Description

TECHNICAL FIELD

[0001] The utility model relates to a broken glass ball launching device technical field, specifically to a broken glass device. BACKGROUND

[0002] The broken glass device (or called broken glass device, broken glass ball launcher) is a special equipment for throwing broken glass ball (or high drilling ball) for long-range broken glass, which is widely used in the field of fire fighting and rescue. At present, the structure of the broken glass device is various, and the use mode is various. For example, a throwing type broken glass system disclosed in Chinese patent CN114209996B can be installed on a high spray vehicle for use; a manual activation type broken glass device disclosed in Chinese patent CN221579515U can be used manually; a pneumatic type broken glass ball launching mechanism disclosed in Chinese patent CN211893653U can be used on a drone.

[0003] The pneumatic type broken glass ball launching mechanism disclosed in Chinese patent CN211893653U specifically comprises a power chamber, a blocking mechanism and a locking mechanism, etc. The power chamber and the blocking mechanism are mutually adapted, the blocking mechanism is movably arranged at one end of the power chamber, and is used for blocking and starting the power chamber. The locking mechanism and the blocking mechanism are mutually adapted, and are used for locking and unlocking the blocking mechanism. When the locking mechanism locks the blocking mechanism, the power chamber is closed, and the air pressure in the power chamber can be increased and reach the required pressure for throwing the broken glass ball. When it is needed to throw the broken glass ball, the blocking mechanism is unlocked by the locking mechanism, and moves and releases the high-pressure gas in the power chamber under the action of the air pressure in the power chamber, so that the high-pressure gas acts on the broken glass ball in the launching channel, and the broken glass ball can be thrown out by the air pressure.

[0004] In the existing products, the locking mechanism usually comprises a locking rod matched with the blocking mechanism, the power module is in transmission connection with the transmission rod, and the transmission rod is in transmission connection with the locking rod, so that the power module can drive the locking rod to perform unlocking action through the lever principle. The existing transmission rod is usually constrained in the bracket in a lifting manner, the bracket is usually made of aluminum alloy or steel material, and at the same time, the transmission rod is usually made of aluminum alloy or steel material. When in use, the power module drives the transmission rod to descend, so as to drive the locking rod to unlock the blocking mechanism. However, it is found in actual application that the friction between the transmission rod and the bracket is large, which is not only not conducive to the smoother action of the transmission rod, but also the transmission rod is easily worn out. On the one hand, the cooperation precision of the transmission rod and the bracket is reduced, which is not conducive to high-precision transmission, and the phenomenon that the transmission rod cannot be in transmission connection with the locking rod exists. On the other hand, the transmission rod needs to be replaced after excessive wear, which shortens the replacement cycle of the transmission rod and increases the subsequent maintenance cost, which needs to be solved urgently. SUMMARY

[0005] This utility model first solves the above-mentioned technical problems by providing a transmission mechanism that can reduce friction and protect the transmission rod, which is beneficial for the stable and reliable use of the glass breaking device and reduces subsequent maintenance costs. The main concept is as follows:

The bracket has a copper sleeve with a guide hole adapted to the transmission rod. The transmission rod is inserted into the guide hole of the copper sleeve, forming a sliding pair with the copper sleeve. The power module drives the transmission rod to move up and down. In this design, by configuring the copper sleeve and inserting the transmission rod into the guide hole of the copper sleeve, the copper sleeve can directly contact the transmission rod and also guide the movement of the transmission rod. This effectively reduces the friction between the transmission rod and the bracket, making the movement of the transmission rod smoother and less prone to wear. On the one hand, it helps to extend the service life of the transmission rod, increase the maintenance and replacement cycle of the transmission rod, and thus reduce subsequent maintenance costs. On the other hand, it effectively ensures the movement accuracy of the transmission rod, ensuring that the transmission rod can always be connected to the locking rod, making the transmission more precise and stable, thereby contributing to a more stable and reliable performance of the glass-breaking device.

[0009] Furthermore, the bracket is also provided with a guide cylinder, and the mounting hole is constructed inside the guide cylinder. The copper sleeve is installed in the guide cylinder through the mounting hole. By configuring the guide cylinder, it is not only easier to process and manufacture the mounting hole inside the guide cylinder, but it can also effectively reduce the space occupied in the glass breaking device, which is conducive to a more compact structure of the glass breaking device.

