[0047] Please refer to Figure 1-Figure 12 , this embodiment provides an emergency manual pump, including: a pump body 100, a support seat 200, a locking mechanism 300 and a supporting mechanism 400;

[0048] The support seat 200 is provided with a sliding slot 210 ; along the axial direction of the sliding slot 210 , the pump body 100 is slidably matched with the sliding slot 210 ; the locking mechanism 300 can fix the pump body 100 in the sliding slot 210 .

[0049] It should be noted that one end of the sliding slot 210 passes through the side wall of the support seat 200, thereby ensuring that the pump body 100 can be inserted.

[0050] Another thing that needs to be explained is that the pump body 100 adopts a conventional hand pump structure, and a hand handle is provided on a side away from the support seat 200 .

[0051] When in use, the pump body 100 can be inserted into the sliding slot 210 and fixed in the sliding slot 210 by the locking mechanism 300 , so that the pump body 100 is connected to the support seat 200 , and then the support seat 200 provides support for the pump body 100 .

[0052] Through the above design, the support seat 200 can be used to expand the contact area with the ground to provide better support force for the pump body 100. The locking mechanism 300 can effectively fix the pump body 100 to the support seat 200. The detachable connection method between the pump body 100 and the support seat 200 is more applicable and more portable.

[0053] In general, the emergency manual pump provided by the embodiment of the present invention is easy to use, convenient to install, and has good support, thereby making the manual pump more stable during use.

[0054] Specifically, the locking mechanism 300 includes a locking rod 310 and a locking spring 320. The support seat 200 is provided with a movable hole 220 connected to the sliding slot 210. The central axis of the movable hole 220 and the central axis of the sliding slot 210 form an angle A.

[0055] One end of the locking rod 310 can be moved through the movable hole 220 and then placed in the sliding slot 210. The locking spring 320 is sleeved on the locking rod 310, and one end of the locking spring 320 close to the movable hole 220 is connected to the locking rod 310, and the other end is connected to the support seat 200. The pump body 100 is provided with a locking groove 110 that matches the locking rod 310.

[0056] In this embodiment, a mounting groove 230 is provided at the bottom of the support seat 200, and the mounting groove 230 is parallel to the sliding slot 210. The locking rod 310 can movably pass through the mounting groove 230, and the locking rod 310 is provided with a limit baffle 330. The limit baffle 330 is located in the mounting groove 230, and one end of the locking spring 320 is connected to the limit baffle 330, and the other end is connected to the side wall of the mounting groove 230 away from the sliding slot 210.

[0057] In addition, a handle 340 is installed at one end of the locking rod 310 away from the sliding slot 210 to facilitate pulling the locking rod 310 to move along the axial direction of the movable hole 220 .

[0058] In some embodiments, the locking rod 310 is of a conventional columnar shape. When the locking spring 320 is in a natural state, the locking spring 320 stretches so that one end of the locking rod 310 passes through the movable hole 220 and enters the sliding slot 210. When the pump body 100 is inserted into the sliding slot 210, it is necessary to manually pull the locking rod 310 to the end away from the sliding slot 210. After the pump body 100 is inserted, under the action of the locking spring 320, the locking rod 310 is driven to move until the locking rod 310 is inserted into the locking groove 110 to achieve locking of the pump body 100.

[0059] In other embodiments, in order to further improve the degree of automation and realize automatic locking, an extension portion 350 is intentionally provided at one end of the locking rod 310 close to the sliding slot 210; along the axial direction of the locking rod 310 and the direction in which the pump body 100 is inserted into the sliding slot 210, the diameter of the extension portion 350 decreases;

[0060] The sliding slot 210 has an open end 211 and a closed end 212 . The pump body 100 is inserted into the sliding slot 210 through the open end 211 . When the pump body 100 contacts the closed end 212 , the extension 350 enters the locking groove 110 to lock the pump body 100 to the support seat 200 .

[0061] By designing the extension portion 350 and utilizing the inclined surface of the extension portion 350, when the pump body 100 moves toward the closed end 212 in the sliding slot 210, the main body can contact the inclined surface of the extension portion 350, thereby transmitting force to the locking rod 310, thereby driving the locking rod 310 to move toward the side away from the sliding slot 210 until the pump body 100 moves to contact the closed end 212. At this time, due to the design of the locking groove 110, the locking rod 310 loses force and is reset under the action of the locking spring 320, driving the extension portion 350 to move into the locking groove 110 to achieve locking of the pump body 100.

[0062] Furthermore, in this embodiment, in order to ensure the balance and stability of locking the pump body 100 , at least two locking components may be provided, and the two locking components are respectively provided on both sides of the sliding slot 210 .

