Description

Anti-pinch catch

Technical field

The utility model relates to a kind of wheel blocking means for preventing vehicle or aircraft from surprisingly sliding under halted state, especially It is a kind of anti-pinch catch for preventing vehicle or aircraft from surprisingly sliding under halted state.

Background technique

Many oversize vehicles or aircraft surprisingly slide in order to prevent when stopping all being arranged catch for its tire, especially Aircraft will block the rubber catch of triangle body structure in the front and back of aero tyre when stopping or wooden wheel is kept off, but It is due to topography out-of-flatness, when aircraft releasing of brake, aircraft may forward or be slided backward, so that the tire of aircraft is tight It is tightly pressed in above catch, since the quality of aircraft is big, and the corner angle of catch are very sharp, the meeting when we need to take out catch Extremely difficult, catch could be taken out by even needing to call in trailer dragging aircraft sometimes, be inconvenient.

Summary of the invention

The utility model is intended to that existing catch is overcome to be easy nipped deficiency, provides and a kind of meet requirement and prevent The catch of folder.

The utility model is achieved through the following technical solutions：A kind of anti-pinch catch, including body of rubber structure, installation Two support plates at body of rubber structure both ends, for support plate being mounted on the installation axle in body of rubber structure, installation Roller bearing between two support plates, the club being mounted on roller bearing and installation screw；The body of rubber structure is three Angle body structure, there are two the end faces of triangle and three rectangular bottom surfaces, each bottom surface to be both provided with antiskid groove for tool, main Body structure centre has the drawstring mounting hole axially penetrated through, and there are three perforative supports around the drawstring mounting hole of main structure Plate mounting hole is used to install support plate, respectively there is the arc-shaped groove structure hollowed out on three long arris；The branch Fagging is one piece of triangle metal sheet, and side length is slightly less than the side length of the section triangle of catch main structure, and three angles are fillet, It is equipped with a drawstring mounting hole in the centre bit of support plate, it is corresponding with the drawstring mounting hole of main structure to communicate, it is drawn for installing Rope, there are three mounting holes around drawstring mounting hole, corresponding with three support plate mounting holes in main structure to communicate, and are used to handle Support plate and main structure are installed together by installation axle, respectively there is a square roller bearing peace on three angles of support plate Filling hole can prevent roller bearing from rotating for installing roller bearing using rectangular pore structure；The installation axle is metal bar structure, two There is screw thread at end, and installation axle passes through the mounting hole on the mounting hole of main structure and the support plate at main structure both ends and passes through installation spiral shell Silk is installed together；The roller bearing is cylindrical structure, is equipped with installation screw thread at roller bearing both ends, is equipped with square on the inside of screw thread Mounting surface, fit through the support that roller bearing is mounted on main structure both ends by installation screw with the square mounting hole of support plate Between plate, and in the circular groove being located just on the long arris of main structure；The club is hollow cylindrical structure, Roller bearing smears lubricant across the support plate that club is mounted on main structure both ends between roller bearing and club, makes Obtaining club can be freely rotated.

Specific embodiment

Presently in connection with attached drawing, the present invention will be further described.

As shown in Figure 1 and Figure 2, a kind of anti-pinch catch, including body of rubber structure 2 are mounted on 2 both ends of body of rubber structure Two support plates 3, for support plate 3 being mounted on the installation axle 6 in body of rubber structure 2, be mounted on two support plates 3 it Between roller bearing 5, the club 1 being mounted on roller bearing 5 and installation screw；As shown in figure 3, the body of rubber structure 2 is three Angle body structure, there are two the end faces of triangle and three rectangular bottom surfaces, each bottom surface to be both provided with antiskid groove for tool 204, there is the drawstring mounting hole 202 axially penetrated through at 2 center of main structure, has around the drawstring mounting hole 202 of main structure 2 Three perforative support plate mounting holes 203 are used to install support plate 3, respectively have on three long arris one hollow out it is arc-shaped Groove structure 201；As shown in figure 4, the support plate 3 is one piece of triangle metal sheet, side length is slightly less than catch main structure 2 Section triangle side length, three angles are fillet, a drawstring mounting hole 303 are equipped in the centre bit of support plate 3, with main structure 2 correspondence of drawstring mounting hole 202 communicates, for installing drawstring 8, there are three mounting hole 302 around drawstring mounting hole 303, with Three support plate mounting holes 203 correspondence in main structure 2 communicates, and support plate 3 and main structure 2 is used to pass through installation axle 6 It is installed together, respectively there is a square roller bearing mounting hole 301 to adopt on three angles of support plate 3 for installing roller bearing 5 It can prevent roller bearing 5 from rotating with rectangular pore structure；The installation axle 6 is metal bar structure, and there is screw thread at both ends, and installation axle 6 is worn The mounting hole 302 crossed on the mounting hole 203 of main structure 2 and the support plate 3 at 2 both ends of main structure is installed by installation screw 7 Together；As shown in figure 5, the roller bearing 5 is cylindrical structure, it is equipped at 5 both ends of roller bearing and screw thread 502 is installed, in screw thread 502 Side is equipped with the mounting surface 501 of square, fits through installation screw 4 with the square mounting hole 301 of support plate 3 and pacifies roller bearing 5 Between the support plate 3 at 2 both ends of main structure, and the circular groove 201 being located just on the long arris of main structure 2 It is interior；The club 1 is hollow cylindrical structure, and roller bearing 5 passes through the support plate 3 that club 1 is mounted on 2 both ends of main structure Between, lubricant is smeared between roller bearing 5 and club 1, club 1 is freely rotated.

As shown in Fig. 1 Fig. 2, the anti-pinch catch of the utility model, when tire, which is pressed in wheel, to be blocked, three due to catch are long The sharp corner angle in side are substituted by rotary cylindrical club, when pulling catch, when by traditional catch and tire interface Sliding friction become rolling friction, it is possible to easily pull out catch, generate anti-pinch effect.