In order to transmit power between the connecting rod and the transmission rod through the cooperation of the restraint portion and the connecting shaft, it is not only convenient for transmission, but also convenient for assembly.

[0012] Preferably, the restraint portion is a strip-shaped bayonet constructed at the end of the connecting rod, and the connecting shaft is inserted into the strip-shaped bayonet. Not only is it convenient to assemble, but also the strip-shaped bayonet and the connecting shaft can be used to drive the transmission rod to lift.

Therefore, the limiting groove can be used to limit the connecting shaft, prevent the connecting shaft from rotating relative to the copper sleeve, and further prevent the transmission rod from rotating relative to the copper sleeve, so that the trigger head at the lower end of the transmission rod always corresponds to the locking rod, so as to always keep stable transmission cooperation with the locking rod.

When the transmission rod moves downward, the trigger head can press one end of the locking rod to lift the other end of the locking rod to achieve the purpose of unlocking; during the resetting process of the transmission rod, if interference occurs between the trigger head and the locking rod, the trigger head can automatically rotate relative to the transmission rod under the action of the pressing force, so that the transmission rod can smoothly rise, and the trigger head can automatically reset under the action of the torsional spring after passing through the locking rod, thereby effectively solving the problem that the trigger head is stuck due to interference with the locking rod during the resetting process of the transmission rod, and the stability and reliability can be improved.

In the embodiment, the transmission rod 3 can be directly connected with the locking rod 4, or can not be connected. One end of the locking rod 4 is arranged below the transmission rod 3 and can be pressed downward by the transmission rod 3.

[0037] As shown in the figure, Figure 1 In the embodiment, the support 51 is provided with a copper sleeve 52, the copper sleeve 52 is constructed with a guide hole 53 matched with the transmission rod 3, the transmission rod 3 is inserted into the guide hole 53 of the copper sleeve 52 and forms a moving pair with the copper sleeve 52.

Figure 1 In implementation, the mounting hole 55 can be a blind hole or a stepped hole.Figure 1 As shown in the figure, the copper sleeve 52 can be positioned by the stepped hole, which not only makes the assembly of the copper sleeve 52 more convenient, but also makes the high-precision assembly of the copper sleeve 52 more convenient.

[0039] In order to improve the stability of the transmission rod 3, the copper sleeve 52 should have a certain length in implementation. Therefore, in order to facilitate the installation of the copper sleeve 52, the bracket 51 is also provided with a guide cylinder 54 in implementation, and the mounting hole 55 can be constructed in the guide cylinder 54, as shown in the figure. Figure 1 As shown in the figure, the copper sleeve 52 can be installed in the guide cylinder 54 through the mounting hole 55, which not only facilitates the processing and manufacturing of the mounting hole 55 in the guide cylinder 54, but also effectively reduces the space occupied in the glass breaking device, which is beneficial to the more compact structure of the glass breaking device.

In the embodiment, the power module 1 is in transmission connection with the connecting rod 2, so as to drive the connecting rod 2 to swing by using the power module 1, and the swinging of the connecting rod 2 can drive the transmission rod 3 to lift, so that in the embodiment, only the connecting rod 2 needs to be arranged between the power module 1 and the transmission rod 3 to achieve the purpose of driving the transmission rod 3 to lift, thereby effectively simplifying the transmission mechanism 14 and reducing the space occupied by the entire transmission mechanism 14, which is beneficial to the smaller size and more compact structure of the entire glass breaking device.

[0041] In implementation, the constraint part has various implementation modes, for example, the constraint part can be a slot hole constructed in the connecting rod 2, and the connecting shaft 32 is inserted in the slot hole, which not only facilitates assembly, but also drives the transmission rod 3 to lift through the cooperation of the slot hole and the connecting shaft 32, in this process, the connecting rod 2 can not only move relative to the transmission rod 3, but also rotate relative to the transmission rod 3, so as to avoid interference during transmission and achieve smooth transmission. In the preferred embodiment provided in the embodiment, the constraint part can be a strip-shaped bayonet 21 constructed at the end of the connecting rod 2, as shown in the figure. Figure 1 The connecting shaft 32 is inserted in the strip-shaped bayonet 21, which not only achieves the same technical effect, but also facilitates installation and disassembly.

