Description

Technical Field

[0001] The utility model relates to the field of swing batons. Background Art

[0002] Chinese patent document CN218209089U discloses a baton flashlight, comprising a flashlight body, a mounting tube at one end of the flashlight body, at least one telescopic rod arranged in the mounting tube, and a limiting portion for limiting the telescopic rod arranged in the mounting tube, and further discloses that the limiting portion comprises at least two spring leaves, each of which applies a force from the inside to the outside from the center point of the limiting portion; each spring leaf comprises a fixed area, a contact limiting area and a limiting area, the fixed area and the limiting area are arranged at both ends of the spring leaf, the spring leaf is fixed on the inner wall of the mounting tube through the fixed area, and the contact limiting area is arranged between the fixed area and the limiting area; , the diameter at the contact limit area is greater than the diameter at the limiting area; when the spring sheets of the limiting part are unfolded, the diameter at the limiting area is smaller than the inner diameter of the through hole of the innermost telescopic rod, and the diameter at the contact limit area is greater than the inner diameter of the through hole of the innermost telescopic rod; the position of the innermost telescopic rod is limited by the limiting area and the contact limit area to prevent it from being unable to be limited in position; the force applied outward by the spring sheet further applies a limited force to the telescopic rod; when the innermost telescopic rod is retracted, the limited area of ​​the spring sheet enters the through hole of the telescopic rod, and the spring sheet applies a force from the inside to the outside from the center point of the limiting part, thereby limiting the position of the telescopic rod.

[0003] It can be seen that the above-mentioned spring sheet is fixed on the inner wall of the installation tube through the fixing area, the connection method is relatively unreasonable, inconvenient for production and installation, and cannot be adjusted. Utility Model Content

[0004] The utility model aims to provide a baton which has a simple structure and connection mode and is easy to install.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A baton comprises a tubular grip, a telescopic rod which can be switched between a folded state in which the grip is folded and retracted and an unfolded state in which the grip is unfolded and extended, and a locking mechanism. The locking mechanism comprises a mounting seat and an elastic member. The mounting seat is fixedly arranged at the lower end of the grip, the elastic member comprises two elastic parts and a connecting part, the two elastic parts are relatively distributed and extend upward at intervals, the connecting part is connected between the lower ends of the two elastic parts, a slot for the connecting part and the lower sections of the two elastic parts to be embedded is formed on the side of the mounting seat, a pressure block for limiting the lateral separation of the elastic member from the mounting seat is provided on the mounting seat, the two elastic parts can restrain the telescopic rod so that the telescopic rod is kept in a folded state, during installation, the elastic member is inserted into the slot from the side of the mounting seat, and then the pressure block is installed to limit the elastic member from lateral separation from the mounting seat, and the connecting part will be blocked by the mounting seat, and the elastic member cannot be separated from the slot in the forward direction. The structure and connection method are relatively simple and easy to produce and install.

[0007] The telescopic rod comprises at least two tubes which are sleeved in sequence and whose diameters gradually decrease. The two elastic parts are inserted into the tube with the smallest diameter to keep the telescopic rod in a folded state. The at least two tubes can make the baton have a longer length when it is swung out.

[0008] The two elastic parts and the connecting part are integrally formed of elastic metal material, which can facilitate the production of the product.

[0009] The two elastic parts and the connecting part are sheet-like structures. The elastic part of the sheet-like structure has better bending resistance. After being inserted into the tube with the smallest diameter, the elastic force is larger due to the better bending resistance, so the telescopic rod can be well kept in a folded state.

[0010] The upper section of the elastic part is an outwardly protruding arc structure, which reduces the distance between the top ends of the two elastic parts and increases the distance between the middle parts of the two elastic parts, thereby guiding the tube with the smallest diameter to better cooperate with the elastic part.

[0011] The width of the slot is matched with the thickness of the elastic part and the connecting part, so that after the elastic part is installed in the slot, it can prevent the elastic part from shaking or shifting too much to a certain extent, thereby affecting the cooperation with the telescopic rod.

[0012] The mounting seat comprises a connecting section, which is inserted into the lower end of the gripping rod and is tightly matched with the gripping rod.

[0013] The connecting section is formed with an external thread, the lower end of the gripping rod is formed with an internal thread matched with the external thread, and the slot is formed on the side of the connecting section.

[0014] A mounting groove for the pressing block to be embedded in is formed on the side of the mounting seat, so that the pressing block can be embedded in the mounting groove after being installed, and will not affect the connection between the mounting seat and the gripping rod.

[0015] The mounting seat also includes a main body section, which has a conical window-breaking portion, and a metal window-breaking head is arranged at the lower end of the window-breaking portion. The connecting section and the main body section are integrally formed of a polymer, and the window-breaking portion is used to break the window. The connecting section and the main body section are made of polymer to reduce production costs and facilitate manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figures 1 to 9 As shown, a baton includes a tubular grip 2, a telescopic rod 1 which can be switched between a folded state in which the grip 2 is folded and retracted and an unfolded state in which the grip 2 is unfolded and extended. The telescopic rod 1 is specifically a first tube body 11 and a second tube body 12 which are sequentially sleeved and have gradually decreasing diameters. The connection between the first tube body 11 and the second tube body 12 can make the baton have a longer length when swung out, so that the attack range is wider. The outer peripheral surface of the grip 2 is provided with an anti-slip cover, which can increase the friction when the user grasps it.

