Description

Technical Field

[0001] The utility model relates to the technical field of disc brake pumps, in particular to an anti-loosening opposed cylinder disc brake pump structure. Background Art

[0002] Disc brakes consist of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, high-pressure brake oil pushes the brake pads to clamp the brake disc to produce a braking effect. Today, it is widely used for front wheels. Some high-end cars are equipped with four-wheel disc brakes. Its advantages are sensitive action, good heat dissipation, no need to adjust the brake clearance, and easy maintenance. The disc brake pump is one of the important components of the disc brake system.

[0003] The authorized patent with the known application number: CN202222766016.6 discloses a shock-resistant and anti-loosening motor vehicle disc brake pump, and its background technology proposes the problem that "after long-term use, the existing motor vehicle disc brake pump is prone to loosening of the screws on the motor vehicle disc brake pump due to the vibration of the vehicle, thereby affecting the stability of the motor vehicle disc brake pump during use, and even affecting driving safety in severe cases". To this end, the technical solution to this problem is "including a disc brake pump body, a mounting plate is provided at the front end of the disc brake pump body, a brake pad assembly is provided at the front end of the mounting plate, the output end of the disc brake pump body is connected to the input end of the brake pad assembly, mounting holes are provided at the four corners of the mounting plate, a first screw is provided inside the mounting hole, a first knob is provided at the front end of the first screw, and a first annular groove is provided on the outer wall of the first knob".

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned technical solution has the following problems: although it achieves the effect of preventing the screws (i.e., the first screw) on the disc brake pump from loosening through the provided technical solution, it is not convenient to quickly release the anti-loosening restriction of the first screw when in use. It restricts the first screw from loosening through the blocking block and the first annular groove. When the first screw needs to be disassembled for later maintenance of the disc brake pump, it is necessary to first use tools to twist the second screw one by one to separate the blocking block from the first annular groove before the anti-loosening restriction on the first screw can be released and disassembled. The operation process is relatively cumbersome and time-consuming, which can easily increase the maintenance time of the disc brake pump, thereby reducing the convenience of use and the efficiency of disassembly and maintenance of the disc brake pump. Utility Model Content

[0005] The utility model provides an anti-loosening opposed cylinder disc brake pump structure, which solves the problem in the related art that it is inconvenient to quickly release the anti-loosening restriction of the first screw.

[0006] The technical solution of the utility model is as follows: an anti-loosening opposed cylinder disc brake pump structure, comprising: a disc brake pump body;

[0007] A mounting plate fixedly installed on one side of the disc brake pump body, and mounting holes are provided at the four corners of the mounting plate;

[0008] Multiple groups of card slots symmetrically opened on one side of the mounting plate and located on both sides of the mounting holes;

[0009] A bolt rod threadedly connected in the mounting hole;

[0010] Two shells symmetrically and fixedly installed on the surface of one end of the bolt rod;

[0011] A clamping block rotatably connected in the shell and cooperatively inserted with the card slot;

[0012] A connecting rod hinged to the clamping block;

[0013] And an elastic mechanism arranged in the shell and connected to the connecting rod. The connecting rod drives the clamping block to make a rotational movement through the elastic mechanism so that its vertical section is clamped into or extends out of the card slot.

[0014] Preferably, the elastic mechanism includes a fixed rod fixedly installed in the shell, a slider slidably connected to the surface of the fixed rod, and a first spring sleeved on the surface of the fixed rod and connected to the shell and the slider at both ends respectively. One end of the connecting rod is hinged to the slider.

[0015] Preferably, a braking mechanism is provided on one side of the mounting plate, and the braking mechanism is used to brake the brake disc of a motor vehicle.

[0016] Preferably, the braking mechanism includes a limit seat fixedly installed on one side of the mounting plate and a braking component arranged on the limit seat.

[0017] Preferably, an annular inner groove is provided on one end face of the bolt head of the bolt rod, and a buffer mechanism for reducing the influence of vibration on the bolt rod is arranged in the annular inner groove.

[0018] Preferably, the buffer mechanism includes a second spring fixedly connected to the inner wall of the annular inner groove and a buffer pad ring fixedly connected to one end of the second spring and sleeved on the surface of the bolt rod. The buffer pad ring is made of rubber material and can undergo elastic deformation under external force.

[0019] The working principle and beneficial effects of the present utility model are as follows:

[0020] After the mounting plate is fixed, the clamping block is exactly aligned with the clamping groove at this time. Release the clamping block, drive the slider to reset through the first spring, and drive the clamping block to rotate and reset to the horizontal state through the connecting rod, so that its vertical section is inserted into the clamping groove to clamp and prevent the bolt rod from loosening. When disassembling the mounting plate to maintain the disc brake pump, just rotate the clamping block to separate it from the clamping groove to release the restriction on the bolt rod for disassembly. Therefore, the effect of preventing the bolt rod from loosening and quickly releasing the anti-loosening restriction is achieved. The operation process is simple and convenient, avoiding the situation that tools are needed to turn the screw rod to release the restriction, reducing the time consumed in the disassembly process, and effectively improving the use convenience and the maintenance efficiency of the disc brake pump.