[0042] In implementation, the top of the transmission rod 3 is provided with a connecting shaft 32, as shown in the figure. Figure 1 and Figure 2As shown, the connecting shaft 32 can be perpendicular to the length direction of the transmission rod 3, and the connecting shaft 32 is sleeved on the constraint part, so that the power is transmitted between the connecting rod 2 and the transmission rod 3 through the cooperation of the constraint part and the connecting shaft 32, which is not only convenient for transmission, but also convenient for assembly. In the implementation, the connecting shaft 32 can be fixedly installed on the transmission rod 3, or rotatably arranged on the transmission rod 3. In a further embodiment, the connecting shaft 32 is also sleeved with a roller 33, as shown in Figure 1 and Figure 2 As shown, the roller 33 can rotate relative to the transmission rod 3, and the roller 33 is used to contact the constraint part, so that rolling friction can be realized between the connecting rod 2 and the transmission rod 3 during transmission, thereby greatly reducing the friction during transmission, making the transmission process smoother and more labor-saving. In the present embodiment, the roller 33 adopts a bearing, as shown in Figure 1 and Figure 2 which is conducive to smoother and more labor-saving transmission.

[0043] In order to facilitate the assembly of the connecting shaft 32, in the present embodiment, the top of the transmission rod 3 is provided with two opposite lugs 31, as shown in Figure 1 and Figure 2 The lug 31 is provided with a through hole, and the connecting shaft 32 can be installed on the two lugs 31 through the through hole, which is not only convenient for assembly, but also after assembly, the end of the connecting rod 2 can be constrained between the two lugs 31, thereby effectively preventing the connecting rod 2 from coming out of the connecting shaft 32, and ensuring the stability and reliability of the transmission connection.

[0044] In the implementation, the power module 1 can adopt a motor, and in the present embodiment, the power module 1 adopts a steering gear, which is conducive to making the entire glass breaking device smaller and more compact in structure.

[0045] In the present embodiment, the connecting rod 2 can be an existing transmission rod 3, and in the preferred embodiment provided in the present embodiment, the connecting rod 2 adopts a Z-shaped structure, as shown in Figure 1 , Figure 4 and Figure 5 which makes the power module 1 can be arranged at a position closer to the transmission rod 3, so that the transmission mechanism 14 is more compact and occupies less space, thereby facilitating the entire glass breaking device to be smaller and more compact in structure.

[0046] In the implementation, the connecting rod 2 can be directly connected with the power module 1, and in the preferred embodiment provided in the present embodiment, a flange plate 12 is further included, as shown in Figure 3 The flange plate 12 is provided with at least two flange holes 13 in the circumferential direction, and the power module 1 is in transmission connection with the flange plate 12 for driving the flange plate 12 to rotate, for example, the flange plate 12 can be connected to the output shaft 11 of the power module 1 (such as a steering gear) through fasteners. One end of the connecting rod 2 is provided with a connecting disc 22, as shown inFigures 3-5 As shown, the circumferential direction of the connecting disc 22 is configured with connecting holes 23 matching the flange holes 13.

In assembly, the connecting disc 22 can be fixed to the flange plate 12 through fasteners matching the connecting holes 23 and the flange holes 13 for installation and disassembly. By configuring the flange holes 13 or the connecting holes 23 as arc-shaped strip holes and arranging both the flange holes 13 and the connecting holes 23 in the circumferential direction, the connecting disc 22 can rotate relative to the flange plate 12 in assembly, so that the pitch angle of the connecting rod 2 can be adjusted by rotating the connecting disc 22, thereby effectively adjusting the initial height position of the transmission rod 3, which is not only very convenient, but also can solve the transmission error caused by manufacturing and assembly errors, and is beneficial to realize higher precision transmission. Embodiment

