexagonal socket of the balloon keys forms a cylindrical pull, with the star shaped in cross section. However, in this application the applied torque is great because the handle of the balloon wrench is short.

In the application under the number US 6662688, that is, another application in the art, when using balloon keys requires a large number of parts. And this means that in cases where the balloon keys are not used, an additional place is taken in vehicles.

Another application known in the art, on the other hand, is application under the number US 4819523; in this application, a large number of parts are required to carry out an operation of tightening or loosening the nuts.

In order to influence this situation in the art, it becomes apparent that another balloon wrench must be provided. This utility model was introduced to overcome the aforementioned disadvantages.

Utility Model Purpose

The purpose of the utility model in relation to the prior art is to produce an elongated balloon wrench, which is made by connecting the drawbar to the balloon wrench, which is designed to be compatible with the drawbar.

Another purpose of the utility model is to provide ease of use by lengthening the cylinder key by connecting the drawbar to the cylinder key.

Another purpose of the utility model is to use the drawbar ring as a handle.

The purpose of the utility model is to ensure that the user works well with the wheel wrenches by applying less torque, despite the fact that the wheel wrenches used to tighten or loosen the clamping nuts connecting the hub to the rims on motor vehicles are small in length. The extension operation, which ensures the extension of the cylinder key only when it is used, is carried out using a tow bar placed on vehicles. The amount of torque required to tighten and loosen the nuts is reduced in cases where a wrench is used that has been lengthened by means of a drawbar.

Another purpose of the utility model is to prevent occupation of extra space with balloon keys when not in use. Since the operation of lengthening the balloon keys is carried out by means of an element located on the vehicles, the spatial losses caused by the balloon keys will be eliminated in cases where it is not necessary to use the balloon keys. And this will provide users with free space inside vehicles.

In accordance with this utility model, the length of the balloon key may increase and return to its standard position again. The thread is carried out on the gripping surface located on the handle of the balloon wrench, according to the thread on the traction bars. Traction bars, which should be on vehicles, will be connected to such serrated side surfaces to ensure elongation of the balloon key; and the torque value needed to tighten or loosen the clamping nuts will be less than in the current situation in the art.

Since there is only one part, there is no need for the operation of assembling the parts of the cylinder keys with one another, as in the prior art. Therefore, problems caused by such an assembly operation are eliminated. Avoiding the loss of time spent on the above assembly operation also provides users with another advantage.

The function of the drawbar providing elongation of the balloon key is to act as a gripping surface where the user holds the balloon key and to provide an increase in the length of the balloon key. There is a round handle on the cylinder keys to facilitate the grip of the drawbar. In addition, in the prior art, this design prevents accidents occurring in the event of a cylinder key slipping out of the user's hands. To achieve the above objectives, the utility model offers a balloon wrench used to tighten and loosen the threads connecting the hub to the rims of motor vehicles; comprising a handle of a balloon key, a head of a balloon key and an elbow, characterized in that the connecting section is formed by narrowing the end of said handle of a balloon key; a thread cut in the inner portion of the specified section, according to the thread placed on the drawbar.

Detailed description of utility model

This detailed description describes preferred embodiments of a tapered and threaded end of a balloon key as an object of a utility model, the description being provided only for a better understanding of the subject of discussion and does not create any restriction effect.

The utility model, which can be seen in FIG. 1, relates to a balloon key, (10) used to tighten and loosen the threads connecting the hub to the rims of motor vehicles, including the handle (11) of the balloon key, the head of the balloon key (12), and knee (13); and characterized in that the connecting section (30) was formed by narrowing the end of said handle (11) of the balloon key; the thread (31) of the balloon wrench is cut in the inner section of the indicated section (30) in accordance with the thread (21) of the drawbar located on the drawbar (20).

The connecting section (30), denoted as A in figure 1, is formed by narrowing the end of the handle (11) of the balloon wrench, which has a cylindrical structure. As a result of the narrowing of this end, the connecting section (30) has a smaller diameter than the specified handle (11). The purpose of narrowing the connecting section (30) is to enable threading (31) in accordance with the thread (21) of the drawbar. The thread (31) of the balloon wrench is cut into the inner portion of the connecting section (30) so as to fit the thread (21) of the drawbar.

Figure 2 is a general view of a preferred embodiment of a balloon wrench (10), which was narrowed at the end and threaded as an object of a utility model. Traction beam (20) and handle of a balloon key; (11) are connected to each other by turning the thread (21) of the drawbar and the thread (31) of the balloon wrench. The connecting section (30) has a design that allows you to firmly insert into each other the traction beam (20) and the handle of the balloon key (10). By connecting the drawbar (20) to the end of the handle (11) of the balloon key, the balloon key is extended. Thanks to the elongated balloon wrench (10), less torque is required for its use.

The thread (31) of the balloon wrench has a design that allows the drawbar to enter the connecting section (30) and lock onto the handle of the balloon wrench.

The connecting section (30) is located at the end of the handle (11) of the balloon wrench; it has a smaller diameter than the diameter of the handle of a balloon wrench; and it has a design that provides a firm grip on the thread (21) of the drawbar with the thread (31) of the balloon wrench.

In other words, the shape of the balloon key has been changed to be able to connect to the drawbar (20) while maintaining the original form of the drawbar (20) used in the prior art. To ensure this, despite the fact that the end of the key (12) remains unchanged, the shape of the other end was made so as to be compatible for connecting the traction beam (20). Therefore, as mentioned above, this working end of the balloon key is narrowed to a size that allows the working end of the drawbar (20) to enter into it, and is threaded on the inner surface. By threading, an inner surface is produced that is compatible with the thread of the drawbar.