[0063] In this embodiment, in order to further limit the pump body 100 inserted into the sliding slot 210 in the vertical direction, a limiting slot 240 is specially provided on both side walls of the sliding slot 210, and the central axis of the limiting slot 240 is parallel to the central axis of the sliding slot 210; and limiting plates 120 are provided on both sides of the pump body 100 to slide with the limiting slot 240. At this time, when the locking spring 320 is in the natural state, the extension part 350 is located in the limiting slot 240, and the locking slot 110 is provided on the limiting plate 120.

[0064] Through the design of the locking mechanism 300, the pump body 100 can be fixed to the support seat 200 in a detachable connection, thereby ensuring the stability of the pump body 100 when connected to the support seat 200, thereby making the manual pump more firm and reliable during operation.

[0065] In addition, in this embodiment, in order to further improve the stability of the support base 200, a support mechanism 400 for supporting is intentionally provided on the side of the support base 200 away from the pump body 100, and the support mechanism 400 has a plurality of support foot assemblies 410;

[0066] The plurality of support leg assemblies 410 are distributed in a circular array with the center of the support base 200 as the center of the circle, and the plurality of support leg assemblies 410 can be close to or far away from each other with the center of the support base 200 as the center of the circle.

[0067] Specifically, the support mechanism 400 includes a drive disk 420, a drive shaft 430, a housing 440 and a drive assembly 450, wherein the drive assembly 450 includes a drive gear 451 and a drive rack 452, one end of the drive shaft 430 can movably pass through the support seat 200 and then be connected to the drive gear 451, and the drive gear 451 is located in the sliding slot 210, the other end of the drive shaft 430 is connected to the drive disk 420, the central axis of the drive shaft 430 is perpendicular to the central axis of the sliding slot 210; and the extension line of the drive shaft 430 passes through the center of the support seat 200; the drive rack 452 is arranged on the pump body 100, when the pump body 100 is inserted into the sliding slot 210, the drive rack 452 is engaged with the drive gear 451 to rotate the drive gear 451.

[0068] A plurality of strip grooves 421 for mounting the support foot assembly 410 are provided on one side of the driving disk 420 away from the support seat 200. One end of the strip groove 421 is close to the edge of the driving disk 420, and the other end extends along the circumference of the driving disk 420 and is close to the center of the driving disk 420. Along the length direction of the strip groove 421, the support foot assembly 410 is slidably connected with the strip groove 421.

[0069] The housing 440 is connected to the support seat 200, and the housing 440 has a receiving cavity for receiving the driving disk 420; the housing 440 is provided with a plurality of strip-shaped limiting holes 441 cooperating with the supporting foot assembly 410, and the extension line of the length direction of the strip-shaped limiting hole 441 passes through the extension line of the driving shaft 430; the supporting foot assembly 410 passes through the strip-shaped limiting hole 441, and along the length direction of the strip-shaped limiting hole 441, the supporting foot assembly 410 is slidably connected with the strip-shaped limiting hole 441;

[0070] It should be noted that the housing 440 and the support base 200 can be connected in a detachable manner such as bolts, and the end of the driving shaft 430 away from the driving gear 451 is movably connected to the housing 440 .

[0071] Another thing that needs to be explained is that the strip groove 421 can be an arc-shaped structure or a straight strip shape.

[0072] It should also be noted that the diameter of the driving gear 451 is smaller than the width of the sliding slot 210 , and the height of the driving gear 451 is smaller than the height of the limiting slot 240 , thereby ensuring that the driving gear 451 does not interfere with the movement of the pump body 100 .

[0073] In this embodiment, the number of the strip grooves 421 is consistent with the number of the limiting strip holes.

[0074] In addition, in this embodiment, the support foot assembly 410 includes a support block 411, a sliding block 412 and a support foot 413. The support block 411 is arranged in the strip limiting hole 441 and is slidably connected to the strip limiting hole 441; one side of the sliding block 412 is connected to the support block 411, and the other side is slidably connected to the strip groove 421. The support foot 413 is arranged on the side of the support block 411 away from the sliding block 412.

[0075] The strip groove 421 has a first end portion close to the center of the driving disk 420 and a second end portion away from the center of the driving disk 420; when the pump body 100 is inserted into the sliding slot 210 and moves to the end of the stroke, the sliding block 412 moves to the second end portion, and the multiple support leg assemblies 410 move away from each other; when the pump body 100 leaves the sliding slot 210, the sliding block 412 moves to the first end portion, and the multiple support leg assemblies 410 move toward each other.