[0026] The locking mechanism is also included. The locking mechanism includes a mounting seat 3 and an elastic member 4. The mounting seat 3 is fixedly arranged at the lower end of the grip 2. The mounting seat 3 includes a connecting section 32 and a main section 31. The connecting section 32 is inserted into the lower end of the grip 2 and is tightly matched with the grip 2. The upper end of the connecting section 32 is formed with an external thread, and the lower end of the grip 2 is formed with an internal thread matched with the external thread. When connecting, the connecting section 32 is threadedly connected with the grip 2. The lower end of the main section 31 has a conical window-breaking portion 311. The lower end of the window-breaking portion 311 is provided with a metal window-breaking head 312. The specific material of the metal window-breaking head 312 is tungsten steel. Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. The connecting section 32 and the main section 31 are integrally formed by polymer, specifically plastic or other polymers with a certain strength, which are not limited here. The window-breaking portion 311 is used to break the window. The use of polymers in the connecting section 32 and the main section 31 can reduce the production cost and facilitate manufacturing. A connection hole is formed at the bottom of the window breaking part 311, and the metal window breaking head 312 is cylindrical with a conical tip. When installing, the rear end of the metal window breaking head 312 is inserted into the connection hole, and the tip leaks outward. After the metal window breaking head 312 is inserted into the connection hole, the conical tip and the conical window breaking part 311 are smoothly transitioned. A through hole 313 is formed on the main body section 31, and the through hole 313 is used to set an anti-drop rope. When using, the user can put the anti-drop rope on his hand to prevent the baton from being taken away or lost.

[0027] The elastic member 4 includes two elastic parts 41 and a connecting part 42. The two elastic parts 41 are spaced apart and relatively distributed and extend upward. The connecting part 42 is connected between the lower ends of the two elastic parts 41. The two elastic parts 41 can be inserted into the second tube body 12 to keep the telescopic rod 1 in a folded state. The two elastic parts 41 and the connecting part 42 are integrally formed with elastic metal materials, which can facilitate the production of the product. The two elastic parts 41 and the connecting part 42 are sheet-like structures. The sheet-like elastic part 41 has a better bending resistance. After being inserted into the second tube body 12, the elastic force is larger because of the better bending resistance, which can well keep the telescopic rod 1 in a folded state. The upper sections of the two elastic parts 41 are symmetrically protruding outward in an arc-shaped structure. The arc-shaped structure makes the top ends of the two elastic parts 41 have a smaller distance, while the middle ends of the two elastic parts 41 have a larger distance. When the two elastic parts 41 are inserted into the second tube body 12, the arc-shaped structure can guide the tube body to better cooperate with the elastic parts 41, so that the arc-shaped elastic parts 41 can be better inserted into the tube body, and the inner wall of the second tube body 12 can be pressed tightly under the action of the elastic force when the distance between the two elastic parts 41 is the largest, thereby preventing the second tube body 12 from detaching from the elastic member 4.

[0028] The mounting seat 3 is formed with a slot 36 for the connection portion 42 and the lower sections of the two elastic sections 41 to be inserted. The slot 36 is formed on the side of the connection section 32. The mounting seat 3 is provided with a pressing block 33 for limiting the lateral separation of the elastic member 4 from the mounting seat 3. The side of the mounting seat 3 is formed with an installation groove 34 for the pressing block 33 to be inserted. In this way, the pressing block 33 can be inserted into the installation groove 34 after installation, and will not affect the connection between the mounting seat 3 and the handle 2. Fig. 9 As shown, the notch of the slot 36 is connected to the mounting slot 34, so that the pressing block 33 can press the elastic member 4 well after being installed.

[0029] During installation, the elastic member 4 is installed into the slot 36 from the side of the mounting seat 3, and then the pressure block 33 is embedded in the mounting groove 34 to limit the elastic member 4 from detaching from the mounting seat 3 from the side, and the connecting portion 42 will be blocked by the mounting seat 3, and the elastic member 4 cannot detach from the slot 36 from the forward direction. A first bolt hole 331 is formed on the pressure block 33, and a second bolt hole 341 is formed in the mounting groove 34 of the mounting seat 3. The bolt 35 is passed through the first bolt hole 331 and the second bolt hole 341 to fix the pressure block 33 and the mounting seat 3. Then the metal window breaking head 312 is connected to the window breaking portion 311 of the mounting seat 3. Finally, the upper end of the mounting seat 3 is aligned with the lower end of the gripping rod 2, and the mounting seat 3 is screwed into the gripping rod 2 through threaded engagement.

[0030] The structure and connection method are relatively simple and convenient for production and installation. The width of the slot 36 is adapted to the thickness of the elastic portion 41 and the connection portion 42, so that after the elastic member 4 is installed in the slot 36, it can prevent the elastic member 4 from shaking or shifting too much to a certain extent, thereby affecting the cooperation with the telescopic rod 1.

[0031] When in use, the baton is swung outward with force when the retractable rod 1 is in the folded position, and the second tube body 12 is freed from the elastic force of the elastic member 4 and can move toward the outside of the grip rod 2, driving the first tube body 11 to move together until the telescopic rod 1 is switched to the unfolded state; after use, the second tube body 12 is pressed down to drive the first tube body 11 to move into the grip rod 2 until the bottom of the second tube body 12 contacts the elastic member 4, and the two elastic parts 41 of the elastic member 4 are squeezed to deform so that the two elastic parts 41 are inserted into the second tube body 12, and the second tube body 12 is bound in the grip rod 2 under the elastic force of the elastic member 4, and the first tube body 11 cannot extend out of the grip rod 2 when the second tube body 12 is bound, and the telescopic rod 1 can be switched to the folded position.

[0032] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