Specific Embodiments

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0028] Please refer to Figure 1 - Figure 4 , the anti-loosening opposed cylinder disc brake pump structure provided by the present invention includes: a disc brake pump body 1;

[0029] A mounting plate 2 is fixedly mounted on one side of the disc brake pump body 1, and mounting holes 3 are provided at four corners of the mounting plate 2;

[0030] A plurality of sets of slots 4 are symmetrically arranged on one side of the mounting plate 2 and located on both sides of the mounting hole 3;

[0031] A bolt rod 5 threadedly connected to the mounting hole 3;

[0032] Two housings 6 are symmetrically fixedly mounted on the surface of one end of the bolt rod 5;

[0033] A card block 7 is rotatably connected to the housing 6 and plugged into the card slot 4, wherein the card block 7 is L-shaped, and the inner hole length of the card slot 4 is greater than the thickness of the vertical section of the card block 7;

[0034] A connecting rod 8 hinged to the clamping block 7;

[0035] And an elastic mechanism is arranged in the housing 6 and connected to the connecting rod 8. The connecting rod 8 drives the clamping block 7 to rotate through the elastic mechanism, so that the vertical section of the clamping block 7 is clamped into or extended out of the clamping slot 4.

[0036] The elastic mechanism includes a fixed rod 9 fixedly installed in the shell 6, a slider 10 slidably connected to the surface of the fixed rod 9, and a spring 11 sleeved on the surface of the fixed rod 9 and connected to the shell 6 and the slider 10 at both ends respectively. One end of the connecting rod 8 is hinged to the slider 10.

[0037] The technical solution provided by this embodiment is as follows: when in use, the mounting plate 2 is placed at a designated position on the motor vehicle, and the mounting hole 3 is aligned with the connecting hole at the position, and then the bolt rod 5 is screwed into the mounting hole 3 and connected with the connecting hole to achieve the purpose of fixing the mounting plate 2. When the bolt rod 5 is tightened, the clamping block 7 is driven to rotate so that it is turned from a horizontal state to an inclined or vertical state (the clamping block 7 can be reset to a horizontal state by limiting it with a finger), and the connecting rod 8 is driven to move so that the angle between the two changes. At the same time, the slider 10 is driven by the connecting rod 8 to slide along the surface of the fixing rod 9 to compress the spring 11. When the bolt rod 5 is tightened, the clamping block 7 is just aligned with the clamping slot 4. At this time, the clamping block 7 is released, and the connecting rod 8 is driven to move. The slider 10 is reset by the elastic force of the spring 11 itself, and the block 7 is driven by the connecting rod 8 to rotate and reset to a horizontal state, so that the vertical section of the block 7 is inserted into the slot 4 to clamp the bolt rod 5 to prevent loosening. Since the inner length of the slot 4 is greater than the thickness of the vertical section of the block 7, when disassembling the mounting plate 2 to maintain the disc brake pump, it is only necessary to rotate the block 7 to separate it from the slot 4 to release the restriction of the bolt rod 5 for disassembly. Therefore, the bolt rod 5 is prevented from loosening and the anti-loosening restriction is quickly released. The operation process is simple and convenient, avoiding the need to use a tool to twist the screw to release the restriction, reducing the time consumed in the disassembly process, and effectively improving the convenience of use and the maintenance efficiency of the disc brake pump.

[0038] Further, a braking mechanism is provided on one side of the mounting plate 2, and the braking mechanism is used to brake the brake disc of the motor vehicle.

[0039] The braking mechanism includes a limit seat 12 fixedly installed on one side surface of the mounting plate 2 and a braking component 13 provided on the limit seat 12.

[0040] Specifically, through the settings of the limit seat 12 and the braking component 13, it is convenient to clamp the brake disc of the motor vehicle to achieve the effect of braking the motor vehicle. Among them, the limit seat 12 and the braking component 13 are both well-known prior arts in the field, so no more details will be described here. Embodiment 2

[0041] Based on Embodiment 1, in this embodiment: an annular inner groove 14 is formed on one end face of the bolt head of the bolt rod 5, and a buffer mechanism for reducing the influence of vibration on the bolt rod 5 is provided in the annular inner groove 14.

[0042] The buffer mechanism includes a second spring 15 fixedly connected to the inner wall of the annular inner groove 14 and a buffer pad ring 16 fixedly connected to one end of the second spring 15 and sleeved on the surface of the bolt rod 5. The buffer pad ring 16 is made of rubber material and can undergo elastic deformation under external force.

[0043] The technical solution provided in this embodiment is: when the bolt rod 5 is screwed into the installation hole 3 to install the mounting plate 2, as the bolt rod 5 is screwed in, the buffer pad ring 16 contacts the mounting plate 2 and gradually squeezes the second spring 15. When the mounting plate 2 is fixed, the second spring 15 makes the buffer pad ring 16 closely fit the mounting plate 2 through its own rebound force. At the same time, the buffer pad ring 16 also fits the bolt head of the bolt rod 5. During use, through the cooperation of the buffer pad ring 16 and the second spring 15, the vibration force received by the bolt rod 5 can be buffered, avoiding the loosening phenomenon of the bolt rod 5 due to the influence of vibration, thereby further improving the anti-loosening effect and connection stability of the bolt rod 5.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
