Between these protrusions is located a hook 18 made on the jumper 15. In the assembled position of the device, the protrusions 16 and 17 are located respectively in the left and right grooves 19 and 20 of the strap 10, and the hook 18 is located in the middle groove 21, which is located between the left and right grooves 19 and 20 of the bar 10. All the tabs you fulfill the functions of the guide elements for moving the strips 10 relative to them, and all the grooves are made elongated in the longitudinal direction of the strap. The bar is installed with the possibility of its movement in the transverse direction of the housing 1.

The jumper 15, also included in the design of the locking unit, is located at the level of the lower wall 22 of the housing 1, and the jumper on three sides is limited by the longitudinal sides 23 and the transverse side 24, forming a socket 25 for said locking unit of the device.

The upper (in Fig. 16) screws 14, the pusher 13 is fixedly mounted on the bar 10, which is moved manually by acting on the pusher 13. For this, the pusher has a corrugated part 26, which is located in the window 27 (Fig. 1, 2) of the housing 1 and protrudes housing surface.

One end of the spring 12 (Fig. 15) is hooked to a hook 28 made on the bar 10, the other end of the spring is hooked to the tooth 18 of the jumper 15 of the housing 1. In this regard, the spring 12 acts as a mechanism for returning the bar 10 from the idle position to the working position when the locking the node is closed and the battery is fixed in position in the laptop case. Each tooth 9 of the strap 10 has a beveled surface that interacts with the beveled surface of the tooth 6 of the battery during the introduction of the battery into the compartment 4 of the housing. Each tooth 8 has a beveled surface that interacts with the beveled surface of the tooth 7 of the battery.

Inside the housing 1 in its compartment 4 (Fig. 16) there are guide protrusions 29 and 30, made integral with the wall of the housing 1. In the assembled position of the device, the protrusions are located in the elongated grooves 31 and 32 of the strap 33 of the device fixing unit. These teeth 8 of the fixing unit are made integral with the bar 33, which is mounted on the guide protrusions 29 and 30 with the possibility of moving the bar relative to these protrusions and relative to the housing in its transverse direction. The bar 33 is fixed with screws 34 located in the grooves 31, 32 and screwed into the threaded holes of the protrusions 29 and 30 so that the bar 33 has the ability to move it in the compartment 4 across the housing.

The strap 33 (Fig. 9, 16) of the fixing unit is fixed in extreme positions by a latch 35, made at the end of the strap 33 along with it. The latch has recesses 36 in the end 37 of the strap, which are located along the strap 33 so that they alternately interact with the conical tooth 38, made integral with the wall of the housing 1 and located inside the compartment 4 (Fig. 11, 12). In the interaction of the tooth 38 is located in one of the recesses 36 of the latch 35.

The latch 35 (Fig. 16) is a flexible, elastic jumper formed by a notch in the bar 33. When interacting with the tooth 38, the jumper bends so that the tooth can enter one of the recesses 36. To move the bar 33 across the housing 1, this bar is connected with the second pusher 39 of the device, and this pusher has a corrugated part 40 protruding above the wall of the housing 1 from its outer side (Fig. 1). The corrugated part 40 of the second pusher 39 of the device is located in the window 41 made in the wall of the housing 1. The latter has a semicircular cutout 42, and the battery at this point has a flange 43 for the convenience of manual engagement of the battery when removing it from the compartment 4 of the housing 1.

The device operates as follows. Check the open state of the second strip 33. Insert the battery under the jumper 25 of the housing (Fig. 9) and slide it into the compartment 4 of the housing by moving from right to left. In this case, the beveled surfaces of the teeth 6 of the battery interact with the beveled surfaces of the teeth 9 of the first strip 10, and this strip moves downward in the image of FIG. 9, the spring 12 is stretched, and after the interaction of the chamfered tooth surfaces, the spring 12 is compressed and the teeth 6 of the battery engage with the teeth 9 of the first bar 10 of the locking assembly of the device. In this position, the latch 35 is moved to the position shown in FIG. 14, in which the second bar 33 moves down and its teeth 8 are engaged with the teeth 7 of the battery. In this position, the teeth of the battery and the teeth of the first and second strips of the battery are firmly and reliably held in the housing 1 in its working position, in which the electrical contacts of the battery are stationary in the housing 1 in the design position. The second bar 33 is fixed from displacement in its lower position (Fig. 14) by positioning the tooth 38 of the housing in the upper recess 36. In this position, due to the elasticity of the latch 35, its jumper, in which the recess 36 is made, is constantly pressed against the tooth 38.

Thus, when introducing the battery into the compartment 4 of the housing 1, the battery is pushed into the compartment 4 and the first bar 10 is shifted to the side, while the spring 12 latches the teeth 6 of the battery (Fig. 14), and then the battery is additionally fixed in the compartment 4 by the second bar 33 by its transfer to the battery lock position.

Remove the battery from the compartment 4 of the housing as follows. The corrugated portion 40 of the pusher 39 (FIG. 12) is moved to a position in which the second bar 33 (FIG. 11) moves to the position shown in FIG. 15. In this case, the tooth 38 leaves the upper recess 36 and enters the lower recess 36 of the latch 35, and the teeth 8 of the second plank 33 are displaced upward relative to the teeth 7 of the battery (Fig. 15). The corrugated portion 26 of the pusher 13 is then moved to the position shown in FIG. 15, and the teeth 6 of the battery with the teeth 9 of the bar 10 are disengaged. To remove the battery from the compartment 4 of the housing, it is seized by the flange 43 (Fig. 1) and removed from the compartment 4 of the housing 1.

The use of the battery fixing unit and the locking unit in the device allows the minimum number of hand movements to quickly and reliably install the battery in the battery case and also quickly remove the battery from the case.