[0076] By setting the driving assembly 450, the linear motion of the pump body 100 when inserted into the sliding slot 210 can be utilized, so that the driving rack 452 and the driving gear 451 are meshed, so that the linear motion is transmitted to the rotational motion of the driving disk 420, and the driving disk 420 rotates so that the sliding block 412 slides with the strip groove 421. Based on the structure of the strip groove 421, the sliding block 412 is driven to generate a certain horizontal force. At the same time, under the limiting condition of the limiting strip hole, the support block 411 moves along the length direction of the limiting strip hole, thereby driving the support foot 413 to move;

[0077] When the pump body 100 is inserted into the sliding slot 210, the driving gear 451 rotates in the first direction, driving the driving disk 420 to rotate in the same direction, driving the multiple sliding blocks 412 to move from the first end to the second end in the strip groove 421, and then the support block 411 drives the support foot 413 to move in a direction away from the center of the support seat 200, so that the multiple support feet 413 move away from each other to form a spreading trend.

[0078] When the pump body 100 leaves the sliding slot 210, the driving gear 451 rotates in the second direction, driving the driving disk 420 to rotate in the same direction, driving the multiple sliding blocks 412 to move from the second end to the first end in the strip groove 421, and then the support block 411 drives the support foot 413 to move toward the center of the support seat 200, so that the multiple support feet 413 approach each other to form a contraction trend.

[0079] Through the above design, the linear motion performed when the pump body 100 is connected to the support seat 200 can be utilized to drive the drive disk 420 to rotate. The special structure of the strip groove 421 and the matching design of the limiting strip hole can convert the rotational force into horizontal forces in different directions, thereby realizing the mutual approach / distance of multiple support foot assemblies 410. In the working state (the support feet are away from each other), better stability and support are guaranteed. In the non-working state (the support feet are close to each other), the occupied space is reduced and it is convenient to carry.

[0080] In addition, in this embodiment, it should be noted that when the pump body 100 moves to the end point of the closed end 212 of the sliding slot 210, the sliding block 412 moves to the end point of the second end of the strip groove 421, and when the pump body 100 moves to the open end 211 of the sliding slot 210 (that is, when the driving rack 452 is separated from the driving gear 451), the sliding block 412 moves to the end point of the first end of the strip groove 421. This ensures that the maximum and minimum distances of the support leg assembly 410 move when the driving disk 420 rotates.

[0081] In general, the present invention can provide further support for the pump body 100 by setting up the support seat 200, and can ensure the stability of the connection between the pump body 100 and the support seat 200 through the design of the sliding slot 210, and can drive the locking mechanism 300 to move and lock the pump body 100 to an ideal position while the pump body 100 is connected to the support seat 200 by insertion, and can also drive the drive assembly 450 to move when the pump body 100 is installed on the support seat 200, so that the support mechanism 400 is stretched to further ensure the supporting force, and when the pump body 100 is separated from the support seat 200, the drive assembly 450 is driven to move in the opposite direction, so that the support mechanism 400 contracts; the automatic locking of the pump body 100 and the automatic opening and closing of the support mechanism 400 are realized through the connection between the pump body 100 and the support seat 200, which makes it more convenient and efficient to use.

[0082] The working principle of an emergency hand pump is:

[0083] ① When installing the pump body 100: remove the pump body 100 into the sliding slot 210, the limit plate 120 is located in the limit slot 240, and the pump body 100 is pushed to move toward the closed end 212 of the sliding slot 210. When the pump body 100 moves to the point where the drive rack 452 is meshed with the drive gear 451, the pump body 100 continues to move to drive the drive gear 451 to rotate, thereby driving the drive disk 420 to rotate, driving the multiple sliding blocks 412 to move from the first end to the second end in the strip groove 421, thereby causing the support block 411 to drive the support foot 413 away from the support foot 413. The seat 200 moves in the direction of the center, so that the multiple support feet 413 move away from each other to form a spreading trend; when the pump body 100 continues to move along the sliding slot 210 until the limit plate 120 contacts the extension part 350, the limit plate 120 pushes the locking rod 310 to move toward the side away from the sliding slot 210 to compress the locking spring 320. When the pump body 100 moves to the closed end 212 of the sliding slot 210, the extension part 350 contacts the locking slot 110, and under the action of the locking spring 320, the extension part 350 enters the locking slot 110, thereby locking the pump body 100.

[0084] ② When disassembling the pump body 100: manually pull the locking rod 310 to move toward the side away from the sliding slot 210 until the extension part 350 is separated from the locking slot 110, and then drag the pump body 100 to move toward the open end 211 of the sliding slot 210. At this time, the driving rack 452 continues to engage with the driving gear 451, driving the driving gear 451 to rotate in the opposite direction, driving the driving disk 420 to rotate in the same direction, and driving the multiple sliding blocks 412 to move from the second end to the first end in the strip groove 421, thereby making the support block 411 drive the supporting foot 413 to move toward the center of the support seat 200, so that the multiple supporting feet 413 are close to each other to form a contraction trend.

[0085] In summary, the present invention is easy to use, convenient to install, and has good support, thereby making the manual pump more stable during use.

[0086] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