[0047] To ensure that the transmission rod 3 and the locking rod 4 can stably realize transmission cooperation, the main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that the support 51 of the present embodiment is also provided with a limiting groove 56 arranged along the length direction of the copper sleeve 52, and the connecting shaft 32 is limited and constrained in the limiting groove 56, as shown in Figure 6 Thus, the limiting groove 56 can be used to limit the connecting shaft 32, prevent the connecting shaft 32 from rotating relative to the copper sleeve 52, and further prevent the transmission rod 3 from rotating relative to the copper sleeve 52, so that the trigger head 34 at the lower end of the transmission rod 3 always corresponds to the locking rod 4, so as to always maintain stable transmission cooperation with the locking rod 4.

[0048] In one embodiment, a plurality of limiting columns can be configured on the support 51 to form the limiting groove 56 between two limiting columns; in another embodiment, the limiting groove 56 can be directly configured on the guide cylinder 54, as shown in Figure 6

[0049] In implementation, the end of the connecting shaft 32 can be inserted into the limiting groove 56 after passing through the ear piece 31, as shown in Figure 6 and Figure 7 At the same time, the connecting shaft 32 in the limiting groove 56 can also be provided with a roller 33 to reduce the friction between the connecting shaft 32 and the limiting groove 56. In implementation, the roller 33 can also preferentially adopt a bearing, as shown in Figure 7 Embodiment

[0050] To facilitate the quick reset of the locking rod 4, the main difference between the present embodiment 3 and the above-mentioned embodiment 1 or embodiment 2 is that the locking rod 4 of the present embodiment is configured with a hinge hole 41, which is a strip hole, as shown in​​Figure 8 As shown, the locking rod 4 is rotatably mounted on the bracket 51 through the hinge hole 41, and one end of the locking rod 4 is adapted to the transmission rod 3, as shown. Figure 8 As shown, the other end is provided with a locking head 42 for locking the blocking mechanism 7; a tension spring 43 is also connected between the locking rod 4 and the bracket 51, and the tension spring 43 is used to press the locking rod 4 down toward the first end where the locking head 42 is provided, such as... Figure 8 As shown.

[0051] In this embodiment, the locking rod 4 and the transmission rod 3 are not directly connected, such as... Figure 8 As shown, by configuring the hinge hole 41 as a slot, the locking rod 4 can both rotate and move relative to the bracket 51. This allows one end of the locking rod 4 to move below the transmission rod 3 so that it can be pressed downwards by the transmission rod 3, thus enabling the transmission rod 3 to form a transmission engagement with the locking rod 4. Alternatively, one end of the locking rod 4 can also disengage from below the transmission rod 3. In this case, the locking rod 4 cannot be pressed downwards by the transmission rod 3, allowing the locking rod 4 to reset more quickly after triggering without being interfered with by the transmission mechanism 14.

[0052] To prevent the transmission rod 3 from interfering with the locking rod 4 and jamming during the reset process, in a further embodiment, a trigger head 34 is rotatably provided at the lower end of the transmission rod 3, such as... Figure 8 and Figure 9 As shown, the transmission rod 3 is also provided with a limiting part 35, which is located above the trigger head 34, as shown. Figure 8 and Figure 9 As shown, a torsion spring is provided between the trigger head 34 and the transmission rod 3. Initially, the trigger head 34 abuts against the limiting part 35 upward under the action of the torsion spring, as shown. Figure 8 and Figure 9 As shown, the trigger head 34 protrudes from the side wall of the transmission rod 3 to cooperate with the locking rod 4. In use, when the transmission rod 3 moves downwards, the trigger head 34 can press one end of the locking rod 4, thereby lifting the other end of the locking rod 4 and unlocking it. During the upward reset process of the transmission rod 3, if interference occurs between the trigger head 34 and the locking rod 4, the trigger head 34 can rotate downwards relative to the transmission rod 3 under the pressure, allowing the transmission rod 3 to rise smoothly. Furthermore, after passing the locking rod 4, the trigger head 34 can automatically reset under the action of a torsion spring, effectively solving the problem of the trigger head 34 jamming due to interference with the locking rod 4 during the reset process of the transmission rod 3, thus improving stability and reliability.

[0053] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
